Abstract
Abstract A lamp socket provided with resilient pawls spaced about its periphery, and a resilient member acting against the central stud. The pawls retract with the passage of a lamp into the socket and once the lamp is inserted, the pawls and resilient member apply pressure against the sides and bottom of the base to hold the lamp in place. Electrical contact is established through the pawls on the periphery of the lamp base and by the resilient member acting on the central stud.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
247 words
A socket assembly for a lamp having a cylindrical base provided with a first electrical contact at the end thereof and with a second electrical contact in the form of a continuous radially extending annular flange, said socket assembly comprising a metallic cylindrical sleeve having an inner diameter larger than the outer diameter of said base so that said base is spaced from said cylindrical sleeve, said cylindrical sleeve being open at one end for axial insertion of the base of said lamp, three tongues cut from said cylindrical sleeve and bent to extend resiliently from a point adjacent said one end inwardly at an angle to the axis thereof, said tongues being spaced uniformly from each other and having free ends facing oppositely to the direction of insertion of the base of said lamp, said tongues being distendable outwardly on insertion of the base of said lamp into said cylindrical sleeve to permit said flange to pass the free ends of said tongues and spring means mounted at the other end of said cylindrical sleeve for making electrical connection with said first electrical contact comprising a sleeve acting on said first electrical contact in a direction opposite to the direction of insertion of the base to uniformly bias said base and cause the flange to electrically engage with the free ends of said tongues and to cause said lamp to center and firmly seat in said socket assembly with said base spaced from said cylindrical sleeve.
Claim 2
Dependent Claim
247 words
A socket assembly for a lamp having a cylindrical base provided with a first electrical contact at the end thereof and with a second electrical contact in the form of a continuous radially extending annular flange, said socket assembly comprising a metallic cylindrical sleeve having an inner diameter larger than the outer diameter of said base so that said base is spaced from said cylindrical sleeve, said cylindrical sleeve being open at one end for axial insertion of the base of said lamp, three tongues cut from said cylindrical sleeve and bent to extend resiliently from a point adjacent said one end inwardly at an angle to the axis thereof, said tongues being spaced uniformly from each other and having free ends facing oppositely to the direction of insertion of the base of said lamp, said tongues being distendable outwardly on insertion of the base of said lamp into said cylindrical sleeve to permit said flange to pass the free ends of said tongues and spring means mounted at the other end of said cylindrical sleeve for making electrical connection with said first electrical contact comprising a sleeve acting on said first electrical contact in a direction opposite to the direction of insertion of the base to uniformly bias said base and cause the flange to electrically engage with the free ends of said tongues and to cause said lamp to center and firmly seat in said socket assembly with said base spaced from said cylindrical sleeve.
Claim 3
Dependent Claim
49 words
The socket assembly according to claim 1, including an insulator closure member fixed at the other end of said cylindrical sleeve, and wherein said spring means comprises a compression spring seated at one end against said closure member and at the other end against the base of said lamp.
Claim 4
Dependent Claim
19 words
The socket assembly according claim 1 including contact means integrally formed with said cylindrical sleeve and spring means respectively.
Claim 5
Dependent Claim
28 words
The socket according to claim 2, including contact means comprising prongs extending axially from the closure member in electrical connection with said cylindrical sleeve and said spring means.
Claim 6
Dependent Claim
30 words
The socket assembly according to claim 2 including an auxilliary spring means concentrically disposed about said compression spring being urged between the closure member and the base of the lamp.
Claim 7
Dependent Claim
65 words
The socket assembly according to claim 1, including means for removing said lamp from said socket assembly comprising a body having a plurality of fingers extending outwardly therefrom in a generally cylindrical arrangement adapted to fit over said lamp between said cylindrical sleeve and base into engagement with said tongues, said fingers being resiliently biased radially inward to grasp said lamp and permit extraction thereof.
