VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 328,238, dated October 13, 1885.

Application filed July 12, 1884. Serial No. 137,570. (No model.)

To all whom it may concern:

Be it known that I, THOMAS J. MAGNEE, a citizen of the United States, residing at ellsville, in the county of Allegany and State of New York, have invented certain new and useful Improvements in Vehicle-Springs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a perspective view of the under side of the spring. Fig. 2 is a bot tom view. Fig. 3 is an end view of a vehicle, showing the springs attached.

This invention has relation to vehiclesprings; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

The object of the invention is to provide a simple and strong spring for use between the bolster and axle or between the body and sidebar of a vehicle.

The spring consist-s,essentially, of twin spiral portions extending horizontally and terminating at their inner ends in short contiguous arms adapted to be attached to the body or bolster, and at their outer ends in longer arms extending obliquely toward each other and terminating in bearings or eyes,whereby con-- nection is made to shackles or other connecting devices of the axle or side-bar.

In the accompanying drawings, the letters A A designate the branches of the spring. Each branch consists of a horizontal spiral portion, B, the inner end of which is extended in the form of an arm, 0, which is designed to be secured to the bolster or body of the vehicle by a clip-plate or other common fastening, as indicated at G. Usually the arms 0 O of the two branches are set to abut against each other throughout their length, so that they mutually aid in sustaining the inward thrust to which each arm 0 is subjected when the spring is under strain. The outer ends of the spiral portions B are extended to form free or movable arms D, which are longer than the fixed arms 0. These long arms are formed with a graceful curvature, and are directed obliquely toward each other, their terminal ends being joined together. The end v will serve for both.

In making these springs the spiral portions B B are curved from end to end, so that the entire spiral portion of the spring will have a graceful arc shape, and in order that the long arms D will extend truly from the end whirls of the spirals in the oblique direction in which they are designed to run.

I am aware that it is not new, to form a vehicle-spring with two spiral branches having an intermediate crank portion for the attachment of a pivoted lever which connects .with the side-bars, and each spiral having a parallel arm for connecting with the body of a vehicle.

I am also aware that it is not new to form a spring with two spiral portions having contiguous arms connecting with the sidebars of a vehicle and outer parallel arms connecting with the body thereof, the arms connecting with the side-bar being curved and the arms connected with the body provided with a clip, and therefore do not claim such devices, broadly.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A vehicle-spring composed of the spiral portions extending horizontally in arc shape, the attachment arms extending from the inner ends of the spiral portions, and the oblique arms extending from the outer ends of said spiral portions, substantially as specified.

2. The vehicle spring consisting of the spiral portions 13, having their inner ends terminating in short engaging parallel arms and their outer ends obliquely directed towards each other and clipped together, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS J. MAGNER.
