Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed November 10, 1914. Serial No. 871,317.

port the staging at various positions of adj ustment vertically of the roof, as the work progresses, the clamp being disposed for detachable engagement with the shingles of the roof.

The invention has as its primary object to provide a clamp which may be readily arranged in operative position upon the roof and which may be removed with equal facility, and wherein the clamp is so constructed that injury to the shingles of the roof will be obviated.

A further object of the invention is to provide an improved clamp of this character which may be used upon any shingle roof as commonly constructed, and wherein the use of nails or other fastening devices such as would perforate the roof, is dis pensed with. And the invention has as a still further object to provide an improved clamp of this character which will be exceedingly simple in construction and thoroughly efficient in operation.

lVith these and other objects in view, my invention will be more fully described, illus trated in the accompanying drawings and then specifically pointed out in the claim which is attached to and forms a part of this application.

Figure 1 is a side elevation showing my improved clamp in position upon a roof, the portion of the roof shown being conventionally illustrated, Fig. 2 is a horizontal sectional view of the clamp showing the said clamp in engagement with the butt of a shingle, and Fig. 3 is a top plan view of the clamp.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

clamp which may be readily attached to the butt or free end of a shingle after it has been secured in proper position upon a roof, and so constructed as to support the staging. Accordingly, my improved clamp includes a relatively thin base or body portion indicated at 10 in the drawings which is preferably formed of a piece of suitable sheet metal and which may be readily inserted beneath the free end of the shingle as shown in Figs. 1 and 2 of the drawing. Adjacent one extremity, the base 10 is bent upon itself to provide an angularly disposed upstanding arm 11, the purpose of which will presently appear. It will be understood that the base 10 may be of any desired length or width and that the dimensions of the arm 11 may also be varied, as desired.

Secured to the body portion 10 intermediate its ends and substantially medially thereof is a bracket 12, which at one on tremity, may be connected with the body portion in any suitable manner as by rivets 13. Intermediate its ends, the bracket 12 is formed with an upstanding shank 14, which extends perpendicularly from the base 10 at substantially right angles thereto and which at its outer extremity, terminates in a longitudinally extending and horizontally arranged arm 15, the arm 15 being arranged substantially parallel with the base 10, and having its free end terminating in substantial alinement with the adjacent end of the base.

Arranged upon the outer free extremity of the arm 15 and adjustable thereon toward or away from the base 10 is a set screw, the screw threaded shank 16 of which engages within a correspondingly threaded bore formed in the arm, the shank 16 being provided with a suitable head 17. Swiveled upon the shank 16 at its opposite extremity is a clamping disk or foot 18.

Loosely mounted for rotative movement upon the bracket 12 is a detachable clamping plate 19. The detachable clamping plate 19 is preferably formed of sheet metal and is of a width substantially equal to that of the base 10, the said plate adjacent one extremity having an opening 20 medially formed therein to freely receive the shank 14 of the bracket by which it is normally retained in proper position. It will be observed that when the plate is in operative position the outer free end is in substantial alinement with the adjacent end of the base 10 and disposed for engagement by the foot 18 of the set screw. The opening 20 it will be observed is suificiently large to permit the plate 19 to be turned around out of the way when the base member 10 is being forced beneath the shingles of the roof.

For convenience, I have conventionally illustrated in Fig. 1 of the drawings, a portion of a roof with one of my improved clamps in position thereon in order that the application and use of. the. invention might be entirely clear. As. therein illustrated, the extremity of the base 10 opposite the arm 11 is inserted beneath the free end or butt of ,a shingle with the clamping plate 19 bearing over theend of the said shingle, and in this connection, it is to be observed that the shank 14- of the bracket 12 is disposed to limit the clamp in its inward movement upon the free end of the shingle. The set screw carried by the bracket 12 is then operated, to force the clamping plate 19 down into secure engagement with the free end of the shingle to thus firmly secure the clamp in position.

It is to be understood. that in practical use, a pair of my improved clamps is to be employed and attached to a roof in the manher just described in longitudinal spaced relation thereon, or in other words, one of the clamps may be attached to the roof adjacent one side edge thereof while another clamp may be attached adjacent the opposite side edge of the roof. When thus arranged, it will beobserved that the arms 11 will project upwardly to receive and retain a cross-piece or staging strip 21.

From the preceding description, it will be seen that the staging 21 may be readily positioned on the clamps in the manner set forth while said clamps and staging may be easily adjusted vertically upon the roof as the work progresses. It will further be seen that I provide a clamp which will not injure the shingles of the roof through being attached thereto and wherein no fastening devlces are employed such as would perforate the shingles. Owing'to the presence bracket including a base plate having its rear end bent' upwardly at right angles thereto to form a vertically disposed arm adapted to support a staging member, a'

standard secured to the base plate inspaced relation to the arm and having a horizontally disposed portion spaced from the plate and pro'videdwith a threaded opening, a.

clamping plate of substantially the same width as the base plate loosely fitted over the standard and having a relatively large opening therein to accommodate the standard and permit rotative movement of the plate with respect to said standard, a clamp screw threaded in the opening in the horizontal portion of the standard and having its upper end provided with a head, a clamping disk swiveled on the lower end of the screw and independent of and coacting with the clamping plate, to clamp a shingle between the base plate and clamping'plate when the screw is adjusted, the free end of the arm extending upwardly in a straight line above the staging member to permit the staging member to be moved vertically of the arm when placing said staging member on or removing the staging member from the base plate.

In testimony whereof I aflix my signature in presence of two witnesses.
