SPECIFICATION forming part of Letters Patent N 782,188, dated February '7, 1905.

Application filed September 23, 1904. Serial No. 225,601.

'/'o r/// [rho/2t it Duty concern: f

Be it known that 1, JOHN BENNETT, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bracelets, of which the following is a specification, reference being had therein to the accompanying drawings.

.\l,v invention relates to bracelets and similar articles constructed upon the lazy-tongs principle. Such articles have heretofore proved practically deficient, particularly because of the lack of proper expansive and retractive means and because of the multiplicity of constituent parts, besides other structural defects.

To the end of overcoming the above deficiencies my invention primarily consists in the novel construction and combination of parts hereinafter described, and illustrated in the accompanying drawings, wherein Figure l is a side elevation of a bracelet embodying my invention, showing the parts retracted; Fig. 2, a similar elevation of a section of the same, indicating the parts in expanded position; Fig. 3, a plan View of the latter. and Fig. 4, a transverse vertical section on line .1 .r of Fig. 1.

Like re't'erence-letters indicate like parts throughout the views.

Referring to the drawings, the bracelet comprises an endless chain consisting of a series of upright parallel arms 1/, to each of whose backs and near whose center is pivoted similar arms 6. The extremities of both arms of each arm couplet are connected by pivot-pins r with the ends of adjacent pairs of arms, thus producing a lazy-tongs structure. Intermediate each pair of arms are mounted the retractile means, consisting of a tubular member l). comprising the two telescoping sections 1/ (1'. These sections are provided upon their outer ends with flat lugs C and c, respectively, which are pierced at u 0 to receive the pivotpins c, by which means the sections of the tubular member I) are maintained up- 4 rightl; in their relative intermediate position. i

Traversing the interior of tube 1) is a spiral spring .5.

The action of my improved bracelet is as fol lows: .Tn expanding the same to apply to the wrist the parts assume the position shown in Fig. 2. which results in a compression of the sections 1/ 1! against the tension of the inclosed spring s. hen the bracelet reaches the wrist and the manual expansion thereol is discontinued, the upward force 01 the spring a contracts the parts to the relative positions shown in Fig. 1.

It will be noticed that in my novel bracelet each set of four crossed arms has its retracting means, which assures the bracelet snugly encompassing the wrist; also, that the coiled springs constituting the retracting means are entirely inclosed at all times by the tubular telescoping sections (1 J, and hence are not liableto get out of order or be atl'ected by perspiration. It will further be noticed that in virtue of the sections (I 1 having flat lugs interposed between and pivoted to the crossed arms the said sections and crossed arms lie in the same plane, Figs. 3 and 4:, and the necessity of making the braceletumluly thick'and heavy is obviated.

Having described my lIlVOIitlOH, what I claim is- A lazy-tongs bracelet comprising crossed arms pivoted together and to adjacent arms and having their ends lapped with those of said adjacent arms, and retractile means complementary to each set of four arms; the said means being made up of tubular telescoping sections lying in the same plane as the crossed arms and having flat lugs at their ends interposed betwecn and pivoted to the lapped ends of the arms, and coiled springs entirely incloscd in the said sections and tending to press the same endwise outwardly.

In testimon ywhereof I have atlixed mysignature in presence of two witnesses.

JOHN BENNE'IT.
