Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
In a lamp socket for acceptance in a complementary aperture in the wall of a lamp housing, the improvement comprising a cylindrical sleeve having a radially outwardly extending flange at one end thereof, a spring washer secured in juxtaposed relation to the flange of said sleeve, said spring washer having a plurality of circumferentially spaced, axially extending guide fingers for engaging the edge face of the aperture in the lamp housing, and a plurality of circumferentially spaced axially extending locking fingers on said spring washer between said guide fingers, said locking fingers having cantilevered flanges, respectively, extending radially outwardly in spaced parallel relation to the flange on said sleeve so as to be engageable with the wall of the lamp housing on the opposite side thereof from the flange on said sleeve, one radially extending edge portion of the flanges on said locking fingers having an axially and circumferentially extending slope so as to form a ramp for camming engagement with the wall of the lamp housing thereby to apply an axial bias to said sleeve upon rotation of said socket relative to the lamp housing.

Claim 4
Dependent Claim
23 words
A socket as recited in claim 2, wherein the detent on said cantilevered flange is disposed on a cantilevered circumferentially extending portion thereof.
