1901-1919      1920 - 1930       1930--1938

For a small company Riley seems to have spent its time patenting new designs after many were simply copied and probably after being ripped off by Kirkwoods over the bicycles. Apologies for really anorak/nerd stuff  but it actually shows the designs were a family effort NOT just Percy and  that Allan and Victor actually had a higher profile than Styles credits. Much of this data is really for museum cars but may be useful and as Google Patents is a subsection of books it made sense to use it. Drawings included for those rebuilding something from the earlier days of motoring

**All entries are precis of the full patent which may stretch to many pages and numb the mind. I have included the precis plus the drawings and a link to the archived article. For the complete drawings when following the link to Espacenet press drawings or for the full paper work select original document etc. These amplify the positions of the various sons within the company reflecting a true family business**

INCORRECT AS THE Patent Office has it as invented by

GB 21,689. Victor + Percy Riley,  aka 'Improvements in or relating to Driving, Free-wheeling and Braking Mechanism for Velocipedes and the like'.

Patented Oct. 6th 1902 .A Back-pedalling brake.  Brakes; clutches; driving - mechanism. -A free-wheel and back-pedalling brake mechanism for bicycles and other velocipedes &c. comprises a pawl cage (A pivoted curved bar or lever whose free end engages with the teeth of a cogwheel or ratchet so that the wheel or ratchet can only turn or move one way. Yes I did not have a clue either so looked it up)  [16], having a limited rotary movement relatively to the sprocket-wheel, and a brake, the band [41] of which, fixed at-one end to one of the curved arms [40], is adapted to be expanded into frictional contact with the flanges [35] of the hub. The cage carries two sets of oppositely-directed pawls [19], [20] actuated by the springs [24], [25] and provided with projections [29], [30], which, by engagement with slots [13], [14] in the sleeve [11], hold the pawls out of action. The springs [25] are stronger than the springs [24], and in the rest position, the pawls [20] are held in engagement with the teeth [27] on the sleeve [12]. The springs [25 also force the studs [30] back against the slots [14] bringing the slots [13] against the studs [29] and so closing the pawls [19] down against the action of their springs [24]. On forward-pedalling, the pawls [2] first drag in the teeth [27], and, as the sleeve [11] turns forwards, the slots [13] tend to leave behind the studs [29, and the driving-pawls [19] are raised by their springs into engagement with the teeth [26] in the hub [4], the driving-pins [15] on the collar [5] picking up the pawl-carrier [16]. The forward rotation of the sleeve [11] relatively to the carrier causes the slots [14] to act on the studs [30] and draws the braking-pawls [20] down clear of the teeth [27]. To increase the dragging effect, springs [44] may be introduced, and the springs [25] need not then be stronger than the springs [24]. In free-wheeling, the parts assume their rest position and the hub rotates free of contact with the closed down pawls [19]. Backward pressure on the pedals is transmitted to the sleeve [12] through the pawls [20] and teeth [27], and the backward rotation of the sleeve causes the flat faces of its end to become turned, so that, through the projection [42] or the rollers [43] on the arms [40], the band [41] is expanded into contact with the hub, and braking occurs. In wheeling the machine backwards, the hub rotates without disturbing the mechanism.

GB190314391 (A) - Percy Riley  Improvements in or relating to Internal Combustion Motors.

