SWIVEL-HOOK FOR ORNAMENTAL CHAINS.

SPECIFICATION forming part of Letters Batent No. 274,033, dated March 13,. 1883.

V Application filedJauuary 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, CELIUS E. RICHARDS, of North Attleborough, in the county of Bris- 1501 and State of Massachusetts, have invented an Improvement in Swivel-Hooks for Ornamental Chains, ofwhich the following is a specification.

The nature of my invention consistsin a single wire bent to form two opposite hooks, open at one side, and combined with an ornamental sliding band for covering the opening between the ends of the hook.

Figure 1 is a side elevation of the improved swivel-hook open. Fig. 2 is a side elevation of the same closed. tudinal section. Fig. dis a transverseseotion taken in the line a: a: of Fig. 1. Figs. 5 and 6 are detail sections.

In the drawings, Ais the hook, formed of a piece of halt-round wire bent at both ends, thus forming the two opposite hooks, g g, with the open space a between their ends, which space is made of sufficient width to receive the ring of a watch or other article to be attached to the chain. At the bend g of the bent-wire book A is placed the swivel-ring B, which turns on the pivot b, passing through the hub 0 of the swivel-ring. To thecontinuous side of the hook A is a tached the stud d, which enters the groove h of the hollow screw C, covered by Fig. 3 is a central longi;

the ornamental band D, attached to the screw. Thescrew-tubeCDisplacedovertheupperarm of the hook, so that the stud 11 will enter the groove of the screw C, when by turning the tube C D in the proper direction it will be caused to move spirally forward to cover the space a between the ends of the hook. By retbe tube will be moved spirally back, so as to uncover the space a, thus allowing the removal of the ring of the watch or other article i from the hook A.

I prefer to form a notch, e, at the upper end of the screw, into which the stud all will pass, and serve to prevent the screw-sleeve C D from being forced back by direct upward pressare.

Instead of the spiral groove of the screw, a straight groove, f, terminating at a lateral notch, a, may be employed, as shown in Fig. 6.

1 claim as my invention- The combination of the swivel ring and double-ended wire hook, provided with the sleeve-guiding stud, with the grooved sleeve for covering the ends of the hook, substantially as described.

CELIUS E. RICHARDS.
