Definitions

  • timepiece dials of this type in which the time indicia are obtained by injecting liquid plastic material directly on the plate of the dial which is placed in a mould.
  • the tooling necessary for carrying out such a process is costly and a new mould must be especially made for each type of dial.
  • the carrying out of such a process is delicate, especially when it is desired to make curved dials.
  • FIGURE 1 is a cross-sectional view of a dial with a time sign postioned thereon but not secured thereto.
  • FIGURE 2 is across-sectional view of the dial with the time sign secured.
  • FIGURE 3 is a cross-sectional view of a second modification of the invention taken along lines III-III of FIGURES 4 and 5.
  • FIGURES 4 and 5 are side views of the back of the dial in a second embodiment of the invention.
  • FIGURE 6 is a cross-sectional view of another modification.
  • FIGURE 7 is a schematic view of apparatus intended for use in the attaching of time indicia according to the invention.
  • FIGURE 8 is a cross-sectional view VIII- VIII of FIGURE 7.
  • FIGURE 1 shows a dial plate 1 perced by openings 2 and 3 through which pass the feet 4 and 5 of a sign in relief 6. The length of the feet exceeds slightly the thickness of the dial plate 1.
  • sign 6 can be secured by means of a single foot shown on FIGURE 3.
  • the foot can fbe advantageously given a cross-sectional shape other than circular, for example, square as shown on FIGURE 4.
  • the shape of the crosssection will permit to exactly position the time sign, the
  • the foot can also be given a crcular cross-section as shown in FIGURE 5 by positioning the sign in an imprint presenting the negative of the back of the dial or by any other means.
  • FIGURES 8 and 9 show by way of example a device for carrying out this process wherein members 8 are integral with a common support 11 containing electrical resistance 12.
  • the source of heat naturally can be of another nature, ultra-sonic or chemical for example.
  • the process according to the invention is not limited to the securing of time signs on finished or unfinished dials, but can also be used for attaching any other elements on the dials, such as a ring, segment, circle, Symbol, trademark or other decorative element.
  • plastic materials can be used in the practice of the claimed invention and the temperatures at which the process will be carried out will depend on the softening point of these plastic materials, all of which are well known to those skilled in the art.
  • suitable plastic materials there may be used polystyrene, polyethylene, epoxy resins, and in general any hard plastic resinous materials having an appreciable resistance to wear and which can be softened at a reasonably low temperature.
  • the plastic material constituting the time indicia can be metallized or can have incorporated therein various colouring agents so as to give them the desired colour.
  • a timepiece dial comprising a dial plate of a given thickness and having a plurality of openings therein, said openings having rugosities in the walls thereof, said openings being postioned in areas where time signs are desired, a plastic time sign sitting over each of said openings, said time sign having at least one projection sitting in said opening and fused to ⁇ said rugosities in said opening.
  • Dial according to claim 4 wherein said time signs 1,436,058 are metallized. 74,040 6. Dial according to claim 4, wheren said time signs 320,002. contain coloring agents. 340,448 References Cited 5 353'682 UNITED STATES PATENTS 3,277,562 10/ 1966 Huguenin 29-177 FOREIGN PATENTS RICHARD B.
