PROVISIONAL SPECIFICATION.
Improvements in Cinder Sifters.
I, ALFRED CHARLESWORTH, of The Excelsior Trunk Works, Newton Heath,
Manchester, in the County of Lancaster, Trunk Manufacturer and Sheet Metal
Worker, do hereby declare the nature of this invention to be as follows:-
My said invention relates to improvements in the construction of domestic
cinder sifters and has for its object to produce a simple and efficient sifter
which can be easily manipulated and is not liable to get out of order.
In constructing a sifter in accordance with my invention I employ a light
metallic receptacle or sheet metal box which may be square, rectangular, or of
other suitable shape, such receptacle or box being designed for introduction
below the fire grate. The said receptacle or box is formed or provided with
bearings to receive trunnions or pivots carried by a perforated tray arranged
to sit in the said receptacle or box and to be rocked when required by means
of a handle or the like. The perforated tray is preferably of a curved formation
in cross section and may be either a mere perforated plate or be formed from
wire.
The sifter is introduced below the grate so that the cinder and ash from the
fire fall into the perforated tray which retains the cinders but permits the ashes
to fall into the receptacle beneath the separation of the cinders and ashes being
assisted as required by rocking the tray in its bearings by means of the handle.
The tray is capable of being readily lifted from its bearings so that the
retained cinders may be thrown back on to the fire and the ashes emptied from
the receptacle as required.
I may form the receptacle or box with suitable handles or parts to facilitate
transport.
A cinder sifter constructed as indicated is extremely simple and clean in

Improvements in Cinder Sifters.
I, ALFRED CHARLESWORTH, of The Excelsior Trunk Works, Newton Heath,
Manchester, in the County of Lancaster, Trunk Manufacturer and Sheet Metal
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 and accompanying drawings:-
:-
My said invention relates to improvements in the construction of domestic
cinder sifters and has for its object to produce a siniple and efficient sifter
which can be easily manipulated and is not liable to get out of order.
My invention will be clearly understood from the following description in
which reference is made to the annexed two sheets of drawings.

page_text: In the said drawings.
Fig. 1 shows an end elevation of my improved cinder sifter occupying a
position below the horizontal bars of an ordinary fire grate.
Fig. 2 is a vertical section of the cinder sifter.
Fig. 3 is a plan view.
Fig. 4 shows in plan view the cinder basket removed from the ash pan.
Fig. 5 is an end view of Fig. 4 taken at right angles.
Figs. 6 and 7 show slight variations in the form of cinder basket.
In constructing a sifter in accordance with my invention, I employ a light
metallic receptacle or sheet metal box a, which may if desired be formed with
one or more sloping sides a¹. This receptacle or box a, which may however be
of square, rectangular, or of other suitable shape, is designed for introduction
below the horizontal bars of the fire grate, as indicated in Fig. 1. The said
receptacle or box a is formed or provided with bearings b, to receive trunnions
or pivots c, carried by a perforated tray or wire work cinder basket d. This
cinder basket is arranged to sit in the said receptacle or box a and to be rocked
when required by means of a handle e or the like. Instead of seating the
trunnions or pivots in bearings they may be sustained by any other suitable
form of support. The perforated tray or cinder basket d, may be formed with
a square base and with sloping sides d¹, as shown in Figs. 1 to 5, or it may be of
a curved formation in cross section, as shown in Fig. 6 and 7. In this latter
case, the ends of basket may or may not be inclined, see Fig. 7.
I prefer to use a cinder basket formed from open wire-work, as shown in the
drawings, but I might, if so desired, employ a basket formed from a perforated
plate or plates or from expanded metal."
When using my improved sifter, such sifter, is introduced below the grate A,
so that the cinder and ash from the fire, fall into the perforated tray or cinder
basket d, which retains the cinder but permits the ash to fall into the receptacle a
beneath, the separation of the cinders and ashes being thus effected automatically.
When necessary, the separation of the cinder and ash may be assisted, by rocking
the cinder basket d in its bearings, by means of the handle e.
The cinder basket or tray d is capable of being readily lifted from its bearings
so that the retained cinders may be thrown back on the fire and the ashes
emptied from the receptacle as required.
A handle or ring g is provided by which the sifter may be readily withdrawn
from beneath the grate.
I may form the receptacle or box a with suitable handles or parts to facilitate
transport.
A cinder sifter constructed as indicated is extremely simple and clean in use
and can be produced at a low figure.
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―
The improved cinder sifter, consisting of a box or receptacle formed or pro-
vided with bearings or supports and adapted to receive a cinder basket or tray
formed or provided with trunnions or pivots and capable of being rocked in
such box or receptacle and readily removed therefrom, in the manner; for the
purposes, and substantially as herein described and shown.
Dated this 26th day of July 1900.
