ELECTRlCALLY-DRIVEN CAR.

SPECIFICATION forming part of Letters Patent No. 387,610, dated August '7, 1888.

Application filed July 1), 1887.

To all whom it may concern.-

Be it known that I, Josuru' \Vms, of Jersey City, New Jersey, have invented certain Improvements in .l llectrieally-I)riven Cars, of which the following is a specification.

These improvements, which are applicable to cars driven by an electric motor, irrespeet ive of the source from which the current to operate the motor is supplied, relate generally to a motor-supporting frame carried directly upon the axles of the driving-wheels; a main earframe supported on springs,whieh in their turn are supported upon laterally-movable boxes in which the axles of the drivingwheels are respectively journaled; a motor for rotating a COUIltOPSlliLliJ provided at one or both ends with a suitable spur or friction wheel or wheels adapted to respectively engage the driving-wheels; stationary brakes arranged in the vertical planes of the drivingwheels, respectively; manually operative starting and stopping apparatus, embracing means for moving the driving-wheels at each side of the car toward each other and thereby bringing them into engagement with the said spur-wheel or spur-wheels, or for moving the driving wheels away from each other and thereby disengaging them from the said spur wheel or wheels, and bringing their peripheries into contact with the said stationary brakes.

.l n the accompanying drawings the improvements are shown as applied, first, to a com paratively small car supported upon the driving-wheels, and in which provision is made for operating the stopping and starting mechanism from one end of the car only, and, secondly, to a larger car provided at both ends with means for operating the stopping and starting mechanism.

The drawings are as follows: Figure 1 is a side elevation of the driving-wheels of a small car and one of the floor-girders of the car, showing the manner of supporting the same upon the laterally-:uljuslable boxes in which the driving-wheels arcjournaled. Fig. 2 is a longitudinal vertical section of the small car illustrated in Fig. 1, showing in elevation the motor-supporting frame and the manuallyoperative lever system for moving the drivingwheels toward or away from each other. Figs. 3 and 1 illustrate the application of the improvements to a larger ear provided at Serial No. 241,707.

(No model.)

both ends with means for manually operating the stopping and starting mechanism. Fig. 3 is a top View showing the side floor-girders and the motor-frame carried directly upon the axles of the drivingwheels and the axle of two ear-supporting wheels. Fig. 4 is a longitudinal vertical section taken through the line at :r on Fig. 3, showing the lever system for operating the stopping and starting mechanism from either end of the car.

No attempt is madein the drawings to show the body of the car, it being deemedsuffieient to show the longitudinal girders upon which the body of the ear is erected. These girders A A may be taken to indicate the floor and platforms of the car. They are providedwith the usual downwardly-projeeting box-frames, A, for containing, respectively, the boxes B l &c., in which the axles (J (l of the drivingwheels I) and the axle C of the car-supporting wheels 1) are respectively journaled.

Springs E E, &e., bear, respectively, at their upper ends against the girders A A and at their lower ends against the plates 0 e, 850., resting upon the tops of the boxes B B, &e., respectively. The boxes are made suliiciently narrow, as shown in Fig. 1, to give them the required range of movement in the box-frames. The motor'frame F is carried directly upon the axles of the driving and car-supporting wheels by means of boxes (l G, &c., in which the axles of the driving-wheels arejournaled, and which are adapted to slide to and fro between the uppcr and lower horizontal members of the side trusses, f f, of the motorframe. Two stationary brakes, H II, project downward from the girde' A on each side of the car in position to impinge upon the peripheries of the driving-wheels when the latter are moved away from each other.

The driving-wheels are preferably each provided with a laterally projecting annular flange, d, and When the driving-wheels are forced toward each other their faces, or the faces of their flanges d, as the case may be, are pressed against the peripheries of the frictionwheels I I, mounted upon the opposite ends, respectively, of the transverse counter-shaft I, journaled in boxes affixed to the motorsupporting frame. The counter-shaft I is rotated by power derived from an electric motor, .K, preferably transmitted through slowing-down gear, in order that the motor may be rotated at high speed.

It is not deemed necessary to show or de scribe the motor in detail, as the construction of electric motors is well uinlerslmnl, and be cause it is immaterial what form of motor is employed, so long as its capacity is sul'tieient to al'tord the power required for driving the car.

As electric motors ordinarily operate with greater clllcicncy when they are allowed to rotate with great rapidity, the motor shalt K is provided at one or both ends with a small spur-wheel or spur-wheels, 7;, respectively, for engaging the larger pinion or pinions, i i, at"- fixcd to the counter-shalt l. The drivingwheels are moved toward and from each other by means of lever systems arranged, respectivcly, on the outer sides of the motor-frame. As the two lever systen s on theopposite sides are alike, a description of one will answer as a description of the other. As shown in Figs. 2 and 4, the sliding boxes G (l are connected, respectively, by' the pitmen 5 with pivots inserted, respectively, above and below the axis of the rocker L, which is pivotally al fixed to the side truss of the motor-frame.

