PROVISIONAL SPECIFICATION.
Improvements in Drying Cotton, Woollen, and Linen Goods.
I LEONARD NOBLETT of 11 & 13 Houghton Street in the City of Liverpool Confec-
tionery Manufacturer do hereby declare the nature of this invention to be as.
follows:-
An improved means of drying cotton, woollen, linen or other baled goods either in:
bulk or parcel and damaged or otherwise, in vacuo by means of a vacuum box, chest,
or room. In such cases as shipwrecks, fires in warehouses and floods it happens that.
bales of cotton woollen or other goods become impregnated with water, which water
has to be removed by drying, either in the open air, or upon the floors of kilns, or
specially built drying rooms, all of which methods are slow in action and expensive.
My invention consists in drying cotton, woollen, linen or other goods of this class
including rags and waste, by placing them in a chest, room or box, heated by steam
or hot air or other known means, in which I maintain a vacuum until the necessary
quantity of moisture is extracted.
COMPLETE SPECIFICATION.
Improvements in Drying Cotton, Woollen, and Linen Goods.
I LEONARD NOBLETT of 11 and 13 Houghton Street in the City of Liverpool Con--
fectionery Manufacturer 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:-
:
In order to describe my invention in the clearest manner, I shall divide the goods.
to be treated into two classes; class 1, being goods such as raw cotton or wool such
as are tightly compressed into bales: class 2 being linen, woollen or cotton goods,.
commonly called Manchester goods which may be loose.
Referring to class 1, bales of raw cotton, wool &c. often become impregnated with.
water owing to immersion in the sea, or owing to the water used in extinguishing fires
in warehouses, and many other causes. The only known and applied method, for
evaporating such water, has necessitated the unbanding and breaking up of the bales,
and the spreading out of the materials of which they were composed, either on the
open fields, or upon kiln floors. By my invention such breaking up will be avoided..
Referring to class 2; cotton and linen goods commonly called Manchester goods,-
such as it may be necessary to dry in washhouses, hospitals or other large establish-
ments, by my invention will be dried in a more expeditious manner, and all risk of
singeing, or burning will be avoided, and during the process of drying, a thorough
disinfecting of the articles will take place. Attached are drawings of a suitable
apparatus for carrying out my invention.

struction,) or other apparatus by which vapours may be withdrawn, and the necessary
vacuum maintained within the chamber, e: are steam or other heating pipes, by which
the chamber, a, is heated.
In carrying out my invention, I remove the lid b, and run in the goods h, on a
trolly, or clothes horse; I then replace the lid and secure air tight by dogs : I then
heat by means of pipes e, and at once commence to extract the atmosphere, and vapour,
through pipe d.
Having now particularly described and ascertained my invention, what I
claim is :-
1st. The drying of bales of cotton, wool, or other packed goods; by placing them
in a chamber heated by steam pipes, in which chamber I maintain a vacuum until all
moisture is extracted, such drying being accomplished by this process without the
necessity for unbanding, or breaking up the bale.
2nd. The drying of loose cotton, or linen goods; by placing them in a chamber
heated by steam pipes; in which chamber I maintain a vacuum until all moisture is
extracted; the goods being at the same time dried, and disinfected, in the process of
drying.
3rd. The use of a box, or chest, or room, heated by steam pipes, in which a vacuum
is maintained, the said box, chest, or room, being used for drying raw cotton, wool,
linen, or other goods in bale.
4th. The use of a box, or chest, or room, heated by steam pipes, in which a vacuum
is maintained the said box, chest, or room being used for drying woollen, linen or
cotton goods loose.
