I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
This invention relates to metallic lathing and to a foundation therefor, the laths
of which lathing are twisted or spiral and are secured to a corrugated metallic
plate in such a manner as to afford a means for holding a plastic covering or
cement to the walls and ceilings of apartments.
My said invention consists partly in the combination with lathing, of a
corrugated metallic foundation having a series of parallel depressions or channels
each of which is bridged at suitable intervals by projecting loops that are struck
up from the body of the metallic foundation plate to form a series of supports or
fastenings for the lathis.
The invention also partly consists in a corrugated foundation plate having a
series of parallel grooves or depressions provided at intervals with projecting loops
or eyes so arranged that the several loops in one groove or depression will alternato
or break joints with those in the adjoining grooves, thereby strengthening the
plate; and it further partly consists in certain peculiarities of construction as
hereinafter set forth.
In the accompanying drawing illustrating the invention.
Figure 1 is a plan of my improved metallic foundation plate for lathing, showing
also several spiral laths in position.
Figure 2 is a section on the line x, x, of Figure 1 with spiral laths in place.
Figure 3 represents a portion of a wall or ceiling partly broken away to show
the underlying lathing.
Figure 4 is a section on the line y, y, of Figure 3, showing how the plastering or
cement covering is held in place.
Referring to the drawing the numeral 1 designates a metallic foundation plate
provided with parallel corrugations 2 and intervening channels or depressions 3,
the latter being formed at suitable intervals with projecting loops or eyes 4,
through which the laths 5 are passed from end to end of the several parallel
depressions.

page_text: The corrugated or channelled foundation plate is preferably rolled from sheet
metal by means of suitable corrugating rolls provided with devices for cutting the
channels 3 crosswise at proper intervals to form the marginal edges of the struck
up loops or eyes 4, said loops being thus continuous from end to end and integral
with the body of the corrugated plate.
In rolling the corrugated metallic plate the loop forming devices will be so
arranged as to locate the loops or eyes 4, at proper intervals to afford an adequate
fastening for the laths 5 to be passed through said loops.
The struck up loops or eyes 4, in the several grooves or depressions 3, may be so
arranged that the loops in the adjacent grooves will be in line with each other; or
they can be so arranged in each groove as to alternate or break joints with those
in the adjoining grooves, the latter arrangement being preferable by reason of its
greater strength.
This corrugated lathing foundation or support can be readily made in sections of
various definite lengths and breadths to facilitate fitting it to walls or ceilings of
various areas.
The corrugated metallic plates 1, are adapted to overlap at the sides and are to
be secured to wooden or iron studding, or walls and ceilings of a room, by common
nails, rivets or other suitable means with the metallic laths 5 lying in the channels
or depressions 3, and held in place by the loops or eyes 4, which form a firm
support therefor.
The form of lath which I prefer is the twisted or spiral metallic lath herein-
before referred to, though any suitable lath, either of wood or metal can be passed
through, and supported in the loops or eyes 4, formed on my improved corrugated
lathing foundation.
The laths aro preferably rounded at their ends to enable them to be passed
through the loops 4, with greater ease.
When the foundation and lathing are properly secured in place any desirable
plastic covering, cement or plastering can be spread thereon in the usual manner
and the plastic material 6, will be held firmly in place by becoming engaged with
the spiral laths 5 and within the corrugations formed on the foundation plate.
It will be observed that the loops or eyes 4, being integral with the foundation
plate and continuous from end to end are not liable to become broken off and
consequently will always afford a safer and durable support for the metallic lathing.
The form of these laths supporting loops or eyes is also such that a metallic
foundation plate provided therewith can be readily produced without great
expense. This lathing foundation is particularly useful in the construction of
fire proof buildings, though adapted also to other purposes. By its use the
plastering is firmly held against displacement, even under severe concussions, and
a firm and durable support is afforded for the most elaborate and ornamental
plaster-work.
After passing or threading the laths through the loops 4 the latter should be
driven or pressed firmly against the laths to hold them securely in place. This
I prefer to accomplish by means of a suitable roller or rollers, or by pressing the
lathing foundation and attached laths between suitable pressure plates. The
metallic lathing foundation with attached lathing, is then ready to be secured to
the walls or ceilings of a room. In placing the foundation plates or sections in
position, they should be over-lapped so as to secure tight and closed joints, thereby
obstructing the spread of fire from one room to another. By this means therefore,
the construction of fire proof buildings will be greatly improved.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim is :-
First. A lathing foundation having a series of parallel grooves or depressions
provided at intervals with lath supporting loops or eyes that are continuous from
end to end and extend across said grooves, substantially as described.

page_text: Second. A corrugated metallic lathing foundation having integral loops or eyes
for supporting the laths, substantially as described.
Third. A metallic lathing foundation formed with a series of parallel grooves or
depressions each provided at intervals with lath supporting loops, the loops in one
groove alternating with those in adjacent grooves, substantially as described.
Fourth. A metallic lathing foundation having a series of parallel corrugations
and intervening grooves or depressions provided with integral lath supporting loops
that are continuous from end to end and extend across said grooves or depressions
substantially as described.
Fifth. The combination with a metallic lathing foundation having a series of
parallel corrugations and intervening grooves provided with integral loops, of
metallic laths lying in said grooves and supported by said loops, substantially as
described.
