v SAMUEL MARTIN, OF MONTPELIER, OHIO.

SCA'FFOLDlNG-BRAGKET.

SPECIFICATION forming part of Letters Patent No. 352,420, dated November 9, 1886. Application filed August 7, 1886. Serial No. 210,281. No model To all whom it may concern Be it known that I, SAMUEL MARTIN, a citizen of the United States,andaresident of Montpelier, in the county of Williams and State of Ohio, have invented certain new and useful Improvements in Scaffolding-Brackets and 1 do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which Figure l is a side view of my improved scaffolding-bracket,showing it applied. Fig. 2 is a'similar view seen from the other side and Fig. 3 is a view of the bracket folded up for storage or transportation.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to brackets for supporting scaffolding and it consists in the improved construction and combination of parts of a folding bracket, which may be secured to the studding of a frame building for the purpose of supporting scaffolding during weather-boarding, or to any other upright supports, and which may be reversed and folded up, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the horizontal arm of the bracket, which arm supports the boards of the scaffold, and is provided at its inner end with a hook, B, having its point bent to one side and again outward, enabling it to engage the inner side of the studding to which it is secured, the point of the hook entering the inner face of the studding. An inclined brace, O, is pivoted near the outer end of the horizontal arm upon a suitable bolt, D, and the lower end of this brace is provided with a bolt, E, passing through a perforation, F, in the same, and provided with a'nut, G, and suitable washers, and this nutted bolt may be inserted through one of a series of perforations, H, near thelower end of a vertical arm, I, and be secured in the same by the nut. The upper end of the vertical arm is formed with a loop, J, formed preferably by a strap of metal, and one side of this loop, through which the hooked end of the horizontal arm may It will now be seen-that when the hooked end of the horizontal arm isplaced so as to bear with the hook into the inner face of the studding the loop of the vertical arm may be forced toward the outer face of the studding, and the pointed end of the pivoted bar may be driven into that face of the studding, securing the bracket from sliding or turning upon the studding,the weight of the scaffolding,which rests upon the horizontal arm,drawing the said arm outward, and forcing the hook into the studding on account of the lower end of the brace bearing against the side of the studding or building through the vertical arm.

By adjusting the lower end of the brace with its nutted bolt in the perforations at the lower end of the vertical arm the bracket may be adjusted to engage studding of different thickness,tl1e space between the pivoted point upon the loop and the end of the hook being in creased as the end of the brace and its bolt is moved downward in the perforations, and vice versa.

- By withdrawing the hooked end of the horizontal arm from the loop and swinging the said arm and the brace around,-turn ing them upon their pivotal bolts, and by again inserting the hooked end from the opposite side of the loop, and by reversing the point upon the loop, the bracket may be reversed, placing all parts in a position opposite to theposition in which they were formerly.

Having thus described my invention,I claim and desire to secure by Letters Patent of the United States- In a bracket for supporting scaffolding, the combination of a horizontal arm having a hook at its inner end, a brace pivoted upon a bolt to the outer end of the horizontal arm and having a nutted bolt at its lower end, and a vertical arm having a series of perforations at its lower por ion for the bolt of the brace, and having a loop at its upper end for the passage of the hooked end of the horizontal arm, and provided with a pointed bar pivoted upon the side of the hook, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

SAMUEL MARTIN.
