Claim 1
Independent Claim
344 words
An electric lighting fixture comprising: a base section having an attaching portion and an integral arm projecting outwardly therefrom; said arm being hollow and having a top wall, a closed outer end wall, side walls, and a short bottom wall connecting the portions of said side walls adjacent to the attaching portion of said base section; said outer end wall, short bottom wall, and side walls providing said arm with a downwardly facing opening; said outer end wall having a first latching means comprising a protrusion integral therewith and extending into said opening; a pair of projections spaced apart on said short bottom wall of said arm; and a lamp carrying section closing the opening in said arm, the lamp carrying section comprising a top wall and depending peripheral wall of a size to receive the neck of a globe; the top wall of said lamp carrying section abutting the lower edges of said side walls, the bottom edge of said end wall, and the outer edge of said short bottom wall of said arm; said lamp carrying section including a lamp socket housing disposed in the top wall of said lamp carrying section; a pair of slots in said depending peripheral wall spaced apart to receive said pair of projections, said pair of projections and said pair of slots coacting to provide support for the lamp carrying section adjacent to the short bottom wall of said arm; said slots having a region of a first width to receive said projections and a region of a second narrow width whereby there is provided between said pair of slots a resilient section in said depending peripheral wall; and a second latching means comprising a protrusion integral with said lamp carrying section; whereby said resilient section of said depending peripheral wall bears flexibly against the front edge of said short bottom wall, urging said second latching means toward said first latching means, said first and second latching means coacting to provide support for the lamp carrying section adjacent to the outer end wall of said arm.
Claim 2
Dependent Claim
344 words
An electric lighting fixture comprising: a base section having an attaching portion and an integral arm projecting outwardly therefrom; said arm being hollow and having a top wall, a closed outer end wall, side walls, and a short bottom wall connecting the portions of said side walls adjacent to the attaching portion of said base section; said outer end wall, short bottom wall, and side walls providing said arm with a downwardly facing opening; said outer end wall having a first latching means comprising a protrusion integral therewith and extending into said opening; a pair of projections spaced apart on said short bottom wall of said arm; and a lamp carrying section closing the opening in said arm, the lamp carrying section comprising a top wall and depending peripheral wall of a size to receive the neck of a globe; the top wall of said lamp carrying section abutting the lower edges of said side walls, the bottom edge of said end wall, and the outer edge of said short bottom wall of said arm; said lamp carrying section including a lamp socket housing disposed in the top wall of said lamp carrying section; a pair of slots in said depending peripheral wall spaced apart to receive said pair of projections, said pair of projections and said pair of slots coacting to provide support for the lamp carrying section adjacent to the short bottom wall of said arm; said slots having a region of a first width to receive said projections and a region of a second narrow width whereby there is provided between said pair of slots a resilient section in said depending peripheral wall; and a second latching means comprising a protrusion integral with said lamp carrying section; whereby said resilient section of said depending peripheral wall bears flexibly against the front edge of said short bottom wall, urging said second latching means toward said first latching means, said first and second latching means coacting to provide support for the lamp carrying section adjacent to the outer end wall of said arm.
Claim 3
Dependent Claim
72 words
An electric lighting fixture according to claim 1 wherein said projection on the short bottom wall of said arm extends through said opening in the depending peripheral wall of said lamp carrying section, said projection extending beyond said depending peripheral wall and being of a length to engage and provide support adjacent to said short bottom wall for that portion of the neck of a globe disposed in said lamp carrying section.
Claim 4
Dependent Claim
60 words
An electric lighting fixture according to claim 1 including a single fastener element disposed in the depending peripheral wall of said lamp carrying section at a point substantially diametrically opposite said projection and engageable with the neck of a globe disposed in said lamp carrying section, said fastener element coacting with said projection to support the globe in said fixture.
