Abstract
Abstract A box bracket for stud wall construction is formed from a single sheet metal strap which has one major transverse right angle bend forming a vertical leg and a horizontal leg or arm with the vertical leg having a vertical offset overlapping the face of the stud while the horizontal arm extends in a horizontal plane over the top or bottom of the box and abuts the far wall panel. The horizontal and vertical legs are offset and the vertical leg is provided with a 45° gusset or panel which includes a keyhole opening and a slot, to each of which a different size box and plaster ring may be mounted. The vertical leg includes two spaced edge tabs or flanges between which a vertical edge of the box is grasped. The horizontal leg or arm includes an interior stiffening flange and an exterior U-shape knock-out opposite the flange. The knock-out would normally block one of the knock-outs in the box. If such knock-out is employed, then the fitting used for the electrical conduit will clamp the horizontal leg to the box improving rigidity. The horizontal arm also has a series of pairs of short transverse slots which enable the distal end of the leg to be field bent to form a downturned flange at three different locations corresponding to the depth of a stud.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
102 words
A box support for stud wall construction comprising a vertical leg having a front panel adapted to be secured to the face of the stud, and a horizontal leg extending rearwardly from the top of the front panel of the vertical leg, along the side of the stud, said horizontal leg being offset from the vertical leg and joined thereto by a gusset, means to secure an electrical outlet box and the like to the gusset, and means to field form flanges at different locations on the end of said horizontal leg whereby the box support will fit studs of different depths.
Claim 2
Dependent Claim
102 words
A box support for stud wall construction comprising a vertical leg having a front panel adapted to be secured to the face of the stud, and a horizontal leg extending rearwardly from the top of the front panel of the vertical leg, along the side of the stud, said horizontal leg being offset from the vertical leg and joined thereto by a gusset, means to secure an electrical outlet box and the like to the gusset, and means to field form flanges at different locations on the end of said horizontal leg whereby the box support will fit studs of different depths.
Claim 3
Dependent Claim
25 words
A box support as set forth in claim 1 including a vertically extending stiffening flange on one side of said horizontal leg toward the stud.
Claim 4
Dependent Claim
21 words
A box support as set forth in claim 2 including a U-shape knock-out in said horizontal leg opposite said stiffening flange.
Claim 5
Dependent Claim

Claim 9
Dependent Claim
36 words
A box support as set forth in claim 1 including a vertically extending offset in said vertical leg stiffening said vertical leg and providing an interior shoulder against which to fit a corner of the stud.
Claim 10
Dependent Claim
30 words
A box support as set forth in claim 8 including a sighting notch on the edge of said vertical leg adapted to register with an elevation mark on the stud.
Claim 11
Dependent Claim
128 words
A box support for a stud wall comprising a vertical leg and a horizontal leg, said vertical leg being primarily in the plane of the face of the stud, and said horizontal leg being primarily in the plane perpendicular to the side of the stud, a single right angle horizontal bend joining the vertical and horizontal legs, said vertical leg being offset from said horizontal leg whereby a front panel portion of said vertical leg will overlap and be positioned for attachment to the face of the stud when the horizontal leg extends rearwardly along the side of the stud, said horizontal leg including means to field bend the end thereof at different locations to fit the length of the horizontal leg to the depth of the stud.
Claim 12
Dependent Claim
128 words
A box support for a stud wall comprising a vertical leg and a horizontal leg, said vertical leg being primarily in the plane of the face of the stud, and said horizontal leg being primarily in the plane perpendicular to the side of the stud, a single right angle horizontal bend joining the vertical and horizontal legs, said vertical leg being offset from said horizontal leg whereby a front panel portion of said vertical leg will overlap and be positioned for attachment to the face of the stud when the horizontal leg extends rearwardly along the side of the stud, said horizontal leg including means to field bend the end thereof at different locations to fit the length of the horizontal leg to the depth of the stud.
Claim 13
Dependent Claim
