Specification of Letters Patent.

Application filed Mayiz, 1905. Serial N0. 258,453.

To (/.ZZ whom it www concern:

Be it known th atl, WALFRID VALLENTHIN, a citizen ot' the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Bracelets, of which the following is a specification.

Thisinvention has reference to an improvement in bracelets, and more particularly to an improvement in the means for pivotally securing the two halves of a bracelet together.

The object of my invention is to improve the construction of bracelets, thereby providing a bracelet with a pivot-hinge constructed so as to separate the two halves of a bracelet when the bracelet is opened and to draw the halves ot' the bracelet together when the bracelet is closed.

A further object of my invention is to provide a two-part bracelet with a pivot-hinge having stops to limit the opening and closing of the bracelet.

My invention consists in the peculiar and novel construction of a two-part bracelet, each semicircular part constructed from a tubular bar and a. pivot-hinge consisting of two members shaped to fit in the adjacent ends of the bracelet, one member having a projecting lug and the other member having a recess for the lug, the end walls of the recess acting as a stop for the lug to limit the opening and closing of the bracelet, a pivot pin or pintle rigidly secured in one member and screw-threaded through the other member, whereby the opening of the bracelet separates the members of the pivot-hinge and the bracelet and the closing of the bracelet draws the members of the hinge and bracelet lirmly together, and other details of construction, as will be more fully set forth hereinafter.

and Fig. 6 is an enlarged detail sectional view of the snap, taken on like Z Z of Fig. 1.

In the drawings, c indicates one semicircular half of the bracelet, Z the other semicircular half, and e the pivo t-hinge of the bracelet.

The semicircularhalves @and Z of the bracelet are constructed from a tubular bar which is circular in cross-section. The ends c' and CZ are cut square across and coincide when the bracelet is closed. The ends c2 and Z2 are cut at an angle, as shown in Fig. 6, and a plug Z3 is secured in the end d2 ot' the semicircular halt' Z by solder or other means. This plug Z3 extends slightly above the end Z2 and forms a snap by snapping into the open end c2 of the semicircular halt' c when the bracelet is closed, thus holding the bracelet in the closed position.

The pivot-hinge e consists of a member e,

shaped to {t in the end c of the bracelet and constructed to have the central hole @2 and the oft-center lug e3, a member ai, shaped to tit into the end Z of the bracelet and having the screw-threaded central hole e5 and the offcenter recess e, with the end walls e7 and es forming a stop for the lug e3, and the pin e, having the screw-threaded portion @lo adapted to screw into the screw-threaded hole e5 in the member e?, and the reduced portion e, adapted to enter the hole @2 in the member c', as shown in Fig. 4.

The pivothinge e is assembled by rst screwing' the screw -threaded portion 61 otl the pin e into the screw-threaded hole c5 in the member e4 its entire length. The member e is now placed into position, with the reduced portion e ofthe pin extending through the hole e2, and the lug e3 extending into the recess e in the member and the whole secured together by upsetting the end 012 ot' the pin onto the end of the member e, as shown in Fig. 4. The members e and e* are now secured in the ends c and Z of the bracelet by solder or other means.

ln opening the bracelet the ends c2 and (Z2 are forced apart. The screw-threaded portion @lo of the pin counscrewing in the member eL separates the members of the hinge and the halves of the bracelet, and the end wall es ot' the recess e acts as a stop for the lug e3 and' limits the opening movement of the bracelet. When the bracelet is closed, the screw-thread- IOO ed portion @1 of the pin screwing into the member @i draws the members of the hinge and the halves of the bracelet firmly together. The end wall @7 of the recess e acts as a stop for the lug c3 to limit the closing movement of the bracelet, and the end c2 of the halil c riding up the inclined surface of the plug Z3 snaps over the protruding end of the plug and holds the bracelet in the closed position, as shown in Fig. 6.

It is evident that the two halves c and Z ot' the bracelet could be oval in cross-section and that the bracelet could have any design or configuration desired without materially affecting the spirit oi' my invention.

Having thus described my invention, I claim as new and desire to secure by Letters .Patent l. A bracelet the body of which consists of two semicircular halves, a pivot-hinge constructed of a member having a central hole and an off-center lug, a member having a screw-threaded central hole and an off-center recess the end walls of which form stops for the lug, and a pin having a screw-threaded portion adapted to enter the screw-threaded central hole in one member and a reduced portion adapted to enter the central hole in the other member, means for securing the members together, and means for securing` the pivot-hinge in the adjacent ends of the bracelet, whereby the pivoted ends of the two halves of the bracelet separate when the bracelet is opened, are drawn firmly together when the bracelet is closed, and the opening and closing movements of the bracelet are limited, as described.

2. A bracelet the. body of which is formed of two semicircular halves @and CZ secured together by a pivot-hinge, consisting of a member e having the central hole @2 and the O- center lug @3, a member e4 having the screwthreaded central hole and the onf-center recess e with the end walls e7 and e forming stops for the lug @3, and a pin c having the screw-threaded portion @lo adapted to screw into the hole c5 in the member 1, and the reduced portion e adapted to enter the hole e2 in the member c', and secured by upsetting the end of the reduced portion @monto the end of the member e', whereby the opening of the hinge will separate the members of thehinge, the closing of the hinge will draw the members of the hinge firmly together, and the opening and closing movements of the hinge are limited, as described.

3. ln a bracelet, the combination of the tubular semicircular halves c and CZ the ends c' and d of which are cut square across and the ends 02 and (Z2 at an angle, of a pivot-hinge e consisting ot' a member e shaped to fit in the end c oil the bracelet and having the central hole e2 and the off-center lug e3, a member e* shaped to tit in the end Z of the bracelet and having the screw-threaded central hole c5, the off-center recess e with the end walls e7 and @s forming stops for the lug e3, and apin c having the screw-threaded portion ew adapted to screw into the hole c5 in the member c", and the reduced portion @u adapted to enter the hole in the member e and secured in the member by upsetting the end onto the end of the member e', means for securing the pivothinge in the ends c and d of the bracelet` whereby the opening' of the .bracelet will separate the pivoted ends of the two halves c and Z of the bracelet, the closing of the bracelet will draw the halves of the bracelet firmly togetlier, and the opening' and yclosing Inovements of the bracelet limited, and means for holding the bracelet in the closed position, as described.

In testimony whereofI have signed my name to this specilication in presence of two witnesses here subscribed.

VALFRID VVALLENTHIN.
