PROVISIONAL SPECIFICATION.
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 this invention to be as follows:-
This invention relates to a development of the invention described in the
Specification of Letters Patent No. 3447 granted to me on the 25th day of
Feb. 1891.
The object of the aforesaid invention was to obtain in the manner and by the
means described in such Specification, variously colored stripe-patterned linoleum
or like floor cloths, in which the pattern is continuous through the substance of the
linoleum or like material, and is consequently indelible and not liable to partial
or complete obliteration under varying wear, to which surface-printed and like
floor coverings are necessarily subject.
In carrying out the aforesaid 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
referred to in said Specification.
The object of the present invention is to obtain a like result, a variously colored
stripe-patterned linoleum or like floor-cloth in which the pattern is continuous
through the linoleum or like material, and in which the patterning of the floor-
cloth is effected simultaneously with the manufacture thereof, substantially in the
manner aforesaid, but by the improved means hereinafter referred to.
I will hereinafter describe the improved striping mechanism as applied to a
calendering machine in which the calender rolls are both arranged in the same.
longitudinal plane.
On the side frames of the machine, vertically above the gateway below the
calenders, and at a suitable distance above the same, I bolt or otherwise suitably
secure two cast iron or other suitable heads, exactly opposite each other. The
said heads are bored with holes, or may be bored and fitted with caps, adapted to
receive two wrought iron or other suitable turned spindles, which are fitted
accurately to said heads and are secured therein by set-nuts or otherwise.
The spindles are horizontally disposed, parallel with each other and with the
axes of the calender rolls, and at a sufficient distance apart to ensure rigidity to
the parts they support, and a sufficiency of space to permit of the feeding of the
linoleum or like material between them.
:
The spindles support a series of any required number of cast iron or other
suitable adjustable heads; each of which is bored with holes easily but truly fitting
said spindles,-
-so as to ensure parallelism of movement and rigidity of support of
said heads,--and is adapted with set nuts or the like by means of which the same can be
rigidly secured in any desired positions along the spindles relatively to each other,"
50 as to vary, as required, the relative widths of the adjacent stripes.
Each of said adjustable heads is formed with a depending part approximating in
contour to that of the opposing calender rolls, and to each of such depending parts
is fitted an adjustable division-plate the edges of which are turned exactly to the
contour of said opposing calender rolls, against which they truly fit, and extend as;
far as possible into the passage or gateway between such rolls. The division plates
are secured to said depending parts of the adjustable heads by. bolts and nuts

page_text: which engage with slots formed in said depending parts which permit of any
required vertical adjustment.
By the aforesaid means, I obtain an absolutely true fitting of the division plates
against the calender rolls, together with the rigidity necessary to prevent any
lateral displacement of the division plates, whereby evenness in the width of
the adjacent stripes in the product, with parallelism in and trueness of the lines
of the meeting edges thereof, are obtained. I also, by such means, obtain a
greater facility of speedier and more accurate adjustment of the division plates.
To ensure absolute rigidity of the division plates against any liability of being
pressed by the feeding of the linoleum or like material against either of the
calenders, or against the backing partly encircling one thereof and passing down
together with the linoleum or like material through the gateway between the
calender rolls, one or each of said spindles may be made flat-sided or of a
squared or other polygonal formation, the heads into which they fit and in which
they are rigidly held, and the adjustable heads which fit on them being, in such
event, formed with through holes of a corresponding formation.
In adapting said improved means to a calendering machine in which the calender
rolls are both arranged in the same vertical plane, substantially the same mechanism
to that above referred to, would be used, but in such case would be arranged
relatively to the gateway between the rolls so that the feed of the material might
be horizontally towards such gateway, inclined towards the same, or vertically and
gradually curving towards such gateway, as might be most convenient in the
particular machine to which the improved mechanism would be applied.

COMPLETE SPECIFICATION.
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 this invention, 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 a development of the invention described in the
Specification of Letters Patent No. 3447, granted to me on the 25th day of
February 1891.
The object of the aforesaid invention is to obtain in the manner and by the
means described in such Specification, variously coloured stripe-patterned linoleum
or like floor-cloths in which the pattern is continuous through the substance of
the linoleum or like material and is consequently indelible and not liable to partial
or complete obliteration under varying wear to which surface-printed and like floor
coverings are necessarily subject.
In carrying out the aforesaid invention, the linoleum or like material is prepared
in a plastic condition in a usual manner, but in such varying colours 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 referred
to in said Specification.
The object of the present invention is to obtain a like result, a variously
coloured stripe-patterned linoleum or like floor-cloth in which the pattern is
continuous through the linoleum or like material, and in which the patterning of
the floor-cloth is effected simultaneously with the manufacture thereof, substantially
in the manner aforesaid but by the improved means hereinafter referred to.
The accompanying drawings illustrate sufficient of a calendering machine (in:

