JOHN P. MORRIS, OF WALTON, TEXAS.

LAP-RING.

SPECIFICATION forming part of Letters Patent No. 238,143, dated February 22, 1881.

Application filed September 24, 1880.

T 0 all whom it may concern:

Be it known that I, JOHN P. MORRIS, a citizen of the United States, resident at Walton, in the county of Van Zandt and State of Texas, have inven ted certain new and useful Improvements in Lap-Rings; and I do hereby 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 letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in lap-rings; and it consists in the peculiar construction and arrangement of the several parts, as hereinafter fully explained, and specifically pointed out in the claim.

In the drawings, Figure l is a side view, partly in section. Fig. 2 is an edge view, and Figs. 3 and 4 are detail views, of a ring constructed after my iiwention.

a is the main bar, which has both ends bent over and brought near together in the same plane, as shown, so as to leave a suflicient space in which to place the connecting-bar b. The turned-over end a of the ring" a is furnished with a vertical mortise, (0 in which is placed the tenon b of bar I), which is held on a suitable pin, b so that it turns readily, as The turned-over'end a of the bar I) is provided with a T-shaped mortise, a, which is adapted to receive the T-shaped head If, formed on the end of the hinged connectingbar I). V

c is a spring-catch placed in the T-mortise m, where it is held by a suitable screw or bolt. This catch may be made of an elastic bar, which will spring outward of itself, or it may be a stiff bar pressed outward by a spring, a, placed in a recess in the end of the ring a. The upper end of the catch 0 is provided with arear lip, 0 which slides into a suitable recess in the ring a, and prevents dirt and other (ModeL) substances from getting between the catch-bar and the end of the ring. The lower end of the catch-bar is suitably covered by a lip'on the end of the ring a, as shown. This ring is made oval or oblong in shape, so that it will always adjust itself and bring the draft on the hooked v ends a and entirely clear of the connectingbar b.

My ring cannot be drawn out of shape when sustaining a heavy draft. The T-head b fits snugly into the T-mortise a, and the two parts interlock and effectually prevent any opening or widening of the space filled by the bar I).

In ordinary rings the locking devices are "often rendered entirely useless by reason of the stretching of the ring and the consequent drawing apart of disconnected ends. This defeet is completely overcome by my method of interlocking the ends of the connecting parts, as hereinbefore described.

It will be seen that when the T-head is in place in the T-mortise no lateral bending of the bar I) can take place. The sides of the mortise a serve as jaws to hold the end of the bar I), and thereby entirely relieve the catch 0 from strain and liability to injury.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, with the ring 0., having the mortise a and T-mortise a, of the bar I), furnished with a tenon, b, and T-head b and the spring-catch 0, provided with the rear lip, 0 and secured in the inner end of the T-mortise a, all arranged to operate substantially as and for the purposes set forth.
