2 claims. (o1. 10s-33) My present invention relates generally to clips for fastening the overlaps of composition roofing, either roll roofing or loose butt shingles without exposed nails, and more particularly tox clips of the type having a doubled over portion with terminal penetrating means to be clinched through the roong overlap and against the underlying portion of the clip.

Clips of the above type are in general very effective, are simple and cheap, and may be quickly placed, but have the disadvantage that in clinching the doubled over portion through the roong overlap there is considerable danger of moving the clip sidewise unless extreme care is taken and this materially slows up the operation of placing the clips.

My object is the provision of a clipof the above type in which the foregoing disadvantage is eliminated, first by a simple, though thorough, anchorzo ing of the underlying portion of the clip so that it will be rmly braced against sidewise shifting, and second, by providing the overlying portion with clinching means which will penetrate the roong and clinch against the underlying portion without any tendency to slip sidewise.

With the above in mind, the further objects, and the resulting advantages of my invention will be better understood and more thoroughly appreciated in the course of the following detailed description, reference being had to the accompanying drawing which forms a part of this specifcation, and in which,

Figure 1 is a top plan View illustrating the practical application of my invention;

Figure 2 is a sectional View taken therethrough substantially on line 2--2 of Figure 1;

Figure 3 is a detail perspective View of the clip of my invention, and

Figure 4 is a plan view of the clip blank.

l0 The clip shown in Figure 3 is formed from a flat strip of metal lil as seen in Figure 4, by bending the same intermediate its ends to form a doubled back or outer portion I I and a somewhat longer underlying or inner portion I2.

L5 The two portions of the clip are spaced apart sufficiently 'so that the overlying edge A of composition rooi'lng, either roll roong or shingles, will be received there between, and to anchor the underlying portion I2, its free end has a single i0 prong I3 turned at right angles thereto and substantially in the form of an equilateral triangle having its base of the same width as that of the portion I2. This prong I3 is substantially longer than the thickest roofing so it may be driven 5 rmly into roof sheathing C as seen in Figure 2.

At a point spaced lengthwise of the clip with respect to the prong I3, the underlying portion l2 is provided with an opening I4 for receiving a nail l5, the spacing being such that when nail I5 is driven through the underlap B of the roong 5 and into the roof sheathing I4, it will, in cooperation with the end prong I3, rmly anchor the underlying portion l2 of the clip against sidewise movement.Y

The doubled back portion II of the clip has its 10 terminal provided with anchoring means at a reverting angle thereto, and in this instance the said means are in the form of a pair of spaced oppositely disposed penetrating prongs I6 of right angled triangular contour having their straight edges and apices in line with the side edges of the portion ll and ush with the side edges of portion I2 when the prongs I6 are in anchoring relation with respect to portion II. The prongs I6 provide a pair of .spaced anchors aligning with 20 the edges of portions I I, I2 and acting to securely couple a roong section to portion Il in overlapping relation with respect toportion I2, as well as preventing lateral shifting of portion II in opposite directions relative to portion I2 and the roofing section. The prongs I 6 result from the removal of a triangular section of material at end of the clip, and it is obvious from an inspection of the blank in Figure 4 that the clip may be stamped out in a single operation. 30

After the roofing overlap A has been placed as shown in Figure 2 between the underlying portion I2 of the clip, anchored as above described, and the doubled back portion II, the latter is hammered down flat against the overlap and in doing 35 this the terminal prongs I6 of'the doubled back portion penetrate the roofing overlap and, on account of their reverting angle, readily clinch upon contact with the underlying portion I2.

In hammering the doubled back portion down upon the roofing overlap, the fact-that the two prongs IB have oppositely angular inner or adjacent sides permits of their penetration of the overlap A in a straight line, without tendency to sidewise shifting and promotes easy, quick clinching and a smooth effective roofing job.

What I claim is:

1. A clincher roong clip comprising a body in the form of a bendable metallic strip having an end portion of equilateral triangular contour and an equi-lateral triangular cutout at its outer end portion extending lengthwise of said body, the sai-d outer end portion of said body being provided by said cutout with a pair of oppositely disposed parts of right angled triangular contour, each of said parts having its straight edge forming a continuation of a side edge of said body and its apex aligning with said side edge, and said body being formed with an opening in proximity to said end portion of equi-lateral triangular contour.

2. A clincher roofing clip comprising a body in the form of a bendable metallic strip having an end portion of equi-lateral triangular contour and an equi-lateral triangular cutout at its outer end portion extending lengthwise of said body, the said outer end portion of said body being provided by said cutout with a pair of oppositely disposed
