ROOF.

SPECIFICATION forming part of Letters Patent No. 448,529, dated March 17', 1891,

Application filed July 1, 1890- Serial No. 357,444. (No model.)

To all whom it may concern.-

Be it known that I, OLLIVER LINK, a citizen of the United States, residing at St. Charles, in the county of St. Charles and State of Missouri, have invented certain new and useful Improvements 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.

My invention relates to roof construction, the object of which is to so use sheetmetal having a tinned, zinc, or other surface that it will not be necessary to puncture it with nails or other holes in order that it may be held to its work, and thus open the body proper of such sheet metal to the action of the weather, as will be hereinafter fully described and claimed.

I11 the drawings, Figure l is a perspective view of two sections slightly separated from each other and ready to be joined. Fig. 2 shows how the locking-cap is secured in position. Fig. 3 is a sectional View of the roof completed on a line transverse with the several sections. Fig. 4 is a detail of the clamp, and Fig. 5 is a detail of the floor-support.

My improved form of roofing is especially adapted to providing a roof for railway-cars, though it is equally available in forming any kind of roofing.

In constructing my roof I use any preferred sheet metal and divide the same into pieces of suitable size, thus forming the sections A, which are of any preferred number and size, and each piece has each edge thereof bent upward at right angles to its body and then bent downward, as will be seen by reference to the drawings. \V hen the several sections are thus bent, they are placed together over the surface to be covered, sothat the upwardreaching edges of each section will rest closely against that of the adjacent section. Before thus placing the sections in conjunction with each other the clamps B are first nailed to the roof, so that the divided ends thereof will project upward and be on a line parallel with each other and on a line with the proposed junction of the sections. It will be seen by this arrangement of the clamps that the di- Vided ends thereof will project upward be tween the bent edges of the section and above the same, when one ofsaid divided ends is bent to the right, while the other is bent to the left over and thus securing the edges of the sections in position and clamping the same to the roof-support.

Referring to the drawings it will be Seen that the clamp 13 consists of a piece of sheet metal having the body I and the base 2, the latter being arranged at right angles with the former, and is adapted to be nailed to the sheeting or support for the roof. After the sections are thus secured in position the roof is completed by the addition of the lockingcap 0, which also consists of a strip of sheet metal so bent that it will be somewhat heartshaped in cross-section-that is to say, the strip of sheet metal is first bent at its middle, causing said middle to form the apex of a cone in cross-section. The edges 0 of said strip are then bent inward and upward to- Ward the middle bend, as shown in the drawmay be used to press the parts closely together, and thus tightly close the joints.

In constructing the roof of a car the several sections are bent at their middle, so as to provide a proper pitch for the roof, and in or- 'der that the usual walk may be provided for the train-men I secure to the locking-cap O on each side of the line of the proposed wall; the upwardlyreaching arms D, which are properly secured to said cap and extend upward in two parts, reaching through the mortises in the ends of the floor-support F, when one of said parts is bent to the right, while the other is bent to the left, thus securing said support firmly in position, when the parts forming the wall; may be readily nailed there to. It will be seen from the construction just described that I am able to construct a roof without the necessity of securing the sheet metal in its operative position by the use of nails. It will be readily understood that by thus dispensing with the use of nails it is not necessary to puncture the sheet metal to be used, and no broken surface is presented for the action of the weather. It will be seen that the roof can be readily removed or any defective section or part thereof can be easily replaced at small cost oi time, labor, and material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A metal roof consisting of the sections A, having their adjacent edges bent to receive the locking-cap U, the securing-clamp 13, adapted to be nailed to the roof-support, the securingarms attached to the locking-cap and arranged to secure the floor-su pport E, and the floor-support E, secured to the sections by the arms 1), thus making it possible to secure the roof to the roof-support without the use of nails, as set forth.

2. In a metal roof, the combination of the sections, the locking-cap C, engaging said sections, the securing-clamp 13, one end of which is secured to the roof-su 'iport and the other passes between the sections and arranged to secure the same by the bifurcated ends there of, the arms D, and the floor-support having mortises in either end arranged to receive the arms I), substantially as set forth.

A metal roof consistingoli' the sections A, having their adjacent edges bent to receive the locking-cap (f, the clamp B, bent at right angles near its middle, having one of its ends divided into two parts, while the other is adapted to be nailed to the roof-support, the locking-cap t, bent, as described, to snugly house the meeting edges of the sections, the arms secured to said cap and arranged to reach through the mortises in the ends of the floorsupport and thereby secure the same in position over the apex of the roof, and the floorsupport having the mortises in its ends, substantially as described, and for the purpose named.

In testimony whereof Ial'fix my signature in presence of two witnesses.
