PROVISIONAL SPECIFICATION.
An Improved Dolly for Washing Purposes.
I JAMES WILSON of 50 Morant Street Poplar in the County of Middlesex
Engineer do hereby declare the nature of this invention to be as follows:-
-
The object of my invention is to provide a dolly for wasbing purposes that shall
be simple in construction easy in action and efficient in operation.
To carry out this object I make preferably of sheet metal and especially zinc a
cylinder of the desired length and diameter and to the one end of this cylinder is
connected the smaller part of the frustrum of a cone or other bell shaped or
trumpet shaped or other enlarged mouth the outer end whereof is open and may be
of any desired diameter while on and across the other end of the cylinder is
stretched a piece of suitable material preferably perhaps of leather firmly secured
in position in which diaphragm are made the desired number of small holes. At
the point of connection of the cylinder and the conical or other enlarged mouth
are secured two frustra of cones one of which extends the desired distance along
the cylinder and terminates as a small opening placed centrally in such cylinder or
thereabouts while the other frustrum extends the desired distance along the conical
or other enlarged mouth and terminates as an enlarged opening placed centrally in
such conical or other enlarged mouth or thereabouts. There is thus created an
annular space around each of these frustra which gradually decreases until it is
entirely closed at the point of connection aforesaid. A flange or the like or other
handle may be fitted round or near or on or to that end of the cylinder whereon is
the diaphragm for convenience of holding.
This dolly is held vertically or thereabouts with its enlarged mouth a little
below the surface of the water and is gently or otherwise worked or moved up
and down.
Either or both of the internal frustra of cones may when desired be dispensed
with although in these cases the dolly will not so rapidly or so thoroughly perform
its function.
Although the transverse areas of all parts of this dolly are most conveniently
and preferably of a circular shape yet they may also be made of any other shapes
as may be desired.

An Improved Dolly for Washing Purposes.
I JAMES WILSON of 50 Morant Street Poplar in the County of Middlesex
Engineer 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:-
1
The object of this my invention is to provide a dolly for washing purposes that

page_text: shall be very simple and cheap in construction extremely easy and light in action
and highly efficient and beneficial in operation.
In order the more clearly to explain this my invention and in what manner the
same is to be performed I refer to the accompanying drawing wherein
Figure 1 is a longitudinal section of this my dolly
Figure 2 is a view of the dolly from and of the top thereof Figure 3 is a view of
the same from and of, the bottom thereof and
Figure 4 is an elevation of the dolly.
A tube A is made of any suitable material perhaps preferably of sheet metal
and especially zinc and of any desired length and size and in transverse area most
Conveniently of a circular shape. To and on one end of this tube A is attached or
connected or therewith is formed or created the corresponding smaller end of a
frustrum of a cone B or any bell-shaped or trumpet-shaped or other enlargement
preferably made of the same material as such tube A the outer end or mouth B¹ of
which enlargement B is open and this enlargement B likewise may be made of any
desired length and size and in transverse area most conveniently of a circular
shape. The other end of the tube A is closed it may be by stretching on and
across the same a piece of any suitable material such for example as leather or as
is perhaps most convenient by fitting thereon and thereover a cap C preferably also
made of the same material as such tube A which diaphragm or cap C is in every case
firmly and tightly secured in position and in and through the same is or are made
one or more very small holes D one such hole D being as a general rule and in the
majority of cases amply sufficient.
Inside this appliance
so made as is hereinbefore described are placed two frustra
of cones E and F or other similarly tapered devices preferably also made of the
same material as the tube A. which frustra E and F or other devices may be
attached or convected to each other by and through their corresponding ends or
may be formed or created together and also are rigidly and tightly attached or
connected to the place of attachment or connection or of formation or creation
herein before described of the tube A. and or with the enlargement B as is shewn
at the point G in Figure 1. The one frustrum E or other device extends the
desired distance along the enlargement B being it may very conveniently be about
half the length thereof and it terminates as and in a large open mouth E' placed
or situated centrally in such enlargement B or thereabouts and this frustrum E or
other device in transverse area is most conveniently of a circular shape. The
other frustrum F or other device extends the desired distance along the tube A
being also it may very conveniently be about balf the length thereof and it terminates
as and in a small open mouth F¹ placed or situated centrally in such tube A or there-
abouts and this frustrum F or other device in transverse area likewise is most
conveniently of a circular shape. Thus and in this manner there is created around
each of these frustra E and F or other tapered devices and between the same and
the tube A or the enlargement B an annular or other suchlike and similar air.
space which may be and preferably is somewhat narrow at its commencement and
then gradually or otherwise decreases until it is entirely and completely closed at
the common place of attachment or connection at the point G hereinbefore
described.
This my dolly so made and fitted as is bereinbefore described in a vertical
position or thereabouts is gently and as is most efficient and beneficial somewhat
rapidly worked or moved up and down in a vertical or perpendicular direction or
thereabouts above the articles that are to be washed and the length of this recipro-
cating movement is or ought preferably to be such and so long that at the top of
its stroke or in its uppermost position the mouth B₁ of the dolly is still below the
surface of the water while at the bottom of its stroke or in its lowermost position
the mouth B' of the dolly just lightly touches the articles in the water by which
arrangement and method of working these articles will very rapidly efficiently and
beneficially be cleaned as is desired.
This motion hereinbefore described can when desired be given to the dolly by

page_text: and through any ordinary and suitable machine or apparatus or otherwise driven
by any convenient and appropriate power but the smaller dollies are perhaps
preferably worked by hand. In this case it is very convenient to fit on and round
and preferably near the top of the tube A a flange or other like device for
convenience of holding or it is perhaps still more convenient to fit thereon a loop.
or handle H as is shewn in Figure 4 wherethrough the thumb can be passed when
the fingers surround and clasp this tube A by which arrangement this dolly can and
will be firmly held without any inconvenient and undue exertion of force although
the outside of such dolly and the hand that holds the same may and generally if
not invariably will be wet.
Although as is indeed very evident all parts of this dolly may be made of any
absolute and relative sizes as may be deemed to be expedient or desirable or
necessary in each particular case yet I would state that the relative sizes thereof
that are herein before mentioned as also those that are shewn in the accompanying
drawing are extremely suitable and highly efficient while the absolute sizes thereof
could be arranged and settled as might be appropriate having regard to the size or
the quantity or the number of the articles that are to be treated by the particular
dolly at one and the same time and it may be the material or materials of which
these articles are made and also to the apparatus in which such articles are to be
placed for treatment and further to the power or person that is to work the dolly
as also when required to any other surrounding circumstances.
Again although the transverse areas of all parts of this dolly are most
conveniently and preferably made of a circular shape as is herein before stated and
as is shewn in the accompanying drawing yet I would also state that as is indeed
very obvious these transverse areas and all or any of them may be made of any
other shape or shapes that may in each particular case be deemed to be expedient.
or desirable or necessary.
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:
1. In a dolly for washing purposes a tube A the one end whereof is closed but
has one or more very small holes D and on the other end whereof is an.
enlargement B with an open mouth B' in combination with two internal frustra of
cones or the like E and F tightly attached together and to the tube A and the
enlargement B at the point G which frustra or the like E and F have open
mouths E and F' substantially as hereinbefore described and set forth.
2. The improved dolly for washing purposes substantially as hereinbefore:
described and shewn in the accompanying drawings.
