I, ERNEST HOMAN of 17 Gracechurch Street, in the City of London, Engineer,
do hereby declare the nature of this invention to be as follows:-
The invention relates to improvements in or connected with the construction
of walls, partitions, ceilings or the like.
In modern buildings thin party walls are sometimes formed by arranging
vertically and edgewise at intervals metal laths across the. edges of which is
strained, wire work, wire gauze or the like to afford a key to the plaster of which
the wall is formed and which is filled in between and over the laths but walls
of this character are expensive and the object of the present invention is to cheapen
the construction thereof.
In carrying the present invention into effect the strained wire work or its
equivalent is dispensed with and the framework of the wall is composed of a
number of laths or strips of iron of a suitable width, generally that which is
commonly known as hoop iron would be employed and this material is formed
by passing it between suitably shaped rolls or otherwise with a number of tongues
or tangs which are pressed out at intervals from opposite sides of the metal.
In constructing a wall with metal laths of this character, a sufficient number of
strips to form the required length of the wall are arranged preferably vertically
and edgewise at suitable intervals, which may be for example slightly greater
than the length of two tongues, by bending their ends over and nailing or other-
wise fastening them to the rafters or joists or other means of support, the tongues
or tangs are then opened out so as to project laterally from the faces of the laths
in such manner that their points nearly meet and the plaster to form the body
of the wall is filled in between and over the edges of the laths from each side of
the structure or from one side of a wood centering or backing is temporarily held
against the opposite side so as to completely conceal the laths and when the plaster
has become set the wall may be finished in any desired manner.
Although the invention is herein before described as applied to a wall it will
be evident that it is also applicable 'to ceilings or the like.
By these means the plaster is more efficiently keyed with the laths than hereto
fore, added to which advantage the cost of 'the strained wire work or its equivalent
covering is practically saved, the expense of forming the tongues or tangs upon
the laths being very small.

I, ERNEST HOMAN of 17 Gracechurch Street, in the City of London, 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:-
The invention relates to improvements in or connected with the construction
of walls, partitions, ceilings or the like.
In modern buildings thin party walls are sometimes formed by arranging
vertically and edgewise at intervals metal laths across the edges of which is
strained wire work wire gauze or the like to afford a key to the plaster of which
the wall is formed and which is filled in between and over the laths but walls
of this character are expensive and the object of the present invention is to cheapen
the construction thereof.
In carrying the present invention into effect the strained wire work or its
equivalent is dispensed with and the framework of the wall is composed of a
number of laths or strips of iron of a suitable width, generally that which is
commonly known as hoop iron would be employed and this material is formed
by passing it between suitably shaped rolls or otherwise with a number of tongues
or tangs which are pressed out at intervals from opposite sides of the metal.
In constructing a wall with metal laths of this character, a sufficient number of
strips to form the required length of the wall are arranged preferably vertically
and edgewise at suitable intervals which may be for example slightly greater
than the length of two tongues, by bending their ends over and nailing or other-
wise fastening them to the rafters or joists or other means of support the tongues
or tangs are then opened out so as to project laterally from the faces of the laths
in such manner that their points nearly meet, and the plaster to form the body
of the wall is filled in between and over the edges of the laths from each side of
the structure or from one side of a wood centering or backing is temporarily held
against the opposite side so as to completely conceal the laths and when the plaster
has become set the wall may be finished in any desired manner.
Although the invention is herein before described as applied to a wall it will
be evident that it is also applicable to ceilings or the like.
:
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical longitudinal section of a portion of a wall or partition
constructed according to the present invention..
Figure 2 is a transverse section thereof taken on the line 1-1 of Figure 1.
Figure 3 is an edge view of one of the tongued laths or strips previous to
opening out the tongues.
Figure 4 is a similar view to Figure 3 but showing the tongues opened out.
Figure 5 is a face view of Figure 4, and
Figure 6 is a vertical section of a ceiling constructed according to the present
invention.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 5 a represents the wooden bearers of the wall, 6 re-
presents the plaster or cement, and c represents the metal laths or strips.
The laths are formed by passing them between suitably shaped rolls or other-

page_text: wise with a number of tongues or tangs c¹ which are pressed out at intervals from
opposite sides of the metal as represented at Figure 3.
In constructing a wall with metal laths a sufficient number of laths or strips c
to form the required length of the wall are arranged preferably vertically and
edgewise at suitable intervals which may for example be slightly greater than the
length of two tongues c¹ as represented at Figures 1 and 2.
In order to fix the laths or strips c to the bearers a their ends are bent at
right angles to the body thereof as represented more particularly at Figures 1
and 4, and the returned ends or flanges receive nails or other fastening means d
by the aid of which the strips or laths c are securely fastened to the rafters or
joists a or other means of support.
The tongues or tangs el are then opened out from the body c of the lath or strip
as represented at Figures 1, 2, 4, and 5, so as to project laterally at right angles
from the faces of the laths or strips c in such manner that the points of the tongues
or tangs el nearly meet, and the plaster or cement b to form the body of the wall
is filled in between and over the edges of the laths e from each side of the structure
or it might be from one side thereof if a wood centering or backing were tem-
porarily held against the opposite side in such manner that the plaster completely
conceals the laths or strips c and when the plaster has become set the wall may
be finished in any desired manner.
In the example given at Figure 6 which represents a ceiling constructed
according to the present invention the ends of the laths or strips c instead of
being bent round or returned in the manner shown in the previous figures are
twisted so as to receive nails, screws, or fastenings d by means of which the laths
or strips c are securely fixed to the joists a with the body of the laths or strips
arranged vertically and edgewise to the thickness of the plaster forming the
ceiling.
By these means the plaster is more efficiently keyed with the laths or strips c
than heretofore added to which advantage the cost of the strained wire work or
its equivalent covering is practically saved the expense of forming tongues or
tangs cupon the laths or strips c being very small.
It will be evident that the invention is also applicable to other like structures
than those herein before shown and described.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. A wall, partition, ceiling or the like comprising suitable supports or bearers
strips or bands of metal fastened to and extending between the bearers or supports
and formed with projecting tongues or tangs, and a filling of plaster or cement
substantially as herein shown and described.
2. A strip or band of metal formed with tongues or tangs pressed out of the
body thereof and adapted to form an integral part of a wall, partition, ceiling,
or the like substantially as herein shown and described.
