WATCHCASE, 8w.
Specification of Letters Patent.
Patented Jan. 28, 1919.
Application filed June 27, 1918. Serial No. 242,200.
To all whom it may concern:
Be it known that I, CHARLES L. Daromann, a citizen'of the United States, residing in the borough of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Watchcases, &c., of which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.
In Letters Patent of the United-States N 0. 1,268,821 dated June 11, 1918, there is shown and described an improvement 'in watchcases which is intended and adapted to make them waterproof for a long period of time, that is, to provide means for effectually preventing the entrance'of water between the members of the case, such as the center and the back and the center and the bezel. In accordance with the invention described in said Letters Patent there is provided between the proximate faces of the separable members of a watchcase an annular packing ring saturated with a water-repellent and a seat for such packing ring which has a space or recess for the reception of surplus saturant, so that the packin material shall remain always in a saturate and resilient condition and shall not become dry or hard as to its contacting face with the. lapse of time. The object of the present invention is to improve further the provisions for the storage of surplus saturant, espe' cially in watc cases in which, as ordinarll both the back and the bezel are separable from the center which is inter osedbetwen them. In accordance with his invention, instead of forming the recess for surplus saturant as an annular groove, it is pro osed to form apertures through the watcicase center, communicating on each side with the seats for the packing rings on the o posite faces of such center, thereby not. on y providing greater storage capacity for surplus saturant than is practical y possible by the formation of grooves, but roviding also for the passage of satu'rant romi the packing ring on one side of the center to the packing ring on the other side so that the saturant will at all times be equally distributed between the two packing rings, notwithstanding the fact: that one of said packing rings may be exposed more frequently than they other, as, for example, through the more frequent removal of the bezel or the back of the case and notwithstanding the fact that there may bea difference in the quality of the two packing rings. The invention will be more fullyexplained hereinafter with reference to the accompanying drawing in which it is illustrated and in which Figure 1 is a face view of a watch to .which the invention may be applied.
Fig. 2 is a face view, on a. lar er scale, of the watchcase center constructec in accordance with the invention.
Fig.3 is a detail view in section on the plane indicated by the broken line 33 of i 1, but on a larger scale.
11 the embodiment of the invention illustrated in the drawing the back band the bezel 0 have respectively, as indicated at b and c, a screw-threaded engagement with the center a. The back?) and the bezel cmay also be formed, as at b and 0 respectively, with an annular seat'adapted to receive a ring (Z of suitable backing material. The center a is also provided, on each side, with an annular seat a to receive the correspondin ring (Z of packing material, each seat being preferably dove-tailed so as to retain the packing ring in place when the back or bezel, as the case may be, is removed. In the web a between the two faces of( the center are formed, at suitable intervals, apertures or which extend from face to face of the web. These apertures may be of substantial size and they form, therefore, ample storage space for the surplus of the saturant with an annular seat for packing material storage space for surplus s'aturant and to between proximate faces of the separable permit the saturant to pass from one side members and with saturated packing beof the web to the other. tween the proximate faces, the web of the This specification signed this 24th day 10 5 center, between the seats for the packing, of June, A.'D. 1918. p
being formed with apertures to constitute CHAS. L. DEPOLLIER.
