CUFF LINK Filed March 8, 1955 Patented July 28, 1936 UNITED STATES PATENT OFFICE Application March 8,

1935, Serial No. 10,066

In France March 14, 1934 6 Claims.

It is known to connect the plates of cuff-links with their connecting arms and to interconnect these arms in such a manner that the parts are capable of moving relatively to one another. Hinge joints arranged either only between the plates and their arms or only between the arms themselves are employed as connecting members. These joints, as is known, allow the arms or the plates to swing only in one and the same plane, whereas the other connections, that is in the first instance between the arms and in the second instance between the plates and their arms, are constructed like eyes so that the arms or the plates are free to swing in all directions. Thus, the parts of the cuff-link have ample latitude of movement, which is undesirable and prevents a uniform holding together of the edges of the cuff.

This invention relates to a cufi-link, in which both the connection between each plate and its arm and also that between the arms are constructed as hinge joints and either all these hinge joints or at least those between the plates and their arms are equipped with spring detent means which automatically lock the connected parts either in their relative extreme positions or at least in their closed position.

Two embodiments of the invention are illustrated by way of example in the accompanying drawing in which:-

Fig. 1 shows in side elevation a cuff-link in opened out position.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a side elevation of the link in its intermediate position.

Fig. 4 shows the link in side elevation in closed position.

Fig. 5 shows a hinge joint with arresting means in section on line V-V of Fig. 2.

Fig. 6 shows a simplified form of construction in side elevation.

Fig. 7 is a cross section on line VIIVII of Fi 4.

The cufi-link consists of two plates l and 2, designed to bear against the outer side of the cuffs and each having on its inner side at one end a prismatic hinge body 5 with pins 4a. projecting laterally one from each side of the hinge body. A connecting arm 4 is hingedly mounted at one end on the pins 40. of each of the hinge bodies 5, the other end of the arms 4 being hinged on pins of a middle prismatic hinge body 6. The connecting arms 4 consist of plates of resilient material of a width preferably corresponding to but in any case not exceeding the length of the link holes in the cuffs. Tongues 9, l0 are formed in the arms 4 by slots 40, and coact with the prismatic faces of the hinge bodies 5 and 6 respectively and thus constitutes detents for arresting the parts connected by the hinge joints in their two extreme initial positions as illustrated in Fig. 5.

For the purpose of closing, the cuif-link, after it has been inserted in the cuff holes, is first brought from the position illustrated in Fig. 1 into the intermediate position shown in Fig. 3 by swinging the arms 4 in the direction of the arrow :c, and then into its closing position by swinging the plates I, 2 in the direction of the arrow 11 in which position the material of the cuff II is clamped between the parts I, 4 and 2, 4 respectively. The free ends of the plates I. and 2 are then directed towards one another so that the cuff is additionally held together near its outer edges.

The simplified form of construction illustrated in Fig. 6 differs from that above described in that the inner ends of the arms 4 are merely connected by means of a hinge pin l2 so that this middle joint has no arresting means. This presents the advantage that the joint l2, when the link is in closed position, can open slightly and consequently only the outermost edges of the cufi are held together.

The freedom of oscillation of the hinge joints is limited in both forms of construction so that the link can only be folded in M-shape.

I claim:-

1. A cuff-link, comprising in combination two plates, hinges one on the under side of each of said plates, two arms each mounted at one end on one of said hinges, a hinge joint interconnecting the other end of said arms, and spring detent means at least at the hinges connecting said plates with said arms and adapted to automatically lock the above interconnected parts at least in their closed position.

2. In a cuff-link as specified in claim 1 means for limited swinging movement of said hinges so that the link can only be folded in M-shape.

3. A cuff-link as specified in claim 1, in which the hinges between the plates and arms are ar ranged outside the middle of the plates.

4. A cuff-link as specified in claim 1, in which the hinges between the plates and the arms are arranged at one edge of the plates.

5. A cufi-link as specified in claim 1, in which the hinges between the plates and the arms are arranged one near one end of each plate and the ends of the plates remote from the hinges are curved and adapted to press against the outer side of the cuff when the link is in closed position.

6. A cuff-link as specified in claim 1, in which the arms each consist of a plate of a width not exceeding the length of the button hole in the cufi, said plate having longitudinal slots dividing the plate into resilient tongues and said spring detent means consisting of blocks at the hinges adapted to coact with said resilient tongues.
