Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
In a clip on the end of a conductor for forming a terminal for a lamp bulb socket, a member having on the rear end attachment means for securement to an electric conductor and on the opposite end a head end divided into a plurality of spring sections which are movable toward each other, and which are flanged inwardly to form a substantially closed end at least one of the sections having a rigid locking element thereon for preventing the reverse movement of the member after said head end has been moved beyond the end of an aperture in a socket element, said head end forming a terminal the projecting end of which is directly engaged by a contact on a light bulb when supported within a socket.
Claim 2
Dependent Claim
128 words
In a clip on the end of a conductor for forming a terminal for a lamp bulb socket, a member having on the rear end attachment means for securement to an electric conductor and on the opposite end a head end divided into a plurality of spring sections which are movable toward each other, and which are flanged inwardly to form a substantially closed end at least one of the sections having a rigid locking element thereon for preventing the reverse movement of the member after said head end has been moved beyond the end of an aperture in a socket element, said head end forming a terminal the projecting end of which is directly engaged by a contact on a light bulb when supported within a socket.
Claim 3
Dependent Claim
44 words
In a clip as recited in claim 1, wherein said aperture is provided in a spring pressed sleeve in a socket, said sleeve having flanged ends which permit axial movement of the sleeve and clip when engaged by a contact of a light bulb.
