Improvements in or applicable to the Manufacture of Linoleum
and like Floor Cloths.
I, THOMAS MITCHELL, of Albert Works, Waterfoot, near Manchester, and
Noble Street, in the County of London, Manufacturer, do hereby declare the
nature of the said invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
The object of this invention is to obtain, in the manner hereinafter referred to,
variously colored stripe-patterned linoleum or like floor-cloths in which the pattern
will be continuous through the substance of the linoleum or like material, and will
consequently be indelible and not liable to partial or complete obliteration under
varying wear to which surface-printed linoleum and like floor-coverings are
necessarily subject.
In carrying out the invention, the linoleum or like material is prepared in a plastic
condition in a usual manner, but in such varying colors and relative quantities as
may be required to produce the intended stripe-pattern and desired quantity of
floor cloth, and the patterning of the floor-cloth is effected simultaneously with the
manufacture thereof substantially in the manner and by the means hereinafter
referred to.
On the accompanying drawings; Fig. 1, represents, in sectional elevation, a.
linoleum calendering apparatus or rolling mill adapted with the striping apparatus;
Fig. 2, represents a front elevation thereof; and Fig. 3, represents a modification.
4, represents side standards supporting the usual heated calender rolls 5,
by which the dough-like linoleumi or like material is rolled down into the
required thickness and onto the canvas backing 6, the necessary pressure being
applied, and the backing being supported by an under roller 7, in a usual manner.
8, represents a roller over which the backing is passed from the roller 7, and
9, represents a similarly disposed roller under which the backing is passed from the
roller 8, so as to be guided in such a manner as to partly encircle and be supported
by the lower calendering roll 5. Or, the canvas backing may pass directly from
the roller 7, to the roll 5, (as indicated by the dotted lines) so as to be supported
thereby and move therewith.
10, represents framings which may be bolted to the usual standards 4, and
connected by transverse bearers 11, adapted to support a rigid bed plate 12,
which extends, in the direction of its length, the full length of the calender rolls,
and in the direction of its width, from closely adjacent to the lower calender-roll
to as far forward (that is, towards the attendant standing at r, and feeding the
dough-like linoleum onto the bed-plate 12,) as may be required.
The bed-plate is situated at an elevation sufficiently below the passage between
the rolls 5, to leave exposed a sufficient portion of the lower calender roll covered
by the canvas to ensure a continuous drawing in of the linoleum material by
the feeding motion of the calender rolls upon the backing.
The bed-plate is also formed or provided with a series of any required number
of vertical division plates 13, which may be set at any required equal distances, or
at various distances, apart, according to the widths or varied widths of the stripes of
the pattern required to be produced, and such plates may be flanged and project
through slots in and be rivetted or otherwise secured to the bed-plate in any suitable
manner, their upper parts being, if required, also supported against any liability of
lateral displacement due to the action of the calender rolls pressing the excess of
linoleum material backward in the act of rolling the material used onto and into
the fabric of the backing, by transverse gauge bars 14, dropping thereonto or by
screwed rods 15, passed through a series of holes in alignment formed in the division

page_text: plates 13, and adapted with set nuts 16; for supporting each such plate 13, on each
side.
The forward ends of the division plates 13, are accurately curved to the contour
of the calender rolls, and extend as far as possible into the passage or gateway
between such rolls, truly fitting and directly bearing against the revolving surface
of the upper roll and against the canvas supported by the lower roll and so
separating the differently colored adjacent strips of linoleum material until the
moment that such material is drawn by the canvas backing between such rolls,
which simultaneously compress the adjacent strips of linoleum material onto and
into the fabric of the backing, consolidating the edges of such strips and rendering
the material homogeneous throughout, so that the canvas and linoleum material
issue from the rolls as a stripe-patterned floor-cloth or the like, in which the
pattern is continuous through the substance of the linoleum and is produced
simultaneously with the manufacture of the floor-cloth.
The rolls 5, instead of being arranged in a vertical plane, may be arranged in a
horizontal plane, in which event the partitions 13, would extend between the
opposite side plates 12, (vide Fig. 3) so that such plates 12, and partitions 13, would
constitute a vertically disposed hopper.
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
1 claim is
1. The manufacture of a variously colored stripe-patterned linoleum or like
floor-cloth with the pattern continuous through the substance of the linoleum
material, by causing differently colored adjacent strips of linoleum material to
be separated and guided to calendering rolls by a partitioned frame, fitting against
and extending between such rolls, and to be drawn between the same by the feeding
movement of the canvas backing, onto and into the fabric of which such adjacent
strips are simultaneously compressed, so that the backing and linoleum material
issue from the rolls as a stripe-patterned floor-cloth or the like in which the pattern
is continuous through the substance of the linoleum or like material and wherein the
patterning is effected simultaneously with the manufacture of the floor-cloth, as set.
forth.
2. The combination with calendering apparatus for manufacturing linoleum or
like floor-cloths, of a partitioned bed-plate situated below the passage between the
calendering rolls and fitting closely adjacent to the lower roll, the partitions of the
bed plate being adapted to the contour of and to fit against and extend between
the rolls so as to enable the canvas backing to continuously feed adjacent strips of
linoleum material between the calendering rolls, as set forth.
3. The combination in apparatus for manufacturing linoleum or like floor-cloths,
of calendering rolls arranged in a horizontal plane, with a partitioned hopper the
partitions of which are adapted to the contour of and fit against and extend between
the rolls, so as to guide adjacent strips of differently colored linoleum material on to
a canvas backing by which the same are continuously fed between the calendering
rolls, as set forth.
