Abstract
Abstract An electric light holder having a base and a socket to receive a bulb. The socket is removably held to the base by a pair of outwardly extending opposed plastic wings at the front of the base which snap into grooves at the sides of the socket. The wings also serve as stops for the rear of a reflector which is slid over the socket and held in place against the wings by a retainer ring threaded over the socket. Alternatively the reflector can be suspended from the wings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
226 words
An electric light holder comprising: (a) a base having a forward end, (b) a pair of wings projecting laterally outwardly in substantially opposed directions from said forward end, (c) a socket having a forward end for receiving an electric bulb and having a rear end, (d) said socket having an outer surface and a pair of grooves in said outer surface, said grooves being spaced apart from each other around said outer surface and each having a predetermined width, (e) detent means in each groove, (f) said wings each being of thickness less than the width of said grooves, said wings having inner ends defining therebetween a space for the rear end of said socket to be placed between said inner ends with said inner ends located one in each groove, (g) said inner ends of said wings each including retaining means cooperating with said detent means of said grooves to releasibly secure said socket to said base, said wings being of a flexible material so that they can be flexed to release said retaining means of said wings from said detent means of said grooves, (h) said outer surface of said socket having ring retaining means thereon, (i) and a retainer ring adapted to be mounted on said ring retaining means to secure a reflector over said socket between said retainer ring and said wings.
Claim 2
Dependent Claim
226 words
An electric light holder comprising: (a) a base having a forward end, (b) a pair of wings projecting laterally outwardly in substantially opposed directions from said forward end, (c) a socket having a forward end for receiving an electric bulb and having a rear end, (d) said socket having an outer surface and a pair of grooves in said outer surface, said grooves being spaced apart from each other around said outer surface and each having a predetermined width, (e) detent means in each groove, (f) said wings each being of thickness less than the width of said grooves, said wings having inner ends defining therebetween a space for the rear end of said socket to be placed between said inner ends with said inner ends located one in each groove, (g) said inner ends of said wings each including retaining means cooperating with said detent means of said grooves to releasibly secure said socket to said base, said wings being of a flexible material so that they can be flexed to release said retaining means of said wings from said detent means of said grooves, (h) said outer surface of said socket having ring retaining means thereon, (i) and a retainer ring adapted to be mounted on said ring retaining means to secure a reflector over said socket between said retainer ring and said wings.
Claim 3
Dependent Claim
40 words
An electric light holder according to claim 1 wherein said wings and said grooves are each two in number, said wings being spaced 180 degrees apart around said base and said grooves being spaced 180 degrees apart around said socket.
Claim 4
Dependent Claim
20 words
An electric light holder according to claim 2 wherein said grooves extend substantially to said rear end of said socket.
Claim 5
Dependent Claim
33 words
An electric light holder according to claim 1 wherein said ring retaining means is a screw thread extending around the outer surface of said socket, said screw thread being discontinuous at said grooves.
Claim 6
Dependent Claim
34 words
An electric light holder according to claim 1 wherein said base has a central longitudinal axis, and said wings have forward surfaces which together define a plane extending at right angles to said axis.
Claim 7
Dependent Claim
48 words
An electric light holder according to claim 1 wherein each wing has a forward surface and an inner surface, said retaining means of each wing comprising a formation which slopes rearwardly and radially inwardly from said forward surface and terminates in a rearward facing and radially extending wall.
Claim 8
Dependent Claim
49 words
An electric light holder according to claim 6 wherein said detent means of each groove comprises a ridge extending laterally across each groove adjacent the rear end of said groove, said ridge having a radially oriented forward surface and an outer surface which slopes rearwardly and radially inwardly therefrom.
Claim 9
Dependent Claim
76 words
The electric light holder according to claim 1 wherein said wings are generally triangular in shape as viewed from the side, each having a forward surface, a radially inner surface and an outer surface which slopes forwardly and radially outwardly from said base to the outer edge of said forward surface, said outer surface defining at the outer edge of each wing a substantially flat radially outwardly directed surface on which a reflector may be hung.
Claim 10
Dependent Claim
85 words
An electric light holder according to claim 1 wherein said base has a central longitudinal axis, and said wings have forward surfaces which together define a plane extending at right angles to said axis, said holder further including a reflector, said reflector having a rear flat surface having an opening therein, said opening being dimensioned to fit over said socket so that said rear flat surface may be pressed against the forward surfaces of said wings and held in place thereon by said retainer ring.
Claim 11
Dependent Claim
56 words
An electric light holder according to claim 1 wherein said socket includes a substantially U-shaped retainer spring to retain an electric bulb therein, said retainer spring having a pair of legs and tabs extending outwardly from said legs, said grooves each having a bottom wall having an opening therein to accommodate and retain a said tab.
Claim 12
Dependent Claim
68 words
An electric light holder according to claim 1 wherein said socket includes a main receptacle to accommodate the bottom of said electric bulb, a pair of pin receptacles one at each side of said main receptacle, said grooves being two in number and being spaced 180 degrees apart around said outer surface of said socket, each pin receptacle being spaced 90 degrees around said socket from each groove.
Claim 13
Dependent Claim
81 words
An electric light holder according to claim 1 wherein said base is of molded plastic and is substantially cylindrical in form, having an interior wall, and wherein said socket is of molded plastic and includes a plurality of plastic guide members projecting rearwardly therefrom, said guide members having outer surfaces and being dimensioned to fit within said base with the outer surfaces of said guide members pressed against the inner wall of said base, to align said socket with said base.
