OUTLET BOX Filed April 1. 1930 Patented Mar. 10, 1931 PATENT GFFIQE JAMES MANGIN, OF NEW BRUNSWICK, NEW JERSEY OUTLET BOX Application filed April 1,

The present invention relates to outlet; boxes and particularly refers to an improved form of outlet box whereby it may be positioned without preliminary measurement so that it will fall flush with the plaster or linished facing of a wall partition, said position being determined by the usual standard wall studs or two by fours used in wall constructions of dwellings. The outlet box of w my invention is particularly useful in wiring new dwellings and other buildings and is an improvement over the type of outlet box disclosed in my co-pending application, Se-

rial No. 384,300, filed August 8, 1929.

The principal object of the invention is to provide an improved form of outlet box having a new form of support whereby a multiplicity of parts is eliminated and whereby the box may be adjusted or positioned without preliminary measurement to fall flush with the plastering or finished facing of a wall partition and which may be placed, either in a vertical or horizontal position-as required.

Other objects and advantages of my invention will appear more fully hereinafter from the following detailed description taken together with the drawings, in which:

Fig. 1 is a perspective view of my improved outlet box showing its application to a wall and wall studding;

Fig. 2 is a perspective view of a modification showing the outlet box attached to flooring instead of the wall studding; and

Fig. 3 is another embodiment, also in perspective, in which a round outlet box is used.

Referring more particularly to the drawings, the outlet box 1 is composed of the usual end walls 2, side walls 3 and a rear wall 4, the front face 5 of the outlet box being open for the reception of receptacles, switches or other devices adapted to be carried by the outlet box. The end walls 2 are provided with the usual lugs 6 for the reception of strap elements and the like.

The novel feature of my invention is the provision of a projecting flange 7 extending from one of the side walls 3 which may bemade integral therewith, as indicated in the drawings, or may be separate and attached the flange is oifset to provide a clearance between the flooring and the lower wall of the 1930. Serial No. 440,758.

to one of the end walls 3 in any suitable manner. The flange is provided with longitudinal slots 8 for the reception of screws 9 so that the box may be attached to the wall studding 10. Additional lugs 11 having slots 12 for the reception of screws 13 are provided for attaching the outlet box to the studding 10. The length or depth of the flange 7, in accordance with my invention, is made such that the combined depth of the wall 3 and the flange 7 will be equal to the combined thickness of the finished facing or plaster 14 0f the wall and the studding 10. That is, the depth from the front face 5 0f the outlet box to the edge 15 of the flange 7 is equal to the dimension as, as indicated in Fig. 1. In order to properly locate the outlet box so that its front face shall fall flush with the finished facing 14, all that is required to do is to place the box so that the edge 15 of the flange 7 falls flush with the edge 16 of the stud 10. In this way, all preliminary measurement for properly locating the outlet box is eliminated.

In Fig. 2 is shown a perspective view of a modification in which the flange 7 is offset from the wall 3 by the portion 17 bent at right angles to the wall 3 and the flange 7 projecting at right angles to the offset portion 17 so that it extends parallel with the wall 3. The lugs 11 are also offset at 18 so that they shall lie in the same plane with the flange 7. This modification is particularly adapted for fuse toning the outlet box to the flooring 19 and outlet box. The length or depth of the flange 7, however, is the same as that in Fig. 1 so that the outlet box may be positioned in the same manner by making the edge 15 of the flange 7 align with the edge 16 of the wall stud 10.

In Fig. 3 is a further modification in pe spective, illustrating the application of my invention to a round type of outlet box indicated at 20, having the usual rear wall 21 and an open front 22. In this instance, the flange 23 is riveted or otherwise attached to the outlet box 21 and is arranged so that the combined depth from the front face 22 to the ml end 24 of the flange 23 is equal to thediinension a" indicated in Fig. 1. An auxiliary flange 25 is provided for fastening the outlet box to the stud and corresponds to the lugs 11 indicated in Figs. 1 and 2. V Slots 26 and 27 are provided in the flanges 23 and 25, respect-ively, for the reception of screws (not shown) whereby the outlet box may be attached to the wall studding.

. \Vhile I have shown several embodiments of my invention for purposes of illustration and description, other changes and modifications may be apparent therein to those skilled in the art and I, therefore, desire to be limited only by the scopeof the appended claims.

I claim: 1. An outlet box having a projecting flange, the combined depth of said box-and said flange being equal to'the combined thickprovided with :an integral projection form v ness of the wall studding and the finishing facing of a wall whereby sald box may be positioned to fallfiush with the finished facing or plaster of a wall and preliminary measurement for so positioning said outlet box thereby eliminated.

2.- An outlet box having one side thereof 7 provided with an integral projection forming a projecting flange, the combined depth of' said side and flange being equal to the combined thickness of the wall stud and the finished facing of a wall whereby preliminary measurement to position said outlet box so that its front-face shall fall flush with the finished facing or plaster of a wall is eliminated.

8. An outlet box having one'wall thereof longitudinal slots for the reception of fastening elements, said wall also being providedwith transverse extensions or lugs, the

combined depth of said'wall and said flange beingequal to the combined thickness of standard wall studding and the finished plasment. to position said outlet box so that its finished plaster of a wall whereby preliminary'measurement to position said outlet ter of a wall whereby preliminary measurefront face shall fallflush with the finished facing or plaster of a wall is eliminated.

4. An outlet box having one side thereof provided withan integral projection forming a projectingfiange, said flange being offset at the edge of the outlet box and extending parallel with said side, a'pair of lugs extending'from said side and offset to bein the same plane with said flange, the combined depth ofsaid side and flange from the front .face of the outlet box being equal to the combined thickness of standardwall studding and the box so that itsfront face shall fall flush with the finlshed facing 01'- plaster of a wall is eliminated.
