` INVENTOR A. L. HA RVE y Patented Feb. 3, 1931 UNITED STATES ALBERT L. HARVEY, OF LA. GRANGE, ILLINOIS CLAMP 'FOR SHINGLES Application med January's, 1928. serial no. 244,296.

means in addition to the usual nails for holding one shingle in predetermined relation with other shingles regardless of the =mate' 1o rials of which the shingles are made provided they are so made as to be flexible and subject to the influence of high winds.

Another object of my invention is to provide means for holding shingles in predetermined relation one to another without it being necessary that shingles beprovided with slots or openings for the holding means and without the shingles being of special design.

Another object of my invention is to rovide means for holding the shingles in Xed relation without the shingles being definitely spaced to match the spacing of the holes in other shingles.

Another object of my invention is to provide a relatively simple metallic clamp or grip for fastening shingles together that Will be simple and economical of construction and positive and reliable in operation.

Another object of my invention is to rovide a metallic clamp which canl be app ied with but little labor and without the roofers being required to have special training or skill.

preventing lifting of shingles on roofs already laid.

Briefly speaking, my invention consists in so bending a piece of wire of round or rectangular section that it is positioned under and between two lower adjacent shingles and having its ends extend in a curve around the bottom edge of a shingle which is located in the neXt higher course of shingles on the roof of a building. Reference may now be made to the accompanying drawing.

Figure I of which is a plan View of a roof having the shingles positioned thereon by means of clamps constructed in accordance 5 with my invention.

Figure II is a cross sectional view taken along the line II--II of Figure I.

Figures III, IV and V are views in plan, side elevation and end elevation of one of the wire clamps illustrated in Figure I of the drawing, of one form of construction. l

Figure VI is a view in end elevation ofa modified form of wire clamp constructed in accordance with my invention.

Referring particularly to Figures I and II of the drawing a plurality of shingles 1 are shown positioned upon the planks 2 that form the roof of a building. Only the roof of the building is illustrated. The shingles 1 are spaced an equal distance one from another arranged in horizontal rows or courses. These rows have been given alternately the numbers 3 and 4 to aid in describing the operation of my invention. The shingles 1 in each of the rows 3 and 4 are in staggered 70 relation to the adjacent rows above and below. y

A plurality of clamps 5 are employed to hold the shingles 1 in fixed relation one to another in a manner hereafter more fully described. One of these clamps 5 is illustrated in Figures 3 to 5, inclusive, of the drawing.

The clam 5 is made from metallic wire, preferably rom hard drawn copper or other noncorrodible metal. The clamp 5 comprises a single strand of wire which is so bent that it is provided with a straight central portion l 'Y 6, one or two end portions 7, bent at right Another object is to provide a means for angles to the central portion 6 and lying in 85 the same plane, short lateral portions 8 which lie in the same plane as the central portion 6 and are parallel thereto and two diagonally upwardly bent prongs or tips 9. The prongs'9, of the clamp 5, are pointed 90 -so` they can be driven into a shingle to hold down the lower edge.

The clamps 5 are employed to hold-the lower edge of the shingle 1 in a fixed position by first placing the clamp 5 on the bottom 95 surface of a shingle 1, as for example in lower row 3, and sliding the clamp 5 upwardly under the laterally adjacent shingles 1 which lie in the same row 3. The prongs 9 of the clamp 5 are positioned in the space 10 between these adjacent shingles 1 and are pointing outwardly from the planks 2. A shingle 1 is next placed in the row 4 vertically on line with a shingle 1, which is in a corresponding position in a lower row 4 and the shingle 1 in the row 4 illustrated in the drawings rests against the prongs 9 of the clamp 5. The ends, 9, of the clamp 5 are then driven downwardly into the shingle 1 of row 4.

By means of the prongs 9 the clamp 5 can be firmly gripped to shingle 1 which it is holding in position. The clamp 5 by holding the central lower edge of the shingle 1 near together prevents the lower edge of the shingle 1 from being lifted -by wind pressure. The prongs 9 of the clamp 5 also prevent lateral movement of the shingle 1 which it grips.

A modilied form of clamp 12 is illustrated in Figures I and VI of the drawing. The clamp 12 is also made from metallic wire having either round or rectangular cross section. The clamp 12 is made to have its major portion 13 lie in one place and so bent as to form a rectangle with one partially opened side and `having prongs 14 which are bent upwardly out of this plane. Each of the prongs 14 is so bent that the end is shaped like an inverted letter U.

The method of employing the clamps 12 is the same as the clamp 5 except that the closed side of the clamp 12 is positioned higher on the roof than the closed side of the clamp 5 for shingles in the same row or course.

A half clamp 15 illustrated in Figure I of the drawing is provided for holding shingles 1 near the edge of the roof. The clamp 15 is provided with a single prong 14 like that illustrated Jfor the clamp 12.

While I have illustrated and described my invention in its preferred form it is apparent that minor changes and modification may be made in the clamp without departing from the spirit of my invention, I desire therefore to be limited only by the scope of appended claims.

I claim:

1. A shingle clamp comprising a wire of uniform diameter throughout bent in the form of a rectangle and having its end portions bent outwardly from the plane in which the rectangle lies and each of said portions having a second bend to receive the edge of a shingle and`the extremities of said end portions being pointed and bent inwardly for driven engagement with said shingle.

2. A shingle clamp comprising a wire of uniform diameter throughout having its central looped ortion lying in one plane and its end portions bent outwardly from said plane and the extremities of said end portions bent in approximately the form of a V and adapted to receive a shingle.

3. The combination with a roof having a plurality of shingles placed in partially A. L. HARVEY.
