Application filed October 25, 1828. Serial No. 670,648.

This invention relates to improvements in scaffold brackets and has for its principal object the production of a simple and efficient means for securing said scaffold bracket to walls of buildings.

Another object of the invention is to provide a scaffold bracket that is to be used in constructing buildings where the wall is of brick and more particularly buildings known to the trade as brick veneer buildings; that is, where the construction of the walls consist of a wooden frame portion having a single layer of brick veneer on the outer surface of said wooden construction.

1 still further object of the invention is to provide a bracket whichis easily re moved from the wall after the brick has been laid.

With the foregoing andother objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a side elevation of the device showing a section of a wall to which the bracket is attached.

Figure 2 is a detail perspective view showing securing means for said bracket.

Figure 3 is a perspective view showing a modification of a horizontal support member of the bracket.

Figure 4 is a front elevation of a portion of a wall showing a securing arm in cross section.

Figure 5 is a portion of a wall showing the modified form of horizontal support member of Fig. 3 in cross section.

Referring to the drawing which constitutes a part of the specification, like reference numerals are used throughout various figures of the drawing.

By referring to Figure 1 it may be seen that I have provided a scaffold bracket having a horizontal support member 1 for the purpose of supporting a platform upon which workmen may stand. This support member is provided with an upturned end 2 for the purpose of preventing said platform from slipping off the same. This support member which is preferably made of angle iron or steel is provided with a tapering securing arm 3 which normally functions with a wall 4 and has an end 5 projecting through-said wall 1 in order that a U- shaped retaining member 6 may be used to hold the bracket in desired relation to the wall 4-.

By referring to Figure 2 it will be seen that this U-shaped retaining member 6 is provided with a plurality of central openings 7 through any one ofwhich the end 5 may project. The end 5 is provided with a plurality of holes 8 spaced apart through which a key pin 9 is inserted when the U- shaped retaining member 6 is placed in position. It will be seen that the key pin 9 passes through holes 10 of the member 6 as well as throiiigh the hole 8 formed in the end It is common in building frame buildings or in building brick veneer build.- ings to use vertical studdings 11 to which sheathing 12 is secured. The brick is then laid adjacent to the sheathing 12. It will be seen that the U-shaped retaining member 6 extends outwardly so as to rest upon said vertical studdings 11. When it is desired to place a bracket at a corner of a building under construction the end 5 is inserted through the outer central opening 7 so that the end 13 or 14 may rest upon the corner studding 11.

By referring to Figure 1 it will be seen that the bracket comprises the horizontal support member 1 provided with a downwardly extending angle member 15, a brace angle member 16 and a vertical reenforcing angle member 17 which is secured to the horizontal support member 1 at point 18 and to the brace angle member 16 at point 19. The horizontal support member 1 has a lower flange 20 having an end 21 which projects into the wall 4:, a distance equal to the width of the bricks in the wall 1. This end 21 is formed so that an obtuse angle 22 is formed when considering the tapering securing arm 3 and the edge 23 as forming the angle.

By referring to Figure 1 it will be readily seen that the end 21 and the tapering securing arm 3 fit easily within the mortar seams 2 1.

By referring to Figures 3 and 5 it will be seen that a T-shaped horizontal support member 25 may be used in place of the angle 1ijron forming the horizontal support memhat I claim is 1. In a device of the character described comprising a horizontal member having its inner end tapering and adapted to extend through the mortar between two horizontal faces of the bricks of a wall, means detachably secured to the inner end of the tapering portion of the body on the inside of the wall and adapted to prevent the outward movement thereof, a brace carried by the horizontal member and engaging the outer face of the wall, and said horizontal member having a vertical portion extending through the mortar between the vertical end walls of the bricks, and terminating at a point in beyond the inner faces of the bricks.

2. In a device of the character described comprising a horizontal member having its inner end tapering and adapted to extend through the mortar between two horizontal faces of the bricks of a Wall, and having openings therethrough, a U-shaped plate having an opening to receive the tapering inner end of the member and having oppositely disposed openings adapted to receive a key which passes through one of the openings in the horizontal member for locking the same on the tapered inner end of the member on the inside of the wall, and adapted to prevent the outward movement thereof, a brace carried by the horizontal member and engaging the outer face of the wall, and said horizontal member having a vertical portion extending through the mortar between the vertical end walls of the bricks and having a beveled inner face ter minating at a point in beyond the inner faces of the bricks.

3. In a device of the character described comprising a horizontal member having its outer end turned upwardly and its inner end tapering, and adapted to extend through the mortar between the two horizontal faces of the bricks of a wall, and having vertical openings therein, a member having an open-- ing through which the tapering end extends, and a key for locking the same thereon by passing through one of the openings in the horizontal member and adapted to prevent the outward movement of said horizontal member, a brace carried by the horizontal member and engaging the outer faceof the wall, and said horizontal member having a vertical portion extending through the mortar between the vertical end walls of the bricks, and having its inner end beveled and terminating at a point in beyond the inner faces of the bricks.

In testimony whereof I afiix my signature.
