PROVISIONAL SPECIFICATION.
Improved Sifter for Coal or Cinders.
I, THOMAS BRADLEY, 43, Raleigh Street, Nottingham, Innkeeper, do hereby declare
the nature of this invention to be as follows:-
:-
Each sifter consists of a case of wood or sheet metal, the lower part is somewhat
longer from the front to the back than the upper part, the case is provided at the
bottom with 4 trucks or runners and each side of the case with a handle to
facilitate removal.
The top of the case is formed in two parts, the back part is fixed, the front part
being hinged to it so that it may be turned back to open the case for the admission
of coal or cinders. Within the case just below the top an inclined board or metal
plate extends the whole width and about half way from the front towards the back.
Below the inclined board or plate extending the width of the case is a metal
screen or grating inclined at about, an angle of forty-five degrees from the back
towards the front. Across the width of the case a second screen or grating extends
at about the same angle from the front to the back of the case, a short distance
above the back lower end of the screen or grating, the back of the case projects to
form a receptacle for the sifted coal or cinders at the back of the receptacle the
case is closed by either a hinged or sliding door. At the front of the receptacle the
case is provided with a drawer opening at the front into which the dust from
the sifted coal or the ashes from the cinders fall.
To use the sifter the hinged or sliding door at the back of the case is closed, then
the lid at the top of the case is raised just sufficient to admit a small quantity of the
coal or cinders to be sifted, the lid being quickly closed to prevent dust rising.
The coal or cinders fall from the inclined plate onto the upper screen from which
they pass onto the lower screen into the receptacle at the back, from which they may
be removed when wanted for fuel. The dust or ashes fall through the two screens
into the drawer at the front of the case to await removal.
Dated this Twenty-first day of April 1890.

Improved Sifter for Coal or Cinders.
1. THOMAS BRADLEY, 43, Raleigh Street, Nottingham, Innkeeper, 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of an improved sifter.
Figure 2 a sectional view having the left side of the case removed, and
Figure 3 an enlarged view in plan of a screen or grating.
Each sifter consists of a case of wood or iron A having its lower part somewhat
longer from front to back than the upper part, the bottom of the case is provided
with four trucks or runners A' to facilitate removal.
The top of the case is formed in two parts, the back part is fixed, and has the
front part B hinged to it that it may be turned back to open the case for the admission
of coal or cinders.
Within the case below the top an inclined board or metal plate C extends the

page_text: whole width, and about half way from the front towards the back. Below the
inclined board or plate also extending the width of the case is a metal screen or
grating D inclined at about an angle of forty-five degrees from the back towards the
front, beneath which is a second screen or grating E extending from the front to the
back of the case. A short distance above the lower end of the screen or grating E,
the back of the case projects to form a receptacle for the sifted coal or cinders. The
receptacle being closed by a vertically sliding door F. At the front the case is
provided with a drawer G into which the dust from the sifted coal, or the ashes
from the cinders fall.
To use the sifter the sliding door F and the drawer G being closed, the lid B is
raised just sufficient to admit a small quantity of the coal or cinders to be sifted, the
lid being quickly closed to prevent dust or ashes rising.
The coal or cinders fall from the inclined board or plate onto the upper screen or
grating, from which they pass onto the lower screen or grating, then into the
receptacle at the back, from which they may be removed when wanted for fuel.
The dust or ashes fall through the two screens into the drawer at the front of the case
to await removal.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
The improved sifter for coal or cinders substantially as described and illustrated in
the drawings annexed.
Dated this Twelfth day of December 1890.
