l This invention relates to scaffold brackets. y

' rIhe principal 'provide a scaffold bracket which is safe and easily put into use and removed When not Y in use.

A further object of the invention is to provide a scaffold bracket that maybe folded when not in use.

A further `object is to provide a lscaffold f 10 bracket that may be put in position `in the construction of a building Without cutting `or leaving holes. in the sheathing-in order to place a scaffold bracket in position.

A still further object is to provide a de- 415` vice With a locking brace member which provides a means for enabling the bracket to be folded When not in use. Y

With the foregoing andv other objects in view Which Will appear as the description invention resides in the combination and arrangement of parts and ink the details of construction hereinafter de-` scribed and claimed, itbei'ng understood that changes in the'precise embodiment of the invention herein disclosed,can be made Within the scope of What isy claimed, Without departingk from the spirit of the invention. The invention isfillustrated inthe accompanying drawings, wherein f e Figure 1 is a top plan view of .the device in position With reference' to a Wall. Y Figure 2 is a side elevation in position With reference to a Wall. v Y Figure 3 is a detailed sectional vievv taken 85 on line 3-3 of Figure y2.

Figure 4'is a view of folded.

By referring to the drawings, it will be seen that Ihave shown a studding 1. In ordinary building construction sheathing 2 Y is nailed or secured to the studding 1.y At positions on the Wall Wherev it is desired to place the scaffold bracket,tliesheathing 2 is placed so as to leave a slight opening-3 the device When for the insertion of .a securing hook 4 vWhich functions With the Astudding 1. It Will be seen by referring to Figure 2 that this securing hook 4 is an extension of an upper porl tion 5 of an angle iron 6,.Which forms ythe [3^ horizontal rest for staging planks -7,upon

This uprightf)V is 'utilized to prevent'.the'stagingv planks 7 fromy slippinggoutvvardly beyond the extreme outer end .8 of theaiigleiro'n ,6. Hinged tothisangle iron 6by means ofa pivot pin 10, I have provided a vertical anglev iron 11 vvhichis provided with a curved lip-. l

per end 12. The opening. of this curvedVv upper end 1,2 is toprovidespace suflicent to push the securing hook 4 so that itv may funetionwith a studv 1, when the' device @is in a folded position ask shown in Figure 4.L It will alsobe seen that this V.angle iron.

angles to the vertical angle iron.11,I have provided a locking brace memberviconsisting of parts 15 anvdl. These

parts

15 and 16 are formed of angle iron. Thepartlis 6 by `means of a'pivot pin-18 at kpoint 19..

The part 1 6 is secured to a Vvertical vangle member T ll by means ,ofapivot rpinV 20l at Ilhave; provided a slot V22 formed inthe part 15 through Which` functions a slidable bolt or pivot pin 23 kwhich is secured to an` inner end 24 of the part 16. The extreme l inner end 25 yof the part 15y is bifurcatedpro- 1 vidingme'ans for functioning With lug 26 which issecured to the part 16 atk point 27.

'Itj Will also be seen that; the inner end of the part15 provided with a dependent lflange 28 which functions With an outer edge 29,

lof the'part 16, in order to hold the assembledparts lkand 16 in rigid alinement in reference' to each other. v n

4 In folding up the device, the eXtreme outer end 8 is liftedup thus alloWingthe part V 15 to free the bifurcated end 25, lug `26 so jsecu'redat` an upper endj17 to the vangle iron i that these parts may be folded inwardly towards the parts to Which the outer ends of the same are hinged. By referring to Figure 3, it Will be seen that there has been provided a notch 30 which is formed on the part 15 in such a position that when the part 15 is folded up against the part 16 the lug 26 functions Within the notch 30.

By referring to Figure 2, it Will be seen that at a point Where the securing hook passes through the opening 3, it is slightly thicker in order to provide against possibility of bending or breaking at this point- When under strain.

What I claim is 1. In a collapsible scaffold bracket a vertical angle iron having a curved upper portion, a horizontal angle iron having its inner endpivoted to said vertical angle iron and an extension at its outer end forming a securing hook, a two-part locking brace member, a pin pivotally securing the inner ends of said brace member parts, one of said brace member parts having a slot slidably engaged by said pin, and aL lug adjacent the inner end of the other brace member part, the first named brace member' part having a' bifurcated end adapted to engage the lug to hold the brace member parts in locked" position When the device is opened in position for use. Y

2. In a device of the class described, a vertical member having a curved upper end, a horizontal member pivoted to said curved end, a securing hook member formed as an extension of said horizontal member for the purpose of engaging a studding or upright of a building, a two-part lock brace member pivoted to the outer end of said horizontal member and to the lower-end of said vertical member, a pin pivotally connecting the parts of said brace member, one of said parts having a slot, a flange and a bifurcated end and the other part having a lug to engage in said bifurcated end, said pin, slot, flange, lug and bifurcated end cooperating tolock the brace parts in an extended and aligned position. f

In testimony whereof I afliX my signature.
