THOMAS J. PLUNKETT AND WILLIAM SILVERS, OF NASHVILLE, TENNESSEE.

CHAIN-LINK.

Specification of Letters Patent.

Application filed March 3, 1906.

Patented April 14, 1908.

Serial No. 304,149.

To all whom it may concern:

Be it known that we, THOMAS J. PLUNKETT and WILLIAM SILvERs, citizens of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Im rovements in Chain-Links, of which the fol owing is a specification.

This invention appertains to new and useful im rovements in chains, and more articular y to a novel form of detachable ink by means of which two chain sections can be easily and quickly connected or disconnected as may be required. The invention aims to design a link of this character which is simple and inexpensive in its construction and which operates in an effective manner to securely connect two chain sections when in use.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of the detachable link. Fig. 2 is a perspective view showing the tongue swung outwardly in osition for being applied. Fig. 3 is a side e evation showing the link as having two chain sections a plied thereto. Fig. 4 is a top plan view of the detachable link when employed to connect two chain sections.

Corresponding and like arts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the invention the numeral 1 designates the body portion or the stock of the detachable link which is in the form of a loop or flattened ring and corresponds in general shape to the chain rings in common use. A tongue 2 extends across the stock 1, one end of the tongue having a pivotal connection with the corresponding end of the stock while the other end of the tongue has a detachable connection with the opposite end of the stock. For. this purpose an eye 3 loosely receiving an end portion of the stock is formed at one extremity of thetongue while a hook 4 detachably engaging the opposite end portion of the stock is formed at the other extremity of the tongue. Lateral offset portions 5 are located toward opposite end portions of the tongue and operate to throw the body portion of the tongue in a plane spaced from and parallel to that of the stock the offset adjacent the swinging end of the tongue forming one of the sides of the hook. In applying the chain sections 6 and 7 to the link the tongue 2 is swung about its pivotal connection with the stock until the hook 4 is moved out of engagement therewith as indicated in Fig. 2, and the end links of the chain sections being connected are then slipped over the said tongue. Upon the tongue 2 moving back into normal position it will be readily apparent that any tension in the chain will cause the sections 6 and 7 to pull against the offset portions 5 of the tongue and that such action will effectively lock the tongue in position and prevent the hooked portion 4 from becoming accidentally disengaged from the stock.

Having thus'described the invention, what is claimed as new is:

The herein described detachable chain link comprising a loop, and a tongue having the body portion thereof normally disposed in a lane s aced from and a roximatel arllel to that of the loop, ofi s et portions b ing formed in the tongue toward opposite ends thereof and one end of the tongue being provided with an eye loosely receiving the loop, while the opposite end is formed with a hook detachably engaging the loop, the offset at the swinging end of the tongue constituting one of the sides of the hook.
