VEHICLE DRIVING-GEAR SPECIFICATION forming part of Letters Patent No. 570,395, dated October 2'?, 1896.

Application filed September 16, 1895. Serial No. 562,660. (No model.)

To all whom it Wtcty concern:

Be it known that I, FRANK W. HAVILAND, of New York city, in the county and State of New York, have invented a new and Improved Vehicle Driving-Gear, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved vehicle driving-gear, arranged to propel the vehicle independently of the running wheels, and at the same time preventing any slip and consequently preventing loss of the power applied.

The invention consists principally of an independent friction-surface applied so as to utilize the weight of the 'vehicle to increase friction and overcome inertia and resistance.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure l is a sectional side elevation of the improvement on the line l 1 of Fig. 3. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view of the gearing. Fig. 4i is an end elevation of a modified form of the improvement, with part in section. Fig. 5 is a perspective view of a modilied form of the shifting arrangement for the propellingwheels. Fig. 6 is a side elevation of a modied form of the improvement as arranged for railroads. Fig. 7 is a side elevation of a modified form of the driving mechanism. Fig. 8 is an end elevation, with parts in section, of a modified form of the improvement. Fig. 9 is a plan view of a modified form of asteering device as applied, and Fig. 10 is a sectional side elevation of the same.

The vehicle on which my improvement is applied is provided with the usual body A, mounted on the front and rear axles A' and A2, on which are journaled the front and the rear wheels AS and A4, respectively. The

frame B is supported from the axles A' and A2, below the body A, and on this frame is mounted a motor C, of any approved construction and connected by a pitman C' and crank-arm C2 with a shaft D, journaled in `secured on a transverse shaft H, likewise journaled in, suitable bearings in the frame B. On this shaft I-l is fastened a sprocketwheel I, over which passes a sprocket-chain I', also passing over a sprocket-wheel I2, secured on the axle or shaft J of a wheel J, adapted to move with its peripheral surface in contact with the ground on which the vehicle travels.

The shaft J is located approximately directly below the rear axle A2, and the said 'shaft is journaled in an arm K, mounted to swing loosely from the shaft l-l as its fulcrum. The arm K is provided with an extension L, pivotally connected with a lever L', extending upwardbetween the cushions of the seat A5 to engage one of a series of notches L2 for locking the said lever in position. Now it will be seen that when the operator seated on the seat A5 presses the lever L' rearwardly in the direction of the arrow a' he causes a downward swinging of theV arm K to move the peripheral surface of the wheel J in contact with the ground, and the impact between the said peripheral surface and the ground is not in proportion to the pressure applied on the lever L', but dependsupon the angle of the arm K being such as to permit the wheel J to cramp under the vehicle, automatically increasing the impact upon the ground by Vutilizing the weight of the vehicle and so produce friction sufficient to overcome its own inertia or resistance when the wheel J is put in motion.

When the motor C is set in motion, a rotary motion is given to the shaft D, and the motion of the latter is transmitted, by means of the gear-wheels E, E', or E2, to the corresponding gear-wheels G, G', or G2, so that the shaft H is rotated, and the rotary-motion of ICO the latter is transmitted by the sprocket wheel I, the chain I', and sprocket-wheel I2 to the shaft J' and wheel J to revolve the latter in the direction of the arrow Zn. Now, as the wheel J is pressed firmly in contact with the ground, as previously described, and rotates in the direction of the arrow Z9', it propels the vehicle forward, and all slip in the propelling-wheel J is prevented by the peculiar cramping of the wheel J on the angular arm K, as above described. It is understood that when the operator shifts the lever F the speed of the wheel J will be increased or diminished, with the motor, however, running at a regular uniform speed.

In order to permit of running the vehicle backward, I provide the shaft D with a sprocket-wheel N, over which passes a sprocketchain N', also passing over a sprocket-wheel N2, secured'on the outer end of a shaft O', carrying a wheel O, arranged in front of the wheel J, and likewise adapted to move in Contact with the ground at the time the wheel J is raised, and as the said wheel O is adapted to travel in the direction of the arrow c' a rearward motion is given to the vehicle whenever said wheel O is in contact with the ground and is driven from the shaft D, the latter still revolving in the same direction as that in which it revolved before.

The wheel O is journaled in an arm P, mounted to swing loosely on the shaft D as a fulcrum, and the arm P is provided with a lever P', adapted to be enga-ged by the lever L by moving the arm K, so that a single forward movement in the inverse direction of the arrow d' causes an upward swinging of the arm K and a lifting of the wheel J out of contact with the ground, and at the same time causes a downward swinging of the arm P to move the wheel O in contact with the ground. The lever P' is under the control of the operator seated on the seat A5, and isl adapted to engage one of a series of notches P2 for locking the said lever in place. By the arrangement described the operator can work both levers L' and P' independently of one another, and also by the use of the lever L' he can throw the wheel O in contact with the ground, it only being necessary for the operator to move the lever L' a sufficient distance in the inverse direction of the arrow d'.

The shaft D can be driven by an auxiliary power or motor, here represented by footpowcr of the operator seated in the seat A5, and both the motor C and the foot-power may be employed to rotate the said shaft. For this purpose I provide the shaft Q, eX- tending transversely and journaled in suitable bearings in the frame B, the said shaft being provided with sets of crank-arms Q' and Q2, standing in opposite directions, as is plainly indicated in Fig. 3. The crank-arms Q' and Q2 are pivotally connected by links Q5 and Q4, respectively, with foot-levers Q5 and Q5, respectively, fulcrumed at Q7 to the fram'e B, the said levers extending upward through slots in the bottom of the body A to carry at their upper ends foot-pieces Q5, adapted to be engaged by the feet of the operator seated on the seat A5. New by imparting a forwardand-backward swinging motion tothe said levers and Q5 a rotary motion can be imparted to the shaft Q, and this rotary motion is transmitted by a gear-wheel R, fitted to slide on and to turn with a gear-wheel R', secured on the shaft D. Thus when the shaft Q is rotated the shaft D is likewise rotated to rotate both of the wheels J and O and to propel the vehicle forward or backward, according to which of the two wheels is in contact with the ground.

