Abstract
Abstract A light fixture comprising a housing having an opening intermediate oppositely facing walls to permit a lamp to be moved into and out of the interior of the housing. A closure is removably disposable across the opening to enclose the housing in weather-tight fashion. A sleeve on one of the oppositely facing walls of the housing receives an electrical socket for axial movement between retracted and extended positions. A means on the other of the oppositely facing walls provides a face of heat insulating and cushioning material for engaging the nonelectrical end of the lamp when the electrical end thereof is received within the socket. The face and sleeve are spaced apart a distance which permits the electrical end of the lamp to be moved into and out of the socket when the socket is retracted. A means is provided for positioning the socket in its extended position so as to hold the opposite, non-electrical end of the lamp against the face of heat insulating and cushioning material.

Claim 1
Independent Claim
165 words
A light fixture, comprising a housing having oppositely facing walls, an opening intermediate the oppositely facing walls to pass a lamp to and from the interior of the housing, and a closure removably disposable across the opening, an electrical socket for receiving the electrical end of the lamp, a sleeve on one of said oppositely facing walls to receive the socket for axial movement between retracted and extended positions with respect to said one oppositely facing wall, means on said other of said oppositely facing walls providing a face of heat insulating and cushioning material for engaging the opposite end of the lamp, said face and sleeve being spaced apart a distance which permits the electrical end of the lamp to be moved into and out of the socket when the socket is retracted, and means for positioning the socket in extended position so as to hold the opposite end of the lamp against said face when its electrical end is received in the socket.
Claim 2
Dependent Claim
165 words
A light fixture, comprising a housing having oppositely facing walls, an opening intermediate the oppositely facing walls to pass a lamp to and from the interior of the housing, and a closure removably disposable across the opening, an electrical socket for receiving the electrical end of the lamp, a sleeve on one of said oppositely facing walls to receive the socket for axial movement between retracted and extended positions with respect to said one oppositely facing wall, means on said other of said oppositely facing walls providing a face of heat insulating and cushioning material for engaging the opposite end of the lamp, said face and sleeve being spaced apart a distance which permits the electrical end of the lamp to be moved into and out of the socket when the socket is retracted, and means for positioning the socket in extended position so as to hold the opposite end of the lamp against said face when its electrical end is received in the socket.
Claim 3
Dependent Claim
65 words
A light fixture as described in claim 1, wherein said socket is relatively closely received within said sleeve, and the socket positioning means comprises a longitudinal slot in the sleeve, a screw on the side of the socket and extending through the slot for longitudinal movement therein, and a nut on the end of the screw for bearing on the outer side of the sleeve.
Claim 4
Dependent Claim
57 words
A light fixture as described in claim 1, including a reflector on the inner side of the one oppositely facing wall, said housing having a plurality of side walls intermediate said oppositely facing walls, and a window in each said side wall of the housing, one of said windows comprising said closure removably disposable over said opening.
Claim 5
Dependent Claim
194 words
A light fixture, comprising a housing having top and bottom walls, means on the bottom wall for mounting the housing on the upper end of a post, a window in the housing intermediate the top and bottom walls, and means removably connecting said window to the housing to permit a lamp to be passed into and out of the frame interior, a sleeve extending upwardly from the bottom wall, an electrical socket for receiving the electrical end of a lamp and received within the sleeve for axial movement between retracted and extended positions with respect to said bottom wall, means on the top wall providing a face of heat insulating and cushioning material for engaging the opposite end of the lamp, said face and sleeve being spaced apart a distance which permits the electrical end of the lamp to be moved into and out of the socket when the socket is retracted, a reflector on the inner side of the top wall, and means for positioning the socket in extended position so as to hold the opposite end of the lamp firmly against said face when its electrical end is received in the socket.
