PENNSYLVANIA, ASSIGNOR T0 ALUMINUM GOM- PANY OF AMERICA, '01? IPITTSBURGH, PENNSYLVANIA, A CORPORATION 8F PENN- SYLVANIA MEANS FOR FASTENING CORRUGATED SHEETS AND THE LIKE Application filed August 2, 1929. Serial No. 383,110.

' This invention relates to means for fastening or connecting corrugated or flat roofing sheets or siding sheets to structural elements, such as beams, purlins, girders and the like.

Prior to this invention, sheet metal roofin and siding sheets, either plain or corrugate were connected or attached to structural elements, such as purlins, rafters, beams, girders by means of two common types of fastening devices. One type consisted of a pair of headed members passing through the material to be fastened and'around the structural element to which it was to be secured, the free ends thereof being twisted together preferably beneath the lower flange of the purlin. In the other type of fastener, two headed members were also used. One of the headed members however, was provided with a bight at any desired point whereby, after the ends of the two members were twisted together as above mentioned, an looseness could be taken up by twisting the b1 ght. Both of these types, by reason of the two headed members, made it necessary to form two holes in the material to be secured. Also, due to the fact. that two headed members were used, a uniform tension in both members could not be obtained and there frequently resulted an undesirable looseness.

I have found that with a fastenin device comprising a headed member astened through a single hole in the material to be secured and cooperating with a flexible pliable material adapted to be secured to'the structural element, I can provide a fastening device which in addition to being simple and easy to apply and remove eliminates one hole secured and is substantially free from any looseness.

It is therefore an object of this invention to provide means for fastenin corrugated sheets or sidings to structural e ements comprising a single means passing through said sheets and means cooperating therewith to fasten said first named means to said structural element.

. Another object of this invention is to provide a device for fastening a sheet of material to a structural element comprising a headed member passing through said sheet cured in such a manner that it will pass around the structural element.

Other objects of this invention will appear from the following description, appended claim and accompanying drawings in which:

Figure 1 illustrates the fastening device constituting this invention, the sheet and structural element bein shown in section.

F1 ure 2 is an end view of Figure 1.

Re errmg to the drawings in which like reference numerals designate like parts, the reference numeral 1 designates corrugated sheets adapted to form a roofing or siding, disposed on purlins 2 or other structural elements. A headed member 3 extends through a hole 4 formed in the corrugated material. Theshank of the member 3 is provided with a hole 5 through which a flexible pliable member 6 is adapted to pass. The ends 7 of the member 6 are brought together and twisted beneath the lower flange of the purlin 2, as indicated at 8, forming a strap embracing the urlin and securing the headed member to t e corrugated sheet. By reason of this construction, the flexible member ad- ]usts itself during the twisting of the ends thereof so that a secure fastening, substantially devoid of any looseness, is obtained.

The flexible member 6 may be a wire formed of a solid piece of suitable material, such as annealed iron, soft drawn copper or aluminum, of such a character that it will resist considerable strain and will permit the ends thereof to be readily twisted together.

The ends 7 of the member 6 are indicated in the drawings as being brought together beneath the lower flange of the purlin. It

is to be understood that the ends 7 of the 2 Lasagna purlin as illustrated. In practice it is usual to dispose a gasket 9 between the head 10 I of the headed member 3 and the corrugated sheet 1. 5 The headed member 3 may be a rivet bolt, pin orthe like. The head thereof may be formed of any suitable design. It. may have a curved top and a flat bottom or it may be made so as to conform to the shape of the 10 corrugated material.

The fastening means above described 1s simple and efiicient. It is easy to apply and remove, if desired. The fastener is-capable of givin a direct pull on the sheet to be secured. ue to the structure and location of the cooperating arts, a fastener substantially' free from ooseness is obtained.

I claim: 7 e A device for fastening a sheet of material 00 to a structural element comprising a'headed member passing through said sheet and having a hole in the shank thereof, a wire passing through said hole and around said structural element, said wire having its ends twisted together whereby a strap is formed, said headed member being so disposed as to form the least number of bends in said wire. a In testimony whereof, I have aflixed my signature to this s ecification.

G ones A. BELDING.
