Definitions

  • the present invention relates to electric lamps, and particularly to mounting means therefor.'
  • Fig. 1 is a sectional view showing a lamp supported in said mounting
  • Fig. 2 is a similar view showing the lamp reversed in vsaid mounting
  • Fig. 3 is an elevational view of the lamp and the permanently associated base member
  • Fig. 4 is a sectional view of the parts shown in Fig. 3, and
  • Fig. 5 is a bottom view of the base member shown in Fig. 3. i
  • a tubular base member 1 of bakeliteor any other suitable insulating material has kthe end of a lamp positioned therein.
  • This lamp can be of any type whatever, but as here shown consists of a cathode glow lamp 2 having the glow supporting electrodes 3, which are supported by the sealedin leads 4 and 5, extending beyond the tubular member 1.
  • Two contact strips 6, of brass or the like, are positioned in suitable grooves which extend from end to end of said member 1 at diametrically opposite points ir the exterior surface thereof, said stri s being firmly fixed in said slots in any suita le manner, as by shrinking the member 1 down onto said strips, or by forcing the strips into suitably undercut slots.
  • Each of these strips 6 has a bulge 7 formed therein at a point which is equidistant from the ends of the base mem' ber 1.
  • a recess 8 is formed in one side of the inner wall of the tubular member 1 at the opposite end from the lamp 2. This recess accommodates a resistance 9 which as shown consists of a piece of graphitized paper having spaced eyelets therein to which the electrical connections are made.
  • the lead 5 is attached to one of saideyelets, while a Wire 10 is connected to the other 0f said eyelets.
  • the lead 4 and said Wire 10 are led outwardly through suitable slots in the end of the tubular member 1 and of the contact strips 6, the ends thereof being soldered to said contact strips.
  • the remainingfspace within the tubularmember 1 is filled with sealing wax, resin, or any similar insulating material 11.
  • This sealingfwax or the like is poured into the tubular member 1 after the assembly is otherwise complete and serves to cement the lamp 2, resistance 9 and other elements into said tubular member, and at the same time seals the resistance 9 from all moisture.
  • the socket 12 of suitable insulating material, such as bakelite, fiber, porcelain, or the like has a central opening therein in which the tubular member 1 may be placed with one end thereof against the annular shoulder 13.
  • Contact springs 14 which are attached to the socket 12 extend through'suitable slots in said socket and engage the contact strips 6, said springs 14 being so shaped as to snap over the bulges 7 in said contact strips, and to thereby firmly hold said tubular member 1 against said lshoulder 13.
  • the tubular base member 1 Due to the symmetry of the tubular base member 1, and to the fact that the outside diameter thereof is greater than the largest diameter of the lamp 2, said member can be inserted in the socket 12 either with the lamp 2 extending above said socket, as shown in Fig. 1, or with the lamp extending therebelow, as shown in Fig. 2.
  • the s rings 14 hold the lamp firmly in place, so tiiat it cannot vibrate loose under any circumstances, yet the lamp 2 may be easily removed from the socket 12 and a new one inserted therein when desired. This new mounting is, therefore, extremely beneficial for use in all locations where severe vibrations are encountered.
  • a tubular lamp base member of insulating material having an outwardly extending bulge therein, an eccentric rece in the bore of said base member, a resistance in said recess, and a cementitious material within said bore, said material serving1 to hold said lamp in said base member an to seal said resistance against moisture.
  • a tubular lamp base member of insulating material having a tubular lamp base member of insulating material, an electric lamp bulb mounted therein, the greatest diameter of said lamp bulb being less than the outer diameter of said base member, and diametrically spaced contact strips extending lon itudmally along the outer surface of sai base member, the leads of said lamp bulb being connected to said contact strips, each of said strips having a bulge therein at a point midway between the ends of said base member.
  • a tubular lamp base member of insulating material having a bore therein of substantially the same diameter as said lamp base member, a shoulder at one end of said bore, and contact springs mounted on said socket and engaging the bulges on said contact strips whereby said lamp hase is held irmlv against said shoulder.
  • a tubular lamp base member of insulating material having a bore therethrough, a portion of said bore being of substantlally the same diameter as that of said lamp base member while another portion of said bore is of a diameter which is smaller than that of said lamp base member but larger than that of said lamp bulb, whereby said base member can be inserted with either end in said bore, and contact springs mounted on said socket member and engagin the bulges on said contact strips to hol said lamp base firmly in said socket.
