Improvements in or relating to the Construction of Building Walls
and in Sheet Metal Coverings therefor.
A communication by PHILLIPPE AUGUSTE DESLAURIERS and CLARENCE DAVID
PRUDEN, both of St. Paul, in the County of Ramsey and State of Minnesota,
United States of America, Manufacturer and Machinist respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street, Manchester, both
in the County of Lancaster, and 323 High Holborn, in the County of Middlesex,
Civil Engineer, 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:-
This invention relates to improvements in the construction of building walls
and sheet metal coverings therefor.
In the accompanying drawings forming part of this Specification.
Fig. 1 is an elevation of a building front illustrating the invention.
Figs. 2 3 and 4 are details illustrating the wall structure in which sheet metal
studs, and iron sheathing and lath are employed;
Fig. 5 is a similar detail showing wooden studs ;
Fig. 6 is a modified construction in which wooden studs and lath are employed;
Figs. 7 to 21 inclusive show a modified construction in which sheet metal plates
are secured to a masonry wall;
Figs. 22 and 23 are details showing siding plates for the ornamental parts of
a front secured directly to the wooden framework, and
Figs. 24 to 30 inclusive are details showing the construction of the siding plates
and the manner of interlocking and securing the same to the structure.
This invention may be employed as a fire protection for old walls, or in the
original construction of the wall itself, by means of which it may be made slow
burning or absolutely fire proof. Figs. 2 and 3 represent such fire proof structure,
and Figs. 5 and 6 the slow burning structure, while Figs. 7 to 21 inclusive show
the sheet metal covering as applied to masonry walls either new or old.
In the drawings A represents a sheet metal stud, folded upon itself to form a
central web 2, and ribs 3, the ribs serving to stiffen the stud. The edges of the
web are preferably provided with lips 4 which may be outturned to engage and
hold the corrugated sheet metal sheathing 5 slotted to fit upon the studs.
Upon the projecting upper edges of the sheathing plates or sheets 5, may be
hooked the siding plates C, formed with a double bend or fold 7 to fit over the
edge of the sheathing, the upper edge of the plate projecting into and being held
by the fold of the plate above; (see Figs. 2 and 3).
Where the slow burning construction is employed, the corrugated sheathing may
be nailed directly to the wooden studs 8, (see Fig. 5), or crossed wooden lath 9
may be nailed to the studs, as shown in Fig. 6. In this construction the siding
plates are nailed through the lath to the studs.
Where the siding plates are secured to the masonry wall, as shown in Figs. 7
to 21 inclusive, anchors 10 are fixed in the wall. To these is secured an angle
ron framework made up either of a series of vertical bars 11 and horizontal
bars 12, or of horizontal bars alone, the siding plates themselves being locked or
therwise secured to the horizontal bars. Various modifications of this construction
nay be worked out as shown in Fig. 8, where a sheet metal angle plate 13 is
nchored in the wall B, and the siding plates attached to the outturned edge 14.
The siding plates are made in imitation of blocks of stone or brick, either with
he representation of a single block to the plate, (see Figs. 2 and 5), or with several

page_text: to the plate, (see Fig. 24), representing irregular or broken ashler. The vertical,
interlocking joints of the siding plates are provided with a conduit 15 formed by
the outturned edge and reverse. bend of the inner plate, the outer plate lying over
the conduit and extending into the fold of the other plate, (see Figs. 24, 25
and 28). Figs. 26 and 27 illustrate the manner in which the plate is cut and folded
to form interlocking edges. Fig. 28 also shows the manner in which the conduit
extends into the fold along the lower edge of the interlocking plate.
The spaces between the lath and the siding plates are filled in preferably with
concrete 16 or similar non-combustible material, to give solidity to the structure
and further protection from fire. The inner surface of the structure is covered by
concrete or mortar 17 thus forming a double wall with an included air space.
In
the ornamentation of the wall or front, the colunins, pilasters and cornice siding
plates are secured to the structure, and interlocked with each other as illustrated
in Figs. 4, 9, 21, 22 and 23.
Where the siding plates are secured to the metallic framework upon the wall
of the building, the upper edge of the siding plates is firmly secured to the angle
bar preferably by means of the tongues 18 in the plate, passed through the openings
in the angle bar and bent back of the same, or by means of the sheet metal angle
pieces 19 or 20 as shown in Figs. 11 and 12.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
1: A sheet metal siding plate having its lower edge formed with a double fold
to receive the upper edge of the plate beneath, and one of its vertical edges formed
with a double fold to receive the edge of the adjacent plate, and with a water
conduit arranged beneath the adjacent plate and projecting over the plate below.
2. In a building wall, the combination of the studs, the lath or perforate
sheathing upon the outside of said studs, and the fire proof filling between said
lath or sheathing and plates.
3. In a building wall, the combination, with the studs, of the perforated, corrugated
sheet metal secured. thereon, siding plates secured outside thereof and the non-
combustible filling between.
4. In a building wall, the combination of the metallic studs, the frame work, the
siding plates secured thereupon and a non-combustible filling or backing for said
plates.
5. A building stud formed of sheet metal folded upon itself to form a web and
radiating ribs.
