LADDER BRACKET.

Application filed April 1, 1925. Serial No. 19,772.

To all whom, it may concern:

Be it known that 1, ANDREW Bowen, a citizen of the United States, residing at Rockford, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Ladder Brackets, of which the following is a specification.

My invention'relates to improvements in ladder brackets, and its objects are: first, to provide a'ladder bracket that may be readily adjusted for use upon any make of ladder; second, to provide a ladder bracket that may be reaily adjusted for supporting a wide, or a narrow platform or staging, and, third, to provide a. ladder bracket that may be readily folded in small space for storing,

it away.

' I attain these objects by the mechanism and construction of parts shown in the accompanying drawing, in which Fig. 1 is a side elevation of the upper part of a ladder with one side removed to show the applica- 7 tion of my bracket, and showing the ladder supported upon a I wall. Fig. 2 is a plan of the bracket removed from the ladder and folded for storing away. Fig. 3 is a plan or end view of a ladder with my bracket in place, and Fig. 4 is a plan of the part of the bracket that supports the free end of the bracket rail or beam.

Similar reference characters indicate similarparts throughout the several views.

In the construction of this bracket I make 7 use of a projecting beam or rail 3, one end of which is pivotally mounted between the ends of the side bars that form the brace 6. This brace is divided at the end opposite the connection with the beam 3, as at 6, and so formed that the two ends, 6'6, will safely engage. the rung 7 of the ladder, as indicated in Fig. 1 in such a manner that it will safely support the outer end of the beam 3. To support the other end of the beam 3, upon the ladder rung 7 I provide a second bracket t having the two sides far enough apart, and properly provided with,supportingpins '0 and (Z to properly receive and support the beam, as follows: the back ends of the sides 4-4: are bent outward at right angles, then bent backwards, as at 5, and the extreme ends are made into hooks that may be passed over the ladder rung, as shown in Fig. 1. Before this bracket is connected with the ladder rung it is placed upon the beam 3 with the beam resting upon the supporting pin (Z, and the pin 0 passed into one ofthe notches Z) in the beam 3 in position to give the proper, i

or desired length or distance the beam is to extend outwardly from the ladder.

At 6 I have shown supporting'block placed between the sides of the brace 6, at the end next to the ladder, which block is secured in place vby the rivet f, as shown in Fig. 2.

It is to be understood that 1 represents the side of a wall upon which'the ladder is supported by means of thehooks 8 passing over the top of the wall, and 2 represents the ladder stiles or sides. 7 v i The dotted lines above the beam 3, in

Fig. 1, represent the outlines of the staging plank as supported bythe bracket.

The reason for placing several notches, as

I), in the upper edge of the beam 3 is that I different makes of ladders place the' -rungs dilferent distances apart, which may require the placing of the beam 3 in different positions upon the ladder, and another reason for this is that when a ladder is positioned at an angle supported' at the upper end against the wall, the beam of the bracket must be arranged accordingly so as to insure a level support for the staging plank,'r epresented by the dotted lines in Fig. 1.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is: I r

In a bracket for supporting a platform upon a ladder, a supporting bar, a brace pivotally connected at one end to the bar.

and having its other end provided with notches to engage ladder rung, the bar having forwardly inclined notches in. its upper edge, a second bracket formed of two parallel bars spaced apart and having their front ends bent upwardly, a pin connected with said ends holding them together and positionedto enter anyone of said inclined notches, a second pin connecting the middle portions of said parallel bars and positioned to pass under said supporting bar rearwarch ly of the first mentioned pin, the rear ends of said parallel barsbeing bent outwardly, then rearwardly, then downwardly to form hooks to engage the ends of a ladder rung.

ANDREW'BOWER.
