T0 at whom it may concern:

Be it known that we, MORRIS Mosxowrrz and SAMUEL YOUNG, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain newand useful Improvements in Mechanism for Transmitting Power from a Car- Wheel Axle to a Dynamo within the Car; and

we do hereby 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.

Our present invention relates to novel features in mechanism for driving a dynamo from a car-wheel axle when the car is in transit.

Many methods have been devised for electricallylighting railway cars,in some of which the power for driving the dynamo has been taken directly from the rotating car-wheel axle,but in these constructions and arrangements of the mechanical means for transmitting the power from the axle, as heretofore used, serious obstacles have been encountered.

The invention therefore consists essentially in the arrangement of a supplemental shaft, which is preferably a spring-supported shaft, connected by means of a link chain with the car-wheel axle, said shaft and axle having suitable sprocket wheels on which the chain runs, a countershaft on thebottom of the car having a sprocket Wheel, and a link chain connecting said countershaft with the springsupported shaft on the car truck, and an intermediately arranged mechanism for driving the dynamo, and maintaining a uniform speed of the dynamo.

The invention further consists of certain other arrangements and combinations of parts such as will be hereinafter more fully described and finally embodied in the clauses of the claims.

The invention is illustrated in the accompanying sheets of drawings, in which- Figure 1 is a part elevation and part sec tion of a railway car, with its truck, illustrating the arrangement of the mechanism on the truck and in the car for driving the dynamo,

and an electric lighting system leading therefrom and comprising thereinthe lamps and storage batteries. Fig. 2 is a cross-section on an enlarged scale of one end of a railwaycar, illustrating in elevation theseveral pieces of mechanism embodied in this invention, and connected with a speed-regulating device for maintaining a uniform speed of the governor. Fig. 3 is a plan view of the car-truck, showing the arrangement thereon, of a spring-supported shaft, and the sprocket wheels thereon and on the car-wheel axle, and a link chain or chains for communicating the rotary motion of the car wheel axle to said spring-actuated axle and therefrom to the mechanism within the car. Fig. 4c is a detail View of one of the spring-supported bearings in which the supplementary shaft used in connection with the car-truck is supported, said shaft being represented in cross-section, and Fig. 5 is a horizontal section of the same, taken on line 55 in said Fig. 4.

In the above described views, A indicates a railway car and a one of the car-wheel axles. Said axle a rotates in the usual boxes or spring supported bearings a of the car-wheel truck, and in any convenient position on said axle a is secured a suitable sprocket wheel a Directly behind the pivotal support of the truck is arranged in suitable bearings O, a spring-supported shaft 1), provided directly behind said pivotal support and in line with the longitudinal axis of the truck, with a sprocket wheel b To one side of this wheel I) and on the axle b is a second sprocket wheel I) which is connected with the sprocket wheel a on the car-wheel axle a by the link chain a Said sprocket wheel 12 is connected by means of a link chain cl with a sprocket wheel d arranged on a shaft (1 revolving in suitable beariugs d secured to the frame-work of the bottom of the car, as will be clearly seen from Figs. 1 and 2. Of course it will be clearly evident, that during the motion of the car, the normal distance between the central axis of the car-wheel axle a and the bottom of the car A, will become greater or less according to the motion of the car and the unevenness too of the road-bed." Thus, if the shaft 1) were arranged torotate in fixed bearings,the chain belt 01 might become sufficiently strained to cause it to snap, or said chain at other times would hang loose and become disconnected from the sprockets of the wheel b In order to maintain, at all times, no matter how much the relative positions of the truck and car-body may vary, a normal strain on the chain at and to keep the same sufficiently taut and in contact with the sprocket wheels I) andd, said shaft 12 rotates in the spring-supported bearings O secured to the frame of the truck, as shown in Figs. 1 and 2. Said bearings, consist of suitable frames 0, and the members 0' and c of each journal box are adapted to slide on the guides c of the frame 0. The two members 0' and c of each journal box are suitably connected and secured around the shaft 1) by straps c and screws or bolts 0 and the lower ends of said guides o of the frame are connected by means of a connecting plate or bar 0.

As will be seen from Fig. 4, a spring a" is arranged above the member a between the same and the' upper portion of the frame 0, the normal pressure of which constantly causes the journal box and hence the shaft 1) to be forced downwardly, thereby keeping the link chain d sufficientlytaut, and preventing the displacement of its links from the sprocket wheel 12 no matter how great the variation between the relative positions of the truck and the car body. A second spring c ,which may be of a slightly weaker capacity than the spring 0 is arranged between the member a and the connecting plate or bar 0,which acts as a cushion and to a certain extent counteracts the compressive force of the spring 0 to prevent the chain 61 beingpulled too taut around its sprocket wheels. As has been stated in the above, the shaft 01 rotates in its fixed bearings d and therefore the sprocket wheel 61 revolves in the same position, and owing to the arrangement and construction of the spring-supported members 0' and c of each journal box, the sprocket wheel I) will be forced downwardly by the action of the spring 0 upon the shaft b, thereby taking up any un. due slack on the chain 61 and at the same time removing all extra strain or pull on the chain, as willbe clearly evident. Of course, it will be understood, that the link chain a which moves horizontally, or approximately so, has sufficient slack to overcome the variation in the heights of the car axle a and the shaft 12, to obviate the difficulty of the chain being thrown off or disengaged from the sprockets of the wheels a and b.

