I, DANIEL EHRLICH of Csengery Gasse 53, Budapest, in the Empire of Austria
Hungary, Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention has for its object a washing machine, by means of which, with very
little force, linen and the like can be washed quickly and efficiently.
In an outer case is contained the washing chest made of sheet zinc, enamelled iron
wood or any other suitable material. It has a cylindrical or round shape and its wall
is vertically corrugated. The bottom is deepened towards the centre and likewise
corrugated in such a manner, that the ribs converge towards the centre. The bottom
is provided with a hole in the centre, into which is placed a pipe provided with a cock
and serving for letting out the dirty water.
Within the washing chest, that is to say on the inner side of the lid thereof is
mounted a round disc provided with blunt depending arms, which are diminished
towards their extremities. The disc, therefore the arms, fixed to the same, are set
in to and fro movement by a mechanism provided on the lid of the box in the
following manner: The shaft of the arm disc carries a toothed pinion gearing into
a rack guided on the lid of the case; this rack is operated through a connecting
link by a crank on the main shaft so that when the latter revolves, the rack is
reciprocated, and the arms moved back and forth in the liquid. The time having
been ascertained in which linen etc. is completely cleansed in this machine, a bell may
be arranged to be struck by a hammer after the requisite number of revolutions of
the mainshaft, a worm on the latter operating through a train of wheels the hammer
of said bell.

page_text: manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention relates to washing machines and its object is to construct a machine
in which linen and the like can be expeditiously and effectively washed with exercise
of comparatively little force.
Referring to the accompanying drawings
Fig. 1 is a side elevation.
Fig. 2 a plan, and
Fig. 3 a part sectional front elevation of the improved machine.
a is a frame work of wood or other suitable material adapted to support the
receptacle 6 and other parts hereinafter described. b is the receptacle in which the
washing is performed, it may be made of sheet zinc, galvanised or enamelled iron,
wood or any other convenient material. The general shape of the receptacle b is
cylindrical, but the bottom thereof is deepened towards the centre and is corrugated
or ribbed, the ribs or corrugations converging towards the centre, the sides of the
receptacle b are likewise vertically corrugated or ribbed. In the centre of the bottom
of the said receptacle is an outlet provided with a cock for letting out the dirty water
therefrom.
The receptacle b is covered by a hinged or removable lid; this lid may be
rectangular as shown in Fig. 2, hinged to one side of the frame a and supported by
a rebate around the frame. A shaft passes perpendicularly through the lid centrally
above the receptacle b and carries below a disc or frame c having fixed to it a suitable
number (for instance three) of blunt and tapered arms d projecting downward into
the receptacle. The shaft aforesaid carries above the lid a toothed pinion n gearing
with rack teeth m provided on a prismatic bar guided in a suitable bed fixed on the
lid. A longitudinal slot is made in the bed and a wrist pin is fixed to the back of
the rack to project through said slot. The wrist pin is connected by rod k with a pin
or crank i said crank being carried by shaft journalled in bearings fixed to the lid.
The shaft carries at its outer end a spur wheel 9 adapted when the lid is closed to
gear with a spur wheel fon a shaft journalled in the frame a, the said shaft carrying
a fly wheel e having a crank handle thereon, whereby it may be turned by hand.-
The linen, water etc. being placed in the receptacle b, the lid is shut down, and the
crank handle turned, this causes the rack m to move back and forth in its guide bed,
and rotate the plate c with arms d alternately in the one or other direction. The arms
move the linen etc. about in the receptacle, rubbing it against the corrugated sides and
agitating the contents of the receptacle so that the linen is washed in a very short space of
time, generally about eight minutes. Since the washing of the linen is substantially
proportional to the amount of movement and agitation in the receptacle b, that is to

page_text: say to the number of revolutions of the plate c, a signal is provided to give notice
when a certain sufficient number of revolutions has been made. To this end, a worm
'thread p is arranged on the shaft h the same gearing with and actuating a train of
wheels r.
The last wheel of the train carries a pin adapted to abut against the
hammer levers of a signal bell t, so that the lever is deflected and the bell sounded
when the desired number of revolutions is completed.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:
In washing machines:
1) The combination with a receptacle 6 having ribbed or corrugated sides and a
centrally depressed bottom with converging ribs or corrugations; of a rotary disc c
having arms d substantially as set forth.
2) The combination of a receptacle b, a lid thereto, a rotary disc c having arms d,
a toothed pinion n on the shaft of said disc, rack m, bed 7 therefor, connecting rod k
and crank i substantially as set forth.
3) The combination with a receptacle for linen etc., and a rotary device therein, of
a worm on the shaft operating said device or otherwise in connection therewith, a
train of wheels r, levers and signal bell t for the purpose set forth.
4) The combination substantially as set forth of a frame work a a shaft, having
toothed wheel and fly wheel e with crank, journalled in said frame work, a receptacle b
supported thereby, a lid hinged to said frame work, a rotary agitator journalled in
said lid, a pinion n and rack m, a perforated bed plate for said rack, a wrist pin on
said rack, connecting rod k, crank i, shaft h and toothed wheel g on said shaft.
