PROVISIONAL SPECIFICATION.
Improvements in Combined Blanket Washing and Printing
Machines.
I, JAMES POLLARD, of Newton Bank Print Works, Hyde, in the County
of Chester, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in combined blanket washing and printing
machines and the chief object of my invention is to improve the mode of driving
the washing and drying gear.
Hitherto it has been customary in such machines to drive from a back or
countershaft driven from the star wheel, and a great drawback to this arrangement
is that when the printing rollers are changed for others of different diameters the
printing bowl is driven at a different surface speed and to compensate for this
change of speed it is necessary to employ cone pulleys or equivalents in order to
regulate the speed of the blanket or endless band of material upon which the
fabric is printed.
To obviate this I propose to drive the printing bowl by frictional contact from
the printing rollers as heretofore, and to drive all the washing and drying gear
directly from the printing bowl axis so that any change of speed in the rotation
of the printing bowl causes a corresponding change in the speed of the washing
and drying gear without any further regulation.
Dated this 19th day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Combined Blanket Washing and Printing
Machines.
I, JAMES POLLARD, of Newton Bank Print Works, Hyde, in the County of
Chester, 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 aud by the following statement:-
My invention relates to improvements in combined blanket washing and printing
machines and the chief object of my invention is to improve the mode of driving
the washing and drying gear.
Hitherto it has been customary in such machines to drive from a back or
countershaft driven from the star wheel, and a great drawback to this arrangement
is that when the printing rollers are changed for others of different diameters the
printing bowl is driven at a different surface speed and to compensate for this
change of speed it is necessary to employ cone pulleys or equivalents in order
to regulate the speed of the blanket or endless band of material upon which the
fabric is printed.
To obviate this I propose to drive the printing bowl by frictional contact from
the printing rollers as heretofore, and to drive all the washing and drying gear
directly from the printing bowl axis so that any change of speed in the rotation of
the printing bowl causes a corresponding change in the speed of the washing and
drying gear without any further regulation.
And in order that my invention may be fully understood and readily carried into
effect I have annexed hereunto a sheet of drawings upon which is shown a side

elevation of so much of a combined blanket washing and printing machine as is
necessary for the illustration of my improvements.
In these views, a designates the main printing bowl the driving of which is not
illustrated as it may be driven by frictional contact from the printing rollers as
now customary, or in any other convenient and suitable way. On the axis of the
printing bowl a I fix a chain wheel which drives by means of a chain b a chain
wheel fixed on a countershaft c on which are also fixed two other chain wheels;
from one of these chain wheels on the countershaft c a chain d passes to a chain
wheel fixed on the axis of one of the series of driving cylinders e which are
geared together in the usual way; from the remaining chain wheel on the counter-
shaft ca chain passes to a chain wheel on a stud g on which is fixed a second chain
wheel from which motion is transmitted by means of a chain h to the fixed bowl i of
the blanket washer.
The blanket is indicated by the line; and beginning with the printing bowl a it
takes the following course :-
Over guides 2, 3, 4, it passes down the washer under the guide 5 and up again to
the fixed bowl i being washed as it passes down and up by the ordinary arrange-
ment of spurt pipes and brushes & then between the nip of the fixed bowl i and the
adjustable bowl m it passes over the guide 6 to the first drying cylinder e and thence
through the nest of drying cylinders being guided by the rollers 7, 8, 9, 10, 11,
12, 13, 14, 15, to a roller 16 whence it passes over and under a series of guides 17
then back under and over the guides 18, 19, 20, 21, 22, 23 and 24 to the printing
bowl a.
It will be readily understood that as the blanket washing rollers and the drying
cylinders are both driven by chain gearing from the axis of the printing bowl that
any change in the speed of the latter will at once cause a corresponding change in
the former.
I wish it to be understood that I do not limit myself to chain gear although I
prefer to employ it as being the most suitable means to use for the purposes of my
invention.
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 :-
1. In a combined blanket washing and printing machine, driving the blanket
washing and drying gear directly from the axis of the printing bowl in order that
any change of speed in the rotation of the printing bowl may cause a corre-
sponding change in the speed of the washing and drying gear without any further
regulation.
2. The general combination and arrangement of parts embodying my improve-
ments in combined blanket washing and printing machines substantially as herein
described and illustrated, for the purpose specified.
Dated this 22nd day of November 1892.
