Definitions

  • My invention relates to improvements in incandescent lamps, and more particularly in the construction of the base carrying the bulb.
  • The'object of the improvements is to provide an incandescent lampin which the base is not subject to corrosion by acid and other gases such as are produced in chemical laboratories, factories, and the like, and with this object in view my invention consists in constructing the base of materials which are not affected by acids and atmospheric influences.
  • the current conduct ing elements may be composed of a suitable non-corrosive metal such as stainless steel. or metal alloys capable of resisting acids and atmospheric influences, such as silicon steel.
  • a suitable non-corrosive metal such as stainless steel.
  • metal alloys capable of resisting acids and atmospheric influences such as silicon steel.
  • the base of the lamp comprises an outer substantially cylindrical current conducting member composed of a suitable non-corrosive metal or carbon material and formed with the usual screw threads 6 for fitting in a holder of normal construction, and an inner current conducting member in the form of a tapering elongated block likewise composed of a suitmembers a and I) while in plastic form and allowed to set into a hard body.
  • the members a and b constitute the terminals of the lamp, and have the leading-in wires f and 9 connected thereto.
  • the terminals a and b may, when composed of carbonmaterial, be provided with a metal coating on a portion of their inner surfaces, and the leading-in wires soldered to such coating.
  • An incandescent electric lamp comprising a bulb, and a base having an outer cylindrical current terminal composed of acid roof material and adapted to be inserted in a holder, an inner current terminal composed of acid proof material and mounted concentrically of said outer terminal and an insulating'body disposed between said terminals.
  • An incandescent electric lamp as set forth in claim 1 having outer and inner terminals composed of carbon.
