Improvements in Washing Machines.
I, CARL STUTE, of No. 6 am Cleverthone, Hanover, in the Province of
Hanover, German Empire, Washing Machine Manufacturer, 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:-
My invention relates to a centrifugal washing machine, comprising a rotating
cylinder for the reception of the clothes to be washed, and a second cylinder
enclosing the first named for the reception of the lye and water.
Suitable means for introduction and removal of the clothes is provided, also,
means for rotating the inner or washing cylinder, and tubes carried by it, and
which said tubes serve as means for taking the water or lye or both, from the
lower part of lower and drum cylinder to the top of it, for the purpose as herein-
after described.
Figure 1 of the accompanying drawing represents a longitudinal sectional
elevation of a washing machine constructed according to my invention.
Figure 2 is a cross section of the same.
Figure 3 is a detailed side elevation, showing the part of the inner cylinder
provided with the door for the introduction of the clothes.
Figure 4 is a side elevation of the outer cylinder, showing the means for closing
the same.
'
Figure 5 is a cross sectional elevation of the outer cylinder.
Figure 6 is an end elevation of a portion of the inner cylinder.
Figure 7 is a longitudinal sectional elevation of the same.
Figures 8 and 9 are detailed cross sectional elevations of the outer cylinder,
showing the manner of securing the cover s.
Figure 10 is a corresponding longitudinal sectional elevation.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The inner cylinder w, constituting the washing cylinder proper, is provided with two
convex surfaces w¹, w¹, and two concave surfaces w³, w³, (see Figure 2). The convex
surfaces w¹, are formed by tubes r, a small space being left between each two of
these tubes. The ends r¹, of the latter are secured to the ends w3, of the washing
cylinder w, by means of short sleeves 72. Tubes r, are open at both ends and
project from the edge of ends w³, their centres being placed on the said edge or
about so. The portion of tubes r facing the inside of cylinder w, is provided in its
whole length with small holes *, (see Figure 7). To the ends 20³, there are secured
shafts which

may rotate in sleeves, supported by standards a. The sleeves h,
are provided with collars h', which are secured to the ends 6. Suitable pipes are
connected to the ends 61, for the introduction of lye, water and steam, for letting
out the water, and for escape of the vapours. These pipes are not shewn in the
drawings.
The opening in the cylinder b, through which the clothes to be washed are
entered, is closed by means of the closing cover s, provided with handles s', (see
Figure 4). The front edge of the cover s, may be pressed against an india-rubber
packing g', by tightening the screws, placed in a small bearing secured to cylinder b.
At the same time the angle iron ³, fixed to the rear edge of covers, is pressed
against another strip of india-rubber g³. In order to ensure a tight fitting at the
side edges, of the cover s, I provide two spring clips f, to the under face of
which there are secured the rubber strips 93, the latter may be pressed on the
covers, by tightening the screws, arranged similarly to the screws.
The washing cylinder w, is likewise provided with an opening to*, for the insertion

page_text: of the clothes, this opening being closed by means of a double hinged door or cover k,
which is locked by means of a rod similar to a sash-bolt (this rod is not shown on
the drawing).
I may also alter the construction of the washing cylinder by forming its entire
surface of tubes r.
The operation of the washing machine is as follows:-
The outer cylinder is turned in its bearing until the handles may be reached
easily. Hereafter the screws 2 and 3, are loosened and the cover s, opened by
pushing it upwards. Therefrom the inner and washing cylinder wo, is turned until
its door k, is opposite the opening in the outer cylinder 6 and then the door
is opened, and the inner cylinder w, is about half filled with the clothes to be
washed.
The outer cylinder bis then filled about to one third with soap and soda lye.
The door k and covers, are then closed by the means described hereinbefore, and
the outer cylinder b, is locked by any suitable means, so that it may not partake of
the rotation of the washing cylinder w. Then the latter is rotated by any
appropriate gearing, for instance in the direction indicated by the arrow on Figure 2,
and the clothes are carried up by the left hand convex surface w¹, w¹. The tubes r
constituting the lower concave surface w², being open at both ends, become filled
with lyc, and part of this lye is also carried to the top of washing cylinder w,
by the rotation of the same. In a certain position of the cylinder (varying according
to its velocity of rotation) the clothes fall by gravity on the lower convex
surface w', w¹, and having been previously wetted by the lye entering through the
perforations of the curved ends w³, they are cleaned by being thrown and rubbed
against the sides and ends of the cylinder w, and also by friction against each other.
At the same time the lye dipped out by the tubes r, is distributed in a spray
towards the interior through the small holes, and removes the dirt by rinsing, the
dirt flowing into the outer cylinder b, through the interstices between the tubes r.
After a certain time, the used lye and water is drawn off.
In
According to the direction in which the washing cylinder w, rotates, the clothes
are carried forward and upward by one or the other of the concave faces w².
order that the clothes may be washed thoroughly, it is preferable to reverse the
rotation of the washing cylinder w, after a few revolutions. By this means, and
by raising at the same time the temperature of the lye by heating, all dirt is
removed from the clothes. Then the used lye is drawn off from the outer cylinder b,
and warm water is let in; the alternate rotation of the washing cylinder w, is
started again, and thus the remainder of lye and soap is removed from the textile
fabrics, after which the soiled water is let off, and pure cold water let in, and the
clothes washed once more. Finally the clean and cool wash is taken out of the
washing cylinder w, through the cover s, and door k, and the machine is then ready
for the reception of the next wash.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First In a washing machine, or a centrifugal washing machine, comprising
essentially an inner rotatory washing cylinder, with convex and concave reticulated
or part reticulated surfaces and an outer enclosing cylinder or casing, wherein the
first named and washing and clothes cylinder rotates, substantially as and for the
purpose as described and set forth.
Secondly In a washing machine consisting essentially of an inner rotatory
cylinder, and an outer casing, the former having convex and concaved reticulated
and corrugated or undulating surfaces, or part convex and concaved, and part
reticulated, and part undulatory surfaces, substantially as and for the purpose as
described and set forth.
Thirdly: In a washing machine, forming the sides or parts of the sides of the
inner and working cylinder of open ended and inwardly perforated and separated

page_text: tubes or their equivalent, such as open troughs or the like, whereby the water and
lye is distributed and lifted, substantially as and for the purpose as described and
set forth.
Fourthly-In a washing machine, forming the sides of the inner and washing
cylinder, of open ended, and inwardly perforated tubes (or open troughs) and the
ends of perforated or openwork metal, substantially as described and set forth.
Fifthly In a washing machine, providing the outer casing with a curved sliding
door, as described and set forth.
.
Sixthly: In a washing machine, or a centrifugal washing machine, the construc-
tion, arrangement and combination of the parts, fittings and mountings, substantially
as described and illustrated.
