FRANK A. ADAMS, OF ILION, NEW YORK.

SHINGLING-BRAGKET.

Application filed April 20, 1916.

To all whom, it may concern:

Be it known that I, FRANK A. ADAMs, a citizen of the United States, residing at Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Shingling- Brackets, of which the following is a specification.

This invention relates to certain new and useful improvements in shingling brackets.

The primary object of the invention is the provision of a bracket adapted to be readily clutched to the laid shingles of a roof and having locking means adapted for removably supporting a scafi'olding member in operative position upon the roof.

A further object of the device is to pro Vide a bracket that is of small dimensions but exceedingly strong in its construction having toothed jaws for engaging the shingles upon a roof, the jaws being locked in their operative position by means of a scaffold supporting cam lever.

he present invention contemplates the provision of two identical brackets positioned in horizontal alinement in spaced relations upon a partially shingled roof and adapted for supporting a- 2X4 timber arranged across the said brackets and positioning the same for the accommodation of the carpenter in laying the succeeding courses of shingles thereabove.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawings forminga part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a side View of one of the brackets operatively positioned upon a partially shingled roof, the shingles and roof .board being shown in vertical section and a scaffolding member being illustrated in end elevation partially broken away mounted upon the bracket, the latter shown in dotted lines in its released position. Fig. 2 is a top plan view of the device. Fig. 3 is a top plan view of a portion of a shingled roof with two of the brackets and a scaflolding member operatively arranged thereon, the said scaifolding member being broken away, and Fig. 4: is a perspec Specification of Letters Patent.

Serial No. 92,367.

tive view of the bracket with the movable jaw thereof removed.

The present bracket being employed in connection with a shingling scaifolding, the same is herein illustrated with reference to a pitched or inclined roof 10 having a plurality of courses of superposed shingles 11 secured thereon in the usual manner, one of the brackets being illustrated in Fig. 1 of the drawing in its operative position engaging the uppermost course of shingles and being adapted to support a scaffolding member 12 whereby the shingling of the roof may be completed by applying further transverse courses of shingles above those herein illustrated.

The present bracket consists of a base or plate 13 having a toothed jaw portion it at one end thereof and inclined rearwardly projecting shingle engaging calks 34; at its other end. A movable jaw 15 is pivoted to an upstanding post 16 carried by the said plate, the said movable jaw having a toothed inner face 17 arranged in opposition to the plate jaw teeth 14. A transverse shoulder 33 is spaced rearwardly from the teeth 14, being in alinement with the forward face of the post 16, the said shoulder and face lug constituting an abutment for the shingle 11 when the device is positioned in engagement therewith. The movable jaw 15 is provided with a slot 18 fitting over the upper curved end of the post 16, the movable jaw being pivoted to the said post by means of a bolt or pin 19. A substantially rightangular operating lever 20 is pivotally mounted to a lug 21 centrally carried by the plate 13 in alinement with the aforementioned post 16. The movable jaw 15 is provided with a longitudinally inwardly extending centrally arranged notch 22 slightly wider than the slot 18 and positioned rearwardly thereof and opening at the rear end 23 of the said movable jaw, the main or upright arm portion 24- of the lever 20 being freely positioned within the notch 22 and fiatly'engaging the inclined forward end 25 of the said notch when the lever is in its inoperative forward position. Substantially triangular-shaped operating wedges 26 are carried at opposite sides of the angle portion of the lever 20 in the form of lateral projections and through which the pivot pin 27 is extended which unites the said lever with the lug 21. The base faces 28 of the wedges 26 are in flat engagement with the inner faces of the bifurcation portions 29 of the movable jaw 15 when the lever 20 is inoperatively positioned. It will thus be evident that by elevating the lever arm 2% or in other words, moving the lever upon its pivot 27 moving the arm 2 1 in a direction away from the plate 13, the outer curved ends 30 of the wedges will become engaged beneath the bifurcations 29, thus forcing the outer end 23 of the movable jaw 15 away from the plate 13 and consequently forcing the toothed portion 17 of the movable jaw toward the toothed portion 14 of the said plate and whereby a shingle 11 may be firmly clamped between the said toothed surfaces. The opposite end of the lever 20 from the arm 24 constitutes a heel portion 31 which flatly engages the plate 13 forming an abutment when the device is in its operative clamped position. The device is preferably formed of metal, while the movable jaw 15 may be slightly resilient if desired. The forward face of the lever arm 24 is provided with a spur 32 adapted to engage within a scaffolding member or timber, such as the 22rd 12 illustrated in Figs. 1 and 3 of the drawing. l/Vhen the scaffolding member or timber 12 is so arranged upon the arms 24 of two spaced brackets attached to the same courses of roof shingles, the lower corner of the timber will be in engagement with the upper faces of the movable jaws 15, thereby preventing the levers 20 from being moved to their releasing positions prior to the removal of the said timber therefrom while the calks 34 engaging the shingles 11 prevent the bracket from slipping and with the jaws 14: and 17 firmly position the structure.

The complete operation of the device will be at once apparent from this detailed description thereof, the manner of attaching the two brackets in spaced relations upon the roof shingles having been already described, as well as the arranging of the timber 12 thereupon. The carpenter upon the roof as well as the bundle of shingles to be employed in the work are supported by means of the timber 12, a strong and serviceable support for the operator being thus arranged rendering the shingling operation less hazardous as well as protecting the supply of materials used in the work.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangement of the parts may be made without departing from the spirit and scope of the invention as claimed.

WVhat I claim as new is z 1. A shingling bracket comprising a base plate having a forwardly arranged toothed portion, a post centrally carried by the said plate adjacent the toothed portion thereof,
