Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
277 words
A lamp socket for mounting in a ceiling having an aperture therefor and adapted to be used in electrical contact with the plurality of such sockets, comprising a tubular body member constructed on an electrically conductive material, the rearward end thereof being adapted to be positioned within said aperture in said ceiling and the forward end to hold the base of an electric light bulb therein, a flange member constructed of an electrically conductive material extending about said body member and in rigid contact therewith, said flange member defining a supporting surface adapted to abut said ceiling such that when an adhesive is positioned between said flange member and said ceiling said socket is supported from said ceiling, a portion of said flange member defining an electrical terminal, a spring contact member being carried by said body member, one end of said contact member being positioned within said tubular body member and terminating in a loop portion, said loop portion being adapted to abut a contact formed on the end of said light bulb base and making an electrical contact therewith, the other end of said contact member extending outwardly of said body member, near the rearward end thereof and forward along said body member to said flange member, said contact extending radially outward from said body member at said flange member and ending in a second electrical terminal, said second electrical terminal being adjacent and in substantially the same horizontal plane as said first terminal on said flange member, said contact member being electrically insulated from said body member and said flange member between said second terminal and said loop portion positioned within said body member.
Claim 2
Dependent Claim
277 words
A lamp socket for mounting in a ceiling having an aperture therefor and adapted to be used in electrical contact with the plurality of such sockets, comprising a tubular body member constructed on an electrically conductive material, the rearward end thereof being adapted to be positioned within said aperture in said ceiling and the forward end to hold the base of an electric light bulb therein, a flange member constructed of an electrically conductive material extending about said body member and in rigid contact therewith, said flange member defining a supporting surface adapted to abut said ceiling such that when an adhesive is positioned between said flange member and said ceiling said socket is supported from said ceiling, a portion of said flange member defining an electrical terminal, a spring contact member being carried by said body member, one end of said contact member being positioned within said tubular body member and terminating in a loop portion, said loop portion being adapted to abut a contact formed on the end of said light bulb base and making an electrical contact therewith, the other end of said contact member extending outwardly of said body member, near the rearward end thereof and forward along said body member to said flange member, said contact extending radially outward from said body member at said flange member and ending in a second electrical terminal, said second electrical terminal being adjacent and in substantially the same horizontal plane as said first terminal on said flange member, said contact member being electrically insulated from said body member and said flange member between said second terminal and said loop portion positioned within said body member.
Claim 3
Dependent Claim
49 words
The combination of claim 1 wherein said socket is adapted for mounting in a plaster ceiling having an acoustic covering, said flange member being positioned rearward of said forward end of said tubular body member a distance substantially equal to the thickness of said plaster and said acoustic finishing.
Claim 4
Dependent Claim
34 words
The combination of claim 1 wherein said socket is adapted for mounting in a ceiling having an acoustic covering, said flange member being positioned substantially adjacent the forward end of said tubular body portion.
Claim 5
Dependent Claim
53 words
The combination of claim 2 wherein said tubular body member has a pair of oppositely disposed longitudinal slots near the forward end thereof, each of said slots having a laterally disposed portion thereof, said slots being adapted to receive a pair of oppositely disposed studs mounted on the base of said light bulb.
Claim 6
Dependent Claim
43 words
The combination of claim 3 wherein said tubular body member has a pair of oppositely disposed longitudinal slots near the forward end thereof, said slots being adapted to receive a pair of oppositely disposed studs mounted on the base of said light bulb.
Claim 7
Dependent Claim
204 words
A lamp socket for mounting in a ceiling having radiant heating coils therein and an aperture for said socket extending through the ceiling, adjacent the ceiling joist and adapted to be used in electrical contact with the plurality of such sockets similarly mounted comprising a elongated tubular body member, the rearward end thereof being adapted to be positioned within said aperature in said ceiling and the forward end to hold the base of an electric light bulb therein, a spring contact member being carried by said body member, one end of said contact member being positioned within said tubular body member and terminating in a loop portion, said loop portion being adapted to abut a contact formed on the end of said light bulb base making an electrical contact therewith, the other end of said contact extending outwardly of said body member near the rearward end thereof and ending in an electrical terminal, a screw member extending into said tubular body portion and defining a second electrical contact, and a pointed flange extending radially outward from said tubular body portion near the rearward end thereof, said flange being adapted to be positioned within said ceiling joist, thereby supporting said lamp socket in said ceiling.
Claim 8
Dependent Claim
204 words
A lamp socket for mounting in a ceiling having radiant heating coils therein and an aperture for said socket extending through the ceiling, adjacent the ceiling joist and adapted to be used in electrical contact with the plurality of such sockets similarly mounted comprising a elongated tubular body member, the rearward end thereof being adapted to be positioned within said aperature in said ceiling and the forward end to hold the base of an electric light bulb therein, a spring contact member being carried by said body member, one end of said contact member being positioned within said tubular body member and terminating in a loop portion, said loop portion being adapted to abut a contact formed on the end of said light bulb base making an electrical contact therewith, the other end of said contact extending outwardly of said body member near the rearward end thereof and ending in an electrical terminal, a screw member extending into said tubular body portion and defining a second electrical contact, and a pointed flange extending radially outward from said tubular body portion near the rearward end thereof, said flange being adapted to be positioned within said ceiling joist, thereby supporting said lamp socket in said ceiling.
Claim 9
Dependent Claim
51 words
The combination of claim 6 wherein an aperture is provided in said tubular body portion said aperture extending through said body portion and perpendicular to the longitudinal axis thereof, whereby a nail can be driven through said aperture and into said ceiling joist thereby further supporting said socket in said ceiling.
Claim 10
Dependent Claim
104 words
The combination of claim 6 wherein said tubular body member has a pair of oppositely disposed longitudinal slots near the forward end thereof, each of said slots having a laterally disposed portion thereof, said slots being adapted to receive a pair of studs mounted on the opposite side of the base of said light bulb, whereby said light bulb is maintained within said tubular member by the urging of said loop portion of said contact member against said contact on the end of said light bulb base thereby forcing said stud members against the forward side of said laterally disposed portions of said slots.