20. August 1903 Engine valve gear.  images on page 342 of Styles /Old as the Industry and the full description on pages 343-345 >
My invention relates to internal combustion motors such as used on motor tricycles and other automobiles; and has for its objects to provide simple means for operating both the inlet and the exhaust valves mechanically,. and for holding open one or other of such valves when required. And in order that the manner in which I attain my objects may be properly understood I will describe the same with the aid of the. accompanying drawings, wherein.
Figure I is a side elevation of part of an internal combustion motor fitted with valve operating mechanism constructed according to my invention, the cover plate being omitted to disclose the mechanism. Figures III and V are similar views showing modifications. Figures II and IV are detail views in plan.. . Figure VI is a front elevation of the valve operating and holding mechanisms shown in Figure V. The same numerals refer to the same parts throughout the drawings.
I  operate both the inlet valve and the exhaust valve from one shaft and according to the method of carrying out my invention shown in Figs. I and II, as applied to a four phase internal combustion motor [2] provided with the usual half speed shaft [3], I mount upon the said shaft two cam projections, one (Fig 4) . of comparatively wide angle for actuating the exhaust valve [5], and the other (6) of comparatively narrow angle for actuating the inlet valve [7]. The valves may have their stems arranged parallel to one another and be. provided with the usual return springs. The valve stems work in guides  [ 8], and plungers [9] carried in (other guides [19] operate upon the feet of the said stems. On a pivot [10], the axis of which is parallel to and may be in line with the axes of both the crank shaft [11] and the half speed shaft [3], I mount two rocking arms [12], [13], each of which is provided with two striking faces, viz [14] and [15] on the arm [12], and ]I3] and [17] on the arm [13]. The striking faces [14], [16] are adapted to be operated upon by the cam projections [4] and [6] respectively, and the faces [15 and [17] are adapted to operate upon the feet of the plungers [9] of the exhaust valve [5] and the inlet valve [7] respectively. The striking surfaces of the respective faces are preferably suitably curved, and the arms [12], [13] are set at suitable angles.
In action, as the half speed shaft [3] rotates the cam projection [6] operates upon the arm [13 which transmits the -motion to the plunger of the inlet valve [7]. and the combustible mixture is admitted to the cylinder. As the cam projection [6] leaves the said arm [13 the inlet valve is closed by its spring and the mixture is compressed by the return stroke of the piston, both the inlet and the exhaust valves for the time being remaining closed. The charge is next fired, and,preferably  before the driving stroke of the piston is completed, the cam projection [4] commences to act upon the arm [12] which transmits the motion to the plunger 'of the exhaust valve [5] and the said exhaust valve is held.open during the remainder..of that stroke and until the end of the next return stroke, when the earn projection [4]. leaves the said arm [12], and the series of operations is repeated..
  Upon the stud or the like [10] upon which the arms are pivotted I mount a sleeve [20] (Fig. II) which preferably passes through the cover [21], if any, enclosing the valve actuating mechanism. Upon the outer end of the said sleeve I secure a lever [23] by which the same may be.rotated.through a suitable angle, and upon the inner end of the said sleeve I provide a projection [23] adapted to engage a corresponding projection [24].upon  preferably the arm [12] of the exhaust valve operating mechanism.Normally  the sleeve' [20] and lever' [22] stand in such a position that the projection [23] on the sleeve clears the projection [24] on the arm; but when it is desired to hold open the valve [5] the sleeve [20] is rotated by the lever [22] until the projection [23] obstructs the projection [24] and holds up the arm [12] and with it the exhaust valve [5].
      According to the method of 'carrying out my invention shown in Figs. III and IV, I operate both the valves from the one half speed shaft [3], as before,, but provide it with a single cam projection [46] of comparatively narrow' angle. The arms [26], [27] operating the plungers [9] of the respective valves [5],[7] are pivotted upon separate studs [28], [29] with the ends carrying tho striking faces [30], [32] overlapping. The single cam [46] operates upon both the arms [26], [27] and is made wide enough for that purpose; and in order to obtain the proper periods cf holding open the inlet and exhaust valves respectively I make the striking faces [30], [32] which come in contact with the cam projection [46] of different lengths or angles, the face [32] on the inlet valve arm [27] being comparatively short or narrow, and the face [30] on the exhaust valve arm [26] being comparatively long or wide. The striking faces [31] and [33] operating upon the plungers of the exhaust and inlet valves respectively are preferably set over into the axial lines of those valves as shown in Fig. IV. ' When the cam projection [46] operates upon the arm [27] and inlet valve [7] is held open for a comparatively short period, while when the said cam projection operates upon the arm [26] - the exhaust valve [5] is held open 'for a comparatively long period.
    In this case one of the valves, may be held open by a lever [35] pivotted to the plunger guide [19] and provided with projections [36] on its upper surface adapted to engage a collar [37] .or other stop upon the plunger [9] when the said lever is raised, but the said collar or the like normally clears the said projections.
     The method of carrying out my invention shown in Figs. V and VI is more particularly applicable to motors in which the valves are arranged in a plane parallel to, instead of at right -angles to, the crank shaft. I employ a single half-speed shaft [3] and a single cam [4] to operate both the valves [ and [, but the two arms [42] .and [41], which are pivotted on the stud [42], are in one piece. The arms [40] and [41] are provided with striking faces [43] and [44 of dimensions adapted to the respective periods of the exhaust and inlet valves respectively which they are adapted to operate. The arms [40] and [41] are connected, as by the link [45], to a lever [47] pivotted at [48] and provided with striking faces [49] and [50] adapted to act upon the plungers [9] of the exhaust valve [5] and inlet valve [7]. respectively. When the cam projection. [46 operates on the striking face [44] the arm [41] is raised and the arm [40] is depressed. Consequently the adjacent end of the lever [47] is depressed and the other end, i.e the end carrying the striking face [50], is raised and the inlet valve is held open for a. suitable period, while the striking face [49] falls away from the plunger of the exhaust valve [5]. The charge is next com- pressed and 'exploded. Then the cam .projection begins to 'operate on the striking face [43], when the arm [40] is raised and the arm [41] is depressed. The raising of the arm [40] causes the raising of the striking) face [49 and hence opens the exhaust valve 5, while the striking face [50 falls away from the plunger of the inlet valve [7]. The same means may be employed for holding open the exhaust valve as shown in Fig. III.    
The valve operating mechanism shown in F. gs. V and VI may be adapted to a motor in which the valves are arranged in a plane at right angles to the crank shaft, by setting the axes of the half speed shaft [8] and stud [42] in the central transverse plane of the motor, and providing the arms [40] and [41] with striking faces [49] and [50] (indicated by dotted lines in Fig. V) adapted to operate directly upon the plungers of the respective valves..
I do not confine myself strictly to the above description but hold myself at liberty to make such modifications and applications of my invention as fairly fall within the scope thereof; the method of varying the periods during which valves operated from a single cam projection may be operated being, in pa.rticular, capable of being carried out in other ways and applied to other similar purposes.

