PROVISIONAL SPECIFICATION.
Improvements in Machinery for Washing Plates, Dishes, and similar
Articles.
I, GEORGE WILLIAM BENJAMIN CREES, of Wingfield near Trowbridge in the County
of Wiltshire, Gentleman, do hereby declare the nature of this invention to be as
follows
This invention has for its object the construction of a simple, effective, and.
economically built machine for washing plates, dishes, and similar articles, and
suitable either for domestic use, or for hotels, restaurants, steam ships, or any
establishments requiring to cleanse a large number of plates, dishes, and the like within
a short period of time.
In carrying out my invention, I provide a box, trough, or receptacle preferably
rectangular on plan and through or near the centre of which is mounted in suitable
bearings a block or roller grooved or otherwise prepared to carry brushes or other
cleansing agents fixed or fitted therein or thereon in the form of an Archimedian
screw.
This block carrying the brushes &c. is revolved my suitable mechanisin and I prefer
to use an arrangement of chain wheel gearing actuated by a fly wheel and handle,
treadle or other device.
At one side of the box or receptacle I mount one or more screw or worm rollers,
plain rollers, or endless bands also actuated by the chain gearing or other device for
transmitting motive power and arranged to run at such a speed as will ensure the
proper revolution of the plate or other article placed in the machine and which when
its edge rests against them or either of them is thereby caused to travel along the
roller or barrel.
On the machine being started a plate is placed between the brushes coiled round
the roller or barrel and usually near to the handle or other device, the lower edge
resting against or on the grooved roller or barrel and the upper edge against one of
the side rollers before described. On the rollers with the brushes being revolved the
plate is caused also to revolve in the opposite direction to the brushes carried by the
roller or barrel and travels through them towards the opposite end of the said roller
or barrel when it drops upon a flap pad shoot or band of suitable material, formed in
such a manner as to deliver the said plate or article clear of the box or receptacle and
if desired also into a tank or the like.
I may fit a tap or taps to the box or receptacle in a convenient position for carrying.
off the water therefrom.

COMPLETE SPECIFICATION.
Improvements in Machinery for Washing Plates, Dishes, and similar
Articles.
I GEORGE WILLIAM BENJAMIN CREES of Wingfield near Trowbridge in the County
of Wiltshire Gentleman 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 has for its object the construction of a simple effective and
economically built machine for washing plates dishes and similar articles and suitable

