Improvements in Printing Paper, Paper-hangings, Calicoes, other
Woven Fabrics, Warps, and Oil-cloths.
WO JOHN WALKER and HARRY CARVER both of Whit Lane Works Orchard Street
Pendleton in the County of Lancaster Manufacturers of Paper-hangings do hereby
declare the nature of this invention to be as follows:-
Our invention relates to printing paper, paper-hangings calicoes, other woven
fabrics, warps and oil-cloths by means of rollers in which the pattern or design is
"cut," engraved, etched "milled" or otherwise produced.
Hitherto when printing paper, paper-hangings calicoes, other woven fabrics warps
and oil-cloth by means of "engraved" rollers metallic "doctors" have hitherto been
employed in conjunction with such rollers, the said "doctors" being used either to
keep the surfaces of the "engraved rollers" free from "colour" or pigment or other
material or for regulating the quantity of "colour" pigment or other material supplied
to the said "engraved rollers" and such "doctors" have been a source of great
injury to the "engraved rollers" and consequently to the "pattern or design" printed
by such "engraved rollers."
Our invention consists in arrangements by which we are enabled to employ rollers
in which the "pattern" or "design" is "cut," engraved, etched, “milled,” or otherwise
produced, without employing in conjunction with such rollers metallic or other
"doctors."
"
For convenience we shall hereinafter refer to each of the rollers in which the
pattern" or design "is "cut," engraved, etched, "milled," or otherwise produced
as the "engraved roller."
In carrying our invention into effect we instead of supplying the "colour,"
pigment or other material with which the printing is to be done to the lines
cut," engraved, etched, "milled" or otherwise produced upon the " engraved
rollers"
we supply such "colour," pigment or other material to the surfaces only
of the "engraved rollers" so as to leave the lines "cut," engraved "milled" or
otherwise formed in the said rollers free from "colour," pigment or other material.-

We employ as many "engraved rollers
as may be necessary or desirable for
printing the "pattern" or design" upon the paper, paper-hangings calico or other
woven fabric or warp, or oil-cloth being printed and supply the "colour," pigment or
other material to each of such "
engraved rollers in the manner previously
described.
By means of our invention we are enabled to obtain upon paper, paper-hangings,
calicoes and other woven fabrics and warps and oil-cloths a finer and clearer
impression from an "engraved roller" than has hitherto been possible.

We JOHN WALKER and HARRY CARVER both of Whit Lane Works, Orchard Street,
Pendleton in the County of Lancaster Manufacturers of Paper-hangings 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 :-
Our invention relates to printing paper, paper-hangings, calicoes, other woven
fabrics, warps and oil-cloths by means of rollers in which the pattern or design is
'cut," engraved, etched," milled" or otherwise produced.
"
Hitherto when printing paper, paper-hangings, calicoes, other woven fabrics, warps
and oil-cloth by means of engraved rollers, metallic "doctors" have been employed in
conjunction with such rollers the said "doctors" being used either to keep the
surfaces of the "engraved rollers" free from "colour" or pigment or other material
or for regulating the quantity of "colour," pigment or other material supplied to the
said "engraved rollers" and such "doctors" have been a source of great injury to the
"engraved rollers" and consequently to the "pattern or "design" printed by such
66 engraved rollers."

"
Our invention consists in arrangements by which we are enabled to employ rollers
in which the " pattern or "design" is "cut," engraved, etched, "milled," or
otherwise produced without employing in conjunction with such rollers metallic or
other doctors."
For convenience we shall hereinafter refer to each of the rollers in which the
pattern or design" is "cut," engraved, etched, "milled," or otherwise produced
as the "engraved roller."
In carrying our invention into effect instead of supplying the "colour," pigment or
other material with which the printing is to be done to the lines "cut," engraved,
etched, "milled" or otherwise produced upon the "engraved rollers we supply
colour pigment or other material to the surfaces only of the " engraved
rollers so as to leave the lines "cut," engraved, etched, "milled" or otherwise formed
in the said rollers free from "colour" pigment or other material.

We supply "colour" or pigment or other material to each "engraved roller" by
means of a box or trough. In this box or trough we place a roller formed of wood,
inetal or other suitable material, the surface of which dips into the colour" or
pigment or other material contained in the box or trough. In contact with the
roller in the box or trough before mentioned is or are a carrying roller or carrying
rollers. We impart rotary motion to the roller in the box or trough and to the roller
or rollers in contact with such roller, by means of suitable toothed wheels which
receive motion from the wheel by means of which the "engraved roller" is rotated or
in any other suitable manner. We regulate the quantity of "colour," pigment or
other material transferred to the carrying roller or carrying rollers by the roller in
the trough or box by means of screws by which the said rollers may be caused to be

