Improvements in Washing Machines.
We, HEINRICH MUNDLOS, and RUDOLPH ARENDT, trading together as
H. Mundlos and Company, of Magdeburg, in the German Empire, Manufacturers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in washing machines, whereby the
washing of clothes, or other articles, can be more efficiently and expeditiously
performed than heretofore, and in a manner somewhat analogous to that of
washing, by hand, with a dolly.
According to our invention the washing machine consists, by preference, of a
hexagonal or other polygonally-shaped vessel, lined with corrugated metal, and
provided with a tight fitting cover or lid, through which passes a vertically
arranged shaft carrying, at its lower or inner end, a dolly" or disc furnished with
projecting pieces or fins, and this "dolly" receives a simultaneous semi-rotary
and reciprocating motion during the washing operation by any suitable meaus, as
for instance by a lever handle fixed to one end of a horizontally arranged axis
carrying at its lower end a bevil wheel gearing with a bevil pinion mounted loosely.
on the said vertical shaft. This bevil wheel is provided with a pin or stud to
which is connected one end of a stirrup-piece or crank, while the other
end of said stirrup-piece or crank is connected to the vertical shaft, and
the bevil pinion is provided with a sleeve furnished with a feather entering
a longitudinal groove in the vertical shaft. Thus when the lever handle
is rocked by the operator, the "dolly," through the intervention of the stirrup-
piece or crank, is caused to rise and fall, and at the same time, through the
intervention of the groove and feather, to partially turn about its axis, and thus
to operate upon the articles being washed.
In a machine constructed according to our invention the mechanism is situated
outside the washing machine, and is thus entirely away from contact with the clothes
or other articles, so that all chance of these latter becoming discolored is avoided,
and the mechanism prevented from getting rusty.

Improvements in Washing Machines.
We, HEINRICH MUNDLOS and RUDOLPH ARENDT, trading together as
H. Mundlos and Company, of Magdeburg, 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, reference being had to the accompanying drawings and to the
letters and figures marked thereon, that is to say :-
This invention relates to improvements in washing machines, whereby the
washing of clothes, or other articles, can be more efficiently and expeditiously
performed than heretofore, and in a manner somewhat analogous to that of
washing by hand with a “dolly.”
"

