' MANUFACTURE OF RlDGE-CAPS FOR CORRUGATED ROOFBMG.

, SPECIFICATION forming part of Letters Patent No. 317,868, dated May 12, 1885.

Application filed November 3, 1884.

To all whom it may concern."

Be it known that I, J OHN SMITH, of Kansas City, Jackson county; Missouri, have invented certain new and useful Improvements in the Manufacture of Ridge-Caps, &c., for Gorrugated Roofing, of which the following is a full, clear, and exact description.

The object of my invent-ion is to construct sheet-metal ridge-caps from an'integral sheet in. such a manner that comparatively watertight joints may-be formed between the cups and the underlying corrugated roof-sheets.

Myinvention consists, principally, as an improvement in methods of abruptly bending corrugatedmetal sheets across the corrugations thereof, substantially as and for the purposes hereinafter specified.

Reference is to be had to the accompanying drawings, forming part'ofthis specification,in which similar letters of reference indicate corresponding partsin each figure.

Figure 1 is a plan of the upper, surface of one of my improved ridgecaps. Fig. 2exhibits a slight modification in the method of bending the'samc. Fig. 3 is a half-section upon line a a, and the same upon line b b, Fig. I. Fig. 4 is a section through that portion of the sheet coming in contact with the -lmilding. Fig. 5 is a section through the apex of a corrugation. Fig. (i is a perspective view of a varied form of the ridge-cap applied to the upop the longitudinal line ff, Fig. 2.

and Fig. 7 is a sectionl igs. 8 and 9exhibit my improved corrl'lgated sheets inverted and applied to a building in the form of flashings, and Figs. 10 and 11. show the manner in which they are used in the form ofguttersand eaves.

Heretofore ridge-caps for corrugated roof ing have usually been constructed somewhat of the form shown in Fig. (i; but their overlapping edges were devoid of the corrugations a, and their plain surfaces rested upon a lining-strip of wood. This strip was provided withaplain upper surface; but the surface next the roof-sheets, in order to form a joint therewith, was corrugated laterally'along the entire length corresponding to the concavities of the said sheets.

In constructing my improved ridge-cap I roof of a building;

,provide a ready-corrugated sheet, H, of suitable dimensions, and bend it to any predetermined angle .at or near its central line across its corrugations, and in so doing form (Modeh) corrugations at the said point are practically done with and a straight line is formed in the sheet. I accomplish this byforming crimps or raised portions A upon the said bead or apex A as it is being formed. ,These are preferably formed upon a line, a a or d d, with the convex portions of the corrugations. The said raised portions (as shown in the drawings) taper outwardly from the sides of the bead A to a point, as E or B. 1

- If desired, the head A may be formed with a comparatively abrupt apcx, (indic-ated by D in Fig. 1,) and, in asimilar man nerto the raised portions, terminate at a point, 0, within the concavities of the corrugations. In Fig. 7 it will be noticed how the metal is-folded at 0 above the bead A. By heating the sheet sufficiently before the bending pro-- cess is begun I am enabledto form a ridgecap' with a' plain head, as shown in Fig. 6.

I prefer that the sheets above described be allixed to the roofs, &c., of buildings by means of the improved fastening-hooks specified in my I] nit-ed States Patent No. 297,862.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A corrugated sheet of metal for roofing purposes, having acomparativcly abrupt bend or bonds directly across its corrugations, whereby the converging edges thereof may form any desired angle with each other, substantially as specified.

2. A sheet of metal for roofing purposes,

having corrugated sides diverging 'from an apcxial bead formed integral therewith, sub-.
