PROVISIONAL SPECIFICATION.
The Manufacture of Improved Metal-cored Panels and the like,
chiefly designed for Use in the Construction of Buildings.
I, DAVID YOUNG, Patent Agent, of the Firm of D. Young & Co.,
11 and 12 Southampton Buildings, London, W.C., do hereby declare the nature of
this invention to be as follows :–
This invention relates to an improved material chiefly designed for use in the
construction of buildings (Vehrlin's system) specially characterized by its lightness
and strength, the said material being produced by the use of a metallic core.
This material is principally made in the form of squares or panels of large
dimensions but of small thickness, chiefly designed for use in the construction of
light partitions or facades.
'
These squares or panels are formed with a core, consisting of a perforated piece
of sheet iron or a metallic network or trellis surrounded by a composition of paper
pulp, sawdust, cork or the like, held together by any suitable binding material.
These compositions can, however, be replaced by antiseptic and absorbent
mixtures.
Whatever be the materials employed; the method of manufacture consists in
strongly compressing these materials onto each side of the metallio core by means
of rollers or presses.
.
In addition to being much thinner than the partitions actually made of bricks ór
squares of plaster, the partitions constructed with my improved material having a
metallic core can be made much thinner still.
For this purpose, the thickness of the coatings or layers of composition employed
is reduced; but as the latter, when in thin layers, would be liable to disintegration,
it is held in position by means of one or more layers of wide-meshed textile material,
which, when stretched from one part to another of the panel; unites with the said
composition and holds it together. The adhesion of the coatings or layers of
composition and textile material to the metallic core, is ensured by passing the
whole mass; formed as above mentioned, between rollers or under a press. The
panels made in this manner will only be a few millimeters thick. In practice, if it
be desired to employ the panels as partitions, for example, two rows of the said
panels are got up parallel to one another and held in position by brackets or the
like placed between them, and are secured by bolts passing through the whole.
Partitions can thus be produced having an internal air-space, which are highly
hygienic, non-sonorous and light.
:
In order to impart greater rigidity to the panels they can be undulated or
corrugated similarly to the sheets of zinc used for roofs. A partition with an air-
space can thus be made having undulated panels on one side, and flat panels on the
other side, the said panels being held together by bolts and having brackets or the
like interposed as above mentioned.
17
For ceilings the panels are formed with a piece of cloth, network or other textile
material hemmed onto the four walls or edges; into the hems are passed pieces of
hoop-iron: These panels are covered with a coating of zinc white, chloride of
zinc, and refractory earth.
For walls the panels are formed with a metallic network interwoven with cocoa-
aut fibre, hemmed with U-shaped sections of steel- and coated with the following
composition:-zinc white, chloride of zinc and wood sawdust.

page_text: It must understood that the metal-core materials can be applied to other
purposes than for the construction of partitions or facades. They can be used, for
example, in the construction of the floors or other portions of portable closets, or
in the construction of the walls of urinals, and for other purposes.
Instead of being flat they can be formed into any shape necessary for the
purpose for which they are to be employed.

The Manufacture of. Improved Metal-cored Panels and the like,
chiefly designed for. Use in the Construction of Buildings.
I, DAVID YOUNG, Patent Agent, of the Firm of D: Young & Co.,
11 and 12 Southampton Buildings, London, W.C., do hereby declare the nature of
this invention, (a communication to me from La Compagnie des Constructions
Démontables. et Hygiéniques, of Paris, in the Republic of France,) 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 an improved material chiefly designed for use in the
construction of buildings (Vehrlin's system) specially characterized by its lightness
and strength, the latter being obtained by the use of a metallic core..
This material is principally made in the form of squares, slabs. or panels of large
dimensions but of small thickness, chiefly designed for use in the construction of
light partitions or façades.
These squares or panels are formed with a core consisting of a piece of
perforated sheet iron or a metallic cloth or network surrounded by a composition of
papor pulp, sawdust, cork or the liko held together by any suitable binding material.
These compositions can however be replaced by antiseptio and absorbent mixtures.
Whatever be the materials employed, the method of manufacture consists in
strongly compressing these materials on to each side of the metallic core by means
of rollers, or presses.
In addition to being much thinner than the partitions at present made of bricks,
slabs or squares of plaster, partitions constructed with the improved building
material having a metallic core can be made much thinner still. ;
For this purpose the thickness of the coatings or layers of composition employed
is reduced; but, as the latter when in thin layers would be liable to disintegration,
it is held in position by means of one or more layers of wide meshed textile
material, which when stretched from one part to another of the panel, slab or
square unites with it and the said composition.
t
1.
The adhesion of the coatings or layers of composition, and textile material to
the metallic coro is ensured by passing the whole mass formed as above mentioned
between rollerstor underia press. The panels, slabs or squares made in this manner
will only be a few millimeters thick. In practice if it be desired to employ the
panels, slabs or squares as partitions for example, two rows of the said panels, slabs
or squares are arranged parallel to one another and held in position by brackets or
the like placed between them and are secured by, bolts passing through the whole.
Partitions can thus, be produced having an internal air space which are highly
hygienic, non-sonorous and light.
"
In order to impart greator rigidity to the panels, slabs or squares they can be
undulated or corrugated similarly to the sheets of zinc usad for roofs. A partition
with an air space can thus be made having undulated or corrugated panels, slabs or

page_text: squares on one side and flat panels, slabs or squares on tlie other side, the said
panels, slabs or squares being secured together by bolts and having brackets or
the like interposed between them as above mentioned.
For ceilings the panels, slabs or squares are formed of a piece of cloth network
or other textile material hemmed along the four edges; into the hems are passed
pieces or strips of hoop iron or other material. These panels, slabs or squares are
covered with a coating of zinc white, chloride of zinc and refractory earth..
For walls the panels, slabs or squares are formed with a metallic cloth or
network interwoven with cocoa fibre hemmed or bordered with U-shaped section<
of steel stitched or otherwise fixed thereto and coated with the following
composition, zinc white, chloride of zinc and wood sawdust.
It must be understood that the metal cored materials can be applied to other
purposes than for the construction of partitions or façades. They can be used for
example in the construction of the floors or other portions of portable closets .or
in the construction of the walls of urinals and for other purposes. Instead of
being flat they can be formed into any shape necessary for the purpose for which
they are to be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The above described new or improved building material, such material being
in the form of panels, slabs or squares, and consisting of a metallic core of
perforated sheet iron, metallic cloth, gauze or network covered on its two sides
with a mixture of paper pulp, or saw-dust, cork and antiseptic and absorbent
materials, combined by a suitable binding material, which when very thin are
Becured by one or several layers of cloth or other material having large meshes
strongly compressed on one or both sides of the pauels, slabs or squares which
latter may be corrugated or not and of any desired shape, substantially as herein
described!
2. The improved building material manufactured as herein described.