GB190314392 (A)  - Victor Riley -  Improvements in or relating to Free Wheels and other Gear Wheels of Velocipedes.

30 July 1903 / June 29. Gear hardening   Clutches.-Free and other gear-wheels for velocipedes are hardened except as to the centres, which are left soft so that they may be readily bored and tapped to suit the ends of driving-wheel hubs or the like. The ring [2] is bored with a small hole and carbonized to a suitable depth, as shown in Fig. 1. The bore of the hole is then increased but still kept smaller than that likely to be required, and the thickness of the ring is reduced to its finished size. The ring is again heated and this time quenched, when the outer parts [4] are hardened, while the part around the hole from which the carbonized metal has been removed remains soft.

GB1904 20344   Sept. 21. 1904   Percy Riley  Improvements in Steering Gears for Motor Vehicles or the like.

Steering gear Motor road vehicles.-Steering-gear is described in which a toothed sector carrying a cam-groove is rotated by a bevel-wheel on the steering-column and communicates motion to a bell crank, one arm of which engages the cam-groove and the other is connected to the steering-wheels by any suitable mechanism. Figs. [1] and [2] show one arrangement of parts; the bevel pinion [B] on the steering- column rotates the toothed sector [C] around its pivot [D] in the oil-tight casing [A]. A roller [G<1>], mounted on the arm [G] of a bell-crank lever, engages the cam-slot [C<1>], eccentrically cut in the face of the toothed sector, and operates the other bell -crank arm H which transmits the motion to the steering-wheels. The steering-pillar may comprise a tube working on a rod fixed to the casing [A], or the tube may work outside a second tube through which rods may be passed for operating other mechanism on the vehicle. 1904-09-21 Application filed by Percy Riley 1904-09-21 Priority to GB190420344T 1905-07-27 Application granted 1905-07-27 Publication of GB190420344A  Status Expired



GB1904 20597   1904  Sept. 24  Percy Riley   Expanding ring clutch

 Motor road vehicles.-Comprises an expanding- ring type of clutch or brake, in which a wedge is normally pressed by a spring against rollers on expanding arms, thereby forcing the latter to engage an internal clutch surface. In Figs. [1] and [2], the invention is shown in the form of a clutch for a motor vehicle. The driving-shaft [A] carries a clutch drum [B], which may form the flywheel of the engine, and is extended to form a thimble bearing for the end of the driven shaft [C.] To this latter shaft is secured a disc [E] having lugs [E<1>], [E<2>], and also on its circumference spring-arms [F], [F<1>] which may be cast in one piece with the disc and afterwards separated from it nearly all round the circumference. The free ends of the spring- arms carry rollers which are engaged by the wedge [H] and are normally pressed into engagement with the inner surface of the clutch drum [B]. The wedge [H] extends diametrically across the disc [E] and has a slot at the centre to enable it to slide in the lugs [E<1>], [E<2>] it also carries a cross-bar [K] to which is fastened one end of the springs [L], the other ends being adjustably secured to the bar [J] fastened to the lug [E<1>]. The sliding sleeve [N] on the driven shaft is operated by the driver to force the wedge out of engagement with the clutch rings through the medium of the bell-crank lever [M].


