Abstract
Abstract A device for protecting a light emitting bulb such as an ordinary light bulb from impact and rain. The device includes a substantially cylindrical body which is closed at one end. A neck is formed through the closed end to accommodate a light socket and the body defines a cavity to enclose a light bulb positioned in the socket. Holes extend through the closed end of the body adjacent the cylindrical wall. The holes extend upwardly in tubes above the surface of the closed end. A circular flange extends inwardly from the closed end into the cavity. This flange is larger in diameter than the bulb to be placed within the cavity; and it extends to a knife edge. The outer extremity of each hole through the closed end is aligned with the inner surface of the substantially cylindrical wall while the inner extremity of each hole is aligned with the outer surface of the flange.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
119 words
A guard for a light emitting bulb, comprising a hollow body including a wall portion defining a cavity capable of surrounding a light emitting bulb, a top portion joined with said wall portion to close a first end of said cavity, a neck portion extending to said cavity through said top portion for receipt of a socket for a light emitting bulb, and holes extending through said body near said first end, wherein the improvement comprises a flange extending inwardly from said top portion and having a continuous, closed outer surface inwardly of said holes and disposed such that a projection of said outer surface defines a volume in said cavity capable of receiving a light emitting bulb therein.
Claim 2
Dependent Claim
119 words
A guard for a light emitting bulb, comprising a hollow body including a wall portion defining a cavity capable of surrounding a light emitting bulb, a top portion joined with said wall portion to close a first end of said cavity, a neck portion extending to said cavity through said top portion for receipt of a socket for a light emitting bulb, and holes extending through said body near said first end, wherein the improvement comprises a flange extending inwardly from said top portion and having a continuous, closed outer surface inwardly of said holes and disposed such that a projection of said outer surface defines a volume in said cavity capable of receiving a light emitting bulb therein.
Claim 3
Dependent Claim
35 words
The device of claim 1 wherein the improvement further comprises said holes extending through said top portion adjacent said wall portion and said top portion extending outwardly to form a tube about each said hole.
Claim 4
Dependent Claim
27 words
The device of claim 2 wherein the improvement further comprises the inner extremity of each of said holes being aligned with said outer surface of said flange.
Claim 5
Independent Claim
33 words
The device of any one of claims 2 and 3 wherein the improvement further comprises the outer extremity of each of said holes being aligned with the inner side of said wall portion.
Claim 6
Dependent Claim
17 words
The device of claim 1 wherein the improvement further comprises said flange extending to a knife edge.
Claim 7
Dependent Claim
46 words
The device of claim 4 wherein the improvement further comprises said holes with tubes being sufficiently spaced apart such that water which does strike the said top portion of the guard will flow in between the adjacent holes instead of over them and into the guard.
Claim 8
Dependent Claim
46 words
The device of claim 6 wherein the improvement further comprises said holes being of sufficient elongation so as to substantially eliminate the incidence of raindrops entering the guard directly via the said holes without first coming into contact with the side walls of the said holes.
Claim 9
Dependent Claim
46 words
The device of claim 7 wherein the improvement further comprises a substantially cylindrical inner flange which extends inwardly from said top portion of the guard and whose vertical downward projection at all points does not intercept the space defined and occupied by said light emitting bulb.
