Definitions

  • My invention relates to electric incandescent lamps and similar devices comprising a bulb, a filament and a base, and more particularly to improvements in methods of manufacture thereof having as their object the production of devices having the said parts in more uniformly accurate relation and alignment.
  • my invention consists in the production of a bulb having a neck portion which has a portion thereof formed definitely so that when a base is subsequently seated over said portion it will be axially aligned with the bulb and spaced a definite distance from the filament. Moreover, according to my invention, the sealing 2U of the mount in said bulb is so accomplished that the seating portion of said neck is substantially retained.
  • FIG. 1 is an elevation of a bulb formed according to my invention
  • Fig. 3 is a similar view of an old form of bulb
  • Figs. 4 and 5 are views showing cases of faulty alignment arising from the use of said old form
  • Fig. 6 is an elevation of 3U a lamp embodying my invention equipped with a bayonet type base.
  • the bulb shown in Fig. 1 is blown with a bowl portion 10 and a neck portion 11. At their junction there, is a comparatively sharp 3.3 contraction resulting in a shoulder 12 and below said shoulder the constricted portion A is definitely dimensioned and shaped for a short distance to conform to the kend' portion of a base shell.
  • the base is so positioned that the ins 18 are accurately positioned -a definite istance from the filament of the lamp on account of the engagement of the end of the base with the shoulder.
  • the base of the filament is indicated at 00.
  • Fig. 3 In Fig. 3 is shown the old form of bulb. The absence of a shoulder such as 12 of Fig. 65 1 and of the portion A immediately therebelow renders accurate sealing-in difficult. The result is that the sealing-in operation causes an irregular shoulder to be formed on the bulb neck, as shown at 19-20 in Fig. 4, and 70 21-22 in Fig. 5.
  • the bases When the bases are slipped, over the end of such bulbs they are not properly aligned with the bulb or filament and not only present an unattractive appearance but render the definite positioning of a fila- Vthereloelow and conforming totheinterior end portion ofthe base, sealing-infthe filarnent mount while preserving a substantial part of said base seating portion, and then positioning the base with the end portion thereof engaging said base seating portion and uniting the base to said bulb.
  • An incandescent lamp comprising a fila-- ment, a bulb comprising a neck having a shoulder and a portion extending a substantial distance therebelow and accurately disposed axially with reference to said filament and a base comprising an end portion having an inner surface conforming to the surface of said neck portion and seated thereon.
