Improvements in Printing Textile and other Fabrics.
We, SAMUEL HOLT SHARP and S. H. SHARP & SONS (Leeds) 1.TD., both of
Grove Works, Claypit Lane, Leeds, in the County of York, Textile Printers, 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 improvements in printing designs or patterns on
textile and other fabrics in two or more colours and has for object to ensure
accurate alignment or registering of the colours comprising such a design or
pattern. For this purpose according thereto the complete pattern is printed in
one printing operation by means of one or more endless stencil plates, strips, or
bands that is formed or each formed with perforations that pass completely
through it and correspond to one colour of the design or pattern, and at one side
or surface with indentations or recesses that extend only partly through it and
correspond to another colour of the pattern or design. The endless stencil plate,
strip or band (hereinafter called a stencil plate) or each such plate thus formed,
is mounted upon suitable rollers and is supplied with colour from suitable ducts
or reservoirs provided upon a machine of suitable construction such as that
hereinafter described.
The accompanying illustrative drawings show a stencil printing machine
embodying this invention, Fig. 1 being a front elevation, Fig. 2 an elevation
of the rear or driving side, Fig. 3 a view of the feeding-in end of the machine
and Fig. 4 a back view of a portion of the machine. Fig. 5 is a rear end view of
the machine and Fig. 6 a plan of a portion thereof hereinafter more particu-
larly referred to. Figs. 7 and 8 show respectively in plan and longitudinal
section, a portion of a metallic stencil printing plate according to this invention.
1 is an endless metallic stencil plate that may be formed of a strip of metal of
suitable length and breadth bent to shape and having its ends brazed or soldered
and the joint afterwards reduced to the thickness of the remainder of the plate;
or be made by the electro deposition of a suitable metal on a cylindrical mandrel
or core. The stencil plate has perforations 2 formed through its thickness, and
indentations or recesses 3 are also formed therein at one side.
The stencil plate 1 is mounted on metal rollers 4 and 5; the roller 4 is mounted
in bearings 6, 6ª in the brackets 7, 8 secured to the main frames 9, 10 of the
machine, and the roller 5 is mounted in bearings 11, 11* in the brackets 12, 13
secured to saddles 14, 15 which can be simultaneously moved on slides 16, 17 by
means of screws 18, 19 revolving in bearings 20, 20" in the ends of the slides 16, 17.
The screws 18, 19 have secured on their ends 21, 21* bevel gear wheels 22, 23
which gear with other bevel gear wheels 24, 25 secured to a cross shaft 26
mounted in bearings 27, 27ª on the frames 9, 10. The cross shaft 26 is rotated,
when desired, by the hand wheel 28.
29 is an ink duct mounted on brackets 12, 13, and capable of adjustment
thereon towards and away from the roller 5 by means of screws 30 rotating in

to the brackets 34, 35. The beam 33 is provided with a flexible pressure 36, which
acts on the pressing cylinder 37. This pressing cylinder 37 is mounted on a
shaft 38 which rotates in bearings 39, 39ª vertically adjustable in guides 40, 40
on the main frames 9, 10. The bearings 39, 39 with cylinder 37 are moved
towards and away from the flexible presser 36, by means of eccentrics 41, 41
secured on a shaft 42, mounted in bearings 43, 43°. A worm wheel 44 secured
on the outer projecting end 45 of the shaft 42, receives motion from a worm 46
secured to a vertical shaft 47 mounted in bearings 48, 48 on the bracket 49. 50 is
a hand wheel for rotating the shaft 47.
