PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Intermitten Printing.
I WILLIAM BUCKLEY of Brookside Print Works, West Leigh in the County
of Lancaster, Calico Printer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to machinery or apparatus employed for printing calico
and other woven fabrics and more especially to such machines as are used for
printing borders or beadings at intervals across the piece as in printing handkerchiefs
scarves and other similar intermittent printing.
The principal features of the invention are
(1) That the apparatus which brings the intermittent printing roller into action
is worked direct from the mandrel of the same ;
(2) That the action for bringing the roller into contact with the work is
instantaneous ;
(3) That the roller is moved out of contact with the work by means of a cam
running the same number of revolutions as the mandrel ;
(4) That the length of interval at which the rollers are moved towards or from
the cylinder is easily regulated.
On the mandrel of the intermittent printing roller I mount a worm which gears
with and drives a worm wheel mounted on a driving shaft. On this shaft is also
keyed a spur wheel driving another spur wheel on a short spindle parallel to the
driving shaft, carried by a fixing on the machine side.
At the other end of this short spindle is a spur pinion gearing with an internal
disc wheel mounted loosely upon the driving shaft. There is also a cam keyed on
the driving shaft and running the same number of revolutions as the mandrel of the
intermittent printing roller.
Round a spindle secured to the block which carries this mandrel is coiled a spiral
spring abutting against the block and having a constant tendency to force the
roller against the main cylinder. This spindle is also provided with a latch which
when in action holds the spring in a state of compression and keeps the roller away
from the main cylinder. Once in each revolution of the internal toothed disc
wheel a tappet on the outside thereof lifts the catch and allows the spring to move
the roller into contact with the cylinder.
The outer end of the spindle has a lever pivotted to it the lower end of which is
provided with a shackle lever and a friction wheel acted upon by the cam keyed
upon the driving shaft which by means of the lever at intervals withdraws the
intermittent printing roller away from the cylinder compressing the coiled spring
until the latch carried by the spindle falls and holds the roller out of contact until
the catch is again released.
The interval between each movement of the latch may be lengthened or shortened
by changing the spur wheels and pinions above mentioned.
Dated this 22nd day of September 1893.

I WILLIAM BUCKLEY of Brookside Print Works, West Leigh 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
ascertained in and by the following statement:-
This invention relates to machinery or apparatus employed for printing calico
and other woven fabrics, and more especially to such machines as are used for
printing borders or headings at intervals across the piece as in printing handkerchiefs,
scarves, and other similar intermittent printing.
The principal features of the invention are
(1) That the apparatus which brings the intermittent printing roller into action
is worked by direct gear from the mandrel of the same.
(2) That the action for bringing the said roller into contact with the work is
instantaneous.
(3) That the roller is moved out of contact with the work by means of a cam
running the same number of revolutions as the mandrel.
(4) That the length of interval at which the rollers are moved towards or from
the cylinder is easily regulated.
The manner in which my invention is to be performed or carried into practical
effect will be readily understood on reference to the sheet of drawings hereunto
annexed and the following explanation thereof.
Fig. 1 is a side elevation of part of the frame and main cylinder of a printing
machine showing the intermittent printing roller with my improved apparatus
applied thercto, Fig. 2 is a partial end view thereof, and Fig. 3 is a plan view taken
in the direction of the arrow on Fig. 2.
a is part of the main framing of the printing machine, & part of the main printing
cylinder, c the intermittent printing roller, and d the mandrel thereof. Upon this
mandrel I mount a worm or skewed spur wheel e which actuates a similar wheel f
mounted on a driving shaft g. On this shaft is also keyed a spur pinion h driving
through a carrier wheel i another spur wheel k on a short spindle parallel to the
driving shaft and carried by a fixing m on the machine side a.
On this short spindle at the other side of the fixing m is keyed a spur pinion n,
gearing with a disc wheel o mounted loosely upon the driving shaft. There is
also a camp with an adjustable tappet p (see detached view Fig. 4) keyed on the
driving shaft g and consequently running the same number of revolutions as the
mandrel d of the intermittent printing roller c.
Round a spindle q screwed into the block r which carries the mandrel d of the
roller c is coiled a powerful spiral spring s abutting against the block r and having
a constant tendency to force the roller c against the main cylinder . This spindle q
is also provided with a latch t (sliding through a slot made therein) which when in
action holds the spring s in a state of compression and keeps the roller c away from
the main cylinder bas shown at Figs. 1 and 3 on the drawings. The normal
position of the latch is shown at Fig. 3 it being held in this position by a spring t¹,
the projecting part coming against a steel washer and preventing the
spindle from sliding through the slot in the said washer, which the spindle just
fits, but once in each revolution of the toothed disc-wheel o the adjustable tappet pl
fixed on the outside thereof (see also detached view Fig. 4A) lifts the latch & bringing
the projecting part into the slot of the spindle q and allows the springs to move
the roller e into contact with the main cylinder b.
q
The outer end of the spindle 9 has a lever u pivotted to it, the lower limb of
which is provided with a shackle lever v and a friction wheel w which is acted

page_text: upon by the adjustable tappet p on the cam p which is keyed on the driving
shaft
g.
On referring to Fig. 3 it will be seen that so long as the roller c is held by the
latch t out of contact with the main cylinder the friction bowl w will remain clear
of the path of the tappet p', and it is held in this position by the shackle lever ⟫
the other end of which rests upon the rim or disc of of the disc wheel o, but once in
each revolution of this disc a notch o" therein comes opposite to the shackle lever v
which is then depressed by the spring pin x bringing the friction bowl to into the path
of the tappet p which striking against the bowl w causes the shackle lever v to
withdraw the intermittent printing roller c away from the cylinder compressing
the coiled spring s until the latch & carried by the spindle
falls down and holds
10
the roller out of contact until the latch t is again released by the action of the
tappet pl
The interval between each movement of the latch t may be lengthened or
shortened by changing the spur wheel k and adjusting the carrier wheel i thereto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The arrangement of mechanism substantially as hereinbefore described
and illustrated by the annexed drawings whereby the mechanism which brings the
intermittent printing roller into action is worked direct from the mandrel of the
same,
Secondly. The combination of the spring with the latch and cam for bringing
the roller instantaneously into action.
Thirdly. The application of a cam running the same number of revolutions as
the mandrel for the purpose of bringing the intermittent roller out of contact with
the work, and
Fourthly. The means substantially as described and illustrated for regulating
the intervals at which the intermittent printing roller is brought into action.
