This invention relates to scaffolds, and particularly to brackets for use in constructing scaffolds, and to the method of constructing the brackets.

In the operation of building houses, it is generally necessary to erect scaffolds around the outside walls thereof, as they are being built up, for use in supporting floor boards for workmen and material. Ordinarily wooden cleats are attached to the sides of the walls, and cross bars extended from the cleats outward to some spaced framework, and boards laid over the bars which are usually formed of wooden scantlings. Such construction requires much time and labor, and owing to defects in the wooden cleats and cross bars and carelessness of the workmen, the cleats and bars may split or break or otherwise loosen, which results in collapse of the scaffold and frequently injury or death to the workmen. In such forms of construction all the lumber used in the scaffolds is generally abandoned when the scaffolds are torn down on the completion of the work adjacent thereto.

It is therefore an object of this invention to provide brackets of relatively light weight and economically formed, which may be quickly and securely attached to the walls of a building, and be and remain safe for the duration of the requirements of the scaffold, and which may be then removed without injury thereto and saved for future use indefinitely.

A particular object of the invention is to construct such brackets from relatively light weight angle iron of standard formations, and to form the bars of angle iron into the desired shapes integrally, for attachment to walls and outer posts, for safely supporting floor boards, for completing the frames of scaffolds, for economy and safety.

With these and other objects to be hereinafter stated, I have illustratively exemplified my invention by the accompanying drawings, of which:

Figure 1 is front elevation of a completed scaffold adjacent to a house, and formed with the brackets herein mentioned.

Figure 2 is a side elevation of structure shown in Fig. 1.

Figure 3 is an enlarged detail plan view of one of the brackets.

Figure 4 is a side view of the bracket, and

Figure 5, is a rear view of the bnacket feet, taken on line 55 of Fig. 3.

Like characters on the different figures, represent like parts. The letter A indicates generally one of the brackets, supported for use in horizontal position by a post B perpendicularly disposed in and through a yoke or rectangular neck b, in the outer portion of the bracket, for supporting floor planks C for workmen and material for construction or repair of a building D. As the construction of the bracket is most important, the parts of the same will be further explained.

The bracket is preferably formed from an original straight bar of angle iron of suitable weight and dimensions for the purpose desired, being suitably bent and formed in shapes for best advantageous uses. Numeral 6 represents one of the flanges called for convenience the top flange, and 1 represents the lower flange forming the angle iron, the completed shape being generally in form of an A-irame. The narrow end or head of the bracket is bent into rectangular form for the neck b, and post, or a pair of scantlings being nailed together for convenience instead of a solid post, the sides of the neck shown as 8 and 9 and the outer cross section of wall as It. Holes for nails shown as l l are provided through the walls for supporting the outer end of the bracket to the post, while being used on a building, but the nails may be readily withdrawn when the building is completed, or for moving the bracket to another position.

The legs of the frame are extended back from the head in divergent lines for bracing advantages laterally, and the foot ends are split along the junction of the flanges 0r Webs 6 and I suflicient distances to provide for feet as l2 and 13 for connecting with the walls of the house. Foot l2 being part of web 6 is bent upward at right angles to the plane of the legs and. provided with nail holes 14 for suitable nails to be driven therethrough into the side walls of the building. It will be understood that as soon as a nail is driven into the top hole that the bracket will be sustained horizontal by the lower end or heel of the foot l2 acting as a fulcrum against the wall, until the post can be attached through the outer neck, thus facilitating positioning of the brackets in elevated positions for scaffold floors. The other or lower portion of the split bar, is bent laterally substantially at right angles, and provided with holes l5 for additional nails therethrough whereby all lateral movement of the bracket is effectually prevented. In order to apply the bracket near the end of the house and scaffold, the feet l3 are preferably turned inward toward each other.

In order to facilitate the forming of the rectangular head, it is advisable to sever the top flange 6 at a point to conform with an outer corner thereof at the line indicated by Hi, then when the side portion is bent down at right angles 3 the edge formerly adjoining I! will appear at the point indicated by line 11, which will thus leave a V shaped space between the edges, which is preferably closed by a wedge 18 to be electrically welded along its edges at the points [6 and IT. This provides a continuous unbroken top flange 6 and a continuous lower flange 1, for providing a maximum of strength to the bracket with a relatively light weight, for transportation and in the operation of attaching the feet to the house walls, whereby the brackets will be held horizontal for supporting floor boards or planks 0.

Having described my invention I claim:

In a bracket for scaffolds, comprising a bar of angle iron built into a plurality of angular lines integrally arranged in an A frame for horizontal attachment to the sides of a building, and having a top web horizontally disposed around the top of the frame for supporting floor boards for workmen and material for the building, and having another web vertically positioned beneath the top web for rigidly supporting a relatively heavy load, by a relatively light weight of metal for the bracket, the outer closed end of the frame being 4 rectangularly shaped for a seat for a post for supporting the outer end of the bracket, feet on the inner ends of the frame one being turned upward at right angles to the top of the bracket, and the other being turned horizontally substantially at right angles with the edges of the bracket, both said feet being provided with holes therethrough for nails for attachment of the feet to the outer walls of said building.
