I WILLIAM CHARLES SCHAPIR Gentleman, residing at No 2726 Dayton
Street in the City of St Louis, State of Missouri, United States of America, do
hereby declare the nature of this invention to be as follows
My invention relates to an improved metallic lathing for supporting the plaster
upon the interior or extenor of buildings, and consists in the novel features of
construction hereinafter described
The object of my invention is to construct from single sheets of metal a metallic
lathing that is simple, durable, inexpensive, especially strong and that requires
less plaster to a given area than is required by metallic lathings of other
constructions
A further object of my invention is to provide a metallic lathing that will be
especially efficacious in holding the moitar in place
A further object of my invention is to so locate and form the proti uding lips on
the sheets of metal as that all expansion and contraction of the sheets during the
formation of the lathing will be almost entirely overcome
I employ a body or sheet of metal of any suitable size and thickness
The means
employed to form the corrugations, slits, lips, etc, in the sheet metal body may
vary as desired, as numerous metho ls, such as stamping, pressing, or passing the
sheet metal sections through rollers specially formed will accomplish the desired
result
The base is that portion that rests or engages directly against the rafters, boards,
or to whatever the lathing is secured, said base remaining intact and occupying
the plane originally occupied by the upwardly bent portions of the lathing
Extending upwardly from the base and parallel with each other are lips or
corrugations The ends of these coriugations are rounded, and in the rear of said
corrugations at the point where they are bent upwardly from the base is formed
longitudinal slits, the edges of which are bent into a plane approximately that of
the inner edges of the corrugations This will necessarily form valleys or
depressions in the longitudinal corrugations
Strips are preserved between the corrugations and are bent into a plane slightly
below the plane occupied by the base Extending longitudinally of these strips
are upwardly projecting ribs A portion of the base is bent into a plane
approximately half way between that of the base and the upper inner edges
of the corrugations
I have found that by alternately forming the pairs of lips or corrugations at
right angles to one another in their parallel lines, the expansion and contraction of
the sheets of metal is entirely overcome Thus by my improved construction,
buckling, bending on breaking of the sheets of metal during the formation of the
corrugations thei ein, and deleterious results from heat, cold, moisture, etc, are
entirely prevented In the raised portion of the sheets between the pairs of
coniugations are rectangular apertures, the edges of which are bent upwaidly and
then inwardly, said inwardly bent portions terminating in the same plane with the
upper uner edges of the lips or corrugations
In some cases, the lips or corrugations may be dispensed with and strips
provided with longitudinal V-shaped depressions are bent upwardly from the base.

page_text: These strips are alternately formed at right angles to one another, in order to
overcome the contraction and expansion of the metal, as previously stated
In the upwardly bent portion of the section are formed rectangular opening,
inner edges of which are bent upwardly and inwardly
the
In some instances a portion of the section is ben into a plane approximately
half way between that of the base and of the upper inner edges of the corrugations
In the formation of the corrugations in this instance, I have found it desirable to
alternate said corrugations in their parallel lines, though if desired said corrugations
may be formed in parallel 1 nes in both directions In said bent portion and
between the pairs of alternated corrugations are triangular apertures, the edges of
which are bent in a vertical plane, or at right angles to the bent portion, in some
instances, the strip may be dispensed with, the corrugations being bent up from a
centrally formed slit
In the practical use of my improved lathing, it is applied to the interior walls
and ceilings of buildings in the ordinary manner, and the mortar applied directly
upon the face of said lathing, said mortar being plastic, it will readily enter the
space between the edges of the lips or corrugations, and as pressure is applied to
said mortar, it will contact with the longitudinal strips and by said strip be
deflected in opposite directions By reason of this deflection, portions of the
mortar will engage beneath the lips and corrugations and when said mortar becomes
hardened it will be very firmly keyed or held in position upon said lathing
A portion of said mortar will also enter the shits beneath the adjacent portions, and
also through the rectangular apertures or openings and engage beneath the
inwardly bent edges of said apertures Thus will be seen how the mortar
will be firmly positioned upon the face of the lathing and the liability of
the same becoming broken or disengaged therefiom reduced to a minimum
By bending the major portion of the sheet section into a plane slightly above
that occupied by the base portion, it will be seen how a smaller quantity of
mortar will be required to cover a given surface than if metallic lathing of the
ordinary construction be used It will also be seen that by bending or forming the
body of the sheet section into two different planes, said section will be greatly
increased in strength and lasting qualities
As herein before stated, by forming the bases from which extend or protrude the
lips or corrugations alternately at right angles to each other, the expansion and
contraction of the sheets of metal during the formation of the corrugations or lips,
and also when the lathing is in practical use, will be entirely overcome
Thus will be seen how I have constructed a metallic lathing that possesses
superior advantages in point of simplicity, durability and general efficiency

