BRACKET.

Application filed .Tune 20, 1924, Serial No. 721,313. Renewed August 13, 1925.

To aZZ whom it may concer/n.:

B e it known that I, HENRY M. KOFSKY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Brackets, of which the following is a specification.

The object of this invention is to provide an improved bracket, particularly designed and adapted for use in securely attaching lighting fixtures to a wall.

I aim to adapt the bracket for attachment by the usual screws to a standard outlet box through which the ends of electric conductors are made available for connection to the wires and lamps of a fixture.

I also aim to adapt such -a-bracket for supporting wall fixtures by a plurality of di'erent means, according to their own provisions for support: i. c., some fixtures have a recessed plate with a bar to be directly supported by the bracket; while other tixtures have a plate (either recessed or solid) without a bar, but generally provided with an aperture for a securing member to hold the fixture to the bracket. In this latter cas-e, a threaded nipple or bolt as securing member generally has one end engaged in a threaded aperture in the bracket. and an ornamental nut threaded on its other end. In either case, the assembled parts securely yet removably attach the fixture to the outlet box, and thus to the wall.

`With the foregoing and other objects in view, the present invention comprises additional novel details of construction and operation hereinafter fully brought out in the following description, when read in conjunction with the accompanying drawings, in which Fig. 1 is a. vertical transverse sectional view of an outlet box and an electric lightpiixture secured thereto bvmcans of a nipple.; Fig. 2 is a similar section showing` the fixture secured by 'means of a bar entirely hidden from the front of the plate;

Fig. 3 is a horizontal sectional view of the plate of Fig. 2 per se; and Fig. 4 is a perspective view of the improved bracket per se.

Referring toi the drawings, an electric lighting fixture is illustrated as comprising a concave back-plate 1 having an ornamental marginal corrugation 2 terminating in a peripheral flange 3, which in practice abuts directly against the wall 4 to which' the fixture is secured. Substantially centrally of said plate is an aperture 5 through which projects outwardly a threaded nipple 5, ca rrymg upon its outer free end an ornamental or other desired form of n ut 6. A second aperture 7 in said plate permits electric conductors (not shown) to extend from the rear of the plate toward and through the fixture arm 8, also secured to said plate, and carrying upon its outer end (for example) a. suitable socket 9, a candle extension 10, and an electric light bulb 11.

As usual, the wall 4 has a recess with a standard outlet box therein. This outlet box comprises a. top wall 12 and a bottom wall 13, connected by a rear wall 14 and opposite side walls 15 (the nearer of which latter is not shown). rl`he upper and lower walls arekk provided with suitable means 16 for securing the, box to any convenient adjacent portion of the wall recess, and also with upwardly and downwardly extending projections 17 and 18, each havingathreaded aperture to receive a screw 19.

Referring to Fig. 4, the preferred embodiment of the invent-ion here shown comprises a body portion 20 provided at one end with a laterally elongated aperture 21, and at its other end (preferably) reduced extension as at 22 to afford more room beside it for electric conductors and provided with a laterally elongated aperture 23,-the purpose of said apertures being, as shown in Figs. 1 and 2, to receive the outer portions of the screws 19 above referred to.

The body portion of the bracket is provided, substantially midway between the apertures 21 and 23, with a threaded aperture 24, surrounded by a substantially cylindrical flange formed by first creating a smaller hole than desired and then drawing the metal surrounding said hole outwardly. Such ianging of the aperture 24 affords a longer threaded surface and thus assures greater contact and more rigid relations between the bracket and box and the nipple 5.

The bracket is 'also provided with an L- shaped, upwardly extending hook 25, spaced and, as shown in Fig. 4, punched from the body portion between the apertures 21 and 24. This hook portion 25 is so located as to be in line with and receive therethrough, in a transverse direction, a bar 26 which extends between and is attached to laterally opposite regions of the inner (normally hidden) surfaces of the corrugations 2 and iiange 3.

Vhen a fixture of the type shown'from and secured to Fig. 1 is being installed, it is supported in the outlet box by means of the nipple-5 secured in the vaperture 2 4 of the improved bracket-the nut 6, and without regard to the hooked portion 25 of the bracket. On the other hand, when the fixture embodies a plate having no provision for the use of the nipple 5, but instead provided With the bar 26, said bar is caught over the hooked portion 25 of the bracket and the fixture secured in position. as shown in Fig. 2.- Thus, there is provided what might well be termed a universal bracket, of efficient operations, and obviously characterized by low cost of production.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is 1. A bracket of the character described having a body portion with apertures adjacent its ends, a hook spaced fromthe body portion of said bracket between sald apertures, and also a threaded aperture between said first-named apertures; saidhook being adapted either with or independently of said last named aperture to receive and support a part of a fixture',

2. A bracket yhaving a body portion provided adjacent to its ends with aperturesha threaded aperture positioned between sald first-named apertures, and a hooked portion struck out from the body portion of said bracket and adapted either with or independently of said last-named aperture to receive and support a part of a fixture.

3. A bracket of the character described having a body portion with apertures adjaand saidlast-named aperture, and adapted either with or independently' of said' lastvnamed aperture to receive and support a part of a fixture.

4. A bracket for securing a wall fixture to an outlet box having a body portion reduced to afford room beside it for electric conductors and provided with apertures adjacent its ends adapted to receive supporting screws.

third aperture positioned between said first apertures, the metal surrounding said third aperture being drawn axially to form a cylindrical cross-section and internally threaded to receive a correspondingly threaded nipple or bolt for attaching a fixture to said bracket.

6. A bracket having a body portion provided adjacent to its ends with laterally elongated apertures adapted to receive supporting screws carried by an outlet box, a third aperture positioned between said first apertures, the metal surrounding said third aperture being drawn axially to 'form a cylindrical cross-section and internally threaded to receive a correspondingly threaded nipple or bolt for attaching a fixture to said bracket, and a hook spaced from Said body portion and adapted to support thereon the weight of a fixture, either with or independently of said threaded aperture.

In testimony whereof I have aiixed my signature.

HENRY M. KOFSKY.
