ELLswoa'rn e. WELCH, or NANKIN, omo. 1.04am to: accrue on smnm mass on m m.
To all whmn it may concern:
Be it known that I, ELLswonrn G. lawn, a citizen of the Umted States, residing at Nankin, Ashland county, Ohio, have invented certain new and useful Improvements in Lap-Joints for Roofing or Siding Sheets or the Like; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.
This invention relates to certain improvements in roofing or siding plates, sheets or squares, and relates more particularl to improvements in lap joints or such s eets and the like; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following ex lanation of the accompanying drawings ilustrating an advantageous embodiment from among other formations within the spirit and scope of my invention. An object of the invention is to provide an exceedingly simple and efiicient improved lap joint for metal roofing, covering or siding sheets or squares, wherein the edges'of the sheets are formed to overla and one of the overlap )ing edges is forme with a gutter to carry 0 moisture present between the overlapping edges by reason of condensation, ca illary or siphonic action.
he invention consists in certain novel features in construction, formation or arrangements as more fully and particularly set forth and described hereinafter.
Referring to the accompanying drawings3-Figure 1, is a perspective view of a metal sheet or square formed in accordance with my invention, the edges thereof being.
constructed to form in connection with similar sheets, V-crimp lap joints. Fig. 2, is an end view enlarged, of a V-crimp lap joint in my invention. Flg. 3, is a perspective view of a corrugated sheet or square formed in accordance with my invention. Fig. 4, is an end view enlarged of v the lap joint formed by the overlapping edges of sheets such as shown by Fig. 3.
' Metal sheets or squares, whether V-crimp orcorrugated, and whether used for roofing, siding or other covering, are secured to the backing, framework or sheathing by any suitable means and in any suitable manner, as is'well understood by those skilled in the art. The sheets are secured with their adj acent edges overlapping to form the lap joints Specification of Letters Patent.

between the sheets, and to catch and carry off water which might otherwise collect between the overlappzd edges and pass to the sheets, I form the under ge or I channel intermediate the width a eight of the is joint.
. In i s. 1 and 2, each flat sheet 1, is formed longitui inally along one edge with an outward V-crimp 2, having outwardly converging side faces meeting at the crown or apex 5 under surfaces of t I or inner edge with a longitudinal of the crimp. Along its opposite parallel edge each sheet is formed with a correspondirw crimp 3, having outwardly converging si v e or transverse faces, but with the crown l or apex of the crim depressed inwardly to form a V-gutter or c iannel 4, about midway the width of the crimp and joining the outer edges of the outwardly converging side faces of the crimp. Hence when the edges of adj acent sheets overlap, the crimped or raised edges 2, will receive, fit over and practically inclose the channeled raised or criinped edges 3, and the gutters 4, within the lap joints thus formed will catch and carry off water drawn up b capillary, siphonic or other action unclcr t e outer edges of criin )s 2, and between the engaging si e faces 0' crimps 2 and 3, thus preventing such water passing under the inner free edges of crimps 3, to the inner surfaces of the sheets.
applied to corrugated sheets or squares 5, wherein each sheet along one edge has the raised or curved outer longitudinal crimp or raised edge 6, and along the opposite edge has the corresponding longitudinal raised portion or crimp 7, having its crown longitudinally depressed to form the gutter or channel 8.
Usually the inner and outer overlap ing edges or portions of the sheets engage a ong both sides of each trough or gutter; and the outer side wall of each gutter is usually elevated or higher than the inner side wall thereof so that in the event'of a gutter being flooded, the surplus or excess water can overflow over the lower or short wall of the gutter back onto the outer surface of the roofing,
to the under surface of the roof.
What I claim as new and desire to secure by Letters Patent of the United States is: 1. A lap joint for roofing or siding sheets comprising sheets. adapted to overlap along their meeting edges, said edges being correrather than over the outer edge of the gutter In Figs. 3 and 4, I show the same invention spondmgly and longitudinally erirnped or bul ed outwardly to form the diverging side wa s, the inner bulged edge bemg lon itudlnallyidepressed to orm a gutter, sai inner edge being depressed to a greater extent down the inner diverging wal of the bulge than down the outer diverging wall thereof, whereby said gutter is formed throughout its len th with an elevated side wall, said gutter an its elevated wall extending throughout the length of said-edge and parallel therewith.
2. A lap joint for roofing or' siding sheets comprising sheets adapted to overla their meetmg edges,'sa1d edges bem o dinally crimped or bulged outwardl y ituto orm 1 the diverging side' walls, the inner bulged edge being longitudinally depressed to form a l ttere'xtendmga reater distance down the
