Plate and Dish Washing Machine.
We GEORGE WILLIAM BENJAMIN CREES of 8 High Street Warminster in
the County of Wilts, Managing Director of Crees and Co., Limited, and CREES
AND COMPANY, LIMITED, of 8 High Street Warminster in the County of Wilts,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide a machine for cleansing plates dishes
and the like of such a size and construction as shall render it convenient for use
in small hotels or private houses where a machine such as described in the
Specification of Letters Patent No. 2015 dated 7th February 1890 would be too
large and expensive.
In carrying out my invention I provide a rectangular box or case preferably of
wood and which may stand on legs and capable of containing hot water or other
cleansing agent and in this case I mount a pair of circular brushes by mounting
two discs on the faces of which are secured bristles coir brass or like material
upon a central axis in which is a tapered groove (or a grooved block) facing the
point at which the bristles of each brush meet. The axis carrying the brushes is
carried in bearings fixed conveniently in the sides of the outer case and projects
through one side in order to carry the gearing and handle by means of which the
double brush is rotated.
To one end of the case or box and at or near the top we secure the ends of two
chains or their equivalents which pass round and under the brushes and are led
up to and over a pulley wheel mounted in a convenient position over the opposite
end of the case or box these chains terminating in a balance weight or weights.
At intervals on the chains we secure at right angles to their length cross pieces
rollers or laths connecting the two chains and forming a broad open band kept
normally against the bottom of the brushes by the action of the balance weight.
A plate is placed between the brushes with one part of the edge resting in the
groove in the central axis and the opposite edge resting against the self
adjusting band which keeps it thus within the brushes and close up to the central
axis or block thereon.
The brushes are rotated by suitable gearing and handle and the plate or article
passes round and through the water in the lower part of the case until thrown
out automatically by coming in contact with a cross piece within the brush fitted
to the end of a metal rod or lifter which raises the plate and deposits it upon a
delivery board which in turn is tilted by a cranked lever pivotted to the end of
the case and actuated by a point or pin on arms which are carried across the
diameter of the discs bearing the brushes and fixed to a gear wheel revolving at a
different speed and to which are attached devices for retarding the passage of the
plate or article through the brushes.
Guides may be fixed below the brushes if required to regulate the course of
the chain band.

We GEORGE WILLIAM BENJAMIN CREES of 8 High Street Warminster in
the County of Wiltshire Managing Director of Crees and Company Limited and
CREES AND COMPANY LIMITED of 8 High Street Warminster aforesaid
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 :-
The object of our invention is to provide a machine for cleansing plates dishes
and the like of such a size and construction as shall render it convenient for use in
small hotels private houses or establishments where a machine such as described in
the Specification of Letters Patent No. 2015 dated 7th February 1890 would be
too large and expensive.
In describing our invention we shall refer to two sheets of drawings accom-
panying this Specification and to various reference letters thereon and
Figure 1. is a sectional elevation of front of the machine part of case being cut
away.
Figure 2. is a view of part of the machine shewing lifting and tilting apparatus.
Figure 3 is an end perspective view (part of case being cut away) shewing
brushes and action of machine, and
Figure 4. is a transverse section through brushes.
In carrying out our invention we provide a rectangular box or
Case A.
preferably of wood, which may stand on legs or otherwise and be capable of
containing hot water or other cleansing agent and in this case A we mount
oppositely a pair of circular brushes B. B. consisting of two discs on the inner
faces of which are secured bristles, coir, bass or like scrubbing materials and upon
a central wood block or hub C in or round which is a tapered or V shaped
groove D facing or in plane with the meeting point of the bristles of the
.brushes B. B.
A metallic axis E passes through the block or hub C to which it is fixed and is
mounted in bearings F. F. one of which may be conveniently on one side of the
outer case or box A and the other in or on the interior partition G. This central
axis E. projects through the side of case A. in order to carry the gear wheel H.
engaging with wheel J on spindle K. rotated by handle and flywheel L.
