CAR-TRUCK.

SPECIFICATION forming partof Letters Iatent No. 562,579, dated J une 23, 1896.

Application filed March 12, 1896.

To all whom it may concern:

Be it known that I, EDWARD CLIFF, of Newark, in the county of Essex, in the State of New Jersey,l1ave invented new and useful Improvements in Oar-Trucks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to car-trucks, and more particularly to street-car or motor trucks, and the objects are to provide an improved construction of not only the truckframe and its springs, but also of the brakerigging.

To this end my invention consists in the combination, with the wheels, axles, and axleboxes, of the side frames, each made in two parts, pedestals and struts connecting the two parts rigidly together, springs between the axle-boxes and the pedestals, and a semielliptic spring bearing with its center upon the lower side of an axle-b0x and havingits ends supported by the frame.

My invention consists, further, in the combination, with the axles and wheels, of a brake-shoe made in two parts, said parts being pivoted together at their center, and a spring between the parts on each side of the pivot; and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a side elevation of a car-truck embodying my invention. Fig. 2 is an enlarged detail view of a portion of the brake beam and shoe. Fig. 3 is a top plan view of my improved car-truck, and Fig. 4: is a cross-sectional view taken on line 0000 of Fig. 3 and looking from right to left.

Referring specifically to the drawings, A A are the wheels, B B the axles, and B B the axle-boxes.

. O is the lower portion of the side frame, and O is the upper portion thereof. The upper portion or piece is adapted to support the body of the car, and the lower portion or piece extends, with its central portion approximately on the lineof the axles when in its normal position, parallel with the upper frame directly above it, the ends of said lower frame being bent or inclined upward to meet extend to the upper frame and are there bolted or riveted. Between the upper side of the box 13 and the lower side of the pedestal c is a coiled spring d to aid in supporting the frame upon the axle. The two parts of the frame, or, in other words, the upper and lower frames, are separated and rigidly joined together on each side of the truck by four struts e e e c, with bolts passing through them and the frames. The struts e e are out side of the axles and support the ends 'of cross-bars D D, extending between the sides of the frame. The struts e e are between the axles and support the ends of two central cross bars E E, which not only support the brake-rigging, but the motors (not shown) of the truck.

To aid the coiled springs d cl,&c. ,in supporting the frame upon the axle-boxes, I provide a semielliptic spring F below each axle-box, the center of the spring lying in a socket f, formed on the lower side of the box. A bolt f passes through the socket below the spring. The spring is preferably the lower half of an elliptic spring without eyes at the ends. The ends of the springs F are straight and fit in. sockets g g, which are bolted and riveted to the lower side of the frame.

It will be apparent that the above-described construction makes a very durable and easyriding truck.

Referring to the brake-rigging, H is the brake-beam; I,.the loop-hangers to retain the beam in its proper position; it, castings secured to the brake-beam to guide the latter in the hangers; 2", the brake-beam head, which is square and fits into one of the members of the brake-shoe J, J being the second member of the shoe, which is pivoted to the other member by a bolt j and bears upon the tread of the wheel A.

The brake-beam ll extends between the two shoes bearing upon the inner treads of the wheels A A. Said brake-beam has square ends, which extend into the members J J of the shoes, said members being each divided vertically and provided with bolts 76 70, so that they may be adjusted to make up for wear upon the shoe. In other words, the bolts 7c may be loosened and the shoe moved toward:

or from the tread of the Wheel. The brakeshoe being divided into two parts J and J, and swiveled or hinged together at the center by the bolt j, allows the part bearing on the wheel to rock to perfectly adapt itself to the wheel. Coil-springs H are held in sockets in the part J on opposite sides of the boltj and bear upon the part J to steady it and prevent rattling.

K K are cross-bars extending between and secured rigidly to the brake-beams 1-1 H on opposite sides of the truck. lever between the bars K K, and pivoted to them at the center. lever L are connected by chains to pulleys G G above, said pulleys being fulcrumed in brackets h Z1, extending between and secured to the cross-bars E E. Each pulley is double, 1

having a larger part to which the chain m,

connected to the draw-bar m, is attached The draw-bars lead to opposite ends of the truck, where they are provided with suitable and wellknown means for operating them. The operation of either draw-bar will revolve a pulley and raise both brake-beams to apply the brake-shoes to the treads of the wheels,

shoes will drop away from the wheels.
