PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Rendering
Textile Fabrics Water-proof by One Treatment or Process.
We, JOHN MILLER Senior and JOHN MILLER Junior both of 14 Cunliffe
Villas, Manningham near Bradford in the County of York, Dyers and Finishers,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to further improvements upon our Patent No. 9711 dated
June 23rd 1890 and is as follows:-
For regulating the supply of ingredients insoluble in water, and to give an
uniform supply to the cylinders to be imparted to the fabric, we employ preferably
adjustable rollers or doctors placed upon and bearing against one side of the
cylinder over which the cloth passes, such doctors may consist of blades terminating
in indiarubber or felt or other suitable substance.
Or the doctors may be upon a centre with two or more blades, each blade being
covered with varying qualities of cloth or other yielding substance, these doctors
may also be of any suitable material and of various forms, and may be in the form
of rollers covered with rubber or other suitable material.
Also for pressing the ingredients into the cloth we employ a loose roller which
bears upon the cloth as it passes over the cylinder this roller is raised when required
by a screw or lever and cam, or other suitable means.
Also the cloth in passing through the machine (instead of passing over expanding
and suction tubes K. K. described in our Patent Specification before mentioned)
may pass over suitable reversible expanders, openers or rollers, fixed in a similar
position within the machine to the suction tubes K. K. aforesaid, then through a
trough or cistern and over reversible expanding suction tubes suitable for one
or two pieces in width, such suction tubes being constructed with internal divisions so
dispensing with covers, or the suction tubes may be stationary with a slot two or
more inches wide along one side of the tube having reversible perforated or slotted
expanding covers, at each end of these suction tubes according to the width of
fabric being operated upon, are slot covers for the purpose of covering the
perforations not bearing against the fabric.
The fabric then passes under and over two or more heated cylinders placed at
the top of the machine, over a compensating roller (for taking up the slack of the
fabric) expanders, and guide rods, to the cylinder working within the trough
containing ingredients insoluble in water, after passing over this cylinder the cloth
passes over and under two or more heated cylinders, (placed in any suitable position
within the machine) another series of compensating roller, expander and guide rods,
to and over a second cylinder, within a trough as before described, then forwards.
over guide rod and expander to two or more heated cylinders, after passing over
and under which it may pass to a tentering or other drying machine or to a beaming
or cutting down apparatus if desired.
The cylinders before described are driven by suitable gearing from driving
shafts upon which are suitable clutches, by means of which one or more sets of
cylinders may be employed or operated as desired according to the nature of the
fabric being operated upon.

Fig. 2, is a sectional end view of perforated water pipe for removing any
superfluous ingredients upon the cloth.
Figs. 3 and 4, are sectional end elevations of suction tubes.
Fig. 5, is a sectional side elevation of part of apparatus, showing the method of
passing the cloth through the same.
For regulating the supply of ingredients insoluble in water, and to give an
uniform supply to the cylinders, we employ preferably doctors, rollers or other
suitable device A, placed upon and bearing against one side of each cylinder B,
over which the cloth or fabric passes, such doctors may consist of blades terminating
in indiarubber, felt or other suitable substance C, and may be made to traverse
horizontally to and fro across the periphery of the cylinder, by means of a pivotted
lever D, operated by cam D¹, worm D2 and worm wheel D³, acting upon a wheel,
disc or projection E, on the spindle, stud or shaft E' of the said doctor.
Or the doctors may be upon a centre with two or more blades, each blade being
covered with varying qualities of cloth or other yielding substances, so as to
regulate the supply of ingredients insoluble in water, according to the nature of
the fabric being operated upon, these doctors may also be made of any suitable
material and of various forms, and may be in the form of rollers covered with
indiarubber or other suitable material.
Also for pressing the ingredients into the cloth we may employ a loose roller F,
within suitable bearings or slides G, which bears or rests upon the cloth or fabric H
as it passes over the cylinder B, this roller is raised when required by means of a
cam J, bearing against a projection J' upon the slide spindle J, the said cam being
operated by a lever K, or the said roller may be raised and lowered by any other
suitable means.
Also the cloth in passing through the machine instead of passing over the
expanding and suction tubes K. K. described and shown in our Patent Specification
aforesaid, may pass over suitable reversible expanders, openers or rollers (also
shown and described in our Patent Specification No. 97110) fixed in a similar
position within the machine to the suction tubes K. K. aforesaid, then through the
trough or cistern marked D in the aforesaid Specification.
Within or around the aforesaid trough we place preferably a suitable perforated
water pipe L, the jets of water from which playing upon both sides of the fabric
simultaneously, washes or removes any superfluous ingredients that may have still
adhered to the cloth, after which the cloth passes over suitable reversible expanding
suction tubes (shown at Figs. 3 and 4) suitable for one or two pieces in breadth,
such suction tubes being composed of an inner tube M having a slot M' of suitable
width, along one side, around this tube is a second reversible expanding tube or
cover N, for one or two pieces in breadth, this tube is perforated at each side, and

page_text: is reversible by means of handles N' see Fig. 3. Or the tubes may be made with
slots, projections and perforations P, upon the side bearing against the fabric, but
without the fluted expanding arrangement see Fig. 4, this tube or tubes being
employed for extracting all or superfluous moistures from the fabric before it passes
to the cylinder B working within the trough containing ingredients insoluble in water,
the suction being obtained in the manner shown and described in our Patent
Specification aforesaid.
At each end of these suction tubes according to the width of the fabric being
operated upon, may be slot covers for the purpose of covering the perforations
not in contact with the fabric. Or instead of slot covers, indiarubber or other
suitable flexible material may be employed, to hang over the perforations, which
by the suction are drawn to and cover up the perforations not in contact with
the cloth.
For more securely removing or extracting any superfluous moisture in certain
fabrics, we employ a draw roller R, over which and bearing against the same is
a pressure roller S, with lever S¹ and weight S2 for putting on the requisite pressure,.
and which may be raised or lowered by means of screw, cam or chain pulleys T.
When the fabric has passed over the suction rollers it then passes over and
between the draw and pressure rollers R and S, then over expander T, under aud
over one, two or more heated cylinders U placed at the top of the machine, over a
compensating roller U for taking up the slack of the fabric, then over another
expander T and guide rods T3 to the cylinder B working within the trough B₁
containing the ingredients insoluble in water, after passing over this cylinder, the
cloth or fabric passes over and under one or more heated cylinders V, (placed in.
any suitable position within the machine) over another series of compensating
roller V, expander V2, and guide rods V³, to a second cylinder B, working within
a trough as before described, then forwards under guide rod W and over expander W
to one, two or more heated cylinders X after passing over and under which it may
pass to a tentering or other drying machine, driven at a similar surface speed to
the waterproofing machine or a beaming or cutting down apparatus if desired.
The cylinders before described are driven by suitable gearing from driving
shafts, upon which are suitable clutches, by means of which one or more sets of
cylinders may be employed or operated as desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a waterproofing machine the use and employment of suction tubes,
perforated water pipe L, loose pressure rollers Fabove the cylinders B, operated
as and for the purposes such as shown and described.
2. The use and employment of adjustable doctors, rollers, or blades A, operated
as and for the purposes, such as shown and described.
3. The use and employment of compensating rollers U and V, draw and pressure
rollers R and S, in combination with the cylinders, guide rods, and expanders, in.
the manner and for the purposes, such as shown and described.
