PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drying Cloth or other Material.
I, WILLIAM HUTCHINSON of Weaste, Salford, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows.
This invention relates chiefly to that class of machine constructed with a single
cylinder for drying cloth subsequent to bleaching and preparatory to finishing
though applicable to any drying process during the bleaching finishing or dyeing of
cotton or other cloths.
The apparatus is constructed with a single cylinder mounted upon any suitable
framing and constructed with a light frame work of arms or the like. The periphery
is formed of a pipe coiled round and round and divided into sections. The several
sections of the pipe communicate with, or are connected with, a hollow spindle.
The spindle is divided either longitudinally or transversely with a diaphragm into
two compartments. Through one of these compartments steam enters and through
the other the water of condensation escapes the water which condenses in the pipes
gradually falling down as the cylinder rotates. The cylinder is rotated by means
of a cog wheel and suitable gear or by other driving device commonly applied to
such machines.
The cloth is caused to pass round the periphery of the cylinder as it rotates and
is wound upon rollers as it leaves the cylinder. A fan is placed to rotate in close
proximity to the surface of the travelling cloth to cool it before being rolled.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Drying Cloth or other Material.
I, WILLIAM HUTCHINSON, of Weaste, Salford, in the County of Lancaster,
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 relates chiefly to that class of machine constructed with a single
cylinder for drying cloth subsequent to bleaching and preparatory to finishing
though it may also be applied to machines where a number of cylinders are employed
and to any drying process during the bleaching finishing and dyeing of cotton or
other cloths.
It consists essentially of a cylinder or drum constructed with a steam pipe or pipes
coiled round the periphery and communicating with a central hollow axle through
which the steam enters the pipes and through which the water of condensation
escapes.
It will be fully described with reference to the annexed drawings.
Fig. 1, is a sectional side elevation
Fig. 2, front elevation in section and
Fig. 3, sectional plan of hollow axle.
The cylinder A is constructed of a light metal frame work B mounted on a
central axle C with an outer cylindrical surface D of sheet metal tinned or coppered,
lying between the two outer rims of the frame work B. On the under or inner
side of the outer cylindrical surface D and in close contact therewith are placed a
number of steam-pipes E coiled round and round the periphery and lying closely

page_text: side by side. The steam pipes E are divided into a number of lengths or sections
the extreme ends of each length or section being connected to the hollow axle C.
The pipes E may either be circular or flat in cross section.
.
The hollow central axle C is divided into two compartments by a diaphragm e
preferably placed as shewn diagonally across the interior. The two compartments
thus formed have each a nozzle or opening one through one end of the axle and the
other through the other end thereof. The steam enters through one end of the
axle and the water of condensation escapes through the other.
The ends e of the pipes E are connected to the steam side of the diaphragm c of
the hollow axle C and the ends e¹ of the steam pipes to the chamber at the other
side of the diaphragm. The steam passes up into the pipes E through the ends e
and as the cylinder rotates the water of condensation gradually falls down the
ends to the centre and escapes.
The cylinder A is preferably rotated by a spur wheel F which gears with teeth
placed round the rim of the frame-work B at one side or it may be actuated by any
other suitable driving device commonly applied to such machines.
The invention may be applied to smaller cylinders where a number are used
together in one machine.
The cloth G is fed to the cylinder over an ordinary cloth stretching roller H and
is caused to pass round almost the entire periphery of the cylinder as it rotates.
If desired a fan may be placed in close proximity to the surface of the cloth after
it has left the cylinder to cool it before being rolled or bundled.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I wish it to be understood that I
am aware that drying machines with a single cylinder have been used, and I do not
wish to claim the use of a single cylinder, but I declare that what I claim is :-
:-
1. A drying machine constructed with a single cylinder the periphery of which
is heated by a series of steam pipes coiled round and round the periphery substantially
as described.
2. A cylinder for drying cloth having one two or more sets of steam pipes coiled
round the periphery and a hollow central axle divided into two chambers with one
of which the respective ends of the steam pipes connect substantially as and for the
purpose described.
