SPECIFICATION 'forming part of Letters Patent l'lo. "793,874, dated Cl'uly a, 1905.

Application liled March 16, 1905. Serial No. 250,343.

lie it known that l, ALEXANDER EKLUN'D, a citizen of the United States, residing at Attleboro, in the county of Bristol and State oi' Massachusetts, have invented certain new and useiul llrnprovements in Separable Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

Alvly invention relates to separable fasteners i'or bracelets, and is particularly adapted to such bracelets as have concealed joints. lts purposes are to provide a fastening whose actuating means shall be largely concealed and a fastening whose release will involve an impulse to throw the engaged parts asunder, also a structure which shall be durable with a minimum number oi' parts.

lli/ly invention resides in the peculiar structure and combination of parts herein deeribed, and illustrated in the accompanying drawings.

Figure Il is a plan view of a concealed-joint bracelet embodying my invention; Fig. 2,'a vertical longitudinal section ol the portion of the bracelet containing the catch mechanism in engaged position; Fig. 3, a similar section of the same disengaged; Fig. 4i, a section on line .r c' oi' Fig. 3; Fig. 5, a section on line 1/ f/ of Fig. 3; Fig. 6, an end elevation oiI one oi" the bracelet-wings, and Figs. 7 and Fl side and plan detail views of the plunger.

Like reference characters indicate like parts throughout the views.

lin the drawings, A and B represent the hollow sections or wings of a jointed bracelet. Pivoted on a transverse pin a, shown as supported in a block ai, is a latch 7) with an upwardly-directed hook or head Z/ upon its free end. The extremity oit the head is inclined or pointed b2. The end of the wing Bis provided with an opening c, adapted to receive lthe head of the latch when the parts are engaged. Mounted in the wing B in the rear of the opening c is a block (Z, surrounded by a sleeve d and supporting a `iiat spring ff, with a slightly downwardly curved extremity e. This spring-extremity e is adapted to guide the latch-head into engagement with the shoulder f, lornned by the opening c in the wing` B, and the spring e by its tension retains the head in engaged position. This shoulder forms a keeper for the latch.

Mounted. in the upper part of block Z so loosely as to allow vertical movement is a plunger G. '.llhe body (j thereof is curved to conform to the curvature of the bracelet-section and rests loosely in a cut-out portion of the block (Z and is supported by the latter. The headv y of the plunger extends slightly below the plane of the body, and upon the upper portion oi the plunger-head is an integral projeetion ya, whose upper face lies substantially in the plane oi' the exterior of the braceletn wings, whose ends are semicircularly pierced, as shown at z, in Fig. l, to allow a passage or seat for said projection, said projection having one or more depressions g, as seen best in lFig. il, to be engaged by the linger-nail.

lo disengage the catch, the wearer downwardly presses with the thumb or linger nail the projection y, thereby forcing the latchhead il downwardly against the tension oi the spring' e, which, yielding', trees the head from the shoulder f and forces the wings apart.

lflaving described my invention, what l claim I l. ln a bracelet, a catch ior the ends ot its jointed sections thereof, the same comprising a latch pivotally mounted within one end oit one section, a spring within the adjacent end of the other section, a keeper for the latch, and a curved plunger in the section with the spring, the said latch being receivable between the said spring and plunger, as and for the purpose speci'lied.

2. ln a bracelet, a catch for the ends ol its sections, the same comprising a block within the hollow end oi one section, a spring carried by said block, a plunger guided in said block, and a block in the other section at its adjacent end, and a latch pivotally mounted in said block and receivable in an opening in the end of the companion section.

The combination with the hollow bracelet-sections, oi a block in one end of one section, a spring mounted therein, a plunger.'
