Definitions

  • My invention relates to bases for electric incandescent lamps and similar devices. More par-. ticularly my invention relates to such devices having bases which are comprised of insulating 5 material molded directly thereon and are provided with metallic contact areas or terminals.
  • FIG. 1 is a perspective view of b
  • FIG. 5 is a perspective view of another species of my invention
  • Figs. 6, 8 and 10 are vertical sections through a portion of still other species of my invention
  • Figs. '7, 9 and 11 are horizontal sections along lines 66, 8-8, and Ill-l ll respectively of the species shown in Figs. 6, 8 and 10.
  • the base comprises collar Ill and a substantially cylindrical portion II with oppositely disposed lateral ridges l2 extending longitudinally thereof.
  • these portions are all formed from the molded material which is preferably composed principally of a synthetic resin, a hardening compound and a filler such as marble flour or the like.
  • a synthetic resin such as Bakelite.
  • One such synthetic resin is commercially known as Durite which is a furfural or phenol formaldehyde product. This substance is preferred for its resistance are contact areas or terminals l3'c0nnected to a hardening compound such as hexamethylenefilament H and, in the species shown in Fig.
  • Fig. 1 My method of molding the species shown in Fig. 1 consists, as shown in Figs. 3 and 4, in first bending the outer ends is of the leading-in wires into the form shown and placing the lamp in holder 28.
  • the holder is provided with a sponge rubber facing it so as to engage all portions of the irregular shaped bulb 22.
  • the mold 23 is then brought down into contact with the bulb in such a position that the leading-imwires will be properly placed in the mold whereupon the required amount of molding material is inserted into passage 26 and is pressed into all portions of the mold by plunger 25.
  • The'mold is now heated, preferably to 0., until the base material has taken a permanent set whereupon the bulb holder 2B is removed and the completed based lamp removed from the mold.
  • the base terminals are sections of the leading-in wires each of which is bent into the looped form shown. This provides the two oppositelydisposed terminals and serves also to resist displacement during the molding process.
  • inserts differs in that said wires are soldered or welded thereto before the base is molded.
  • the said enclosure and avbase consisting of an insulating substance molded on said enclosure and having embedded therein the ends of said lead wires, said base having at least one longitudinally extending protuberance at the side thereof formed from said insulating material and having a portion of one of saidlead wires exposed at the surface thereof to constitute a terminal.
  • An electrical device consisting of a glass enclosure having an electric energy translation element mounted therein and lead wires connected to said element and extending through the said enclosure and a base consisting of an insulating substance molded on said enclosure and having embedded. therein the ends 01 said lead wires, said base having at least one longitudinally extending protuberance at the side thereof formed from said insulating material and having a terminal body exposed at the surface thereof having electrical connection to one of said lead wires.
  • An electrical device consisting 01' a glass en closure having an electric energy translation element mounted therein and lead wires connected to said element and extending through the said enclosure and a cylindrical base consisting of enclosure having anelectric energy translation element mounted therein and lead wires, connected to said element andiextending through the said enclosure and a cylindrical base consisting of an insulating substance molded on said enclosure and having embedded therein the ends'of said lead wires, said base having at least one longitudinally extending ridge at the P side thereof formed from said insulating material.
  • An electrical device consisting of a glass enclosure having an'electric energy translation element mounted therein and lead wires.connected to said element and extending through said enclosure, and a base consisting of an insulating substance molded on said enclosure and having embedded therein the ends of said lead wires, said base having at least one longitudinaily extending protuberance at the side thereoi, and the embedded end of a lead wire being bent into an angular loop extending outward from the wall of said enclosure and having its midportion exposed at the surface of said protuberance to constitute a'terminal.
