CHAIN LINK.

Application filed November 4, 1921.

Fig. 1 is a plan, partly in section, of one form of our improved chain link; Fig. 2 is an elevation thereof; Fig. 3 is an elevation similar to Fig. 2 but with the detachable member of the link in the position in which it is applied to the link; Figs. 4 and 5 show the main portion of the link in elevation and plan, respectively; Figs. 6 and 7 show the detachable portion of the link in plan and elevation, respectively; Fig. 8 is a plan of a modified form of our invention; Fig. 9 is an elevation thereof; Fig. 10 isa section on lines X-X oi Fig. 8; Fig. 11 is a plan, partly in section, of a further modification of our invention; Fig. 12 is an elevation thereol': Figs113 and 14 are sections on lines XIII XIII and XIV+XIV, respectively. of Fig. 11; and Fig. 15 is a side elevation of the detachable member.

Our invention relates to links for anchor cables and comprises a separable link or shackle which may be employed to repair a broken anchor chain, replace a defective link, or to connect together the shots of chain which make up a length of cable. Our invention also comprises the various features which we shall hereinafter described and claim.

Referring to the drawings, A indicates the main body ot the link, B the T-shaped separable member, and C a rivet, pin or bolt for securing the member B in the link body A. The link A has a seat or depression 2 on the transverse axis of the link, and opposite this depression 2 is an opening 3 clear through the other side of the link, and the ends of the link terminate in similarly formed arms 4 in each of which is a groove 5 formed by arcs struck from the transverse axis of the link A as a center. The grooves 5 have under-cut

sides

6 and 7 which form lugs 8 and 9 toward the outer side of the link.

The T-shaped member B has at the bottom of its le 10 a projection 11 which fits into the recess 2. The leg 10 forms the stud of the link, and the arms12 of the T fill in the open side of the link. The leg 10 has arcshaped shoulders 13 extending in the direction of the horizontal axis of the link, which form bearings against the interior side faces of the link A and serve to holdthe piece B in position and also to stiffen the link A. The member B has on the inner faces of its Serial No. 512,756.

arms 12 circular projections 14 struck on radii from the axis of the member B, which corresponds to the transverse axis of the link. The projections 14 have

lateral extensions

15 and 16 to engage the

undercut portions

6 and 7 of the grooves 5. \Vhere it is desired to connect two links in the ends of lengths of chain the link A is threaded through the free eyes of such links, the three links are pulled out straight and the Tmember B is inserted through the open side 3 of the link with its long dimension at right angles to the body of the link, as is shown in Fig. The projection 11 is seated in the recess 2 andthe piece B is then rotated through 90 about its axis, thus causing the shoulders 13 to engage the inner side faces of the linkand the projections 14 to enter into the grooves 5 on the arms 4 of the link. In this position the

lateral extensions

15 and 16 of the projections 14 will engage and form an interlock with the

undercut sides

6 and 7 of the grooves 5. riotation of the member B after it is in the position shown in Figs. 1 and 2 is prevented by the rivet or pin C, which may be inserted into the counter-sunk aperture 17 and when inserted has a bearing against the end of anarm 4. 1

hen themember B is in the position just described the interlocking of the parts prevents them from spreading or pulling apart.

Thus the projections 14 with their

extensions

15 and 16 hold the arms 4 from spread- B firmly against movement along the transverse axis of the link and also support the link A against collapse.

In Figs. 8, 9 and 10 we have shown a modifled form of our invention in which the T- member B is applied from the side of the link. In this form the lower end of the leg of the T is in the form of a. hook 21 which engages the inner face of a lug 22 comprising part of the projection 23which forms a base for the stud. The T-shaped member B is applied in a direction perpen-- dicular to a plane lying in the horizontal axis of the link, sothat the projections 24 on the arms of the member B are brought into engagement with the hooks 25, and the hook 21 engages the lug 22.

When the member B is in position it is held against outward movement by the hook 21, which engages la 22 and by the reentrant angles of hoo {

S

24 and 25, which also prevent spreading of the arms of the link A. Sidewise movement is prevented b the rivet or pin C, which is inserted through the registering

apertures

26 and 27 in the leg of the member B and in the projection 23.

In Figs. 11 to 15, inclusive, the T-member is inserted along the transverse axis of the link A. The ends of the arms of the link A have a U-shaped recess 31 and terminate in a flange 32 beyond the recess. The arms of the T-member B terminate in a U-shaped projection 33 which fits into the U-shaped recess 31 and engages the flange 32. The leg of the T is circular in cross section and the lower end seats in a depression 34 in the link A, in which it is held by a taper pin C which seats in registering apertures in the link A and in the lower end of the leg. One end of the aperture 36 in the link A is counter sunk for the reception of a soft metal collar or washer 37, which is pressed in this counter-sunk portion, filling it and a groove 38 in the pin C. Mounted on the leg of the T-shaped member B is a spacing member 39 which holds the parts of the link against collapse and also tends to hold the parts rigidly together.

We have found that links constructed in accordance with our invention may be manufactured commercially because of their simple construction at low cost and when used have been found to be comparable in strength and durability with links cast in one piece.

The terms and expressions which we have employed are used as terms of description and not of limitation, and we have no intention, in the use of such terms and expressions of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are possible within the scope of the invention claimed.

What we claim is: 1. A chain link comprising a member having an open side terminating in arms extending toward each other, a closure member en- I said 0 osure member having a projection and recess enga ement with said arms near the ends thereo arranged to prevent the spread ing of said arms, said closure member having a stem comprising the stud of the link, the said steam seating and being secured in a recess in the inner face of the closed side,

and securing means engaging the said members and preventing relative movement thereof, the link when the said members are secured together forming a rigid link with identically shaped and symmetrical surfaces.

3. In stud links for anchor chains, a link having an open side terminating in arms extending toward each other, said arms having arc-shaped grooves, a member mounted in the transverse axis of the link having projections arranged to interlock in said grooves on rotation of the said member, and means for securing the members against relative movement.

4. In stud links for anchor chains, a link having an open side and a T-shaped memher, the leg of the T-shaped member comprising the stud of the link and having a bearing in a recess on the closed side of the link, the T-shaped member having projections interlocking with projections on the arms of the link and also carrying shoulders engaging inner side faces of the link.
