Abstract:
1. An electric lamp socket comprising: a base formed from a pressed metal cup and a round metal nut, wherein the pressed metal cup has a wide top defining a rim and a narrow bottom defining a hole and wherein the pressed metal cup defines a first shoulder positioned between the wide top and the narrow bottom and wherein a first side wall of the metal cup is substantially vertical from the rim to the first shoulder, then narrows at the first shoulder to form a bevel along an outer surface of the first side wall, and then curves inward toward the narrow bottom of the metal cup, wherein the first side wall defines a first slot extending down from the rim, and wherein the round metal nut is a substantially hollow cylinder having a top and a bottom, wherein the substantially hollow cylinder has threads through its hollow interior from the top to the bottom, and wherein a pair of flanges extend up from the top of the substantially hollow cylinder and pass through the hole in the narrow bottom of the pressed metal cup and wherein the flanges are pressed apart to attach the round metal nut to the pressed metal cup; a body having a substantially cylindrical shape and formed of pressed metal, wherein the body has a round top, a round bottom, a second shoulder approximately midway between the round top and the round bottom and a band of threads proximate the round bottom, and wherein a second side wall formed from a single piece of pressed metal extends from the round top to the round bottom of the body, wherein a portion of the second side wall extending from the round top to the second shoulder is substantially vertical, wherein the second side wall widens at the second shoulder, and wherein a portion of the second side wall extending from the second shoulder to the band of threads is substantially vertical, and wherein the second side wall widens at the band of threads so that an inner diameter of the body taken at the band of threads is greater than an outer diameter of the base taken at the rim and wherein an inner diameter of the body taken above the band of threads and below the second shoulder is less than or equal to the outer diameter of the base taken at the rim, wherein the body further defines a second vertical slot extending from the round bottom through the band of threads and through a portion of the second side wall below the second shoulder and wherein a dimple is punched inward through the band of threads, and wherein the body is placed over the base so that the band of threads on the body substantially surround a portion of the base from the rim to the first shoulder and wherein the dimple in the body aligns with and engages the first slot so that the band of threads is prevented from turning around the portion of the base from the rim to the first shoulder; and a ring nut having a top and a bottom and a threaded interior wall extending from the top to the bottom wherein the top and the threaded interior wall are sized to engage the band of threads on the body and wherein the bottom narrows so that a diameter taken across a hole defined by the bottom of the ring nut is less than a diameter taken across the rim of the base so that when the ring nut engages the band of threads on the body and is tightened, the bottom of the ring nut presses upward against the first shoulder and wherein the rim of the base presses up against the portion of the second side wall of the body extending from the second shoulder to the band of threads.
