HENRY S. GOUGHNOU R, OF JOHNSTOWN, PENNSYLVANIA, ASSIGNOR TO THE LORAIN STEEL COMPANY, A CORPORATION OF PENNSYLVANIA.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 717,092, dated December 30, 1902.

Application filed April 9,1901. Serial No. 55,096. (No model.)

To a/ZZ whom, it may concern:

Beit known that I, HENRY S. GOUGHNOUR,

of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Car-Trucks, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

1o My invention has relation to certain new and useful cartrucks, and more particularly to motor-trucks of the single type, and is designed to provide a simple, durable, and easyriding truck.

Itis also designed to provide means of novel and efficient character for taking the end thrusts of the car-body in starting and stopping and which will also act to limit side m0- tion and thrusts.

With these objects in view my invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of a car-truck embodying my invention, and Figs. 2 and 3 are detailviews.

The letter A designates the side frame ofthe truck, which is composed of two parallel edgewise-disposed plates which are supported be- 3o low the journal-boxes B.

O is the sill-plate.

D designates spiral springs which are interposed between the overhanging end portions of the sill-plate and the extended ends of the side frame, and D designates similar springs interposed between the sill and side frames at each side of the journal-boxes. To seat the springs D and D the sill-pieces are provided with the depending spring-seats and cones cl,

4o the latter carrying rods d', which pass vertically through the springs and have a sliding bearing at their lower end portions in the lower spring-seats cl2, which consist of blocks secured between and serving as distance pieces for the edgewise-disposed plates which form the side frame. The latter is supported from the journal-boxes by means of the invetted-U -shaped yokes or straps E,which pass over and embrace the said boxes, forming 5o guides therefor, and whose lower outwardly and horizontally turned portions rest on the top of the side frame and are provided with seats e for spiral springs F; The springs F, one at each side of each of the journal-boxes and between said box and the adjacent spring D', have a top bearing on the under side of caps g, which are carried by vertical rods or bolts G, which pass vertically through the springs, through the seats e, and distancepieces cl2, with heads on their lower ends.

It will be seen that the weight of the carbody when loaded is transmitted from the sill-pieces to the side bars through the medium of the springs D D', and thence to the journal-boxes through the springs F,which are put under downward compression by the load on the side frames. These springs F also act to cushion blows or jars received through the wheels, since any upthrust on the journal-boxes tends to an upward com- 7o pression of said springs.

H designates yokes, which preferably consist of steel castings or forgings and. which are secured to the under side of the sill-plates, one over each of the journal-boxes, with its depending jaws embracing the sides of the box just inside the strap E. The inner edge portions of the jaws are preferably thickened, as indicated at h, to give them a broader bearing against the sides of the4 boxes. These 8o yokes, it will be readily seen, act to prevent independent endwise movement of the carbody and truck and relieve the springs D D from taking the end thrusts due to lurching and sudden starting and stopping of the car. By means of their engagement with the inner sides of the straps E at eachv side of the car they also prevent excessive side motion.

I do not wish to limit myself to the precise construction and combination of parts which 9o I have herein shown and described, as changes may be made in the details thereof without departing from the spirit and scope of my invention.

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

l. In a car-truck, the combination with a sill-plate, and a side frame, supported from and below the journalboxes, and having roo` guides for said boxes, of yokes secured to the sill-plates and engaging said boxes to prevent independent endwise movement of the silll interposed between the sill-plate and side plate and side frame', and also engaging the frames, and the yokes secured to the silljournal-box guides to prevent sidewise moveplates and embracing the journal-boxes.
