WILLIAM H. WOERHEIDE, OF NEW YORK, N. Y.

FASTENING DEV ICE FOR ROOFING.

Application filed November 20, 1916.

To (1.66 w fiom it may concern Be it known that I, iiihhikti ll. Wounnmnn, a citizen of the United Stateaand a resident of the city, county, and State ot New York, have invented certain new and use t'ul Improvements in Fastening Devices for Roofing, of which the iollmving is a specification.

lily invention relates to fastening devices for securing sheets oi prepared rooting in place by nailing, or otherwise fastening the devices onto the laps, butt-joints and dashings of roofing sheets.

My invention also relates to blanks from which the fastening devices are made.

()ne object of the invention is to secure a device for the above purpose from lightweight material and to construct the same so that it will have the necessary strength and rigidity to eliect a continuous and uniformly firm binding pressure over its entire length.

Another object of the invention is to eliminate substantially all waste in connection with the cutting of the blanks from which the article is made from a sheet of metal.

Other objects and results, as well one way of accomplishingthe above specified objects, will be apparent from a reading of the following specification, taken in connection with the accompanying drawings, in which Figure 1 shows a number of blanks in the position they are in when they are first stamped from the sheet;

Fig. 2 shows a top plan view of a portion of a strip;

Fig. 3 shows a bottom plan view oi the same;

Fig. 4 shows a side elevation of the device;

Fig. 5 shows an enlarged sectional view on line 5-5 of Fig. 2; and Fig. 6 shows a section of the device when applied to the roofing.

By reference to Fig. 1, it will be noted that the device consists of a strip of metal 1 of suitable length being provided with suitable openings 2 for fastening devices. These openings are provided in raised portions or domes 3 produced by drawing of the metal into the shape shown. The strip between the nailing points is provided with flanges or extensions l, of a general even contour so that the outer edge of the blank forms substantially a sine curve, the blank Epeciflcation of Letters Patent.

Patented I iov. 2, 1921).

Serial No. 132,308.

being narrowest at the nailing points, as shown in Fig. 1.

AS will be clear from an inspection of 1 1g. 1, the area oi the metal added to iliorm the wlde portionr-i substantially equals the area ot a space defined by the edges of the dev1ce and straight lines touching the wide points on each side of the blankthat is to say, if a line 5, is drawn tangent to the edge of the blank at its widest points 6, and another line 7 is drawn tangent to the edge of the blank at its narrowest points 8, the metal cut oil the blank by the straight line 8, in area, would equal the empty space b tween the straight line 7, and the edge of the blank. it will be noted, also, that the sides of the blank describe substantially sine curves which are 180 out of phase, and that the amplitude of these curves is equal to approximately one-fourth 01' the total increase in width of the blank at its wide portions over the narrow portions. It is this con struction which permits the cutting of the blanks from a sheet of metal without substantial waste.

It will be seen from Fig. 1 that the blanks for each device are of such a shape that when arranged, as shown in Fig. 1, the edges of the blanks are contiguous throughout. The only waste involved in the whole operation will be that of a portion approximately one-half of the distance between two mailing points in every second row of blanks. This will be obvious from the drawing, Fig. 1.

The flanges 1 between the nailing points 2 are bent under the main portion of the strip so that when the strip is placed upon the prepared roofing which it is to hold in place, the first point which will come in contact with the roofing is at a point 10 midway between the nailing points. The flanges gradually decrease to Zero at or near the nailing points. In other words, the all-over thickness of the device between each two nailing points is greatest at a point 10 approximately one-half between said nailing points, as shown in Fig. 4. It will be noted that the flanges are turned under and in, as clearly shown in Fig. 5, but not bent back into touch with the main portion.

The device has a slight upward curvature between nailing oints, when it is in position, as shown in *ig. 6. WVhen the device is secured by driving nails in the nailing points the under-and-inturned flanges 4 will V in be embedded in the roofing so that the main body portion will be in contact with the roofing throughout the entire length of the device. It may happen in some cases, though not necessarily, that theseflanges at will, when the device is fastened in position, be bent a little farther inward by reason of the pressure of the fastening means and by reason of the peculiar way in which the flanges are fulcrumed onto the main body portion.

The flanges by reason of their construction distribute uniformly the binding pressure from nailing point to nailing point. The fact that the flanges gradually decrease to zero at a short distance from the nailing points, thus leaving a substantially flat strip in the immediate vicinity of the nailing points, renders the strip flexible at the nailing points, so that a number of the short sections connected by these flexible portions can be used, notwithstanding the fact that there may be a certain amount of curvature in the roof to be covered and even permitting the use of a number of the units on strips where it is desired to carry the roofing around corners or other sharp turns or bends.

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

' 1. A device of the character described comprising a body portion having a plurality of nailing points raised from a portion of the body which is flexible, side extensions between said nailing points gradually increasg in effective thickness from each nailing polnt to a POIIIt'SIIbStELHUELlly between two nailing points.

2. A device of the character described comprising a long substantially flat body portion with nailing points raised from a portion of the body which is flexible and a flexible flange on each side ofthe body and between the nailing points, said device being relatively non-flexible except at or near the nailing points.

3. A device of the character described comprising a long flat strip with flat parts and inturned flanges alternately, said flat parts having raised nailing points thereon and said inturned flanges being flexible and effectively thickest at a point substantially midway between the nailing points.

4:. A device of the character described comprising a long flat strip of light sheet metal, raised nailing points at intervals thereon, flanges between the nailing points, said flanges being formed by turning a portion of said strip under and inward.

5. A device of the character described comprising a long flat strip of light sheet metal, raised nailing points at intervals thereon, flanges between the nailing points, said flanges being formed by turning a portion of said strip under and inward and leaving said inturned portions highest at a point substantially midway between the nailing points;

6. A device of the character described comprising a long substantially flat body portion with nailing points raised thereon at intervals, and a flexible flange on each side of said body portion, said flanges being bent toward each other on the side of the body portion opposite the raised nailing points.

7. A strip of sheet metal gradually increasing'and decreasing in width at regular intervals to form a fastening device for prepared roofing, said fastening device when completed having nailing points at the narrow points of the strip and a gradually increasing and decreasing effective thickness therebetween, said thickness corresponding proportionately to the original width of said strip.

In testimony whereof, I have signed my name to this specification. v
