C NEWMAN ET AL ADJUSTABLE BRACKET SUPPORT Filed Nov. 14, 1928 17 LC "67 Z156: Charles \Nswman Enesi (I k/lppleion Patented Jan. 5, 1932 UNITED STATES PATENT OFFICE CHARLES 'NEWMAIN, OF NEW YORK, N. Y., AND ERNST G. APPLETON, OF CHICAGO,

ILLINOIS, ASSIGNORS TO ROAOH-APPLETON MANUFACTURING CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS Y COMPANY, OF

ADJUSTABLE BRACKET SUPPORT Application filed November 14, 1928. Serial 170.31%),220.

The present invention relates to adjustable.

bracket supports.

More particularly the present invention relates to a combination of an outlet receptacle and supporting means for an electric bracket, which supporting means permits adjustment of said bracket after the electric outlet receptacle has been secured in position.

An object of the present invention is to provide construction of the kind referred to which is cheap to manufacture, sturdy, and

well adapted to meet commercial needs. A'further object is to provide an adjustable bracket support which is simple for an artisan to handle.

Further objects will appear as the description proceeds.

Referring to the drawings- Figure 1 is a view in perspective of an no outlet receptacle having cooperatively associated therewith an ad ustable bracket support embodying theprinciples of the present invention; and

Figure 2 is a horizontal sectional view taken along the plane indicated by the arrows 2-2 of Figure 1. An electric outlet receptacle is indicate by the numeral 10, which receptacle may take any preferred form. Said rece tacle 10 may be secured in place by means 0 nails 11-11,

which may be driven into any convenient supporting means 12; or, said receptacle may be secured in place in any other preferred manner, as for example by box su porting ears such asillustrated in United tates Patent No. 1,597,243, granted to the present; applicants on August 24, 1926. Said receptacle 10 is provided with the usual knock-outs 13-13, which knock-outs, when removed, permit 'entry of electric house wires. The open face of the receptacle 10 is provided with the readily removable cover plate 14 having the opening 15'. In the particular cover plate 14 illustrated, said opening 15 is disposed within an outwardly swedged portion 16 presenting the substantially parallel side edge ortions 17-17. The cover plate 14 ordinaril has its front face at the boundaries of sai face approximately flush with the plane defining the outer wall of the the bracket 19 having the cup-shaped portion plaster, which plane is indicated in Figure 2 by the numeral 18.

Disposed in covering relationship withtheoutlet receptacle 10 and 'cover plate 14 is 66 20, the edge of which is adapted to rest against the plaster. As brackets are ordinarily provided, they have electric wires adapted to be spliced. to the electric house wires entering the outlet receptacle 10, sufiic ient slack being provided to permit such splicing.

According to the present invention, the bracket 19 is secured to the cover plate 14 of the outlet receptacle 10 by means'of an ad justable bracket support, indicated as a whole by the numeral 21. Said bracket support'21 comprises a pair of complementar clamping plates 22 and 23, respectively. Said plates 22 and 23 may be of substantially the same width and are of sufiicient length to embrace the two parallel side edges 17-17. As illustrated in Figure 2, the extremities of the plate 23 are swedged outwardly a small amount, whereby when said plates 22 and 23 are in 76 gripping relationship with the edges 17-17, said plates may be relatively close together.

Each plate 22 is provided with a pair of screw-threaded apertures 24-24 for the reception of screws 25-25, which screws have their heads 26-26 disposed in abutting relationship with the outer face of the plate 23. The plate 22 is provided with a central aperture 27 of suflicient diameter to loosely receive an annular boss 28 swedged rearwardl from the central portion of the plate 23, w ereby said plate 22 is. s'wingingly carried by the plate 23. The screws 26-26 hold the plates 22 and 23 against swinging movement after said plates22 and 23 have been mounted upon the coverplate 14. Said boss 28 is interiorly screw-threaded for the reception of a' screw 29, which may be provided with an ornamental capnut 30. It will be understood without detailed explanation that the clamping member 21 comprising the plates 22 and 23 may be adjusted relative to the cover plate 14, whereby even after the outlet receptac e 10 has been secured in position, the bracket 19 may be adjusted throughout a distance equal to the range of movement of the lates 22 and 23 within the opening 15 in sai cover plate 14. Adjustment is had by the simple expedient of loosening one or both of the screws -25 and moving the plates 22 and 23 to the desired position, after which the screws 25-25 may be tightened. The bracket 19 may then be secured in place by applying the cap nut to the screw 29.
