COMPLETE SPECIFICATION.
Improvements in Machines for Printing Fabrics.
I JOHN SHINN, of Roxborough, in the County of Philadelphia, and State of
Pennsylvania, United States of North America, Mechanical Engineer, do hereby
declare the nature of my invention for PRINTING WOVEN FABRICS, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to machines for printing heavy woven fabrics-such as
carpets, rugs, horse-blankets, lap-robes, plush and other pile fabrics, cut or unent;
and it consists in combining with an engraved roll a suction-box, by means of which
suction the air is drawn from the fibers of tlie fabric, and coloring matter drawn
through to print or color the fabric at such places as the engraved print roller shall
place the coloring matter. I attain these objects by the mechanism illustrated in
the accompanying drawings, making a part of this Specification, in which-
Figure 1 is a longitudinal and sectional elevation, showing in section parts of a
machine for printing three colors and constructed according to my invention.
Figure 2 is a cross-section of a print-roller and suction-box, taken on the
line XY, of Fig. 3.
Figure 3 is a longitudinal section of a print-roller, and suction-box, taken on the
line XY, of Fig. 2.
Similar letters refer to similar parts throughout the several views.
A represents the fabric; B3 the engraved print-roll; D the color-box, and a the
"doctor."
These rolls, boxes, and doctors are constructed in the usual manner for fabric-
printing machines.
The print-rollers, color-boxes and doctors are arranged in a suitable frame and
placed, one leading the other, on a horizontal line, as shown in the drawings.
P is a suction-box. This box should be made of brass, and have a series of
ribs VV, (see Figs. 2 and 3).
These ribs should be made of cold-rolled brass, and smooth on the lower edge.
Price 6d.]

page_text: The ends of the suction-box extends over the ends of the engraved print-roll. These
ends should be a good fit, but not air-tight.
From the top of each suction box, is a pipe h, having a stop-cock y.
F is an air-tight box.
G is an exhauster, such as used for pumping air, d, d are carrying-rollers, and
should be "spiked."
The carrying rollers and print rollers are driven by spur-gears from the shafts of
the print-rollers, and the roller to the extreme right drives by a chain belt the
roller above it, and that roller drives the upper one on the left by a chain belt.
R is an endless wire apron, the top part running on rollers S S. This wire apron
and carrying-rollers should be made of brass.
J is a metal box, in which is placed a series of steam pipes p, p.
If these pipes
are to be used for "steaming" the fabric, the pipes will be perforated with numerous
small holes. E E, are drying-cylinders, which are constructed and operated in the
usual manner to dry printed fabrics.
The operations of my improved printing machine is as follows: The cloth to be
printed moves in the direction indicated by the arrows, Fig. 1, as also do the
engravel rollers, as indicated by the arrows on them.
The engraved rollers B will raise coloring-matter in the engraved parts, and as
the color in the engraved parts of the roller gets under the suction-box P the
exhauster G will by the pipe h draw or suck the air from the fabric under the
box P.
The ribs V V, prevent the fabric from rising from the roller B, and as the air is
drawn from the fibers of the fabric, the coloring-matter will take the place of the
air and be absorbed by the capillary attraction of the fibers; the suction on the
box P being regulated by the stop-cock g, in pipe h.
The fabric passes from print-roller to print-roller and receives such number of
colors as there are rollers and the design requires, and any number of colors may
be used, as desired, or a design calls for. After printing, the cloth is carried by
the wire-cloth apron R, over the pipes p, p, and is steamed or dried, as the case may
be. Some colors are made brilliant without steaming.
If pile fabrics are to be printed, I prefer to run the pile face against the face of
the print-roller, and the color will be sucked through to the back, making a print
as deep as the pile and without crushing down the pile, and thereby make an
imperfect print.
It is obvious that my invention may be used to print on thin fabrics, and the
colors be taken from the engraved rollers B, by the affinity the fibers of the fabric
have for the coloring-matter, the suction-box not being required with thin
fabrics.
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
I claim is :-
First In a machine for printing woven fabrics, the combination of an engraved
roll, a suction-box, and a carrying roller d, as shown, described, and for the purpose
specified.
Second-In a machine for printing woven fabrics, the combination of an engraved
roll and a suction-box provided with a series of ribs V, V, and a carrying-roller d,
as shown, described, and for the purpose specified.
Third In a machine for printing woven fabrics, the combination of a color-box,
an engraved roller, and a spiked carrying-roller d, as shown, described, and for the
purpose specified.
