WATCH-CASE CENTER AND PENDANT.

SPECIFICATION forming part of Letters Patent No. 251,399, dated December 27, 1881.

Application filed August 17, 1881. (Model) To all whom it may concern Be it known that we, EDWIN HERBERT ARMS and ROBERT JoHN QUIGLEY, both of the city of Toronto, in the county of York and Province of Ontario, Canada, watch-case manufacturers, have invented certain new and useful Improvements in the Construction of Watch- Oases, of which the following is a specification.

The principal object of the invention is to produce a watchcase which can be completed, after having been fitted at the lathe, without being subjected to the usual method of heating and reheating for the purpose of soldering on the pendant, hinges, and thumb-pieces; and it consists, essentially, of pivotally attaching the pendant upon a sleeve screwed into the case or secured thereto in any other way without solder, the bezels and lids being held to the center by the snap only, there being no hinges, the pendant having a cam or projection on its hub for opening the lids, substantially as hereinafter explained.

In the drawings, Figure 1 is a perspective view of our improved watch case as it appears when placed together. Fig. 2 is a perspective view of the center, with the back bezel only in position. Fig. 3 is a perspective view of the front bezel and back. pendant. Fig. 5 is a detail of the sleeve, showing it screwed into the ring, which is partially exhibited within a portion of the center. Fig. 5 shows the ring by itself.

In the drawings, A is the center, which may be made exceedingly light, as it is not called upon to bear any strain in connection with the other parts of the case, which, in fact, when put together, tend to strengthen each other.

Instead of inserting a spring in the inner recess made in the center A, we substitute a steel ring, B, made in sections b, as shown in Figs. 5 and 5, not only for the convenience of insertion within the recess, but also to permit of expansion when in position. The sleeve 0, whose tapering and threaded lower end is screwed in position, as shown, to expand this sectional ring, forms a bearing for the pendant D, and is made hollow to permit the passage of the stem E employed for windin g the watch.

' which they are fitted to the center.

Fig. 4 is a detail of the The ring B is necessarily made in sections, in order to introduce it into the case center, and as the tapered screw of the sleeve 0 screws between the ends of two of the sections all the sections are spread outward, and practically form a single ring, to strengthen and support the case, and at the same time serve as the means of securing the sleeve 0 to the case. A small set-screw, a, passing through the pendant and the slot in the sleeve 0, holds the stem in position longitudinally, while permitting it to be turned freely for the purpose it is intended to perform.

On reference to the detail view of the pendant D it will be noticed that there is a cam or projection, (1, formed on one side of its hub, which fits into a notch or recess, 0, cut in the case rim or center A, as shown. As the pendant D is carried on the sleeve 0, so that it can be revolved thereon, the projection cl is employed for springing off the back and front lids, which are held on by the correctness with When the case is put together, as shown in Fig. 1, it will be found dust-proof, the joints being made a perfect fit in the lathe.

The foregoing description relates to a case made for a stem-winding watch. When made for an ordinary key-winding watch a stem or spindle may be substituted for the sleeve (3, holding the pendant D in position, and instead of screwing a sleeve or spindle into the ring B it may be screwed, riveted, or otherwise secured to the center.

What we claim as our invention is-- 1, In a watch-case, and in combination with the center Av and pendant D thereofl'the spindle or sleeve 0, secured to the center A and forming a bearing upon which the pendant is pivotally held, substantially as specified.

2. In a watch-case having its lids fastened to the center by the snap' only, the combination of a pendant pivotally held in a bearing formed on a sleeve screwed into the center or a ring within the center, and provided with a cam or projection arranged for the purpose of opening the lids, substantially as specified.

8. In a watch-case, the combination of a pendant pivotally held on a sleeve or spindle screwed into or otherwise secured to the centor without solder, and provided with a cam or and fitting into a recess made in the center be- :0 projection arranged for the purpose ofopening tween the lids, substantially as and for the the lids, substantially as specified. purpose specified.
