Abstract
Abstract In an adjustable fluorescent lamp holder for use in a lighting fixture, a plate member(s) pivotally mounts to an end panel of the fixture and said plate removably supports a lamp socket for accommodating this type of a lamp, and particularly a fluorescent lamp of the U-shaped variety. The plate is pivotal in its mounting to the panel, and a locking means is provided for fixing said plate to the same as when it has been adjusted for positioning of its attaching socket at an approximate location for mounting of a U-lamp of a particular size, in said plate, upon loosening of said locking means, capable of being pivoted for repositioning of said socket to dispose it for accommodating a U-lamp of differing size.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
104 words
In an adjustable fluorescent lamp holder for use in a lighting fixture incorporating at least one end panel, a plate member being pivotally mounted to said panel, a fluorescent lamp socket having socket wires connected thereto, said plate member having an opening therein to accommodate attachment of said socket and insertion of its wires therethrough, locking means disposed for fixing said plate member to said panel with its attached socket being disposed laterally with respect to the center of said plate. whereby upon loosening said locking means and pivoting the plate member its socket is repositioned for supporting a fluorescent lamp of differing size.
Claim 2
Dependent Claim
104 words
In an adjustable fluorescent lamp holder for use in a lighting fixture incorporating at least one end panel, a plate member being pivotally mounted to said panel, a fluorescent lamp socket having socket wires connected thereto, said plate member having an opening therein to accommodate attachment of said socket and insertion of its wires therethrough, locking means disposed for fixing said plate member to said panel with its attached socket being disposed laterally with respect to the center of said plate. whereby upon loosening said locking means and pivoting the plate member its socket is repositioned for supporting a fluorescent lamp of differing size.
Claim 3
Dependent Claim
46 words
The invention of claim 1 wherein said plate member is pivoted approximately 180* to dispose its socket to one side for support of a fluorescent lamp, and said locking means capable of being tightened to fix said plate stably to said panel to support said lamp.
Claim 4
Dependent Claim
100 words
In an adjustable fluorescent lamp holder for use in a lighting fixture incorporating at least one end panel, said fixture being of the type designed to accommodate U-shaped lamps of differing size, a plate member pivotally mounted to said panel, a fluorescent lamp socket connected to said plate, locking means disposed for fixing said plate member to said panel, said plate member disposing its connected socket laterally for accommodating a lamp of one size, and said plate member upon loosening of said locking means and being pivoted approximately 180* disposing its connected socket for accommodating a lamp of differing size.
Claim 5
Dependent Claim
100 words
In an adjustable fluorescent lamp holder for use in a lighting fixture incorporating at least one end panel, said fixture being of the type designed to accommodate U-shaped lamps of differing size, a plate member pivotally mounted to said panel, a fluorescent lamp socket connected to said plate, locking means disposed for fixing said plate member to said panel, said plate member disposing its connected socket laterally for accommodating a lamp of one size, and said plate member upon loosening of said locking means and being pivoted approximately 180* disposing its connected socket for accommodating a lamp of differing size.
Claim 6
Dependent Claim
109 words
In a lighting fixture for accommodating U-shaped lamps of more than one size, said fixture incorporating at least one end panel, a pair of fluorescent lamp holders, each holder including a plate member being pivotally mounted to said panel, a fluorescent lamp socket connected to each plate, locking means disposed for fixing each plate member to said panel, each plate member disposing its connected socket laterally and distant from each other to accommodate a lamp of large size, and each plate member upon loosening of said locking means and upon their pivoting approximately 180* disposing their connected sockets in a closer relationship to accommodate a lamp of smaller size.
Claim 7
Dependent Claim
109 words
In a lighting fixture for accommodating U-shaped lamps of more than one size, said fixture incorporating at least one end panel, a pair of fluorescent lamp holders, each holder including a plate member being pivotally mounted to said panel, a fluorescent lamp socket connected to each plate, locking means disposed for fixing each plate member to said panel, each plate member disposing its connected socket laterally and distant from each other to accommodate a lamp of large size, and each plate member upon loosening of said locking means and upon their pivoting approximately 180* disposing their connected sockets in a closer relationship to accommodate a lamp of smaller size.
Claim 8
Dependent Claim
67 words
The invention of claim 1 wherein said socket attaches loosely to a connecting mount providing for slight lateral adjustment of said socket with respect to its pivotal plate member, said mount incorporating a pair of projections which are disposed for engaging the edges of said plate opening thereby fixing said mount with respect to said pivotal plate member, and said mount being disconnectable from said plate member.
Claim 9
Dependent Claim
42 words
The invention of claim 5 wherein said pivotal plate is removable from said end panel and capable of attachment on its reverse side to said panel, said mount and connecting socket being disconnectable from said plate for reattachment to its reverse surface.
