CHAIN-LINK.

SPECIFICATION forming part of` Letters Patent No. 688,735, dated December 10, 1901. Application filed October 27, 1900. Serial No. 34,576. (No model.)

T0 all whom, it may concern:

Be it known that I, LOUIS C. HOWE, of Indianapolis, Marion' county, Indiana, have invented a new and useful Improvement in Chain-Links, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l show s in plan View a chain-link constructed in accordance with my invention. Fig. 2 is a vertical section on the line II II of Fig. l, and Fig. 3 is an elevation of the detachable block which closes the transverse opening of the link.

In the drawings, 2 represents the link, the body portion of which may be of any convenient form. One of its end bars 3 is formed with a concave inner side, as shown in section in Fig. 2, and the other end bar l,which is of greater diameter, is hollow, the cavity extending from side to side of the link and havingatransverse opening which is adapted to be closed by a detachable block 5. The cavity in the end bar 4 is adapted to receive the end bar 3 of an adjacent link, which is inserted from the side of the link in a direction lengthwise of the end bar. The end bar 3 and the block 5 are inserted simultaneously, the block 5 being placed between the side bars of the second link and in contact with its end bar 3 before joining the two links together. When theA parts are thus assembled, a tongue h on the inner face of the block 5 abuts against the concave surface of the end bar 3 and forms a pivotal ridge on which the links are articulated. It is important that the block 5 be held firmly and permanently in place in the opening of the end bar 4t, for if it should become loose it might in some cases cause the chain to part. For the purpose of fastening it I form on the inner portion of the block 5 one or more notches or sockets c, and on the end bar etat points directly opposite to the position of these notches I reduce the metal in thickness so as to form easily-compressible portions d d. When the parts are assembled, as shown in Fig. 2, I compress the portions d d with a suitable tool and force the metal into the sockets o c, thus attaching the parts together in a secureand permanent manner.

It will be understood that, if desired, the notches may be made in the end bar and the compressible portions on the block.

The advantages of my invention are that it affords a strong and durable link, and the attachment of the block in the link is effected without substantially increasing the cost.

l. An open link havinga transverse opening in one of its end bars, and a detachable block extending into the opening, one of said parts having notches or sockets and the other part having a portion or portions reduced in thickness and adapted to'be compressed into said notches or sockets; substantially as described.'

2. An open link having a transverse opening in one of its end bars, and a detachable block extending through the opening, said block having notches or sockets, and the end bar having portions reduced in thickness, and adapted to be compressed into said notches or sockets; substantially as described.

In testimony whereof I have hereunto set my hand.

L. C. HOWE.
