N 1931- v H. STOCKERT LINK BODY FOR JEWELRY PURPOSES Filed March 18. 1929 Patented Nov. 3, 1931 HERMANN STOGKERT, OF PFORZHEIM, GERMANY LINK BODY FOR JEWELRY PURPOSES Application filed March 18, 1929, Serial No. 348,079, and in Germany November 10, 1928.

The invention relates to a hollow link body for use chiefly for making articles of jewelry such as necklaces, bracelets and the like.

The novelty consists in that the walls to- [5 gether with the bottomor end walls consist of one single continuous piece obtained by stamping.

Several embodiments of the invention are illustrated by way of example in the accom- 1 panying drawings in which:

Fig. 1 shows in perspective view a dieshaped link-body.

Fig. 2 shows in plan view the corresponding stamped piece. 15 Fig. 3 shows a portion of an articulated band with three consecutive die-shaped links.

plate of which the cylindrical link is made.

Fig. 9 is a cross-section on line 99 of Fig. 8.

Fig. 10' shows a longitudinal central section of the cylindrical body illustrated in Fig. 7.

F ig. 11 shows a portion of an articulated link band composed of three cylindrical links. Fig. 12 is a perspective View of a conical link.

Fig. 13 shows in plan view the stamped plate from which the conical link illustrated in Fig. 12 is formed.

Fig. 14 shows a portion of an articulated link band composed oftwo conical link bodies and one cylindrical link body.

The forms of construction illustrated in the accompanying drawings are only shown by way of example. Without departing from the fundamental idea of the invention link bodies of other shapes can evidently be made, in the same manner .e. g. quintagonal, octagonal, and other multi-sided prisms, as well as pyramids and frustrum of a pyramid, frustrum of a cone and others.

The stamped plate comprises, according to the invention, all the sides of the body, i. e. not only the side or wall porti n5 (1, b, c, d but also the bottom or end faces 6, f, g, it, these latter being connected with the side or wall portions a, b, c, d by means of a short neck 2', la, Z, m so that, when being folded over for the purpose of forming the link body from the stamped plate, they can be brought into a lower position corresponding to about the thickness of the material, whereby the outer sides of the bottom portions 6, f, g, h are absolutely or approximately flush with the end edges n, 0, p, g of the side or wall portions a, b, 0, d of the link bodies.

In order to prevent open joints, such as might form between the sides or wall portions a, b, c, d and the end portions e, f, g, h a groove 7" is pressed along the end edges n, 0, p, g with which the edges of the bottom portions e, f, g, k engage when the link-body is being formed. Consequently it is not necessary to solder along the edges.

The bottom plates e, f, g, k are outwardly curved in order to limit the contact surfaces to a single point when the link members are threaded on a carrier 8 and especially in order to prevent the edges and corners of one link body rubbing against the end faces of adjacent links. Moreover one or more holes t are provided in the end plates to allow the passage of the carrier 8.

The individual links may be fashioned and decorated as desired, specially the side or wall plates a, b, 0, (Z may be decorated by pressing engraving, guilloching, enamelling, by setting with stones or in any other manner.

The chief advantage of the link body consists in the hollow, cheap production from a single stamped plate whereby the fixing of the end plates 6, fig, h in the side or wall portions a, b, 0, d with which they are already rigidly connected, is considerably simplified and improved.

I claim 1. A hollow link-body for jewelry purposes, in which the side plates and end plates are formed of one single stamped plate the end plates being connected to the corresponding side plates by means of a short neck adapted to enable said end plates to be bent so that they assume'a position lower by about the thickness of the material than the adjoining edges of said side plates whereby the outer surfaces of said end plates are approximately flush with said adjoining edges 2. A hollow link-body for jewel purposes, in which the side plates and en plates are formed of one single stamped plate the end plates being connected to the corresponding side plates by means of a short neck adapted to enable said end plates to be bent so that they assume a position lower by about the thickness of the material than the adjoining edges of said side plates whereby the outer surfaces of said end plates are approximately flush with said adjoining edges, said adjoining edges being provided with a groove into which the edges of the end plates engage to prevent formation of 0 en joints.

In testimony whereof I my signature.

HERMANN STOCKERT.
