Definitions

  • This invention relates to a tight winding device for time pieces which comprises a crown having a packing adapted to form a tight joint about the pendant neck of the watch-case.
  • the invention primarily consists in that this packing presents a main body provided with an external flange, said main body being lodged with play in an annular recess of the crown while said liange is compressed between a shoulder of the crown and a clamping piece borne by the crown.
  • I designates the case body, 2 the pendant neck and 3 the winding crown in which there is lodged a packing 4 adapted for use as a tight joint about the pendant neck 2.
  • This packing is formed of a cylindrical main body IlEL and a flange 4b projecting externally from the periphery and at the lower portion of the main body.
  • the main body 4a is lodged with play in an annular recess 5 of the crown while the ange 4b is compressed between a shoulder E of this crown and a clamping ring 1 set in the lower portion thereof.
  • the flange is made integral with the body of the packing.
  • the flange is constituted of an annular projection of the packing body and a metallic washer 4d Xed on this projection.
  • the iiange only consists in a metallic washer 4e partly engaged in a peripheral groove of the packing body.
  • a tight winding device for time pieces the combination with a case body having a pendant neck Xed thereto, of a crown having an annular recess, a compressible packing tted about said neck and including a cylindrical main body spaced radially from the side wall of said recess and a lower flange projecting outwardly from the periphery of said main body, said main body having sealing contact with said pendant neck, a shoulder on the outer wall of said ⁇ recess and a clamping piece borne-by said crown, said llange of the packing being compressed between and having sealing Contact with said shoulder and said clamping piece.
  • a tight winding device as claimed in claim i, wherein the flange comprises an annular projection of the main body and a metallic washer fixed on said projection.
