EDWARD CLIFF, OF NEWARK, NEW JERSEY.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 564,363, dated July 21, 1896. Application filed May 11, 1896. Serial No. 591,006. (No model.)

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, 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.

My invention relates to car-trucks for passenger-cars; and the object is to provide a truck that is simple and durable, and at the same time more easy-riding or capable of carrying a load without undue jarring or jolting.

To this end my invention consists in the combination, with the wheels, axles, and frame, of a bolster formed of a plurality of semielliptic springs extending across the truck between the sides of the frame, cross: bars connecting the sides of the frame, supports between the cross-bars and the ends of the springs, and a plate or beam carrying the center plate or bearing of the truck secured to the centers of the said plurality of springs.

My invention consists also in the combination of the wheels, axles, and side beams, with yielding side bearings between the side beams and held partly below the top sides of said beams; and my invention consists also 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 top plan View of a car-truckembodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged end elevation of the truck-frame, partly in section. Fig. 4 is a top plan view of the portion of the truck at the side bearing; and Figs. 5 and 6 are top and longitudinal sectional views, respectively, of the side bearing removed from the truck-frame,

Referring specifically to the drawings, A A are the axles and wheels,

B B are the axle-boxes.

O C are the pedestals inclosing the boxes,

I and D D are the side beams of the frame,

which are preferably formed of metallic I-beams.

E E are channeled steel end beams joining the side beams together.

F F, &c., are beams running parallel with but between the side beams to support the safety-straps F for the axles, and G G are cross-beams joining the side beams together between the wheels, supporting the inner ends of the beams F F, and also forming the supports for the hangers of the bolster.

The bolster of the truck is formed of a plurality of semielliptic springs H H, the upper parts of full elliptic springs, as shown clearlyin the drawings. These springs are arranged side by side, parallel with each other, and are supported at their ends from the crossbeams G G by means of hangers cl d, mounted on said cross-beams, and links h. The hangers cl consist of plates provided with sockets to receive the ends of a bolt or bar d, preferably in the shape of an axle, so that it cannot move endwise. This bolt or axle extends across between the two bearings, parallel with the side beams D D. The links it for the springs H H are strung upon the bar 61, with short pieces of pipe h between their eyes. The ends of the lower or longest leaf of the spring H is provided with sockets or bearings h h to retain the links.

Only two semielliptic springs are shown forming the bolster, 'butof course any suitable number may be employed. Resting upon the centers of these springs is a plate I, having the center bearing m of the truck.

Another plate I is placed below the centers of the springs, and the two plates are rigidly is formed in two parts which slide one within the other. Such a side bearing, if mounted on the top side of the side beams D, would be too high unless the center plate I was raised. In order to keep the center plate as low as possible and at the same time use these side bearings, I sink the same and support them partly below the top sides of the side beams and on the inside of the latter. Each side bearing is supported in a right-angular saddle f, which is secured at its ends, resting upon the top sides of the cross-beams G G, its central portion being depressed. Ribs j on the sides and bottom of the stationary or lower part of the casing of the side bearing engage the edges of the saddle. The side bearing is also provided with a broad horizontal flange g on one side, which lies on the top side of the side beam D, and is there riveted securely in place.

It will be obvious that my invent-ion does away with the old form of bolster for cartrncks, the sand-planks of wood, and the hangers usually employed, and this without connecting directly the hangers for the bolster with the side beams D D of the truck-frame.

I do not desire to be limited to the precise forms of construction shown herein, as they may be varied without departing from my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a car-truck, the combination with the wheels, axles, and frame, of a bolster formed of a plurality of semielliptic springs extending across the truck between the sides of the frame, cross-bars connecting the sides of the frame, supports between the cross-bars and the ends of the springs, and the center plate secured to the bolster and connecting the springs together, as set forth.

2. In a car-truck, the combination with the wheels, axles, and frame, of abolster formed of a plurality of semielliptic springs extending across the truck between the sides of the frame, cross-bars connecting the sides of the frame together, bars extending between and supported on the crossbars, links connecting the said bars with the ends of the springs, and the center plate secured to the bolster and connecting the springs together, as set forth.

3. In a car-truck, the combination with the wheels, axles, and frame, of abolster formed of a plurality of semielliptic springs extending across the truck between the sides of the frame, cross-bars connecting the sides of the frame together, bearing-plates on the crossbars, axles on the bearing-plates extending between the cross-bars, links mounted on the axles and forming hangers for the ends of the springs, and the center plate secured to the centers of the springs, as set forth.

4. In a car-truck, the combination of the wheels, axles, side beams and cross-bars, saddles between the side beams and extending between the cross-bars, the end portions of the-saddles lying on the upper sides of the cross-bars and the central portions of said saddles lying below the top sides of the side beams, and yielding side bearin gs containing coiled springs supported on said saddles, as set forth. 7

5. In a car-truck, the combination of the signed my name.
