STORM-TYPE SHINGLE CLAMP.

Application filed October 20, 1925. Serial No. 63,700.

To all whom it may concern.

Be it known that I, J osnrn C.BARLEY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have 'invented new and useful Improvements in Storm-Type Shingle Clamps, of which the following is a"specification. v I

This invention relates to shingle clamps for roofing shingles of that particular kind which are made by combining a congealing material with a fibrous or mineral material.

The object of this invention is to provide a shingle clamp which will embed itself into the shingle in such a manner that it will not slip off, and in this manner obviate the use of nails or other form of fasteners which require the particular attention of-the inc-- chanic for adaptation. Another object is to provide a snow catcher in a shingle clamp having the above characteristics.

Other objects will beapparent and this invention will be more fully understood from the following description, taken in connection with the accompanying drawing, forming a part hereof, and in which similar numerals refer to similarparts throughout the several views.

Fig. l-represents an elevation of one form of my shingle clamp.

Fig. 2 is a lan View of Fig. 1. I

Fig. 3 represents a group of shingles arranged in the usual manner and one form of my shingle clamp, that shown in-F ig. 1, attached thereto. 7

Fig. 4 is a sectional view of Fig. 3 taken on line 4-4, the same being somewhat enlar'g'ed, the shingles being shown in sectional view, and the clamp in full elevation.

Fig. 5 represents an elevation of a modified form of my shingle clamp.

With reference to the drawing :-The clamp as shown is formed of wire having a return bend at 6, theends 7 thereof extending downward and are bent at right angle at the points 8 in opposite directions to form the horizontal sections 9; these horizontal sections 9 are also bent at right angle at the point 10 to form the vertical sections 11; and further, these vertical sections 11 are bent at right angle at the point 12 to form the claw ends and snow catchers 14. These claw ends or snow catchers as here shown comprise merely a wire loop 15; however it will be apparent to those 5 illed in the art that these loops 15 might be modified, for

instance, to better suit manufacturin con-' ditions, without sacrificing any of t e inventive features herein disclosed. However to fulfill the objects of this invention, it is essential that claws of some character are provided at 16, and that obstructions of an effective nature for holding the snow are provided at 18. I prefer to provide. a claw 19-also, at the return bend 6 of such character which will readily embed itself in the under side of the shingle.

The manner in which this clam grips the shingles is well represented in *i'g. 4; 20 and 21 being the two shingles which are clamped and thereby held against separation; and 23 represents the shank end of the shingle 24, of Fig. 3. Normally. the clamp tends to assume a straight line as shown in Fig. 2, but the resiliency of the wire renders it capable of being sprung over the edges of two shingles, and then the various prongs 7 and 11 take the positions shown in Fig. 4.

Although the claws 16 and 19 as represented in the drawing are slightly different, in that the claw 19 is shown to be sharp, while the claw 16 has a more rounded end, nevertheless they are the same so far as their manners of gripping the shingles are concerned. Obviously in either case each claw must be sufficiently sharp so that it will embed itself in the shingle material, throu h the normal pressure efi'ected by the resiliency of the wire in endeavoring to assume its normal position as shown most clearly in Fig. 2. i

It should be understood that this clamp is primarily designed to be used in connection with shingles of the soft congealing character, that is to say, shingles which will become soft from the heat of the sun. With reference to Fig. 4, the surface of shingle 20 Where the claw 16 is located is exposed directly to the suns rays, while the surface of shingle 21 where the claw 19 is located is not so exposed, therefore the claw 16 need not, or should not be as sharp as the claw 19. Of course after a certain time the shingles usually get soft enough from the heat of the sun so that the prongs 11 and 7 will also embed at least partially in the shin le material. This condition is most desira le but not essential, but at any rate the clamp must be sufliciently yielding so that the until it can readily he slipped in place. The

prongs are then released to snap against the "shingle surfaces; It may then require some time for the claws to embed in the shingle "material, this depends upon the softness of the shingle material, or in other words its temperature.

After the clamp is sprung on the shingles, the normal reaction of the wire tendin to move the prongs 7 and 11 in the directions indicated by the arrows 25 and 26, respectively, cause the claws 16 and 19 to embed in the shingles as shown. These claws prevent the clamp from slipping oil in the direction indicated by arrow 27, even against the effect of any-snow whichmight tend to slide off the roof in this direction; the loops 15 of course-forms an obstruction to prevent the snow from sliding.

- The modified formsliown in Fig. 5, is substantially'the same kind of clamp as that shown inFig. 1; the various portions thereof which are substantially the same are indicated by like numerals. The shingles are sometimes divided at the very point where this'clamp should be placed, for instance, as represented by dotted line 28; and when the prongs 7 are'close as shown in Fig. 1-, there is a possibility that they might get between the shingle units; for this reason the'form shown in Fig. 5 has some advantage.

Having thus described my invention,

what I claim and desire to secure by Letters Patent is as follows l. A shingle clamp comprising front and rear prongs, a claw on the upper end of the rear prong and suitably arranged to hook into the shingle which is being clamped, and a combination claw and snow obstructing device on the upper end of the front prong.

2. A shingle clamp comprising resilient front and rear prongs, a combination claw and snow obstructing device on the upper end of said front prong, said claw being suitably arranged to hook into the shingle through the resilient action of said prongs,-

3. A shingle clamp comprising resilient front and rear prongs, said prongs being suitably arranged to embed in the shingle material through the inherent resiliency of said prongs.

4. A shingle clamp formed of wire, comprising prongs extending downward, lateral sections extending in opposite directions at right angle to said prongs, additional prongs extending vertically from said lateral sections. and loops formed on the ends of said additional prongs and arranged to serve as an obstruction to slidable snow.

5. A shingle clamp comprising resilient front and rear prongs, a claw on the upper end of the rear prong, said claw bein suitably arranged to hook into the s in'gle through the resilient action of said prongs.

In testimony whereof I ailix my signature.
