GEORGES HENRY, 015 GENEVA, SWITZERLAND.

WATCH.

Application filed March 15, 1922.

To all whom it may concern:v

Be it known that I, GEORGES HENRY,a citizen of the Republic of Switzerland, residing at Geneva, Switzerland, have invented new and useful Improvements in Watches, of which the following is a speci fication.

. This invention relates to improvements in watch cases, more particularly to improvements and means for retaining the bezel in position relative to the cover.

In pocket watches, bracelet watches and other implements of this kind. which consist of a closed case formed of at least two elements, the joining of the two elements is obtained by providing said members with screw threads or the like. To that end the elements to be united must consist of either screwed organs or grooves, which is very expensive and the life of which is very short.

The object of the present invention is the provision of means whereby the joining of the element of the case requires neither groove nor screw thread. The improvement is typical in that the watch consists of at least one element which is engaged on an interior brim of the bezel to maintain thiselement in its proper position relative to the cover.

In the drawings accompanying and forming part of this specification,

Fig. 1 is a plan view of the cover of the case on which the bezel is secured;

Fig. 2 is a plan view of the bezel seen from the inside;

Fig. 3 is a fragmentary section taken approximately on the line A-BC of Fig. 2; and

Figs. 4 and 5 are fragmentary sectional views taken approximately on the line D-E of Fig. 1.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

The watch case consists of two elements, namely the cover 1 and the bezel 2 bearing the glass or crystal 3. The cover 1 is provided with a flat brim 4 consisting of two shoulders 4, 4". A flat spring 5 is disposed in the cover 1 and extending for about three fourths the circumference of said cover, and being constantly under tension. On the upper end of the spring 5 there are disposed a plurality of tongues 6, in the present instance being 3 in number, each of Serial No. 543,848.

which passes through a notch 7 provided in the brim 4 of the cover. The tongues 6 project over the brim 4 of the cover and are curved outwardly at their upper end.

The bezel 2 is also provided with an interior brim 8, the breadth of which corresponds to the breadth of the shoulder 4 of the cover. This brim 8 of the bezelis provided with a plurality of notches 9, in the present instance being 3 in number, which corresponds to the 3 tongues 6 of the spring 5. A fourth notch 10 is provided on the bezel and is used as a mark and is placed opposite the stem-winding 11 of the watch at the time of setting the bezel in place.

In order to secure the bezel on the cover 1, it is necessary to place the bezel on the shoulder 4 of the brim 4 so that the curved extremities of each of the tongues 6 are placed opposite a notch 9 of the bezel as shown in Fig. 4. The bezel 2 is then turned on the cover so that the tongues 6 become engaged on the brim 8 of the bezel and thereby secure the bezel to the cover. The tongues 6 acting as a spring, it is obvious that the bezel will fit perfectly on said cover. In order to take off the bezel, it is simply necessary to turn it in the opposite direction so that the notches will again be brought back opposite the tongues 6.

In the form shown, the tongues 6 are formed integrally with the spring 5 which also assists in maintaining the movements of the watch in the cover 1. For this purpose, the spring 5 has several notches 14 in each of which projects a hook 12 of the movements 13, as shown in Figs. 4 and 5. However, other elements might be substituted in place of the tongues 6 in order to fix the bezel in place.

It is of course understood that various changes and modifications may be made to the details of construction withoutdeparting from the spirit or scope of the invention.

Having described my invention, what I claim is:

1. A watch case comprising a cover having an interior brim, said brim having a plurality of notches therein, a bezel having an interior brim, said brim having a plurality of notches therein, a spring disposed in said cover and passing through the notches in the brim of the cover, a shoulder provided on said bezel, said bezel being adapted to be rotated to bring the upper end of said spring
