Definitions

  • Our invention relates to electric lamps and similar devices, and more particularly to the base portions of such devices.
  • the principal object of our invention is to provide a base which does not 6 require cementing to the bulb of the lamp 'or other device.
  • a contact carryinginsulating cap is provided which is frictionally held by the neck portions of the bulb.
  • the latter is preferably shaped to engage a retaining element such as a screw-threaided shell carried by the socket.
  • leading-in wire 12 passes through the'hollowed out interior of a cap 19 to a metal insert 20 in the end thereof to which it is soldered and the correspondingend of leading-in wire 13 passes between the cap and the hollow interior of the stem to a position between metal insert 21 in the'canand stem flange .17.
  • Both metal inserts and 21 are molded into the cap which is made from an insulating material such as hard rubber.
  • the cap is fastened to the bulb lopreferably by a plurality of fingers 22 and 28 which fit into correspondingly shaped depressions in the neck of the bulb and over protuberances 24 therein. The fingers are resilient and tend to spring inward so that they hold the cap very securely and prevent it from being easily turned or pulled off.
  • the outer portion 25 of the bulb neck between the fingers has the screw thread contour similar to that of the metal Edison or screw base andis designed to engagethe threads of a socket. when inserted into such a socket, electrical contact is made by the engagement of insert 20 with the center contact of'the socket and of those portions of the 'flngers 22 and 23 over protuberances 24 with the threaded socket shell.
  • FIG. 1 is a 'per'spect've view of an incandescent lamp embodying the improved.
  • a bulb having leading-in wires extending from the neck portion thereof, and an insulating cap fitting in the end of said neck portion and carrying a center contact and side straps of resilient conductive material engaging the outer surface of said neck, said center contact and at least one of said side straps being electrically connected-to a leading-in wire, the outer surface of said bulb neck being shaped to engage a retaining grooves for receiving said straps.
