SPECIFICATION forming part of Letters Patent No. 397,381, dated February 5, 1889. Application filed SeptemherlZ, 1888. Serial No. 235,173. (No model.)

To aZZ wil/0m it 71mg/ concern:

Be it known that I, LEVI H. MoNTRoss, of the city of Toronto, in the county of York,in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Metallic Roofing or Siding, of which the following is a specification.

The object of the invention is to form the edges of the plates or shingles :in such amanner that the vertical joints shall have water channels formed below them without raising the top surface of the plates or shingles, and to form an expansion horizontal joint; and it consists, essentially, of a sheetmetal plate or shingle having one side folded to form a pocket below the level of its bottom surface, the portion of the said plate or shingle extendingbeyond the fold being depressed, and its edge upwardly curved, so as to come in contact with the bottom surface oil the adjoining plate, the edge of which slightly depressed, so as to permit it to enter the pocket, horizontal joints being formed by the upper plate or shingle overlapping the bottom plate or shingie, the two beingsecnred together and to the roof or structure by pins bent so as to clasp and secure in position the said plates or shingles, substantially as hereinafter more particularl y explained.

Figure lis a plan view showing a single plate or shingle and parts of four adjoining' plates or shingles in position. Fig. 2 is an enlarged cross-section of the vertical joint. Fig. 3 is an enlarged cross-section of a horizontal joint. Fig. 4-

an enlarged cross-seetion oi' the horizontal joint, showing the fasteningpin bent over the edge of the shingle. Fig. 5 is an enlarged detail of the fastening-pin. i

On reference to Fig. 2 it will be noticed that one side of the shingle or plate A is vfolded to form a pocket, c, below the bottom surface of the plate, and the portion ot' the plate A which projects beyond the said pocket is (lepressed, and its edge upwardly curved toward the bottom surface of the adjoining plate, the edge b of which is slightly depressed, so as to permit it to enter the pocket inthe depressml portion ot' the plate forming a water-channel, d, which channel collects and conveys away any water which may pass through the joint formed in the pocket a. It will be noticed that this joint and water-channel are formed entirely below the bottom surfaces of the plates A, and as a consequence the top surface is perfectly smooth.

B represents a pin, one point of which may be formed nail shape, sere\ shape, or perfectly plain, to suit the material of the roof or structure on which the plates or shingles are to be secured, so that the said pin may be screwed, driven in, or riveted to the structure, the pin being' bent, as indicated, so as to secure the bottomV plate or shingle to the structure. The upper plate, which overlaps the edge of the bottom plate, may be secured in position by the end of the pin B projecting through ahole near the edge of the said plate or shingle, as indicated in Fig. 3, or the end of the pin may be bent back over the edge of the upper plate, as indicated in Fig. Li. In either case both plates are securely held to the structure without interferi ng with the necessary expansion-joints between the plates.

that I claim as my invention iisl. A sheet-m etal plate orshingle having one side folded to form a pocket below the level of its bottom surface, the portion of the said plate or shingle extending beyond the fold heilig bent upwardly toward the bottom surface ofthe adjoining plate, the edge of which lits into the pocket, substantially as and for the purpose specified.

2. A sheet-metal plate or shingle having one side folded to form a pocket below the level of its bottom surface, the portion of the said pl ate or shingle extending beyon'd thefold being depressed and its edge upwardly curved towanl the bottom surface ot' the adjoining plate, the edge of which fits into the pocket, substantially as and for the purpose speciiied.

3. A series of sheet-.metal plates or shingles having a joint formed by the upper plate or sh ingle overlappin the bottom plate or shingle, the two being secured together and to the roof or structure by pinshaving one end only inserted in the strntiftnre to which the shingles are secured and the other end bent parallel with the body of the shingle, so as to clasp and secure in position the said plates or shingies, substantially as and for the purpose specified.

LLL. A series of plates or shingles having the IOC Vertical joints Connecting them formed by folding one side to form a pocket below the level of its bottom surface, the portion of the said plate o1.1 shingle extending beyond the fold being' depressed and its edge npwsndly curved toward the bottoni surface of the :uljoining plate, the edge of whieli ii's into the pocket, and the horizontal joints omned by the upper platte olf shingle overlapping the 1o bottom plato or shingle, the two being Se- Cured together and to the roof 011 struotureby pins bent so as to Clasp and secure in position the said plates or shingles, substantially as and fol' the purpose specified.
