SPECIFICATION forming part of Letters Patent N0. 754,105, dated March 8, 1904.

Application filed November 4, 1903. Serial No. 179,836. (No model.)

mour, in the county of New Haven and State of Connecticut, have invented a new and useful Folding Bracket, of which the following is p a specification.

This invention relates generally to brackets for the use of carpenters and builders, and more particularly to a folding bracket which can be quickly and easily set up or taken down and one which when properly set up and connected to a building or-structur'e cannot possibly collapse or become disjointed.

Another object of the invention is to provide a bracket of this kind which can be folded into a very small space, and a still further object is to provide a bracket formed of angleiron, thereby providing an exceedingly strong and light bracket.

With these objects in view theinvention consists in the novel features of construction hereinafter fully described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View showing the practical application of my invention. Fig. 2 is a side elevation of the bracket set up and ready for use. Fig. 3 is a side View of the bracket folded. Fig. 4 is a similar view of the bracket folded. Fig. 5 is a detail perspective View showing the manner of connecting the upright horizontal arms of the bracket, and Fig. 6 is a detail sectional view taken on the line 6 6 of Fig. 2.

In constructing a bracket in accordance with my invention I employ a horizontal arm A, upright arm B, and the oblique brace-arm C, all of said arms being constructed of angleiron. The upper end of the oblique arm C is pivotally connected to the outer end of the horizontal arm A by means of a rivet D, passing through the abutting flanges of the said arms. At the extreme outer end of the arm A the flanges of the angle-iron are pressed together and turned up,as shown at E, thereby providing a stop to prevent the scaflold-timbers F sliding off the horizontal arm A. The lower end of the oblique arm C is pivotally connected to the lower end of the upright arm B by means of a rivet G, the flanges of the oblique member being pressed together, as shown at C, and inserted between the flanges of the upright member, said flanges being also pressed in parallel relation at the extreme end, as shown at B. This construction greatly stiflens the arms at their ends and renders them stronger at the pivotal points, which are the points where the greater strains occur.

A rod H is secured to the rear end of the horizontal arm A, said rod being adapted to be passed through an opening B produced in the upper end of the upright arm, and the outer or rear end of this rod is threaded, as shown at H, and is adapted to have a nut I screwed thereon, said rod being first passed through the end of the upright arm,and then through the structure against which it is intended to arrange the bracket. The nut I is then screwed upon the threaded end of the rod, and the bracket will be securely fastened in place and all danger of collapse or becoming disjointed entirely avoided. The scaffolding-timbers F can then be arranged '1 on the horizontal arm of the bracket. When it is desired to move the bracket, it is only necessary to rembve the nut and withdraw the rod, and after the rod has been withdrawn from the structure it can be withdrawn from the upright arm,and the horizontal arm can then be folded down upon the oblique arm and then the two folded'close into the upright arm, as most clearly shown in Figs. 3 and 4:.

It will thus be seen that I provide an exceedingly simple, light, and durable construe-- tion of folding bracket which can be quickly and easily set up or taken down and one which can be folded into a Very small space when not in use.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent. is

1. A folding bracket formed of angle-iron and comprising the horizontal arm, the upright arm and oblique arm, the upper end of the oblique arm being pivotally connected to the outer end of the horizontal arm, and the lower end of the oblique arm being pivotally con- -nected to the lower end of the upright arm,

the flanges of the oblique arm being pressed together at the lower end and arranged between the flanges of the upright member, the flanges of said upright member being pressed into parallel relation at the lower end, and the rod connected to the rear or inner end of the horizontal arm and adapted to pass through the opening produced in the upright member adjacent the upper end, as set forth.

2. A folding bracket formed of angle-iron comprising the horizontal arm, the upright arm and oblique arm, the outer end of the horizontal arm being turned upwardly, the inner end of said arm having a rearwardlyprojecting rod attached thereto, the rear end of said rod being threaded, the upper end of LOUIS W. TUCKER.
