page_text: I, LONGLEY LEWIS SAGENDORPH, of Cincinnati, Hamilton, County State of Ohio,
United States of America, Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
The nature of my invention will be apparent from the following specification.
In the accompanying drawings:
Fig. 1, is a perspective view of the top of a sheet of metal roofing embodying my
invention.
Fig. 2, is a perspective view of the under side of the sheet shown in fig. 1.
Fig. 3, is a transverse section of the sheet shown in fig. 1.
Fig. 4, is a transverse central section of a joint formed between two sheets in the
same row.
Fig. 5, is a longitudinal section of a joint between two rows of sheets, the said
section being taken along the ridge in which the sheets of the two rows are joined,
the section being perpendicular to the plane of the sheets.
Fig. 6, is a section taken at the line X-X, fig. 5.
Fig. 7, is a diminished top view of a blank sheet as it appears preparatory to being
crimped.
My invention is applicable to sheets of metallic roofing provided with upright ridges
of any description.

page_text: .
A ridge R is formed immediately at the edge of the sheet. The ridge R, has its
free edge turned up within the ridge, forming the lip L. This lip L does not extend
the whole length of the sheet, but is cut away at the ends of the sheet, as shown in
fig. 2, and for a purpose which will be presently explained. The other side of the
sheet is bent over onto itself, forming a double layer of sheeting, into which the
ridge R, r, is impressed a short distance from the edge, leaving the lip A. extending
the entire length of the sheet. The upper ridge r, and the upper layer of the lip A,
do not extend entirely along the edge of the sheet, but are cut away at each end, like
the lip L, and as shown in figs. 1, 2 and 5. The outer layer or ridge over the
ridge R¹, does not form a complete cover to the ridge R', but falls short of reaching
the main body of the sheet.
In each end of the sheet, a series of ridges N, O, and N', O¹, is impressed. The
ridges N, N¹, extend transversely across the sheet, while the ridges O, Ò¹³, are placed
diagonally.
The preferred mode of applying this roofing, is as follows:. The sheet is first nailed
to the roof as at z. Another sheet is then placed above the first, the lower end of the
second sheet overlapping the upper end of the first sheet, as far as the upper end of
the ridge of the first sheet; the ridges N¹,0¹, of the second sheet, fitting over the
ridges N, O, of the first sheet. The second sheet is then nailed in like manner as the
first. Sheets are so laid, until one row from eave to ridge pole is completed. Then,
commencing at the bottom, the next sheet is attached by placing it end to end with
the first sheet, adjusting the parts, and pushing it on to the first sheet until it
completely overlaps it; or it may be done more simply by hooking the lip L over the
ridge r. The layer approaches close enough to the top of the sheet to prevent the
lip L from working out from under it. Each sheet, as soon as placed in position, is
nailed through the lip A, and the sheets are so laid until the roof is completely
covered. Sheets provided with this form of joint are very easily connected, and form
a joint which is absolutely impervious to water, and which also provides for expansion
and contraction. The several layers of the ridges in the sheets interleave as shown
in fig. 5.
The layer and the lip L, being cut away at the ends of the sheets, substantially as
shown in figs. 1 and 2, reduces the number of layers of metal at the junction of four
sheets to four thicknesses of metal instead of six thicknesses. By this reduction of
the number of thicknesses at the joint, the latter is rendered less clumsy, more
compact, and the sheets are more easily united. This arrangement is well shown
in fig. 5.
While the particular_conformation described is preferred, still I sometimes make
the sheets with the lip L, the ridge r, and the upper layer of the lip A, extending the
entire length of the sheet, the sheet not being cut away as in the blank form shown
in fig. 7, but being perfectly rectangular. When the sheets are made as last
described, they will nevertheless be of my invention, and be constructed according to
one of the features thereof.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be used, I declare that what I claim is:
(1) A sheet of metallic roofing having at one side a ridge with an inturned edge,
and at the other side having a ridge and a nailing lip present in a double portion of
the sheet, substantially as set forth, the edge of the sheet being bent back forming the
nailing lip, and then extending up over and around the ridge below and stopping
short of the main portion of the sheet, substantially as and for the purposes specified.
(2) A sheet of metallic roofing having the ridge R provided with the lip L, lip A
and ridge R¹ having layer r, substantially as, and for the purposes specified..
(3) A sheet. provided with the ridge R¹, the edge of the sheet beyond the ridge
being bent back, and thence around over ridge R₁, forming lip A and ridge r; and

page_text: the adjacent sheet provided with ridge R whose edge is bent inward and upward
forming lip L, the ridge R embracing the ridge R¹, r, and lip L extending under the
ridge r, substantially as, and for the purposes set forth.
(4) A sheet of metallic roofing, having the ridge R provided with the lip I, lip A,
and ridge R¹ having layer r, the said lip L, and layer r, being cut away at the ends,
substantially as, and for the purposes set forth.
(5) A sheet of metallic_roofing. provided with ridges N, O, and N¹, O¹, and having
ridge R provided with lip L, lip A and ridge R¹, having layer r, the said lip L and
layer ŕ being cut away at the ends, substantially as and for the purposes set forth.
Dated the 8th day of February 1887.
