PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Mosaic
Floor Cloth.
I, FREDERICK WALTON, of No. 114 Holborn, in the City of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
In my previous Specifications No. 6039 of 1882, No. 16338* of 1888 and
No. 16043 of 1890 have described processes and apparatus for the manufacture of
mosaic floor cloth, by cutting tessera or pieces of various patterns from variously
coloured sheets of material of linoleum character, and cementing and pressing these
pieces side by side on a backing of fabric. As the blocks and cylinders employed
for cutting the tesseræ are very costly in construction it is impossible to provide
for a number of different mosaic patterns except at very great expense.
pass
My present invention relates to means whereby I can render one set of cutting
cylinders available for many different mosaic patterns when these are of a
geometrical kind, as they usually are, capable of being made up by the aggregation
of numbers of equal and similar elementary figures such, for instance, as isosceles
right angled triangles, by the various groupings of which, squares, rectangles,
crosses and many other figures can be produced. Assuming that the mosaic is to
be produced in four colours, I employ 4 pressing and 4 cutting cylinders and I
a sheet of material of each colour between one of the pressing and one of the
cutting cylinders whereby the sheet is cut into as many elementary tesseræ as there
are spaces between the cutters of the cutting cylinder, one of the tessere being
retained in each space.
As the cutting cylinder revolves, before it brings the
tessera which it contains round to the position where they are pressed upon the
fabric by means of internal cams and plungers, all the tessera which are not to be
pressed on the fabric are extruded by means of another set of internal cams and
plungers, or are extracted in succession by the action of a revolving cylinder from
which project a number of curved pickers. These pickers are fixed in such
positions on their cylinder as to coincide with all the tessera lodged in the cutting
cylinder that have not to form part of the pattern. All these being thus pushed
or picked out, only those which are left in and which are intended to form part of
the pattern, are carried round by the cutting cylinder and deposited on the fabric.
As the pickers continue their revolution carrying on them the tessera which they
had picked out, they pass through between the teeth of a stationary inclined comb
which clear the tesseræ off the pickers, leaving them free to effect repeated picking
as they continue their revolution.
As one cutting cylinder, made with cutters for elementary tesseræ, may serve for
many different patterns, so one picking cylinder may be made to serve for as many
different patterns. For this purpose, I make the picking cylinder with as many
holes in its circumference as there are spaces for tesseræ in the cutting cylinder,
one hole in position to face each tesseræ ; and I screw or otherwise fix pickers in
such of these holes as may be required for the particular pattern that has to be
produced.
Instead of cutting the tesseræ from a sheet by means of a cutting cylinder as
above described, they may be formed by compressing powdered material in the
spaces between partitions of a moulding cylinder, which partitions are arranged in
the same way as the knives of a cutting cylinder. The tesseræ thus moulded may
be extruded and extracted in the same way as the cut tesseræ.

Floor Cloth.
I, FREDERICK WALTON, of No. 114 Holborn, in the City 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 :-
In my previous Specifications No. 6039 of 1882, No. 16338* of 1888 and
No. 16043 of 1890 I have described processes and apparatus for the manufacture
of mosaic floor cloth, by cutting tesseræ or pieces of various patterns from
variously coloured sheets of material of linoleum character, and cementing and
pressing these pieces side by side on a backing of fabric. As the blocks and
cylinders employed for cutting the tesseræ are very costly in construction, it is
impossible to provide for a number of different mosaic patterns except at very
great expense.
My present invention relates to means whereby I can render one set of cutting
cylinders available for many different mosaic patterns when these are of a
geometrical kind, as they usually are, capable of being made up, by the aggregation
of numbers of elementary figures such, for instance, as isosceles right angled
triangles, by the various groupings of which, squares, rectangles, crosses and many
other figures can be produced. Assuming that the mosaic is to be produced in
four colours, I employ 4 pressing and 4 cutting cylinders and I pass a sheet of
material of each colour between one of the pressing and one of the cutting
cylinders, whereby the sheet is cut into as many elementary tesseræ as there are
spaces between the cutters of the cutting cylinder, one of the tessere being retained
in each space.
As the cutting cylinder revolves, before it brings the tesseræ
which it contains round to the position where they are pressed upon the fabric by
means of internal cams and plungers, all the tessera which are not to be pressed
on the fabric are extruded by means of another set of internal cams and plungers,
or are extracted in succession by the action of a revolving cylinder from which
project a number of curved pickers. These pickers are fixed in such positions on
their cylinder (which may be termed the clearing cylinder) as to coincide with all
the tessere lodged in the cutting cylinder that have not to form part of the pattern.
All these being thus pushed or picked out, only those which are left in and which
are intended to form part of the pattern, are carried round by the cutting cylinder
and deposited on the fabric. As the pickers continue their revolution carrying on
them the tessera which they had picked out, they pass through between the teeth
of a stationary inclined comb which clear the tesseræ off the pickers, leaving them
free to effect repeated picking as they continue their revolution.
As one cutting cylinder made with cutters for elementary tesseræ, may serve for
many different patterns, so one clearing cylinder may be made to serve for as many
different patterns. For this purpose, I make the clearing cylinder with holes in
its circumference suited to the spaces for tesseræ in the cutting cylinder, one hole
or several holes in position to face each tesseræ ; and I screw or otherwise fix
pickers in such of these holes as may be required for the particular pattern that
has to be produced.
Instead of cutting the tesseræ from a sheet by means of a cutting cylinder as
above described, they may be formed by compressing powdered material in the
spaces between partitions of a moulding cylinder which partitions are arranged in
the same way as the knives of a cutting cylinder. The tesseræ thus moulded may
be extruded and extracted in the same way as the cut tesseræ.
:
The accompanying drawings illustrate by way of examples how a cutting or
moulding cylinder with its knives or partitions arranged to form elementary figures

page_text: may be employed to produce different patterns. Thus a cylinder with knives or
partitions arranged as in Fig. 1 to form a number of right angled isosceles triangles
each being half of a square cut along its diagonal, may be employed to produce
patterns such as those represented by Figs. 2, 3 and 4, different colours in these
being indicated by hatching lines drawn in different directions.
In like manner, a cylinder with its knives or partitions arranged as circles
intersecting each other as in Fig. 5 may be employed to produce different patterns,.
one example of which is represented in Fig. 6.
The clearing cylinders to operate in conjunction with the cutting cylinders
should have a hole to receive a picker in a position corresponding to the middle of
each of the elementary figures of the cutting cylinder. Thus a clearing cylinder
to be used with the cutting cylinder Fig. I would have holes for pickers in its
periphery arranged as indicated at A Fig. 1, and a clearing cylinder to be used
with the cutting cylinder Fig. 5 should have holes for pickers arranged as indicated
at B Figure 5.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A cutting or moulding cylinder for the manufacture of mosaic floor cloth,
having its knives or partitions arranged to form elementary figures such that
tesseræ produced by one such cylinder can be grouped with tesseræ produced from
other such cylinders to form patterns which may be varied according to the tesseræ
selected in each case for grouping, substantially as described.
2. A clearing cylinder to be employed in conjunction with a cutting cylinder
such as is above referred to, the said clearing cylinder having in its periphery
holes for the fixing of pickers, corresponding with the elementary figures of the
cutting cylinder, substantially as described.
