Abstract
Abstract An electric lamp has a base formed of two half sections made of insulating material. The base is aligned on and attached to the lamp by positioning the half sections on contact prongs, and by holding the two halves together through the action of a holding means such as a screw and nut or rivet with the screw or rivet extending through the interior of both half sections of the base, and the method of assembling the base to the lamp.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
An electric lamp comprising a glass envelope, an energy translation device connected to lead-in conductors which are hermetically sealed to said envelope, wherein the improvement comprises a base structure comprising contact prongs attached to the lead-in conductors and extending away from said lead-in conductors in both directions, said contact prongs comprising socket prongs at one end and a predetermined length extended away from said lead-in conductor at the other end, and two base sections made of insulating material, one of said base sections containing a hole and at least one alignment slot for receiving at least one of said predetermined lengths of said contact prong, said alignment slot formed as an indentation in the wall of said first base section, said alignment slot not extending through the wall of said first base section, said other base section containing two through openings for receiving said contact prongs and a hole in alignment with the hole of said first base section, said holes adapted to receiving a clamping means, and a clamping means inserted in and through said holes to firmly hold said base sections together.
Claim 2
Dependent Claim
184 words
An electric lamp comprising a glass envelope, an energy translation device connected to lead-in conductors which are hermetically sealed to said envelope, wherein the improvement comprises a base structure comprising contact prongs attached to the lead-in conductors and extending away from said lead-in conductors in both directions, said contact prongs comprising socket prongs at one end and a predetermined length extended away from said lead-in conductor at the other end, and two base sections made of insulating material, one of said base sections containing a hole and at least one alignment slot for receiving at least one of said predetermined lengths of said contact prong, said alignment slot formed as an indentation in the wall of said first base section, said alignment slot not extending through the wall of said first base section, said other base section containing two through openings for receiving said contact prongs and a hole in alignment with the hole of said first base section, said holes adapted to receiving a clamping means, and a clamping means inserted in and through said holes to firmly hold said base sections together.
Claim 3
Dependent Claim
18 words
An electric lamp as claimed in claim 1 wherein said clamping means is a screw and a nut.
Claim 4
Dependent Claim
15 words
An electric lamp as claimed in claim 1 wherein said clamping means is a rivet.
Claim 5
Dependent Claim
29 words
An electric lamp as claimed in claim 1 wherein a portion of said predetermined lengths is cut and bent around and attached to a part of the lead-in conductor.
Claim 6
Dependent Claim
