Improvements in Washing Machines.
We, PAUL UNGERING, Mechanician, and JAKOB UNGERING, Mechanician, both
of Pannofen Strasse 104, Cleve, in the German Empire, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and claimed in and by the following statement:-
Many of the washing machines made in more recent times are constructed
so that inside one of the boxes containing the washing and the soap-suds, a
dolly is made to rotate alternately to the right and left, and so communicates
the action necessary for proper washing.
The mechanisms which hitherto have been employed to produce this right and
left rotation of the dolly all have the quality of depending absolutely and
entirely on the good will of the operator, and it may even be doubted whether
this action is really given in the proper way inasmuch as it is intermittent and
depends on the moving backwards and forward of a lever.
This is in the nature of things a great objection to these washing machines
and will be removed by the use of the present invention in which the alternately
rotating action of an axle carrying the dolly is produced by a rack working into
a pinion wheel on the axle and actuated by a crank.
The right and left rotating action is strictly regulated by the throw of the
crank and cannot be limited at pleasure by the person who operates the machine.
The action of the machine is thus quite independent of the special handling
of the person working it.
In the accompanying 'drawings is shown a washing machine of this kind
provided with the improved action.
Figure 1 shows a washing machine in vertical section.
Figure 2 shows a side elevation of the same.
Figure 3 shows a plan elevation of the same.
On the box a which receives the material to be washed, which is provided
on its inner side with corrugations, and which serves as a stand for the mechanism
of the washer, is a cover c hinged at d. This cover c carries the driving
mechanism, which consists of a fly wheel f affixed to the end of the fly wheel
axle g. On the other end of this axle is a toothed wheel which works into the
tooth wheel. The axle of the wheel bears at its opposite end a crank m,
the free arm of which is connected by a rod n with a rack o which is thus given
a reciprocating motion on the turning of the fly wheel f. The rack o works
into the pinion wheel which is fixed on the spindle which carries the
dolly.
The reciprocal action of the rack will thus cause the alternate right and left
rotation of the dolly. The dolly spindle is provided with a spring (pressing
it down) so that the dolly may adapt its height to the level of the washing (in
the box), for this purpose the spindle g works freely up and down in the
pinion wheel ? and both are of square or other conveniently shaped section.
To this explanation of the working of the washing machine it may be added,

page_text: that it is provided with a steam or vapour apparatus t, the purpose of which is
to keep the washing in a continuous state of warmth.
Further, the apparatus may be combined in any suitable way with a wringing
machine, not shown in the drawing.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is:-
Improvement in washing machines consisting of an arrangement by which the
rotation of a fly wheel (or driving) axle causes by means of a crank mechanism
producing a reciprocating action in a rack and pinion wheel, a right and left
alternate rotation of a spindle carrying a dolly, substantially as described.
