Improvements in and relating to Apparatus for Cleaning the Sieves
of Sifting, Grading, and analogous Machines.
CHARLES HESSEY STUBLEY, Miller, 3, Rock Terrace, Mansfield, Nottinghamshire,
do hereby declare the nature of this invention to be as follows:-
.
For this purpose I fasten a number of brushes or scrapers to a suitable rod or
rods which is placed inside the sieve boxes and underneath the sifting surface.
The rod or rods are allowed to slide in suitable groves provided for them.
The groves are supported by four or more screws, the screws pass through the
bottom of the boxes which contain the sieves and are connected to the groves
which support the sliding rod or rods.
By working the screws up or down the brushes are made to come in contact
with the sifting surface more or less as required.
To give the desired movement to the sliding rod or rods and projecting through
the ends or sides of the sieve boxes is a connecting rod, these connecting rod ends
are provided with a cylinder which revolves as the rods are slidden alternately
first in one direction and the other.
Motion is given to the connecting rods and rods which carry the brushes or
scrapers by means of levers, movement is given to the levers preferably by a worm
and wheel.
Attached to the wheel is a suitable pin, as the wheel revolves the pin works
in a slit at one end of the lever at the other end of the lever is an arrangement
of a socket or sockets which receive the cylinders which are at the end of the
connecting rod or rods.
The sockets are allowed to move loosely on spindles so that as the sieve boxes
rotate or reciprocate the sockets accomodate the motion of the sieve boxes and lever.
By having the pin moveable in the wheel the lever is made to slide the rod or
rods any desired distance.
Other means may be employed to work the lever. This arrangement of brushes
may be applied to purifier sieves.

page_text: to be performed, to be particularly described and ascertained in and by the follow-
ing statement: -
The object of this invention is to clean the sieves of sifting grading and
analogous machines by brushes or scrapers and so arranged that they may work
inside and with the sieve box or boxes, and underneath the sifting surface or to
work underneath the sifting surface without being carried by the sieve box or
boxes and to move the brushes or scrapers alternately any desired distance either
lengthwise or across the sieve or sieves.
For this purpose I fasten a number of brushes or scrapers to a suitable rod or
rods which is placed inside the sieve boxes and underneath the sifting surface.
The rod or rods are allowed to slide in suitable grooves provided for them, the
grooves are supported by four or more screws, the screws pass through the bottom
of the boxes which contain the sieves and are connected to the grooves which
support the sliding rod or rods.
By working the screws up or down the brushes are made to come in contact
with the sifting surface more or less as required.
To give the desired movement to the sliding rod or rods and projecting
through the ends or sides of the sieve boxes is a connecting rod, these connecting
rod ends are provided with a cylinder which revolves as the rods are slidden
alternately first in one direction and then the other. Motion is given to the con-
necting rods and rods which carry the brushes or scrapers by means of levers.
Movement is given to the levers preferably by a worm and wheel.
Attached to the wheel is a suitable pin, as the wheel revolves the pin works
in a slit at one end of the lever, at the other end of the lever is an arrangement
of a socket or sockets which receive the cylinders which are at the end of the
connecting rods or rods.
The sockets are allowed to move loosely on spindles so that as the sieve boxes
rotate or reciprocate the sockets accomodate the motion of the sieve boxes and
lever.
By having the pin movable in the wheel the lever is made to slide the rod or
rods any desired distance. Other means may be employed to work the lever.
This arrangement of brushes may be applied to purifier sieves.
In order that my invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
Figure 1 is a plan of sifting apparatus with my sieve cleaning arrangement
attached according to my invention.
Figure 2 is a vertical transverse section of the same.
Figure 3 is an end view shewing a brush, rod and grooves.
The figures of the apparatus which they represent may be of any dimensions
in length breadth or depth.
A is a suitable rod which carrys the brushes. A1 is the brushes. P is the
grooves which the rod A is allowed to slide in. B1 B1 are the screws which
raise and lower the grooves P passing through the holes in the plates B. C is
the connecting rod which is firmly fastened to the rod A. C1 are the cylinders
fastened on the end of the connecting rod C by a pin which may either hold
them firm or allow them to move as on a pivot. I) is the socket or slotted guide
which receives the cylinders C1 pivotedly mounted on the lever S and is of
sufficient length to allow for the movement of the sieve boxes. S is the lever,
J is the pin upon which the lever works. G is the arm which carrys the worm-
wheel E by means of the pin I. H is the pin in the wheel E. As the wheel E
is revolved by the worm F the pin H working in the slit of the lever S moves
the socket D first in one direction and then in the other. The socket D working
loosely on the pin () accomodates the motion of the sieve boxes and lever.
It will readily be seen that by raising or lowering the grooves P by the
serews B1 B1 in which the rod A slides the brushes A1 are made to come in
contact with the sifting surface N more or less as desired and the brushes being

page_text: made to work backwards and forwards alternately keep the mesh of the sifting
surface clean.
When this method of cleaning is used on purifiers and sieves where it is not
necessary to carry it by the box or boxes the lever may be driven without the
worm and wheel if necessary.
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. A rod carrying a number of brushes or scrapers working in grooves
which is raised or lowered direct by four or more screws.
Second. A rod carrying a number of brushes or scrapers working in grooves
which is raised or lowered direct by four or more screws, the rod being slidden
alternately backwards and forwards at the same time being carried inside the
sieve box and underneath the sifting surface.
Third. The arrangement of sockets and cylinders which accomodate the motion
of the boxes and lever at the same time working the rod which carrys the brushes
or scrapers alternately backwards and forwards."
Fourth. Sieve cleaning apparatus constructed substantially as herein set forth.
