To all whom it may concern:
Be it known that I, Samuel F. Wray, a citizen of the United States, residing at Elwood, in the county of Madison and State of Indiana, 5 have invented certain new and useful Improvements in Corner Scaffold-Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to i o which it appertains to make and use the same.
My invention relates ’to corner scaffoldbrackets.
The object of the present invention is the provision of an improved, cheapened, and i5 simplified corn er-bracket of the class described which shall be adapted for quick attachment and removal and afford a stron g and durable support.
The invention consists of certain novel fea2o tures and combinations, as will appear more fully hereinafter.
In the accompanying drawings, Figure 1 represents my improved corner-bracket in use; Fig. 2, atop perspective view with one of 25 the brackets removed from the angle-iron; Fig. 3,.a side elevation of one of the brackets, and Fig. 4 a view of my improved lag-screw.
A represents the corner-post of the scaffold, and B the cross-braces. The angle-iron 1 is 30 preferably of half-inch bar-iron and provided at its angle with a hole 2, through which passes my improved lag-screw, to be described later on. The arms of this angle-iron are provided with vertically-disposed pockets 3, formed by 35 a bent-up strap of metal 4, suitably fastened in position. If preferred, these pockets might be formed by bending up the arm of the angle-iron.
The rear face of the triangular wooden 40 bracket 5 is provided with a hook 6, which is adapted to snugly fit the pocket 3 when the bracket is in position.
My improved lag-screw for fastening the angle-iron in position consists of threaded body or shank 7, which is provided with a 45 longheads, forming, as it were, a crank,which extends at right angles to the shank and is provided with a crank-handle 9. After the angle-iron has been placed in position the lagscrew is inserted in the hole 2 and driven par- 50 tially in the corner-post A. It may then be screwed into proper position by turning the crank-handle. The hooks on the brackets are next inserted in their pockets and the crossbraces properly lashed or fastened in position 55 on the shelves of the brackets.
