Improvements in Metallic Facing-plates for Buildings and other
purposes.
I, LONGLEY LEWIS SAGENDORPH, of Philadelphia (cor. Hamilton and 23rd Streets)
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 construct a metallic plate as that a number of
said plates may be readily and quickly joined together to produce a neat and durable
facing for buildings, as will more fully hereinafter appear.
In the accompanying drawings :-
Figure 1, is a plan view of a number of my improved facing-plates locked
together, the dotted lines indicating the position of the flange and tongues on the
underlying plates.
Figure 2, is a cross-section,, on an enlarged scale, taken through that portion
when the tongue of one plate projects through and beneath the adjacent plate.
Figure 3, is a plan view of a number of plates arranged to describe a circle or
arch, showing their application as a finishing for windows or doors.
Figure 4, is a perspective view, on an enlarged scale, of one of the plates shown
in Fig. 1.
Each facing-plate A, is stamped in such a manner as to form the off-set or ledge a
along one or more of its sides or ends, said ledge terminating in an outer flange a¹
at one side of the plate when designed to be applied as shown in Fig. 3, and at one
side and one end when designed to be applied as shown in Fig. 1. The devices
shown in Figs. 1 and 3 are practically the same,—that is, the means employed for
connecting the longitudinal sides of adjacent plates are the same. In Fig. 3, the
end tongues a (shown in Fig. 1) are dispensed with, not being necessary when
forming an arch.
The off-set or ledge a is formed by rounding down or compressing the outer edge
metal below a plane with the outer face of the plate, the outer flange a¹ being on
a plane differing from said outer face, as shown in Figs. 2 and 4.
When desired to connect a number of plates as shown in Fig. 1, to represent
brick-work, the off-set a and flange a¹ are present at one side and one end of each
plate, the opposite side and end of said plate being provided with one or more
tongues a², which latter are adapted to enter the elongated openings a³ formed in
the off-set or ledge a of the adjacent plate. When desired to apply the plates as
shown in Fig. 3, the end tongues and flanges may be dispensed with.
The side of the plate on which the tongues are formed is also provided with the
ledge a, so that, when two plates are connected in the manner shown and described,
there will be formed a groove between the adjacent ledges, said groove being semi-
circular in cross-section as more clearly shown in Fig. 2, said ledges simulating the
rounded edges of brick or stone.
When applied as shown in Fig. 1, the lower row of plates are nailed to the
sheeting, and each succeeding row of plates are secured to the adjacent lower row of
plates by means of the tongues a² projecting through the openings a³ in said adjacent
plate, after which the flange a¹ is nailed to the sheeting, each succeeding row of
plates being secured and locked in place in the manner just described.
When designed to describe a partial circle as shown in Fig. 3, it is necessary
that one or more of the plates should be wider at top than at bottom, in order to
properly form the arch.
The advantages of my improved facing-plate are apparent, as the same can be

page_text: readily and cheaply manufactured and secured to place on the building, rendering
the latter practically fire-proof on. its exterior. The plates when put to place
present the appearance of brick-work; and, being preferably of a size corresponding
with ordinary clay brick, the surface of each plate is not sufficient to
admit of any perceptible. expansion or contraction: furthermore,. the tongue
connection would provide for any degree of expansion or contraction should such
provision become necessary. By forming one or more of the plates wider at one
end than at the other, a symmetrical metallic arch can be formed over windows and
doors, a feature not heretofore attained.
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 plate having at one side an off-set or ledge a terminating in a
flange a differing in a longitudinal plane from the face of the plate, said ledge
having an opening a³ therein, the opposite side of said plate having a tongue a³, for
the purposes specified.
(2) As a new article of manufacture, a metallic facing plate wider at one end
than at the opposing end, to form an arch.
(3) A metallic facing-plate having at one side and end the ledge a and flange a³,
the opposing side and end of said plate having the ledge a and tongues a³, the
ledge on the flange-side of the plate having the openings a³ therein, for the purposes
set forth.
(4) A metallic facing-plate wider at one end than at the
of said plate having a flange a¹ and ledge a, the lati
therein, the opposite side of said plate having a ledge a
purposes specified.