Below the ink-duct 29 there is mounted in bearings 51, 51" a shaft 52 having
a square part 53 to which is secured a scraper 54. On the outer projecting
ends 55, 55 of the shaft 52 there are secured levers 56, 56 having forked
ends 57, 57, provided with pins 58, 58 on which are hung rods 59, 59. These
rods 59 59 suspend slip weights 60, that furnish the required pressure to the
scraped 54.
a
To the inner side of each bracket 12, 13 there are secured studs 61, 61% on which
are mounted arms 62, 62° the outer ends of which are furnished with bearings 63,
63 for the shaft 64 of a felt covered roller 65. 67 is a pulley secured on the
end 68 of the shaft 64 and driven by a strap 69 from a pulley 70 on the main
driving shaft 71 of the machine. The felt covered roller is moved towards and
away from the stencil sheet 1 by means of screws 72, 72" which are mounted in
Dscillating bearings 73, 73 turning in swivelling nuts 75, 75% secured to the
arms 62, 63. A shaft 77 is mounted in bearings 76, 76 on the brackets 12, 13,
and on the square part 77" thereof is secured, by means of screws, a scraper 78
To one end of the shaft 77 is secured a lever 79, one of its ends forming
nut 79 in which can turn a thumb-screw 80 the end 80% of which bears against
the side of the bracket 12 and so causes the scraper 78 to bear against the
roller 5. Below the scraper 78 is a trough or spout 81 secured to the square
part 82 of the shaft 82" which is carried in bearings 83, 83" and can be angularly
adjusted and kept in position by means of the spring 84 and nut 84 on one
of its ends 84b. 85, 85" are guides in which is placed the cleaning bar 86 covered
at its lower part 86% with felt secured thereto by plates 86, 86° and screws 86d.
The brackets 12, 13 are also provided with bearings 87, 87, in which may be
mounted the shaft of a guide roller when the machine is required to print strips.
88, 88 are guides formed in the brackets 34, 35 in which is placed a cleaning
bar 89 similar to the one above described and which is capable of being set up
to the stencil plate by means of set screws 90, 90%. On the back of the brackets 34,
35 are parallel vee shaped guides 91, 91" in which the slide 92 having bear-
ings 92, 92b can slide. The bearings carry the shaft 93 with its scraper 93"
which is moved by means of a worm wheel 94 on a shaft 93 gearing with a
worm 95 on a shaft 96 which is carried in bearings 97 and is moved by means
of a hand wheel 98.
99, 99 are studs secured to the inner sides of the brackets 7, 8 and on which
are mounted arms 100, 100" provided with bearings 101, 101 102 is a shaft
mounted to rotate in the said bearings and having formed on it the damping
roller 102 covered with felt. The shaft 102 on one of its ends has secured to
it a pulley 103 which receives motion from another pulley on a countershaft.
The arms 100, 100 are capable of adjustment towards and away from the roller 4
by means of screws 104, 104 mounted in swivelling bearings 105, 105 in the
forked ends 106, 106 of the arms 100, 100% and screwing into oscillating nuts 107,
107 on the brackets 7, 8.
108, 108 are bearings in the brackets 7, 8 in which is mounted a shaft 109
having a square part 109ª on which is secured a scraper 109b which is pressed
against the roller 4 by means of a lever 110 having at its end 111, a screw 112
turning in a nut 112, the said screw being arranged to push against the side of
the bracket 7.

page_text: 113, 113 are parallel guides formed in the brackets 7, 8 in which sliding
bushes 114, 114, movable up and down by means of screws 115, 115ª are mounted
and retained in position by the caps 116, 116 117 is a shaft which rotates in
the bushes 114, 114" and on which is secured a brush 118. 119 is a pulley for
driving the shaft 117. In similar parallel guides 120, 120ª formed in the
same brackets, there are mounted similar sliding bushes 121, 121° moved by
screws 122, 122" and retained by caps 123, 123". 124 is a shaft which is mounted
and rotates in the bushes 121, 121ª and to which is secured the wiping or cleaning
roller 124 covered with felt 124b. On one end of the shaft 124 is secured a
driving pulley 125 and on the other end is secured a cam 126 formed on its
periphery with a cam groove between the faces of which there works a fixed
stud 127 carried by an arm 128 secured to the bracket 8.
On the brackets 129, 129 of the blanket extending arms 130, 130° are pro-
vided bearings 131, 131 in which is mounted a shaft 132 with a right and left
handed screw threaded spreading roller 132. 133 is a driving pulley on one
end of the shaft 132 and on the other end thereof is secured a grooved boss 134
for moving the spreading roller 132ª endwise, by means of the lever 135 secured
to the shaft 136 provided with a stud 137 taking into the groove of the said boss;
the shaft 136 extends along the front of the machine and is mounted in a
bearing 138 secured to the main frame 9 of the machine and in a forked bear-

secured to the shaft 136 by means of a sliding key or feather and is used to rock
the shaft in either direction, its movement being limited by stop pieces 141
and 14.1 on the bracket 139.