The gear-wheel R is adapted to be shifted on the shaft Q to move it out of mesh with the gear-wheel R', and for this purpose I engage the said gear-wheel R on its hub R2 by a shifting-lever R5, pivoted at R4in the body- A and under the control of the operator seated on the seat A5. The lever R2 is adapted to be locked in place in one of a series of notches The gear-wheel R, when shifted transversely by the said lever R5, can be moved out of engagement with the gear-wheel R' and in gear with the gear-wheel S, having its hub S mounted loosely on the shaft D. On the hub S' are secured two graduated gearwheels S2 and S3, adapted to be engaged by gear-wheels S'l and S5, respectively, secured on a hub S5, mounted to slide on and to turn with the shaft H, said hub being also engaged by a shifting-lever S7, fulcrumed at SS in the body A and adapted to be locked in place in one of a series of notches S9. Now it will be seen that when it is desired to transmit the rotary motion imparted to the shaft Q by the auxiliary power or feet of the operator, as previously explained, directly to the shaft Il without the use of the shaft D and the motor C then the operator first shifts the lever R5 to move the gear-wheel R in mesh with the gear-wheel S, and he then shifts the lever ST to move either of the gear-wheels S4 or S5 in mesh with the corresponding` gearwheel S2 or S3. The rotary motion of the shaft Q is now transmitted by the gear-wheel R to the gear-wheel S and by either of the sets of gear-wheels S2 S4 or S3 S5 to the shaft II, which imparts a rotary motion to the wheel J, as previously explained.

In order to actuate the arm P from the lever L' at the time the arm K is swung upward, I may employ the device shown in Fig. 5, in which the lever L3, connected with the arm K', is provided with a pin L4, engaging a slot L5 in an arm L5, attached to the shaft D, so that the forward movement of the lever L3 causes a forward swinging of the arm LU on the shaft D to swing the arm P downward, so as to move the wheel O in contact with the ground at the time the other wheel, J, is raised off of the ground.

The wheel J may be driven from the shaft H by different means than the sprocket wheels and chains above referred to; for` in- IOO IIO

stance, as shown in Fig. el, in which the shaft II carries a gear-wheel T, formed on its inner surface with two beveled gear-wheels T and T2 of different diameters and adapted to be engaged by beveled gear-wheels T4 and T5, held on the same hub T6, fitted to slide on and to turn with the shaft U, journaled in suitable bearings on the arm K.. The hub T6 is adapted to be shifted on the said shaft U by a suitable hand-lever T7 to move either of the pinions T4 or T5 in contact with its respective gear-wheel T or T2. On the lower end of the shaft U is secured a beveled gearwheel U', in mesh with a gear-wheel U2, secured on a shaft J', carrying the wheel J. Now by this arrangement a fast or slow movement can be given to the wheel J from the shaft I-I, the latter rotating at a uniform rate of speed.

As illustrated in Fig. G, the improvement is applied to a railroad-truck V, provided with a driven shaft V', on which is fulcrumed the lever V2, carrying a hand-lever V2, adapted to engage a segment V4 to lock the said lever in place. The lower end of the lever V2 is provided with two arms V5 and V6, of which the arm V5 carries the wheel J2, and the' other arm carries the wheel O2. Now by shifting the lever V2 either of the said wheels J2 or O2 will be moved in engagement with the rail on which the truck V travels. The wheels J2 and O2 are driven by gear-wheels from a gearwheel V7, secured on the shaft V', it being understood, however, that the latter is driven from a motor, which can be reversed, so as to rotate the shaft V' and gear-wheel V7 in either direction.

When the gear-wheel V7 travels in the direction of the arrow d@ then the wheel J2 is driven in the right direction for propelling the truck V forward at the time the said wheel J 2 is in engagement with the rail. IVhen it is desired to move the truck V in the inverse direction, or backward, then the lever V2 is shifted to the right to swing the wheel J2 out of engagement with the rail and the other wheel, O2, into engagement with the rail., The

shaft V is now driven in the inverse direction of the arrow d to cause the wheel 0 2 to move the truck V backward. The shaft V can, however, be driven by a movement which is non-reversing, and in this case (see Fig. 7) a gearing is employed similar to the one shown and described relative to Fig. 4, so that further description is not deemed necessary.

In Fig. 8 the arm K and lever L are shown as part of one of the axles WV of the vehicle, and for imparting a rotary motion to the wheel J. In this case the axle supports a loose gear-wheel W', in mesh with a gearwheel W2, secured on the shaft J s for the wheel J2, it being understood that the gearwheel W is also in mesh with a corresponding gear on shaft H.

The teeth of the gears on shafts H, D, and

Q are beveled at the ends to form clutchgears and to facilitate sliding in and out of mesh.

The steering device shown is more especially designed for vehicles carrying heavy loads, and this device is provided with a segmental gear-wheel Z, secured at its ends to the shaft-clips of the front axle and in mesh with a pinion Z', held on a vertically-disposed shaft Z2, carrying on its upper end a handwheel Z2, under the control of the operator.

Now by turning' the hand-wheel Z2 the pinion Z revolves the segmental gear-wheel Z, and the front axle is consequently turned to the right or left to cause the vehicle to travel in the same direction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l.
