Improvements in Machines for Printing Calico and other Fabrics on
Both Sides.
I, JOSEPH WHITWORTH HULSE, of The Regent Iron Works, Salford in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
In a machine for printing calico and other fabrics on both sides, constructed with
two bowls and two sets of printing rollers, cach bowl together with its printing
rollers may be mounted in a respective independent frame, one frame (with its
bowl and printing rollers) being made movable towards or away from the other as
required by suitable mechanism in such a manner that both sides of the frame and
consequently both ends of the bowl are moved simultaneously and equally.
According to one method this object is effected by two rotatory screws coupled
together so as to rotate simultaneously and operate respectively on the two sides of
the movable frame, which stand on a suitable foundation and are traversed along it
simultaneously by the action of the screws. Other means may be employed for
moving the frame, as for example two stationary screws with two simultaneously
rotating nuts or rack & pinion mechanism. Bolts may be provided for securing the
frame firmly to the foundation in any required position.
When the machine is in operation the two bowls are set close to each other to
keep the material which is being printed from stretching, in its passage from one
bowl to the other, sufficiently to prevent the maintenance of accurate register in
the printing. When it is required to wrap and adjust the blankets and greys on
the bowls the movable bowl is separated from the other by the screws or other
means to provide room for this to be done.
If desired both frames with their bowls & printing rollers may be made movable
in the manner described.
The present improvements for moving both ends of a bowl simultaneously and
equally are applicable also when both bowls of a machine are carried on one and
the same frame. In this case the screws for moving the ends of the bowl in their
slides in the frame are coupled together by suitable mechanism for causing them to
rotate simultaneously.
Hitherto for moving the bowls towards or away from each other movement has
been communicated to each end of the bowls independently, thus rendering it
troublesome to reset the axes of the bowls in correct line after the bowls have
been moved apart, for wrapping or adjusting the blankets and greys or any other
purpose.

Improvements in Machines for Printing Calico and other Fabrics on
Both Sides.
1, JOSEPH WHITWORTH HULSE, of The Regent Iron Works, Salford, in the
County of Lancaster, Engineer, 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
In a machine for printing calico and other fabrics on both sides constructed with
two bowls and two sets of printing rollers, each bowl together with its printing

page_text: rollers is according to this invention mounted in a frame independent of that
carrying the other bowl and set of printing rollers, and one frame, with its bowl
and printing rollers is made movable towards or away from the other as required
by suitable mechanism in such a manner that both sides of the frame, and conse
quently both ends of the bowl, are moved simultaneously and equally.
In the accompanying drawings,
Figs. 1 and 2 are respectively a side elevation and a plan of so much of a machine
for printing calico and other fabrics on both sides as is necessary to illustrate the
nature of this invention.
1 is one of the bowls and 2 the corresponding set of printing rollers, these being
mounted in the ordinary or any approved manner in the frame 3 the side members
of which are stayed by one or more rods 4. 5 is the other bowl and 6 the corre-
sponding set of printing rollers therefor, these being mounted in a frame 7 similar
to but independent of the frame 3. Both sets of printing rollers are omitted in
Fig. 2 for the sake of simplicity. Both frames 3 and 7 are mounted upon connected
base plates 8 common to them and by the use of which the construction and
erection of the machine is facilitated. The sides of the frame 3 are permanently
fixed to the base plates by bolts and nuts 9. The sides of the frame 7 are provided
on the underside with fillets that enter slots in the base plates, and are adjustably
fixed to such base plates so that they can be caused to slide end ways thereon, by
headed bolts that pass through the frames and into the slots in the base plate
and are fixed by nuts 10. 11 is a rod with T shaped ends that serves to securely
connect and brace the adjacent upper portions of the frames 3 and 7 together when
the machine is set for work, each end of this rod being formed with a slot 11* to
permit, after loosening the corresponding nut 11b, of any desired endways adjust-
ment of the frame 7.
As will be obvious various arrangements of mechanism can be employed for
moving the frame 7 towards and from the frame 3 in such a way that both ends of
the bowl 5 will be moved simultaneously and to an equal extent so that the axis
of such bowl shall always be maintained parallel to the axis of the bowl 1.
In the
example shown a screw 12 is secured by a cotter to the lower outer end of each of
the two sides of the frame 7 and upon each screw is mounted a nut 13 that is
arranged within a bracket 14 on the corresponding base plate 8 so as to be free to
rotate but not to move endways upon the corresponding screw. The periphery of
each nut is formed as a worm wheel with which gears a worm 15, the two worms
being fixed on a common shaft 16 carried in bearings in the said brackets and
provided with one or more hand wheels 17. With this arrangement, upon loosening
the nuts 10 and 11b and rotating the hand wheel or wheels 17, the two screws 12,
together with the sides of the frame 7, may be simultaneously and equally moved
to the required extent in a direction towards or away from the frame 3 according
to the direction in which the hand wheel or wheels 17 is or are rotated, after which
the frame 7 can be securely fixed in its adjusted position by tightening up the
nuts 10 and 11. Thus it will be understood that the axis of the bowl 5 will always
be maintained parallel to that of the bowl 1, and that the printing rollers 6' will
move simultaneously with the corresponding bowl 5.
Instead of constructing each worm wheel as a nut 13 mounted to rotate on a
screw 12 cottered or otherwise fixed to the sides of the frame 7, each of said worm
wheels may be fixed to its screw 12 in which case the said screws will be arranged
to work in correspondingly screw threaded holes formed in the lower outer end
portions of the sides of the frame 7, or in bushes fitted thereto. Or the sides of
the frame 7 may carry a cross shaft fitted with a hand wheel or wheels and with
pinions arranged to gear with racks formed on or carried by the part of the base
plates 8 adjacent to that upon which the frame 7 slides. Or each of the sides of
the frame 7 may be operated by an eccentric fixed upon a cross shaft-fitted with a
hand lever or other suitable device by which it can be turned, each eccentric being
arranged to work in a slot or opening formed in the corresponding side frame and
the arrangement being such that by partly rotating the cross shaft and eccentrics,

