Improvements in Metallic Facing Plates for Buildings.
I, LONGLEY LEWIS SAGENDORPH, corner Hamilton and 23rd Streets,
Philadelphia, State of Pennsylvania, United States of America, 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 :-
In the drawings,—
Figure 1, is a perspective view of a portion of two facing plates before being
lapped, the same being illustrative of my invention.
Figure 2, is a cross-section taken on the dotted line 2, 2, of Fig. 1, after the
plates in said latter figure have been lapped and united.
Figure 3, is a face view of a portion of two plates lapped and united in the
usual manner, said view being designed to more clearly point out the features of
novelty and utility embodied in the preceding figure.
My invention consists in forming on one end of a metallic facing plate A, the
alternating projections a, the latter being adapted to overlap the full end portion
of the adjacent plate as shown by section in Fig. 2.
My invention is more especially designed for use in connection with metallic
plates stamped or pressed to simulate brick-work, and having longitudinal and
alternating transverse beaded grooves, as shown; but, if desired, my invention may
be advantageously used in connection with facing plates of an outline configuration
differing from that herein shown.
When stamped as shown, each rectangular figure or "brick" is surrounded by
the longitudinal and alternating transverse grooves having therein the convex bead
or corrugation b.
One end of each plate is provided with the extensions a which project outward
about one-half the length of a "brick,"-each alternating "brick" being cut
away along the base of the bead b, as shown. The opposite end of each plate is
formed full or flush, as shown at left hand in Fig. 1; and, in forming the lap or
seam, the projections a on the end of one plate overlap the "half-bricks
adjacent plate, the corrugated beads on the one plate overlapping the corre-
sponding beads on the adjacent plate, and in this manner a perfect joint or seam is
effected.
"
on the
When lapped and secured together in the old manner, as shown in Fig. 3, the
rain is liable to beat in between the overlapping end portions; and, in such event,
the moisture will be retained between them and rust out the metal. Another
disadvantage consists in the fact that a perfect uniform seam cannot be effected in
the old way and the symmetry of the "bricks" is destroyed along the seam.
The aforementioned disadvantages are overcome by constructing the one end of
each plate in the manner designated, as any water that may beat in beneath one
projection a will run down on the outside of the adjacent plate at the cut-away
portion of the top plate and there be quickly evaporated. The seam thus formed
is more durable and stronger than when formed in the old method, as there is
a lap of one-half of each alternate "brick." When constructed in the manuer
illustrated in Figs. 1 and 2, the symmetry of the "bricks or rectangular figures
is retained along the seam, each projecting "half-brick" overlapping the "half-
brick" on the adjacent plate.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is―
(1) A metallic facing plate having at one end thereof the projecting portions a,
the latter being adapted to overlap the adjacent plate at one end thereof,
substantially as Bet forth.
(2) A metallic facing plate having longitudinal grooves and alternating cross-
grooves, one end of said plate being cut away along the base of said latter grooves
having the projecting portions a, substantially as specified.
(3) A metallic facing plate having longitudinal and alternating cross-grooves,
each groove having centrally therein the convex bead b, one end of said plate
having the portions cut away along the base of said beads, the latter being adapted
to overlap the corresponding beads on the adjacent plate, substantially as set
forth.
Dated this 29th day of August A.D. 1892.
