PATENT FFICE.
THOMAS CORSCADEN, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO TH STANLEY WORKS, OF SAME PLACE.
SHEET-METAL SHELF-BRACKET.
SPECIFICATION forming part of Letters Patent No. 577,977, dated March 2, 1897.
Application filed December 8,1893. Serial No. 493,154. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS CORSCADEN, 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 Sheet-Metal Shelf- Brackets, of which the following is a specification.
My invention relates to improvements in sheet-metal brackets, and the chief objects of my improvement are simplicity and economy in construction and general efficiency of the article.
In the accompanying drawings, Figure 1 is a side elevation of my bracket. Fig. 2 is a front elevation of the same. Fig. 3 is a plan View of two blanks forthe shelf-arm of my bracket. Fig. 4 is a plan view of a blank for a wall and shelf arm of my bracket when formed of a single piece, and Fig. 5 is an enlarged front view of the upper portion of my bracket in a slightly-modified form.
I form the wall-plates 5 and shelf-plates 6 integral with the strengthening plates or ribs '7 and 8. These are first blanked out, as shown in Fig. 3, in which the wall-plates and integral strengthening-ribs are cut out from each other, as shown, and in like manner the shelf-plates and integral strengthening-ribs are out from another piece of sheet metal. These blanks are then bent longitudinally to throw the shelf and wall plate portions at substantially right angles to the strengtheningrib, as shown. I then let the butt-ends of the stren gthening-ribs lap by each other, as shown in Figs. 1 and 2, and mechanically secure them together in any proper manner, as, for example, by means of the rivets 9. When the wall and shelf plates are formed of separate pieces, the shelf-plate may lap over the upper end of the wall-plate, as shown in Fig. 1.
Instead of forming them of two pieces the wall and shelfplates may be formed in one piece, as shown in Fig. 4, and the blank slit in the middle portion on the line 10 to the full distance of the width of the strengtheningribs, and the wall and shelf plate portions may be bent at right angles to each other at their junction in alinement with the slit 10, and the strengthening-ribs may be bent at right angles to the wall and shelf plates, letting the butt-ends of the shelf-plates lap by each other, as shown in Fig. 1, when they may be mechanically secured, as above described.
In Fig. 5 I have shown in front view the upper end of my bracket with the wall-plate 5 and shelf-plate 6 formed integral with the strengthening-ribs '7 and 8 in the manner before described, but in order to widen the wallplate I have secured thereto an additional wall-plate 5 and strengthening-rib 7, the same being mechanically secured together at their junction by means of rivets 9, as before described, thereby forming a bracket With a wide wall-plate and a narrower shelf-plate.
I am aware that a prior patent shows and describes a sheet-metal bracket the wall and shelf plates of which are formed of a single strip of metal having a flattened projecting fold extending longitudinally along-the middle in the form of a hollow web, which web has a V-shaped miter-notch cut out at the junction of the wall and shelf plates. The strip is then bent. to bring the wall and shelf plates at a right angle to each other and also bring the mitered edges together, and the bracket is strengthened by the insertion into the hollow of the web at that point of an L-shaped plate of metal secured by rivets through the web, and the same is hereby disclaimed.
I claim as my invention- A sheet-metal bracket consisting of wall and shelf plates and flat integral strengthenin g-ribs tapered substantially from end to end, each of said plates and its rib being cut from sheet metal and bent on a single longitudinal line between its out edges to the form of an L shape in cross-section, the two tapering strengthening-ribs being arranged with their wider ends at the angle of the wall and shelf plates, with their said wider ends mechanically secured together and with the tapered cut outer edge of each rib extending from their junction to the narrow ends of said ribs, substantially as described and for the purpose specified.
