SPECIFICATION forming part of Letters Patent No. 659,177, dated October 2, 1900.

Application iiled July 25, 1900. Serial No. 24.855. KNO model.)

lo all whom, it may concern:

Beit known that I, HENRY E. MooMAW, a citizen of the United States, and a resident of Salem, county of Roanoke, State of Virginia, have invented certain new and useful Improvements in Metallic Shingles, of which the following is a full, clear, and eXact specification, reference being had therein to the accompanying drawings, in which- Figure l is a plan view showing several shingles interlocked; Fig. 2, a transverse sectional View of the interlocked side edges of two adjoining shingles; Fig. 3, a similar sectional View of one edge of one shingle; and Figa a view similar to Fig. 2, showing a slight modification.

The objects of the invention are to provide a metallic shingle with a side lock which will permit the side edges of adjoining shingles to be readily intel-locked and to so construct this side lock that it forms a seal which at all times effectually prevents the entrance of water or wind between the shingles and the roof and on which the expansion and contraction of the shingles have no detrimental elfect.

Referning to the various parts by numerals, 1 designates a metallic shingle whose longitudinal side edges 2 and 3 are formed to interlock with opposite edges of adjoining shingles. Near the edges 2 the metal of the shingle is bent upward, as at 4c, and from the upper edge of this portion it is bent outward and downward and then folded under upon itself to form the longitudinal sealing-flange 5, whose under side forms a sealing-surface which inclines outward and downward. From theinne'r edge of the under side of this ange the metal is bent downward and then outward to form the bottom of the channel or gutter '7,

and at the outer edge ot this gutter the metal,

is extended upward vertically to form the outer wall 8 of the gutter, said wall forming a stop which prevents the lateral separation of the shingles during the expansion or contraction thereof. From the top of this wall or stop 8 the metal is inclined downward and outward to form the cam-surface 9, and from the lower edge of this cam the nailing-strip extends outward.

Near the edge 3 of the shingle the metal is inclined upward and outward to form the cam l1, and from the upper edge of this cam it is bent downward to form the stop 12. From the lower edge of this stop the metal is extended laterally a short distance and is then extended upward and outward to form the inclined sealing-flange 13. The sealingflanges 5 and 13 and the cam-surfaces 9 and ll all have the same degree of inclination for a purpose which will be hereinafter set forth.

To interlock the edges of adjoining'shingles, the flange 13 of one shingle is passed into the channel 7 of the adjoining shingle and then brought up under the sealing-ange 5 either by forcing it into the channel edgewise 0r by sliding it endwise therein, as may be found desirable. When these edges are interlocked, the upper surface of the sealing-flange 13 will closely engage t-he under surface of the sealing-ange 5 and the Linder surface of cam 11 will fit down closely on the inclined cam 9 and the stops 8 and 12 will be in position to engage each other and prevent the lateral separation of the shingles. As the sealing-anges are of the same degree of inclination,the joint between the shingles will be eifectually sealed against the entrance of water. The stop 8 forms a seal which prevents water, which, by reason of any defect in the sealing-danges, may get into the gutter under the wall13, from passing under the shingles. As the cams 9 and 11 are of the same degree of inclination as the sealing-flanges, they will maintain said flanges in close contact during any lateral movement due to the expansion or contraction of the shingles.

The upper ends of the sealing-flanges 13 and 5 may be higher than the top of the stop or wall 12, as shown in Fig. Il, in order that should water ll the glitter formed by the wall 12 and anges 13 and 5 it will overflow wall 8 and run back on the shingle and will not overflow iange 13.

The upper end of each shingle is provided with a suitable number of transverse ridges which prevent water from passing up over the upper ends of the shingles, and the lower edges of the shingles are bent downward in the usual way to prevent water passing up under them. The upper surface of each shingle is pressed upward to form a series of curved convex ribs which extend longitudinally of the shingle and are arranged in a U -shaped panel which is nearly equal in area to the exposed surface of the shingle. These ribs are narrow at their upper ends and widen toward their lower ends, the sides of the center rib curving outward toward the adjacent sides of the shingle and the sides of the other ribs curving outward in substantially the same direction as the adjacent side of the center rib. Narrow grooves are formed between the ribs to offset said ribs from each other, and the lower ends of the ribs are beveled off, the whole arrangement giving to the greater portion of the shingle the appearance of a scalloped shell having conveXed tapering ribs. The object of this construction is to divide the Water into numerous small streams and to so direct these streams as to secure a uniform distribution of water over the roof without in any way retarding the downward iiow of the water. As will be noted, there are for the water.

A sheet-metal shingle raised and folded l near one longitudinal edge to form the longitudinal folded sealing-flange 5, inclining downward toward the adjacent edge of the sheet, and having another raised portion between said sealing-flange and the adjacent edge ot` the sheet, this raised portion constituting a longitudinal stop-wall 8 and a longitudinal cam-surface 9, and having near its opposite edge a raised portion forming a longitudinal stop-Wall 12 and a cam portion l1 and at its extreme edge an upward and outward inclined sealing-flange 13, said sealing-Hanges and cam-surfaces all having similar angles, as and for the purpose set forth.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 20th day of July, 1900.

HENRY E. MOOMAW. Witnesses:

GEORGE A. THOMAS, OHAs. P. GUNTER.
