Improvements in Apparatus for Manufacturing Mosaic Floor Cloths
and the like.
I, FREDERICK WALTON, of No. 4 Portugal Street, Lincolns Inn Fields, in the
County of London, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to apparatus for manufacturing mosaic floor cloths and the
like, the chief object which I have in view being to effect this manufacture by a
continuous process. For this purpose, I provide, in the first place, a cylinder with
a number of pins projecting from its circumference and I arrange around part of
this cylinder several other cylinders which I may term cutting cylinders one for each
colour of the mosaic pattern that is to be produced. These cutting cylinders have
projecting knives shaped and arranged according to the pattern and in the spaces
between the knives they have radially sliding pistons or plungers.
Between each of these cutting cylinders and a pressing cylinder passes, a
continuous sheet of the material that is to form the mosaic, each sheet, it may be,
of a different colour. A fabric backing passes between the first of these cutting
cylinders and the pin cylinder and continues round the latter to the point of
discharge. As the cylinders revolve each cutting cylinder cuts out of the sheet
which is in contact with it a series of pieces according to pattern and each piece as
it is brought round to the point of contact with the pin cylinder is forced out by the
piston or plunger from between the knives on to the pin cylinder on which it is
held by the pins projecting through the backing fabric. In like manner pieces of
different colours are pressed from the other cutting cylinders on to the backing and
are carried round by the pins projecting into them. After passing the last of the
cutting cylinders the backing is led off, with the mosaic pieces on it, on to a heating
cylinder partly around which there is an endless band pressing the backing and
mosaic pieces against the beating cylinder. Finally the backing and mosaic pieces
on it are subjected to the pressure of adjustable pressing rollers which cause the
mosaic pieces to cohere to each other and adhere to the backing, and thereupon
the sheet of mosaic is carried round suitable cooling rollers until the material sets.

I, FREDERICK WALTON of No. 4 Portugual Street, Lincolns Inn Fields, in the
County of London, 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:—

each of these cutting cylinders and a pressing cylinder passes a continuous sheet of
the material that is to form the mosaic, each sheet may be of a different colour. A
fabric backing passes between the first of these cutting cylinders and the pin
cylinder and continues round the latter to the point of discharge. As the cylinders
revolve each cutting cylinder cuts out of the sheet which is in contact with it a
series of pieces according to pattern, and each piece as it is brought round to the
point of contact with the pin cylinder is forced out by the piston or plunger from
between the knives on to the pin cylinder on which it is held by the pins projecting
through the backing fabric. In like manner pieces of different colours are pressed
from the other cutting cylinders on to the backing and are carried round by the
pins projecting into them. After passing the last of the cutting cylinders the
backing is led off with the mosaic pieces on it on to a heating cylinder partly around
which there is an endless baud pressing the backing and mosaic pieces against the
heating cylinder. Finally the backing and mosaic pieces on it are subjected to the
pressure of adjustable pressing rollers which cause the mosaic pieces to cohere to
each other and adhere to the backing, and thereupon the sheet of mosaic is carried
round suitable cooling rollers until the material sets.
The accompanying drawings represent a machine according to my invention,
arranged to operate as above described.
Figure I is a side elevation of that part of the machine where the mosaic tesserae
are cut and set.
Figure II is a side elevation of the part for pressing.
Figures III and IV are plans of the parts shewn in Figures I and II.
Figure V is an end view, and
Figure VI is a part longitudinal section of one of the cutting cylinders.
Figure VII is a part longitudinal section of its interior.
In the several figures the same letters of reference indicate corresponding
parts,
A are the side frames of the tesserae cutting and setting machine, between which
frames turns a large drum B having on it a large number of projecting pins with
which it may be furnished by jacketting it with carding material made with straight
dents or pins which project just far enough to pass through the backing of the
linoleum to be produced and to enter but not to pass through the tesserne placed on
the backing.
The backing is led by an endless apron or blauket G, or it might be by steel
bands provided with pins, to the drum B and is pressed and so pinned to the drum
by the roller E which is jacketed with felt, the pressure being regulated by the
screws M
The backing is carried by the drum B between it and the cutting rollers H shewn
to an enlarged scale in Figures V, VI and VII.
The two heads of these rollers are connected by sections m of a metal shell on
which are fixed the cutting blocks which are likewise inade in sections meeting
each other so that they cover the whole circumference of the roller.
The cutting blocks i have projecting knives so shaped and set as to cut the
tesserae to the pattern of the fabric to be produced.
For pushing the cut out tesserne on to the backing to be held by the pins
projecting through the backing, the rollers are provided with sliding plates or
plungers which have stems / with their ends resting on the pushing plates n. In
the heads of the cutting rollers are slots in which move blocks which are pressed
towards the axis of the roller by springs g.
Within the rollers the sections of shell are loosely screwed on the blocks and
outside the roller, sections o are similarly screwed on the blocks f so that they
together form a ring allowing a slight deviation from a circle at the parts where
the sections meet.
Each cutting roller H has its axis running in a block a
slot in which a stud c can be set more or less away from the
This block has a
axis of H. Ou the

page_text: stud c is a roller which presses against the inside of the ring o forcing it
towards the drum B.
As the roller H rotates, the sections of o are successively pressed towards the
circumference of H and as the sections a are moved with them, the plungers / are
pushed forwards delivering the cut out tesserae on the pins which project through
the backing. In order that the tesserae may be delivered in proper register by the
rollers H, these rollers can be turned on their shifts and fixed in proper register
by set screws.
The rollers H have pinions C¹ driven from the wheel C.
Against the rollers H work the rollers I the hearings of which by screws L are
pressed against H. The rollers I are driven by their frictional contact with H and
are jacketed with elastic material.
The rollers J deliver on an endless blanket or band q sheets of linolean p which
pass between the rollers I and H having the tesserae cut out from them.
To prevent the cutting rollers H from being pressed too much by the screws L
acting on the rollers I against the drum B, their position is determined by setting
screws & which adjust the blocks a.
The tesserae are so cut out that the linoleum sheet p after having passed the
rollers I H forms still a continuous sheet with parts of it cut out, which sheet is
led hetween endless blankets or bands q carried by rollers K.
The rollers J and K are driven by their endless blankets or belts from the
machines which produce the linoleum sheets, at speed corresponding with that of
the rollers H and drum B.
The backing S with the tesserae set on it passes between B and a roller F
(which is pressed against B by screws M) to the pressing machine Fig. II.
Within the frame N is driven by the gearing D D a steam heated cylinder O
made with a polished surface. It is partly enclosed in a strong endless blanket R
carried by the rollers P which are mounted in brackets Q, these brackets being
adjustable on the frame N so that the blanket can enclose more or less of the
cylinder O.
A roller T adjusted by screws U gives the necessary tension pressing the
blanket against the cylinder O and thus squeezing the fabric which passes between
the cylinder O and the blanket.
The backing S with the tesserne fixed on it by the pressure is afterwards
subjected to the action of cooling cylinders.
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. In apparatus for manufacturing mosaic floor cloth, the combination of a drum
with projecting pins, a number of cutting rollers and corresponding pressing rollers
arranged around the drum, so that backing fabric carried round with the drum
between it and the cutting rollers has placed on it and held by the pins passing
through it tesserae of various shapes and colours forming together the mosaic
pattern, substantially as described.
2. In combination with the tesserae cutting and setting apparatus above set forth,
the pressing machine consisting of a polished heated roller between which and a
strong strained apron the backing and tesserae pass, substantially as described.
