PROVISIONAL SPECIFICATION.
Improvements in the Construction of Machines for Printing Calico
and other Woven Fabrics on Both Sides.
I WILLIAM BUCKLEY of 53 George Street Manchester in the County of
Lancaster Calico Printer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of that class of calico printing
machines which are employed for printing identical patterns upon both sides of
the fabric, the object of the invention being to ensure the perfectly accurate
registering" of the two patterns.
65
These machines are usually constructed with two large cylinders in combination
with two sets of smaller printing rollers or cylinders, the large cylinders being
covered with an endless blanket or felt and forming a bed against which the
smaller or printing rollers act. The small rollers are all made adjustable in a radial
direction to and from the surface of the large or bed rollers and the latter are
made adjustable only in a vertical direction.
These large rollers or cylinders being first covered with a wrapping of canvas or
other preparation and then with the endless felt or blanket it is necessary to mount
them a few inches apart in order to allow of room for access to arrange the
wrapping and blanket from time to time and it has been found in practice that
the calico or other woven fabric in passing this space from one large cylinder to the
other was liable occasionally to slight displacement thereby destroying the perfect
accuracy of the "register" until readjusted, which caused delay and inconvenience,
as well as occasional loss from imperfect goods.
The object of my invention is to remove or minimise this defect which I propose
to effect by so constructing the machine that the large cylinders can when required,
be moved to such a distance asunder as will allow of the ready placing and adjust-
inent of the wrapping and the blanket or felt, and that when the machine is in
action, the surface of the two felts or blankets shall almost touch each other, and
therefore there is very little, if any possibility of the calico or fabric becoming
displaced in passing from one cylinder to the other and so losing "register."
For this purpose instead. of arranging the adjustable sliding bearings and
adjusting screw of the two large cylinders in a vertical position as hitherto
invariably practised I arrange them diagonally in opposite directions so that they
cau not only be raised and lowered as usual but that the same adjustment will also
bring them nearer together or further apart as may be required.
The smaller or printing rollers will be adjustable in a radial direction as usual.

Improvements in the Construction of Machines for Printing Calico
and other Woven Fabrics on Both Sides.
I WILLIAM BUCKLEY of 53 George Street Manchester in the County of
Lancaster, Calico Printer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to the construction of that class of calico printing

page_text: machines which are employed for printing identical patterns upon both sides of
the fabric, the object of the invention being to ensure the perfectly accurate
"registering of the two patterns.
These machines are usually constructed with two large cylinders: in combination
with two sets of smaller printing rollers or cylinders, the large cylinders being
covered with an endless blanket or felt and forming a bed against which the
smaller or printing rollers act. The small rollers are all made adjustable in a
radial direction to and from the surface of the large or bed rollers and the latter
are made adjustable only in a vertical direction.
These large rollers er cylinders being first covered with a wrapping of canvas or
other preparation and then with the endless felt or blanket it is necessary to mount
them a few inches apart in order to allow of room for access to arrange the
wrapping and blanket from time to time and it has been found in practice that the
calico or other woven fabric in passing this space from one large cylinder to
the other was liable occasionally to slight displacement thereby destroying the
perfect accuracy of the "register" until re-adjusted, which caused delay and
inconvenience, as well as occasional loss from imperfect goods.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the
drawing hereunto annexed which represents an elevation of so much of a calico
printing machine as is necessary to illustrate my invention.
The object of my invention is to remove or minimise this defect which I propose
to effect by so constructing the machine, as illustrated by the drawings, that the
large cylinders a, a can when required, be moved to such a distance asunder as will
allow of the ready placing and adjustment of the wrapping and the blanket or felt
and that when the machine is in action the surface of the two felts or blankets shall
almost touch each other and therefore there is very little, if any, possibility of the
calico or fabric becoming displaced in passing from one cylinder to the other, and
so losing "register."
For this purpose instead of arranging the adjustable sliding bearings and
adjusting screwe of the two large cylinders a a in a vertical position as hitherto
invariably practised I arrange them diagonally in opposite directions as shown, so
that they can not only be raised and lowered as usual but that the same adjustment.
will also bring them nearer together or further apart as may be required.
The smaller or printing rollers & will be adjustable in a radial direction as
usual.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is
In machines for printing calico and other woven fabrics on both sides the
construction and arrangement of the frame of the calico printing machine so
that the sliding bearings of the main cylinders can be adjusted in opposite
diagonal directions substantially in the manner and for the purpose hereinbefore
set forth and illustrated by the drawings annexed.
