BRACKET FOR USE IN SHINGLING ROOFS.

SPECIFICATION forming part of Letters Patent No. 352,507, dated November 16, 1886.

Application filed March 29, 1886. Serial No. 196,895.

To all whom it may concern.-

Be it known that we, JOSEPH B. ALLEN and HERBERT W. TIOHENOR, citizens of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Brackets for Use in Shingling Roofs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,- which form a part of this specification.

The object of this invention is to facilitate the process of shingling roofs, and thereby reduce the cost thereof, and to reduce the dauger involved in such process.

The invention consists in the arrangements and combinations ofparts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the figures, Figure 1 is a front view of a portion of a roof to which the improved brackets for supporting the scaffolding are secured. Fig. 2 is a side view of the same. Fig. 3 is a detail View of a portion of abracket, and Fig. 4 illustrates a modification in the construction of the said bracket.

In said drawings, a indicates the roof, and b b brackets secured thereon by means of jaws which automatically grasp the shingles, and

bracket, 1) is a plate having at one end a thin and fiat jaw, Z), adapted to lie on the inclined roof and enter under a shingle thereof that has been securely nailed in place. Back of or below the jaw b the plate is provided with a backwardly-extending arm, bflwhich provides fulcrumal bearings 22 for a vertical lever or leg, b, which latter has a toothed foot, F, by means of which the said leg stands more firmly upon the inclined roof below the plate I). At its upper end the said leg is provided with bearings If, for a horizontal support, b", for a scaffold-board, a. At the lower end of the plate b the same is provided with bearings b for an upper jaw, b which engages the exfeet which co-operate with said jaws. Of said.

posed side of the shingle to which the bracket is secured, and thus co-operates with the under jaw, 12*, to grasp said shingle and preventsaid bracket from sliding down the incline. Said jaw b is pivoted or otherwise movably fast- 5 5 ened on said bearings-12 and extends upward approximately parallel with the under jaw to engage the shingle, as above stated. The grasping end of this jaw is preferably broadened, as shown in Fig. 3, and is provided on the under side with rows of teeth, I), which enter the wood of the shingle when the jaw is forced by the weight or pressure of the support I)". On the upper side it is or may be ribbed, as at b, to receive the grooved end of 6 5. the horizontal piece 11 and thus prevent the latter from slipping laterally therefrom. Said horizontal piece or support, fulcrumed or pivoted upon the upper end of the vertical leg, bears at itsinner end on the inclined face of the upper grasping-jaw, b and acts as a wedge to force the teeth of said jaw into the shingle.

It also tends to throw the lever-like leg at its upper end outward and at its lower end inward toward the roof, so that its tendency to slip is reduced. The outer extremity of the support b is or may be provided with a stop projection, b

By slipping the under jaw beneath theshingle and bringing the support in position to receive the board 0, the parts act automatically to grasp or clamp the shingle and hold the bracket firmly in place, and all weight brought to bear on said support I) only tends to cause the device to more closely hold to the roof. The foot has its hearings on the roof at a point in vertical line with or beyond the outer edge of the board 0, and thus overcomes any tendency toward tearing the shingle from the roof.

\tVe are aware that many changes or variations may be made in the construction of the device, one of which we have thought well to illustrate. In this case we have made the leg integral wit-h the plate I), and thus avoided the use of a lever. Other changes may be made, such as removing the jaw b and causing the support I) to act directly as such a jaw, but we prefer the construction first described, though we do not wish to be understood as limiting ourselves thereto.

IOO

Having thus described the invention, what we claim as new is- 1. A shinglers bracket combining therein jaws to grasp the shingle, one of which is pro- 5 vided with teeth b, a support resting at its inner end upon the outer of said jaws, and

adapted to force the jaws automatically into and a support, b, all arranged and combined substantially as and for-the purposes set forth. 2 4. In combination, the plate b, having jaw 1), arm 11*, and bearing b, a eo-operating jaw, b", pivoted on said bearing b", and provided with teeth b, alever-like leg, b, fulcrumed on said arm I), and a horizontally-arranged sup- 25 port, If, pivoted at the top of said leg and resting on said (so-operating jaw, all substantially as herein set forth. In testimony that we claim the foregoing we have hereunto setourjhands this 18th day of 30 March, 1886.
