METHOD OF FORMING WATCHCASE-PENDANTS.

Specification of Letters Patent.

Patented Sept. 1'7, 190'?- To all whom it may concern:

Be it known that I, GEORGE A. DERFLER, a citizen of the United States, and a resident of Riverside, in the county of Burlington and State of New Jersey, have made and invented certain new and useful Improvements in Methods of Forming Watchcase-Pendants, of which the following is a specification.

My invention relates to an improved method of forming watch case pendants, and more particularly to that kind or style thereof usually known and referred to as antique, characterized by an oval-shaped enlargement in the center thereof, adapted to receive and contain the ends of the bow.

The object of the invention is to devise a method to simplify and cheapen the construction, and particularly those antique pendants wherein the outer side or surface thereof is covered with gold or precious metal, and which have heretofore usually been constructed of what is known as filled gold; also, to devise a method wherein the resulting pendant will be of such construction or formation that it will practically be solid, and particularly in the ends of the oval-shaped enlargement, wherein the ends of the how are contained. Usually thesependants are constructed of sheet metal, the ends of the oval-shaped enlargement being recessed or indented to receive the ends of the bow, which recesses in the course of time, wearthrough, thereafter allowing said bow to swing and move loosely therein.

With these and other ends in view, the invention consists in the novel method hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 illustrates a blank in the form of a shell, adapted to form the outer covering for the pendant. Fig. 2 is a plug or rod of base metal, and employed to form the interior or body of said pendant. Fig. 3 shows the metal rod inserted in the shell. Fig. 4 shows in elevation, the rod and shell stamped up into a form approximating that of the pond ant. Fig. 5 is a sectional view of the same. Fig. 6 is a view of the pendant in its next stage of formation, and Fig. 7 a sectional view thereof. Fig. 8 shows the finished pendant.

Referring to the drawings, A represents the shell, preferably formed of gold or other precious metal, forming in the finished pendant, the outer covering for the base metal body of the pendant. While I prefer to form this shell of thin gold, it will of course be understood that it may be formed from filled gold, that is, a metal comprising two outer thin sheets of gold with base metal between them.

To form the body or interior portion of the pendant, I employ the rod B, preferably of brass or other base metal, which will nicely fiow under the action of forming dies, this rod being of such a diameter as to nicely fit within the shell A, as illustrated in Fig. 3, and of somewhat greater length, in order to form the hub O of the finished pendant, and over which hub fits the crown (not shown), said hub being uncovered or unprotected by precious metal, as the same in this type or character of pendant, is entirely concealed within the crown.

After the shell A and rod B have been assembled, as above described, they are subjected to the action of a pair of suitable dies, not shown, whereby they are shaped, as illustrated in Fig. 4, that is, approximating the shape or form of a pendant, the hub B correspond: ing to the projecting end of the rod B of Fig. 3, the remaining portion of the article being covered by the shell A By means of suitable tools, a portion of the rod B is then drilled out, leaving an interior body or shell D, (Fig. 7), provided with solid oval portions D and hub O, and at the same time, or subsequently, a groove or recess D is cut into the base metal portions D for the reception of the winding crown, which as in ordinary cases, fits around the hub O.

The shell A which covers the body D of the pendant with the exception of the hub O, at any desired stage of its formation is provided with the indentations or recesses D for the reception of the ends of the bows, and as this portion of the shell is backed by the base metal D said ends of the bow are constantly provided with a solid bearing, even through the outer precious metal covering in time be worn through.

The end of the pendant, which is usually soldered or otherwise secured to the watch case center, is knurled or otherwise ornamented with the grooves D to impart thereto a neat and finished appearance.

This method of forming a pendant is a comparatively cheap and inexpensive one, as it involves but little labor. Furthermore, the outer covering of precious metal is extended over those portions only of the pendant which are exposed to view, and as the shell may be made exceedingly thin, backed, as it is by a base metal body, a material saving in the cost of the finished pendant, is thereby effected.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

GEORGE A. DERFLER.