In the organization shown in Fig. 2, in which the stopping and starting mechanism is capable of operation l'rom one end of the car only, one end of the rocker L is connected by means of the pitman l with the crank-pin m of the crank-arm m, allixed to the llilllS\(!SO rock shaft M, which is mounted in fixed hearings in the end of the motor-frame.

A crank-arm, N, at'lixed to and projecting upwardly from the rock-shaft M, is provided with a radial recess, N,whieh serves a. a socket for the reception of the end of the stopping and starting bar 0, which, when inserted in the recess N, projects upward through a suitable opening in the platform.

In the organization shown in Fig. 1 means are provided for operating the stopping and starting mechanism from both ends of the car. In this case, it necessary by reason of the length of the car, the two additional wheels, d, are provided, the axle of which is journaled in non-adjustable boxes carried in frames al'lixed to and projecting downward from the girders in the ordinary manner; and similarly the. mo tor-frame may he supported near One end upon boxes G, which are permanently al'lixed to the side trusses of the motor-frame.

To operate the stopping and starting mechanism from either end of the car, both ends are provided with rock-shafts linked to the rocker L, as illustrated in Fig. 4, in which, as will be seen, while the lower end of the rocker L is connected by means of the pitman L, t\"e., with the rock-shaft M at one end of the car, the upper end of the rocker L is comieeted, by means of the pitman Z with the rock'shal't M at the opposite end of the car.

One object in connecting the roekshatts M. and M, lOSlJGCtlVOl), with opposite ends of the rocker L is to prevent contusion in operatin the starting and stopping bar 0 at the opposite ends ol' the car.

It will be pertaived t :at the arrangement is such that when the bar 0, having been inserted in its socket at either end of the car, is pushed outwardly therel'rom, the drivingwheels are moved toward each other and carried into engagement with lrictionwheels I; and similarly, when the hand lever 0, having been inserted in its socket at either end of the ear, is pulled inwardly, the driving-wheels are separated from each other, disengaged from the lricl ionwheels, and carried against the stationary brakes ll.

ll. will be perceived that the motor and the lever system for throwing the driving-wheels of the car into or out of contact with the spur-wheel or friction-wheel, which delivers the power from the motor or into or out of contact with the brakes, as the case may be, are mounted upon a frame (the motor-frame F) which is supported directly upon the axles of the car-wheels, and is thus wholly inde pendent of the platform or body ol the car. As the plat term or body of the car is carried by means of springs in the usual manner on the outer ends 01' the axles of the car-wheels, its movements up or down are not communicated to the motor-l'rmne; hence the lever system is prevented from being-rocked outot position by the jolling movements of the carbody.

\.\'hat is claimed as the invention is--- l. In an electrically-drivcn car, a motorsupporting l'rame mounted directly upon the axles of the car-wheehl or drivingwhcels and carrying a manually-operative lever system, in combination with ear-wheels or drivingwheels having their axles imlrnaled in later ally-movable lmxes, tor the purpose of enabling the said wheels to be moved by means of said mannally-opcrative lever system into or out of engagement with the spunwhecl or trio tion wh ieh transmits l'rom the motor the power to rotate the said earwheels or driving-wheels.

2. in an electrically-driven car, two pairs of driving-wheels having their axlesjournaled in lateiai ly-movable boxes,and stationary brakes arranged in llievtatieal planes of the drivingwheels, as shown, in combination with a manually-operalive lever system for moving the said pairs of drivingwheels away from or toward each other, and thereby forcing their faces into or out of contactwil h said stationary brakes.

3. In an. elect rically-d riven car, two pairs of d riving-wheels havi ng theiraxlcs journaled in laterally movable lJflXOFhiHltl an electrically-rotatable shalt carrying at or non r its ends spurwheels or frictionwheels, which are respectively interposed between the driving-wheels, in combination with stationary brakes arranged in the vertical planes ol' the drivingwheels, as shown, and a manuallyoperative lever system for moving the said pairs of driv ing-wheels away from or toward each other, as and for the 1n|rposes set forth.

4. A ear-body carried. by means of springs 5. The driving-wheel D, provided with the IO upon driving-wheel axles journaled in laterlaterally-projeeting annular flange (l, in comally-movable boxes, in combination with a lvination with the electrically-rotatable frio motor-supporting frameindependently mounttioirwheels l, substantially as set forth. ed upon the driving-wheel axles, and having affixed upon it a manually-operative lever sys- JOHN H tem for moving the driving-wheels toward or away from each other, as and for the purpose set forth.
