WILLIAM H. cases, or PHILADELPHIA, PENNSYLVANIA.

MOTOR-CYCLE.

Application filed November 22,1905. Serial No. 288.536.

To all l whom it may concern: i 'Be it known that I, WILLIAM H. OREss, a

citizen of the United States, residing at .eration, thus giving a convenient rest for the feet of the rider, while maintaining the legs and body in a natural position, and by means of which the rider may standerect to relieve the body of shock and jars incident to I traveling over a roughroad-bed.

A further object of my invention is to put all of the operating mechanism under the control of the rider 'upon the handle-bars, so that the pedals may be thrown out of action,

the cranks of the sparker advanced. or receded and the back pressure without removing the hands from the handle-bars, thus at alltimes giving the rider perfect control of the machine. i -With these ends in View this invention consists in. the detailsof construction and combination of elements herein after set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention. appertains may understand-how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this s pecification, in which.

Figure 1 is a side elevation of a motorcycle having my improvements applied thereto; Fig. 2, a section of the fly-wheel casing and crankdisks; Fig. 3, a section at the line'm :1: of Fig. 2.

Referring to the drawings, A represents the frame of the machine, which may be of any ordinary construction, and to this frame is secured the engine B, the latter being bolted or otherwise secured to the fly-Wheel casingC,whichlatterisformedwith'theframe or may be brazed' thereto, as found best.

The two fiy-wheels D are connected by the Specification of Letters Patent.

, Patented oca e, ieoe.

crank E to which the connecting-rod F is attached, the upper end of the latter being connected to the piston of the engine in the usual manner, and these fly-wheels D have formed therewith the shafts G, which are journaled in the casing C, as clearly shown in Fig. 2. One of the shafts G has secured thereon the sprocket-wheel H, around which the chain I is adapted to run, said chain also running around a suitable sprocket-wheel J secured to the rear wheel of the machine, so that when the engine is operated the vehicle will be propelled.

K represents disks having internal gears formed therein, and these disks are journaled upon the shafts so as to revolve concentric therewith, and to each of the disks is attached a crank L, carrying suitable pedals'M. A shaft N is journaled in the casing and has secured u on one end the pinion O, which meshes with t e internal gear of the disk K, while on the opposite end of this shaft is fitted a similar pinion O, which is free to revolve upon the shaft N, and this last-named pinion meshes with the internal gear of the disk K. 1

' A clutch P is splined upon the shaft .N and adapted to be thrown into or out of engage= mentwith the pinion .0, so as to cause the latter to revolve with the shaft N or leave it free to revolve independent of said shaft.

A clutch-lever Q is pivoted'to the casing and engages with the clutch so as'tocontrol the sliding movements of the same, and the outer end of this lever has attached thereto the wireor cable ihwhich leads from suitable pulleys to the bell-crank lever S, the latter being pivoted to the head of the machine and connected withthe hand-lever T, which extends into easy reach of the rider when grasping the handle-bar. f

Thus it will be seen that when themachine is tofbe started the clutch is thrown into engagement with thepinion 0, thereby becoming rigid with the shaft N which will cause the two disks K and K to revolve in unison on account of the pinions O and O meshing with the internal gears of said disks, thus so connecting the cranks to cause them to revolve in-unison, and as the rider is supposed to have one of the cranks to its highest point while the other remains at its lowest point e crankswill be the same as in an ordinary bicycle. After the engine has been put into operation the throwing of the clutch P out of engagement with the pinion O, as before described, will disconnect the two crank-disks so that they may be revolved separate from each other, thus allowing both pedals to be brought to their lowest position to act as a rest for the' feet of the rider and to be utilized by him for standing erect when occasion requires. Power is transmitted from the disks Ix and K to the engine-shafts G, and consequently the fly-wheels, by train of gears U, j ournaled upon the frame 0, the outer member of said train meshing with the internal gear of the disk K, while the inner member of said train meshes with the gear 'V, secured upon one of the shafts G, so that when the crank-disks the shaft G, so that the engine when running will not revolve the disks K and K but when the latter are revolved they will effect the revolving of the fly-wheels D, and consequently the actuation of the engine W represents a small gear-wheel fitted to revolve upon a stud secured to the casing 0, this gear meshing with the internal gear of the disk K, and the hub of this gear has formed thereon a cam a, adapted to act upon the sparking lever b, so as to make and break the circuit in connection with the pin d. This making and breaking of the electric circuit is for the purpose of producing the ignitionspark for operating the engine, as will bewell understood.

To recede or advance the sparking, a suitable wire e is connected with the pin (1 and passing through suitable pulleys is connected with the hand-lever f in easy reach of the hand of the rider in grasping the handle-bars,

, so that by the operation of this lever f the pin may be thrown backward. A suitable spring is intended to carry it forward, thus enabling the rider to regulate the time of the s ark.

In'starting a gas-engine it is usua l v necessary to relieve the back pressure in order the t the engine may operated from the cranks of the machine, and for this purpose 1 provide relief-valve g at the top of the enginecylinder and-connect this valve by the wire hto the lever '1', located in easy reach of the rider when holding the liandlc-lnirs, so that this valve may be opened foriielieving back pressure while the engine is being started and then closed for maintaining the compression after the engine is in operation.

ln practice I prefer that the disks K and K be titted to run upon the l all-bcarings I, so as to reduce the friction thereof. 'lhcsc ball bearings may or may not be used, as best suits therequirements of the particular design ofv the machine.

Having thus fully described my invention, what I claim as new and useful is V 1. In combination with a motor-cycle, a casing, two shafts carried in said casing, a fly-wheel carried by each of said shafts, a crank connecting sprocket-wheel carried by one of the shafts for t-ransii'iitting power to the rear wheel of the machine through a suitable chain, two
