Specification of Letters Patent.

Application iled June 3,1905. Serial No. 263,572.

To all whom it may concern.-

Be it known that I, PHILLIP H. LETTR, a citizen ot' the United States, residing at Attleboro Falls, in the county ot' Bristol and State of Massachusetts, have invented a new and, useful Improvement in Bracelets,oi` which the following is a specification.

This invention has reference to an improvement in bracelets, and more particularly to an improvement in the construction of the hing'e and catch ot' a bracelet.

The object of my invention is to improve the construction olf bracelets whereby a bracelet is provided with a strong and durable spring-actuated concealed hinge and a practically-concealed catch, the construction ot' which is simpliied and strengthened.

My invention consists in the peculiar and novel construction of a bracelet embodying a spring-actuated concealed hinge and a onepiece catch, whereby the bracelet is opened against the tension ot' the spring, closed automatically, and held in the closed position by the catch, with details of construction, as will be more Vfully set forth hereinafter.

Figure l is a side view of a bracelet embodying' my invention, showing the bracelet in the closed position in full lines and in the open position in broken lines. Fig. 2 is an enlarg'ed detail sectional view looking at the back of the hing'e, showing' the shell ot' the bracelet broken away to clearly show the construction otl the hinge. Fig. 3 is an enlarged detail sectional view looking' at the side ot' the hinge, showing the shell of the bracelet broken away and the hinge in the closed position. Fig. 4 is an enlarged detail sectional view taken on a central line drawn from the outside to the inside of the bracelet, showing the hinge in the open position. Fig. 5 is an enlarged detail sectional view showing the catch holding the ends of the bracelet in the closed position, and Fig. 6 is an enlarged detail sectional view showing the end ot' the bracelet released from the catch.

In the drawings, c indicates one semicircular half, the other semicircular halt', c the spring-actuated concealed hinge, and Z the catch, of my improved bracelet.

The semicircular halves a and Z) are in the form of a tube or hollow shell. The half a has the end a for the hinge c and the end a2, in which is the slot a", for the catch (Z. The

halt' has the end for the hinge and the end Z22, having the inwardly-turned lip 3 for the catch d.

The hinge c consists of a member c', having' the body portion c2, shaped to fit in the end of the bracelet and the forked end c3; a member c", having the body portion c, shaped to [it in the end c ot' the bracelet; the tongue c, adapted to enter the forked end c3, in which it is pivotally secured by the pin o7, forming the pintle of the hinge, and the slot cs, eX- tending' into the end of the body portion c5; a square tube 09, in which is a coiled spring cl", one end of which is secured to the member c in the slot as by the pin cu, and the other endv to the bar cl2, extending across the outer end ot' the tube c". The members d, c", and c of the hinge are all curved to conform to the contour ot' the bracelet, as shown in Fig. 3. The hinge is secured in the bracelet by soldering the body portion c2 of the member c in the end ot' the bracelet and soldering' the cross-bar 012 or the adjacent end ot' the tube c inthe end a/ of the bracelet, with the halves n and of the bracelet in the closed position.

The catch CZ is stamped fron sheet metal, substantially U-shaped, as shown in Fig. 6. The arm (Z/ has the rounded end (Z2, and the arm Z3 has the rounded end d", the notch (Z5, and the outwardly-extending push-teat d, The catch Z is placed in the end a2 of the bracelet in a position for the push-teat d to extend through the slot a in the end a2 and secured by soldering the arm CZ to the inside i of the bracelet.

In the operation ot' my improved bracelet the bracelet is opened by pushing on the pushteat d and forcing' the two halves ofthe bracelet apart against the tension of the coiled spring, as shown in broken lines in Fig'. l and full lines in Fig. 4. The outer edges of the ends a and act as a fulcrum to draw the member c4 and the tube o9 apart against the tension of the spring c1, as shown in Fig'. 4. The bracelet closes automatically by the tension ot' the spring c1", and the ends and be lock automatically by the lip on the end L entering the notch Z5 in the catch d, as shown in Fig. 5.

By this construction I provide a bracelet with a strong' spring-actuated concealed hinge and a one-piece automatic catch, whereby the IOO IOS

bracelet is easily opened and automatically closed and locked in the closed position when released.

It is evident that the sbell of the bracelet could be circular or square in 'cross-section and that the bracelet could have any design or configuration desired without materially aecting the spirit of my invention.

Having thus described my invention, I claimas new and desire to secure by Letters IJatent l. A two-part tubular bracelet having a spring-actuated concealed hinge consisting of a member having a body portion with a forked end, a member having a body portion with a tongue adapted to enter the forked end of the adjacent member in which it is pivotally secured by a pin, a tube, a coiled spring in the tube one end of which is secured to the member having the tongue and the other end secured to a bar crossing the outer end of the tube, a catch stamped substantially U-shaped from sheet metal the arms of which are rounded on the ends, one arm having anotch and a push-teat adapted to extend through a slot in the bracelet, and means for securing the hinge and catch, whereby the bracelet is opened against the tension of the coiled spring without forming a gap or opening in the hingejoint of the bracelet, and closed automatically by the tension of the coiled spring', as described.

2. In a bracelet, the combination with-thehalf a having the end a and the half b having the end of a bracelet, of a spring-actuated concealed hinge 0 consisting of a member c having the body portion c2 with the forked end c3, a member c4 having the body portion c5, the tongue c adapted to enter the forked end o3 in which it is pivotally secured by the pin c7 forming the pintle of the hinge, and the slot c8 extending into the body portion c5, a tube c, a coiled spring 01 in the tube, one end of the spring being secured to the member afin the slot cS by the pin c andthe other end to the bar cl2 extending across the outer end of the tube o, and means for securing `the hinge in the bracelet, as described.

3. In a bracelet, the combination with the half a having the end a', the end a2 in which is the slot a3, and the half having the end b and the end b2 in which is the inwardly-extending lip b3, of a spring-actuated concealed hinge c consisting of a member c having the body portion c2 with the forked end c3, a member c4 having the body portion c5, and the tongue 0G adapted to enter the forked end c3 in which it is pivotally secured by the pin 07 formingthe pintle of the hinge, and the slot 08 extending into the body portion c5, a tube 09, a coiled spring 01 in the tube, one end of the spring being secured to the member 0i in the slot 08 by the pin cu and the other end to the bar 012 extending across the outer end of the tube c, and a U-shaped catch d having' the arm d with the rounded end cl2 and the arm Z3 with the rounded end d4, the notch Z5 and the outwardly-extending push-teat d, means for securing the hinge c in the ends a' and of the bracelet, and means for securing the catch CZ in the end a2 of the bracelet, as described.

1n testimony W hereof I have signed my name to this specification in the presence of two subscribing witnesses.

PHILLIP H. LETTR.
