Improvements in Apparatus for Washing Dishes and other Articles
and Substances.
Communication from BERT WILLIAM CRISSEY, of Sydney, in the Colony of
New South Wales, Commercial Agent.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Patent Agent, do hereby declare the nature of this inven-
tion 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 an improved contrivance for washing dishes and other
articles and substances and although specially suitable for dish-washing it may be
advantageously used for washing tableware fruit vegetables and such like. By it
the dish washing may be carried out in a comparatively very short space of time
without handling the dishes &c. during the process or in any way subjecting the
hands of the attendant to the influence of the hot or scalding water and soap
soda &c. used.
This improved contrivance for washing dishes and other articles and substances
consists of five main parts an outer dish or bowl a turbine or centrifugal water lifter
a bottomless inner bowl and spray or shower director a perforated false bottom a
central spindle with operating handle and a partial cover and spindle bearing.
The turbine is pivotted in the space between the outer bowl and the inner one
under the false bottom and is revolved by a toothed wheel loose upon the central
spindle in gear with intermediate toothed wheels one of which is in gear with a
toothed wheel fast on said vertical spindle so that the speed of the turbine is
considerably in excess of that of said spindle. The inner bowl which is perforated
at its uppermost part fits down over the central spindle and is tightly fastened to
the outer bowl by clips or clamps which are self locking. The perforated false
bottom takes over the orifice and upon the concave of the inner bowl and prevents
The top
the passing to the turbine of large lumps of debris from the dishes &c.
partial cover also fits over the central spindle and a bar across its centre forms the
upper bearing.of said spindle which finds a lower bearing on the inner centre of
the outer bowl and forms a bearing for the turbine.
But in order that this invention may be clearly understood reference will now be
made to the drawings herewith in which
Figure 1 is a sectional elevation of an improved contrivance for washing
dishes &c. constructed according to this invention.
Figures 2 to 9 show in section and plan the different parts as hereinafter
described while
Figures 10 and 11 show front and side views respectively of a peculiarly
constructed handle and clamp.
Figure 12 shows enlarged detail of the gearing in the bowl.
The spindle B with toothed wheel B' at bottom is stepped upon a pivot pin A¹
on plate A in the centre of the bottom outer dish or bowl A said wheel B₁ gearing
with a pinion A fixed to wheel A' on pin A also rising from plate A³. The
wheel A gears with a pinion C₁ fixed to the boss of the turbine or fan or
centrifugal water lifter c running loose upon spindle B. The outside periphery of
said turbine is formed into blades C which when revolved throw the water
contained in the dish or bowl A up annular space A formed between said bowl and
the inner bowl D with perforations D' the neck D of which fits into the mouth of
the outer bowl and is clamped or fastened down by clamps a¹ the rubber packings D³
making a water tight joint with rim A'. The perforated plate E is passed over the
spindle B and rests upon the annular rim D₁ thus forming a false bottom to

page_text: the bowl D. One partial cover F is made to fit tightly into the neck D2 of the
inner bowl while the socket on bar F2 forms a bearing for the spindle B to
which a handle B2 is attached The clamp is hinged upon pins a eccentric
to the hinge 3 of handle a so that when the handle a is moved outwards from the
bowl A the clamp a' is raised and thus the pressure forming the joint between
the rim of the inner bowl D and that of the outer bowl A is released and the clamp
may be drawn over the rim of the inner bowl. When the inner bowl is replaced
the clamps a' are placed over the rim and each handle a is drawn downward and
inward towards bowl A the clamp moving eccentrically on hinge a³ which thus
tightens the clamp and forms the joint.
In operation after the dishes &c. have been placed within the inner bowl D upon
false bottom E hot water is poured therein percolating through the perforation in
plate E into the bottom of bowl A. Spindle B being now revolved the wheel B'
by means of pinion and wheel A³ A revolves pinion C and the turbine C the
blades C3 of which throw the water up space A and forces it through perforations D'
in jets upon the dishes &c. within the inner bowl which dishes &c. are cleansed the
water being over and over again drawn by turbine to the bottom of the outer bowl
and forced by blades C3 through the perforations. When required the water is
drawn off through orifice A8 in the bottom of the outer bowl A. All solid matter
too large to pass through the perforations are retained on plate E which after the
handle 12 is removed and the partial cover lifted off may be lifted out and
cleansed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
:-
First. An improved dishwasher or contrivance for washing dishes and other
articles and substances having its various parts constructed combined and arranged
in the manner and for the purposes substantially as herein described and explained
and as illustrated in the drawings.
Second. In a dishwasher or contrivance of the class set forth the combination
and arrangement with an outer bowl and an inner bottomless and perforated bowl
of a turbine fan or water lifter and means for revolving same adapted to force water
upwards between said bowls and inwards through the perforations in said inner
bowl substantially as herein described and explained.
Third. In a dishwasher or contrivance of the class set forth the combination and
arrangement with an outer bowl such as A and an inner bottomless and perforated
bowl such as D of the clips or clamps a a¹ a² a³ substantially as herein described
and explained and as illustrated in the drawing.
Fourth. In a dishwasher or contrivance of the class set forth the combination
and arrangement with an outer bowl such as A an inner bottomless and perforated
bowl such as D a partial cover such as F a turbine or fan such as C of a central
spindle such as B and gearing such as B₁ A³ A and C substantially as herein
described and explained and as illustrated in the drawing.
