OUTLET BOX SUPPORT Filed Sept. 2l, 1926 `INVENTOR Patented July 11, 1933 WILLIAM L. LADEMANN, OF NEW YORK, N. Y.

OUTLET BOX SUPPORT Application led September 21, 1926. Serial No. 136,768.

The objects of this invention are to pro-- vide means for supporting outlet boxes, switch boxes and the like from the steel bucks which have come into such general use for door frames, window frames, etc., andto furnish such means ina simple, inexpensive and` thoroughly practical form, readily attachable to the buck andadapted to ,provide Y a firm, rigid support for holding the switch box or other device inthe desired position. The invention embodies a number of novel features of construction, combinations and relations of parts, as will be clear from the following specification, including the drawing accompanying and forming part of the same.

Figure 1 is a plan View of a supporting bracket embodying the invention, shown ap- 2 plied to the vertical leg of a steel buck and having a portion of the supporting arm and the box applied thereto shown in section.

Figure 2 is a front elevation of the device, the nearv side of the buck being removed for the sake of clearness.

The form of the invention herein disclosed comprises a back member 3 in theshape of a bar adapted to span the open side of the steel buck indicated at 4 and a supporting '3b arm projecting from said back member.

The supporting arm is shown as an angularly bent strip having one leg 6 `overlying the face of the back strip and secured thereto by rivets 7, 8, the other leg forming the sup- The end 9 of the portion 6 '55 porting arm o. l extends beyond the securing rivet 8 and is shown as flared outwardly to form with the back piece, a wedge-like opening to receive the edge 10 of the buck. The rivet 8 at the tip of this opening forms a stop for engagement with the edge of the buck to positively position the back strip laterally with respect to the buck.

At the opposite end the back member is secured to the opposite edge l1'of the buck by a clamp plate 12 overlying and adjustably n secured to the back piece by screw 13. This clamp plate is indicated as slotted at 14 to allow for various adjustments of the clamp plate andV to permit said plate Vbeing slid backclear of the edge of the buck as indicated at 12a.

The outlet box, switch box or the like indicated at 15 may be secured to the supporting arm in variousways. It is shown in the illustration as having two sets of spaced hoes 16 therein to receive, in various relations, securing screws 17 passed through the bottom of the box. :This method -of fastening enables the box being supported at different distances D away from thebuck and the adjustable clamp structure enables the box being supported at different heights in respect to the buck.

`In order that the box may be supported in different positions laterally of th-e buck, the supporting arm 5 is shown as positioned ,offcenter in respect to the clamp structure so that when the box is applied to one face of the supporting arm, as indicated in the full lines, it will be properly positioned-for one wall surface 18 and when supported on the back of the arm, as indicated in broken lines, it will be positioned for a dierent wall sur'- faceV 19, the latter being for instance a tile r wall and the former being for example, an d ordinaryplaster surface.

The bracket is easily applied by entering the back lpiece through the open side of the' buck and turning it horizontally so as t0 bringthe fixed clamp at one end of thev base piece over one edge of the buck, after which the clamp piece 12 is shifted to overlap the front of the opposite edge of the buck piece' and the screw then tightened to ymake said U, clamp secure. The tightening of this clamp 3u also has a. wedging effect, since the clamp stands at an angle to the back piece and opcrates as it is tightened to force the clamp at the opposite fend the more firmly into engagement with the buck. Y An interlock with the 9G buck is thereby secured which fastens the bracket rigidly and firmly in place, holding it immovable even under the rough treatmentwhich such devices are liable to receive.
