CLEAT.

Application filed March 29, 1915.

To 1N whom it may concern Be it known that I, PAUL W. STANSBURY, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain-new and useful Improvements in tleats, of which the following is a full, clear. and exact description, reference being had to the accompanying drawings, forming part of ,this specification.

My invention relates to cleats in use particularly for securing roofing paper in position for use. There is a considerable art on this special line, owing to the fact that in the extremely exposed position of roofing paper, and because of the function that it exercises in the protection of buildings, the providing of a holding cleat which will stand all weather conditions without giving way. inducing rot in the paper, or leaking at the nail holes, is of grave importance.

It has been found that if a cleat having a sharp edge is nailed down over sections of roofing paper, that in cold weather, when the constituent tars and oils of the paper become hard and brittle, the paper will be cracked where the sharp edges contact with it. A cleat. however. that does not have a tight joint with the paper will allow water to accumulate under the cleat resulting in leakage and an ultimate rotting of the paper. Particular methods of securing the nails in such cleats have formed the subject of much effort in the art, in order to prevent the water that may come in through the nail holes from causing a rotting of the paper. and a rotting or rusting away of the nails themselves. thereby loosening the cleat.

it is the object of my invention to provide a cleat of the special type referred to in which tight joints are provided for without the liability of cutting. and in which the cleat is simple. comparatively flat to offer little resistance to the flow of water on the roof and adapted to be readily-and permanently secured.

These objects I accomplish by that cer tain construction and arrangement of'parts to be hereinafter more specifically pointed out and claimed. wherein a slightly downturned sharp edge is given to the cleat around the outer edge. but this edge is pre vented from pressing into and cutting the Specification of Letters Patent.

paper by a tight fitting depressed ridge within the outer edge.

In the drawings, Figure 1 is a plan view of my improved cleat. Fig. 2 is a sectional perspective view of the cleat as in use.

.The cleat is formed in dies from a long narrow strip of sheet metal, preferably rounded at the ends, although it may be angular, or square, if desired. The outer edge of the strip is rolled to form a low arch 2. The surface is depressed at 3 within the arch so as to be slightly lower than the outer edge of the cleat, and raised through the central portion to form a somewhat higher arched portion 4. Holes 5, 5 are punched in this arched portion to receive the securing nails 6.

When the cleat is secured on the roofing paper 7, the edges of the paper being overlapped as shown in Fig. 2, the pressure on the paper of the depressed portions 3, 3, will form a tight joint between the cleat and the paper, and further to insure against leakage the outer edge 8 of the clea't will also be brought to bear on the paper without the harmful efiects of a sharp cutting edge. \Vater will not be able to back up under the cleat-edge. but if. it should do so, the bead will form a perfectly tight seal to prevent it doing any damage. Owing to the deeper sunk portion 3, the edge portion of the cleat will not have the opportunity to crack the roofing paper during colder weather. whereas the depressed portion be ing in a position to crack the paper will not do so, because of its curvature.

The nature of the cleat is of course a very simple one, and there may Well be modifications of the principle of its construction. It is not believed to be necessary to mention such modifications except in so far as to call attention to the fact that in the claims that follow. it is not intended that the claims be limited to specific structure, where such limitation is not made in the Wordingot the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent. is:

1. A cleat for roofing paper comprising, a sheet metal strip having a central longitudi nal arched portion. with openings for securing nails, and a depressed portion surroiuuling its outer edge slightly below the horizontal plane of the cleat and somewhat higher than the base of the depressed portion, whereby a double seal may be obtained for the cleat to prevent the entrance of water underneath the same.
