Description
Patented Apr. 3, 1951 UNITED STATES PATENT OFFICE Application November 25, 1946, Serial No. 712,102 In Switzerland April 26, 1946 4 Claims. 1
In square, rectangular, and more generally, polygonal watch-cases, it is extremely diflicult to make the glass dust-tight.
Dust finds its way through the joint between the case-band with rim and the edge of the watch glass into the movement. Many methods have been devised to obviate this difficulty, but the solutions are far too complicated.
The aim of the present invention is to attain this end with a minimum number of parts. The invention relates to a polygonal watch-case having a tubular bezel, which fits over the middle part of the watch, this watch-case being characterised by the fact that it is constructed of a watch glass of special form in a synthetic material, the edge of which is squeezed between the rim of the bezel and the upper side of a frame of angle-shaped section; one side of this frame pressing on the edge of the dial.
The attached drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 is a view in perspective, partly in section, and
Fig. 2 is a section on a larger scale than the one of Fig. 1, in a perpendicular plane.
In the drawing, l designates the bottom of the watch-case, which carries a supporting ring 2 soldered to it; the latter forms, together with an inset frame 3 adjusted grease friction tight upon the ring 2, the middle part of the watch. The inset-frame 3 is of angle-shaped profile, the upper side of which is carefully trued up.
The tubular bezel 5 fits over the lateral surface of the bottom I and the inset-frame 3. latch-glass 6 with flange l is made in one piece from synthetic glass. This flange is squeezed between the upper side 4 of the frame 3 and the portion 8 of the bezel. The lower surface of the flange I resting on the part 4 is trued up at the same curvature as the latter.
The movement 9 is carried by the supporting ring 2. The inset-frame 3 holds it in place by slightly pressing with its part 4 0n the rim of the dial [0. The pressure is produced on fixing the bottom to the bezel with the help of the notch II.
The preceding description relates to square, rectangular, or, more generally, polygonal watch-cases. We understand by this latter term any watch-case having at least four sides, straight or curved.
What I claim is:
1. In a dust-proof fancy watch case, a combined bezel and center including a flange, a bottom fixed to said combined bezel and center and having an upstanding peripheral portion encompassed by the bezel, a movement-supporting frame supported on said bottom and abutting the inner surface of said upstanding portion, an
The
angle-shaped inset frame having a vertical section snugly fitting between said movement-supporting frame and said bezel and having a lateral section provided with an upper trued up surface, and a crystal made from synthetic material having a rim including a lower trued up surface in dustproof contact with said trued up surface of the lateral section and being clamped fast between said lateral section of the angleshaped inset frame and said flange.
2. A watch case comprising a bottom having an upwardly flared rim, an upstanding flange on said rim, a bezel having its lower vertical section encompassing the flange, cooperative locking means formed on the lower section of the bezel and on the bottom flange, a movement supporting frame mounted on the bottom rim and engaging the inner surface of the flange, an angle shaped inset frame having a vertical section mounted on the upper edge of the bottom flange and engaged between the lower section of the bezel and the movement supporting frame, and having a substantiall horizontal section underlying in spaced fashion the upper lateral flange of the bezel and overlying the movement supporting frame, said section having an upper trued up surface and a crystal having a peripheral flange clampingly engaged between the substantially horizontal section of the inset frame and the upper section of the bezel, said under surface of the crystal flange being trued up and mating with the trued up surface of the inset frame section.
3. The combination of claim 2, wherein said movement supporting frame is formed with a beveled lower edge abutting the bottom rim at the juncture between the rim and the flange and with an enlarged upper end supporting the watch movement.
4. The combination of claim 2, wherein said lower section of the bezel has an oblique lower edge disposed coplanar with the rim of the bottom.
WERNER SCHMITZ.
