SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 553,497, dated J anuary 21, 1896.

Serial No. 439,800. (No model.)

To all whom t may conceive:

Be it known that I, THOMAS CoEscADEN, a citizen of the UnitedStates, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Shelfdrackets, of which the following is a specification.

My invention relates to improvements in shelf-brackets, and the chief objects of my improvement are economy of product and general eiiiciency of the article.

In the accompanying drawings, Figure l is a side elevation of my shelf-bracket. Fig. 2 is a sectional view of the saine on the line 0:, Fig. l. Fig. 3 is a side elevation, with portions broken away to redueethe length, of the blank for the wall and shelf plates. Fig. et is a sectional view of the bracket on the line y y, Fig. l. Fig. 5 is a side elevation of the lower end, showing a slight modification; and Fig. G is a side elevation of a similar portion, showing another modification.

A designates the wall-plate, B the shelfplate, and C the brace. I form the wall and shelf plates from a rolled metal bar that is T-shaped in cross-section, using the top of the T or the broad member for the plates proper, while the shorter central member or upright portion of the T-bar forms a strengthening-rib 7. The contour of the wall and shelf plates as viewed on either of their broad sides may be of any ordinary design. These plates will also be provided with the ordinary screw-holes, as at S, Fig. 2. I iirstblank out these plates from a long T-bar, thereby giving the proper length and the desired form as viewed on the broad side. I also blank out the rib by cutting a right angular notch 0, Fig. 3, at the point designed for the junction of the wall and shelf plates, remove the rib for a short distance from the outer ends of said plates, as at 10 10, Fig. 3, and also prepare the rib for the abutting edges of the brace, as at 1l and 12. The bar is then bent at the point having the notch 9 to bring the wall and shelf plates at right angles to each other, when the notch is closed and forms the miter-seam I6, Fig. l.

I form the brace C preferably from a straight bar of metal of a thickness equal to that of the rib 7 by bending to give the desired curvature and cutting its ends to match the other parts, but the brace may be eut out by dies if desired. For the purpose of illustra tion I have shown the opposite ends of the brace as differently fitted, but in practice I prefer to make both ends alike. At the upper end of the brace there is a dovetailshaped tenon 153, which fits into a recess of corresponding form in the rib 7, said recess being shown without the tenon at l2 in Fig. 3. The brace has its edge abutting against the edge of the rib and is secured against lateral displacement by a rivet la, the body of which rivet passes through a round hole formed partly in the rib and partly in the brace while both of its ends are headed, as shown in Figs. I and el. If desired, instead of putting this rivet through the end of the dovetailed tenon I3 it may be put through any other part where the brace and rib come together-as, for example, in the hole 14:, Fig. 5, or the hole 15, Fig. G.

The lower end of the brace C, as shown in Figs. l and 5, is provided with a tenon 17, which passes through a hole in the wall-plate A, said tenon being riveted down or headed to hold it in place. The lower end of the rib 7 is trimmed off, as at 1l, Fig. 5, to fit and abut against the upper edge of the brace, as shown in Fig. l. If desired, however, instead of cutting the rib oii with a slanting edge to fit the normal edge of the brace C the abutting portion of the edge of both the rib and brace may be cut to match each other, as shown in Fig. 5, and in either case a rivet, hole may be provided at their junction, as at 14, Fig. 5, and the parts further secured by a rivet placed in said hole and headed at each end. IVhile I have specified these different forms of fastening as at the upper and lower ends of the brace, it is evident that all of these forms are applicable to either end of the brace.

By my improvements I form a bracket from a rolled T-shaped bar and a brace by cutting, bending, and securing together, thereby pro* ducingabracket at asmall cost. The bracket when produced is neat and attractive in appearance and is of superior strength.

I claim as my inventionl. In a shelf bracket the plates having the strengthening rib 7, the brace C having one edge abutting against the edge of said rib IOO and the rivet 14 headed at each end and passing through a hole formed partly in said rib and partly in said brace, substantially as described and for the purpose specified.

2.v In a shelf bracket the plates having the strengthening rib 7 with an angular notch therein, the brace C having one edge abutting against the edge of said rib with an angular tenon Within said notch and the laterally holding` rivet, substantially as described and for the purpose speciiied.

3. A shelf bracket, the Wall and shelf plates of which are formed from a seamless rolled THOMAS CORSCADEN.
