SHINGLINGr-BRACKET.

Specification of Letters Patent.

Patented Nov. 12, 1912.

1 Application filed September 3, 1910. Serial No. 580,352.

To all whom it may concern:

Be it known that I, FRANK P. HOWARD, a citizen of the United States, residing at East Brownfield, in the county of Oxford and State of Maine, have invented certain new and useful Improvements in Shingling- Brackets, of which the following is a specificat-ion.

My invention relates to shingling brackets designed to support scafiolding on a roof, and has for its primary object to provide a strong, simple bracket that may be adjusted for use on roofs of different angles, and also on a vertical wall.

A further object is to provide improved means for attaching the bracket to the roof.

To these ends my invention consists in the construction and combination of parts hereinafter described, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation showing my improved bracket in the position which it occupies on a roof; Fig. 2 is a similar View showing the bracket as applied to a vertical wall; Fig. 3 is a front elevation of the bracketas shown in Fig. 2; Fig. i is a detailed front view on an enlarged scale of the upper end of the bracket and supporting means therefor; and, Fig. 5 is a similar view, the bracket being shown in shifted position.

Referring to the drawings in detail, my improved bracket comprises a base 1 which is adapted to rest against the roof .or wall of a building. To the upper end of the base 1 is pivoted at 3 one end of a supporting bar 2, the other end of which is pivoted at 1 to one end of a strut or brace 5, the other end of which is provided with a tenon 6. The upper end of the base plate is provided with a notch or mortise l in which the end of the supporting bar 2 works.

To the rear side of the upper end of the base 1 is secured a suporting plate 7 which is arranged to lie flush with the back face of the base. This plate 7 is provided with an irregular shaped opening 8 having a curved contour and provided with three notches 9 extending radially outward therefrom. One of these notches is centrally arranged and the others are disposed symmetrically one on each side thereof.

The upper end of the supporting bar 2 is preferably provided with a spur 2 to prevent slipping of the scaffolding. The base 1 is provided with a series of transverse diagonally extending openings 1 near its lower end and with a single similar opening 1 near its upper end. l Vhen the device is to be used upon a roof the tenon 6 of the strut is inserted in one of the lower openings l the particular one selected being determined by the pitch of the roof on which the bracket is used. When it is desired to support the bar 2 at right angles to the base 1 for use on the vertical wall of a building as shown in Fig. 2, the tenon of the strut is inserted in the opening 1 In using my improved bracket upon a roof it is supported by means of nails 10 driven into the sheathing or shingles in such a manner as to engage the three notches 9, as clearly shown in Fig. 4. The next row of shingles may then be placed so as to overlap the plate 7, as indicated at 11 in Fig. 1. 1V hen it is desired to disengage the bracket it may be swung first to one side and then to the other as illustrated in Fig. 5, thus causing the notches 9 to move away from the respective nails and permitting the heads of such nails to slip through the opening 8 as the base 1 is given a slight twisting movement. After being disengaged from the nails, the plate 7 may he slipped out from underneath the shingle 11 as will be obvious.

It will thus be seen that I have provided a strong and simple bracket which may be readily adjusted to roofs of different pitches and also to a vertical wall, and it is thought that the marked advantages of my construction will be readily appreciated by those familiar with such matters.

What I claim is Means for attaching a roofing bracket to a building, comprising a relatively thin flat plate adapted to be secured to the bracket, so as to project beyond the same, said plate having an irregular closed curved opening therethrough, and a pair of notches extending from the upper edge of such opening into said plate, said notches being symmetrically disposed on each side of the center of said opening, and adapted to engage nails driven into the building, each notch lying ont-he arc of a circle of which the end of i the other notch 15 the center, whereby elther swinging the plate about the other nail.

in presence of tWo Witnesses.
