EDGAR PECKIIAM, OF KINGSTON, NEI/V YORK, ASSIGNOR, BY MESNE ASSIGN- `MENTS, TO THE PECKHAM lMOTOR TRUCK AND WHEEL COMPANY, OF

SAME PLACE.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No.' 464,253, dated December 1, 1891.

Application lled October 30, 189Q. Serial No. 369,787. (No model.)

To all whom it may concern.-

Beit known that I, EDGAR PECKHAM, lof Kingston, inthe county of Ulster, in the State of NewYork, have invented new and useful Improvements in Car-Trucks,of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the trucks of electric cars carrying the motor on the trucks.

The chief object otl the invention is to provide the truck with a motor support or hanger which shall permit the armature to be readily removed through either the top vor bottom of the truck, and also allow the motor sufficient lateral play to avoid cramping the same when the car is traversing a curve in the road.

The object of this invention, also, is to utilv ize the coupling-bolts of the car-springs for staying the car-body laterally, so as to prevent its shifting from its requisite position over the truck.

To that end the invention consists in the improved construction and combination of parts hereinafter fully described, and spe cically set forth in the claims.

In the annexed drawings, Figure lis a side elevation of a car-truck embodying my improvements. Fig. 2 is a vertical transverse section on line a: oc, Fig. 1 Fig. 3 shows enlarged vertical transverse section ot' the niotor-hanger. Fig. 4 is an enlarged vertical transverse section of one of the car-springs with the lateral stay of the car-body, and Fig. 5 is a top plan view of the truck.

Similar letters of reference indicate corresponding parts. y

A A represent the car-wheels fixed to their axles A A', which are journaled in the boxes C C in the usual and well-known manner.

` Upon the boxes C C are hung the yokes a o.,

`nally over the truck.

tached longitudinal bars B B which extend nearly or rquite to the ends of the car and have the life-guard R attached to them and extending beyond the end of the car-body. The said bars B and B are braced by a longitudinal truss-bar D, secured to the lower ends of the inner limbs of the yokes ct a, and end braces D D extending upward from the lower endsv of the outer limbs of the yokes and attachedl to the bars B B some distance from the yokes. Straps D D extend across the lower ends of the yokes and are connected thereto and to the adjacent portions of the truss bars and braces D D by means of bolts which are removable to allow the journal-boxes to be removed downward from the truck-frame when desired. The car-body is supported on ,the side bars B B andBB bysprings b b. To stay the body both laterally and longitudinally over" the truck and at the same time retain the springs b b vertically on the truck, I rigidly attach either to the car-sill or to the longitudinal top bars I I depending posts c c, which-pass through caps d, springs b, and base-plates f of said springs, and are allowed to slide vertically in the same, as shown in Fig. 4 of the drawings. The said base-plates being firmly attached to the bars B B serve to guide the posts c c vertically and prevent the car-body from shifting either laterally or longitudi- The caps ol of the springs being usually thin plates,I form with downwardly-extending tubular bosses d',

which receive the posts c c through them, as shown in Fig. 4 ot the drawings. Said tubular bosses serve as guides for said -posts and for the caps. The free ends ofthe bars B B I provide with additional supports by connecting said portion of the bars to the carbody by means of spring-hangers U.

In order to obviate obstructions to mounting on the Ytruck a car-body having crossbeams secured to the under side of its end portions, and to also afford ample room to accommodate a rheostat when desired to be applied to the truck, I-dispense with the crossbars, which are usually attached to the ends of the side bars of the truck-frame,`and in lieu of said end cross-bars I tie the two sides of the truck-frame together by means of crossbars m m, secured to the lngitudinal top beams I I of the truck near the wheels A A, as best seen in Fig. 5 of the drawings.

Between the journal-boxes on each side of the truck I mount on the bars B B one or two pedestals P P, according to the number of motors to be connected to the truck. Said pedestals, rising from the side bars B B, are inserted between the bars B B and preferably supported thereon by shoulders g on the pedestals riding on top of one of the bars B. By means of bolts h, passing transversely through the said bars and intervening portions of the pedestals, the latter are retained in position. Each of the pedestalsP isformed with a downward extension P the lower end of which is bifurcated and embraces thereby the lower longitudinal truss-bar D, as shown more particularly in Fig. 3 of the drawings.

The upper end of the pedestal is formed with a horizontal offset P extending inward some distance beyond the inner bar B, and this offset has an eyet extending vertically through it. Through thiseye passes the shank of a bolt j', which is secured in a suspended position by nuts n n and washers o 0, connected to the bolt above and below the offset P.

To the lower ends of the two bolts jj, at opposite sides of the truck, are pivotally connected two parallel cross-bars F F, and to said cross-bars, at a point about midway between the bolts jj, is secured the motor-support Il. In order to allow this support to rock laterally, I make the eye t' sufficiently larger than the bolt to allow the latter to move laterally and interpose between the offset P and washers 0 o soft-rubber cushions t t, and by surrounding the portion of the bolt which is in the eye t' with a rubber tube or lining t the motorhanger becomes insulated from the truckframe. The motor-support II may be of any suitable construction, according to the style of motor employed. My preferred form of the motor-support consists of the prop L, which is mounted on the cross-bars F F and is rigid and formed with a downwardly-projecting tenon u, which passes between the cross-bars and is bolted or riveted thereto. Over the top of the aforesaid prop is the heel N ot' the motor. Between this heel and top of theV prop is interposed a soft-rubber cushion t), and a similar cushion is placed upon the heel N. Vertically through the two cushions and intervening heel and through the prop L is a bolt-hole for the reception of the bolt fu',

which is provided with nuts and washers w at both ends. may be inserted between the bottom of the cross-bars F and subjacent washer w. By means of the aforesaid nuts the heel of the motor is securely retained on its support. The aforesaid cushions serve to relieve the motor from the severe jars incident to the vertical thrust of the heel of the motor when starting said motor. By placing on the portion of the If desired, another cushion n bolt t" which is within the heel N a bushing of rubber or other non-conducting material the motor becomes insulated from its support II.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent, is v l. In an electric-motor truck, the combination, with longitudinal side bars supported on the journal-boxes, of pedestals mounted on said side bars and rising from the same, crossbars suspended from said pedestals, and a motor-support mounted on said crossbars, asset forth.

3. In combination with the longitudinal side bars supported on the journal-boxes, pedestals mounted on said side bars and formed with inward offsets, bolts suspended from said offsets and oscillatory laterally in their connection, cross-bars pivotally connected to said bolts, and a motor-support on said cross-bars, as set forth.

4. In combination with the side bars B B and truss-bar D, the pedestal P, secured to said side bar and formed with the downward extension P', connected to the truss-bar, substantially as set forth and shown.
