Year: 1887

page_text: I, GEORGE WILLIAM BENJAMIN CREES, of Pomroy Manor, Wingfield, 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 relates to the construction of an improved machine or apparatus for
washing plates dishes and similar articles.
In the accompanying drawings,
Sheet I. Figure 1 represents a side elevation of my apparatus.
Sheet II. Figure 2 represents an elevation of the same on the reverse side of the
apparatus.
Sheet III. Figure 3 represents a longitudinal section of the machine.
Sheet IV represents a plan of the machine.
Figure 5 a plan of the box or trough showing the small brushes only in position.
On Sheet V. Figure 6 is a vertical transverse section of the machine taken through
the main brushes on line a. b. of Figure 4.
Figures 6. 7. 8. 9. 10. 11. 12 are details of the castings or frames for carrying the
gearing of the machine.
On Sheet VI Figures 13 and 14 are end views of the machine.
On Sheet VIII show a vertical transverse section of a modification of the machine.
A is a trough or box to contain water (hot or cold) to which may be added soap
soda or other suitable detergent, and through which the plates dishes or similar articles
are fed by the action of the machine.
In the trough or box 1 arrange one or more circular brushes B, B', B2, which may
have bristles disposed on the circumference, one or both sides, or all combined.
These brushes may be arranged to be driven in the same or different directions,

page_text: Figure 6 explains fully the method of driving the various parts of the apparatus
from the pulley or fly wheel shaft.
I arrange castings or frames C, C, to carry the various centrally placed bearings.
D is the pulley or fly wheel shaft mounted in the casting or frame wheel C. It carries
pinion E driving a spur wheel E' mounted on the sleeve of the brush B².
a
Another
spur wheel E2 drives a spur wheel E³ spindle D on which the central brush B'
is keyed.
The spindle D' carries a spur wheel E, driving a pinion E on a countershaft 1)² in
the casting or frame C. The shaft D2 carries a pinion E driving a spur wheel E7 on
the sleeve of the brush B.
A pinion E on the shaft D drives a spur wheel E' attached to a sleeve running on
the spindle D' said sleeve carrying a set of arms or conveyors G running between
brushes B B².
On shaft. D is a pinion E gearing into a spur wheel E" attached to a sleeve running
on the spindle D' said sleeve carrying also a set of arms or conveyors G¹ running
between the brushes B and B².
The shaft D carries a chain or transmitting wheel H, and the pinion Es drives a
spur wheel Emounted on a countershaft D³ and which carries a pair of chain
wheels H1, H2, the use of which gearing will be more particularly hereafter referred to.
Motion communicated from shaft D will drive the brushes B, B1, B2, and the
conveyors G. G will also be driven but at a different speed to that of the brushes so
that the conveyors can feed the plates dishes or similar articles between the brushes as
more particularly herein after described. 1 arrange also subsidiary and smaller
brushes I, I, I, see Figures Ill and V and I drive these off their shaft I³, which
works in the stuffing box I by chain wheel I' driven off chain wheel H on counter-
shaft D³. I is an idle pinion to guide the chain and set it up if required. J, J', J, J³, are
guides of wood or other suitable material to guide the plates dishes or similar articles
through their passage through the machine by the action of the conveyors G. G³.
To feed the plates dishes or similar articles to the brushes I employ means as
follows:-
I arrange a worm K running with a shaft K' at one end of the box or case A and
driven by bevel gearing or other gearing off the chain wheel H¹ on the counter-
shaft D3, which runs over the chain wheel K2 carrying pinion K³, driving the spur
wheel K on the shaft K³ which in turn drives the worm shaft K¹.
K, K7, are eccentrics on the shaft K³ the straps K, K³, of these eccentrics work
the push bars L, L', giving them a lifting and pushing action to feed the plates dishes
or similar articles to the conveyors G, G, by which they are taken between the brushes.
The worm K receives the plates dishes or similar articles from the push bars and feeds
them between the main brushes and the guides.
In Figure a plate is shown on the worm going to the brushes.
If desired canis or other devices could take the place of the eccentrics K' K'.
As the plates dishes or similar articles emerge at the other side of the brushes they
are lifted by the conveyors G. G¹ through a trap door M and from there slide on guides
or runners N N N N to within reach of a second set of conveyors O, O', on shaft O²,
driven by chain off the pinion H2 on countershaft D³.
The plates dishes or similar articles are then taken up to the receiving box P where
the weighted flap Q moved in a reciprocating manner by means of the slide Qand
link Qoff the driving shaft 02 driving the conveyors 00' (or otherwise driven by
suitable means) piles the plates dishes or similar articles against the stop R which is
attached to sliding rods R. R¹ so that the stop It slides outward in proportion as the
pile of plates increases but this action is controlled by suitable springs or balance
weights not shown in the drawings but the application of which can be readily
understood.
The box P containing the guides or runners N N¹ N2, N3, on which the plates dishes
or similar articles slide, is filled with hot or cold water agitated by a fan S, having
blades placed between the runners and driven by chain as shown off the shaft O
carrying the conveyors 0, 0)¹.

