MEANS FOR GENERATING ELECTRICITY FROM CAR-WHEEL AXLES.

SPECIFICATION forming part of Letters Patent No. 564,336, dated July 21, 1896.

Application filed April 23, 1896.

To all whom it may concern.-

Be it known that I, MORRIS MOSKOWITZ, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Means for Generating Electricity from Oar-Wheel Axles; and I do here by declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has reference to a novel arrangement of a dynamo secured to a cartruck and a means for operatively connecting the dynamo with a car-wheel axle of the truck to drive the dynamo.

The invention therefore has for its primary object to provide a dynamo to be secured on the car-truck, an operating'device arranged and secured upon the car-wheel axle, and a mechanical means, also secured on the cartruck, provided with an operating-shaft arranged in adjustable bearings to automatically maintain the proper tautness of the belt connecting the device on the oar-wheel axle with said mechanical means, and also of the belt which connects said mechanical means with the said dynamo.

The invention therefore consists in the novel arrangements and combinations of parts to be hereinafter fully described, and finally embodied in the clauses of the claim.

The invention is illustrated in the accompanying sheets of drawings, in which Figure 1 is a sectional view of portions of a railway-car and one of its car-trucks, said view also illustrating in side elevation one form of dynamo, a bracket provided with automatically adjustable bearings having a shaft rotatively arranged therein, and a pulley-wheel on said shaft, a pulley-wheel on the car-Wheel axle, and connecting-belts for operating, first, said pulley-wheel on the shaft in the adjustable bearings, and, secondly, the dynamo from a second pulley-wheel on said shaft in the adjustable bearings.

plan view of a portion of the car-truck and of the dynamo and its operating mechanism. Fig. 3 is a vertical section taken on line a; in Fig. 2 when looking in the direction of the arrow at. Fig. lis a perspective view of one of the brackets provided with the herein-' above-mentioned adjustable bearing.

Similar letters of reference are employed in all of the above-described viewsto indicate corresponding parts.

In said drawings, Aindicates the car-truck; a, the equalizing-bars; a, the cross-beams at the ends of the truck, and a are other crossbeams which are connected with the equalizing-bars a in any well-known manner.

As will be seen more especially from Figs. 1 and 2, the dynamo B, which may be of any of the well-known forms of construction, is supported in a suitable frame or bracket a which is secured to the end beam a by means of suitable bolts 00 or in any other suitable manner. The armature-shaft b of said dynamo is supported and rotates in suitable brackets or supports a and aflwhich are secured to the, end beam at of the cartruck, as clearly illustrated in Figs. 2 and 3. Said armature-shaft b is provided with a pulley-wheel b, and b are the circuit-Wires, which extend from the dynamo to suitable lamps b or other electrical translating devices on or in the body of the car.

Upon the car-Wheel axle (t7 I have arranged a pulley-wheel c, which is preferably made in halves and is provided with suitable flanges o and bolts 0 whereby the two halves can be secured together and firmly clamped in the desired position upon the car-wheel axle, as will be clearly evident.

Secured directly to the cross-beam o of the car-truck A are a pair of brackets D, as will be clearly seen from an inspection of Figs. 1, 2, and 4, each bracket consisting, essentially, of a main or body portion cl,having the grooved part d, provided with a hole or perforation d substantially as illustrated in Fig. 4. Extending at a right angle, or approximately so, from the back of said portion d is a lip orprojection (1 provided with a hole 01 whereby said brackets D can be made to embrace the said cross-beam a on two sides and can be firmly secured thereto by means of suitable bolt-s, as clearly represented in Fig. 1, but said bracket D may be otherwise secured to said crossbeams, as will be evident.

At or near the top of the body portion (Z of each bracket D are a pair of lugs or cars 61'', provided with holes or perforations for suitable pins or bolts cl, and pivotally arranged on said pins or bolts cl, and between the said ears or lugs (1", are certain swinging bars or plates c,each plate being provided with a bearin g e, in which is rotatively j ournaled a shaft 6 provided with a pulley-wheel c between said brackets D and a second pulley vheel c at or near the one end of said shaft, substa11- tially as illustrated in said Fig. 2. Said pul' ley-wheel c is in alinement with the pulleywheel 0 upon the car-wheel axle, and a belt e is employed which passes over said pulleywheels and thereby causes the rotation of said shaft 6 when the car-wheel axle is operated. The pulley-wheel e on said sh aft 6 is in alinement with the p ulley-wheel b on the armatureshaft b of the dynamo, a belt 0 being passed over said pulley-wheels, substantially as shown, and thus it will be evident that the dynamo can in this manner be operated from the rotating car-wheel axle.

As will be seen from Figs. 1 and 4, each body portion cl of said brackets D is provided with a forwardly-extendin g arm d having an upwardly-projeeting end piece (Z In order to maintain both of said belts c and e taut, to properly operate the dynamo, I have providcd the upwardly-projecting end piece d and the swinging plates 6 of each bracket D with suitable teats or holding-lugs d and 6 respectively, and upon these I have arranged the ends of a coiled spring 6 substantially as illustrated in said Fig. 4:. hen the belts e and c are first placed over their respective pulley-wheels,then the said springs c are compressed and said swingingv plates or bars 0 made to incline forwardly, which readily enables the placing of the two belts over the respective pulley-wheels, but after both belts have been properly arranged over their pulley-wheels then the said plates or bars c are released and the coils of the spring 6 will then tend to resume their normal inoperative positions, and the result is that both belts will at all times be maintained taut and any vibratory motion of the car-wheel axle in its bearings will be compensated for by the spring'actuated bars or plates 6, whereby an operative connectionfor driving the dynamo, arranged on a car-truck, from a car-wheel axle will be the result.

The operation of the several parts is practical and in construction very simple, and a noiselessly operating mechanism has thus been provided for operating a dynamo from a rotating car-wheel axle. Of course it will be understood that I may use in connection with the said dynamo and its circuits any of the well-known forms and constructions of pole-changers, acting automatically or otherwise, whereby the current generated by the said dynamo can be made to travel in either direction, according to the direction of the travel of the car.

Having thus described my invention, what I claim is 1. The combination, with a car-whcel axle and truck-frame, of a dynamo on said frame, a pulley-wheel on said car -wheel axle, a bracket D on said frame, a swinging bar or plate 6 on said bracket, a shaft a", pulleywheels c and c on said shaft, and belts e and 6 arranged substantially as and for the purposes set forth.

2. The combination, with a car-wheel axle and truck-frame, of a dynamo on said frame, a pulley-wheel 0, made in halves and having flanges c and bolts 0 for securing said halves in position on said car-wheel axle, a bracket D on said frame, a swinging bar or plate 6 on said bracket, a shaft 6 pulley-Wheels e and c on said shaft, and belts c and c, all arranged substantially as and for the purposes set forth.
