MOUNIING FOR ELECTRlC- -CAR MOTORS.

SPECIFICATION forming part of Letters Patent No. 444,922, dated January 20, 1891.

Application filed August 1 5, 1 88 9.

To all whom it may concern.-

Be it known that I, EDWIN WILBUR RICE, Jr., a citizen of the United States, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented a certain new and useful Motor-Suspension for Railwayork, of which the following is a specification.

My invention relates to the manner of mounting or supporting the electric motors employed in connection with railway-cars as a means of propelling the same.

The object of my invention is to secure an unvarying or rigid relation of the parts of the driving mechanism, while'at the same time securing flexibility or adaptation to shocks or vibrations of the vehicle.

My invention consists in the novel construction and combinations of mechanism hereinafter described in connection with the accompanying drawings, and then specified in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a rail Way-car truck having a motor mounted and supported in accordance with my invention. Fig. 2 is a plan of the motor and its supporting devices.

F indicates a frame of any suitable material, consisting of two side pieces and a crosspiece, preferably integral with one another, and having the ends of the side pieces sleeved upon an axle A of the car, which is preferably the drivingaxle. The crosspiece of the frame at the opposite ends of the side pieces F forms a support for one end of the fieldmagnet B.

G C are the polc-pieces of the field magnet, which pole-pieces are provided with exten sions c, of brass or other suitable material, resting on the cross-piece.

The opposite end of the iicld-magnct that is, the yoke end-is sustained by the crosspicces by means of a bar D, which is the yokepiece to which the field-magnet cores are bolt-ed, and is laterally extended, as shown, to permit it to be attached to the side pieces of the frame.

E is the armature of the electric motor, and G is the armature-shaft journaled in the frame F, as shown.

His a shaft of the intermediate gear between the armature-shaft and the car-axle A.

Serial No. 320,906. (No model.)

The shaft H is likewise journaled to the frame, as shown. The caps of the journal-bearings are indicated at I I, &c.

The end of frame F opposite the end which is sleeved upon the car-axle is preferably elastically supported between cushionsor springs S S, carried by a part of the truck-frame K, or by other suitable support.

YVhile I have shown the electric motor as supported byextensions of a bar forming the yoke of the field-magnet, I do not limit myself to this special device, since the yoke end of the magnet might be supported from the frame F by other means without departing from my invention. I prefer to employ the particular manner described 011 account of its simplicity.

It will be seen that the bar D aids in giving rigidity to the frame in which the axes of the armature and core are supported.

\Vhile I have described the frame F as elastically supported from the truck-frame K, I do not limit myself to this particular method of suspension for said frame, since it might be supported from other parts of the vehicle without departing from my invention. I prefer, however, to suspend it from the truckframe. The extension 0 is part of the non-magnetic yoke which unites the ends of the pole-pieces C. The extension 0 may be either applied to the cross-piece I or may rest upon the same, so as to be capable of sliding freely on it. I prefer, however, to fasten it to the cross-piece F, so as to secure increased rigidity.

IVhat I claim as my invention is 1. The combination, with the supporting frame carrying the journal-bearings for the armatu reshaf t, of the yoke-piece for the fieldmagnet extended laterally for attachment to said frame.

2. The combination, substantially as de scribechof a frame F, consisting of side pieces sleeved at one end on the car-axle and a uniting cross-piece at their opposite end, an electric motor having an armature journaled in said side pieces, and a field-magnet supported at its yoke end from ithe side pieces and at its pole end by extensions from said poles resting on the cross-piece.

3. The combination, substantially as described, of a frame consisting of side pieces and a uniting eross-pieee with an electric pieces at one end and having an extension 10 motor having a field-magnet supported atits resting upon and bolted to the cross-piece.
