Improvements in Machinery or Apparatus for Printing upon Calico
and other Textile Fabrics.
I JOHN MELLOR HAMPSON of Birch Vale in the County of Derby Millwright do
hereby declare the nature of this invention to be as follows:-
This invention relates especially to apparatus wherein it is required to withdraw
one or more of the "nips" or printing rollers from the fabric at stated intervals, when
printing say scarfs shawl patterns or other similar designs, the object of my invention
being to effect this withdrawal of the said " nips" or printing rollers by simple
positive and accurate mechanism.
In carrying out my invention. I employ a cam shaft and cams as usual for each
"nip" or printing roller, and upon each cam shaft I mount a spur wheel in gear with
a similar wheel on a short shaft driven by bevil gearing from a horizontal shaft which
is carried nearly beneath the centre of the crown wheel shaft. This shaft is provided
with a second bevil wheel in gear with a similar wheel on a vertical shaft which is
itself driven from the crown wheel shaft by bevel gearing.
The spur wheel on each of the short shafts above named may be made to drive two
cam shafts and thus if the four lower "nips" or printing rollers only are required to
be actuated intermittently, only two of the horizontal shafts above named will be
required, and by varying the bevel gearing which actuates the short shafts and spur
wheels above described the intervals during which the "nips" or printing rollers are
held in or out of action can be regulated as desired.
It will be seen that, as the cams are all actuated from the crown wheel shaft by
bevel and spur gearing the movement into or out of printing position of the several
"nips" or printing rollers will be effected in a positive manner, and the patterns and
borders can be regulated with the greatest accuracy.

page_text: I JOHN MELLOR HAMPSON of Birch Vale in the County of Derby Millwright do
hereby declare the nature of this invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates especially to printing machines wherein it is required to
withdraw one or more of the "
"
nips or printing rollers from the surface of the
fabric at stated intervals when printing (say) scarfs, shawl patterns or other similar
designs the object of my invention being to effect this withdrawal of the "nips" or
printing rollers by simple positive and accurate mechanism.
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 drawings
hereunto annexed and the following explanation thereof.
Fig. 1. is a side elevation and Fig. 2 a front view of so much of a four color
printing machine as is requisite to illustrate my invention.
"
"
a, a is part of the framing of the machine b, b the main cylinder and c, o the
nips” or printing rollers. In carrying out my invention I employ a cam shaft d, d
(and cam as usual) for each "nip" or printing roller, and upon each cam shaft
I mount a spur wheel e, e in gear with a similar wheel, f on a short shaft g, g driven
by bevil gearing h, h from a horizontal shaft i, i which is carried nearly beneath the
centre of the crown wheel shaft k, k.
This shaft i, i is also provided with a bevil wheel 1, 1 in gear with a similar
wheel m, m on a vertical shaft n, n which is itself driven from the crown wheel
shaft k, k by bevil gearing o, o.

The spur wheel on each of the short shafts 9, 9 above named may be made to
drive two cam shafts d, d (as shown at Fig. 1) and thus if the lower "nips or
printing rollers c, c only are required to be actuated intermittently only two of the
horizontal shafts i, i will be required and by varying the bevil gearing which actuates
the short shafts 9, 9 and spur wheels e, e and f, f the intervals during which the
"nips
or printing rollers c, c are held in or out of action can be regulated as
"
desired.
It will be seen that as the cams are all actuated from the crown wheel shaft k, k
by bevil and spur gearing the movement into or out of printing position of the several
nips" or printing rollers will be effected in a positive manner and the patterns and
borders can be regulated with the greatest accuracy.

page_text: Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
"
The arrangement (in printing machines of the class above specified) of bevil and
spur gearing substantially as herein before described and illustrated by the drawings
annexed for the purpose of driving the cams which move the " nips or printing
rollers into and out of printing position direct from the crown wheel shaft of the
machine.
