JOHN LASLEY, OF WHITEVILLE, TENNESSEE.
SHINGLING-BRACKET Specification of Letters Patent.
Patented April 14, 1908,
Application filed June 18, 1907. Serial No. 379,644.
To all whom it may concern:
Be it known that I, J OHN LASLEY, a citizen of the United States, residing at Whiteville, in the county of Hardeman and State of Tennessee, have invented certain new and useful Improvements in Shingling-Brackets, of which the following is a specification.
My invention relates to shin ling brackets and its object is to provide a device of this class having simple and convenient means for adjusting the bracket. to change the height or angle of the plank supporting bar.
Another object of the invention is to reduce the cost heretofore encountered in manufacturing the same and this disadvantage is overcome by making each le of a separate piece of metal and joining all the legs together by a thumb screw.
An adjustable shingling bracket of this class is indis ensable where the device is to be used on (ifferent roofs as each roof as a general rule is of a different angle.
To these ends my invention is embodied in preferable form in the device hereinafter described and illustrated in the accompanying drawings.
In these drawings, Figure 1 is a side view in elevation; Fig. 2, a rear View in elevation, and Fig. 3, a top plan view.
Referring to the drawings, 1 is a leg which is adapted to be regulated to a horizontal position when the same is in use and forms a supporting bar for the workmens plank. Legs 2 made of independent pieces of metal and separate from bar 1 are provided and bent laterally at 3 to form a wide s ace between the legs at their bottom en s which engage the roof so as to hold the device rigidly in position. The legs 2 are provided. with prongs 4 to engage the roof. Leg 1 is also provided with rongs 4 and these prongs are bent downwarc ly at right angles to the upper edge of leg 1 so that the rongs will run in a direction parallel to the irection of the prongs of legs 2. This permits of the device being removed. from the roof only by raising it vertically. The weight of the workmen and their tools on the board or plank will keep'the prongs in piercing engagement with the roof. This prevents the bracket from creeping or otherwise moving and makes it safer for the workmen.
Referring to the adjustable feature of the device, the leg 1 is provided with an aperture 5 and each of legs 2 is provided with a series of apertures 6. A thumb screw 7 is adapted to pass through the corresponding apertures in the legs to clamp them together. A thumb screw is generally provided because it can be easily operatedby hand and enables a wrench and screw-driver to be dispensed with, but any other suitable and convenient connecting means may be employed.
At the end of the leg 1 nearest the thumb screw, is a head 9 which abuts against the outer edges of the legs 2 and serves as a stop to prevent movement of the legs around the screw and thereby holds said legs securely in place. To adjust the device to suit a roof of any angle, it is merely necessary to remove the thumb screw and either raise or lower the leg 1 as the case may be by engaging the screw with any one of the desired apertures, and then screw the le s together again. In working position the Tegs 2 stand substantially vertical and the leg 1 is substantially at right angles thereto and horizontal with respect to the roof so that the board or plank can be safely supported thereon.
It is clear that various changes in the d etails of the construction of the device may be made without departing from the principle of my invention.
Having thus described my invention, what I claim is:
1. A shingling bracket having a horizontal pronged-leg and two separate upright legs extending from the horizontal leg, each of said upright legs being bent outwardly so as to space each leg from the other legs at the base, and adjustable means to secure the upright legs to the horizontal leg, and a head on the horizontal leg which serves as a stop to limit the movement of the other legs, substantially as described. 1
2. A shingling bracket having three adjustable legs, one of said legs adapted to be placed in a horizontal position on the roof to receive a board or plank, said other legs provided with a series of apertures and a thumb screw engaging said legs, substantially as described.
3. A shingling bracket having a horizontal adjustable leg across which-a board or plank is ada ted to be placed and two vertical adjustab e legs provided with apertures, said horizontal leg also provided with an aperture, means to connect said le s together, said horizontal leg having a hea bearing against the outer edges of the vertical legs to limit in the movement of the horizontal leg, substantially as described.
In testimony whereof I afiix my signature, in presence of two witnesses.