The shaft 136 is secured between the forked bearing 138" by the lever 135
so that, on the blanket extending bracket 129 being moved to or from the
cylinder 37, the shaft is moved enawise in the bearing 138ª.
The material to be printed is passed over the roller 142 under the tension
roller 143, over the shaft 144, and under and over the tension roller 145, then
over the spreading roller 132ª, which takes out any creases there may be in the
material, the said roller being capable of movement to either side of the machine
so as to enable the material to be placed in the required position. The material
then passes on to the blanket 146 and under the pressure 36 the required pressure
being then put on it by raising the cylinder 37.
ог
The travelling stencil plate 1 on passing the ink duct 29 has its perforations 2
and indentations or recesses 3 which form the pattern to be printed, filled with
one colour of ink or composition and on passing the scraper 54 is relieved of any
surplus ink. The ink in the indentations or recesses 3 is carried forward by
the stencil plate but that which entered the perforations 2 of the said stencil
plate is left on the roller 5 from which it is removed by the scraper 78 and
as it accumulates it drops off into the trough or spout 81, thus leaving
the perforations 2 empty. The inner upper surface of the lower
length of the stencil plate is cleaned of any colour thereon by the revolving
roller 65, and the perforations are again filled with another coloured ink or com-
position supplied from the second ink duct 32. On the stencil plate and material
passing together between the presser 36 and the cylinder 37 and blanket 146, the
ink or composition in both the perforations 2 and recesses 3 is imprinted on the
material which partly enters the said perforations and recesses; the material then
leaves the stencil plate and is carried away as usual. The stencil plate passes
under and around the back roller 4, where it is first damped or wetted with tur-
pentine or other fluid by the revolving felt covered roller 102. then the colour is
removed from the plate by the scraper 109b, the semi-perforations or recesses are
brushed out clean by the revolving brush 118 and finally wiped dry and perfectly
clean by the revolving wiper 124 and following cleaners, whereupon they pass
forward again to the first ink duct 29.
With the arrangement herein before described it will be understood that the
stencil plate can be used for printing two colours, but by dividing the colour reser-

page_text: voirs transversely to the machine into several compartments, or by using several
reservoirs arranged side by side, ink or composition of various colours can be sup-
plied to different parts of the stencil plate across the width thereof.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is: -
1. Printing textile fabrics in colours by means of a stencil plate having perfora-
tions therethrough corresponding in shape to parts of the pattern or design to be
printed in one colour, and indentations or recesses at one side thereof correspond-
ing to other parts of the pattern or design to be printed in a different colour, the
said perforations and indentations or recesses being charged with the respective
colours for transference to the fabric to be printed, substantially as described.
2. In machinery or apparatus for printing textile fabrics in colours, an endless
stencil-plate having perforations therethrough corresponding to parts of the pattern
or design to be printed in one colour, and with indentations or recesses at one side
or surface of the said plate corresponding to other parts of the pattern or design to
be printed in a different colour, means for respectively supplying colour to one
side of the stencil plate, for withdrawing colour from the perforations therein, for
replacing it with a different colour, and for operating and cleaning the said plate,
the arrangement being such that the plate is first charged with one colour sup-
plied at the recessed side thereof and the colour entering the perforations is
alterwards removed therefrom and the perforations are re-charged with a second
colour without interfering with the colour in the indentations or recesses, the two
colours being afterwards simultaneously transferred to the material to be printed,
substantially as described.
3. In a fabric printing machine of the kind herein described, a right and left
hand screw threaded spreading roller provided with means for moving the same
from side to side of the machine, substantially as described for the purpose set
forth.
4. Machinery or apparatus for stencil-printing fabrics in colours, constructed,
arranged and operating substantially as herein above described with reference to
and shown in the accompanying drawings.
