EDWVIN PRESCOTT, OF ARLINGTON, MASSACHUSETTS.

ROOFING-BRACKET.

SPECIFICATION forming part of Letters Patent No.'3ll,6'76, dated February 3, 1885.

Application filed August 18, 1884.

T0 to whom it may concern.-

Be it known that I, EDWIN PRESCOTT, of Arlington, county of Middlesex, State of Massachusetts, have invented an Improvement in Roofing-Brackets, of which the following deing drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a light yet strong bracket, which, when not in use, may be compactly folded together, the legs of the bracket, when open, diverging to form a broad base or foundation.

My invention consists in a roofing-bracket composed, essentially, of a head, a pivoted rest or seat, and jointed legs, the latter being connected between their ends with the head, and all being adapted to fold together, as will be hereinafter described.

Figure 1 is a plan view representing one of my improved brackets open and secured upon a roof. Fig. 2 is a side view of Fig. 1. Fig. 3 is a side view of the bracket folded. Fig.

at is a top view of Fig. 3. Fig. 5 is a section in the line m m, Fig. 3.

The roof has shingles A, all as usual.

The head B of the bracket has, as herein shown, three open nail-receiving notches, a b c, to engage or receive nails 2 3 4:, driven into a laid row of shingles, the said nails serving to attach the head B to the roof while another row of shingles is being laid thereon, the shingles as the said row is laid overlapping the said head, as shown in dotted lines, Figs. 1 and 2.

The head B, as herein shown, is bifurcated at its lower end, and the arms so formed are provided with suitable openings to receive joints upon or a rivet inserted through the enlarged end 5 (see Fig. 1) of the rest or seatsupport C, the latter being, it will be underderstood, pivoted to turn on the head. The outerend of the seatsupportis provided with a a lug, d, having inclined faces or sides. (See Fig. 5.) In line with this lug I have pivoted upon or to the rest or seat-support, by pivots 6, two independent legs, E E, provided at their lower ends with wedge-shaped or chisel points, to easily enter and securely hold fast in the shingles. These legs are joined with the head B by means of links or rods F F, the latter being loosely connected with boththe I (No model.)

head and legs at the poi nts 7 and 8, respectively. These rods, when the rest or seat is turned on its pivotal connection with the head, operate to turn the legs E on their pivotal points on the seat, the said legs being drawn in and made to assume a position substantially parallel with the rest when the latter is elevated in Fig. 3, completely folding the bracket into most compact shape.

Referringto Fig. 1, it will be noticed that the legs E E are made to diverge from their pivotal points. This is accomplished or pro vided for by the inclined faces of the lug d, against which the said legs bear near their upper ends, and over which the said legs move, the said inclined faces being so shaped as to insure the spreading of the legs when the rest or seat is turned into position with relation to the head B, as in Figs. 1 and 2, the folding of the parts contracting or bringing the lower ends of the legs together. The point of connection 8 of the rod F with leg E is, it will be noticed, at one side of a line drawn from the point 6 to 7, (see Fig. 3,) where the said line is dotted, such connection enabling the rods to throw the legs open when the bracket, in its folded condition, is grasped by the head and the outer end of the rest or seat-support, or, in other words, when the parts are moved so as to open the folded bracket.

To disengage the head of the bracket from the nails by which it is secured in place, as described, the operator will engage the rest or seat, slightly lift the lower end of the head to remove its prongs or feet from the shingles, and the head is then turned sidewise, as in dotted lines, Fig. 1, the nail 4 serving as the pivot, the movement of the head in such direction effecting the disengagement of the side notches of the head from the nails 2 and 3, and thereafter the head, by a direct longitudinal pull, may be withdrawn from under the shingle and away from the nail 4t.

I do not desire to limit my invention for only its use as a roof-bracket.

1 claim- I 1. The head, the rest or support pivoted thereto, and the legs pivoted upon the rest or support, combined with a rod or link to connect the head and leg, to operate all substantially as described.

2. The rest provided with a lug having inclined faces, combined with the pivoted legs, to operate substantially as described.

3. In a roof-bracket, the head provided with an open slot at one side, and adapted to be swung laterally about a nail or pivot, to remove the head from the nail holding it to the roof, substantially as described. 7

4. The head, the rest pivoted thereon, provided with the lug having inclined sides, and the legs pivoted on the rest at each side the said lug, combined with the rods or links loosely connected with the said legs between 15 their ends, the ends of the said rods connected with the legs being pivoted to the head at a point below the pivotal point of the rest with the head, substantially as described.

In testimony whereofI have signed my name 20 to this specification in the presence of two subscribing witnesses.
