DRAFT-SPRING.

SPECIFICATION forming part of Letters Patent No. 474,910,

dated May 17, 1892.

Application filed February 11, 1892. Serial No. 421,123. (No model.)

To all whom it may concern:

Be it known that we, JOHN COLEMAN J OHN* SON and WILLIAM SMITH, citizens of the United States, residing at Drakes Creek, in the county of Madison and State of Arkansas, have invented certain new and useful Improvements in Draft-Springs; and we 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 the letters of reference marked thereon, which form a part of this specification.

Our invention has relation to draft-springs; and it consists inthe novel construction and arrangement of its parts hereinafter set out in this specification and claims hereto attached.

In the accompanying drawings, Figure 1 is a plan View of our draft-spring. Fig. 2 is an edge view of the same, and Fig. 3 is a longitudinal sectional View of the same.

Our spring is made different sizes, so as to be used to the ends of tugs or to single or double trees and may be used to plows, vehicles, or anywhere where draft-power is used.

Our invention is described as follows:

We make a single coil-spring a. \Ve then take a piece of wire I) and bend it into a U shape and pass the loose ends down through the center of said coil andthen bend the ends of said wire back on themselves, forming eyes 1). Te then take another piece of wire 0 and bend it into a U shape, pass the free ends down through the eyes I) and on the outside of said coil and until they are beyond the rear end of the same, and then turn said ends around said wire I), forming eyes 0. Then the front end of said wire 0 is twisted, forming an eye (1. Then the front end of the wire I) is swaged just in front of .the eye a, forming a neck, and around said neck is secured a link e. In the bight of the said wire I) is pivoted a catch f, its free end reaching back far enough to rest against the link e. Between said wireb and said catch f is booked the link end of the hook g, which represents a tug-hook or a chain-link.

It will be observed that the coil-spring a is a piece in itself and not integral with any of the other parts of the invention, and is made of the very best spring-steel.

The pieces I) and 0 pass through each otherthat is, the arms the piece I) and the arms I) pass through the eyes 0 of the arms-and therefore under no circumstances can the spring get out of order unless it is broken.

Having described our invention, what we 6 claim as new, and desire to secure by Letters Patent, is-

1. The combination of the piece of wire 0, having the forward eye 61 and the rear eyes 0, the arms of said wire passing through the spring a, and having the eyes I), and spring a, coiledaround the arms I) and working between the eyes I) and c, substantially as shown and described, purposes set forth.

2. The combination of the piece of wire 0, having the forward eye d and the rear eye 0', the arms of said wire passing through the eyes b, piece 19, passing through the eyes c, through 75 the spring a, and having the eyes 1), spring a, coiled around the arms band working between the eyes I) and 0', link 6, secured around the neck of the piece I), and hook f,

secured in the bight of said piece 1), its free 8:

end working against said link, substantially as shown and described, and for the purposes set forth.

3. The combination of the piece of wire 0, having the forward eye (I c, the'said arms of said wire passing through the eyes 1), piece 1), passing through the eyes 0, through the spring a, and having the eyes 1), spring a, coiled around the arms I) and working between the eyes I) and c',link e, se- 90 cured around theneck of the piece I), hookf, secured in the bight of said piece 1), its free end working against said link, and hook g, secured between said hook and the U end of the wire b, substantially as shown and de- 95 scribed, and for the purposes set forth. 7 In testimony whereof we affix our signatures in presence of two witnesses.
