CAR-SP RING.

SPECIFICATION forming part of Letters Patent No. 364,286, dated June "7, 1887.

Application filed October 4, 1886.

To all whom, it may concern:

Beit known that 1, WILLIAM C. PERRY, of Charlestown, in the county of Vashington and State of Rhode Island, have invented certain new and useful Improvements in Gar-Springs, of which the following` is a specification, reference being had to the accompanying drawings, making part hereof.

This invention is an improvement in car springs and trucks, the object being to secure great elasticity with simplicity and cheapncss of construction. In some of its features my present improvement resembles another invention in vehicle-springs, for which my application for patent is tiled simultaneously herewith.

The features peculiar to this invention are a series of elliptic or equivalent springs on the truck supporting a fnlcrum-bar, in combination with a series of crossed levers pivoted centrally or otherwise on said bar and con4 nected at their ends to the truck-frame and car-frame by yielding connections.

My invention consists in the combinations of devices hereinafter described, and especially referred to in the appended claims.

In the accompanying drawings, Figure l is a plan of part of a car-truck provided with my improved springs. Fig. 2 is a section thcreofon the line m x, Fig. l. Fig. 3 is an end elevation of a similar construction.

A represents the frame of the truck, which will be o f any suitable construction, and provided with wheels, axles, bearing-boxes, dre., in the usual way. rIhese parts are not herein Serial No. 215,329. (No model.)

serves as a fulcrum for the crossed and pivoted levers D, which at their ends are united to the truck-frame and the car-body by suitable yielding connections, so that when the springs are compressed and the levers de pressed by the weight in the car-body the ends of the levers may move outwardly to a proportionate extent.

NVith the arrangement shown in Figs. l and 2, the fulcrum-bar rests on and is secured to a clip, E, surrounding thelcavcs ofthe spring. The lower ends of the lever D have a longitudinal movement on elongated staples F, while their upper ends are shown slotted to receive pins, thus permitting suitable yielding at each end.

In Fig. 3 swinging links Gr connect the levers, respectively, to the frame A. and the base II of the car-body, the clip E serving to sus pend the bar C within the springs B-that is, below the upper member ofthe several springs. These two forms are regarded as equivalents, and lnay be substituted one for the other.

Having thus described my improvements in car-springs, I claim as my inventionl. The truck-frame A,supporting the series of springs B, in combination with the bar C, and the pivoted levers D, fulcrumed on said bar .and joined to the frame and car-body by suitable yielding connections, substantially as set forth.

2. The combination of a series of elliptic springs with a series of crossed levers fulcrumed on a bar supported by said springs and connected thereto by clips E, embracing the leaves of the springs, substantially as set forth.