GB1904 20860T  Sept. 28 1904   Percy Riley,   Gearbox (Tricar)  Improvements in Change Speed and Reversing Gears particularly applicable to Motor Vehicles.

 Motor road vehicles.- Relates to step-by-step change-speed and reversing clutch toothed gearing in which the Driving and driven shafts are co-axial and clutched together to give one speed, each of the other speeds being obtained through a separate countershaft. Figs. [1], [2], and [3] show a form of gearing giving three forward speeds and one reverse. The ends of the driving and driven shafts [A], [D] may extend into and support one another, and the driving- shaft [A] carries two toothed wheels [B], [C], the wheel [C] being formed with clutch jaws [C<1>] adapted to be engaged by jaws [E<1>] formed on a broad toothed wheel [E which rotates with but slides longitudinally on the driven shaft [D]. A reduced speed is obtained through toothed wheels [G], [H<1>], mounted freely on the countershaft [F], which gear continually with the wheels [B], [E], the sleeve on which the wheel [H<1>] is mounted being moved longitudinally so that clutch jaws [H<2>] formed on it engage jaws [G'] formed on the wheel [G]. Another speed is obtained similarly through wheels mounted on the countershaft [F<1>]. The reverse speed is obtained by means of two toothed wheels [J'], [J<2>] fixed to a freely-rotating sleeve [J, the wheel [J<1>] being continually in gear with the wheel [C] on the driving-shaft, and the wheel [J<2>] with the wheel [L which is freely mounted on the countershaft F ; the gear is brought into action by moving the sleeve carrying the wheel [H<1>] so that the clutch jaws [H<3>], [ L<1>] engage. The sliding of the various parts is preferably brought about as follows :-Each sliding part is connected by a fork to a sleeve [N] mounted on a fixed spindle M and acted on by a spring which tends to force the sliding part into engagement. Arranged transversely to these rods [M] is a shaft [0 carrying cams with recesses [ O<1>] which allow the springs to press the sliding parts into engagement when the cam shaft is in the proper position. For reversal, the sliding sleeve [H] is pressed into position by a camswell [O<2>]. The cam shaft is provided with a pinion [P ]engaging a sector [P'] which is suitably operated from the speed lever. In a modified construction, shown in [Fig. 6], suitable for a tri-car, the driving- shaft [A<1>] passes through the gear box, and carries the hollow driven shaft [D<2>, which is provided with a chain sprocket [D'] and toothed wheel [E']. The direct drive is obtained by moving the pinion [C<1>], keyed on the driving-shaft, until clutch jaws formed on it engage with similar jaws on the wheel [E<1>]. The reduced speeds and reversal are obtained through countershafts as in the first construction. The method of operation by sliding the several parts is similar, but the rotating cam shaft is replaced by a longitudinally-sliding rod [O<3>], having recesses for the forward speeds, and operating a rocking lever for the reversal.

GB1905   24211   Nov. 23. 1905   Percy Riley   Shaft-driven differential.Improvements in or relating to the Driving and Differential Gearing, and also the Driving Axles of Motor Cars.

Motor road vehicles.-Relates to the driving and differential gear of motor-cars. In the form shown in horizontal section in [Fig. 3], the differential gear is mounted on a short countershaft [E<1>], arranged parallel to the axle and carried in a casing [C] forming part of, or attached to, the axle structure. The countershaft [E<1>] is driven from the longitudinal transmission shaft [O<1>] through equal sized bevelgear wheels [O], [N], and drives the planetary pinions [G of the bevel differential gearing through the cross-piece on which they are mounted. The driven members of the differential gear drive the parts of the axle [A] by means of readily removable gear wheels [K], [K<1>], [B], [B<1>] so that the speed ratio can be adjusted. The gear wheels [B], [B<1>] are fixed on the ends of the axle in the manner shown in [Fig. 4]. The axle is formed with a boss or bosses [A<2>] which fit into slots in a boss [B<2>] formed on the gear wheel. A modification is shown in which the differential gear is placed to one side of the casing and is driven from the longitudinal shaft through skew-bevel gearing.Application events 1905-11-23 Application filed by Percy Riley 1905-11-23 Priority to GB190524211T 1906-02-22 Application granted 1906-02-22 Publication of GB190524211A

GB190813857A  June 30. 1908       Percy Riley    Improvements in or relating to Easily Detachable Road Wheels.

