Improvements relating to the Manufacture of Parquet Plates for
Floors, Ceilings, and the like.
I, GUSTAF UNDEN, of Lagerfars Brüg Moholm in the Kingdom of Sweden,
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of plates for parqueted floors, ceilings
and walls, tableplates and other similar articles.
Heretofore parquetry has been used consisting of wooden plates the edges of
which have been formed with grooves, the veneer being fastened by glue on one
side of same. These plates are laid directly on the floor and are kept together by
means of ribs or tongues, which are put into the coterminous grooves. Parquet
plates, which manufactured in this manner act as a kind of sound board, giving
out a rolling and noisy sound when walked upon. Moreover the wooden plates, to
which the veneer is fastened are liable to bend and alter its form according to the
moisture of the air, thus forming an uneven floor. The present invention obviates
the above mentioned objections and the plates made according thereto will satisfy
all reasonable requirements as to sanitation.
On account of these requirements the above mentioned wooden plates are united,
and replaced by a plastic material as for instance asphalt which withstands the
action of water. The use of this plastic material also obviates the necessity of
using glue as the veneer binds with a sufficient strength to the warm and plastic
asphalt.
In the manufacture of the improved parquet plates a frame of iron or other
suitable material may be used.
On a plane on the inside of the frame is placed the veneer consisting of one
or more different kinds of wood placed close together with the right side
downwards, and arranged according to the desired pattern.
Into the mould thus arranged where the bottom is formed by the said pattern of
veneer, while the sidewalls are formed by the frame itself, the warm asphalt is
poured with the addition of other suitable materials, if desired.
In order to strengthen the plates a number of wooden ribs or similar construc-
tions may be placed in different directions above the layer of veneer before the
frame is filled up with asphalt or the said ribs may be put down into the warm and
plastic material which is poured into the frame. To cause the veneer plates to
bind more rapidly to the asphalt they may be furnished on their rear side with
grooves or recesses or with projections of suitable form and extent.
In certain cases for instance when the plates are to be used as tableplates, it
may prove advantageous to cover even the sidewalls of the frame with veneer on
the inside.
When the asphalt is cooled, the plate is taken out of the frame, and the right
side of the veneer cleaned. This right side now forms inlaid work of wood with
a pattern, the composition and form of which depends on the nature of the wooden
0 pieces employed.
The manner in which these plates are joined for forming the floor ceiling or the
like, may be varied and does not form any part of the present invention. I am
aware that small pieces of wood are often placed on a bed of cement, asphalt or
similar material for making floors and also that the manufacture of plates of

page_text: asphalt for sidewalks and the like is effected by pouring asphalt into moulds:
provided with ribs of wood or similar material.

COMPLETE SPECIFICATION.
Improvements relating to the Manufacture of Parquet Plates for
Floors, Ceilings, and the like.
I, GUSTAF UNDEN, of Lagerfars Brüg Moholm, in the Kingdom of Sweden,
Manufacturer, 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 :-
This invention relates to the manufacture of plates for parqueted floors, ceilings
and walls, tableplates and other similar articles.
Heretofore parquetry has been used consisting of wooden plates, the edges of
which have been formed with grooves, the veneer being fastened by glue on one
side of the same. These plates are laid directly on the floor and are kept together
by means of ribs or tongues, which are put into the coterminous grooves. Parquet
plates, manufactured in this manner act as a kind of soundboard, giving out a
rolling and noisy sound when walked upon.
Moreover the wooden plates, to which the veneer is fastened are liable to bend
and alter their form according to the moisture of the air, thus forming an
uneven floor.
The present invention obviates the above mentioned objections and the plates
made according thereto will satisfy all reasonable requirements as to sanitation.
On account of these requirements the above mentioned wooden plates are omitted,
and replaced by a plastic material as for instance asphalt which withstands the
action of water. The use of this plastic material also obviates the necessity
of using glue as the veneer binds with a sufficient strength to the warm and
plastic asphalt.
In the manufacture of the improved parquet plates a frame of iron or other
suitable material may be used.
On a plane on the inside of the frame is placed the veneer consisting of one or
more different kinds of wood placed close together with the right side downwards,
and arranged according to the desired pattern.
Into the mould thus arranged where the bottom is formed by the said pattern of
veneer, while the sidewalls are formed by the frame itself, the warm asphalt is
poured with the addition of other suitable materials if desired.
In order to strengthen the plates a number of wooden ribs or similar con-
structions may be placed in different directions above the layer of veneer before
the frame is filled up with asphalt, or the said ribs may be put down into the warm
and plastic material which is poured into the frame.
To cause the veneer plates to bind more rapidly to the asphalt, they may be
furnished on their rear side with grooves or recesses or with projections of suitable
form and extent.
In certain cases for instance when the plates are to be used as table-plates
it may prove advantageous to cover even the side-walls of the frame with veneer
on the inside.
When the asphalt is cooled, the plate is taken out of the frame, and the right
side of the veneer cleaned. This right side now forms inlaid work of wood with a
pattern, the composition and form of which depends on the nature of the wooden
pieces employed.

page_text: The manner in which these plates are joined for forming the floor ceiling or the
like, may be varied and does not form any part of the present invention. I am
aware that small pieces of wood are often placed on a bed of cement, asphalt or
similar material for making floors and also that the manufacture of plates of
asphalt for side-walks and the like is effected by pouring asphalt into moulds
provided with ribs of wood or similar material and I do not therefore desire to.
claim broadly parquet plates consisting of wood and asphalt, but only such plates
of wood and asphalt and similar material which are further characterised in the-
following claims.
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 :-
First. Parquet plates for covering floors, walls, ceilings and the like and which.
may also be used as table-plates and similar articles, consisting of a plate of
asphalt mixed with other substances, one side of the plate being entirely covered
with a layer of veneer adhering to the asphalt and arranged according to.
certain patterns, strengthening ribs, of wood or similar materials being placed in
the asphalt plate.
Second. The method of making parquet plates characterized in the first claim
which consists in arranging the veneer according to the desired pattern on a plane
enclosed in a frame whereon the warm asphalt mixed with other substances is
poured, strengthening loose or fixed ribs being placed in the frame before it is
mass while it is still in a
filled with asphalt or pressed down into the
plastic state.
