Improvements in Dollies or Devices for Washing or Cleansing
Clothes and the like.
I, EMIL HARTUNG, of Untermarkt, Mülhausen i Thüringen, Germany,
Manufacturer of Iron-ware, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to a washing dolly or device designed to be rotated screw-
fashion into the washing or cleansing liquor or the articles or linen being washed
or cleansed being so constructed as when so rotated to catch and compress the air
and distribute it in a fine state of sub-division (throughout the washing liquor or
articles being washed); and when rotated sorew-fashion out from the washing liquor
or articles being washed to produce a suction of the air. This improved device
differs essentially from the ordinary washing plungers or "dollies" heretofore in
use which are only moved vertically up and down in the washing liquor or articles
being washed.
Fig. 1 of the accompanying drawings is a vertical section, partly in elevation,
and Fig. 2 is an underside view, shewing a dolly or device according to this
invention.
In the interior of the cone a there are arranged helical or screw-like sheet metal
vanes which, in the arrangement illustrated, are left-handed, but which may be
right-handed if preferred. These vanes serve to catch and compress air when
the washing device is rotated in a downward and suitable direction and to convey
such air under considerable and constantly increasing pressure into the washing
liquor or articles being washed; whilst when the device is rotated in the reverse
direction, the air will be powerfully sucked in from the washing liquor or articles
being washed. This has the effect of producing an intimate stirring or intermingling
of the washing liquor with air. This intermingling of the washing liquor, or articles
being washed, with small bubbles or vesicles of air quickly produces a thick soapy
lather whereby the articles under treatment are thoroughly washed and cleansed.
This mode of operation serves to essentially distinguish the washing dolly according
to this invention from the so-called air-dollies, inasmuch as the latter are always so
constructed as to execute only a vertical up and down motion, whilst the pockets or
double-cones provided in the cones of said air-dollies only exert a suction upon the air,
and transfer this air only to a very slight extent to the washing liquor or articles
being washed. The number of the spiral air-vanes in a dolly according to this
invention may vary according to the dimensions of the apparatus. The direction
of the vanes depends on the direction of movement it is desired to impart to the
washing cone whilst it is being screwed or rotated down into the articles being
washed. Thus, the apparatus illustrated must, when in use, be rotated with a
right hand motion, so that the several vanes b shall catch the air, and force it
towards the centre with a constantly increasing pressure, and then force it into
the washing liquor through the meshes and interstices of the articles being
washed.
In the screwing motion out of the washing liquor or articles being washed the
air on the contrary is sucked in.
In the construction shown, the handle-rod or shank terminates in a cylindrical
socket c of truncated conical shape. This socket extends partly through the

page_text: cone a (which is strengthened at its upper end by the jacket d)'and is soldered to
the upper part of the shell of the cone a, to the ring e, and also to the air vanes b.
In this manner there is provided a firm attachment between the cone a, the air
vanes and the handle-socket c, so that, when in use, the cone cannot become
disconnected from the handle, and great durability of the apparatus is ensured ;
which feature has been a seriously felt desideratum in the air-washing apparatus
heretofore in use.

Improvements in Dollies or Devices for Washing or Cleansing
Clothes and the like.
1. EMIL HARTUNG, of Untermarkt, Mülhausen i Thüringen, Germany,
Manufacturer of Ironware, 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 a washing dolly or device so constructed that when
rotated screw-fashion into the washing or cleansing liquor or the articles or linen
being washed or cleansed it will catch and compress the air and distribute it in a
fine state of sub-division throughout the washing liquor or articles being washed;
and when rotated screw-fashion out of the washing liquor or articles being washed
or cleansed it will produce a suction of the air in the reverse direction. The
improved dolly or device differs essentially from the ordinary washing plungers or
"dollies" heretofore in use, which are only moved vertically up and down in the
washing liquor or articles being washed..
Fig. 1 of the drawings filed with my Provisional Specification, is a vertical
section, partly in elevation and Fig. 2 is an underside view showing a dolly or
device according to this invention.
In the interior of a cone a there are arranged helical or screw-like sheet metal
vanes which in the arrangement illustrated are left handed but which may be
right handed if preferred. These vanca serve to catch and compress air when the
washing device is rotated in a downward and suitable direction and to convey
such air under considerable and constantly increasing pressure into the washing
liquor or articles being washed; and when the device is rotated in the reverse and
upward direction, air will be powerfully sucked in, from the washing liquor or
articles being washed. This has the effect of producing an intimate stirring or
intermingling of the washing liquor with air which are caused to pass through the
interstices or pores in the articles. being wasbed. This intermingling of the
washing liquor, or articles. being washed, with small bubbles or vesicles of air
quickly produces a thick soapy lather whereby the articles under treatment are
thoroughly washed and cleansed. This mode of operation serves to distinguish a
washing dolly according to this invention from the so-called air-dollies, heretofore
proposed inasmuch as the latter are always so constructed as to, execute only a
vertical up. and down, motion, whilst the pockets or double-cones provided in the
cones of the said air-dollies only exert a suction upon the air, and transfer this
air only to a very slight extent to the washing liquor or articles being washed.
The number of the spiral air-vanes in a dolly according to this invention may
vary according to the dimensions of the apparatus. The direction of the vanes
depends on the direction of movement it is desired to impart to the washing cone
whilst it is being screwed or rotated down into the articles being washed. Thus,

page_text: the apparatus illustrated must when in use, be rotated with a right hand motion, 80
that the several vanes b shall catch the air, and force it towards the centre with a
constantly increasing pressure, and then force it into the washing liquor through
the meshes and interstices of the articles being washed.
In the screwing motion out of the washing liquor or articles being washed the
air on the contrary is sucked in.
In the construction shown, the handle-rod or shank / terminates in a socket c that
partly of cylindrical and partly of truncated conical shape. This socket extends
partly through the cone a, which is strengthened at its upper end by the jacket d,
and is soldered to the upper part of the shell of the cone a, to the ring or
cylindrical portion e, and also to the air vanes b. In this manner there is provided
a firm attachment between the cone a, the air vanes b and the handle-socket c, so
that, when in use, the cone cannot become disconnected from the handle, and
great durability of the apparatus is ensured, which is a feature that has been a
seriously felt desideratum in the air-washing devices heretofore in use.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A washing dolly or device comprising a cone a provided internally
with air vanes b arranged spirally according to the intended direction of rotation
of the cone, the arrangement being such that when the cone is rotated with a
downward screwing motion air between the vanes will be gradually compressed and
forced into the washing liquor or into the articles to be washed so as to thereby
produce an energetic stirring or intermingling action, and on the cone being
rotated with an upward screwing motion in the reverse direction a suction with
consequent rarefication of the air will take place with the result that air and washing
liquor will be drawn through the interstices or pores of the articles being washed,
and an effect produced analogous to that produced by the downward movement
substantially as herein described.
2. A washing dolly or device of the kind specified in Claim 1, constructed with
a bandle-socket c that extends into the interior of the cone a, and is fixed to the
reinforced shell d of the cone a, to the ring e, and to the air vanes b, substantially
as herein described for the purpose specified.
3. The improved washing dolly or device shown in and described with reference
to the drawings.