Detachable wheels ;hubs.-In detachable wheels having fixed and removable hub parts, the drive is transmitted direct from the live axle to the removable hub. The axle [A], [Fig. 1], has made integral with it or fixed to it a dog [B], flanged over as at [B'], on to which screws the fixed hub [C] enclosing the bearings [G]. The detachable hub [D], fixed hub C, and dog [B' are notched radially and engage a floating disk [F] with projections [E,] [Fig. 2].

. Detaching from and attaching to permanent hubs.-A nut 1, Fig. [1], for securing and withdrawing a detachable wheel comprises concentric cylindrical parts [2], [3], connected by a part [4] forming a housing for a spring-pressed ring [6] having teeth to engage similar teeth on the detachable wheel hub and pins 10, with inclined surfaces [13], which project through holes in the part [4] and through slots [12], Fig. [8], with inclined surfaces [14] in a ring [9], which is rotatable relative to the hub [1] for the purpose of withdrawing the locking-ring [ 6] from engagement with the teeth of the detachable hub. The cylindrical part [3] of the nut has an upstanding flange [ 22] on its inner edge, and wide notches are cut across the periphery thereof, including the flange, and narrow notches [24] are cut in the periphery of the rotatable ring [9]. The spanner [25], Figs. [12] and [13], has projections [26] on its inner periphery which fit the notches [24] in the rotatable ring and have a certain amount of play in the notches on the nut, segmental flanges [27], equal in length to the notches in the nut, at its inner side, and plates [28] at its outer side. In unscrewing the nut, the movement of the spanner fir,t actuates the ring [9], thus disengaging the locking-ring, and bringing the segmental flanges [27] behind the flange [22] on the nut, which is subsequently turned by the engagement of the spanner projections [26] with the ends of the notches therein. When screwing-up the nut, in the event of the locking-ring failing to become properly engaged with the teeth of the detachable hub, the pins [10] project in front of the plates [28] on the spanner and prevent it from being moved into the position in which the segmental flanges [27] coincide with the notches in the nut, which is the only position in which the spanner can be removed. The rotatable ring is held in position by a spring-pressed ball carried by the nut and engaging a depression in the ring. A cover-plate [15] is non-rotatably connected to the nut by projections [16] and screws passing through slots in the ring [9], or by other suitable means, and has apertures to guide the pins [10]. In a modification, Figs. [16], [17], the locking-pawls [29] are carried by a spring-controlled ring [30] which is moved outwards by inclined surfaces [32] on the spanner engaging behind lugs [33] thereon. In this case also the spanner can be removed in one position only, in which position plates [34] carried on the outer face of the spanner come over the lugs [33], this being impossible unless the pawls are in their locking position.

This invention relates to improvements in internal combustion engines of the type in which a number of cylinders are arranged around the crank shaft, the axes of the cylinders and the crank shaft being parallel. -The improvements relate more especially to the valve mechanism and to the means for converting the reciprocating motion of the pistons into the rotary motion of the crank shaft.

According to this invention motion is transmitted from the pistons to the crank through the medium of connecting rods each connected by a universal joint to a crosshead supported in gimbals carried by a bracket on the cylinder casting whilst being incapable of rotation relatively to the cylinders so that as the pistons work up and down in their respective cylinders the crank is rotated. The crosshead is connected to the single crank pin near the crank which pin is set at an angle .of about 25 ; the end of the crank pin is fast with a spindle which is coaxial with the crank shaft and actuates mechanism for operating the valves. Preferably I key to the spindle a disk having upon it skew teeth meshing with skew teeth on wheels turning on fixed bearings; there is one of these wheels for each cylinder and fast with the wheel are cams adapted to actuate tappets which are parallel with the spindle and which operate the inlet and exhaust valves.

COMPLETE SPECIFICATION. Improvements in Internal Combustion Engines. I, PERCY RILEY, of Castle Works, Coventry, Engineer, do hereby declare the nature of this invention and in what manner the same is to be perFormed, to be particularly described and ascertained in and by the following statement :-

This invention relates to improvements in internal combustion engines of the type in which a number of cylinders are arranged around the crank shaft, the axes of the cylinders and the crank shaft being parallel while motion is transmitted from the pistons to the crank through the medium of connecting rods each connected by a universal joint to a hollow crosshead supported in gimbals carried by a bracket on the cylinder casting while being incapable of rotation relatively to the cylinders so that as the pistons work up and down in their respective cylinders the crank is rotated. The crosshead is connected to the single crank pin near the crank which pin is set at an angle of about 25 ; the end of the crank pin is fast with a spindle which is coaxial with the crank shaft and actuates mechanism for operating the valves.

