Definitions

  • Still another object of my invention is the provision of a filament mount structure which will permit the coiled filament to be readily and positively fastened thereto on high speed machines serving for mass production.
  • Fig. 1 is a side elevation of an electric miniature lamp comprising my invention
  • Fig. 2 is a front elevation, partly in section, of the lamp' shown in Fig. 1, the view being taken at ninety degrees to that of Fig. 1
  • Fig. 3 is an en- I larged perspective view of the filament mount structure and associated coiled filament, showing the manner in which the latter is fastened to the two lead wires.
  • the two lead wires which support and supply current to the coiled filament are, according to the invention, bent above the glass bead at an appreciable angle, and perpendicular to the center plane of the lamp passing through the unbent portions of the two lead wires.
  • the upper ends of the two lead wires are bent back towards the said center plane and substantially perpendicular thereto, and are formed with hooks at the ends thereof, which hooks are disposed within and at right angles to the said center plane.
  • the ends of the coiled filament, which is arranged in this same center plane are clamped in these hooks.
  • the lamp comprises a spherical glass bulb I, the filament l2, and the two current-supply or lead wires II, M, which are sealed in a glass bead l3 and which serve to support the filament.
  • the outer leads I5, I 5, which protrude from the neck l6 of the bulb, are soldered to the base sleeve l1 and to the bottom center contact l8 respectively, of the base.
  • the two inner lead wires l4, M are provided above the glass bead l3 with portions l9, l9 bent 'at an appreciable angle to the longitudinal axis of I 55 the lamp but perpendicular to the center plane of .the lamp passing through the unbent portions of the two inner lead wires ll, H.
  • the upper ends of the two inner lead wires are bent back towards the above-mentioned center plane to form the portions 20, 20, which extend substantially perpendicularly to said center plane;
  • the inner portions I9, l9 and 20, of the inner lead wires are preferably made to extend parallel to each other, and
  • the ends. of the portions 20, 20 are formed with horizontally disposed clamps or hooks 2
  • 2' of the filament l2, which extend longitudinally of the lamp, are inserted into the open hooks 2
  • is preferably selected in such a way that the filament will, at the same time, be symmetrically disposed with respect to' Y the center point of the lamp.
