Definitions

  • Another object of this invention is the provision of an annunciator in which dark areas between lighting units are eliminated, so that a large area can be evenly illuminated.
  • a further object of the present invention is the provision of an annunciator constructed so that the indicating window is not heated.
  • a still further object of the invention is the provision of an annunciator in which indicia can be used in the form of photographic film without danger of deterioration of the emulsion.
  • the invention consists of an annunciator having a housing with a front panel formed with a plurality of apertures.
  • a translucent element covers each aperture and a plate is mounted on the rear surface of the panel in spaced, parallel relationship thereto.
  • a box lies behind each aperture between the panel and the plate. Matching apertures are provided on the plate and the box and a lamp is mounted in each set of matching apertures.
  • FIG. 1 is a front elevational view of an annunciator embodying the principles of the present invention
  • FIG. 2 is a rear elevational view of the annunciator
  • FIG. 3 is a plan view of the annunciator
  • FIG. 4 is a sectional view of the annunciator taken on the line IV-IV of FIG. 3, and
  • FIG. 5 is a vertical sectional view of the annunciator taken on the line V-V of FIG. 4.
  • FIG. 1 which best shows the general features of the invention, the annunciator, indicated generally by the reference numeral 10, is shown mounted on a wall 11. Lying forwardly of the wall 11 and larger than the aperture in the wall is a front panel 12. The panel is provided with two rectangular apertures 13 and 14. In the aperture 13 is carried a plate 15 on which is mounted a keyoperated switch 16 and a pushbutton switch 17; also carried in the aperture 13 is an indicating element 18.
  • indicating elements 19, 21, 22, and 23 bearing indicia indicative of remote stations ZONE 1, ZONE 2, ZONE 3, and ZONE 4, respectively.
  • a key-operated lock 24 for connecting it to an outlet box, not shown, mounted in the wall.
  • FIG. 2 it can be seen that a plate 25 is mounted rearwardly of the panel 12 and carries eight lamps 26, each of which is connected by wires into a cable 27.
  • FIG. 3 shows that the plate 25 is located spaced from and parallel to the front panel 12. It is held in that position by four posts 28. Between the panel and the plate lie cells 29, one associated with each of the lamps 26. On the rear surface of the front panel is carried a frame 31 for carrying window elements, as will be explained further hereinafter.
  • the cell 29 is a one-piece sheet metal stamping of square cross-section with the open side facing toward the panel 12.
  • the inner surface is provided with a reflective coating, such as white baked enamel.
  • the back wall of the cell is provided with a rectangular aperture 32, while the plate 25 is provided with a matching aperture 33 through which the lamp 26 extends.
  • Each lamp is of the incandescent type and has a body which fits exactly in the apertures 32 and 33; from each side of the body extend protuberances 34 which lock the lamp 26, cell 29, and plate 25 together tightly.
  • a window 35 consisting of a lamination of a clear plexiglas sheet 36, an indiciabearing sheet 37, and a white opaque plexiglas sheet 38.
  • the sheet 37 is, in the preferred embodiment, a photographic film in black-and-white carrying in its emulsion black lettering forming the various indicia, i.e., ZONE 1, etc., and a black background outlining the indicating elements 19, 21, 22, and 23.
  • the open end of each cell 29 lies a substantial distance from the rear surface of the window 35 (that is to say, the rear surface of the sheet 38).
  • An annunciator comprising:
  • a plate mounted at the rear of the panel in spaced, parallel relationship thereto and having an aperture corresponding to each aperture in the panel
  • each box lying behind certain of the apertures between the panel and the plate, each box being an open-sided cell, the edge of the open side lying a substantial distance from the translucent element, and
  • the translucent element is a sandwich formed of a layer of transparent plexiglas and a layer of colored plexiglas with a film which carries indicia interposed between the layers.
  • each box consists of an integral stamping whose inner surface is provided with a reflective coating.
