WATCH-OAS E.

SPECIFICATION forming part of Letters Patent No. 284,926, dated September 11, 1883.

(No model.)

To aZZ whom it may concern.-

Be it known that I, WM. N. IVnnnnN, of Vaterbury, in the county of New Haven, and in the State of Connecticut, have invented cer tain new and useful Improvements in IVatch- Cases; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a perspective view of my casecenter from the front side. Fig. 2 is a like view of the same from the rear side. Fig. 3 is a section of the pendant and the case upon each side of the same-upon line a; .r of Fig. 2, and Fig. I is a perspective view of the bushing for the push-pin and ring opening.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to simplify the construction and to lessen the cost of a watch; and to this end it consists, principally, as a new article of manufacture, in a watchcase center and pendant cast in one piece and adapted for use without fitting, substantially as and for the purpose hereinafter specified.

It consists, further, as a new article of man ufacture, in a watch-case pendant formed by casting molten metal around a sheet-metal core, which constitutes the openings for the push-pin and ring; substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents a casecenter provided within its front side, at its inner corner, with a right-angled rabbet, a, for the reception of the dial, at its outer corner with a second rabbet, a, for the reception of a bezel, and within its back side with similar rabbets, a? and a", for the reception of a cap and a case-back. At a point slightly in front of the bottom of the rabbet a is a notched ring, a, for engagement with a stoppawl.

From one side of the periphery of the casecenter A a pendant, B, of usual size and form, projects radially outward, and is provided with an axial opening, I), for the reception of a push-pin, and within opposite sides has recesses b for the reception of the ends of a ring.

As heretofore constructed the case center Ahas been turned out of a ring of cast metal, the notched ring chas been cut with dies from a sheet of metal,and then attached to said center, and the pendant B has been turned out of a bar, its push-pin and ring openings Z) and I) respectively drilled, and said pendant then inserted withina hole drilled in said case-ecu ter aud secured in place by heading or riveting down its inner end. By my method of construction the case-center, notched ring,and pendant, complete and ready for use, are formed at one time and in one piece from cast metal, a steel mold accurately proportioned and highly finished being used for the reception of the molten metal, and pressure used to cause the latter to perfectly fill every portion of said mold, the result being a large saving in expense over the method heretofore em ployed.

In order to produce the push-pin and ring openings 1) and 1) within the pendant B, I employ a bushing, (shown in Fig. 4,) which is composed of two pieces of sheet metal, 0 and 0, each corresponding to the shape of one-half of said cross-openings, which parts are placed in position within the mold and metal run around them,the result bein p erfcctly-iormed openings lined or bushed with sheet metal.

IVhile my method is described as applied to one especial form of case-center, it will be seen that it may be applied to the production of any form of case-center employed upon watches.

Having thus fully set forth the nature and merits of my invention, what I claim is- 1. As a new article of manufacture,awatchcase center and pendant cast in one piece, and adapted for use without fitting, substantially as and for the purpose specified.

2. As a new article of manufacture,a watchcase pendant formed by casting molten metal around a sheet-metal core, which constitutes the openings for the push-pin and ring, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of May, 1881.
