Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 166 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said mounting ends of said pair of spring means being curved and having projections frictionally engaging the housing side walls and socket guide portions defining said recesses.
Claim 2
Dependent Claim 166 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said mounting ends of said pair of spring means being curved and having projections frictionally engaging the housing side walls and socket guide portions defining said recesses.
Claim 3
Dependent Claim 167 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said socket members having lug means projecting therefrom, said socket-holding ends of said pair of spring means being curved and engaging said lug means of said socket members.
Claim 4
Dependent Claim 167 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said socket members having lug means projecting therefrom, said socket-holding ends of said pair of spring means being curved and engaging said lug means of said socket members.
Claim 5
Dependent Claim 217 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said pair of spring means comprising strip-shaped sheet metal springs, said socket members having a pair of lugs projecting from opposite sides thereof, the socket-holding end of each of said springs being bifurcated and comprising spaced branches connected by a transverse edge of said spring, said spaced branches having curved ends respectively gripping said pair of lugs of said socket member, said socket member being held between said curved branch ends and said transverse edge of said spring.
Claim 6
Dependent Claim 217 words
A floodlight comprising, in combination, a housing having a rear wall and side walls defining an interior chamber and a front opening opposite said rear wall, said rear wall having a pair of spaced socket guide portions at opposite side walls, said socket guide portions spaced from the side walls adjacent thereto defining recesses therebetween, a pair of elongated spring means each having a mounting end and a socket-holding end and being curved intermediate said ends, said pair of spring means seated at said mounting ends in said recesses for mounting the same in said housing, and a pair of socket members respectively held by said socket-holding ends of said pair of spring means in operative position adjacent said socket guide portions so that said socket members are resiliently movable in a path toward and away from each other, said pair of spring means comprising strip-shaped sheet metal springs, said socket members having a pair of lugs projecting from opposite sides thereof, the socket-holding end of each of said springs being bifurcated and comprising spaced branches connected by a transverse edge of said spring, said spaced branches having curved ends respectively gripping said pair of lugs of said socket member, said socket member being held between said curved branch ends and said transverse edge of said spring.
Claim 7
Dependent Claim 153 words
Electrical socket assembly for mounting in a lighting fixture or the like comprising, in combination, an electrically insulating socket member formed with a recess for receiving the end of a lamp or the like, said socket member having a pair of lug portions projecting from opposite sides thereof transverse the axis of said recess, a strip-shaped sheet metal spring having a curved mounting end and a socket-holding end and being curved intermediate its ends, said spring being adapted to be frictionally attached at its curved mounting end to the lighting fixture or the like, said socket-holding end of said spring being bifurcated and comprising spaced branches connected by a transverse edge of said spring, said spaced branches having curved ends respectively gripping said pair of lug portions of said socket member, said socket member being held in assembly with said spring between said curved branch ends and said transverse edge of said spring.
