UNITED STATES PATENT OFFICE.

SHUBAEL GOTTLE, OF NEW YORK, N. Y.

BRACELET.

SPECIFICATION forming part of Letters Patent No. 243,218, dated June 21, 1881.

Application filed May i, 1881. (No model.)

Figure 1 is a perspective view of the bracelet, showing in dotted lines its opened position. Fig. 2 is a longitudinal section through the swivel'joint. Fig. 3is a detail view of the pintle-tube. Fig. 4 is a cross-section through the line 00 a: of Fig. 2. Fig. 5 shows detail views, in perspective, of the thimbles.

My invention relates to an improved form of bracelet of that general construction in which several tubular parts with swiveling joints are combined with a torsional spring arranged within the same, whose tension serves to hold the sections of the bracelet in an elliptical form, but allows them to be opened by a lateral movement for the insertion of the wrist. 2 My improvement consists in making the bracelet in two hollow sections with their terminals and swivel-joints both in the minor axis of the ellipse, and combining them with a torsional spring within, and also in'the peculiar 0 form of swivel -joint, as will be hereinafter more fully described.

In the drawings, A A represent the two sections of my bracelet, which are made hollow and connected by a single swivel-joint at a, so

This swiveljoint to, and also the gate or separable joint formed by the lapping terminals of the bracelet, lie diametrically opposite each other in the minor axis of the ellipse. Within this brace- 0 let and extending through both hollow sections is an elliptical spring, B, whose tension causes the two sections to normally occupy the form of an ellipse, but which permits the two lapped ends of the sections to be opened away 5 from each other laterally, as showinin dotted lines in Fig.1, to permit the introduction or removal of the wrist.

To connect the adjacent ends of the sections to form the swivel -joint, I fix in the adjacent 5o ends of said tubular sections straight thimbles O O, which have transverse slots 00. (See Fig. 5.) These thimbles are suitably stayed and secured in the curved ends of the tubes, so as to have a common axial relation, and the adjacent edges of the tubes and thimbles are suitably faced to form bearingsurfaces.

Extending through both of the thimbles O O is a straight pintle-tube, D. This pintletube has, at its opposite ends, and preferably upon opposite sides, projecting lugs d d, which enter the slots 0 c of the thimbles and prevent the two sections of the bracelet from moving apart. These lugs I preferably form by stamping in the tube tongues e, and then turning up the ends of the same'to form the lugs, as shown in Fig. 3. The tubular character of the pintle D, it will be seen, gives passage to the torsion-spring B; and its lugs 61 d, in addition to their function of holding the braceletsections together, act as stops to limit the amount of lateral deflection between the two parts A A of the bracelet. Thus, when the two ends of the bracelet are turned away from each other, the lugs d d traverse the slots 0 0 until they reach the end of the same, when they act as stops to prevent further movement.

In defining my invention more clearly I would state that I am aware that a bracelet has heretofore been constructed of a semi-elliptical tube and two quadrantal pieces made hollow and combined with an inner torsional spring. My invention is distinctive with respect to this in the following respects First, I have but; one common axis for the movable sections of my bracelets, which makes the latter simpler and stronger; and, secondly, this swivel-joint being located at the minor axis of the ellipse, it is removed from contact with the more or less angular bones of the wrist, and it cannot therefore pinch the wearer in putting it on or off, and if an ornamental head or edging should be made at this joint it does not interfere withthe comfort of the wearer, as it would it located at the smaller parts of the wrist or in the line of the major axis of the ellipse.

Having thus described my invention, what I claim as new is- 1. An elliptical bracelet composed of two hollow sections connected together by a swiveljoint located in the minor axis of the ellipse, and a torsional spring located inside the bracelet and extending through both sections, all sional spring D, passing through said tubular 10 combined substantially as and for the purpose pintle, substantially as and for the purpose dedescribed. scribed.
