WALTER S. ADAMS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE J. G. BRILL 00., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
CAR-TRUCK.
Application filed March 30, 1914.
To aZZ whom it may concern:
Be it known that I, \VALTER S. ADAMS, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Car-Trucks, of which the following is a specification.
The object of my invention is to provide a suitable pivoted car truck for surface cars or other cars, as may be desired, in which the frame is provided with two upwardly arched semi-elliptic springs, and each spring is surmounted by a coiled spring on top of which is a cap from which are suspended suitable links that extend below the arch of the semi-elliptic spring, and the links on opposite sides of the truck are united by means of a suitable bolster, from which the car body may be supported in the conventional way.
For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure l is a side elevation of a truck provided with my improvement. Fig. 2 is a sectional view, taken on the line 22 of Fig. 1, looking in the direction of the arrows. Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2, looking in the direction of the arrows.
Throughout the various views of the drawings, similar reference characters designate similar parts.
My improved truck 1 has the usual side frames 2, pedestals 3, wheels 4 and axles 5, all of which may be of the usual construction. It also has the usual transom 6 and tie-bars 7 which may be of any suitable form. The pedestals 3 are each provided with suitable seats 8 which support the ends of the upwardly arched semi-elliptic springs 9 so that these ends may move longitudinally of the truck, but not transversely. Each spring 9 has a suitable band 10 at or about its center, and on top of this is a. suitable seat- 11, which carries a coiled spring 12, and this spring is surmounted by a suitable cap 13 which has side seats formed by the lugs 14 and these seats carry suitable hangers 15 which extend below the level of the band 10 and are united at their lower ends Specification of Letters Patent.
Patented Dec. 8, 1914.
Serial No. 829,138.
-rub-plates '21 which are preferably fixed thereto and adapted to engage corresponding plates fixed to the transoms 6 of the frame 2 by means of suitable bolts, 01' other wise.
From the foregoing description it will be observed that the weight of the car body is borne by the bolster through the side and center bearings and from thence is carried to the connection 16 and from them through the hangers 15 to the cap 13 and then down on the coiled spring 12 to the straps 10 through the lower spring seat 11 and from thence along each end of each spring 9 to the frame 2 of the truck. By this construction all shocks and .jolts incidental to the use of the truck will be transmitted to the car body, if at all, through two sets of springs, a set of leaf springs and a set of coiled springs, so that the bolster of each truck is carried with a freedom from all violent jars and jolts.
While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures which come within the scope of the annexed claim.
Having thus described my invention, what I claim is:
In a truck of the class described, side frames, an upwardly arched spring carried by each side frame, a coiled spring carried by each leaf spring and mounted on top of the same, caps on said coiled springs, hangers carried by said caps extending on each sideof said leaf springs, connections between said hangers, and a bolster carried by said I connections.
