DRIVING MECHANISM FOR AUTOMOBILES.-

SPECIFICATION forg' 108.147 of Letters Patent NO. 685,658, dated October 29, 1 901.

Application filed December 3, 1900. Serial No. 38,407. (No model.)

To all whom, it may concern:

Be it known that I, ROLLIN H. WHITE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of 5 Ohio, have invented a certain newand useful Improvement in Driving Mechanism for Automobiles, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings.

[ The invention relates to the driving mechanism for automobiles. It does not relate to the motor, but to the mechanism whereby its motion is made effective to drive the vehicle under-the varying conditions incident'to the use of such machines.

In the drawings, Figure 1 is a side elevation of an automobileembodying my invention. Fig. 2 is a plan view of the same, the vehicle-body'and some of the parts supported thereby being indicated by dotted lines only.

Fig. 3 is a rear elevation. Fig. 4 is an enlarged side viewof the brake-operating mechanism. Fig. 5 is a plan view of the throttlevalve. Fig. 6 is a side elevation, partly in 2 5 section, of said Valve. Fig. 7 is a rear view of the rear axle and a longitudinal sectional view of the parts which are immediately associated therewith.

Referring to the parts by letters, A represents the vehicle-body, and H represents the frame on which it is supported by the four sprihgs F F F F. The frame H consists of two side bars h h, the front transverse bar 71 and an arched transverse rear bar h.

3 5 These bars are suitably fastened together and are preferably made of steel tubes. The front springs F F are clipped to the front bar 72. and the two rear springsare clipped to the rear bar h.

The rear or driving axle D is rotatably mounted in two sleeves O C, which are pivotally connected to the ends of the arched bar It, said pivots being transverse to the axle and substantially horizontal. The ends 5 of the bar 7% are forked, and the forks h embrace said sleeves'and receive the pivots 0 These sleeves arethe outer non-rotatable members of the ball-bearings for the axle, the rotatable members being cones c c on the axle. The fixed and adjustable cups 0 c in said sleeves form, with said cones, a raceway in which antifriction-balls are confined.

At least one of said cones, however, is slidable lengthwise on the axle between shoulder d thereon and the hub of the adjacent wheel g which is secured to the axle. The bar h will straighten out more or less, especially when the vehicle is passing over a rough road, and the balls would be pinched and would bind in their bearings except for the possible longitudinal movement of one entire bearing on the axle. The movable cone 0 is connected to the axle by alongitudinal tongue 0 and groove 0 The rear axle is made in two parts 01 d arranged in axial line, with suitable washers d, if desired, between their adjacent ends. Loosely embracing one of these members is a sleeve 6, having at one end a disk 6, with a cylindrical flange e at its periphery. A simi- 7o lar sleeve a loosely embraces the other axle member, and it has a disk or flange e", which is secured to the cylindrical flange referred to, thereby forming an inclosed gear-case E,

surrounding the adjacent ends of the two axle members. Two beveled gears 01 d are secured, respectively, to the ends of said axle members within said casing, their faces being toward one another. One or more beveled gears e are mounted on radial studs e in the gear-casing, and they mesh with both bevelgears on the two axle members. These intermeshin g bevel-gears attached to two alined axle members and to a device rotatable upon said membersis in itself old and its function is well known. The specific construction shown, however, is believed to be new and to be specifically an improvement over the prior constructions. The outer periphery of the cylindrical flange is utilized as a braking-sure 9o face, which is embraced by a band-brake. The long sleeves e e of the two separable parts of said casing act to keep the two shaft members in alinement, and each carries a cone g forming part of a ball-bearing, which will 5 be presently described. A sprocket-wheel 6 which is, as shown, merely a rim with sprocket-teeth on its outer peripheryfisbolted to one side of the gear-case by the same bolts which fasten the two members of the gearcase together.

