Definitions

  • the back or bezel of the watch has a screw-threaded enagement with the watchcase center, as has n known heretofore, and is not only prov vided with a packing between the proximate faces but is constructed so as to have as well a smooth contact of metal to metal.
  • Furf thermore the construction is such that there watches has become much more agreeent and the fact that the demand still to the accompanyingdrawing in which it isillustrated in several different but practical embodiments and in which,-
  • FIG. 1 is a view in front elevation of a Watch embodying the invention. ⁇
  • Figs. 2, 3, 4, 5, 6, 7 and 8 are detail views in section and on a larger scale than Fig. 1, showing different embodiments of the invention.
  • the invention is illustrated, in its several embodiments, as applied to a watch which has the usual center a, the usual back b, and the usual bezel c, the back having a screwthreaded'engagement with the center as at b', and the bezel having a screw-threaded engagement with the center, as at c.
  • the center, back and bezel are formed so as to have continuous contact of their opposing faces, as at b2 and c2. All of these features of construction are known in the art and are common to the several embodiments of the invention illustrated and therefore need not be further described herein.
  • a recess a', a2 is formed in each face. of the center,
  • annular rib b3 or cs as the case may be, to enter the annular recess aor a2.
  • annular strip of packing material d Between the two opposing members is laid an annular strip of packing material d, which is ressed into the annular recess by the annu ar rib.
  • the annular rib in this case does not conform to the annular groove in the opposing member but leaves a recessor chamber a, for the reception and storage of a surplus of the water-repellent liquid with which the packing is saturated.
  • the packing 1s shown as a relatively thin but l road strip which is pressed into the rectangular groove a2 and is subjected to pressure along three lines, namely, the line of the apex of the rib c9 and the two lines formed by the angular shoulders of the groove a. Between these lines of contact the packing is preferably free from pressure and therefore retains its softness and resilience. Also that the space a3 for the reception of the surplus liquid is covered by the packing so that, when the watchcase is opened, the surplus liquid is not likely to be lost.
  • the proximate faces of opposing parts of the case are slightly beveled, so as to secure a contact at b2 and c2 as nearly perfect as possible, and such beveling leaves a space or chamber a4 in which surplus liquid might be received, but such surplus liquid in the space or chamber a'i lis likely to be wipedv off when the watchcase is open and therefore is not retained to saturate the packing. It is .therefore desirable that the storage space for the liquid be covered by the packing, as suggested.
  • one of the opposing members 1s formed with an annular recess a or a2, in this instance triangular in cross-section, which receives a packing strip.
  • the recess or chamber for the reception of surplus saturant is formed as at a? so as to bel covered by the acking material, such recess or chamberb so as to retain a substantial quantity of the saturant.
  • annular recess a or a2 is rec tangular in cross-section, a recess ax is formed in the bottom thereof, so as to be covered by the packing strip cl2, and another chamberfor the storage of surplus saturant may be formed as at b4 or c4 in the annular rib Zr? or c3.
  • annular chamber a' a, rectangular in cross-section, formed in the center a, and partly in an an- It will be observed eing annular nular chamber formed in the corresponding part of the case.
  • Annular recesses for the reception of the 'saturant may be formed at a5 in the center and at b5 and c in the back and bezel respectively, being covered by the packing.
  • the construction shown in Fig. 6 is substantially like that shown in Fig. 3, the packing d being received in an annular groove a', a2, rectangular in cross-section, formed in the corresponding side of the center a, and the annular recess for the surplus saturant being formed at a so as to be covered by the packing.
  • Fi 7 The construction shown in Fi 7 is generally similar to that shown in ig. 5, the packing strip d? being seated in annular grooves formed partly in each of the opposing members of the case.
  • the chamber for the surplus saturant while formed between the packing and the proximate face of one of the watchcase members, and covered and protected by the packing, is formed, as indicated at d", by holding the packing d so that it shall have a concave face next the adjacent case member.
  • the screw-threaded portions b and c are located between the packing or sealing device and the center ofA the watch, whereas in the construction shown in Fig. 8 the screw-threaded portions c* and bx are located between the packing or sealing device d8 and the circumference of the Watchcase.
  • the packing or sealing device is the same as already: described with respect to Fig. 5.
