MEANS FOR SUSPENDING MOTORS ON VEHICLES.

SPECIFICATION forming part of Letters Patent No. 603,927, dated May 10, 1 898 7 Application filed February 25,1898. Serial No. 671,548- (No model.)

To all whom it may concern:

Be it known that I, SIDNEY H. SHORT, a citizen of the United States, residing at Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements in Means for Suspending Motors on Vehicles, of which the following is a full, clear, and exact description.

My invention relates, broadly, to that class of apparatus used for the propulsion of wheeled vehicles, whether such apparatus employ steam or electricity as its motive power, and partioularlyto that class of apparatus of which a motor having electricity as its motive power forms a part. 7

My invention has for its object to produce a new and improved apparatus which shall be more simple and effective than that heretofore used,wherein the motor shall be springcushioned, where necessary, without being springsupported from the truck or car body. I do this because it has been found that such an arrangement as that last named, however advantageous, nevertheless permits an unnecessary movement of the motor and causes too great a jumping tendency and a variance in and uncertainty as to the amount of clearance between the motor and the road-bed.

Figure l is a perspective View of an apparatus embodying my invention. Fig. 2 is a plan view of the same, only such parts of the truck being shown as are necessary to explain Fig. 3 is a view showing the various features in a diagrammatic side elevation. Fig. 4 is a detail view of a bearing, and Fig. 5 is a modification of the same.

Referring to the drawings, M represents the driven axle of avehicle, N N two Wheels, and T the truck-frame or car-body, all of which may be of any desired or well-known construction.

The part lettered A is the motor frame or casing. In the present instance an electric motor is shown, and the frame A is the fieldmagnet of the motor, constituting an inclosing casing within which are arranged the four poles 1910 19 19. This casing is divided on the horizontal line B and has trunnions O O, which, as shown, extend from the neutral or yoke portion of the field-magnet, as distinguished from the pole-pieces, and encircle the shaft D of the armature E. These trunnions are themselves surrounded by the bearings F F in the ends of the arms G G of a yoke or alinement-frame H. These features are all substantially the same as are shown and described in my Patent No. 546,560, dated September 17, 1895. From the casing A extend two projections I I, which are supported by the cross-piece h of the alinementframe H, springs J J being interposed.

Springs J 2 J together with the bolts R R, limit any upward thrust. The side of the casing A remote from the axle is supported by being directly connected to a cross-bar K, which is preferably set on edge, so as to better prevent any upward or downward yielding or movement at the point of support. This thus does away with all spring support from the body of the vehicle or truck and its accompanying uncertainty of position or, as it has been termed, floating. This cross-bar K, as will be seen in the drawings, is supported from the truck-frame or car-body by bearings L L, mounted thereon, in which the crossbar can have a slight movement of rotation. The bearings L L may be circular, as shown in Fig. 4, or, if desired, a slight play may be permitted by making them slightly elongated, as shown in Fig. 5. The connection between the cross-bar and the motor is preferably effected by means of a projection from the upper half of the motor, securely fastened to the cross-bar, as shown. It will thus be seen that while the distance between the armatureshaft and the axle M of the driven wheels N N is maintained constant there is no flexible or spring connection between the motor and the car-body or truck-frame, resulting in uncertainty of position or too great movement, and that the motor is still cushioned as to the driven axle by the springs J J, which come between the projections and the cross-piece h of the yoke. The arms of the alinementframe in no way support the motor, but on the contrary are supported by it, their whole function being to preserve the proper dis tance between the two axes of revolution.

While I have shown the motor as attached to the truck-frame at the end away from the axle, it is obvious that I can attach it to the car-body without departing from my invention.

The truck-frame is of the ordinary construction and may or may not be mounted upon springs W in the ordinary way.

What I claim is 1. The combination with a wheeled vehicle of an alinement-frame mounted on a driven axle, a motor journaled in the arms thereof, the weight of the motor being partially borne by springs interposed between the same and said alinement-frame, and by a rigid support extending to the truck-frame and inelastically supported thereby, substantially as described.

2. The combination with a wheeled vehicle,

of an alinement-frame mounted on a driven axle, a motor journaled therein having projections, and partially supported by springs interposed between said projections and said frame, and a rigid support connecting said motor with the truck-frame, substantially as described.

3. The combination with a wheeled vehicle of an alinement-frame mountedon the driven axle, an electric motor journaled in the arms of said frame, projections from the field-magnet of said motor engaging with springs bearing on said alinement-frame, and a rigid support for the part of the motor remote from said projections, substantially as described.

4:. The combination with a wheeled vehicle of an alinement-frame, a motor journaled therein and free to turn relatively thereto, springs interposed between a portion of said motor and said frame, a rigid cross-bar to which the upper part of said motor is directly connected, substantially as described.

5. The combination with a wheeled vehicle of an alinement-frame, a motor journaled therein, springs between a portion of said motor and said frame, a cross-bar to which the upper portion of said motor is rigidly connected, and bearings in which said'cross-bar is mounted, so as to be free to turn, substantially as described.

Signed at the city of New York this 23d day of February, 1898.
