IMPEROVEMENT IN LAP-RINGS.

Specification forming part of Letters Patent No. 219,465, dated September 9, 18%9; application filed May 22, 1879.

To all whom it may concern:

Be it known that I, ELI HANGOX, of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Lap-Ring, of which the following is a specifi cation.

In the accompanying drawings, Figure 1 represents a top view of my improved lapring; Fig. 2, a top view of a detached section of the same. Fig. 3 is an end view; and Figs. 4 and 5 are vertically-transverse sections of the lap-ring, respectively on lines 00 m and y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

This invention relates to a strong and reliable construction of lap-rings for chains of all kinds; and it consists of diagonally overlapping and interlocking riug-sections, that are connected by a central transverse stay, secured bya fastening-screw, and, in addition thereto, by cross-pinsor rivets.

Referring to the drawings, A represents the sections of my improved lap-ring, which are made of equal size and shape, as shown in Fig. 2, with recesses or openings a at one side, with diagonally cut and overlapping end partitions, b, and with solid middle portions, d, that are of equal size with the open parts.

Therin g-sections overlap at their diagonallycut ends and interlock with each other, as the solid middle portions of the sections fit into the open parts of the same.

The solid middle portions of the ring-sections are strengthened by a transverse center stay, B, that is fitted by its concaved ends to the convex solid portions of the sections A, and rigidly secured thereto by a metallic screw,

0, that passes through the solid part of one section and the stay into a screw-socket of the solid portion of the other ring-section.

The rigid stay B strengthens the lap-ring, and locks also the overlapping and interlocking sections firmly and reliably together.

I11 addition to the stay may be used taperin g pins or rivets 6, that connect the overlapping portions of the ring-sections, and which are secured when the lap-ring is applied for use by spreading the thinner ends. These fastening-pins are especially useful for larger sizes of rings or shackles, as they furnish, in connection with the stay and screw, a strong and reliable lap-rin g.

I am aware that it is not new to make a large boss on the center of a lap-ring; but this could not be used with the Emerson windlass generally used onships; also, that tongues have been forged on the halves of the link together with notches and sockets; but these require in the manufacture dies and drophammers of accurate adjustment. My link, being made of round iron and the two halves secured together by rivets, is almost as strong and durable as a solid link, is adapted to the Emerson Windlass, and is withal so simple that it may be made on shipboard withthe ordinary ship-tools.

What I claim as new and of my invention is- A lap-ring provided with the cross-bar having concave ends, and held in place by screw, substantially as shown and described.

ELI HANGOX.
