PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cooling Cloth.
We ALFRED ARMITAGE of Newtown and TOM CARTER of Taylor Hill both of
Huddersfield in the County of York, Engineers, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to apparatus employed in forcing a current of cold air upon
or through cloth which has become heated in the process of tentering.
To carry out our invention we pass the cloth as it leaves the tentering machine over
or under a roller into a flat rectangular box in which the cooling operation is
performed. Across each side of this box and at right angles with the line of direction
in which the cloth is caused to travel, are air passages connected with a revolving
fan, and these air passages are connected by tapering slits or openings with the interior
of the box, opening at each side of the cloth which is drawn through the centre of the
box, and a current of cold air is blown through the slits upon each side of the cloth
thereby cooling it as it passes through the box on its way from the tentering machine
to the cutting table.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cooling Cloth.
We ALFRED ARMITAGE of Newtown, and TOM CARTER of Taylor Hill, both of
Huddersfield in the County of York, Engineers, 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 :-
Our invention relates to apparatus employed in forcing a current of cold air upon
or through cloth which has become heated in the process of tentering.
To carry out our invention we pass the cloth, as it leaves the tentering machine,
over or under a roller into a flat rectangular box in which the cooling operation is
performed. Across each side of this box and at right angles with the line of
direction in which the cloth is caused to travel, are formed air passages connected
with a revolving fan, and these air passages are connected by means of tapering slits
or openings with the interior of the box, opening at each side of the cloth which is
drawn through the centre of the box and a current of cold air is blown through the
slits upon each side of the cloth thereby cooling it as it passes through the box on its
way from the tentering machine to the cuttling table.
In order to enable this invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which,
Figure 1. represents a plan partly in section of the cooling box with air supply pipe
and air passages, and Figure 2 a sectional elevation of the cooling box, the fan for
supplying cold air, and a portion of the front of a tentering machine.
Similar parts are referred to by similar letters in both drawings.
The cloth passing from the tentering to the cooling machine is represented at A A,
which cloth passes over. or under the rollers NN which are either mounted upon
brackets fixed to the cooling box, or to other convenient positions.
The cloth passes straight through the cooling box, which is provided with air
passages DD which communicate with the fan C by means of the pipe B. When
the air which has passed along the pipe B reaches the point F it is divided by a

page_text: partition into two currents which supply the upper and lower air passages D D, thus
being divided into the two portions required to blow upon the two sides of the cloth,
the air then passes from the passages through narrow slits H H whence it is
projected upon each side of the cloth which is drawn through the cooling box.
The current of air is further divided by the resilient tongue E operated by the
thumbscrew G, in order that a properly regulated portion may pass to each side of
the box and be properly diffused over the surface of the cloth.
Doors J J open into the cooling box to enable the attendants to grasp the cloth and
pull it through when starting the operation.
The two front chain-wheels of the tentering machine are represented at K K, and
the frame or pillars thereof at L, the platform upon which the operator stands at M
and the cuttling rollers at O O.
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. For the purpose of cooling cloth which has become heated during the tentering
process, the employment of a rotary fan blowing cold air into a cooling box through
which the cloth passes, the cooling box being provided with air passages and slits
opening upon the cloth being cooled, all the various parts being constructed and
operated substantially in the manner described and as represented in the accompanying
drawings.
2. In apparatus for cooling cloth after it has passed the tentering machine, the
general arrangement and combination of the rotary fan, with the air passages and slits
in the cooling box, the regulating tongue, and the cuttling and other rollers, all
substantially as described and represented in the accompanying drawings.
Dated this Twentieth day of November 1889.
