5 I, FRANZ WIRTH, of the Firm of Wirth & Company Patent Agency,
residing at Frankfurt-/-Maine (Germany) do hereby declare the nature
of the said Invention for "CERTAIN IMPROVEMENTS IN THE PROCESS OF
WASHING YARNS AND IN THE APPARATUS EMPLOYED THEREFOR," (a communica-
cation to me from John Albert Dold, Manufacturer, of Reutlingen,
10 Kingdom of Würtemberg, to be as follows:-
The Invention is designed for the purpose of washing cotton yarn,
whether in hank, skein, bobbin, or cop, without altering their forma-
tion for the purpose, and also whilst they are inert or stationary in one
5 ing expedites and economises the process of thoroughly and uniformly
position. The application of the improvements for the purpose of wash-
cleansing the yarn.

page_text: According to the first part of
of yarn
to be washed are suspended from and loaded by rods of iron or other
suitable metal, the whole of which are placed in a vessel or chamber and
then hermetically enclosed therein. This vessel or chamber is connected
on one side through the medium of a pipe with an
arrangement of 5
pumps, and on the other side with a pipe connecting the same with
a vat or receptacle containing the liquor or "ley" with which the yarn
is to be washed. At a point in this pipe between the closed chamber
to a given pressure so that when the chamber containing the yarn is 1
containing the yarn and the "ley" tub a valve is provided loaded up
exhausted by the pump so as to produce a vacuum therein the pressure
of the atmosphere on the "ley" or liquor in the vat will open the
valve so as to cause the liquor to be injected through the same into
the vacuum space containing the yarn to be washed, and thus is
enabled effectually to pass through and thoroughly wash every fibre of
the same.
After the process of washing is finished the receptacle containing the
yarn is opened, and the liquor discharged therefrom by means of the
pump previously employed for producing a vacuum; or a circulation of
the liquor for re-washing may be obtained by the use of the pumps
passing the same into the "ley" tub or receptacle; or the ejection of the
liquor may be caused by the pump forcing the liquor when used back
again into the tub.
The second portion of this Invention has for its object the washing
of cops as they are delivered from the mule spindles without the neces
sity of re-winding them, and consists in placing them on a perforated
corrugated plate, which forms the bottom of a receptacle connected
with the suction pipe of a pump. The cops to be washed are placed
in the grooves formed by the perforated corrugations of the suction
receptacle, which when so filled are covered with the "ley"
or wash
liquor which is poured or supplied to the corrugated receptacle contain-
ing the cops of yarn is sucked or drawn through by the action of the
pump, and so thoroughly permeates and washes every fibre of the yarn
composing the cops. The cops after being thus washed are
placed on
shelves or supports in a closed box or receptacle communicating direct
by means of a pipe with a fan. This pipe for a great portion of its
length before entering the box containing the cops passes through the
