Improvements in the Method of and Apparatus for Rendering Textile
Fabrics Waterproof by One Treatment or Process.
We, JOHN MILLER, Senior, and JOHN MILLER, Junior, both of 10, Cunliffe Villas,
Manningham, Bradford, in the County of York, Dyers and Finishers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to further improvements upon our Patents No. 9711
dated June 23rd 1890, and No. 14029 dated August 3rd 1892, and consists as
follows:-
-
After passing the fabric through the compartments containing a waterproofing
solution soluble in water, the fabric passes over suitable suction tubes or rollers
for extracting the superfluous moisture from both sides of the piece, these suction
rollers are constructed to prevent friction as the fabric passes over the said rollers,
and to assist the fabric in its passage, so doing away with any unnecessary drag
upon, and possible injury to the piece.
We construct these suction tubes or rollers of a suitable fixed tube or pipe,
connected with the blower or exhaust, and having a longitudinal slot or groove
upon its periphery, around this pipe are a series of tubes or rollers, revolving
clear of the suction tube proper, each alternate roller has an antifriction bowl
or runner fixed at each end, these antifriction runners rest within a groove at each
end of the suction tube, and a toothed bush or wheel encircling and resting upon
the antifriction runners moves the said rollers according to the speed of the fabric
as it passes through the machine, this toothed bush gears with or is driven by
any suitable driving mechanism.
One or more bands of air proof material are fixed round the ends of the suction
tubes, close up to the width of the material passing through the machine, these
bands are fixed in any suitable manner but easily removable and are for preventing
the suction being affected during operation when passing narrow goods througli
the machine.
We also preferably arrange the doctor for, regulating the supply of water-
proofing ingredients insoluble in water to the cylinder, of a steel or other metallic
roller covered with a layer of felt or other material, and such roller is adjusted
to the cylinder by means of gear wheel, cross shafts and screwed shafts and nuts,
so that the supply is uniform across the whole width of the cylinder, by this
means the doctors are not liable to warp with the heat, but an even, and regular
supply of the solution to the cylinder is always maintained; we also preferably
place upon the other side of the cylinder a similar doctor shown in our prior
patents, this doctor is for removing all superfluous or foul matter from the surface
of the cylinder, and prevents the same passing into the trough and injuring the
contents.
Also after the fabric has been treated to a waterproofing solution insoluble in
water and has passed round a series of heated cylinders, it passes under and over

page_text: rollers fixed within a trough or cistern containing hot water, this hot water is
found in practice to greatly fix or force the proofing solution into the fabric, so
improving its durability, flexibility and handle, the fabric then passes between
nipping rollers which press out the superfluous moisture and thence to the
calendaring machine where it is dried and finished.

Improvements in the Method of and Apparatus for Rendering Textile
Fabrics Waterproof by One Treatment or Process.
We, JOHN MILLER, Senior, and JOIN MILLER, Junior, both of 10, Cunliffe Villas,
Manningham, Bradford, in the County of York, Dyers and Finishers, 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 to further improvements upon our Patents No. 9711
dated June 23rd 1890, and No. 14029 dated August 3rd 1892 and consists as
follows:
Fig. 1 is a longitudinal section of part of one of our improved suction rollers.
Fig. 2 is an end view of our improved suction roller with method of driving
same.
Fig. 3 is a plan of our improved doctor roller and mechanism for adjusting same
to and from the cylinder.
Fig. 4 is an end view of one of the cylinders for supplying the waterproofing
ingredients insoluble in water, with doctors in position.
Fig. 5 is a sectional side view of part of our apparatus for waterproofing fabrics
by one continuous treatment or process, showing fabric passing from the heated
cylinder after having been waterproofed, to an additional compartment for fixing
such proofing.
Fig. 6 is a plan of Fig. 5.
After passing the fabric through the compartments containing a waterproofing
solution soluble in water, the fabric passes over suitable suction tubes or rollers,
for extracting the superfluous moisture from one or both sides of the piece; these
suction rollers are constructed according to this invention, to prevent friction
as the fabric passes over the said rollers, and to assist the fabric in its passage,
so doing away with any unnecessary drag upon, and possible stretch or other
injury to the piece.
We construct these suction tubes or rollers of a suitable fixed tube or pipe A,
connected with the blower or exhaust, and having a longitudinal slot or groove B
upon its periphery, around this pipe are a series of tubes or rollers C, revolving
clear of the suction tube proper, each alternate roller has an antifriction bowl or
runner 1 fixed at each end, these antifriction runners rest within a groove E at
each end of the suction tube A, and a toothed bush or wheel F encircling and
resting upon the antifriction runners D, moves the said rollers according to the
speed of the fabric as it passes through the machine; this toothed bush gears

page_text: with or is driven by any suitable driving mechanism, or in place of the toothed
bush the rollers may be operated in any other suitable manner.
One or more bands of air proof material are usually fixed round the ends of the
suction tubes, close up to the width of the material passing through the machine,
these bands are fixed in any suitable manner but easily removable, and are for
preventing the suction being affected during operation when passing narrow goods
through the machine.
We also preferably arrange or construct the doctor for regulating the supply
of waterproofing ingredients insoluble in water to the cylinder, in the form of a
steel or other metallic roller G, preferably round, fluted, or many sided as desired
and covered with a layer of felt or other material H, and such roller is adjusted
to the cylinder by means of screwed spindles J mounted upon each side of the
machine, operated by worm or bevel gearing K, cross shaft L, and hand wheel L',
upon these screwed spindles J are nuts M carrying the roller stud, or shaft N
which is also_mounted in sliding bearings P, by these means upon operating the
wheel L', the roller is moved up to or away from the cylinder equally its whole
length, so obtaining an uniform supply across the whole width of the cylinder N¹,
also the doctors are not liable to warp with the heat.
Upon the other side of the cylinder we preferably employ a second doctor in
the form of a blade R, of any material, carried in suitable bearings or carriers R¹,
and raised in and out of contact with the cylinder by any suitable means, this
doctor may or may not have a covering of felt or similar material, and is for
removing all superfluous or foul matter from the surface of the cylinder, and
prevents the same passing into the trough and injuring the contents.
As tue surface of this doctor roller G becomes worn or uneven, the roller is
moved so as to bring a fresh surface into contact with the cylinder.
Also after the fabric has been treated to a waterproofing solution insoluble in
water, and has passed round a series of heated cylinders, it passes under and
over rollers T, fixed within a trough or cistern Ụ containing hot water, this hot
water is found in practice to greatly fix or force the proofing solution into the
fabric, so improving its durability, flexibility and handle, the fabric then passes
between nipping rollers V or other means for pressing out or extracting the
superfluous moisture and thence to the drying cylinder or other drying machine
where it is dried and finished.
-
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. In apparatus for waterproofing fabrics the use and employment of suction
rollers A, around the external periphery of which are mounted antifriction runners
or rollers C, such rollers C being operated in the manner and for the purposes
substantially as set forth.
2. In apparatus for waterproofing fabrics the use and employment of adjustable.
doctors such as G, in the manner and for the purposes set forth.
3. In apparatus for waterproofing fabrics, the use and employment of an
additional compartment U containing hot water, through which is passed the
fabric after being proofed, in the manner and for the purposes set forth.
