IMPROVEMENTS IN APPARATUS FOR PRINTING SCARFS AND OTHER SIMILAR GOODS
Year: 1885

page_text: 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 any invention for "IMPROVEMENTS IN APPARATUS
FOR PRINTING SCARFS AND OTHER SIMILAR GOODS to be as follows:-
This invention relates to machines for printing patterns upon scarfs and other
similar goods whereon it is required to print the body of the cloth with a runing
or other pattern upon the centre part and a border along each side, and at certain
regulated intervals (according to the desired length of the scarf or other article) to
raise these printing rollers off the surface and to print across the interval thus left,
two transverse borders so as to form the ends of the scarfs or other goods.
This I propose to effect upon the ordinary cylinder printing machine by a simple
arrangement of mechanism, dispensing with all levers and with a great portion of
the toothed gearing usually employed for such purpose.
Outside each copper printing roller (or "nip") which it is required to bring into
or out of contact with the work at intervals I mount in suitable bearings a shaft,
and upon each of these shafts is fixed a cam which works between two small rollers
attached to a slide which carries the mandrel of the copper printing rollers (or
"Dip") in such a manner as to remove the said roller away from the cylinder of
the machine and put it back to the cylinder at the exact time required to form the
pattern.
The mandrel of each "nip" can drive its own cam shaft, or preferably the shaft
can be driven by chain gearing in the following manner.
Across the top of the machine I mount a shaft which is driven from the crown
wheel. Upon the other end of this shaft is keyed a spur wheel which drives a
change wheel, the diameter and the number of teeth upon which regulates the
length of the scarf or other article. Upon the end of this change wheel is fixed a
DanQ877

upon the axis of the cylinder of the machine.
Upon the side of this chain or stud wheel is fixed a spur wheel driving a series
of spur pinions (one to each 'nip') and to these pinions are fixed small chain or
stud wheels each driving (by means of an endless chain) a similar wheel fixed upon
its corresponding cam shaft.
"
The length of the intervals at which the respective cams move their corre-
sponding "nips or copper rollers towards or from the cylinder will regulate the
length of the scarf, and this can be effected by altering the change wheel and cams.

I ALEXANDER STEVENSON YOUNG of the firm of William Rumney & Co of
Stubbins Print Works Ramsbottom in the County of Lancaster Calico printers do
hereby declare the nature of my invention for "IMPROVEMENTS IN APPARATUS FOR
PRINTING SCARFS AND OTHER SIMILAR GOODS" 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 machines for printing patterns upon scarfs and other
similar goods whereon it is required to print the body of the cloth with a running
or other pattern upon the centre part and a border along each side and at certain
regulated intervals (according to the desired length of the scarf or other article) to
raise these printing rollers off the surface and to print across the interval thus left,
two transverse borders so as to form the ends of the scarfs or other goods.
This I propose to effect upon the ordinary cylinder printing machine by a simple
arrangement of mechanisın, dispensing with all levers and with a great portion of
the toothed gearing usually employed for such purpose.
The nature and object of my invention will be readily understood on reference
to the annexed sheet of drawings marked with figures and letters of reference
corresponding with those in the following explanation.
Fig. 1. in the annexed drawing is an elevation (drawn partly in section) of so
much of one end of an eight-color cylinder calico printing machine as is necessary
to illustrate my invention and Fig. 2. is a similar view of the other end of the
same, four of the rollers only being shown in position.
a, a is the main framing of the machine and the dotted circle, b, b is the main
cylinder or bowl, cc, are the copper printing rollers, (or "nips" as they are termed)
and outside each of these rollers c, c which it is required to bring into or out of
contact with the work at intervals, I mount in suitable bearings a shaft d, d and
upon each of these shafts is fixed a cam e, e which works between two small
rollers, attached to a slide g, g which carries the mandrel c* of the copper
printing roller (or "nip") c, c in such a manner as to remove the said roller away
from the cylinder or bowl d, d of the machine and put it back to the said cylinder
at the exact time required to form the pattern.
Instead of the cam e, e working between the two small rollers f, f as shown at
the right hand of Fig. 1. it may work between a roller f and a bar fl as shown
at the left hand of the same. Fig. but for those rollers which are below the
centre, only one small roller is required to put the roller up to the cylinder as the
weight of the roller itself will bring it away as the cam e, e revolves.
The mandrel c* of each "nip" c, c can drive its own cam shaft d, d or preferably
the shaft can be driven by chain gearing in the following manner.
Across the top of the machine I mount a shaft h, h which is driven from the crown
wheel, by a spur wheel k, k which drives a change wheel 1, the diameter and
the number of teeth upon which regulates the length of the scarf or other article.

page_text: Upon the other end of the shaft h, h is fixed a small stud wheel m, m driving
(by means of an endless chain n n) a similar wheel o, o loose upon the axis of the
cylinder b, b of the machine.
Upon the side of this chain or stud wheel m, m is fixed a spur wheel p, p driving
a series of spur pinions 9 9 (one to each "nip") and to these pinions are fixed small
chain or stud wheels r, each driving (by means of an endless chain) a similar
wheel fixed upon its corresponding cam shaft d, d.
The length of the intervals at which the respective cams e, e move their corre-
sponding "nips" or copper rollers c, c towards or from the cylinder or bowl b, b
will regulate the length of the scarf, and this can be effected by altering the change
wheel, and the cams e, e.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is =
The adaptation and combination in cylinder calico printing machines of endless
chains and stud wheels for the purpose of driving cams working direct upon the
copper rollera or "nips" of such printing machines; whereby a more direct action
than heretofore is obtained on the cams for moving, the rollers to and from the
cylinder or bowl, and all springs levers, and intermediate driving wheels are
dispensed with, substantially in the manner and for the purposes herein-before
particularly set forth and described, and illustrated by the drawings annexed.
