Improvements in the Method of and Means for Cleansing
Calico Printers' Blanketing, Floor Cloth Printers' Blanketing,
and the like.
I ABEL BUCKLEY WIMPENNY, Oak Villa, Hayfield, in the County of Derby,
Calico Printer, do hereby declare the nature of this invention to be as follows:-
My said invention relates to improvements in the method of and means for
cleansing calico printers blanketing floor cloth printers blanketing and the like.
Under the present practice it is usual when cleansing such blanketing, to subject the
blanketing to the action of reciprocating or revolving brushes by means of which
and with the aid of water or other liquid the soiled surface of the blanketing is more
or less cleansed.
This method is subject to certain disadvantages, the brushes operating on the
colours with which the surface of the blanketing is charged, have a tendency to rub
the colours into the fabric and cause the same to spread over a larger surface. More
over the brushes become cloggod with colour and lint from the blanketing which
renders them less effective.
The object of my invention is to obviate these disadvantages.
To effect this
I remove the greater portion of the colour from the blanketing before the same is
operated upon by the brushes of the washing apparatus.
In carrying my invention into effect I provide a cylindrical roller or it may be
a series of rollers disposed across the width of the blanketing. The roller is
mounted in adjustable bearings so as to bring the soiled surface of the blanketing
into contact with the roller before being operated upon by the brushes of tho
washer. The roller or rollers is or are driven by a belt or suitable gearing in a
direction contrary to the direction of traverse of the blanketing and at a speed
a little in excess of the same. The roller or rollers may be of cast iron the
surface of which it is essential should be very smooth and highly polished. If desired
the surface of the rollers may be coated or plated with any suitable metal not likely to
be chemically affected by the colouring matter which plating may be most conveniently
effected by electro-deposition. By bringing the revolving roller or rollers into light
contact with the soiled surface of the blanketing, the greater portion of the colouring
matter with which the blanketing is charged adheres to the smooth polished surface
of the roller or rollers. The blanketing being deprived of the greater mass of colour
is more easily cleansed by the brushes of the washer, and as the necessity for prolonged
or severe scrubbing is obviated, the life of the blanketing is thereby prolonged.
Upon the other side of the roiler or rollers I mount a "doctor" or "doctors" of any
suitable metal or material which operates to cleanse the surface of the roller or rollers
from the color, lint and other matters which adhere to the surface. The colouring
matter is discharged by the doctor into a suitable inclined trough and thereby led
away to a convenient receptacle. A stream of water may if desired be directed into
the trough to liquefy the colour sufficiently to enable it to flow down the trough. If
considered desirable the interior of the roller or rollers may be heated by means of gas,
steam or other heating means in order to increase the adhesive properties of the roller
or rollers.

page_text: Where the blanketing has been used with a single colour of costly nature a
considerable saving will be effected by the recovery of a quantity of such colour
by means of my invention. Although I have described my invention as being
applied as an adjunct to a blanket washing apparatus I do not confine myself to this
use alone.
For instance the apparatus might be applied to a calico printing machine, floor
cloth printing machine and the like, so as to deprive the blanketing of the colour
during the working of the machine or at intervals. By these means the blanketing
would not require to be washed or cleansed so frequently as is at present the case.

Improvements in the Method of and Means for Cleansing
Calico Printers' Blanketing, Floor Cloth Printers' Blanketing,
and the like.
IABEL BUCKLEY WIMPENNY, Oak Villa, Hayfield, in the County of Derby,
Calico Printer, 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 and accompanying drawings:-
My said invention relates to improvements in the method of and means for cleansing
calico printer's blanketing, floor cloth printer's blanketing, paper stainer's blanketing
and the like. Under the present practice it is usual when cleansing such blanketing,
to subject the blanketing to the action of reciprocating or revolving brushes, by
means of which and with the aid of water or other liquid the soiled surface of the
blanketing is more or less cleansed.
This method is subject to certain disadvantages, the brushes operating on the
colours with which the surface of the blanketing is charged, having a tendency to rub
the colours into the fabric and cause the same to spread over a larger surface. More-
over the brushes become clogged with colour and lint from the blanketing which
renders them less effective.
The object of my invention is to obviate these disadvantages.
To effect this I remove the greater portion of the colour and lint from the
.blanketing before the same is operated upon by the washing apparatus, by means of a
highly polished revolving roller adjusted so as to be lightly in contact with the soiled
surface of the blanketing. The roller revolves in a direction contrary to the direction
of the traverse of the blanketing and at a speed in excess of the same.
A convenient
speed to run the roller is about 3 times that of the blanket but this may be varied as
desired. The greater portion of the colour and lint with which the blanketing is
charged is thus caused to adhere to the surface of the revolving roller.
And in order that my invention may be more fully understood I will now
describe the same with reference to the accompanying sheet of illustrative drawings.
In the said drawings
Fig. 1 is a front elevation of an apparatus constructed in accordance with my
invention a part only of such apparatus being shown for want of space.
Fig. 2 is an end elevation of the apparatus,
Fig. 3 is a detail view of the means of adjusting the "doctor" to compensate
for wear.

