Abstract
Abstract A sheet metal bracket having a pair of triangular shaped plates supports an outlet box, switch box and the like on ceiling or floor joists or sidewall studding. The flexibility of the sheet metal of the cantilever supported bracket permits the plate member to assume various angular positions with respect to its mounting on the joists or studding. A plurality of longitudinally spaced apertures on the bracket permit various mounting locations and the optional use of non-metallic and conduit type wiring. A modified support uses two telescoping interlocking engaging brackets to provide a rigid support between two laterally spaced joists or studding.

Claim 1
Independent Claim
236 words
A bracket device for mounting an outlet box having openings therein adapted for the insertion of electrical conduit type wires, said bracket device being supported between a pair of laterally spaced building members such as wooden joist or stud means, said device being formed of rElatively thin sheet metal and comprising a first housing including a pair of triangular shaped apertured plate members, each plate member having a short leg portion and a long leg portion; an elongated apertured member structurally connected to the long leg portions of each plate member; said plate members being integrally provided with flange members projecting outwardly from the short leg portions, said flange members being capable of being secured to one of said joist or stud means; the edge connections among the plate members and the elongated member forming hinge means; the above-defined housing being duplicated as a second housing; said first and second housings being supported in a canti-lever manner to the laterally spaced building members opposite each other whereby the outermost ends of the respective plate members are arranged in a telescoping interlocking engaging manner to provide a single longitudinally extensible and adjustable support and said apertures of the plate and elongated members being capable of receiving screw means for the rigid securing of the outlet box to said bracket device whereby the electrical conduit type wires may be readily insertable in the openings of the outlet box.

A bracket device for mounting an outlet box having openings therein adapted for the insertion of electrical conduit type wires, said bracket device being supported between a pair of laterally spaced building members such as wooden joist or stud means, said device being formed of rElatively thin sheet metal and comprising a first housing including a pair of triangular shaped apertured plate members, each plate member having a short leg portion and a long leg portion; an elongated apertured member structurally connected to the long leg portions of each plate member; said plate members being integrally provided with flange members projecting outwardly from the short leg portions, said flange members being capable of being secured to one of said joist or stud means; the edge connections among the plate members and the elongated member forming hinge means; the above-defined housing being duplicated as a second housing; said first and second housings being supported in a canti-lever manner to the laterally spaced building members opposite each other whereby the outermost ends of the respective plate members are arranged in a telescoping interlocking engaging manner to provide a single longitudinally extensible and adjustable support and said apertures of the plate and elongated members being capable of receiving screw means for the rigid securing of the outlet box to said bracket device whereby the electrical conduit type wires may be readily insertable in the openings of the outlet box.
Claim 3
Dependent Claim
216 words
A bracket device for mounting an outlet box having openings therein adapted for the insertion of electrical conduit type wires, said bracket device being supported on a building member such as wooden joist or stud means, said bracket device being formed of relatively thin sheet metal and comprising: a pair of triangular shaped aperture plate members, each plate member having a short leg portion and a long leg portion; an elongated apertured member structurally connected to the long leg portions of each plate member; said plate members being integrally provided with flange members projecting outwardly from the short leg portions; the edge connections among the plate members and the elongated member forming hinge means whereby said hinge means permit said plate members of assuming various angular positions relative to each other; and said flange members being capable of being secured at selective locations on said joist or stud means and said apertures of the plate and elongated members being constructed at spaced intervals adjacent to said hinge means along the entire length thereof, said apertures of the plate and elongated members being capable of receiving screw means for the rigid securing of the outlet box to said bracket device, whereby the electrical conduit type wires may be readily insertable in the openings of the outlet box.
