page_text: I, EDWARD PRITCHARD of No 2 Liardet Grove, New Cross in the County of
Kent, Ironplate Worker, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to construct a cinder sifter that shall be noiseless
in its action and easy to work. For this purpose I provide a box or bin by preference
of cylindrical shape, but which may also be rectangular or of other form, and which
has at top a circular opening across which at a certain distance down is fixed a bar,
carrying a central upright pin. Upon this pin is fitted a circular screen or sieve,
by means either of a central socket fixed to the sieve, or simply by a central hole
in the bottom of the sieve through which the pin passes, its upper end being made
to pass through a hole in a transverse bar at the top of the sieve. The vertical pin
has a boss or washer at bottom so as to keep the sieve a slight distance from the
transverse bar. To the upper edge of the sieve are fixed one or more upright
handles, by means of which a rapid to and fro motion can be imparted to the sieve
in order to produce the sifting action.
The top of the sieve is provided with a removeable cover so that after it has been
charged with cinders it can be closed in to prevent the dust from flying about.
When the box or bin is full, the sieve is lifted off, so that the bin can be emptied
of its contents, by turning it upside down, or when the bin is not portable, a door
may be provided in the side thereof for this purpose.

page_text: I, EDWARD PRITCHARD of No 2 Liardet Grove, New Cross in the County of
Kent, Ironplate Worker, 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:-
My Invention has for its object to construct a cinder sifter that shall be noiseless
in its action and easy to work. For this purpose, I provide a box or bin by pre-
ference of cylindrical shape, but which may also be of rectangular or of other form
and which has at top a circular opening across which at a certain distance down is
fixed a bar, carrying a central upright pin. Upon this pin is fitted a circular screen
or sieve, by means either of a central socket fixed to the sieve, or simply by a central
hole in the bottom of the sieve through which the pin passes, its upper end being
made to pass through a hole in a transverse bar at the top of the sieve. The vertical
pin has a boss or washer at bottom so as to keep the sieve a slight distance from
the transverse bar. To the upper edge of the sieve are fixed one or more upright
handles, by means of which a rapid to and fro motion can be imparted to the sieve
in order to produce the sifting action.
The top of the sieve is provided with a removeable cover so that after it has
been charged with cinders it can be closed in to prevent the dust from flying about.
When the box or bin is full, the sieve is lifted off, so that the bin can be emptied
of its contents, by turning it upside down, or when the bin is not portable, a door
may be provided in the side thereof for this purpose.
Fig. 1 of the accompanying drawing shews my before described improved cinder
sifter as applied to a cylindrical box or bin; Fig. 2 shews a plan of the same with
the cover removed. The cylindrical bin A is provided with a cross bar B having
fixed at its centre the vertical pin C with collar C. D is a circular sieve, having
a cross bar E at bottom and another E¹ at top, centrally in which are formed holes
through which the pin C passes, so that the sieve, resting upon the collar C¹ can
be moved to and fro upon the central pin with little or no friction. For imparting
such to and fro motion to the sieve vertical handles F are fixed to its upper edge;
or if desired such handles might be fixed on the cross bar E' nearer the centre. G is
a cover which is placed on the sieve after a charge of cinders has been placed
thereon, so that the dust is prevented from inconveniencing the operator during the
sifting process.
The sieve might also be made to fit with a socket H on the pin C, as shown at
Fig. 3 so as to have the bearing at top and protected from grit. When the bin A
is full, the sieve D is lifted off and the contents of A are discharged; or as before
stated, if the bin is of a large size or heavy, it may be provided with a door at
bottom for this purpose. The bin is provided with handles I for manipulating it,
or it may be mounted on wheels, and, if desired, swung on horizontal pivots for
the facility of tipping.
The bin may be made rectangular, polygonal, or any other shape than cylindrical,
the top being closed in, with the exception of a central hole for the reception of the
sieve. In this case, when arranged for tipping, the top plate of the bin surrounding
the sieve is also by preference made removeable.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is
1. Constructing cinder sifters of a sieve mounted at its centre on a vertical pin
carried by a bin or box into the top of which the sieve fits loosely, so that for sifting
cinders a to and fro motion can be imparted to the sieve upon the vertical pin,
substantially as herein described.
2. In combination with the bin A, with cross bar B vertical pin C, and collar C³,
the sieve D, rotatable upon the pin C and provided with a cover G, substantially as
herein described.
