Improvements in Apparatus for Printing Scarfs, Table Cloths, and
other Textile Goods.
I ALEXANDER STEVENSON YOUNG of the firm of William Rumney and Company
of Stubbins Print Works Ramsbottom 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:-
This invention relates principally to the apparatus for printing scarfs and other
similar goods for which Letters Patent bearing date the 7th December 1885
(No. 14974) were granted to me, the principal objects of the present invention
being to render such and similar printing machines available for printing both
sides of the piece simultaneously, to ensure more accurate fitting and coincidence
of the two patterns, and to dispense with the use of what are known as back
greys."
The nature of my said 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 annexed drawing and the following explanation thereof.
The drawing is an elevational diagrain showing the general arrangement of the
parts constituting a duplex printing machine according to my invention the working
details of which will be readily understood by any competent machine maker
accustomed to the construction of calico printing machines.
a is the first printing cylinder or bed roller and b is the second printing cylinder
or bed roller.
The
The engraved copper printing rollers are marked from 1 to 8 on the cylinder a
which prints the back of the piece and from 9 to 16 on the cylinder 6 which prints
the face of the piece. c is the batch roller upon which the piece to be printed
is wound and d is a bench or table onto which the printed cloth is delivered.
passage of the cloth through the machine is represented by a full line e that of
the "bump" for the first cylinder by a dotted line f second cylinder "bump" by
the dotted line and the first and second cylinder blankets by the dotted
lines g and g*. These all pass round guide rollers one of which in each case, is
adjustable so as to give and maintain the tension. The arrows show the direction
of movement in all cases.
One of the principal features of novelty in this arrangement consists in mounting
the two main cylinders or bed rollers at different heights, the horizontal distance
between their two centre lines being rather less than their diameter so that their
adjacent peripheries overlap each other slightly. One (or both) of these cylinders
is so fitted as to be adjusted vertically by screws or otherwise so as to separate
the two peripheries for threading the cloth through and to bring them close
together when working so as to prevent any shifting of the cloth in passing from
one cylinder to the other and thus to ensure the exact coincidence of the pattern
on both sides. This position of the cylinders also brings the engraved copper
rollers 8 and 9 nearer together than they could be brought if both the cylindere a
and & were mounted on the same horizontal plane.
The piece e printed on both sides as it leaves the last printing roller 16 on the
second cylinder or bed roller passes over steam drying boxes i and round the
steam drying cylinders and thence through the ordinary calendering and drawing
rollers to the bench d.

Another important feature of novelty in my invention is that the washable
bumps and f* after passing round their respective cylinders a and bare each
carried through a washing machine or then round steam drying cylinders m

to their respective main cylinders or bed rollers a and b and thus every part of
each "bump is thoroughly washed, dried, and stretched after each printing
operation before it is brought again into use, and thus all smearing or "flushing
of the colors is avoided and the use of "back greys" is entirely dispensed with,
and more accurate fitting insured.
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 general construction and arrangement of the duplex machine
substantially as hereinbefore described and illustrated by the annexed drawing for
printing scarfs table-cloths and other textile goods on both sides at once.
Secondly-The combination with a duplex cylinder printing machine of the
apparatus for washing, drying and stretching the "bumps" of the two cylinders
after each printing operation and before returning to their respective cylinders
thereby dispensing with the use of "back greys."
Thirdly-The method of mounting the two cylinders of a duplex printing
machine so that their adjacent peripheries overlap and so that they (or one of them)
can be adjusted vertically so as to separate their surfaces or bring them close
together substantially as hereinbefore described and illustrated by the drawings
annexed, whereby perfect coincidence of the patterns is secured and the distance
between the last copper roller of the first cylinder and the first copper roller of
the second cylinder is diminished.
Dated this 16th day of February 1893.
