Witnesses JOHN B. DEMARY, OF PLATTSBURG, NEW YORK SHINGLE-BRACKET.
To all whom it may concern:
Be it known that 1, JOHN B. DEMARY, a citizen of the United States, residing at Plattsburg, in the county of Clinton and- State of New York, have invented certain new and useful Improvements in Shingle- Brackets, of which the following is a specification.
This invention relates to brackets and has particular reference to a bracket which is adapted to be applied to the shingles of roofs or the like.
An object of this invention is to provide a bracket of this nature which may be readily positioned upon the shingles of a roof and which are firmly held in such position to support a scaffolding or the like when it is necessary to erect the same.
The invention has for another purpose the provision of a bracket of this nature which comprises but few parts, is strong and durable and one which can be applied without the employment of tools for the same.
For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view of a building having two brackets embodying the herein described invention upon which a beam is supported. Fig. 2 is a transverse section of the roof of a building disclosing a bracket positioned thereon, and Fig. 3 is a perspective view of the bracket detached.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawings the numeral 10 designates a shingle which is positioned upon a roof and which is disposed in overlapped relation upon a second shingle 11. The bracket which is applied to the shingles 10 and 11 comprises a metallic strip which is provided with a beveled extremity 12 adapted for engagement beneath the shingle 10 upon the upper face of the shingle 11 and which carries a threaded bolt 13 which extends upwardly therefrom adjacent the lower edge of the shingle 10 and is adapted for engagement through an aperture formed in the overlapped end of the metallic strip. The strip extends downwardly from the beveled end 12 and forms an arm 14 intermediately of which is positioned an abutment or lug 15 which is adapted for engagement Specification of Letters Patent.

in the upper face of the shingle 11 when the arm 14 is in position. The arm 14 is curved I upwardly in a vertical position to form a standard 16 which is bent inwardly and downwardly upon itself at its upper extremity to form a flange 17 against which is adapted to be positioned a beam 18. The beam 18 is supported upon a brace 19 which is inwardly extended from the flange 17 being integrally formed therewith and which is curved upwardly at the inner extremity parallel with the arm 14 to form a clamping arm 20. The clamping arm 20 is apertured at its lower end through which the bolt 13 is secured and upon the outer face of which is impinged a winged-nut 21 which is disposed in threaded engagement upon the upper end of the bolt 13 and is adapted to draw the arms 14 and 20 into engagement with one I another. A lug 22 is positioned intermediately upon the inner face of the clamping arm 20 and is adapted for engagement in the upper face of the shingle 10 to prevent the arm 20 from sliding downwardly.
In use, two or more brackets of this construction are positioned upon the shingles 10 and 11 and serve to support the beam 18 at its opposite ends. It is readily understood from the above description that the bracket may be disengaged or positioned upon the roof quickly and easily by simply releasing the arm 20 from engagement with the upper face of the shingle 10 by loosening the winged-nut 21 upon the bolt 13.
As disclosed in the drawings, the arm lt is bent inwardly at its lower extremity to engage against the shingle 23 which is disposed beneath the shingle 11 and extended downwardly therefrom. This forms a support for the arm 14 to brace the standard 16 in rigid position and thereby prevents the vibration of the bracket when various weights are positioned on the same.
Having thus described the invention, is claimed as new is 1. A bracket as specified comprising a what metallic strip so bent as to form an arm, a
winged-nut positioned in threaded engagement upon said bolt adapted for engagement against the upper face of said clamping arm and lugs projected upon the under faces of said arms.
2. A bracket as specified comprising a metallic strip bent to form an arm for engagement upon a shingle roof, the upper extremity of said arm engaged beneath a shingle upon the roof, a standard vertically extended upon the lower end of said arm, a brace inwardly extended from the upper end of said standard, a flange formed vertically upon the upper end of said standard and a clamping arm curr ed upwardly from said 15 brace in parallel With said first arm, lugs carried by said arms for engagement with the upper faces of the shingle of the roof and a clamping bolt secured to said arms for binding the same upon the opposite sides of 20 the interposed shingle of the roof.
In testimony whereof I aflix my signature in presence of two Witnesses.