page_text: According to our invention, the washing machine consists, by preference, of a
hexagonal or other polygonally shaped vessel lined with corrugated metal and
provided with a tight fitting cover or lid, through which passes a vertically
arranged shaft carrying, at its lower or inner end, a "dolly," or a disc furnished
with projecting pieces or fins; and this "dolly" receives a simultaneous semi-
rotary and reciprocating motion during the washing operation by any suitable
means, as, for instance, by a lever-handle fixed to one end of a horizontally
arranged axis carrying at its other end a bevil wheel gearing with a bevil pinion
mounted loosely on the said vertical shaft. This bevil wheel is provided with a
pin or stud to which is connected one end of a stirrup-piece or crank, while the
..other end of said stirrup-piece or crank is connected to the vertical shaft, and the
bevil pinion is provided with a sleeve and furnished with a feather entering a
longitudinal groove in the vertical shaft. Thus, when the lever-handle is rocked
by the operator, the dolly, through the intervention of the stirrup-piece or crank,
is caused to rise and fall, and, at the same time, through the intervention of the
groove and feather, to partially turn about its axis, and thus operate upon the
articles to be washed.
In a washing machine constructed according to our invention, the mechanism is
situated outside the machine, and is thus entirely away from contact with the
clothes, or other articles, so that all chance of these latter becoming discoloured
thereby is avoided, and the mechanism also prevented from getting rusty.
In order that our invention may be readily understood we proceed to describe
the same fully with reference to the accompanying drawings, in which :-
Fig. 1 is a transverse section on the line 1, 1, and Fig. 2 a plan, of a washing
machine constructed according to our invention.
Fig. 3 is a longitudinal elevation, partly in section, of the means or mechanism
employed for operating the "dolly.'
"
a is the body of the washing machine consisting of a suitably shaped wooden
vessel provided with legs a', and having a hinged lid or cover . This lid is
furnished with a flange b', and just within the mouth of the body is a rim or
bead a², so that when said lid is closed a sufficiently tight joint is formed to prevent
splashing over of the water during washing.
Firmly bolted to the outside of the cover is a casting c, constituting a bearing
for the horizontal shaft d and the vertical shaft e.
The horizontal shaft d has a socket dat its outer end, for the reception of a
detachable wooden handle d', and at its inner end a bevil wheel d' gearing with a
bevil pinion mounted loosely on the vertical shaft e. To the bevil wheel d³ is
pivotted, by the pin or stud f¹, one end of a crank or stirrup-piece f whose other
end terminates in a curved shoulder, having an elongated hole through which
the vertical shaft e passes. This crank or stirrup-piece is shaped as shown at
Fig. 1 so as to encompass the horizontal arın c¹ of the casting c, and be free to
partake of its various movements without impinging against said arm.
The vertical shaft e carries at its lower end, the dolly or disc g, having pro-
jecting pieces or fins g', and this shaft is formed with a longitudinal groove e' with
which a feather e³ (Fig. 3) projecting from the pinion engages and transmits the
rotary motion to the vertical shaft without interfering with the free movement of
said shaft in a longitudinal direction. As will be seen on reference to the drawings,
the curved shoulder comes immediately beneath a collar which is fixed to the
vertical shaft by a pin h¹ so that when the bevil wheel dis caused to oscillate by a
to and fro movement given to the handled by the operator, in the direction of the
arrows in Fig. 1, the crank or stirrup-piece f assumes the position shown in dotted
lines (Fig. 1) when the handle is moved to the left, and a corresponding position on
the other side of the vertical shaft, when the handle is moved to the right. By
continuing this to and fro movement of the handle, the crank or stirrup-piece is
caused to rise and fall, and thus transmits a rectilinear movement to the vertical
shaft through the curved shoulder f and collar h, while said vertical shaft also
receives an oscillatory movement through the bevil wheels and . In this

page_text: manner the dolly is made to perform a compound movement consisting of a simul-
taneous reciprocating rectilinear movement and reciprocating rotary movement,
which is a somewhat similar movement to that performed by an ordinary hand-
operated dolly. By varying the extent to which the handle is rocked, the
amplitude of this compound movement of the dolly can also be more or less varied
at will.
Although it is not absolutely essential, we prefer to employ a spiral spring i,
arranged around the vertical shaft e, for the purpose of bringing the handle d³,
when released by the operator, into its vertical position, the upper end of said
spring bearing against the underside of the arm c¹ of the casting, and the lower
end against a collar i¹ carried by and moving with the vertical shaft. A sleeve j
surrounds.said spring and also serves to restrain the pinion e³ from longitudinal
movement on said vertical shaft e.
The interior of the vessel or body a of the machine may advantageously be lined
with galvanized corrugated metal, and the underside of the lid, as well as the
exterior of the dolly, may be covered with galvanized metal. A tap or cock k is
provided for drawing off the soapy water when desired.
The lid is likewise furnished with a fastening device l, which also constitutes a
handle for raising the lid, and projecting pieces m are provided upon the body which
act as stops to limit the extent to which the lid can be turned back and also to
support it when in its open position.
The machine may have a transverse rail n, which, by abutting against a
wall or other like surface will greatly aid in steadying the machine during
working.
In order to prevent the oil with which the mechanism is lubricated, from
trickling down the vertical shaft and entering the vessel and so soiling the clothes,
we provide said vertical shaft with a loose box o containing some absorbent
material which will readily soak up any oil that may run down said shaft.
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 :-
1. The improved washing machine in which a dolly, or disc furnished with pro-
jecting pieces or fins, is caused to receive a compound movement consisting of a
simultaneous reciprocating rectilinear movement and reciprocating rotary movement,
substantially as hereinbefore described.
2. The means or mechanism for imparting the compound motion to the dolly,
substantially as described and shown.
3. Our improvements in washing machines, substantially as described and shown
by the annexed drawings.
