COMPLETE SPECIFICATION filed by the said Eugène Pasquier at the
Office of the Commissioners of Patents with his Petition and Declaration
on the 23rd May 1859, pursuant to the 9th Section of the Patent Law,
Amendment Act 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I; EUGÈNE
PASQUIER, Mechanic, residing at Reims, Hinemar Prolongée Street, Marne,
in the Empire of France, send greeting.
WHEREAS I am in possession of an Invention for "APPARATUS FOR DRYING
WOOL AND ALL FILACEOUS MATTERS," and have petitioned Her Majesty to grant
unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn Declaration that I am the true
and first Inventor thereof.
NOW KNOW YE, that I, the said Eugène Pasquier, do hereby declare
the following Complete Specification under my hand and seal fully describes
and ascertains the nature of the said Invention, and the manner in which the
same is to be performed, reference being had to the accompanying Drawings,
that is to say:-
Every person who has been engaged in the manufacture of wools, knows

page_text: what difficulties there are in drying them properly after washing or dying
without subjecting them to a temperature too high, and consequently destroy-
ing the strength, the pliancy, and the beauty of the filaments.
From repeated experiments I have found that the machines at present
employed have much that is objectionable; now the object of the present
Invention is to supply the deficiencies, at the same time preserving the
inherent properties of the different materials subjected to it, and also to greatly
diminish the size of the machines and expense occasioned by their employ-
ment, my apparatus producing twice as much as the best machines known to
this day.
The accompanying Drawings represent my new apparatus in vertical
projection seen externally, the shape can be altered more or less in length
and height according to the number of stories desired. The framework A of
the joints is of cast iron, or ribs of cast iron, or iron lined inside with sheet
iron. The supports or brackets B are placed at each end and side to receive
the cylinders, upon which is disposed the wire gauze linked together and
without end, this wire gauze is of special manufacture, which I reserve as my
exclusive property. This wire gauze forms as may be seen, the different
stories placed one above another, so that the matters which have passed
through one part fall on another, which draws it the contrary way. As many
of these stories can be put on as the importance of the apparatus necessitates.
The materials to be dried being thus turned several times are conducted to the
bottom of the apparatus & are taken out in a suitably dry state without being
exposed to a too high temperature. On one side the axles or shafts of the
cylinders are furnished with a cog wheel C gearing with an endless screw E,
fixed on a vertical shaft D, alternating on the side where the wheels gear with
the screw E, to give the contrary movement to each wire gauze. The shaft D,
which acts upon the wire gauze is moved by a flat plate or disk fixed on a
horizontal beam, put in motion by the motive power; this disk by its action
on a roller or pulley adapted to the shaft D, and ascending or descending for
the purpose of approaching or receding from the centre of the disk allows a
proportionate speed to be given according to the time required for drying.
To dry well and quickly and in case of insufficiency, two ventilators placed
outside or inside, either at the top or bottom of the apparatus will produce a
double effect in drawing up the damp air and sending it to the bottom through
tubes warmed by steam or hot air from a warming apparatus placed at the
bottom of the machine so as to dry it before passing through the different
layers of drying matter. It must be understood that these ventilators can be
used separately, either for drawing up or introducing hot air; if it be required

page_text: to suppress the aspiration of the ventilators, one or two openings can be made
at the top of the roof with pipes answering the purpose of chimneys so as to
let the air escape already charged with steam. The ventilators can also be
replaced by several fans placed between the furnace and the first wire gauze,
and producing nearly the same effect.
Having thus described my Invention, and the manner in which the same
is or may be carried into effect, I which it to be distinctly understood that I do
not confine myself to the precise details above described, as the same may be
varied or modified without departing from the principle of action thereof;
what I claim is the system and arrangement of apparatus as above described
and shown in the accompanying Drawings, together with the right of manu-
facture of the wire gauze specially required for the apparatus, and also the
arrangement of ventilators for the introduction of hot air, and the removal of
damp air.
In witness whereof, I, the said Eugène Pasquier, have hereunto set my
hand and seal, this 23rd day of May, in the year of our Lord One
thousand eight hundred and fifty-nine.
EUGENE PASQUIER. (L.S.)
