Improvements in or relating to Calico Frinting and like Machines.
:―
We, JAMES ALLAN SACKVILLE and JOHN HENRY SWALLOW, both of Royal Oak
Print Works, Pendlebury, near Manchester, in the County of Lancaster, Calico
Printers, do hereby declare the nature of our said invention to be as follows:-
Our said improvements have reference to the invention for which we obtained
Letters Patent No. 796 on the 12th day of January 1897, and consist first, of a
novel arrangement of "
99
squeegee or squeegee holder, secondly-in the com-
bination with said squeegee of end squeegees and means for conveying and
disposing of the surplus color and water, and thirdly, of means for enabling the
improved squeegee, or the squeegee described in our former specification, to move
with the cylinder or bowl each time such bowl is adjusted.

Our said improvements also consist of a novel arrangement of "duplex printing
and cleaning apparatus, for enabling pieces of cloth to be printed on both sides
at one operation, or of enabling pieces of cloth to be first printed with a
and immediately afterwards be "slop padded," or "slop padded" first and then
printed with a discharge" upon the same side, at one run of the machine.
In accordance with the first part of our invention, we employ a squeegee or
squeegee holder, more or less of channel formation. and so arranged as to cause
the rubber or like edge, which lies against the cylinder, to act against the cylinder
after the manner of a turning tool, or, by preference, to lie in such relation to the
cylinder as to cause the bottom of the channel to be slightly lower than such
working edge. This arrangement of "squeegee" maintains a volume of water in
the angle between the squeegee and cylinder, and thereby keeps the edge of the
squeegee "lubricated," whilst it also enables the squeegee to more effectually
remove the color, or any lint or solids on the cylinder, which when removed are
then received by such squeegee, and gravitate to the lowest part of the channel,
instead of tending to lift the squeegee off and pass round the cylinder.
This improved squeegee is, by preference, made in one piece with, or is rigidly
connected to, squeegees which act upon the ends of the cylinder in a similar
manner, and at the junction of which the outlet for the color and water, etc., is
formed, with means for connection to a pipe for allowing it to drain away.
The devices used for supporting and feeding the squeegees against the cylinder
are, by preference, mounted upon the bearing caps of the cylinder axis, or
mounted in such other way as to permit the "
"
squeegee to follow the cylinder
when adjusted in its bearings.
The pipe for spraying the water may either spray it upon the cylinder, or into
the trough of the squeegee, or we may simply keep the trough constantly filled
with water, with means for preventing its overflow.
This improved arrangement of "squeegee" may be used with (or without) the
brush described in our former specification, which may have either ordinary fibre,
bristles, or rubber or like bristles to suit the various conditions of working.
In accordance with the further features of our invention and for effecting what
is known as
duplex" printing, we employ two india-rubber or like covered
66

page_text: cylinders or bowls, also a third cylinder or bowl, acting both as a carrier bowl
and a drying cylinder. To each rubber covered bowl we then apply our washing
or cleaning, or color moistening apparatus. The cloth to be printed first passes
between one of the rubber covered cylinders and its color roller or rollers. It
then passes over the carrier cylinder and between the other rubber covered
cylinder and its color roller or rollers, and then passes out of the machine, printed
on both sides, since the peculiar path of the cloth presents one side of the cloth
to the color rollers of one cylinder, and the other side to the color rollers of the
cylinder, and with the carrier bowl placed as close to the other bowls as possible,
and heated by steam, the operation is successfully carried out.
For the purpose of utilising the existing apparatus for holding the cloth, it (the
cloth) may pass down behind the attendant, beneath the level on which he stands,
and enter the machine beneath the cylinders.
For printing the cloth with a
resist as aforesaid, we again employ two india-
rubber covered bowls and a carrier cylinder with color rollers and cleaning
apparatus for each bowl, but we pass the cloth through the machine in a manner
which causes the same side of the cloth to be printed upon by both sets of color
rollers, and with one set of rollers printing a resist," and the other the "slop
padding" color we permit of the printing in "resist" style at one run of the
machine. This same machine may be used for "slop padding" first, and then
discharging" the color.
66
It is almost needless to add that by such adaptation of our invention in the
aforesaid manner, we entirely dispense with lappings, blankets and back-greys,
besides effecting a great saving in the working of the machine.
In both these modifications the " squeegees or cleaning apparatus are adjust-
able to suit the direction in which the cylinders run, and either the aforesaid
improved trough squeegee or the cleaning apparatus described in our former
specification, (or both), may be employed.
The number and order of the parts, also the arrangement of cylinders, or bowls,
may be modified to suit the purposes of our invention, and in reference to the
cleaning apparatus, the manner in which the water or moistening agent is
imparted to the color, or cylinder, may be varied to suit the exigences of working,
or the various systems, styles or methods of printing.

