The present inhention'consists in applying about and around the standing collar, surrounding the windin garbor or centre-square which moves the hands, or both of a watch-movement, fol-instance, of that class known as the Americanfl an adjustable-grooved collar, baring a suitable packing-medium to form a tight and close joint, when the watch is shut, with the case. thereof, and thus exclude or 'prevent the entrance of dirt to the "interior-.01 running-mechanism 0t the movement. 4
In the accompanying plate of drawings my improvements in watches are illustrated-s c Figure 1 being a view of a watchwith its back cover open, exposing the backplate', Figures 2, 3, 4,5, 6, Land 8, detail views of the packingwollar, showing difl'erent forms. A,in the drawings, represents the'windiug-post of a watch, projecting fromthe back-plate Bto the case, and there surrounded by astationary collar or-cup, G, fixed to the plate B. D is a collar, arranged to fit tightly over the outside of the cup 0. I i.
This collar Dis grooved around its -'upp erside, and in such groove is inserted a leather, cloth, or other packing-ring or washer, a, suitable to pack and form a close and tight joint to the entrance of dirt around the winding-post cup and the'back-cover, when such cover is closed. i
A packing-ring or collar, similar to that above described, may be also used upoh and around the centre- 1 square, which carries the hands, if so desired.
I claim as new,.and desire'to-secure by Letters Patent The adjustable collar D, containing the packing in the annular recess a, in combination with the back-plate B, cap C, and post A, of an ordinary watch, as .herein described, for the purpose specified.
