Definitions

  • Sw1tzerland 6165/70 formed of metal and possessing a Substantially circular cylindrical foot or stem to a dial, which comprises the 29/177 5 steps of forming an opening in the dial at the location [58] Fieid 509 intended to receive the applied chapter, this opening 29/558 1 5 possessing a non-circular cross-sectional configuration, with the smallest dimension thereof at least being as large as the diameter of the foot or stem of the applique [56] References Cited or applied chapter.
  • the stems are then inserted from the front face of the dial plate through corresponding likewise circular-cylindrical bores which have been previously formed at the dial plate.
  • the entire unit is then turned over and from the opposite face, in other words from the rear face of the dial plate, the excess length of each steam'or foot is then ground away, for instance by using a small grinder. Thereafter, the stems are riveted, again from the opposite or rear face of the dial plate.
  • a primary object of the present invention is to provide just such improved method for this purpose which is not associated with the aforementioned prior art drawbacks and fulfills the existing need in the art.
  • Another and more specific object of the present invention relates to a technique for attaching metallic applique or applied chapters, each equipped with a substantially circularcylindrical foot or stem to a dial in a manner safeguarding against rotation or undesired displacement of the applied chapters.
  • the invention contemplates providing the dial disc or plate with an opening at the location where it should receive the applique or applied chapter, this opening possessing a non-circular cross-sectional configuration, and the smallest dimension or extension thereof however at least being as large as the diameter of the stem or foot portion of the applied chapter.
  • This stem is then inserted into the opening, and thereafter the stem is deformed from the opposite side of the dial plate until it 5 assumes the shape of the opening in which it is housed.
  • FIGS. 1 and 2 respectively illustrate in section and plan view a first step of the inventive method
  • FIG. 3 is a sectional view of the dial disc or plate following a second method step of the invention.
  • FIGS. 4 and 5 are respective sectional and plan views of the dial plate of FIG. 3 with the inserted applique or applied chapter;
  • FIG. 6 is a sectional view of the dial plate together with the applied chapter secured thereto.
  • a recess 2 is stamped into the back or rear face of the dial disc or plate 1 at the location where later on the stem or leg 4 of an applique or applied chapter 5, the figure, typically an hour figure, is to be inserted.
  • a press punch or other suitable tool instead of stamping these recesses 2 one after the other, it would be possible to use a press punch or other suitable tool by means of which in a single working operation all of the required recesses needed for the attachment of the hour figures could be conjointly stamped, and if desired even a further recess at that location where, if necessary, there is desired a window for a date or calendar indicator.
  • recesses 2 possess a cross-sectional configuration which deviates from the circular-shape, for instance, in the illustrated embodiment conceptually such recesses may be considered to possess a square configuration or, if desired, a rectangular, oval or eliptical configuration. Owing to the nature of the stamping operation each recess will narrow somewhat towards its base, as best shown by referring to FIG. 1. The stamping operation is performed in a manner that the depth of the produced recesses 2 exceed the thickness of the dial plate or disc 1.
  • the second working operation resides in machining the opposite face of the dial plate or disc 1, and specifically the face which later will be the front face of the dial, and this can be done by means of a small grinding disc, wherein machining is undertaken such that the portions of the recess or recesses 2 which protrude past the surface of the dial plate 1 are removed. Consequently, as best seen by referring to FIG. 3 at the location of each recess 2 there is now present an opening 3, the cross-section of which corresponds to that of the previous recess, and again as best seen by referring to FIG. 3, narrows in the direction of the opposite face of dial plate 1.
  • the next working operation entails turning over the dial plate or disc 1 and, if desired, after finishing the front face of the dial plate, inserting into each opening 3 produced in this manner the circular-cylindrical stem or foot 4 of the applique or applied chapter 5 formed of metal.
  • the dimensions of the recesses 2 which form the individual openings 3 care was taken to ensure that the smallest dimension or extension of each such opening at least was as large as the diameter of the stem or foot 4 of the inserted applique chapter.
  • the last operational step resides in deforming the stems or feet 4 of the chapters 5, during such time as the latter are held in their desired position upon the dial plate 1, from the rear face of such dial plate in such a way that the material of each stem 4 during deformation tends to fill-out the cross-section of the associated opening 3, thereby assuming the shape or configuration of such associated opening.
  • This deformation of the material of each stem or foot 4 of each applique chapter 5 can be undertaken by crushing such stem or by subjecting it to the action of ultrasonic energy.
  • the applique or applied chapter 5 which has been attached in this manner can no longer rotate within its opening 3. Furthermore, as long as such opening 3, as depicted in the exemplary embodiment, widens towards the rear face of the dial plate 1, the chapter 5 at the same time can also not move in axial direction of its stem or foot 4 and therefore it is secured against dropping out of the associated opening.
  • a method for making a dial plate with attached applique or applied chapters comprising the steps of:
  • each said opening possesses a substantially square crosssectional configuration.
  • each said opening possesses a substantially rectangular cross-sectional configuration.
  • each said opening possesses a substantially oval crosssectional configuration.
  • each said opening possesses a substantially eliptical crosssectional configuration.
