PTTENT? 1 HENRY w. SMITH, on MENLO rARkmALIro NIA CORNER BRAQE Application filed January 9, 19129.

My invention relates to a brace suitable for use in a corner or at the uncture of several surfaces where it is desired that the surfaces geous features, some of which with the foregoing,will be set forth at length in the fol lowing descriptiomwhere I shall outline in full that form of myinvention which I have selected for illustration in the drawing accompanying and forming part of the present specification. In said drawing I have shown of corner brace embodying my invention, but it is to be understood that I do not limit myself to such type, as the invention, as set forth in the claims, may be e1n bodied in a plurality of forms.

Referring to said drawing: Figure 1 is a plan view of the device of my invention as it appears at one .step in its one type Figure 2 is a perspective view ofa corner with a brace of my invention disposed therein.

Figure 3 is a cross section thru an assembled device of my invention.

Figure 4: illustrates another form of the corner brace of my invention with certain additional features of construction.

While the device of my invention may be conveniently formed from various materials I preferably stamp it from a sheet of metal portions bled.

of the desired weight.

As shown in Figure 1, a plate 6 is stamped out in such a shape as to facilitate the fabrication of the device. Thus I preferably form the plate 6 with a trapezoidal outline and, situated at the opposite ends of the base 7 of the trapezoidally shaped plate, I also provide lips 8. and 9 which are preferably rectangular in outline.

I erably bend the lips "lines la and 16, away the device may Preferably I provide Serial No. 331,219.

a plurality of teeth 11 which are formed integrally with the plate 6 and extend therefrom at substantially a right angle toone face thereof. Portions of the lips- 8' and 9 are removed, preferably by stamping, to prov1 de the slots12 and 13.

' I likewise form, of sheet metal, a staple for use'in connection with mydevice. As illustrated inFigure' 1, the preferably trapezoidallyl shaped sheet 26' is provided with suitableangular extensions '27. 'These portions 27 are bent back upon the sheet at substantially right angles to form a staplev with suflicient distance between the extensions as to permit the ready insertion into the slotted 12 and'13 of the body when assem- The assembledfdevic'e is shown in'Figure 2 placed in a corner il which it is desired to brace.

The teeth and projections are preferably formed to insure that the device is positioned the corner.. 7

Another form of construction for the teeth 11 and the angular extensions 27 of the staple 26 is illustrated in Figure 4.

While Ihave indicated that the lip 0 tions 8 and '9 are joined preferably to the p 7 plate 6', this jointure maybe omitted, for