     According to this invention I employ in a 2-cycle engine a number of working cylinders in which combustion takes place and an equal number of pumping cylinders which are used for drawing in air, or gas and air, and pumping it into the working cylinders under normal conditions or for receiving air or gas and air under pressure for starting the engine. The spindle carries eccentrics operating two valve discs arranged outside the cylinder cover. The outer face of the outer valve works against a cover plate bolted to the cylinder cover and containing valve ports for admitting the gas or gas and air, hereinafter referred to as the mixture, to the pumping cylinders an inlet pipe for the mixture and an annular receiver into which the mixture is pumped by the pumping cylinders and thence at the proper time admitted to the working cylinders. At the end of their out strokes the pistons of the working cylinders uncover exhaust ports. If desired the pumping cylinders may be arranged to draw in air only which' scavenges and charges the working cylinders, the fuel being injected into the cylinders by a separate pump. Lubrication may be performed in any known manner such as mixing oil with the fuel or oil may be fed to the valve discs, pistons and bearings under pressure. The engine can also be made reversible by mounting the eccentrics on spiral keys so that by sliding a sleeve laterally on the eccentric shaft the eccentrics and consequently the valve motion can be either advanced or retarded.

According to my invention also I provide two sets of cylinders arranged tandem ~to~ work on- the same crosshead or I may~provide two crossheads to work tandem on two cranks on the same shaft or I may provide two crossheads and foursets of cylinders. In a 4-cycle engine the cylinders are all working cylinders and I preferably provide them with ordinary mushroom valves, the inlet and exhaust valves being identical. These valves are operated by tappets which are parallel to the spindle before mentioned and are actuated from that spindle by two to one skew gear. My invention is illustrated by the accompanying drawings,. Figure 1 is a sectional elevation of a 2-cycle engine constructed in accordance with my invention and having four working and four pumping cylinders. Figure 2 is a section on the line A-A Figure 1; Figures 3 and 4 show the inner and outer valve discs. Figure 5 shows diagrammatically an engine having two crossheads working on two crank pins on the same shaft, each crosshead being operated by two sets of cylinders arranged tandem.- Figure 6 is a sectional elevation of a 4-cycle engine and Figure 7 an end view thereof partly in section. 1 is one of four working cylinders and 2 is one of four pumping cylinders. The trunk pistons [3] of all these cylinders are connected to rods [4] which have at their outer ends balls [5 held in sockets [6 in a crosshead[7. On the cylinder casting [8] is a pair of brackets [9] pivoted to which is a ring [10] which can also pivot on a rod [11] arranged at right angles to the pivots of the brackets and entering bearings in the crosshead [7] so that the crosshead can wobble as the pistons work in and out but cannot rotate. [12] is the crank shaft rotatable in bearings 13 carried by the crank case 14 bolted to.the cylinder casting. The crank shaft is made in one with a crank disc 15 on which is a crank pin [16] set at an angle of about 25 and passing through bearings 17 carried by the crosshead [7]. The end of the crank pin remote from the disc is attached or formed in one with a spindle [18] coaxial with the crank shaft and with the line about which the cylinders are grouped. The rod [11] is bifurcated near its middle point so as to enable it to pass this spindle as clearly seen in Figure 2. 'The spindle has upon it 2 eccentrics [19 and 20 actuating inner and outer valve discs [21] and [22]. The outer face of the valve [22] works against the cover plate [23] bolted to the cylinder cover [24] and has formed in it ports [25]. The inner valve [21] works between the outer valve and the cylinder cover [24] and has openings [26] formed in it. Mixture is admitted through the opening [27] to an annular space [ 28]. in the cover plate [23] in which is also formed an annular receiver [29].

     The cycle of operations for the pumping cylinders is as follows:- Commencing with the piston at the inner or valve end, the valve [22 will admit mixture from the space 28 through one of its ports [25]; the mixture - passing through the valve [21] and through a passage [30 in the cylinder cover [24 is drawn into the pumping cylinder 2. On the piston reaching the outward end of its stroke the valve [22] closes the inlet and opens the passage [30 to the receiver [29 and the piston compresses the contents of the pumping cylinder into the receiver.

