page_text: We, ERNST LOMMATZSCH and BERTRAM TAUERSCHMIDT, Manufacturers, of Plauen,
in the kingdom of Saxony, do hereby declare the nature of this invention, to be
as follows:-
The invention chiefly comprises an iron trough or receptacle containing either
several drums, formed of laths, the said drums being fixed to radial arms mounted
on a central shaft and rotating in the above receptacle, or two concentric drums,
the space between them being divided by partitions. This first receptacle is
connected with one or more other receptacles by means of convenient pipes and
& three way cock for emptying the liquid from the first receptacle into the others
or vice versa.
The cloth etc. to be cleaned is placed in the drums contained in the first
receptacle which is half filled with benzine; the drums are caused to revolve, so
that the cloth is agitated in the benzine. When the washing is sufficiently
advanced, the benzine is drawn off into the second receptacle or set of receptacles,
the drums being again caused to rotate in order to shake out the benzine which
still adheres to the cloth. Fresh benzine is then placed in the first receptacle, and
the process is repeated, after which the cloth is removed from the apparatus in an
almost dry state.

We, ERNST LOMMATZSCH, and BERTRAM TAUERSCHMIDT of Plauen in the
German Empire, Manufacturers, 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 to the cleaning of articles or pieces of cloth by benzine
and has for its object to enable the whole process of cleaning to be performed in
one vessel and to perform the said process with more economy than heretofore.
Referring to the accompanying drawings showing my apparatus
Fig. 1 is a sectional elevation thereof.
Fig. 2 a sectional end view of Fig. 1.
Fig. 3 is a sectional elevation of a modified form of apparatus.
Fig. 4 a sectional end view of the last.
A is a tank, preferably of cylindrical form, in which the cleaning of the cloth
takes place, B1 B2 B3 B are drums, of which there may be any convenient number,
mounted on a central shaft C and revolving therewith. D D¹ are concentric drums,
the space between which is separated into chambers by the partitions c; these
serve as an alternative construction in place of the drums B₁ B* B* B*. These
drums are so constructed, preferably of wooden rods, permitting the liquid to easily
pass into and out of the drums. E is a jacket surrounding the tank A and serving
to heat the latter, when said jacket is filled with steam, hot air.or water through
the pipe g. F shows a tubular heater, placed inside the tank A, which heater may
take the place of the jacket E serving the same purpose as the latter. G is a
condenser of usual construction for condensing and recovering the vapour of
benzine formed during the process, for which purpose said condenser is connected
by pipes h h¹ to the tank A above and below and adapted to be separated by the
cock 2.
A³ A² are tanks for storing the benzine, connected to the lower part of the
tank A by a pipe with three-way cock b, and to the upper part of the said tank A
by pressure-compensating pipes a and also by means of the pipes d with three way
cock to a pump, for emptying them into the said tank A.
The cloth etc to be cleaned is placed in the drums B¹ B' B³ B' or, as the case
may be in the space between the concentric drums D D¹-portions of the same being
hinged to admit of the introduction of the cloth. The tank A is closed and the
cock fopened so as to enable the benzine to be pumped into the tank A from one
of the tanks A³, until the tank A is about half full, the cocks b being closed. The
shaft C is then revolved so that the drums carry the cloth alternately into and out
of the liquid. When the cleaning is sufficiently advanced, the cock b is opened so
as to enable the liquid in A to run into the second tank A, the air in the said tank
being displaced through the pipe a into the tank A. The drums are now briskly
revolved and, the adhering benzine, shaken off, being also partly vaporised. Fresh
benzine is now pumped in from the first tank A and the washing continued,
after which the said benzine is drawn off into the second tank A' and the drums

page_text: revolved in the empty tank A until the cloth is almost dry. To assist in the
drying, the jacket E or tube heater F is heated as before described, and the benziue,
remaining in the receptacle and adhering to the cloth is vaporised, the vapour
passes into the tube through the cock i and is condensed in G, returning to the
tube just above the three-way-cock b which conducts it to either of the tanks A A³
as may be desired. This heating will be found very desirable in the cleaning of
cloth which is much stained, since the action of the benzine is thereby assisted.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare, that what we
claim is:
In apparatus for cleaning cloth
1.) The tank A for receiving the cloth to be cleaned in combination with
tanks A connected therewith by pipes a and three-way-cock b substantially as
described.
2.) The tank A in combination with tanks A' pipe a and three-way cock bin
combination with pipes d three way cock f and pump H substantially as and for
the purpose described.
3.) The combination with tank A of jacket E and pipe g substantially as and for
the purpose described.
4.) The combination with tank A of a condenser G connected thereto by
pipes h h substantially as and for the purpose set forth.
5.) The combination with the tank A of drums B1 B2 B3 B' mounted on a
common axle C adapted to revolve in the said tank substantially as and for the
purpose described.
6.) The combination with the tank A of concentric drums D D¹, the space
between, which is divided, by longitudinal partitions c substantially as and for the
purpose described.