page_text: ог
pressed together as may be necessary or desirable. In contact with the carrying
roller or carrying rollers we employ other rollers which receive "colour
pigment or other material from the carrying roller or carrying rollers and transfer it
to the "engraved roller." The rollers in contact with the "engraved roller" and the
carrying roller or carrying rollers we form of or cover with india-rubber, leather or
other elastic material or composition. We mount the axles of the rollers above
mentioned in bearings provided with screws or other appliances by means of which
the said rollers may be pressed more or less against the roller or rollers with which
they are in contact. The axles of the rollers in contact with the "engraved roller"
we mount in links so as to enable such rollers to be readily removed for cleaning
or other purposes.
By means of the arrangements above described we are enabled to impart to the
surface of the "engraved roller" an even film of "colour," pigment or other material
to be transferred from the "engraved roller" to the paper, paper hangings, calico
or other woven fabric or warp or oil-cloth being printed.
We employ as many,
"
engraved rollers" as may be necessary or desirable for printing the "pattern
or design" upon the paper, paper-hangings, calico or other woven fabric or warp
or oil-cloth being printed and supply the "colour," pigment or other material to
each of such "engraved rollers" in the manner previously described.
By means of our invention we are enabled to obtain upon paper, paper hangings,
calicoes and other woven fabrics and warps and oil-cloths a finer and clearer
impression of an "engraved roller" than has hitherto been possible.
Fig. 1 of the accompanying drawing is a side elevation of so much of a printing
machine as is requisite to illustrate our invention. The machine shewn in Fig. 1 of
the drawing is a machine adapted for printing six "colours" and is similar in general
construction to machines ordinarily employed for printing paper, paper hangings,
calicoes and other woven fabrics, warps and oil-cloth.
In the said drawing we show our invention as applied to two of the rollers a. a.
of the printing machine but when necessary our invention may be applied to any
or all of the rollers employed in such machine. As the apparatus applied to each
of the rollers a. a. is similar to that applied to the other of such rollers we shall
describe only one of such apparatus and affix to corresponding parts in both of
such apparatus the same letters of reference.
b is a box or trough secured in any convenient and suitable manner to the
side-framings c of the machine, only one of which side-framings c is shown in the
drawing. In the box or trough we place a roller d formed of wood, metal or
other material the surface of which roller d dips into the colour or pigment or
other material contained in the box or trough b. In contact with the roller d is
a carrying roller e the surface of which we form of or cover with india-rubber,
leather or other elastic material or composition. In contact with the carrying
roller we place rollers f. f which we form of or cover with india-rubber, leather
or other elastic material or composition. The circumferences of the rollers f, fare
in contact with the roller e and the "engraved roller" a. Fast upon the axle of
the roller e we mount a toothed wheel the teeth of which gear into the teeth of
a wheel carried by and capable of being rotated on a stud k secured to one of
the framings c of the machine. The teeth of the wheel ; gear into the teeth of a
wheel mounted fast upon the axle of the "engraved roller" a the teeth of which
wheel gear into the teeth of the wheel m by means of which rotary motion is
communicated to the engraved rollers a in the ordinary manner. The teeth of the
wheel gear into the teeth of a wheel n fast upon the axle of the roller d. We
mount each end of the axle f of the roller fin a link o one end of which is
jointed to a nut p. capable of being moved by means of a screw y upon guides r
secured to one of the side-framings c. We mount each end of the axle of the
roller fin a links one end of which is jointed to a nut t capable of being
moved by means of a screw u upon guides secured to one of the side framings c
of the machine. w is a roller formed of wood, metal or other suitable material the
surface of which is in contact with the surface of the roller d. The ends of the

page_text: axles d', e¹, a¹ of the rollers d, e, a respectively, are respectively supported by
steps which may be moved each upon one of the framings c of the machine. The
wheels h, j, l, m, n and stud k are indicated in the diagram Fig. 2.

C
When the roller d is caused to rotate such roller d will transfer "colour,"
pigment or other material from the box or trough to the roller e the amount of
colour," pigment or other material transferred to the roller e being regulated by
means of the roller to and screws c. The colour," pigment or other material
transferred to the roller e is transferred to the rollers f, f¹ which rollers f, f¹
transfer the "colour," pigment or other material to the surface of the "engraved
roller"
a in an even film of "colour," pigment or other material to be transferred
from the surface of the "engraved roller' a to the paper, paper-hanging, calico
or other woven fabric or warp or oil-cloth which is passed through the machine
between the cylinder y and the " engraved roller"
We form the pattern or "
design" upon the engraved roller by cutting,
engraving, etching or milling" or in any other suitable manner and we furnish
"colour," pigment or other material to the surface only of such engraved roller
and not to the lines or indentations formed in such "engraved roller." Fig 3 is
a diagram illustrating a cross section of the "engraved roller" a. In Fig. 3 A
are the lines or indentations formed in the " engraved roller" a. We apply the
colour," pigment or other material to the surface of the "engraved roller as
indicated by the lines B and so that the lines or indentations A formed in the
"engraved roller" are left free from "colour," pigment or other material.

Although in the accompanying drawing a printing machine is shown in which
our invention is applied to two rollers, one "engraved roller" or as many
engraved rollers as may be necessary or desirable for printing the pattern or
design" upon the paper, paper-hanging, calico or other woven fabric or warp
or oil cloth being printed may be employed and to such "engraved roller" or to
each of such "engraved rollers our invention may be applied.
"
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
"
"
In a machine for printing paper, paper-hangings, calicoes, other woven fabrics,
warps and oil-cloths by means of rollers the herein before described arrangements
by which we are enabled to employ rollers in which the "pattern" or
"design
is "cut" engraved, etched, "milled or otherwise produced without employing in
conjunction with such rollers, metallic or other "doctors," which arrangements
consist in a roller such as d, roller such as w, roller such as e, and rollers such
as fand fall constructed, arranged and operating in conjunction with each other
substantially in the manner and for the purposes hereinbefore described in reference
to and indicated in and by the accompanying drawing.