The shaft M of the engine is mounted in downwardly-extended arms m, which are parts of a frame rigidly fastened to the vehicle-body. A swinging frame K is supported from these arms, its axis being concentric with the axis of the shaft M. A sprocketwheel and attached gear 70 are fast on a shaft k which is rotatably mounted in the lower end of said swinging frame. The gear 70 meshes with a gear m on the shaft M, and a sprocket-chain O transmits motion from the sprocket-wheel It to the sprocket-wheel 6 The desired distance between the axes of these two sprocket-wheels is maintained by brace P, which consists of a bar 29 and the yoke-pieces 1119 secured, as shown, to the ends of said bar. The two ends of the yokepiece ptake over the ends of cylindrical projections on the swinging frame, which are axial with respect to said sprocket-wheel 7i) and may be the projecting ends of the shaft W. This yoke-piece is connected with the bar 19 by a screw 19", whose ends are oppositely threaded. This screw may be turned by the nut 19*, fixed to its middle portion, whereby the length of the brace P may be changed. The other yoke-piece p embraces the gear-case, and its arms 13 form the outer members of ball-bearings for the sleeves 6 6 the cones g being the inner members thereof. The forward end of the yoke 192 is attached by a vertical pivot to the rear end of the bar 1), which form of connection permits the floating of the carriage-body on its springs without causing the binding of the bearings of the opposite ends of the brace P.

The described mechanism permits the two axle members to rotate at different rates,

which is a distinct advantage when the wheel is running on a curve. There are, however, conditions which arise in use wherein it is desirable that said two axle members shall be obliged to rotate in unison. A clutch R is therefore provided for connecting one of the sleeves e or e to the axle member which itembraces. Acommon jaw-clutch is shown, one part 0' being fixed to the sleeve 6 and the other part r movable lengthwise only upon the shaft. The locking of one sleeve to its axle member prevents any independent r0- tation of the two axle members. The ends of the band-brake T, which embrace the periphery e of said gear-case, are pivotally connected with the ends of the two arms t 15, secured to a rock-shaft 6 which is mounted on the rear yokep An operating-arm t is also secured to this rock-shaft, and its outer end is connected by a link 25" with an operatinglever i which is also pivoted on this same yoke. The upper end of this lever is pivotally connected with a draft-rod 25, which extends forward, where itmay be connected by suitable mechanism,whereby it may be moved backward and forward to set or release said brake.

The motor Z, as shown, is a steam-engine, which is supplied with steam from a boiler S through the pipe 5' and past a throttle-val ve U. This throttle-valve is shown in Figs. 5 and 0. It is a hollow casting it, having an internal tapered valve-seat u, upon which the tapered valveU rests. The valve has a downwardly-extended stem 21. by which it may be turned. Two elongated holes a extend down through the top of the valve, their lower ends passing through the tapered wall thereof in a position wherein they will normally be covered by the valve-seat. In the valve-seat are two vertical notches a extending from the bottom to near the top thereof, and when the valve is turned the holes a are brought into alinement with said notches U4 to a greater or less extent, whereby steam may pass from above the valve into the space below in the valve-casing below said valve. On the lower end of the valve-stem is a crank-arm u connected by a link 20 with a crank-arm w on the lower end of the throttle-lever shaft W, which projects up through the body of the vehicle and has at its upper end an operating-lever 20 The position of the link L of the engine is changed by the operation of a rockshaft J, the connection between said rock-shaft and the link being such as is well known. This rock-shaft is operated or prevented from operating by the following novel mechanism: A rock-shaft N is mounted in brackets a, fastened to the vehicle-body A. It has one arm n which is connected by the rod 1?. with an armj on the rock-shaft J. An arm n is also attached to the rock-shaft N, and to the outer end of this arm a handle-bar n is pivoted. A segmental plate 91 which is concentric to the rock-shaft N, is also made fast to the vehicle-body, and it has notches n in its edge, with which a toe a on the handle-bar n is adapted to engage. A spring 72 fastened to the arm n and bearing against said handle-bar n holds said toe n in the notches, but permits the bar to be swung so as to release said toe, whereupon the rockshaft N may be moved, with the result of operating the rocloshaft J, and thereby changing the position of said link.

The throttle-valve and its operating mechanism hereinbefore described is the subjectmatter of another application on file in the Patent Office.
