IMPROVEMENTS IN MACHINERY FOR TREATING WATERPROOFED FABRICS
Year: 1885

page_text: I ISIDOR FRANKENBURG, of 88 Greengate, Salford, Lancashire, India-rubber
Manufacturer, do hereby declare the nature of said Invention for IMPROVEMENTS
IN MACHINERY FOR TREATING WATERPROOFED FABRICS, to be as follows:-
C
My invention relates to improvements in machinery employed in the treatment
or manufacture of waterproofed fabrics, my chief object being to protect the
operatives engaged in such manufacture from noxious fumes and dust.
In applying my Invention to a machine for "curing" fabrics, commonly called
zincoloring" fabrics, I form a chamber by enclosing the part of the machine, which
contains the acid or "curing" trough, by means of a glass or other suitable casing.
I form apertures at the upper or other part of the casing through which the fumes
pass; if required a fan or other means may be used to create the draught necessary
for exhausting the chamber.
The fabric to be "cured" or treated enters the enclosed part of the machine
between rollers or through a narrow slit in the casing and passes over the roller in
the "curing" trough; the fabric is or may be then dried by traversing it over
steam chests or otherwise after which it passes out of the chamber through a
narrow slit in the casing or over other rollers if required before being wound upon
the beam at the other end of the machine.
The noxious fumes which are given off by the acid in the "curing" trough and
also the fumes liberated by the action of heat on the fabric pass upward or are
drawn out of the chamber and so pass out of the room or building.
I propose to keep the acid employed in the "curing" process in a suitable vessel
placed outside the casing at a level above the trough and I arrange a tap or valve
also outside the casing which tap can be adjusted as required so as to regulate the
supply of acid. I connect the stopper for the trough to a lever or levers which
projects through the casing and is under the control of the operative; by this
means the trough may be emptied quickly when required.
In applying my improvements to machines in which farina, chalk, or other
substance is applied to waterproofed fabrics, I enclose the whole, or the necessary
part of the machine, and conduct the fumes or dust away as already described.

I ISIDOR FRANKENBURG, of 88 Greengate, Salford, Lancashire, India-Rubber
Manufacturer, do hereby declare the nature of said Invention for "IMPROVEMENTS
IN MACHINERY FOR TREATING WATERPROOFED FABRICS," and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to improvements in machinery employed in the treatment
or manufacture of waterproofed fabrics, my chief object being to protect the
operatives engaged in such manufacture from noxious fumes and dust.
In applying my Invention to a machine for "curing" fabrics, commonly called
"zincoloring" fabrics, I form a chamber by enclosing the part of the machine
which contains the acid or "curing" trough, by means of a glass or other suitable
casing. I form apertures at the upper or other part of the casing through which
the fumes pass; if required a fan or other means may be used to create the draught
necessary for exhausting the chamber.
The fabric to be "cured" or treated enters the enclosed part of the machine
between rollers or through a narrow slit in the casing and passes over the roller in
the "curing" trough; the fabric is or may be then dried by traversing it over
steam chests or otherwise after which it passes out of the chamber through a
narrow slit in the casing or over other rollers if required before being wound upon
the beam at the other end of the machine.
The noxious fumes which are given off by the acid in the "curing" trough and
also the fumes liberated by the action of heat on the fabric pass upward or are
drawn out of the chamber and so pass out of the room or building.
I propose to keep the acid employed in the "curing" process in a suitable vessel
placed outside the casing at a level above the trough and I arrange a tap or valve
also outside the casing which tap can be adjusted as required so as to regulate the
supply of acid. I connect the stopper for the trough to a lever or levers which
projects through the casing and is under the control of the operative; by this
means the trough may be emptied quickly when required.
In applying my Improvements to machines in which farina, chalk, or other
substance is applied to waterproofed fabrics, I enclose the whole, or the necessary
part of the machine, and conduct the fumes or dust away as already described.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying two Sheets of Drawings reference
being had to the figures and letters marked thereon.
Figure 1 is an elevation partly in section illustrating my Invention as applied to
a machine for "curing" or as it is commonly called "zincoloring" fabrics. Fig. 2
is a plan of part of the same, and Fig. 3 is an elevation illustrating my Invention
as applied to part of a machine for applying farina, chalk or other substance to
waterproofed fabrics.
Similar letters refer to similar parts throughout the several views.
In Figs. 1 and 2.-a is the outer casing which I employ to inclose the machine.

