Improvements in Velocipedes, of which the following is a specification.

This invention has for its objects, primarily the-construction of a new and improved form of railway velocipede with motor actuating and at the same time as light as is consistent I with safety in operation, and to further pro- 15 vide an improved form of chain driving means for transmitting the power of the driving motor to said velocipede, which said chain driving means .will combine with the usualadvantages of a chain drive over other forms of power transmission of flexible character, the positive advantage as applied, of greater simplicity and freedom from slippage under-slight strains.

Another object of this-invention is to provide animproved form of driving connection between the motor and the driving wheel, such improved form of driving connection embodying a positive driving connection between the motor shaft and the large driven 3O gear or sprocket, and a slip clutch connection to take care of unusual stresses such as might be incident in cases of accident, or jar or shock, such for example as often occur in the starting of the motor. 1

A further object of this invention is to provide an improved form of throw-out mechanism for disengaging the hand driving gear, so that after the machine has started and the engine has come into operation, the hand mechanism can be readily disconnected and locked in the desired position. Still another object of this invention is the provision. of an improved form of reinforced framework which will satisfactorily withstand the shocks of service and not have a tendency to spread or to break at the connections, or collapse under stress or in col lisionsj.

Stillanother object ofthis invention is the revision of an improved means whereby at the time the hand. driving mechanism is:

- thrown out, the gear of the same maybe locked so as to retain the operating handle in any desired position, according to the will of the operator; that is to say in any osition which will most naturally and com ortably suit his height and convenience.

The above as well as such other objects as will hereinafter appear, I attain by means of a construction w ch I have illustrated in preferred form inthe accompanying draw- I ings, wherein- Figure 1- shows in side elevation an improved motor driven railway velocipede with my invention ap lied'thereto;

Figure 2 is a p an view of the same;

Figure 3'is an end elevation of my improved construction;

Figure ft is a view of the details connected with the driving means for transferring the power of the motor to the forward driving 7 wheel Figure 5 is a sectional view of said detailed driving device indicated in Fig. 4;

Figure 6 is another detailed view indicating the mounting of the hand driving gears and the devices employed for throwing them into and out of engagement;

Figure 7 is another view similar to Figure 6, but indicating the parts in position for driving operation.

Figure 8 1s a sectional View indicating another elevation of the mechanism shown in Figures 6 and 7, and

Figures 9 and 10 are elevation and inverted plan view respectively of the preferred, shaft mounting. of the forward driving wheel.

Referringnow more particularly to- Fig. ures 1, 2, and 3, it will be seen that incarry ing out my invention I provide first the rear driving wheel 9 and the forward driving wheel 10, with a third wheel 11 and the fourth wheel 12 for running upon the other rail, said wheels 11 and 12,being mounted on the ends of connectingbars 13 and M which are held; by means of the diagonal brace 15 and the connecting rod 16, and secured as shown, with adjustable means. I

The main frame of the mechanism con sists primarily of upper and lower longitudinal bars marked respectively 17 and 17 and 18 and 18, between which pairs of bars 17 and 18, and 17* and 18 are mounted the secured as shown, between the hand lever 26 and the forward. driving wheel,and having a chain 21 running from a pinion 22 on the engine or motor shaft to a large s rocketwheel 23 on the axle of the forward riving wheel.

At the rear of the hand lever 20 is arranged the operator's seat 24, and back of this exmotion from an idler gear 29 that is in turn driven from a .gear 30, the latter receiving its power from the cranks 31 and connections 32, from the hand'lever 20 which is pivoted to the frame as shown, and also connected by means of the rod connections 33 to the foot treadles 34 which are suspended by the links 35 in the usual manner.