page_text: which the calender-rolls are both arranged in the same horizontal plane) to illustrate
the present improvements.
Fig. 1, is a partial plan view.
Fig. 2, is a sectional elevation on the plane indicated by the line a, b, Fig. 3,
looking in the direction of the arrow c, without showing the calender-rolls in
section.
Fig. 3, is a sectional elevation on the plane indicated by the line d, e, Fig. 2,
looking in the direction of the arrow f, and
Fig. 4, is a partial elevation of a modification.
On the top of each of the usual side frames 4, of the machine, I bolt, as at 5, or
otherwise secure, permanently or detachably as may be required, a headstock 6,
preferably formed of cast iron, securing the two headstocks on the two opposite
side frames 4, exactly opposite to each other, with their centres coincident with a
vertical plane passing through the gateway between the usual calender-rolls 7, 8.
Each such headstock is bored with two through-holes 9, adapted to locate and
support two guide-rods 10, preferably formed of wrought iron, which are fitted
accurately to the headstocks 6, and are secured in the holes 9, therein, by set-
nuts 11, or otherwise in any suitable manner.
of
The guide-rods 10, are horizontally disposed, parallel with each other and with
the axes of the calender-rolls, and at a sufficient distance apart to ensure rigidity.
to the adjustable heads hereinafter referred to, which they support, and a sufficiency
space to permit of the feeding of the linoleum or like material between them.
The guide-rods 10, mutually support a series of any required number of.
adjustable and reversible heads 12, preferably formed of cast iron, each of which
is bored with two holes 13, easily but truly fitting said guide rods, so as to ensure
parallelism of movement and rigidity of support of said heads 12. Each of said
heads 12, can, by means of set-nuts 14, or the like, be rigidly and rapidly secured
in any desired position relatively to any other of said heads along the guide rods,
so as to vary, as may be required, the distances between them, and the relative
widths of the adjacent stripes of the linoleum fabric to be produced.
Each of the adjustable heads 12, is also formed with a depending flange or web 15,
of sufficient strength and rigidity to prevent any lateral displacement due to the
crowding backwards of the linoleum dough 20, while being calendered into
the backing fabric 21, vide Fig. 3. Each flange or web 15, is shaped approximately
to the contour of the opposing calender rolls, vide Fig. 2. To each of such
depending webs is fitted an adjustable division plate 16, preferably formed of steel,
the edges 17, of which are turned exactly to the contour of said opposing calender
rolls, against which they truly fit, leaving only a sufficient clearance for the
passage of the backing fabric 21, and extend as far as possible into the passage or
gateway between such rolls, vide Fig. 2. Each division plate 16, is secured to
the depending part 15, of its adjustable head 12, by bolts and nuts 18, which
engage with slots 19, formed in said depending part, and permit of any required
vertical adjustment of the plate.
By the aforesaid means, I obtain an absolutely true fitting of the division
plates 16, against the calender-rolls and the backing fabric 21, together with
the rigidity necessary to prevent any lateral displacement of the division plates,
whereby evenness in the widths of the adjacent stripes in the product, with
parallelism in and trueness of the lines of the meeting edges thereof (indicated by
the dotted lines a, in Fig. 1, and 3,) are obtained.
I also, by such means, obtain a greater facility of speedier and more accurate
adjustment, or removal and replacement of the division plates.
Either or both of the guide rods 10, may be made flat-sided or of a squared or
other polygonal formation, the heads 6, into which they fit, and in which they are
rigidly held, and the adjustable heads 12, which fit on them, being in such event,
formed with through-holes 9, 13, respectively of a corresponding formation.
In lieu of the heads 6, 12, being cast entire with through-holes 9, 13, they may
each be made in upper and lower parts (vide Fig. 4,) adapted to fit about the

page_text: rods 10, and to meet in the plane in which the axes of such rods are situated,
the upper part being made as a cap and secured to the lower part by screw-bolts 22,
with the rods 10, between the parts.
In. Fig. 3, the bottom end of the stripe-patterned fabric produced is shown as
turned backwards at y, to show the striped side.
In adapting the improved means to a calendering machine in which the calender-
rolls are both arranged in the same vertical plane, substantially the same mechanism
to that above referred to would be used, but in such case would be arranged
relatively to the gateway between the rolls so that the feed of the material might
be horizontal towards such gateway, or inclined towards the same, or vertical and
gradually curving towards such gateway, as might be most convenient in the
particular machine to which the improved mechanism would be applied.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
The combination with the rolls of a calendering machine between which the
backing for the linoleum material passes, of opposite rigidly located headstocks 6;
two parallel guide rods 10, rigidly supported thereby; and a series of adjustable
reversible heads 12, each provided with means for securing it where desired to be
located on the guide-rods, and with an adjustable and removable division plate 16,
accurately fitting the contour of the opposite calender-rolls with a sufficient
clearance for the backing fabric, as set forth.
Dated this 10th day of June 1892.
