I ELIE LAMY of Evreux, Eure, in the republic of France, Spinning Mill
Manager do hereby declare the nature of this invention to be as follows:-
My invention consists in improvements in the method of and apparatus for
transporting raw cotton to the machinery for working it in such a manner that
it is dried during its passage in a current of hot air whereby it can be cleaned
without. weakening it and be arranged into tufts or flocks ready for the beating
operation.
My method and my apparatuses allow of easily effecting the mixing of cotton,
of removing a part of the heat from the boiler and engine houses; of heating
factories by the heat of the current of air and of diminishing the risk of fire.
For this purpose I employ a pipe drawing hot air from the boiler or engine
houses into a receiver under a blower which takes this hot air and forces it into
the apparatus which receives at the same time the hot air and the cotton. The
cotton enters at the top passing between two rollers covered with leather and the
current of hot air enters below these two rollers and thus draws the cotton into
the cage of the apparatus which is contracted as it extends forward. Extending
from the cage is a pipe in which circulates the hot air and the cotton. Both are
thus carried to a distance and the cotton is distributed to the machines for working
it whilst the hot air can be employed for heating purposes.

I ELIE LAMY, of Evreux, Eure, in the republic of France, Spinning Mill
Manager, 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 :-
My invention consists in improvements in the method of and apparatus for
transporting raw cotton to the machinery for working it in such a manner that
it is dried during its passage in a current of hot air whereby it can be cleaned
without weakening it and be arranged into tufts or flocks ready for the beating
operation.
My method and my apparatuses allow of easily effecting the mixing of cotton,
of removing a part of the heat from the boiler and engine houses, of heating
factories by the heat of the current of air, and of diminishing the risk of fire.
In order to enable the invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 is a plan
and figure 2 is a longitudinal section of a suitable construction of apparatus for
carrying out my invention. Similar letters in all the figures represent similar parts.
My invention consists of four principal parts, videlicet;
1. A receiver A receiving hot air from boiler or engine houses by means of a
pipe.
2. A blower B placed above the said receiver drawing in the hot air in order to
force it into the apparatus properly so called.
3. The apparatus properly so called C. C. which receives the hot air and the
cotton at the same time. The cotton enters at the upper part and passes between
two rollers a and b, covered with leather. The current of hot air passes under the
rollers and draws the cotton with it into the cage of the apparatus C which is
contracted as it extends forward.
A pipe D extends from the apparatus and carries to a distance the hot air and
the cotton in order that they may pass through one of the openings F, F', formed
in this pipe over the receptacle for receiving the mixture.
The operation is as follows:-
Cotton is introduced into the machine by hand or by means of an opener
(ouvreuse) and passes between the two rollers a and b, covered with leather which
compress it. The cotton is carried by the current of hot air from the blower B
into the pipe D and' deposited where required. The blower is fed with hot air
from boilers or in engine houses. This hot air in carrying along the cotton beats
it by projecting it violently against the walls, cleans it, opens it, dries it during
its passage and then discharges it into the compartment in which the mixture
takes place.
By thus taking the hot air from boilers and engine houses through a pipe by
means of the blower a very notable lowering of the temperature is effected in such

page_text: places which are generally too highly heated. This hot air is then. discharged with
the cotton into the chamber in which the first mixture is effected. The cotton can
be afterwards taken by the same means and discharged into the beating chamber.
The hot air which is introduced raises the temperature of the factory and feeds the
blowers of the beaters at the same time.
The advantages of this invention are as follows:-
1. The transport of the cotton delivered into the machine at E as above
described.
2. Drying and cleaning the damp cotton without deteriorating it.
3. Arranging the cotton in tufts or flocks ready for the beating operation.
4. Allowing of making mixtures of "opened" cotton.
5. Lowering the temperature of boiler and engine houses.
6. Heating factories by utilizing heat which has hitherto been lost.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The means herein described of transporting cotton in factories by means of a
current of hot air.
2. The combination of pipes and receivers above described with a blower. for
effecting the transport.
3. The use of a blower for forcing the hot air under two feeding rollers supplying
the cotton to effect its transport.
4. The employment of hot air drawn or not from boiler or engine houses and
put in movement by means of a blower for drying, opening and cleaning the cotton
during its transport.