Improvements in or relating to Calico Printing and like Machines.
We, JAMES ALLAN SACKVILLE and JOHN HENRY SWALLOW, both of Royal Oak
Print Works, Pendlebury, near Manchester, in the County of Lancaster, Calico
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:-
Our said improvements have reference in part to the invention for which we
obtained Letters Patent No. 796 on the 12th day January 1897, and the accom-
panying two sheets of drawings illustrate the several features of our present
invention.

page_text: On Sheet One, Fig. 1 illustrates in diagram a printing machine for printing
fabric on both sides simultaneously, and Fig. 2 illustrates in diagram the same
printing machine, slightly modified, for effecting what is known as
" resist" or
discharge" printing, and both views illustrate the application of our improved
printing bowl cleaning apparatus.
On Sheet Two, Figs. 3 to 6 illustrate in sectional elevation and part plan two
forms of the said cleaning apparatus to an enlarged scale
Referring now to Fig. 1, we employ two printing bowls or cylinders (A), (A¹)
fitted with a sleeve or covering of elastic material (B) of, by preference, ³/ths of
an inch thick, and of a good quality of india-rubber having a hard or semi-solid
character. Such printing bowls are mounted in a suitable framing and driven
by suitable gearing in opposite directions at the same surface speed. (C) and C¹
are the usual engraved pattern printing rollers, supplied with coloring matter
in the ordinary way.
The piece to be printed on both sides passes into the machine from roll (D),
beneath carrier roller (E), below the floor level (F), beneath carrier roller (G),
over carrier roller (H), and around the bowl (A') when it becomes printed upon
by printing roller (C). In leaving bowl (A¹) it may either pass over a steam-
heated carrier drum (J) (as shewn in dotted lines), or directly on to the bowl (A)
where it is printed upon by the printing roller (C) upon the reverse side to that
previously printed upon by roller (C), and after leaving bowl (A) the piece passes
forward and leaves the machine printed upon both sides.
In the case of "discharge," or resist" printing, we employ the same machine,
but introduce the fabric to be printed and pass it through the machine in the
manner shewn in Fig. 2, the printing roller (C) imparting the resist fluid for
resist" printing, and the roller (C) imparting the discharge fluid for "dis-
charge" printing. The bowls in this case rotate in the same direction as each
other, and drum (J) is used.

In each style of printing, i.e. "duplex,"
""resist" or discharge" there are no
lappings," no blankets," no back-greys," and all excess color is allowed to
pass on to the bowl whilst the necessary elastic cushion, heretofore furnished by
the blanketting, is afforded by the thick elastic covering (B).
For removing the excess color allowed as aforesaid to get on to the rubber
covering of the bowls, we employ the cleaning apparatus described in our said
former specification, or the improved cleaning apparatus hereinafter described
and shewn in Figs. 3 and 4, or Figs. 5 and 6 of the drawings.
"
Referring to Figs. 3 and 4, we employ a squeegee holder forming part of,
or formed as a trough (L), and so devised, in relation to the squeegee (M), as to
allow a pool of water to lie in contact with the rubber covering (B) of the printing
bowl, and immediately above the working edge of the squeegee, thereby enabling
particles of lint or fluff to be washed off the cylinder, and the excess coloring
matter to be thoroughly wetted or moistened previous to its removal from the
bowl by squeegee (M), besides keeping the edge of such squeegee constantly
lubricated" and most effective in operation. The said trough-squeegee holder may
be in one piece with, or be connected to, like trough-squeegee holders for keeping
the ends of the bowls clean, as shewn by dotted lines in Fig. 3, and in plan in
Fig. 4, although in the case of bowls with irregular shaped ends, we may require
to discard end squeegees and end squeegee holders, and simply close the ends of
the trough by turning them in, somewhat in the manner shewn in Fig. 6, with
the squeegee also curved off to lie near each end of the bowl, and with its edge
shaped to lie upon the curved surface thereof.
The improved squeegee holder is carried by bracket or arms (N), secured to
the bearing caps of the bowl axle, so that the squeegee may follow the bowl no
matter how the position of the bowl may vary in relation to the machine frame.
Each end of the squeegee holder is provided with a bearing pin (0) which
rests in an adjustable bearing block (D) in the slot (Q) of the arm (N), and
which blocks, under the action of a screw (R) connected to each, are capable of

page_text: being set at various points according to the requirements of the squeegee. To
keep the squeegee in contact with the bowl we provide a strong spring, or a
set screw (R¹).
The squeegee shewn in Figs. 5 and 6 is mounted in the same way and is held
to the bowl by spring (S), or equivalent device. In conjunction with the squeegee,
we use the brush or scrubber (U) which has a to-and-fro movement, also the
spray pipe (T), but for some classes of work we may use the squeegee and pool
of water only.
In each case we may supply water to the space between the squeegee holder
and cylinder by a special inlet pipe, or increase and use the supply of water from
spray pipe (T), with an outlet pipe (V) to take away the overflow or dirty water.
In lieu of the oscillating brush we may use a rotary brush running in an
opposite direction to the bowl, and separate from, or in conjunction with a
cleaning roller, instead of, or in addition to a squeegee, with a trough beneath for
such roller to run in, and the cleaning apparatus may be applied to any part of
the bowl necessary. The brush or scrubber may be composed of india rubber, or
other material not affected by the coloring matter.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
rr
1 In machines for printing fabrics and the like upon both sides simul-
taneously, or for "resist"
or discharge" printing, the use of two bowls, fitted
with a covering of india-rubber, in combination with printing and carrier rollers,
and cleaning apparatus, substantially as set forth and illustrated on the accom-
panying drawings.
2: In apparatus for cleaning printing bowls, a squeegee sustained adjustably
against the bowl by a squeegee holder adapted to allow a pool of water to lie in
contact with the bowl and immediately over the working edge of the squeegee,
substantially as and for the purpose set forth.
3: In apparatus for cleaning printing bowls, a squeegee and squeegee holder
pivotally mounted in adjustable bearing blocks, working in slotted arms carried
by the bearing caps of the bowl axle, and said squeegee fitting the face and ends
of the bowls, or face only, and provided with water supply and overflow pipes,
as set forth.
4: The combination of the said pivotally and adjustably mounted squeegee
and squeegee holders with the scrubber and spray pipe, as and for the purposes
set forth.
