Improvements in Drying and Stretching Cotton or other Fabrics and
in Apparatus therefor.
We, HARRY EDWARD AYKROYD, of Glen Rosa, The Grove, Ilkley, in the
County of York, Dyer, and JESSE GRAHAM, of 92, Hollings Road, Bradford, in
the County of York, Engineer, do hereby declare the nature of this invention
to be as follows:
This invention has for its object a method of more efficiently drying and at
the same time stretching cotton or other fabrics, and it consists essentially in
passing them through or over a stentering or drying machine while enclosed

in a chamber constructed and heated substantially as hereinafter described.
also specially claim as our invention the apparatus. This latter consists essen-
tially of one or more rectangular iron or metal boxes connected directly into a
separate pipe or chamber where a partial vacuum is created and maintained by
means of a steam jet, water jet, pump, or fan. In the above mentioned rectan-
gular boxes are laid a number of metal pipes (the quantity depending on the
amount of heat required) perforated with small holes, which supply a mixture
of air and gas, which can (the box being made airtight by a cover of copper or
other metal being firmly bolted down to the said box, and an airtight joint being
made by means of red lead cement or any other material) by means of valves or
taps, be so regulated on the air and gas inlets, as to produce a perfect Bunsen
or blow pipe flame, thereby utilising the full heating power of the gas and
also ejecting the obnoxious gases out of the room into the outside atmosphere.
The rectangular boxes are preferably lined with asbestos, or any other non-
conducting material where the heat is not required, so as to stop the radiation from
the walls of the above mentioned boxes and pipes, and thereby concentrate all the
heat to the surface where it is required. The boxes are also fitted with sliding
windows constructed of transparent mica, so that the attendant, can see through
into the boxes, and therefore acts as a guide for the proper regulation of the
above said air and gas.

page_text: Leonards Road, Girlington, Bradford, in the County of York, Engineer, 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 has for its object a method of more efficiently drying and at
the same time stretching cotton or other fabrics, and it consists essentially in
passing them through or over a stentering or drying machine while enclosed in
a chamber constructed and heated substantially as hereinafter described. Our
invention also comprises the apparatus for carrying this method into effect.
The invention will now be described with reference to the accompanying draw-
ings in which:
Figure 1 is a sectional elevation;
Figure 2 a sectional plan, and
Figure 3 a cross section of the improved heating or drying apparatus.
Figures 4 and 5 are diagrammatic views in cross section and longitudinal
section showing the heating apparatus as applied to a stentering machine.
The heating apparatus consists essentially of one or more rectangular iron
or metal boxes A connected directly into a separate pipe or chamber B where a
partial vacuum is created and maintained by means of a steam jet C or a water
jet, pump, or fan.
In the above mentioned rectangular boxes A are laid a
number of metal pipes D (the quantity depending on the amount of heat required)
perforated with small holes, which supply a mixture of air and gas, which can
(the box being made airtight by a cover E of copper or other metal being firmly
bolted down to the said box, and an airtight joint being made by means of
red lead cement or any other material) by means of valves or taps such as F,
be so regulated on the air and gas inlets, as to produce a perfect Bunsen or blow
pipe flame, thereby utilising the full heating power of the gas and ejecting the
obnoxious gases out of the room into the outside atmosphere. The rectangular
boxes A are preferably lined with asbestos, or any other nonconducting material
where the heat is not required, so as to stop the radiation from the walls of the
above mentioned boxes and pipes, and thereby concentrate all the heat to the
surface where it is required. The boxes are also fitted with sliding windows G
constructed of transparent mica, so that the attendant can see through into the
boxes, and therefore acts as a guide for the proper regulation of the above said
air and gas.
The heating boxes described are adapted to be readily inserted in a stentering
machine for instance as shown at A in Figures 4 and 5 in such a way that the
fabric T is transported over their heating surfaces by chain gear S and a simul-
taneous drying and stretching effected as before stated.
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. The improved method of drying and stretching fabrics which consists
in applying heat to the fabric whilst in a stentering apparatus whereby the
drying and stretching is effected simultaneously and thereby in a more efficaceous
manner, substantially as herein before set forth.
2. Providing stentering or like stretching apparatus with one or more metallic
heating faces in proximity to the fabric, for the purpose of simultaneously drying
and stretching fabrics, substantially as herein before described.
3. The improved drying apparatus for fabrics, comprising one or more station-
ary metallic heating faces in proximity to which the fabric is adapted to be
drawn, and Bunsen or blow-pipe heating devices adapted to heat said faces,
substantially as herein before described.
4. In drying apparatus for fabrics, the construction of metallic heating faces
in the form of one or more boxes, containing Bunsen or blow-pipe heating devices,

page_text: said boxes being air-tightly closed and connected with a chamber or pipe in
which a partial vacuum is maintained, with the object of obtaining a perfect
Bunsen or blow-pipe flame, and ejecting obnoxious gases substantially as
described.
5. The improved apparatus for drying and stretching fabrics, constructed and
operating as a whole, substantially as herein before described with reference to
the drawings.
