Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"In our method of preparing the sheets, each side of the metallic plate is grooved, or turned over, thus attaching every plate to its contiguous plate, by each of its edges. There are no separate pieces employed to form clamps, straps, or ears for nailing through, this being provided for by the mode of preparing the plate itself. Before the upper edge of the plate is turned over, it is cut in to the distance of three-fourths of an inch, more or less, two cuts being made at the distance of an inch, or any other suitable distance from each other,
and when the edge of the plate is turned over, this is left, and forms a strap by which the tin may be nailed to the roof. This strap we sometimes leave close to one corner of the plate, so that when the side of the plate is turned over, the strap is in two thicknesses; in this case it is cut of greater width than is requisite when the strap is left at some distance from the groove, or turning over.
When larger sheets of metal are used, such as those of copper and iron, two, three, or more straps, may be provided on the upper edge of the plate, the spaces between them being turned over, so as to pass into the groove, or turn over, on the lower edge of the plate, or plates, next above.
What we claim as our invention, and for which we ask a patent, is the connecting the ends of the sheets by turning over, or grooving, at the same time leaving a strap, or straps, upon the sheet to nail them to the roof in the manner herein set forth, and represented in the drawing deposited in the patent office."