I, WILLIAM CHARLES SCHAPER, Architect, of Room 200, Fagin Building,
810 Olive Street, St Louis, Mo United States of America, 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
-
My invention relates to an improved metallic lathing for supporting the plaster
upon the interior and exterior of buildings and consists in the novel features of
construction hereinafter described and claimed
The object of my invention is to construct from single sheets of metal a metallic

page_text: Jathing that is simple, durable, inexpensive, especially strong and that requires less
plaster to a given area than is required by metallic lathings of other constructions
A further object of my invention is to provide a metallic lathing that will be
especially efficacious in holding the mortar in place
A further object of my invention is to so locate and form the protruding lips on
the sheets of metal so that all expansion and contraction of the sheets during the
formation of the lathing will be almost entirely overcome

Fure 14 is a sectional view on the line 14-14 of Figure 13
Figure 15 is a sectional view on the line 15-15 of Figure 13
Figure 16 is a sectional view on the line 16-16 of Figure 13
Referring by numerals to the first seven views of the accompanying drawings,
1 indicates the body or sheet of metal out of which the lathing is formed, said
sheets of metal being of any suitable size and thickness The means employed to
form the coniugations, slits, lips, etc, in the sheet metal body may vary as desired,
as numerous methods, such as stamping, pressing or passing the sheet metal sections
through rollers specially formed will accomplish the desired result
The shaded portion, indicated by the numeral 2, is that portion that rests or
engages directly again t the rafters, bond, or whatever the lathing is secured to,
and may be properly termed the base of the lathing, this base 2 remaining intact
and occupying the plane originally occupied by the upwardly bent portions of the
lathing Extending upwardly from the base 2 and parallel with each other are
lips or corrugations 3, the inner faces or edges of said corrugations being indicated
by the numeral 4 The ends of these corrugations are rounded, as indicated by 5,
and in the rea of said corrugations at the point where they are bent upwardly
from the base 2 is formed longitudinal slits 6, the edges 7 of which are bent into a
plane approximately that of the inner edges 4 of the corrugations
neces arily form valleys or depressions 8 in the longitudinal corrugations 3
Strips 9 are preserved between the corrugations 3 and are bent into a plane
slightly below the plane occupied by the base 2 Extending longitudinally of these
strips 9 are upwardly projecting ribs 10 The portion 11 of the base 2 is bent
into a plane approximately half way between that of the base 2 and the upper
inner edges of the corrugations 3
This will
I have found that by alternately forming the pairs of lips or corrugations at
right angles to one another in the parallel lines, the expansion and contraction of
the sheets of metal is entirely overcome
Thus by my improved constructions, buckling, bending, or breaking of the sheets
of metal during the formation of the corrugations therein, and deleterious results
from heat, cold, moisture, etc, are entirely prevented In the raised portion 11 of
the sheets 1 & 5 between the pairs of corrugations are rectangular apertures with
a straight slit, 12 and the edges or lips 13 of which are bent upwardly and then

