Improvements in or applicable to Machinery for Printing on
Fabrics.
We FRANK DANIEL HADDON of Hill Side, Romiley, in the County of Chester,
Calico Printer, and ALBERT ARTHUR KUENEMANN of 10 Acomb Street,
Greenheys, Manchester, in the County of Lancaster, Textile Designer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide means for cleaning, cooling, and lubri-
cating the surfaces of engraved printing rollers used in such machinery the
invention being more particularly designed for use in such printing machines as
are fitted with a divided color trough for furnishing different colors to various
parts of the same roller, but the invention is also applicable with advantage to
printing machines wherein each engraved roller is supplied only with one color.
For the purposes of our invention we fix on the "lint-doctor-shears" a long
trough, or the shears and lint-doctor may be used as the under side of the trough,
or the trough may be used independently of the "doctor." In this is mounted
(so as to be capable of revolving) a roller of iron or other metal, coated with a
soft pliable material or composition, and so fixed at each end of the trough as to
be partly within the said trough and parallel with the surface thereof, and partly
projecting and in contact with the said engraved roller just above the line of
meeting of the doctor with the engraved surface, so that the said covered or coated
roller will revolve by friction of contact with the engraved printing roller. The
covered roller may be parallel throughout its length so as to touch the printing
roller from end to end, or it may be cut away at parts (especially when used with
a divided color trough) so as only to be in contact with the engraved roller at those
parts where the color furnishing rollers do not touch, or at such other parts as may
be required, so as to clean and cool the whole printing roller or only certain
portions thereof.
The trough is to contain water or other suitable liquid and will be kept full to
such a level that the lower portion of the covered roller will dip therein and
constantly feed such moisture to the surface of the printing roller in contact with
which it revolves; or if preferred the covered roller may revolve above the level
of the water or liquid in the trough and be supplied therewith by means of a small
furnishing roller revolving in the water or liquid and in contact with the soft coated
roller, or in any other convenient manner.
In place of the soft coated roller. above described we may in some cases use a
fixed bar provided with a strip of some soft or spongy material, one edge of which
slightly presses on the surface of the engraved printing roller, and water or liquid
may be supplied to such strip by a revolving roller, or otherwise, so as to damp and
clean the printing roller as it revolves in contact with the strip.
By thus damping and cleaning the printing rollers we believe that we shall be
able to dispense with the "drag-rollers" usually placed between the "nips" when
thick or cloggy coloring matters are employed for printing.

Improvements in or applicable to Machinery for Printing on
Fabrics.
We FRANK DANIEL HADDON, of Hill Side, Romiley, in the County of Chester,
Calico Printer, and ALBERT ARTHUR KUENEMANN, of 10 Acomb Street,
Greenheys, Manchester, in the County of Lancaster, Textile Designer, 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:-
The object of this invention is to provide means for cleaning, cooling, and
lubricating the surfaces of engraved printing rollers used in such machinery, the
invention being more particularly designed for use in such printing machines as
are fitted with a divided color trough or other means for furnishing different colors
to various parts of the same roller. The object of the invention being to prevent
any particles of color from caking upon the engraved roller at those parts where
it is not kept moist by the color furnisher, and from passing beneath the color
doctor and coming into contact with the fabric to be printed and thus spoiling the
same.
Our invention will be readily understood on reference to the accompanying
drawings;
Fig. 1 is a sectional elevation, and Fig. 2 a plan of a part of an engraved roller
furnished from a divided color trough with our moistening apparatus applied
thereto, the color doctor being removed from Fig. 2.
Figs. 3 and 4 illustrate modified forms of the moistener.
a is the engraved roller, 6 the furnisher shewn as a roller, c is the color trough
divided into compartments by the plates c. d is the color doctor, e is the lint
doctor.
We fix on the "lint-doctor-shears" e a long trough e2 and the lint doctor e may
be used as the under side of the trough e. In this is mounted (so as to be capable
of revolving) a roller f of iron or other metal, coated with a soft pliable material
or composition, and so fixed at each end of the trough as to be partly within the
said trough and parallel with the surface thereof, and partly projecting and in
contact with the said engraved roller a just above the line of meeting of the lint
doctor e with the engraved surface, so that the said covered or coated roller f will
revolve by friction of contact with the engraved printing roller. The covered
roller may be parallel throughout its length so as to touch the printing roller from
end to end, so as to moisten and cool the whole printing roller, or it may be cut
away at parts as shewn so as only to be in contact with the engraved roller at
those parts where the color furnishing rollers do not touch, and thus moisten and
cool only the required portions thereof.
The trough is to contain water or other suitable liquid and will be kept full to
such a level that the lower portion of the covered roller will dip therein and
constantly feed such moisture to the surface of the printing roller a in contact with
which it revolves; or if preferred the covered roller may revolve above the level
of the water or liquid in the trough and be supplied therewith by means of a small
furnishing roller revolving in the water or liquid and in contact with the soft
coated roller, or in any other convenient manner; for example the roller may be
supplied at the desired points with liquids by means of a pipe for trough having
suitable perforations therein see Fig. 3.
In place of the soft coated roller above described we may in some cases use a
fixed bar provided with a strip or a series of strips of some soft or spongy
material see Fig. 4, one edge of which slightly presses on the surface of the

page_text: engraved printing roller, and water oil or other liquid may be supplied to such strip
by a revolving roller, or otherwise, so as to damp and cool the printing roller as it
revolves in contact with the strip.
In some parts of the printing machine such strips of cloth may be placed
between the point where the color is furnished and the color doctor d, as shewn
dotted on Fig. 4.
Or the moisture may be applied to the desired parts of the engraved roller by
allowing it to drip in very limited quantities upon such parts or supplying it by
other equivalent means.
The roller
and trough e or the other moistening device may be separate from
the lint doctor and either above or below the same.
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:-
The combination with an engraved roller furnished by separated furnishers with
various colors of means for moistening and cooling those parts of the said engraved
roller not kept moist by the furnishing apparatus, substantially as and for the
purpose herein before set forth.