page_text: This casing is in communication at the top with the chimney or other outlet and
has a suitable inlet for air at or near the bottom; b is the roller on which the
fabric to be treated is wound and b¹ the beam or roller on which the treated or
cured fabric is wound or batched. The fabric passes from the roller b into the
machine through a slit a¹ in the casing a, under a guide roller c to the roller d in
the curing trough d' then round the guide roller cover the guide c² round the
guide rollers c³ c c over the steam chests e and out of the machine through the
slit or opening a², thence between the boards or their equivalents a³ to the roller b¹
where it is batched; one of the boards a³ is hinged to the casing a so that it may
be raised into the position indicated by dotted lines, Fig. 1, when it is desired to
inspect the fabric. Near the top of the casing a there is or may be an exhaust fan
driven from the pulley f to insure a thorough draught through the casing and thus
draw into the chimney or other outlet all the noxious fumes and vapours which
escape from the curing trough d¹ and the cured fabric. If necessary or desirable
I propose to employ near the fan or outlet ammonia or other suitable chemicals to
neutralise and render harmless the noxious properties of the escaping fumes; this
is desirable where the fumes pass from the enclosed machine to the outside of the
building only. In front of the curing trough d' there is a guide roller g held in
brackets pivoted at g¹ and when it is desired to guide the fabric clear of the
roller & the roller g can be raised by means of the handle g2 which is then secured
in position by means of a pin in the rack 93 so that the fabric passes directly from
the roller g to the guide roller c. The curing trough d' is supplied with acid or
curing liquor from the jar or reservoir h which is placed outside the casing a and
is connected by the pipe to the trough d¹. The trough d¹ may be quickly
emptied by means of the lever i one end of which projects through the casing a.
The lever i is pivoted at i¹ and connected to the plug or stopper 2 of the discharge
pipe 3 so that by moving the handle of the lever i the plug may be raised and
the liquor in the trough d allowed to escape through the pipe ³.
In Fig. 2, the curing trough d¹ projects beyond the casing, the pipe h¹ for filling
it as well as the pipe for discharging the curing liquor are outside the casing;
the projecting portion of the trough is preferably covered with glass.
In Fig. 3 the fabric passes into the machine from the roller b, through the
opening a¹ over the guide roller c, under the roller c', to the roller d in the curing
trough d¹ thence guided by the rollers c c the fabric passes directly upward to
that part of the machine where the farina or other substance is applied by means
of the shoot or hopper j and the "doctor" or blade k, then over the steam chest e
out of the casing at a² over the guide c¹º, roller c¹¹, under the cloth roller l over
the guide roller c¹² between which and the guide roller c¹³ it is brushed by the
revolving brush m previous to being wound or batched upon the beam or roller b².
I would have it clearly understood that I do not limit myself to the exact details
herein described and shown as the same may be varied or modified without
departing from the nature of my Invention, for example,-The form of the
casing a may be varied or modified and in some cases instead of inclosing the
machine in a special casing it may be more convenient to place the machinery in
a separate room or chamber in communication with a chimney or other outlet and
to guide the fabric into and out of such chamber the machinery being so arranged
as to be operated from outside the said chamber substantially as herein described
thus obviating the necessity for the operatives having to enter the room and
protecting them from noxious fumes and dust.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be perforined I declare that what
I claim is
1. Protecting the operatives engaged in curing and otherwise treating water-
proofed fabrics from noxious fumes by arranging and inclosing the machinery or
parts of machinery in the manner herein set forth or in an equivalent manner.

page_text: 2. The combination with a machine or parts of a machine for curing and other-
wise treating waterproofed fabrics of an outer casing a, substantially as and for
the purposes herein described and as illustrated by the Drawings annexed.
3. The use and application of a fan or ventilating shaft in combination with a
casing or separate chamber inclosing the machinery or parts of machinery employed
in curing, or curing and treating with farina, or other substance, waterproofed
fabrics, substantially as herein set forth for the purpose specified.