In order to. provideconvenient means for throwing the gear 30 into and out of engagement, I mount the said gear upon a shaft 30* shown more in detail in Figures 6, 7, and 8, which shaft is provided with the eccentrics 36 carried in brackets 36 mounted upon the lower bars of the frame. as shown, and as a means for moving said eccentrics I provide levers 37v connected by bars 38 to the lower ends-of the levers 39 which being" fast to the r'ockshaft 4O canbe readily moved by the operator, throu h the hand lever 40*, so as to secure artia rotation of the said eccentries 36 w ich move the gear 30 into and out of engagement with the gear29. The eccentrics 36, the boxes 36 F, and the levers 37 and l 39, and other parts referred to, are all made in pairs as shown, and carried by the respec- 40 tive side bars of the frame, while the ear 30 is carried intermediate the two side liars of the frame. upon the shaft 30*.

I From examination of the structure above described, itwill'be evident that the drivinggear which is carried on-the shaft, which latter is' nioufnted'in the eccentric, will have a motion that will bring the teeth of the gear into engagement with its cooperating gear,

m a direction transverse totheaxis of rotation of the ear; that is to say, longitudinall' of the atter, instead of by slidin the teet into' and outof engagement, by irection of motion parallel with the axis of rotation. By'this provision I secure the object of shifting the gears. into..and out -of opera t-ive position with less danger of'damage to the same, such as oftenflresults inshifting arranged the mechanism indicated in Figure 6, which employs a projection or stop. 39 which as shown, is carried by one of t e levers 39, and is adapted to engage with any of the teeth on the said gear 30, to hold it' in any desired position, said sto 39 coming into such engagement when t e. lever 39 is moved to the position shown in'said Figure '6, so as to shift the gear out of engagement.

It will be seen that by the use of this looking arrangement which prevents the rotation of the gear 30 and consequently any movement of drivin handle 20 and; the foot treadles 34, the and-driving lever and foot.

treadles may be locked in any desired portion of their stroke, thus providing adjustable'restsfor the hands and feet when the motor is running, and it is not desirous to utilize the handles or treadles as driving means, or when coasting. I

In order to provide a means which will compensate for undue jars or'shocks, and.

relieve the driving chain from damaging effects thereof,-'I arrange mechanism indicated in Figures 4 and Sin detail, wherein 41- indicates the web. of the forward driving wheel 10 which is carried upon an axle 42 by means 'of a center piece 43 held upon the conical part 44 by means of the nut 45; The largesprocket wheel is composed of the. central.

part or s ider 46 with the detachable toothed ring 47 eld by the cap screws 48, and pro vided with a smooth machined face arranged to bear against a fiber disk 49 which in turn on its opposite face bears against a steel late 50,- so as to provide a frictional contact Between the chain sprocket and the-driving wheel in the transmission of power. other fiber disk is arranged. rat-.51, pressed by the metal washer 52 through -.the lnstru'mene tality of the screw nuts 53 which are mount ed about the shaft 42 and arra ed to be locked in any desired. position to etermine the compression or pressure operating upon the fiber disks. a 1

It, will-thus be seen by the arrangement last described that in carrying out my invention I provide-a slip connection between the motor and the wheel which is driven thereby, to take care of uneven stresses, and yet which will be at all times in engagement, and which does not involve the employment of any com licated clutch mechanism or con--.

character, which I I 120 necting evice of other find to be undesirable.

- In order to cause the machine to track properly and obviate any tendencyjto-climb the'rail, such as is sometimes es e'cially ob servable 1n the case of the smal er wheel on wheels opposite the driving sideI provide an improved mounting for the shaftof the forward motor actuated driving wheel-saidmountln as shown'in'Figures 9, and-10',

v part 64. carrying the set screws small wheel 11 tends to climb the rail, suchdisconnecting the hand driving connection,

forshifting said hand driven mechanism intospur gear,

- combinatiom-a driven wheel, adriving spur '65 and took nuts '66 to s'erve as a means for adjustin the position of the blocks 60 longitudinally of the frame. By proper setting-of the angle of the axle of the forward wheel or, as it is. called, ointin the wheel, the desired tracking of the madhineis secured. If the outer tendency can be readily overcome by simply pointing the flange of the forward driving wheel a little more toward its own rail.

The mechanism just described further serves as a means to adjust the slack of the drive chain. i

It will be understood that the. term vehout in itsgeneric employing foot driving means, drivencars of this general character being generally ing means areomitted.
