Application filed. July 24,1923. Serial No. 653,444.

To all whom it may concern Be it known that 1, Max JEnsEMANN, a citizen of the. United States, residing at New York, in the county of New York and State of New York have invented certain new and clamps.

useful Improvements in Clamping Devices for Rings and Other Articles, of which the following is a specification.

My invention relates to means for exhibiting jewelry, and more particularly consists in a resilient clamping device, whereby pieces of jewelry, such as rings and the like are held in a secure position, sothat they cannot drop down.

My new clamping device is composed of but few parts, which can be easily fastened in place and are very cheap to manufacture.

In the drawing, in which I have shown for the purpose of illustration one embodiment of my invention, Fig. 1 shows the corner of a show-card having fastened therein the new clamp. Fig. 2 is an end view as seen from the right in Fig. 1, "a ring being shown in broken lines held by one of the Fig. 3 is a section along 33 in. Fig. 1. Fig. 4 is a rear view of a portion of the showcard showing how the clamping device is fastened in the back. Fig. 5 is a perspective view of the clamping device without the hook. Fig. 6 is a perspective view of the hook, and Fig. 7 a modification of the hook.

The body portion 1 of the clamp is a piece of thin sheet metal stamped out in the center, so as to form two wings 23, leaving a rectangular opening 1. Above the said opening, the body portion 1 is slitted to form a loop 5, adapted to receive the flat end of a bowed leaf-spring 6, located in front of the rectangular opening hand bulging out towards the front.

Below the rectangular opening 4., the body portion 1 is slitted from thesides as shown in 7, 8, in Fig. 5, thereby forming two lugs 9 and 10. These lugs are bent backwards as shown in Fig. 4, so as to grip the lower off-set end 11 of a hook 12, adapted to cooperate with the leaf-spring 6, and extending upwardly in front of the rectangular opening, as clearly shown in Fig. 3. The hook 12 per se is shown in Fig. 6.

Clamping devices such as the one above I described can be inserted in a showcard 13 as shown in Fig. 1, which card for that pur pose is provided with rectangular openings 14. The clamping device is inserted into these openings, so that the wings 2-3 extend forwardly, and the wings are then bent down flat against the card as shown in Fig. 1, whereby the body portion 1 is firmly held in position, the bowed leaf-spring extending through the opening 14; to the front side of the card. Then the hook 12 is placed in position as shown in Fig. 3, and the lug portions 9, 10, of the body portion 1 are bent around the lower off-set end 11 of the hook, so as to firmly grip the same.

When a ring. such as shown at 15 in Fig. 2 is now slipped over the hook 12, the spring 6 will firmly engage the ring, so that it is securely held in a substantially horizontal position as shown in Fig. 2, preventing the ring from moving, no matter to what position the show-card 13 is turned. The ring can be easily slipped over the hook 12, but when once in the position as shown in Fig. 2, the spring 6 pressing against the ring prevents the same from becoming dislodged.

In Fig. 7, I have shown a slightly modified hook 12, by providing short lateral extensions 16, 17. These extensions are intended to form an additional support for a ring which is very thin, and therefore has the tendency to turn on the hook.

The hook 12 may also be made of metal, or of celluloid, or bone, or any other suitable material, and if desired, the hook can be covered with thesame fabric with which the show-card 13 is covered, as shown at 18 in Fig. 1.

Instead of securing the clamping device in a show-card, it can of course be also secured in individual supports intended to exhibit pieces of jewelry.

I claim as my invention.

1. In a clamping device, the combination of a body portion having wings stamped from the. material of said body portion, and leaving a central. opening therein, a resilient means within said opening held in place by said body portion, and a separate hook adapted to be fastened to said body portion, so as to cooperate with the said resilient means. the said body portion below the centralopening being slit-ted at both sides, so as to form lugs adapted to be folded around and to grip the lower off-set end of the said hook for holing the same in position.

2. A clamping device, comprising a body portion having wings stamped out therefrom, so as to leave a central opening in said body portion, a leaf spring held by said off-set portion of the said hook for securely body portion, so as to project into said open holding the same in said position. 10 ing, and a hook adapted to be fastened to 3. A clamping device as set forth in claim said body portion and projecting upwardly 2, in which said hook is provided with short in front of said leaf spring to cooperate lateral extension for the purpose described. therewith, the said body portion being In testimony whereof I affiX my signature. slitted at both sides, forming lugs adapted to be folded around and to grip the lower MAX J ERSEMANN.