         The cycle of operations for the working cylinders is as follows : - When the working piston is near the outward end of its stroke the exhaust port 31] is uncovered and a little later the valve 21 uncovers the inlet port [32] leading from the charged receiver [29] to the working cylinder thus admitting the mixture which drives out the burnt products through the exhaust port, the inlet port remains open during part of the inward stroke of the piston. The inlet port then closes, the mixture is compressed and at or near the end of the stroke, is fired by any convenient means. The fired charge drives out the piston until the exhaust ports arc again uncovered which completes the cycle.

             The cycle of operations for starting the engine by means of compressed mixture is as follows:- One of the inlet passages [30] leading to the pumping cylinders must necessarily be open. The mixture passing through this passage drives out the piston rotating the crank shaft until the next passage opens. As the pumping pistons move inwards they discharge the mixture into the receiver which in turn charges the working cylinders, ignition then takes place and the engine commences to operate in its normal manner. Figure 5 shows an arrangement with two crossheads and crank pins arranged tandem on the same shaft with two sets of cylinders working on each crosshead. In the 4-cycle engine shown in Figures 6] and 7 the arrangement of the crosshead, shaft and spindle are the same. Each cylinder has similar inlet and exhaust valves [32] and [33] worked by levers [34] rocked by rods [35] from tappets [36] actuated by cams [37] rotated by two to one skew gears [38] from a common skew gear [39] fast on the spindle [18]. Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is: - 1. An internal combustion engine having a plurality of working cylinders and a plurality of pumping cylinders arranged alternately round a crank shaft and valve discs actuated by eccentrics on the shaft to control the admission of mixture to the pumping cylinders and from them to the working cylinders substantially as described.

This invention relates to improved valve mechanism for internal combustion and other engines and has for its object to allow a disk valve to correctly. register with ports in the cylinder head and valve cover. According to this invention an eccentric rotating disk provided with ports in its face and with teeth on its periphery gears with a portion of a ring of teeth on the cylinder head. The invention is mainly applicable to multicylinder internal combustion engines and the invention will be more fully described with reference thereto, but it is also applicable to steam and other engines. '

Thus in a seven cylinder four stroke internal combustion engine of the type , described in the Specification No. 18,204 of 1914 in: which a number of cylinders are arranged around a crank shaft and in which each cylinder has an inlet port, an .exhaust port and a starting port, the inlet and exhaust ports of all the cylinders are placed concentrically, and equidistant around the cylinder head while the starting ports are similarly arranged in a smaller circle. The eccentric disk is provided with six ports arranged concentrically and equidistantly around its face and adapted to operate the. inlet and exhaust and also with six concentrically arranged ports adapted to operate the starting ports. The disk is mounted on an eccentric driven by an eccentric shaft from the crank shaft through gearing in such a manner that the crank shaft makes two revolutions to one revolution of the eccentric while the teeth, on the periphery of the disk are geared to the teeth on the cylinder head as six is to seven so that the disc will rotate one sixth of a revolution, but in the opposite direction for each revolution of the eccentric. The inlet and exhaust ports of a cylinder are operated successively by two adjacent ports in the disk, thus a port in the disk will operate the exhaust of one cylinder and move towards the next cylinder nearer the next port in the disk will then operate the inlet port of the first cylinder and pass to a position between and out of the circle of the two ports for the compression and firing stroke and so on for the exhaust and inlet ports of the other cylinders. A non-return valve is placed in the starting ports to prevent blowing back. The order of firing is as usual 1, 3,5, 7, 2,4, 6.

COMPLETE SPECIFICATION. Improved Valve Mechanism for Internal Combustion and other Engines.

This invention relates to improved valve mechanism for internal combustion and other engines and has mainly for its object to allow a disk valve to correctly register with ports in the cylinder head an valve cover. According to this invention a disk valve arranged as a strap on an eccentric and having teeth gears with a fixed ring of teeth. The invention is mainly applicable to multi cylinder internal combustion engines and the invention will be more fully described with reference thereto, but it is also applicable to steam and other engines. In the drawings, Figure 1 is a section of a seven cylinder four stroke internal combustion engine in which the cylinders arc placed around the crank shaft. Figure 2 is an end view of the valve mechanism, the valve, cover being removed and Figure 3 is a .similar view in which the eccentric has made one half revolution.

