SHlNGLE-BFIACKET.

Patented May 22, 1906.

Application filed February 10,1905. Serial No. 245,068.

To all whom it may concern.-

Be it known that we, JAMES THOMPSON and HERMAN H. SGHRADER, citizens of the United States, residing at Greeley, in the county of Weld and State of Colorado, have invented certain new and useful Improvements in Shingle-Brackets, of which the following is a specification.

Our invention pertains to shingle-brackets-i. 0., devices adapted to be attached to shingle-roofs with a view of holding timbers designed to afiord foot-rests for mechanics working on the roofs; and it contemplates the provision of a simple and inexpensive shingle-bracket of great strength in proportion to its weight and one in which all of the parts cooperate to prevent casual displacement of the bracket when the same is properly applied.

The invention will be fully understood from the following description and claim when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of the shingle-bracket constituting the present and preferred embodiment of our invention. Fig. 2 is'a side elevation of the bracket. Fig. 3 1s a longitudinal central section of the same. Fig. 4 is a front elevation of the bracket, and Fig. 5 is a transverse section taken in the plane indicated by the line 5 5 of Fig. 3.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A is the lower or body member of the bracket, which is preferably of sheet-steel. The said member has a beveled forward end a, barbs b on its upper side adjacent to said end, a transverse shoulder or offset 0 at the lower side of its forward portion, slots (1 immediately in rear of the shoulder a and at opposite sides of the longitudinal center, and a hook e at its rear end.

B is the upper member of the bracket, which is also, by preference, of sheet-steel. This member B is provided with an upturned rear end f, designed to be connected by a rivet g to the upwardly-extending portion of the hook 6 with a view of increasing the strength of said portion of the hook, and it is also provided with the upwardly-bent forward portion h, slots 01 in said portion at opposite sides of the longitudinal center, and a downturned toothed forward end 9', designed in connection with the barbs h to securely hold the bracket to one or more shingles. At the point the member B is riveted or other wise connected to the member A, and hence the forward portion of said member B is free to be pressed toward and spring away from the corresponding portion of the member A.

C is a bearingpiece, preferably of sheetsteel. This piece O comprises a transverse portion Z, disposed below the member A immediately in rear of the shoulder c and riveted or otherwise connected to the said member, and standards m, extending upwardly through the registered slots d and i of the members A and B.

D is a lever fulcrumed between and carried by the standards of the piece C. This lever comprises a head a and a handle 19, the head n being arranged to bear on the member B at i a point in advance of the center of movement of the lever when the lever is in its active position, Fig. 3, with a view of precluding casual movement or loosening of the lever, and the handle p being carried, as shown, to per mit of the ready interposition of the fingers of the mechanic between the handle and the member B, as when it is desired to swing the lever into its idle position and relieve the member B of pressure.

By reason of the transverse portion of the piece C being disposed in rear of the shoulder a of member A it will be noticed that the under side of said transverse portion and the under side of the forward portion of said member A are flush, with the result that the under side of the forward portion of the bracket is smooth and free from projections, so as to permit of the forward end of the member A being readily shoved under the lower end of a shingle. The disposition of the transverse portion of the piece O below the member A is also materially advantageous, because its places the strain due to the upward pull on the standards or when the lever D is placed in its active position directly on said member A and not on the rivet connecting the piece O to the member.

E is a longitudinally-slotted plate having a depending toothed flange r at its rear end. This plate is disposed below the rear portion of the member A and is connected to said member through the medium of a bolt 8, which passes through the slot, and a nut t. The toothed flange 0 of plate E is designed by sinking into an inclined roof to assist in holding the bracket against downward movement, and the plate is slotted, as shown and dement.

scribed, in order to render it longitudinally adjustable and adapt the bracket for use when shingles having more or less exposed surface are to be laid.

In the practical use of our novel bracket the forward end of the member A is shoved under the lower end of a shingle or the lower ends of two shingles, and the lever D is swung into the position shown in Fig. 3, when, as will be readily observed,'the shingle or shingles will be securely clamped between the forward ends of the members A and B, and the bracket will be held against downward move- In thus holding the bracket on an inclined roof or the like the forward ends of the members A and B will obviously be assisted by the toothed flange r of plate E, which toothed flange will be forced into the roof by the weight imposed on the bracket. When positioned as stated, the bracket is designed to serve in connection with another bracket to hold a timber, (not shown,) the purpose of which is to form a foot-rest and support for a mechanic working on an inclined roof. Said timber is placed in the hooks e of the brackets, and when desired nails may be driven through apertures uin the hooks and into the timber to hold the latter against casual displacement.

Because of the resiliency of the forward portion-of the member B it will be observed that when the lever D is moved into the position shown in Fig. 3 the said member portion by tending to spring upwardly will assist in holding the lever against casual upward movement. It will also be observed that when the handle of the lever is moved upwardly the forward portion of the member B will spring upwardly so as to permit of the ready introduction of the butt-end of a shingle between the forward ends of the two members A and B.

We have described the present and preferred embodiment of our invention in detail in order to imparta definite understanding of the said embodiment. We do not desire, however, to be understood as confining ourselves to the specific construction and relative arrangement of the parts as shown and described, as such changes or modifications may be made in practice as fairly fall within the scope of our invention as claimed.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is v A shingle-bracket comprising a lower member having a hook at its rear end and a transverse shoulder at its under side adjacent to its forward end and also having openings at opposite sides of its longitudinal center, an upper member, of resilient material, fixedly connected to the lower member and having an upwardly-bent rear end connected to the hook of the lower member and also having an upwardly-bent forward portion and openings at opposite sides of the longitudinal center of said forward portion, a bearing-piece having a transverse portion disposed under the lower-member and in rear of the transverse shoulder thereof and connected to said member and also having standards extending upwardly from the transverse portion and through the said openings in the lower and upper members, a lever fulcrumed between and carried by the standards and having a cam-head and a handle, and a longitudinallyadjustable pl ate connected to the under side of the rear portion of the'lower member and having depending teeth.

In testimony whereof we afiix our signatures in presence of two witnesses.