page_text: either for domestic use or for hotels restaurants steain ships or any establishment
requiring to cleanse a large number of plates dishes and the like within a short period
of time.
In carrying out my invention 1 provide a box trough crate or other receptacle
preferably rectangular on plan in which is mounted in suitable bearings a block or
roller round which I spirally attach sections of wood or other suitable material
carrying brushes or other cleansing agents fixed or fitted therein or thereon in the
form of a screw and between these convolutions I cut or form a groove or notch in
the block or barrel or if desired the groove or notch may be dispensed with.
The block carrying the brushes or other cleansing agents is revolved by suitable
mechanism and I prefer to use an arrangement of chain wheel gearing actuated by a
flywheel handle treadle or other device.
At one side of the box framework or receptacle I mount one or more screw or worm
rollers plain rollers or endless bands also actuated by the chain gearing or other device
for transmitting motive power and arranged to run at such a speed as will ensure the
proper revolution of the plate or other article placed in the machine.
Referring to the accompanying sheet of drawings and to the figures and letters of
reference marked thereon,
Figure 1 is a sectional elevation showing the apparatus fitted in a box or tank
capable of holding water or other fluid and actuated by gearing worked as shown in
this drawing by a handle.
Figure 2 is an end elevation of the box or tank showing a suitable gearing for
actuating the machine.
Figure 3 is a detailed drawing of one section of the brush back showing a method
of attaching the same to the block or barrel.
Figure 4 is an enlarged sketch of the delivery end of the block shaft or barrel
showing a plate being ejected from the machine.
In the drawings a box or tank is shown capable of holding fluids but the apparatus
may be fitted to an open chamber framework or crate of any suitable material so that
it may be placed in a larger receptacle containing fluid and removed therefrom at
will if found desirable the fluid being free to circulate between and around the
brushes.
In the machine here represented A is a box tank or receptacle having mounted
therein on bearings B B a central stock shaft or barrel C in which is cut a spiral
groove D.
Upon and round the barrel C I. attach sections such as E (Figure 3) on which at
one or both sides are fitted coir bristles or other cleansing agents. These sections are
jointed and fitted to each other and to the block or barrel in such a manner as to
form a worm or screw and the brushes cuir etc. are sufficiently long to embrace and
thoroughly cleanse any article lying between them.
In Figure 31 show a convenient form of a section of brush back (without the coir
or bristles) as above described and a metal band H is attached to the underside and
shaped at either end to engage with the last and following section until the worm or
spiral is completed the end sections being screwed or otherwise secured to the barrel
or block; the ends of the sections are also mortised to fit studs upon the barrel.
At convenient points in the back of the receptacle I mount other plain or worm
rollers J K revolving in bearings J¹ J2 K' K² and actuated by sprocket wheels L M
and the chain gearing shown in Figure 2.
On the flywheel N (Figure 2) being turned the endless chain O passing over the
teeth of wheel P sets in motion the barrel or stock C and at the same time the
rollers J K are revolved. A plate or dish being placed at any point between
the brushes and with its edge in the spiral groove D the upper portion of the edge
rests against roller J or K according to its size and the apparatus being in motion is
propelled along the spiral groove D and between the brushes until it arrives at or
near Q (Figure 1) when the groove running out it rises to the face of the block or
barrel and on to a block or cam Y which is fixed thereon for the
purpose of raising
the plate or other article clear of the brushes and it then assumes the position shown

page_text: by dotted lines in Figure 4 and falls upon the tilting board or platform R which is
controlled by a cord chain or spring passing over a pulley T and regulated by a
balance weight U or any other device may be employed. The platform R is made
to assume the position shown in Figure 4 by means of a cam W attached to the end
of the block or barrel C. The plate or article falling upon the tilting platform is
projected into a tank or other receptacle containing preferably hot or cold fluid for
rinsing purposes and it is now effectually cleansed and may be taken out by hand
and stacked for drying or the plates may be carried by a continuation of the spiral
block (without brushes) through hot fluid and packed in an elongated trough or
receptacle or I may add the racking arrangements described in the Specification of
Letters Patent granted to me numbered 9469 and dated 4th July 1887.
The box tank or receptacle may be provided with outlets overflows or arrangement
for a continuous flow of fluids and may be mounted on legs or supports V or fixed
in any desirable manner so as to be worked either by hand or power.
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 machines for cleansing plates dishes and like articles the use of brushes or their
equivalents fitted or fixed spirally or in the form of a screw round revolving stocks
barrels or shafts such as C as and for the purposes hereinbefore described and sub-
stantially as illustrated by the accompanying sheet of drawings.
2. In machines for cleansing plates dishes and like articles the use of revolving
stocks shafts or barrels having spiral or worm grooves such as D cut or formed therein
or thereon.
3. In machines for cleansing plates dishes and like articles the mounting of
brushes or their equivalents spirally or worm fashion round revolving stocks shafts or
barrels having cut or formed therein or thereon spiral or worm grooves.
4. In machines for cleansing plates dishes and like articles the combination of
spirally formed brushes revolving stocks shafts or barrels having therein or thereon
spiral or worm shaped grooves D and plain or spirally grooved rollers J K sub-
stantially as and for the purposes hereinbefore described.
5. The construction and arrangement of a machine or apparatus for washing or
cleansing plates dishes and similar articles substantially as herein described and as
illustrated by the accompanying sheet of drawings.