      In the drawings, (1, is a crank shaft! similar to that shown in my former Patent No. 1.8,204. of 1914 and 1 to 7 are the seven cylinders arranged around it. [G] is a shaft driven from the crank shaft a through gear wheels cl, c2, C3, '1;,1 such that the crank shaft a makes two revolutions to one of an eccentric d mounted on the shaft [b]. [e] is a cylinder head provided with seven inlet ports [f] and seven exhaust ports g arranged concentrically and equidistant. [h] are seven starting ports similarly arranged but in a smaller circle.. [i] is an internal ring of teeth on the cylinder head [e].[ j] is a valve cover bolted to the head [e] and similarly provided with ports. [ k] is a disk valve mounted as a strap on the eccentric [d] and located between the head [e] and rover [j].

      This disk is provided with six ports arranged concentrically and equidistant around its face and adapted to open the inlet ports [f] and exhaust ports [g] and also with six concentrically arranged ports [m] adapted to open the starting ports [h]. Each port 1 is divided by zit. partition into two parts to prevent communication between an exhaust and an inlet port when a port l[] is partly in line with both at the same time.

  The disk [k] is provided with teeth [n] on its periphery which engage with the ring of teeth on the cylinder head [e]. The teeth n are to the teeth [i] as six is to seven so that the disk will rotate one sixth of a revolution but in the opposite direction for each revolution of the eccentric [d]. The valve mechanism works as follows:- The order of firing is 1, 3, 5, 7, 2, 4, (i ; the eccentric [d] moves clockwise and it will be seen by comparing Figures 2 and 3 that when the eccentric has moved half a revolution the port l1 has passed over the exhaust port ,,, of, cylinder [l] during the exhaust stroke; during the next half revolution the port 12 Will pass over the inlet port  [f] of cylinder [I] during the inlet stroke and then take a position out of the circle of the. inlet and exhaust ports for the compression and firing strokes. The path of the port 1 1 for a quarter, three quarters and one revolution is shown in dot and peck lines in Figure 3.

    The same cycle of operations takes place for the other cylinders, the starting ports being- covered and uncovered. in the same way, non-return valves, not shown in .the drawings, being provided in these ports to prevent blowing back. When starting the engine compressed air is supplied from a reservoir to the ports [m] and admitted to each cylinder in turn, thus revolving the crank until a charge is drawn in and fired. One starting port [m] will in a multi-cylinder engine be open whatever may -be the position of the crank. Figures 4 and 5 illustrate the invention as applied to a two-cycle steam engine. The general arrangement is similar to that shown in Figures l,2 and 3 and the same parts are marked with the same letters. In this engine the eccentric d. is mounted on the crank shaft cm; the gearing', however, of the teeth 7 on the disk [k] with the teeth [i.] on the cylinder head [c] is not altered, but the crank is advanced 60 ,on. the eccentric [d], The disk [k] is provided with six ports for operating the inlet ports f while exhaust takes place when the disk no longer covers an exhaust port [g]. Thus, in Figure 5 the admission of cylinder l is open, those of cylinders 2 and 7 partly so, while those of cylinders 3,4, 5 and 6 are closed. Similarly the exhaust ports g of cylinders 4 and 5 are open, those of cylinders 3 and 6 are partly closed, while those of cylinders 1, 2 and 7 are closed.

Disk wheels ; hubs.-A wheel of the single-disk type is secured to, or formed in one with, the hub cap. In one construction, [Fig. 1], the disk [1] is riveted to the hub cap [7], and is shaped at the periphery to form one part of the rim [2]. A strengthening-piece [3] is welded or riveted to the disk, and the other part [4 of the rim is secured bv bolts [5]. In another construction, the disk [1] and hub cap are formed integral, and the periphery of the disk is flanged and welded or otherwise secured to the rim [10. Reinforcing-disks [11] of decreasing diameter are added to give additional strength to the wheel.

GB150795A    June 4, 1919  Riley (Coventry) Ltd & Harry  Rush  Improvements in wheels for vehicles

 Disk wheels.-Dished wheels comprise two or more disks [1], [2] spaced apart at the hub by a ring [4] and braced intermediate the hub and rim by a series of washers [5] and rivets [6] or by a ring. In one construction, the disks are dished in the same direction to different angles, and in an alternative construction one of the disks may be fiat. [Fig. 3] shows a further modification in which only one disk [1] extends the full depth of the wheel, a second disk [7] of less diameter being riveted to the disk [1] at its periphery, and a third disk [9] of still smaller diameter being riveted at its periphery to the disk [7]. The disks are mutually spaced at the hub by rings [4], and the disks [1] and [7] are braced at an intermediate part by a ring or washers [5] and the rivets [10] that secure the smallest disk.