page_text: inwardly, said inwardly bent portions terminating in the same plane with the upper
inner edges 4 of the lips or corrugations 3
In the modified form of lathing shown in Figure 5, the lips or corrugations 3 are
dispensed with and strips 14 provided with longitudinal V-shaped depressions 15
are bent upwardly from the base 2
These strips 14 are alternately formed at
right angles to one another, in order to overcome the contraction and expansion of
the metal, as previously stated
In the upwadly bent portions 11 of the Figure 1 are formed rectangular
openings 6 the inner edges of which are bent upwardly and inwardly, as indicated
by 7
Referring by numerals to Figures 8 to 16 inclusive, in the drawings 18 indicates
the body or sheet of metal out of which the lathing is formed it being of suitable
thickness The method of forming the corrugations, slits, lips, etc, in the sheet
metal body may vary, as various methods, such as stamping, pressing or passing
the sheet metal bodies through rollers specially formed will accomplish the result
The shaded portion, indicated by the numeral 19, 1s that portion that rests or
engages directly against the rafters, boards, or to whatever the lathing is secured
and may be properly termed the base of the lathing This base 19 iemains intact
and occupies the plane originally occupied by the upwardly bent portions of the
lathing At stated distances in the Figure 1 and extending in horizontal alignment
are pans of upwardly projecting lips or corrugations 20, the inner faces of said
corrugations being indicated by the numeral 21 The ends of these corrugations
are rounded, as indicated by the numeral 22, and in the rear of these corrugations
at the point where they tuin upward from the base 19 is formed a longitudinal
slip 23, the edge 24 of which is bent into a plane with that of the inner edges of
the corrugations This will necessarily form depressions or valleys 20 in the
longitudinal corrugations 20
Strips 26 are preserved between the corrugations 20 and in the same plane as
the base 19
The portion 27 of the section 18 is bent to a plane approximately half way
between that of the base 19 and of the upper edge 21 of the corrugations 20
In the formation of the corrugations in the section 18, I have found it desirable
to alternate said corrugations in the parallel lines, though if desired, said
corrugations may be formed in parallel lines in both directions
In the portion 27 and between the pans of alternated corrugations 20 are
triangular apertures 28, the edges of which are bent in a vertical plane, or at right
angles to the portion 27, said upturned portions being and cated by the numeral 29
In the modified form shown in Figure 13, the strip 26 is dispensed with, the
corrugations 20 being bent up from a centrally formed slit 30
In the practical use of my improved lathing it is applied to the interior walls
and ceilings of buildings in the ordinary manner, and the mortar applied directly
upon the face of said lathing, said mortar being plastic, it will readily enter the
space between the edges of the lips or corrugations, and as pressure is applied to
said mortar, it will contact with the longitudinal strips, and by said strips be
deflected in opposite directions By reason of this deflection, portions of the
mortar will engage beneath the lips and corrugations and when said mortar becomes
hardened it will be firmly keyed or held in position upon said lathing A portion
of said mortar will also enter the slits between the adjacent portions, and also
through the icctangular apertures or openings and engage beneath the inwardly
bent edges of said apertures Thus it will be seen how the mortal will be firmly
positioned upon the face of the lathing and the liability of the same becoming
broken or disengaged therefrom reduced to a minimum By bending the major
portion of the sheet section into a plane slightly above that occupied by the base
portion, it will be seen how a smaller quantity of mortar will be required to cover
a given surface than if metallic lathing of the ordinary construction be used
It
will also be seen that by bending or forcing the body of the sheet section into two

page_text: different planes, said sections will be greatly increased in strength and lasting
qualities
As hereinbefore stated, by forming the bases from which extend or protrude the
lips or corrugations alternately at right angles to each other, the expansion and
contraction of the sheets of metal dui ing the formation of the corrugation or lips,
and also when the lathing is in practical use, will be entirely overcome
Thus it will be seen how I have constructed a metallic lathing that possesses
superior advantages in point of simplicity, durability, and general efficiency
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,
