IMPROVEMENTS IN AND RELATING TO METALLIC LATHING
Year: 1884

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO METALLIC LATHING"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
My invention relates more especially to that class of metallic lathing in which
wire cloth is employed for receiving and holding the imposed plastering, and
consists in a novel construction and arrangement of the parts as hereinafter more
fully set forth, by which, in some respects, a more effective and desirable device of
this character is produced than is now in ordinary use.
The nature and operation of the improvements will be readily understood by all
conversant with such matters from the following explanation.
In the accompanying drawing,

Like letters of reference indicate corresponding parts in the different figures of.
the drawing.
A indicates the bean or girder, B.the hanger for supporting the furring strip,
C the furring strip, D the wire cloth. or lathing proper, and E the clamp or fastener
by which the wire cloth is attached to the furring strip.
The beam or girder A is of the ordinary construction and requires no description.

page_text: The body of the hanger B is composed of a strip of sheet metal, having its ends
bent inwardly to form the flanges m, which are adapted to embrace the flanges of
the beam.
The hanger is strengthened or reinforced by a truss i consisting of a corrugated
or curved strip of sheet metal, which is placed longitudinally along the upper side
of its body and is secured in position by flanges a on said body, the flanges being
turned inwardly to embrace the edges of the truss, as best seen in Figures 1 and 3.
Projecting laterally from either side of the body of the hanger, there is a flange d,
which is folded or bent inwardly under said body and then turned or bent upwardly
over itself to form a lug for receiving and holding the furring strip C, as best shown
in Figures 1, 2, 3 and 4.
The furring strip is also composed of sheet metal, its body being nearly triangular
in cross-section and provided with flanges or projections at the bottom, to which the
clamp for securing the wire cloth to the furring is attached.
•
In the construction of the furring strip, a sheet of metal cut to the proper length
and width is bent longitudinally on parallel lines to form the edges or corners g,
inwardly inclined sides t, t, and plain or flat top r.
The side has a flange v, turned outwardly on its lower edge, and the side t,.
which is left considerably longer or wider than the side f in making the bends at g,
is bent outwardly to form the flange w, and thence carried across the strip in
parallelism with the top r, and bent upwardly and down upon the flange v, as best
seen in Figure 5, thus forming the bottom hand a double or T-shaped flange at
the lower side of the strip.
The wire cloth D is of the ordinary texture and quality usually employed for this
purpose, but has its warp and filling wires galvanized together at the points of
intersection 1, or where they cross and recross each other, the object being to keep
them from becoming displaced, more especially at, or near, the edges of the cloth in
putting up the lathing, and also to render the cloth firmer and better adapted to
properly hold the plastering.
The galvanizing of the wires together may be accomplished by any of the
ordinary processes employed for galvanizing wire, a sufficiently heavy coating being
applied to firmly unite them and also to protect the wires from oxidization.
The clamp E is composed of sheet metal, and is provided with flanges n, which
are passed through the meshes of the cloth and caused to grasp the tange of the
furring strip C, by being bent down onto either side of the same by any suitable
implement for that purpose.
The body of the clamp is indented or grooved both longitudinally and laterally,
as shown at z in Figure 6, the grooves being designed to respectively receive a warp
and filling wire of the cloth and thus enable the clamp to be brought into closer
connection with the furring strip to prevent it from showing through the plastering.
The clamp is also galvanized, and may be made larger, if desired, the number of
flanges and grooves being increased in number in accordance with its size.
The hanger shown in Figure 2 is designed for use where the furring strip runs
at right angles to the beam; but when the strip is run in the same direction as the
beain, as occasionally required, the hanger is constructed as seen at G in Figure 7.
This hanger is also formed of sheet metal, its body being made from the blank
shown in Figure 8, which is bent transversely on the dotted lines b to form the
inclined lugs for receiving and holding the furring strip C.
The body of the hanger G is strengthened or reinforced by a corrugated or
curved truss i, which is secured in position by flanges a on said body, in
substantially the same manner as the truss, shown in Figure 2, is secured to the
body of the hanger B.
Both of the hangers B, G are galvanized, thereby protecting them from moisture,
and also more firmly securing the trusses in position. The galvanizing also firmly
unites the parts of the lugs d, k, and thereby greatly strengthens them.
I do not, however, confine myself to galvanizing either the furring, hanger,
clamp or wire cloth, although I deem it preferable to do so. Neither do I confine

page_text: myself to forming the furring C of a single sheet of metal with all of its parts
integral, as the side t may be cut of the same length as the side f and have a flange
turned on its lower edge corresponding with the flange v, and the clamp E be
attached to, or suspended by, these flanges, if desired.

When the sides t, f of the strip C are so made as to be equal in width and each
provided with a laterally projecting flange vas described, said sides may be united
at the bottom by a sheath or binding plate H, as shown in Figure 9, if desired,
thereby accomplishing substantially the same result which is attained by bending
the side t and interlocking. it with the flange v of the side f, as shown in Figure 5.
· In manufacturing the hangers B, G for the market or to keep in stock one or
both of the end flanges m and lugs d, k may be left unturned until the hangers are
required for use, if desired.
By constructing the strip C with a bottom h, or sheath H, the moisture is
prevented from readily entering the body of the strip, rendering it more durable
and also much stronger.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First. A sheet metal hanger for metallic lathing, said hanger having one or both
