COMPLETE SPECIFICATION.
Improvements in Metallic Facing for Buildings.
I, LONGLEY LEWIS SAGENDORPH, of Philadelphia (corner Hamilton and
23rd Streets), State of Pennsylvania, United States of America, Inventor and
Sheet Metal 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, reference being had to the accompanying
drawing
:-
The object of my invention is to so form or stamp a sheet of metal as that
the same shall be ornamental and, at the same time add stiffness to the sheet
and permit of an air-space beneath the joints of the sheet, and also beneath the
peculiar shaped groove surrounding each block or figure, as will more fully
hereinafter appear.
In the accompanying drawing:-
Figure 1, is a face view of a portion of a metallic sheet embodying my invention.
Figure 2, is a vertical section through a portion of the sheet and two of the
beaded-grooves which surround each block or figure, said section being on an
enlarged scale from that shown in Fig. 1.
Figure 3, is a perspective view of a portion of two sheets of metal embodying my
invention, taken at an angle to the face thereof, showing the preferred mode of
connecting the meeting sheets at their overlapping edge portions.
My improved facing for buildings consists of a sheet of suitable metal, stamped
as shown, with rectangular figures A, each figure being surrounded by the
beaded-grooves as shown. This groove is formed by pressing or stamping the
metal inward from the face of each block A, as shown at B, and then forcing
the metal outward between said points, forming a convex bead or corrugation C
therein the full length of said groove. Each horizontal and transverse groove is
thus formed with the central bead C, as shown, the latter at its apex being
It will be seen
almost or quite on a plane with the outer face of the blocks A.
that the sides a, of each block, are nearly or quite at right angles with its
face, the metal being preferably rounded or beveled at the intersection of said
sides a and the face of each block to prevent breaking the metal at that point.
The edge of each sheet preferably terminates with the full bead C; and, in
connecting said sheets, these beads overlap each other as shown in Fig. 3; but,
this feature might be varied without departing from my invention, the leading
feature of which consists of a convex bead between rectangular figures, as set
forth.
I am aware that it is not new to form differently arranged figures by a simple
concave corrugation, the convex face of which will rest against the boarded studding;
but, in my improved facing the acute bends B, B, rest against the boarded
studding, and afford an air-space beneath the convex bead C, to prevent any decay
of the wooden foundation at those points. An additional feature of advantage
over the simple groove or concave corrugation just mentioned is, that the sheet is
doubly strengthened or stiffened by reason of the angles B, B, at the base of
each horizontal and transverse bead C.
A sheet of metal thus formed is ornamental,-the blocks A being in imitation of
brick or stone work, and the bead C simulating the mortar line; and, when
applied to a building, the sheets are not liable to rattle (being doubly stiffened)
and may be applied direct to the studding without boarding the latter, a feature
which cannot be accomplished satisfactorily with a sheet of metal not thus
strengthened.
While my improved metallic facing is designed more especially for application

page_text: to the exterior of a building, the same can be advantageously applied to the
interior of a building to take the place of wainscotting; and, when properly
painted, will form a durable, safe and ornamental finish.
Having now particularly described and ascertained the nature of said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
--
(1.) A metallic finishing plate made up of rectangular blocks or figures A, each
of which is surrounded with a groove having therein a bead convex with the outer
face of said blocks, for the purposes set forth.
(2.) A metallic finishing plate made up of blocks A, each block being surrounded
by the vertical sides and ends a, the metal between said sides being formed into a
corrugated bead C, as set forth.
(3.) A metallic finishing plate made up of figures A, each of which is surrounded
by a beaded-groove, said groove consisting of the vertical sides a, acute angles B, B,
and convex bead C, substantially as set forth.
Dated this 19th day of February 1891.
