IMPROVEMENT IN METAL ROOFS FOR BUILDINGS.

The Schedule referredto in these Letters Patent and making part of the same.

To all whom t may concern:

Be it known that I, JOHN S. HAYWOOD, of Rochester, in the county of Olmstead and State of Minne; sota, have inventedA certaiuImprovements in Metal Roofs for Buildings, 8m., of which the following is a speciiication, referencebeiug had to the accompanying drawing.

My invention relates to met-al rooting, and consists in a novel method 'of attaching the metal sheets to the sheathing-boards by small metallic clips so jas not` to puncture the sheet-metal; and yalso in the novel construction and arrangement of a' metal cap over the adjoining upright edges of the sheets and attaching-clips.

In the drawing- Figure 1 is a top plan view, with portions broken away;

Figure 2 is a transverse vertical section of. iig.v l

Figure 3 is a side-View; and Y Figures LLand 5 are vertical cross-sections, showing two di'ereut-shaped caps, and diierent portions of adjoining sheets.

In constructing or laying this roof,the metal sheets are formed into strips, A, and have their longitudinal edges B bent up at a right or acute angle, as clearly shown in gs. 2, 4, and

' Clips or fasteners, 0, formed of the same or other suitable metal, arc i then applied for attachingthe metal sheets to the roof-sheathingl). These clips Aare made/by taking a piece 4or strip of sheet-metal,

of any suitable width, and of the requisite length, and doubling or folding it in the center, and then bending 'its doubled or folded end at right angles. with its length, and are applied, either by being first nailed tothe sheathing before the metal sheets are laid, or,

if afterthey are laid, by raisingup their edges, and then nailing, as shown in-igs. 2' and 5, and then, when thus nailed fast,`-their upper ends are bent over the upper or upright edges ofthe adjoining sheets, which are brought together, and as shown in the figures. By this construction and application of thel clips C, it will be seen thatv the sheets are iirmly 'secured, and without puncturing-them.

i Overor uponv the upright edges or ribs E of the sheets A,l with their clipsO, is placed a cap, F.

This 'c'aps made by bending a strip-of sheet-metal in the form shown at G in iig, 1; also,` in cross-section at H in iig. 2, and at I in tig. 5; that is, with its sides inclined outward, and its edges bent in under Iand upward, as shown, and is then slid or placed upon the ribs E, as shown. When in this position it will be seen that they entirely cover the joint formed by the union ot' the two sheets of metal with their fastening.

Instead of having the caps F- shaped or formed as shown at G, igzvl, and at H and I, figs. 2 and 5, re.- sp'ectii'ely, ythey may he shaped as shown at J, fig'. 1, 'and at K and L, figs. 2 and 4, respectively that is, curved, and with their edges bent in and upward, as shown. When the caps are of this forni it is obvious that the edges of the sheets or strips A may be bent apart, as shown at K and L, figs. 2 and 4.

These caps, whether with a circular'or angular top, are formed in sections, and so that their adjoining ends may slide the lower one, M, into the upper one, N,

on' the incline of the roof, as clearly shown by the dotted lines in fig. 3.

A metal roofl constructed and fastened in this way, it will be seen, requires no soldering along the line of its ribs E, and y'et is perfectly tight.4 And, as its clips 0 are only attached on one side 'of the joint, it willalso be seen that the nails withwhich they are fastened will not be liable to be loosened by the ex` pansion and contraction of the metal, as .the connec- ,tion of the metal is not rigid. In this way, I make a metal roof that is simple in construction and durable, with au unsoldered joint, so as to allow forjcontraction and expansion, and covered by anovel strip, protesting it from the weather. l

-' vHaving thus described my invention,

1. The clip `or cleats 0,'consisting of a single piece of tin, folded in the middle and having its ends hool' shaped, when applied as herein shown and described, for permanently securing the adjoining edges of a metallic roof to its sheathing, as set forth.

2. In combination with the upturnedt edges orA ribs- E of the adjoining-metal sheets forming the roof, the cap F and clips or cleats C, when constructed and arranged as herein shown and described, and for the purpose .set forth. y
