SPECIFICATION forming part of Letters Patent No. 674,579, dated May 21, 1901.

Application filed September 4, 1900. Serial No. 28,997. (No model.)

T0 6r/ZZ whom t may concern:

Be it known that I, WILLIAM H. GROW, a citizen of the United States, residing at Winfield, in the county ot' Cowley and State of Kansas, have invented certain new and useful Improvement-s in Roofs; 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.

This invention relates to roofs or coverings for houses and structures of every nature requiring a top closure to exclude rain, snow, sunshine, wind, dust, and the like.

The invention deals more particularly with the covering applied to the sheathing and with the seams between the strips of roofing, said seams being standing and the roof material being paper and textile.

For a full description of the invention and the merits thereof, and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the appended description and drawings hereto attached.

While the essential and characteristic featu res of the invention are necessarily susceptible of modification, still the preferred elnbodiment of the in ven tion is illustrated in the accompanying drawings, in which- Figure l is a perspective View of a portion of a roof embodying the invent-ion. a cross-section. Fig. 3 isa detail View of the invention applied to the valley portion of a roof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The roof,of whatever structure or architecture, comprises rafters or the like and sheathing, to which the covering is applied.

The roofing or covering consists of strips 1 of tar-paper, felt, or like cheap covering and Fig. 21smeshes thereof and the cement 3 and binds all together, besides rendering the outer textile covering Waterproof. e Sand 5 is applied to the coat 4 before it dries or hardens, thereby adding materially to the durability of the roof and increasing its qualities to resist Wear. VThe strips 1 and 2 are rolled or bolted and preferably are of like width. When either strip is jointed in its length, the adjacent end portions of the parts are lapped about a foot, and care should be taken not to have the joints of the under and the upper strips register. The seams between the strips are standing and are formed in the following manner: Ribs 6 are nailed or otherwise fastened to the sheathing and are spaced apart a distance to admit of the longitudinal edge portions of the strips extending up one side and over the crest thereof. These ribs may be Wood or metal (wood being preferred) and may have any cross-sectional outline. In the preferred form the ribs 6 are triangular. The longitudinal edge portions of adjacent strips alternately overlap upon opposite sides of the ribs, as shown, and the seam is Iinished by placing thereover a narrow strip '7 of burlap or textile cemented thereto by pitch, tar, or paint. The paper covering l is secured at intervals to the sheathing by daubs 8 of pitch, paint, or like material. This obviates puncturing the material' of the roofing and provides 'a cheap and effective securing means to prevent wind from stripping the roofing fronrthe sheathing between the ribs.

When the roofing is required to be flashed, a right-angled strip 8 is secured to the sheathing in the angle formed between the roof and the Wall 9, and the edges of the coveringstrips 1 and 2 pass thereover and .under the flashing 10.

The valley of the gable-root' has the covering-strips 1 and 2 fitted thereto, and the ends of the ribs adjacent to the valley overlap the edge portions of the valley-covering and as- IOO ed to provide a. covering of desired thickness and that the sides of the ribs may be coated with pitch or paint to cause the roof material to adhere thereto Amd prevent Wind stripping the roofing from the ribs at the seams. The edges of the strips at the standing seams may be tacked to the ribs prior to placing the covering-strips in position. The dry hydraulic cement may be retained in steep places by pitch, peint, or the like applied to the surface to be protected. At the eaves the roof material will be bent down over the drip-board in the usuel manner, and at the angles and seams the materiel Will be cut to facilitate the bending thereof.

Having thus described the invention, what is claimed as new is- In roofing, a lower covering, an upper covering, a pulverulent materialfbetween the coverings and a coating of paint or the like applied to the upper coveringand binding it, the pulverulent material and the lower covering together, substantially as described.

In testimony whereof I affix iny signature in presence of twoowitnesses.