page_text: Fig. 4 shows two of my improved cleansing rollers used in conjunction with a.
blanket washer.
A roller a preferably of cast iron and having a highly polished surface is
mounted to revolve in bearings carried by end standards b. If desired the surface
of the roller a may be coated or plated with any suitable metal not likely to be
chemically affected by the colouring matter, which plating may be most conveniently
effected by electro-deposition.
The shaft a' of the roller a is mounted in bearing blocks c adjustable vertically
in the pedestals d, by means of finely chased adjusting screws d' operated by hand
wheels d. Upon the shaft a¹ is mounted a chain wheel a by means of which the
roller a is driven from any suitable source. It will be understood that the roller a
may be formed of any convenient length to suit the width of blanketing to be
operated upon. The blanketing to be operated upon and indicated by the dotted line e
is passed beneath the roller a and over the carrying roller f.
The roller a is adjusted by means of the hand wheel so as to bring its
circumference lightly in contact with the soiled surface of the blanketing e, and the
colour and lint with which the surface of the blanketing e is charged, adheres to
the periphery of the roller a. A "doctor" is provided to cleanse the surface of
the roller from the colour and lint obtained from the blanketing, and maintain the
periphery of the roller bright and clean.
The doctor g is held in clamps the lower or bed clamp being formed with
trunnions, and can be adjusted by means of thumbscrews h, in angular slots i
formed in the brackets j bolted to the pedestals d. The method of adjusting the
doctor g is shown in Fig. 3.
The trunnions 92 of the doctor g are carried in bearing pieces k which are raised
and lowered towards and from the roller a by means of thumbscrews h.
Upon the ends of the trunnions of the doctor, are mounted levers to which
are attached springs m connected at their lower ends to pins n secured to the
brackets j, which serve to maintain the doctor g against the periphery of the
roller a with a suitable degree of pressure. The colour and lint scraped from.
the periphery of the roller a by the doctor g is discharged into a trough o which is
carried by the brackets j bolted to the standards b. The colour discharged into the.
trough can be emptied into a vessel and carried away when requisite. Upon
leaving the roller a the blanketing is led away to a suitable washing apparatus.
The blanketing being deprived of the greater mass of colour and liat is more.
easily cleansed by the brushes of the washer, and as the necessity for prolonged
or severe scrubbing is obviated, the life of the blanketing is thereby prolonged.
Moreover the greater mass of colour being removed before the blanketing is
operated upon by the washer, the waste water of the washer is less foul and easier
to deal with in the settling and filtering operations, required to be gone through
before the waste water can be discharged into the river or stream from which it.
may have been originally taken.
If considered desirable the interior of the roller may be heated in any well
known manner by means of gas, steam or other heating means in order to increase.
the adhesive properties of the roller.
"
Where the blanketing has been used with a single colour of costly nature a
considerable saving will be effected by the recovery of a quantity of such colour
by means of my invention.
Fig. represents two of my improved cleansing rollers in conjunction with a.
blanket washer. The blanketing e coming from the printing machine passes over-
the carrying roller and from thence to the first cleansing roller which operates
upon the soiled surface of the blanketing and deprives it of a large quantity of
colour and lint with which it is coated. The blanketing passing to the second.
cleansing roller is further treated and cleansed before entering the washer.
In the washer it is operated upon by the revolving scrubbing brushes p q and
revolving drying brush and passes from thence to the drying cylinders not shown.
in the drawings.

page_text: If considered desirable I may replace the revolving scrubbing brush p by my
improved cleansing roller and remove the colour from the surface of the cleansing
roller by means of a revolving brush supplied with water or liquid by means of
a spurt pipe or by other suitable means." It will be understood that the blanket
washer shown in Fig. 4 in conjunction with my improved cleansing rollers is of
an ordinary construction and forms no part of my invention.
Although I have shown two of my improved cleansing rollers in conjunction with
a blanket washer one cleansing roller only may be used if desired.
Although I have described my invention as being applied as an adjunct to a
blanket washing apparatus I do not confine myself to this use alone.
For instance the apparatus might be applied to a calico printing machine, floor
(cloth printing machine or the like, so as to deprive the blanketing of the colour and
lint during the working of the machine or at intervals.
By these means the blanketing would not require to be washed or cleansed so
frequently as is at present the case.
Instead of a roller of cast iron being used as described I might use other material
capable of being formed with a smooth highly polished surface such as wood, glass or
the like.
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. As means for cleansing calico printers blanketing and the like, the employment
of a highly polished, or plated roller, or series of rollers, used either with a cold or
heated surface, and revolving in light contact with the soiled surface of the blanketing
whereby the colour and lint or a large proportion of the colour and lint with which
the blanketing is charged, adheres to the surface of the roller substantially as
described and shown.
2. The general arrangement construction and combination of parts comprising
the improved apparatus for cleansing calico printers blanketing and the like,
substantially as described and shown with reference to Figs. 1 to 3 of the drawings.
Dated this 9th day of April 1897.
