IMPROVEMENTS IN THE MANUFACTURE OF LINOLEUM AND IN MACHINES FOR CARRYING THE SAME INTO EFFECT
Year: 1885

page_text: I MORITZ HOFFBAUER, Director of the Erste Deutsche Patent Linoleum Fabrik,
of Cöpenick near Berlin in the Empire of Germany do hereby declare the nature
of my Invention for IMPROVEMENTS IN THE MANUFACTURE OF LINOLEUM AND IN
MACHINES FOR CARRYING THE SAME INTO EFFECT, 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 improvements in the manufacture of linoleum and in
machines for carrying the same into effect in order to be able to make linoleum of
special pattern consisting of a row or series of parallel strips of various colors and
of equal or varying breadth which are combined with or transferred to a common
breadth of sail cloth, canvas or other suitable material by the said machine in one
operation.
This object is attained by arranging an appropriate number of partitions above
the rollers to which the mass is fed so that the space between each two of these
said partitions serves to receive the mass for producing the said parallel strips or
stripes of various color according to requirements.
Figure 1 is an elevation.
Figure 2 a longitudinal section, and
Figure 3 a plan or top view of the said improved machine.
The two main rollers b and c between which the sail cloth, canvas or other fabric
and also the linoleum mass pass are journalled in the frame a.
The sail cloth or other fabric on the roller d is first guided over the two loose
rollers e and f in order to attain the necessary tension and is then lead to the main
roller b.
Between this said roller and the roller c I arrange a number of discs or
partitions g which are mounted on a fixed axis h and are so hollowed out that
they fit exactly onto the rollers and run almost to a tangential point below.
These said discs or partition walls are held by their own weight on the rollers
and so that the left recess or rounded cavity rests firmly on the sail cloth or other
fabric.
The axis h fits exactly between the framework so that no lateral movement can
take place.

page_text: The mass or material to be operated on to form linoleum is now placed by the
workman in the spaces between each two discs or partitions g each color in a
separate space or the mass can be automatically fed into the places in question by
employing suitable hoppers or other equivalent devices.
A space of like thickness with the discs or partitions remains between the
various parallel strips which however disappears as soon as the said mass has
passed the two rollers.
The linoleum is distributed in perfectly equable manner at all points the edges of
the separate parallel strips are quite sharp and form perfect boundary lines without
any free spaces or inaccuracies occurring."
In order to keep the two pressure rollers b, c smooth and free from particles of
linoleum two knives or scrapers k l are arranged in suitable position and in order
to be able to vary the thickness of the layer of linoleum two adjusting screws m
are so arranged that the bearings of the rollers bc can be adjusted as may be
desired.
The machine is driven from the shaft n which said shaft carries a toothed
wheel o which is in gear with a wheel p mounted on the one end of the shaft or
journal to the roller b.
The wheel mounted on the opposite end of the shaft or the opposite journal
of the roller b is in gear with the wheel r on the shaft or journal to the roller c so
that this said roller is rotated at like speed with the roller b.
The width of the spaces between each two discs g and consequently the width of
the stripes can be varied at will either by making the discs or partitions g
adjustable on the axis or shaft h or by making special axles or shafts and discs
or partitions for each width.
The material of the various stripes being colored throughout the wear and tear
of the said material will have no influence on and cause no alteration in the. color
of the same.
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
1-The improved method of manufacturing linoleum with stripes of various
colors and like or varying breadth or width by filling the colored material into
various spaces arranged above the pressure rollers substantially as and for the
purpose described in the foregoing specification.
2-In machines for manufacturing linoleum; the arrangement of a number of
discs or partitions g on a suitable shaft or axis h which said discs or partitions are
so formed or provided with curved recesses that the surfaces of the said discs or
partitions rest on the surface of the pressure rollers b c so as to form spaces or
compartments for the reception of the linoleum mass for manufacturing striped
linoleum colored throughout substantially as and for the purpose described and
shown in the accompanying drawings.
