PROVISIONAL SPECIFICATION:
Improvements. in Apparatus for Manufacturing Mosaic Floor Cloth.
I, FREDERICK WALTON of No. 114 Holborn in the City of London, Manu-
facturer do hereby declare the nature of this invention to be as follows:
:
In my previous Specification No. 16043 of 1890 I described apparatus for
manufacturing mosaic floor cloth, in which apparatus sheets of plastic material of
various colours were subjected to the action of suitable cutting rollers by which
pieces of them were cut out to pattern; these pieces were placed upon a backing
and carried onwards by a cylinder to have pieces of other colours placed beside
them on the backing, and finally all the pieces were by pressure made to adhere
together and to the backing.
My present invention relates to certain adjuncts to this apparatus for preparing
the sheets of coloured material and for dealing with the parts of the sheets from
which the mosaic pieces are cut. I provide for preparing the coloured sheets,
as many sets of rolls as there are colours, one set for each colour, of the
following description. The material is passed first between a pair of differentially
speeded hot rollers one of them grooved, so that the material issues as a number of
parallel cords. These cords are passed through another pair of rollers from which
a sheet issues and becomes corrugated by crowding into a space leading to a third
pair of rollers, all surplus of material thus crowded being removed by a scraping
roller. From the third pair of rollers the continuous sheet issues and is led over a
measuring roller and thence by suitable guide rollers to the cutting roller of the
inlaying machine. This machine is substantially the same as that described in my
previous Specification above referred to, and operates in substantially the same
manner. I have however introduced a modification at each of the cutting rollers
which is of the following kind. The knives of the cutting roller necessarily divide
the sheet on which they act into two portions, one portion consisting of the pieces
which are to form parts of the mosaic pattern, and the other pieces which do not go
to the pattern. The pattern pieces are extruded from the cutting roller by the
action of a cam as described in my previous Specification, but. before that is. done
the other pieces are, according to my present invention, lifted out of the recesses of
the cutting roller by means of a revolving roller having on it pins which penetrate
these pieces. After being thus lifted out of the cutting roller they are wiped off
the pinned roller and are conveyed back to the set of rolls from which the sheet
came, to be worked again into sheet along with fresh material.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Manufacturing Mosaic Floor Cloth.
I, FREDERICK WALTON, of No. 114 Holborn, in the City of London, Manu-
facturer, do hereby declare the nature of this invention and in what manner the
Bame is to be performed to be particularly described and ascertained in and
by the following statement :-
In my previous Specification No. 16043 of 1890 I described apparatus for
manufacturing mosaic floor cloth; in which apparatus sheets of plastic material of

page_text: various colours were subjected to the action of suitable cutting rollers by which pieces
of them were cut out to pattern; these pieces were placed upon a backing and carried
onwards by a cylinder to have pieces of other colours placed beside them on the
backing, and finally all the pieces were by pressure made to adhere together and to
the backing.
My present invention relates to certain adjuncts to this apparatus, for preparing
the sheets of coloured material and for dealing with the parts of the sheets from
which the mosaic pieces are cut. I provide for preparing the coloured sheets, as
many sets of rolls as there are colours, one for each colour, constructed as shown
in section in Fig. 1 and in plan in Fig. 2 of the accompanying drawings. The
material is passed first between a pair of differentially speeded hot rollers A, B,
one of them A grooved, so that the material issues as a number of parallel cords.
These cords are passed through another pair of rollers C_D, from which a sheet
issues and becomes corrugated by crowding into a space E leading to a third pair
of rollers, D being one of these and F the other, all surplus of material thus
crowded into the space E being removed by a rapidly revolving scraping roller G.
From the third pair of rollers D F, the continuous sheet cleared from D by a
reciprocating knife K worked from a cam L, issues, and is led over a roller H and
thence by suitable guide rollers, of which I is one, to the cutting roller of the
inlaying machine. This machine is substantially the same as that described in my
previous Specification above referred to, and operates in substantially the same
manner. I have however introduced a modification at each of the cutting rollers
as shewn in end view by Fig. 3. The knives of the cutting roller M which revolve
under the pressing roller N necessarily divide the sheet on which they act into two
portions, one portion consisting of the pieces which are to form parts of the mosaic
pattern, and the other pieces which do not go to the pattern. The pattern pieces are
extruded at O from the cutting roller M by the action of a cam as described in my
previous Specification, but, before that is done, the other pieces are, according to
my present invention, lifted out of the recesses of the cutting roller by means of a
roller P which is free to revolve and has on it pins arranged on it so as to penetrate
and pick out these pieces. After being thus picked out of the cutting roller M
they fall or are wiped off the pinned roller P, and are conveyed back to the set of
rolls from which the sheet came to be worked again into sheet, along with fresh
material.
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. Apparatus substantially as described with reference to Figs. 1 and 2 for
preparing coloured sheets of floor cloth material.
2. In combination with the pressing and cutting rollers employed in mosaic floor
cloth apparatus, a pinned roller for picking out from the cutting rollers the piéces
not required for pattern.
