FRANK J. PIOOH, OF PROVO CITY, UTAH.

SPECIFICATION forming part of' Letters Patent No. 762,939, dated June 21, 1904.

Application filed November 14, 1903. Serial No. 181,219. (No model.)

T0 all whom t may concern:

Be it known that I, FRANK J. PIOCH, a citizen of the United States, residing at- Provo City, in the county of Utah, State of Utah, have invented certain new and useful Improvements in Scams for Metallic Roofing, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a seam for metallic roofing, and particularly to a structure embodying a gutter or trough having an interlocked cap coperating with the gutter thereof.

The invention has for an object to provide a novel and improved construction of seam for metallic roofing-plates, comprising a gutter or trough having parallel ribs at its opposite sides and an intermediate flange extending laterallyT from one thereof coperating with a cap adapted to entirely inclose the cooperating trough and having a flange to interlock with the laterally-extending flange of the trough or gutter. n f

Other and further objects and advantages of the invention will be hereinafter set forth, and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a/perspective of the plate, having at one edge a cap construction and at its opposite edge a gutter. Fig. Q is an enlarged detail of the coperating cap and gutter separated from each other, rlicHFig. 3 is a perspective of the partsassem- Like letters of reference refer to like parts in the several figures ofthe drawings.

The letter A designates a plate, preferably of metal, such as ordinarily used for roofing purposes, and of any desired configuration for use either as a shingle or roofing-plate. Upon one edge of the plate a cap B is formed and comprises an upwardly-bent portion B' at one side and a depressed portion B2 at the opposite side, while from the latter portion an inwardly-overturned interlocking flange B3 is provided and disposed parallel with the under face of the cap. plate the coperating part O may be formed and comprises parallel ribs O and O2, spaced from each other to form a gutter or trough At the opposite edge of the O3, While beyond the rib O3 the free end OL of the plate is provided, by which it may be secured to the roofing-timber in any desired manner-for instance, by nails C5. as shown. Projecting laterally from the rib C is a horizontally-disposed laterally-extending projecting fiange "l, which covers the principal portionof the gutter, leaving an opening O7 at one side for the introduction of the interlocking flange B3 of the cap member.

In the operation of the invention the parts may be assembled by sliding the gutter and cap longitudinally upon each other or the interlocking flange may be engaged and the free end of the cap member bent downward to complete the joining, which forms a standing seam having a broad upper surface not liable to injury by rough usage nor 'by Walking thereon, as the parallel ribs .in connection with the cap form a bridge over the gutter. It will also be noted that the ribs and the protecting-ange from the inclosed gutter are formed by a double thickness of the material, thus lending strength against'a vertical or lateral compression thereof. The gutter here provided is adapted to catch and convey water from the roof in the event of fiooding, so as to percolate through the seams, While under ordinary conditions the gutter is completely closed by the cap and protected thereby against the entrance of Water even in a severe or driving storm. A further important feature of the construction is the location of the interlocking flange upon the under face of the cap, whereby it is not liable to injury or bending out ofproper shape,.and therefore may be readily engaged with the protecting-flan ge of the gutter, so as to lock the parts securely against vertical separation, While the flanges of the gutter and the Walls of the cap effectually prevent any lateral movement thereof. It will be noted that the connectionv of the locking-flanges forms a double-locked seam that is storm and Water proof, While the bridging between the ribs effectually prevents injury to the seam, even under rough usage.

It will beobvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of the invention as defined by the appended claims.

TOO

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-

1. In a rooling-seam,a gutter provided with parallel ribs, a cap-plate extending over and completely inclosing both of said ribs, and means carried by the cap for connecting said cap to one oi' said ribs.

2. In a roofing-seam, agutter provided With parallel ribs, a cap-plate completely inclosing said ribs, a laterally-projecting flange extending from one of said ribs over said gutter, and an interlocking iiange carried by the under face of said cap. Y

3. In a roofing-seam, agutter provided with parallel ribs, a cap-plate completely inclosing said ribs, a laterally-projecting flange extending from one of said ribs over said gutter, and an interlocking flange upon the under face of the cap comprising a reversely-bent portion ofthe free end of the cap-plate adapted to embrace said projecting flange.

4. 1n a rooting-seam, a gutter formed from the body of a plate and comprising parallel ribs one of Which has a protecting-flange projected laterally therefrom toward the opposite rib, a cap-plate formed to embrace both of said ribs and provided upon its under face with a reversely-bent interlocking flange open at one side to permit the entrance therein of the protecting-flange.

ln testimony whereof Iaflix my signature in presence of two Witnesses.