page_text: This rinses the plates dishes or similar articles to prevent grease or slimy matter
adhering to them as they leave the machine.
I do not confine myself to the use of a single rinsing box as P but may provide
more than one through which additional box or boxes the plates dishes or similar
articles are taken by extra conveyors.
In constructing machines of less capacity than before described and referring to
Sheet VII in which Figure 15 is a vertical elevation of my machine. Figure 16 a
vertical section thereof. Figures 17 and 18 transverse sections of the same.
I form a box or trough a similar to the other and have one or more revolving
brushes bcd through which the plates dishes or similar articles pass. e. f. are the
segmental plate guides similar to those in the larger machine, e, being eccentric to the
brushes so as to permit the entrance of the articles. The conveyors shown in the
larger machine are dispensed with.
To prevent a too speedy passage of the plates dishes or similar articles I employ
two arms fixed on a bar h passing transversely through the machine and which are
put into a rocking motion by means of levers i. j. and rods k. k', on the outside of the
machine and which are actuated by a cam 1 an eccentric or other equivalent device in
accordance with the speed at which the brushes are made to revolve and at which it is
desired to allow the plates, dishes or similar articles to travel through the machine.
The conveyor employed to lift the plates or similar articles out of the machine
consists of a bar m armed with two arms n and placed so on the face of the brush body
that in the revolving motion of the brush a slight turning action on its own axis is
imparted to the bar m and through to the two arms n. A short lever o at the end
of the bar controls the turning of the bar by being lifted or depressed by the pointer p
which is mounted on a pin fixed on the underside of the trough or box and which
again is moved or actuated by the lever i outside. The outside lever i is raised or
lowered by the action of the same cam, eccentric or equivalent device l. which also
controls the movement of the arms h and the bar g upon which they are mounted.
The train of gearing adopted to drive the various parts of the apparatus is indicated
by the Figures 1 to 8. The crank shaft and pinion 1 drive pinion 2 driving the large
spur wheel and cam shaft 3 which drives the large brush shaft 4 which turns the idle
pinions 5. 6 which in turn drive the small brush shafts 7 and 8.
The rod as it rises and falls also rocks a shafts which by means of a levert moves
an oscillating slide u by which the feeding in of the plates dishes or similar articles is
accomplished. is a trap door which permits the articles to leave the machine.
The feeding devices shown in the larger machine may be employed or equivalent
devices substituted.
The machine will deliver the plates dishes or similar articles automatically and
I prefer to let them slide simply into a suitable vessel containing water heated or
otherwise prepared by soda or suitable detergent so that grease or slime may be
removed and the plates so rinsed.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
First. In a machine for washing plates dishes or similar articles the combination of
large rotating brushes such as B, B1, B2, with segmental guides such as J, J, J, J³,
against which they work and smaller brushes such as I, 11, 12, and also with or without
rotating conveyors placed between the larger rotating brushes and driven at a different
speed thereto for the purpose of carrying the plates forward between the rotating
brushes substantially as described.
Secondly. In a machine for washing plates dishes or similar articles, the employment
of rotating conveyors in combination with curved guides or runners, for the purpose
of taking the said articles through the brushing or washing or rinsing chambers
substantially as described.
Thirdly. In a machine for washing plates dishes and similar articles, the employ-
ment of a feeding screw such as K and lifting or pushing bars such as L L for the
purpose of feeding such articles to the machine substantially as described.

page_text: Fourthly. In apparatus for washing plates dishes and similar articles in which
rotating brushes working against curved or segmental guides are used, the employ-
ment of a reciprocating stop or stops arranged to check the too rapid motion of the
articles through the apparatus substantially as described with reference to Figure 15
of the accompanying drawings.
Fifthly. Apparatus for washing plates dishes and similar articles arranged combined
and operating substantially as described and illustrated in the accompanying drawings.
