UNITED STATES I PATENT OFFICE.

JEREMIAH S. CORBAN, OF PLAINVILLE, CONNECTICUT.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 241,477, dated May 17, 1881.

Application filed March 13, 1880.

To all whom it may concern:

Be it known that I, JEREMIAH S. GORBAN, of Plainville, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Vehicle-Sprin gs, of which the following is a specification.

The object of my invention is to obtain a cheap and yet a stift'spring, which may be used either as a side spring or as end springs, either with or without spring-bars at the sides of the carriage-body. I attain these objects by a single strap or leaf spring bent at one end into a U-shaped form, but with one arm of the U longer than the other, and provided with an eye for convenience of attachment, and the other arm of the U deflected, so as to rest upon thelong arm before described. Sometimes I employ an additional leaf under the shorter one of these arms.

In the accompanying drawings, Figure 1 represents a planview of acarriage-body with side bars and with my improved spring attached. Fig. 2 represents a transverse section of the same on line w m of Fig. 1. Fig. 3 is a side elevation or edge view of one of my improved springs.

When used as end' springs I prefer to arrange them one a little forward of the other, so as to lap by each other in each pair.

A represents each individual spring. The long arm a of the spring has a coil or eye at its end for convenience of attaching it to the side bar, B B, or to whatever object the same may be secured when in use. The shorter arm I) is formed straight on its upper side for a given distance to form a seat to rest against the under side of the body to which the spring is at- (No model.)

tached, the outer end of said arm bein g deflected outward, so as to rest upon the arm a. At the extreme end of this arm b small flanges c are formed, which embrace the arm a and prevent it from slipping edgewise off from the same, while at the same time it is free to slip endwise under pressure.

The springs may be fastened to the body by suitable clips, so that no bolt-holes need be made in them, which will weaken the spring. If greater stiffness is required, an extra leaf may beinserted under the downward-deflectin g portion of the arm I), as designated by letter at in Fig. 2. For a side spring the springs will be secured to the body in the same manner, except that they will extend from front to rear,instead of transversely to the body, and may or may not lap by each other, as represented in Fig. 2.

The advantages of my invention are cheapness of construction, as the springs can be readily formed from a strip of steel by any ordinary blacksmith, and when formed they are of a very sprightly and elastic character.

I claim as my invention The springs A, having one end bent into U form, and with a straight portion for securing the same to a flat seat on a vehicle-body, and

having its other end formed into two springarms, which restone upon the other, and the longer one of which is adapted for attaching that end of the spring, substantially as described, and for the purpose specified.
