FASTENING FOR CORRUGATED METAL SH EETS.

SPECIFICATION forming part of Letters Patent No. 297,862, dated April 29, 1884. 7

Application filed February 29, 1884. (No model.)

To 60% whom it may concern.-

Be it known that I, J OHN SMITH, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Fastenings for Corrugated Metal Sheets; and I hereby do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in the manufacture of corrugated metal sheets, and in securing them in place upon buildings.

It consists of using hook-shaped fastenings instead of nails, and, further, of stamping depressions in the edge of the sheets, which depressions are adapted to fit over hooks previously attached to the timbers of a building, so that said hooks shall not prevent the overlapping sheets making a snug joint with the sheet underlying it.

Figure 1 represents a plan view of two corrugated metal sheets, one overlapping the other, and having a corner cut away, each being held in place upon a piece of timber by my improved fastenings. Fig. 2 shows in perspective one hook properly fixed toa piece of sheeting or siding with one corner of a metal sheet inserted beneath the hook end thereof. Fig. 3 is an end view, showing how two sheets are joined sidewise and held in position bymeans of acurved fastening. Fig. 4 shows the end of a corrugated metal sheet having the stamped depressions for the reception of that part of the fastening beneath which the edge of the initial or lower sheet is inserted.

Referring again to the drawings, A represents a fastening, constructed preferably of wrought-iron, having one end flattened and suitable holes punched therein for attaching it to the timber of a building by means of screws or nails, and the other turned to form a short hook.

Sheets of metal are prepared by running them through a corrugating-machine having suitable dies upon the rolls that form the de in the position shown, the indentations or def pressions B fitting within the short hooked ends of the fasteners A. As before stated, these indentations are to make room for the fasteners, so that the overlapping sheet D will not be held away from the sheet E. Any number of sheets may be thus applied, and their straight edges are secured by means of hooks O, curved to fit the corrugations, and

fastened to the timbers, as before described.

They may be placed any suitable distance from each other, and in applying them, a line of sheets having been run up the building, the hooks C are placed so that the curved ends thereof fit across the outside convex edge of the sheets, and upon applying another course of sheets-the edges of such course lap over those previously laid, and are held in such position by the short hooks upon the curved end of side fastenings, C.

By the application of my improved metal sheets, leaky nail-holes and nails are entirely dispensed with, and the sheets are free to expand or contract with the varying temperatures and conditions in which it may be placed. When the. under side of the sheets become rusty or corroded, they may easily be taken off, painted, and reversed. With a common sheet roof or siding or an inside ceiling this cannot be accomplished.

The fastenings can be applied to iron rafters of buildings by means of bolts or rivets. They may also be used in fastening slate.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 7 1. A corrugated metal sheet having depressions or indentations B stamped or rolled upon one edge or side, such indentations being situated within the longitudinal concavities of the sheet, substantially as shown and described.