To one end of the case or box A and at or near the top say at M. we secure the
ends of two leather bands or chains or their equivalents N. N. which pass partly
round and under the brushes B. B. and are led up to and over a loose pulley O.
placed in a convenient position over the opposite end of the case or box A.
These bands or chains terminate in balance weights P' P' which may form part
of the band or chain as hereafter described.
At intervals in the bands or chains and between them we secure at right angles
to their length cross pieces rollers or laths P. P. connecting the two bands or
chains N. N. the whole forming a broad open baud or belt kept normally near to
the bottom of the brushes B. B by the action of the balance weights P P¹ which
may be of lead and arranged in the same manner as the cross pieces or laths P. P.
Guides or stops p. p. are provided serving to keep the band or belt in position and
preventing it from unduly pressing against the revolving brushes.
.
A plate or the like R. is placed between the brushes B. B. with one part of the
edge resting upon or against the self-adjusting band or belt N. N. which tends to
keep it within the brushes B. B and if a large one close up to the groove in
hub C. The brushes B. B are rotated by gearing and handle L before described
and the plate or article R. passes round the hub C through the brushes B. B and
water in the lower part of the case A until thrown out automatically upon

page_text: platform S by coming in contact with an arm or crosspiece T. within the brush
fited to the end of a metal rod U as hereafter described which raises the plate
and deposits it upon the delivery board or platform S. The travel or speed of the
plate is retarded so that the brushes make several revolutions (thereby thoroughly
scrubbing the plate) whilst the plate makes only part of a revolution round the
hub although it revolves freely on its own axis, and this is effected as follows:
We mount on loose bearings on the central axis E of the brushes an arm or bar V
free to revolve on said axis and secured by pins or bolts to a _cogwheel W. also
losely mounted on axis E and gearing into small gearwheel X rigidly fixed on
spindle K and thus revolving at a less speed than the brushes B. B.
At each end of this arm V we attach crosspieces Y. Y. from which depend or
project rods Z. Z. passing between the. brushes and having at their extremities
short arms at right angles thereto Z1 Z' against which the smaller plates come in
contact and are thereby retarded in their transit.
To each of the crosspieces Y. Y. and clear of the brushes we fit a (preferably)
wooden block a having a notch b on one edge facing the plate R (see Figure 2)
and against or in this notch the edges of the larger plates rest during their
transit.
Over the delivery board or platform S we form a hood or cover c which prevents
splashing of water and also to some extent acts as a guide to the plates on their
emerging from the machine and to this hood or to a convenient part of the
machine we secure a metal rod U projecting forwardly and downwardly between
the brushes and carrying at its extremity a cross piece T. When a large plate in
its travel comes in contact with the crosspiece T it rides up and through the
notch 6 falling outwardly upon the delivery board S.
The rods Z. Z. are pivotted in bearings d. d below the crosspieces Y. Y. and on
coming in contact with the extremities T of the fixed rod U are tilted backwardly
and upwardly so throwing up and ejecting any small plates resting against them
and which by reason of their size could not have any portion of their edges
resting against the notch bin block a.
After a plate has been lifted automatically and deposited upon the platform S
the said platform, which is pivotted at e Figure 1., is tilted up by the action of a
two-armed lever and the plate slides off into the water contained in that portion
of the outer case A. marked g which is prepared to receive it or into any other
receptacle so arranged for receiving the cleansed plates. The lever f is actuated
by pins h. h on the side arm or bar V., or other means for tilting the platform
may be used.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that what
we claim is.
1. In machines for cleansing plates, dishes and like articles the combination of
oppositely placed circular revolving brushes such as B. B. mounted on a central
hub or block having a groove or chase around it with a self adjusting guide
band or belt such as N. N., lifting devices such as T. U. V. Y. Z. to raise plate or
the like from the brushes and tilting or ejecting apparatus such as S. e. f. g. the
whole substantially as herein before described with reference to the accompanying
drawings.
2. The general arrangement and construction of machine for cleansing plates
dishes and the like substantially as herein before described and as illustrated by
the accompanying drawings.
