WATCH CASE A Filed March le, 1954 -fv- 2 www United States Patent O WATCH CASE Hans-Jean' Steimann, La Chaux-de-Fonds, Switzerland Application March 16, 1954, Serial No. 416,645 Claims priority, application Switzerland March 17, 1953 Claims. (Cl. 58-90) The present invention relates to a watch; this watch is characterized by the feature that its work is located in a caging frame or ring which holds it in place and which is provided, on its outer face, with an annular shoulder constituting a tighting member, pinched between a bearing surface of a member of the casing and a shoulder of the bottom, this latter being secured to the body of the casing.
The annexed drawing shows, by way of example, three embodiments of the object of the invention.
Fig. 1 is an axial section of a part of the first embodiment, and
Figs. 2 and 3 are partial sections of the second and third embodiments respectively.
The casing of the watch shown in Fig. l comprises a body-rim 1 in which is seated a glass 2. The bottom 3 of the casing is provided with a shoulder 3a threaded in a flange 1a of the body-rim. The work 4 is located in a cap-shaped protecting member 5 made of plastic matter, on the edge 6 of which bears the shoulder 7 of the base-plate of the work; this cap-shaped protecting member 5 constitutes thus a caging frame or ring. It is fitted in the body-rim 1; it shows an annular outer shoulder 5a pinched between the shoulder 3a of the bottom and a bearing surface 8 of the body-rim. This shoulder 5a constitutes the thinnest part of the protecting cap-shaped member and constitutes a tighting joint between the bottom and the body-rim.
In the embodiment of Fig. 2, the protecting capshaped member constituting the caging frame in which is located the work 4, is engaged in a cap-shaped glass 10; the shoulder 9a of this protecting cap-shaped member is pressed by the shoulder 3a of the bottom 3 against the edge 11 of the cap-shaped glass 10. This latter shows an outer bearing surface 10a pressed, by the axial pressure produced by the bottom, against an inner bearing surface 12 of the body-rim designated by 13.
At last, in the embodiment of Fig. 3, the cap-shaped glass is made of two parts and comprises a part 14 constituting the glass itself and a part 15 constituting the lateral wall of the cap in which is introduced the protecting cap-shaped member 16 of the work 17; the shoulder 16a of this cap-shaped member is pressed by the shoulder 18a of the bottom 18 against the edge 19 of the lateral part 15 of the cap-shaped glass. The part 15 is made of plastic matter; it could also be made of metal.
