Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
In combination: an electrically wired socket including electrical connection means in the socket, a lightbulb with an associated filament, a base, and electrical leads coupled to said filament and extending out of said base, said base being sized and configured for snug receipt in said socket with said electrical leads in electrical engagement with said electrical connection means, said base having an axial face adjacent said bulb of a greater diameter than said bulb, keeper means having a hollow cylindrical form including a lateral portion with an opening through which the bulb extends, said lateral portion having an inner annulus, said inner annulus bearing axially against said axial face of said base outboard of said bulb and, latch means having first and second interengaging portions respectively integrally fixed on said socket and said cylindrical form for normal hooked-up engagement with one another to releasably maintain said lightbulb in said socket at all times in normal use.
Claim 2
Dependent Claim

In combination: an electrically wired socket including electrical connection means in the socket, a lightbulb with an associated filament, a base, and electrical leads coupled to said filament and extending out of said base, said base being sized and configured for snug receipt in said socket with said electrical leads in electrical engagement with said electrical connection means, said base having an axial face adjacent said bulb of a greater diameter than said bulb, keeper means having a hollow cylindrical form including a lateral portion with an opening through which the bulb extends, said lateral portion having an inner annulus, said inner annulus bearing axially against said axial face of said base outboard of said bulb and, latch means having first and second interengaging portions respectively integrally fixed on said socket and said cylindrical form for normal hooked-up engagement with one another to releasably maintain said lightbulb in said socket at all times in normal use.
Claim 3
Dependent Claim
49 words
The device as set forth in claim 1 wherein said keeper means includes a skirt depending from said lateral portion and said latch means includes a pair of legs extending from said skirt axially having barbed ends and said barbed ends normally in hooked-up engagement with said socket exterior.
Claim 4
Dependent Claim
27 words
The device as set forth in claim 1 wherein said electrical leads extending through said lamp base are turned back upon the exterior of said lamp base.
Claim 5
Dependent Claim
45 words
The device as set forth in claim 1 wherein said axial face of said base is provided with a bevel and said keeper means includes on said inner annulus a companionately sized and configured beveled portion for interengagement with said beveled portion of said base.
Claim 6
Dependent Claim
28 words
The device as claimed in claim 1 wherein the top of said cylindrical form is said lateral portion and said bulb extends through said opening of said top.
Claim 7
Dependent Claim
30 words
The device as claimed in claim 5 wherein said opening is larger than the exterior diameter of said bulb thereby permitting air flow between said keeper means and said bulb.
Claim 8
Dependent Claim
29 words
The device as claimed in claim 6 wherein said opening has a central circular region through which protrudes said bulb and two slots radially extensive from said central region.
Claim 9
Dependent Claim
42 words
The device as claimed in claim 1 wherein said keeper means includes a skirt depending from said lateral portion and said latch means includes a tongue and groove fit respectively between the inside of said skirt and the outside of said socket.
Claim 10
Dependent Claim
46 words
The device as claimed in claim 1 wherein said keeper means includes a skirt depending from said lateral portion and said latch means includes a pair of tabs radially protruding inward from said skirt which cooperates with a ledge formed in the exterior of said socket.
Claim 11
Dependent Claim
16 words
The device as claimed in claim 9 wherein said tabs are oppositely disposed on said skirt.
Claim 12
Dependent Claim
71 words
The device as claimed in claim 10 wherein the socket has a pair of flat side surfaces and the interior surface of said skirt except for said tabs is in substantial contact with the exterior of said socket above said ledge except for said side surfaces such that said keeper means is adapted to be axially movable with respect to said socket when said tabs and side surfaces are radially aligned.
