SECURING ELEMENT FOR COMPOSITIGN SHINGLES.

Application filed March 2, 1925. Serial Ito. 12359.

I '0 all whom it may c0acem.-'.

Be it known. that I, FRANK. VANnnvEN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Securing Elements for Composition Shingles, of which the following is a specification.

My invention relates to improvements in the manner of laying and securing composition shingles upon roofs, and its objects are: first,'to provide a means whereby the corners and center of the shingles, at the lower ends, may be positively insured against the danger of a heavy wind passing under them and raising them from their proper bearings upon the surface of the next preceding row of shingles; second, to provide a means whereby the sidewise expansion and contraction of the shingles will be fully provided for; third, to provide a means whereby the securing elements will be sufiiciently rigid to avert the danger of th ir being bent or becoming unreliable by re son of any strain that might be forced upon them by the action of heavy wind passing under the lower ends of. the shingles; fourth, to provide securing elements that when passed under the edges of the shingles will not raise the shingles perceptably from the roof boards, and that will not form unsightly ridges in the shingles, and, fifth, to provide securing elements for the shingles that may be properly enameled and arranged to give to the roof an artistic and ornamental finish.

I attain these objects by the construction and arrangement of parts shown in the accompanying drawing, in which Fig. 1 is a plan of the blank from which my securing elements are made. Fig. 2 is a plan of a completed securing element.- Fig. 3 is a perspective end view of said element from the upper end thereof. Fig. 4 is a plan of a part of a roof showing how the shingles are secured to the roof with my securing elements, and, Fig. 5 is an edge view of the securing element.

Similar reference characters indicate similar parts throughout the several views.

My invention consists of a sheet metal securing element of practically the form shown in Fig. 2, having the body part 1, a

clamping tongue 2 cut from one end of the body, a strengthening rib, V formed, struck upwardly in the body 1, and curved slots 4 formed in the other end of the body.

This supporting element is applied as follows: First, it is firmly secured to the roof by means of nails, or other securing elements passed through the slots 0 into the roof boards. The flap or metal over the slots 4 should be sprung upwardly suiticiently so the corners of the shingles may be readily passed into the slots, as indicated at a in Fig. 4:, and I prefer that the clamp 2 be slightly curved, as shownin Fig. 5, so that when hammered down upon the surface of the shingle it will penetrate it slightly for the purposes: first, of securing it so firmly to the shingle as to avert any possible danger of its being bent upwardly and allowing the shingle to become loose and unsupported at this point, and, second, to insure so close a connection between the surface of the shingle and the clasp as to positively prevent any possibility of Water percolating through between the clasp and the surface of the shingle. When the securing element is properly secured to the roof of the building, the clasp 2 and the metal over the corners of the shingles, at 4, should be struck a sharp blow with a hammer to properly embed them into the surface of the shingle.

In laying the shingles upon this securing element the lower edge of the shingle, 5, is passed into the slot 4 with the edge of the shingle close to the lower line of the rib 3, and the securing elements, as nails, with which the shingles are secured to the roof boards, should be set well in from the edges of the shingles, as indicated at Z), to give sufficient room at each side of these points for the free expansion and contraction of the shingles without too much space between the points I). The center of the lower edge of the next succeeding row of shingles is placed under the clasp-2 and the corners in the slots 4 so that both the centers and the corners of the shingles are held firmly in place. 5 indicates the outline of the upper ends of the shingles.

It will be readily understood that if itis desired to utilize my securing elements. to add an ornamental finish to the roof, it

menses will be, only, necessary to enamel, paint or otherwise finish the ribs 3 and the end 4- in any color or design desired.

Having thus fully described my inven tion, What 1'. claim as newin the art, is:

1. In an element for securing composition shingles to a. roof, a thin, narrow, 0hlong sheet of material laid under, and lengthwise of the adjacent edges of the shingles and having curved diagonal slots in the lower end to receive and secure the lower corners of 'adjacent shingles, and a lip formed at the upper end adapted to interlock with the center of the lower end of the next upper shingle.

2. In an element for securing the ends and edges of composition shingles, a thin,

narrow, oblong body having slots in one end to receive and hold the corners of the shingles and a; centrally formed strengthening rib formed longitudinally of the body.

3 in an elementfor securing the ends and edges of composition shingles to the roof of a building, a thin, narrow, oblong body having slots in one end for the reception of the corners of shingles, a strengthening rib centrally located in said body and extending longitudinally thereof, and n clasping lip cut into the other end of said body in the direct line of said strengthening rib, for securing the center of the lower end of each shingle,

VANDEVEN.
