THOMAS CORSCADEN, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE STANLEY FORKS, OF SAME PLACE.

SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 476,520, dated June 7, 1892.

Application filed December 15, 1890. Serial No. 374,682. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS CoRscADnN, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shelf-Brackets, of which the following is a specification.

My invention relates to improvements in shelf-brackets; and the objects of myimprovements are to construct a shelf-bracket from a single piece of sheet metal, to construct the same at a small cost, and to so shape the blank and inner corner of the bracket as to economize in cutting the same from a metal plate.

In the accompanying drawings, Figure l is a side elevation of my improved bracket. Fig. 2 is a plan View of the same, and Fig. 3 is a side view of one of the blanks on a smaller scale, together with a series of blanks in broken lines illustrating the manner of cutting the same from a plate or sheet of metal.

A designates the body portion of the bracket, which consists of a flat plate or sheet of metal standing edgewise and forming two arms, the arm 4.- being designed for the vertical or wall arm and the arm 5 being the shelfarm. Each of these arms are provided with any suitable number of lugs 6, which are'perforated to receive screws for securing the bracket in place and securing the shelf to the bracket. These lugs are out integral with the body portion from a flat piece of sheet metal, as shown in Fig. 3, and the metal is slit :1. short distance into the body portion at the junction of the lugs and body to facilitate bending. The lugs are perforated and bent at right angles to the body portion, some in one direction and some in another, so that said lugs stand at right angles to said body portion, all as shown in Figs. 1 and 2. I form the junction of the arms at and 5 on their inner edge with a right-angular notch 7 in the middle, and upon each side of the same a curved or rounded notch 8, corresponding to the curve of the lugs 6. The position of said rounded notches with reference to the rightangular notch 7 is the same as that of the outer corner of the two arms and the lugs 6 6, which are nearest thereto and into which the blank for said corner and lugs will fit, as illus- 5o trated by the diagram in broken lines in Fig.

3. By thus forming the inner edge of the body of the bracket at the point between its two arms of the same contour as the outer edge of the blank from which the bracket is made I produce a neat and ornamental eifect, and am enabled to cut the one blank from the inside of another, as illustrated in Fig. 3. The parallel broken lines 9 9 indicate the edge of the sheet or plate from which the blanks are out. By this construction there is but little waste of stock.

l/Vhile I have described and shown the screw-holes as formed in lugs, which, in fact, are short flanges, it is evidentthat the lugs nearest the outer end of each arm may be made wider, if desired, or even the two outer lugs could be made in one continuous flange without cutting out the metal between them. This would result only in turning the stock which in the construction shown goes into scrap or Waste into the finished article. A glance of Fig. 3 shows that there is stock enough between the two adjacent blanks to form said flanges or wider lugs, if desired.

I claim as my inveniton The herein-described sheet-metal bracket, consisting of a plate-like body portion with screw-hole lugs turned edgewise therefrom at its outer edge and having its inner edge at 80 the point between its two arms provided with a central right-angular notch and a rounded notch at each side of the same, substantially as described, and for the purpose specified.

THOMAS CORSCADEN.