In order to prevent any undue twist of the link chain 01, connecting the wheel 19 on the spring-supported shaftb and the wheel 01 on the shaft d it is very essential that said parts are arranged as near the pivotal support of the car truck, as is possible. The two bearings O for supporting the shaft 1) are also placed as closely together as possible, as will be seen from Fig. 3, and both of said wheels b and 01 must be arranged in a vertical plane which passes through the longitudinal central axis of the truck. When the sprocket wheels 5 and d are thus arranged, any swinging movement of the truck in making curves, will throw the wheels 5 and cl out of center verylittle, and not enough to effect the movementof the link chain (1 or to twist the same. As will be seen from said Figs. 1 and 2, said shaft 61 is provided with a second sprocket wheel (1 from which extends a link chain 61 to a sprocket wheel 6' arranged on a shaft 6, substantially as illustrated, for driving an intermediately arranged mechanism, which operates the dynamo and regulates the speed thereof. The general arrangement of said mechanism for finally operating the dynamo is illustrated in Figs. 1 and 2, which is deemed sufficient for a clear understanding of the case. The speed-regulatin g device, illustrated in said Figs. 1 and 2, which may be of any suitable construction, is connected with said shaft eby means of a suitable reversing clutch, which acts automatically, as the car moves backward or forward to cause said speedregulating mechanism to rotate at all times in the same direction. Said speed-regulating mechanism is connected by means of a belt 7" with the armature shaft 8' of any suitable dynamo s, as will be seen from Fig. 2. From said dynamo extend the circuit wires 5 and s which lead to a series of storage batteries 15, which are preferablyarranged in a suitable box T, underneath the car, as will be seen from Figs. 1 and 2, but said batteries may be placed in any suitable part of the car. From said batteries 25, extend the light circuit wires t and t in which are arranged any suitable number of lamps F. In said circuit we may place a switch 25 for closing off the current from the batteries.

\Vhen the dynamo is started, by the action of the car-wheel axle, and the intermediately arranged starting and speed-regulating mechanism, the electrical current can be made to pass directly through the circuit wires t and t to the lamps i or the current can be made to pass directly into the storage batteries, which is preferable, for in this manner a con.- tinuous current of electricity can be obtained to feed thelights to cause them to burn uniformly, during the variations of speed of the train, or while waiting at stations, &c.

We do not wish to be understood as limiting ourselves to the exact arrangements and constructions of the several parts of mechan ism comprised herein, for certain changes may be made Without departing from the scope of our present invention. The several forms of mechanism herein shown and claimed which are embodied in one complete machine is of a simple construction and owing to its compactness can be suitably arranged in any desirable portion within the car, preferably IIO comprising therein, a sprocket wheel a aspring-supported shaft b, a sprocket wheel I) on said shaft, a link chain connecting said sprocket wheels, a sprocket wheel h on said shaft 19, a shaft (1 on the car-body,asprocket wheel (1 thereon and a link chain connecting said Wheels cl and b and means connecting said shaft d with the dynamo, substantially as and for the purposes set forth.

2. In the herein described means fortransmitting power from a car-Wheel axle, the combination with the car-body, its supporting truck and a car-wheel axle, of a dynamo within the car and means for driving said dynamo, comprising therein a sprocket wheel a a spring-supported shaft 1), a sprocket wheel I) on said shaft, a link chain connecting said sprocket wheels, a sprocket wheel b on said shaft b, a shaft (1 on the car-body, a sprocket wheel 01' thereon and a link chain connecting said wheels (1 and 11 a sprocket wheel (1 on said shaft 01*, a shaft 6 and a sprocket wheel 6' and link chain at connecting said wheel d and e for driving the dynamo, substantially as and for the purposes set forth.

3. In the herein described means for transmitting power from a car wheel axle, the combination, with the car-body, its supporting truck and the car-wheel axle, of a dynamo within the car-body, an automatically adj ustable shaft b on the car-wheel truck, and means connecting said shaft 19 with the car-wheel axle, for causing the rotation of said shaft b, and means connecting said shaft with the dynamo, consisting essentially of a sprocket wheel I) on said shaft 1), a shaft d secured to the car-body, a sprocket wheel d thereon and a link chain d connecting said sprocket wheels I) and d, and means connecting said shaft 01 with the dynamo for operating the same, substantially as and for the purposes set forth.