page_text: endways movement will be simultaneously imparted to both side frames 7. These
modified constructions will be readily understood without drawings.
When the machine is in operation, the two bowls 1 and 5 are set close to each
other so that the material which is being printed will, during its passage from one
bowl to the other be kept against the bowls and thereby be prevented from
stretching sufficiently to interfere with the maintenance of accurate register in
the printing. When it is required to place the lapping upon the bowls and to
vary the thickness of such lapping to suit different requirements, the frame 7
carrying the movable bowl is moved away from the other frame and bowl in the
manner and by one or other of the means hereinbefore described to provide room
for this to be done.
If desired each of the frames 3 and 7 with their bowls and printing rollers may
be made movable in the manner described.
In the example shown, the axes of the two bowls are arranged in the same
horizontal plane, but it will be obvious that my invention is equally applicable to
machines of the kind herein referred to in which the axes are in different horizontal
planes.
I am aware that it has heretofore been proposed to move one bowl of a machine
constructed with two bowls and two sets of printing rollers; towards and from the
other bowl by simultaneously adjusting the two bearings carrying the adjustable
bowl in the frame in which both bowls are mounted, but with such an arrangement
it is necessary to also radially adjust each of the printing rollers of the set corre-
sponding to such bowl to adapt them to the new position of the bowl and this
requires considerable skill and time to properly effect. By my invention this
disadvantage is wholly obviated as the adjustable bowl is not moved in a radial
direction relatively to the corresponding set of printing rollers.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A machine for printing calico and other fabrics on both sides constructed with
two bowls and two sets of printing rollers, each bowl and its set of printing rollers
being mounted in a frame separate from that carrying the other bowl and set of
printing rollers and one or each of said frames being provided with mechanism
whereby it can be moved endways towards or away from the other frame, the
arrangement being such that both sides of the adjustable frame or frames and
consequently both ends of the bowl carried thereby will be moved simultaneously
and to an equal extent together with the corresponding set of printing rollers
substantially as herein described for the purpose specified.
2. My improved machine for printing calico and other fabrics on both sides
constructed with two independent frames for the sets of bowls and printing rollers,
the said frames being mounted on a base plate or plates common to them and one
of them being provided with mechanism for moving it to and from the other
substantially in the manner described and shown in the drawings annexed.
Dated this 4th day of July 1893.
