PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing and Cleansing Calico
Printer's Blanketing.
I, ALBERT JOSEPH CUNLIFFE, of Kem Mill Print Works, Whittle-le-Woods,
near Chorley, in the County of Lancaster, Calico Printer, do hereby declare the
nature of this invention to be as follows:-
-
My said invention relates to improvements in apparatus for washing and cleans-
ing calico printers' blanketing.
Under my improved arrangement I provide a trough or receptacle to contain
the brushes the said trough or receptacle being of any suitable or convenient
shape.
Within the trough I provide a carrying or backing roller the blanketing passing
partly around this roller on its way through the apparatus. Around the roller
I arrange a series of revolving brushes which act upon the face of the blanketing
as it is carried round. I make the said backing roller of sufficiently large diameter
to admit of the use of a sufficiently large number of revolving scrubbing brushes,
and by the use of a single backing roller of large circumference the blanketing
is preserved from being led up and down over different guiding and backing
rollers, which tend to injure the blanketing to run it crooked and also absorb
power. In juxtaposition to the revolving scrubbing brushes I arrange spurt
pipes which discharge cold or warm water upon the face of the blanketing as it is
successively subjected to the action of the scrubbing brushes.
The scrubbing brushes are driven at a high speed and are set by suitable adjust-
ing means so as to act lightly upon the surface of the blanketing. This has an
equally good cleansing effect and does not fatigue the blanketing so much as when
the brushes are set hard against the surface. Another advantage is that with this
light contact the brushes are more easily driven and do not absorb so much power
as when set close. The large central backing roller presents a smooth and unyield-
ing backing to the action of the scrubbing brushes. After leaving the backing
roller and scrubbing brushes the blanketing may be led between squeezing rollers
or over one or more drying brushes to remove superfluous moisture and thence to
the drying cylinders. The water falling into the trough or receptacle is drained
off by a suitable outflow.
By forming man holes in the sides and ends which can be closed with doors
the user of the apparatus may at any time examine and cleanse the apparatus from
within and beneath.

I, ALBERT JOSEPH CUNLIFFE, of Kem Mill Print Works, Whittle-le-Woods,
near Chorley, in the County of Lancaster, Calico Printer, do hereby declare the
nature of this invention and in what inanner the same is to be performed to be
particularly described and ascertained-in and by the following statement and
accompanying drawings:-
My said invention relates to improvements in apparatus for washing and cleans-
ing calico, printers' blanketing.
Under my improved' arrangement I provide a trough or receptacle to contain
the brushes, the said trough or receptacle being of any suitable or convenient
shape.
Within the trough I provide a carrying or backing roller the blanketing passing
partly around this roller on its way through the apparatus. Around the roller
I arrange a series of revolving brushes which act upon the face of the blanketing
as it is carried round. I make the said backing roller of sufficiently large diameter
to admit of the use of a sufficiently large number of revolving serubbing brushes,
and by the use of a single backing roller of large circumference the blanketing
is preserved from being led up and down over different guiding and backing
rollers, which tend to injure the blanketing, to run it crooked and also absorb
power. In juxtaposition to the revolving scrubbing brushes I arrange spurt
pipes which discharge cold or warm water upon the face of the blanketing as it is
successively subjected to the action of the scrubbing brushes.
My invention will be more readily understood by a reference to the accompany-
ing drawings in which,
Fig. 1 is a sectional side elevation of my improved blanket washing apparatus.
Fig. 2 is a sectional end view of same, and
Figs. 3 and 4 represent adjustable bearings for the revolving scrubbing brushes.
The blanketing to be treated, represented in Fig. 1 by the dotted line, as it
enters the apparatus is passed around the backing-roller a mounted in suitable
bearings in the frame or trough A of the apparatus. The backing roller a is of
unusually large dimensions, about three times the diameter of the backing rollers
usually employed, which enables me to employ a larger number of scrubbing
brushes than would be possible with a small backing roller. Moreover I am
enabled to dispose all the scrubbing brushes below the centre of the backing roller
which is very advantageous in practice. These revolving scrubbing brushes bare
represented in the drawings as being five in number although I do not confine
myself to this number.
Spurt pipes c deliver the requisite quantity of water upon the blanketing in its
passage through the machine.
'
The scrubbing brushes b are driven at a high speed by suitable belting or gear-
ing and are mounted in adjustable bearings. The adjustable bearings are separately
shown in Figs. 3 and 4 and consist of brackets & bolted to the sides of the appa-
ratus. The brackets & are provided with ways d' upon which slide bearing
blocks e operated by the adjusting screws f by means of which the scrubbing
brushes may be readily advanced towards or retracted from the backing-roller a.
The revolving scrubbing brushes 6 are adjusted so as to act lightly upon the sur-
face of the blanketing. This has an equally good cleansing effect and does not
fatigue the blanketing s
so much as when the brushes are set hard against the
surface, which vigorous scrubbing is essential in an apparatus containing only two

page_text: or three scrubbing brushes so as to effectually cleanse the blanketing. Moreover
by increasing the number of scrubbing brushes as in my improved apparatus a
much less quantity of water may be employed and thus the blanketing does not
get saturated.
Another advantage is that with this light contact the brushes bare more easily
driven and do not absorb so much power as when set close. The large central
backing roller a presents a smooth and unyielding backing to the action of the
scrubbing brushes. After leaving the backing roller and scrubbing brushes the
blanketing is led over a roller g and between the adjustable roller h and drying
brush to remove superfluous moisture and from thence to the drying cylinders.
The water falling into the trough or receptacle A is drained off by a suitable
outflow j.
Man holes k are formed in the sides and ends which are closed with doors / so
that the user of the apparatus may at any time examine and cleanse the apparatus
from within.
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
1) The improved blanket washing apparatus arranged and constructed sub-
stantially as described and illustrated.
2) In an apparatus for washing and cleansing calico printers blanketing con-
structing and arranging the backing roller so as to obtain an increased number of
scrubbing brushes substantially as described and shown.
