R1637? 2' were a LINK FOR CHAIN AND DETACHABLE HINGES FOR J3EE SAME.

Application filed June 27,

To all whom it may concern I Be it known that l, BERNARD llLlnsTnKiN, a citizen of the United States of America, and a resident of l vashington, District of Columbia, have invented a new and useful Improvement in Links for Chain Bracelets and Detachable Hinges for the Same, of which the following is a specification.

lhen carrying bracelets in stock a large number is required to meet all the demandsas to size. To a great extent this may be avoided in the so called chain bracelet by preparing detachable links ready for assembly to build up a braclet of any desired size. One object of my invention is to make such a detachable bracelet link. .nnother object of my invention is to provide a bracelet link vith. a. detachable hinge of strong and durable construction without sacrificing the beauty of the assembled bracelet. Another] object of my invention is. to make such a hinge not only easy and quick for assembly but to also provide means for detaching any link without the intervention of a skilled mechanic. Another object of the invention is to make a bracelet link and a hinge therefor in such a manner as to build up a chain bracelet without the necessity of swaging the hingepivots.

in the drawing which forms a part of my specification Figure 1 shows a perspection view of several links connected.

tel'erring in detail to the drawing: 1 represents a link made up of walls of any de- 1922. SeriaI No. 571,311

- sirable thickness and from any metal such as silver, gold or platinum having a pro vision generally indicated 2 for a gem or gems on the top wall. The bottom wall, three being left open and the edges made smooth since the said edges come into con tact with the .skin.

In the form shown in Figures 2, 3 and 5, each link is provided with a hinge pin, 1:, at

one of the end faces and a socket, 5, at the opposite end face. The end faces are beveled oii' from midway toward the lower face of the link as shown at 6, so as to permit the assembled bracelet to ties into an annulus. The hinge pin is best shown in Figure 6. It consists of a piece of halfround rod bent into U shape with the flat faces of the half.

round rod facing each other clearly shown 1n the drawing. The arm 11', of the hinge pin differs from the companion arm 12, in

that it has a shoulder, 9 at the free end there of. The arm 12 is permanently attached to the end face of the link by soldering or it may be made integral with the end face. 'he webb 8, of the li-shaped hinge pin is slightly springy even after. it has been heated, so that the tendency for the two arms 11 and 12 is to stay slightly spread apart as shown in Figure 6.

The socket is formed by soldering on the inside of the end face, of the link, a piece of tubing, 1 1-, with a portion cut away along a chord. The inner diameter of the tubing being slightly larger than the diameter of the pin Of the two faces 16 and 17 one face is formed with a socket opei'iing as shown at 18 (Figure ,9) the opposite fare being left closed. The socket opening 18, is formed in sliding lit with the hinge pin so that there is formed a retaining shoulder 15 which cooperates with the shoulder 9 on the hinge pin. A small hole, 20, is also provided in the socket tubing as seen in Figure a. l l hen assembling one link to another the two links are placed so that the end 8 of the hinge registers with the socket opening 18 of the other link. The pin is then slid endwise into the socket the prong 11 approaching 12 until the shoulder 9 reaches beneath the inside of side face 16 when it snaps out due to the slight springiness of the web 8, the parts assuming the relative positions illustrated in Fig. 11 and thus forming a safe and strong catch.

7 pointed tool can be used'for one or the other ofthe prongs 11 or 11? as I provide each of the socket tubes with a hole 20.

The pins shown at Figures 8 and 10 differ by a slight change and one or the other -may be used for mere mechanical convenience.

I claim: 1. A1cha1n link for a bracelet compr1s1ng a socket adapted to receive a hinge Ipin, a. split hinge pm to fit said socket, said socket being contained in theend face 'ofthe. link, a longitudinalslot inthe' face of the link communicatingwith said socket and complementary detents on the hingepin and socket;

' 3; A hinge pin for" chain link-bracelets having two-prongs and a middle body, said prongs being vyi'eldingly held at a space from .the said middle body, and locking shoulders on said rongs. g I

4:; A clam" for a bracelet having a socket along its end face, a longitudinal slot com- The hinge- Laauaso municating with said, socket, a perforation in the wall of said socket opposite the slot and a pin retaining shoulder in said socket.

5. A chain link for 'a bracelet having a longitudinal slot ingits end face, a socket communicating with said slot, a retaining shoulder at one end of said socket and a hole in the wall of said. socket opposite the slot and near the retainingshoulder, a yielding split hinge pin to fit into said socket and to be retained by saidjshoulder.

'6. A chain link for a bracelet having a socket ad acent its end face, alongitudinal slot comiininieating with said socket through the I end face a retaining shoulder in said socket, a hinge pin to disconnectedly fit into said socket and means permitting the "removal of said hinge pin. p

' 79A chain link for a bracelet having a socket adjacent its end face, a longitudinal slot communicating through the "end face to the socket, a retaining shoulder. in said socket, a split pint'o disconnectedly enter saidsocket, a shoulder on said pin to co operate with the shoulder in the socket-and meansfacilitating the disconnec'tion of said pin from the socket.

' 8. A chain link for a bracelet and hinge thereof comprising abox like body and a hinge socket at theendface thereof,'a split hinge pin and detachable locking means be tween the socket and pin.
