METALLIC ROOFING.

SPECIFICATION forming part of Letters Patent No. 499,024, dated June 6, 1893.

Application filed Februarylti, 1893. Serial No. 462,874. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM R. KINNEAR, a citizen of the United States, residing at Go lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Metallic Roofing; and I do hereby 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.

The object of my invention is to provide inexpensive and durable roofing plates, which may be easily and quickly put together to form a roof or other surface covering, and which shall be free from exposed joints and nails, practically water-tight, and not liable to damage by wind or water.

My invention is embodied in a roofing plate or shingle having a bead or molding formed on its edge, made with a transverse rib or crimp for the purpose of strengthening the molding or bead, and teats for constituting a locking connection with adjacent and similarly formed plates of the roof.

In the accompanying drawings, Figure 1 represents in perspective view a roofing plate or shingle containing my improvements. Fig. 2 is an edge view showing how the plates are fitted together and fastened on the roof. Fig. 3 is a perspective view of a portion of a roof conveying an idea of the general appearance thereof when constructed of my plates; and Figs. 4 and 5 illustrate modifications of the improvements. 7

The plates or shingles will usually be stamped or pressed in dies outof sheet metal; and 1 designates the body of a plate, which may be ornamented if desired, but which is preferably plain so as to permit the free flow of Water therefrom. The edges 2 of the plate are bent to form a molding or bead of any desired cross section that will match and fit neatly on the adjoining plate to form a standing seam. Extending transversely to the direction of the molding or bead is stamped a short bead or rib 3 that serves to strengthen said molding and prevent its lateral distortion either in handling or when subjected to the action of violent wind. The transverse strengthening bead 3 preferably extends a short distance into the body or plain part of the plate where its upper side may be curved downward, as shown at 5, so as to shed water. This construction prevents the detention of any water in the corner formed by the head on the plate, and hence augments the durability of the shingle.

9 designates small knobs or teats that are struck up in the sides of the molding which when the shingles are placed together hook into each other and prevent accidental separation in a direction transverse-to the plane of the shingles. The lower edge of each plate is preferably folded, as shown, so as to form a groove 6 and anailingflange 7. The groove 6 receives and retains the upper edge of the next shingle or plate below, and water passes freely from one plate to the other without leaking through to the wood-work. The beaded or molding edge of the plate, which is intended to receive by superposition the bead or molding of the adjoining plate may, if desired, have the vertical standing part 8 to rest upon the frame of the roof to afford a firm support for any direct external pressure on the seam.

Beside the advantages hereinbefore referred to, a roof or other covering constructed of plates of shingles made with my improvements is not seriously affected by expansion or contraction due to variation of temperature, because the plates or shingles are notso rigidly connected but that they may expand sufficiently either laterally or longitudinally without warping or drawing, becoming loose at their fastening, or destroying the integrity of the covering.

Although my improvements are intended more especially for use on roofs, they are applicable and useful on the sides of buildings and other structures, the surface of which it is desired to protect.

In Figs. 4 and 5 of the drawings, which show modifications of my improvements, the transverse strengthening ribs or beads are shown as not extending through the entire cross section of the molding. The character 10 indicates a rib or bead extending partly on the molding and partly on the body of the plate; and the character 11 indicates a short transverse strengthening and locking head or rib on the upper side of the molding. The

teats or knobs in these embodiments of my improvements correspond in form and function to those already described.

What I claim, and desire to secure by Letters Patent, is

1. A roofing plate constructed at one edge with a molding having a transverse strengthening rib or bead and constructed at the opposite edge with a similarly formed molding and rib adapted to engage a molding and rib like that on the first-mentioned edge,substantially as and for the purpose described.

2. A roofing plate constructed at one edge with a molding having teats extending substantially parallel with the body of the plate and constructed at the opposite edge with a similarly formed molding and teats adapted to engage a molding and teats like that on the first-mentioned edge, substantially as and for the purpose described.

3. A roofing plate constructed on one edge with a molding havinga transverse strengthening rib and teats extending substantially parallel with the body of the plate and constructed at the opposite edge with a similarly formed molding, rib, and teats adapted to engage a molding, rib, and teats like that on the first-mentioned edge, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM R. KINNEAR.
