PROVISIONAL SPECIFICATION.
Improved Arrangement of Apparatus for Riddling Cinders.
I, CHARLES HENRY SPENCER, of Cranworth Road, Sheffield, in the County of
York, Saddler, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to an apparatus chiefly adapted for domestic use, for
riddling cinders or ashes, the object being to expedite the operation and to avoid
the dust which is usually raised by the ordinary process.
The apparatus which is stationary is intended to be fixed to the inner wall of the
ordinary ashes pit, or the like place; an opening is made through the wall at a
convenient height for the ashes to be put through and a grate or screen is arranged
at a suitable angle underneath upon which the ashes and cinders fall and slide
down by gravity. At the bottom end and at a right angle or thereabouts with the
said grate, is a second grate also placed on an incline, and leading to a short spout
or shoot which projects through the wall, to conduct the riddled cinders to a
basket or other receiver.
The grates or screens above described are preferably covered or enclosed so as
to resemble or form a continuous knee shaped spout, and doors may be provided
both for the top openings and for the lower shoot.
When a quantity of ashes are thrown into the top opening they run down the
first screen, drop off the end, and run down the second screen by which time all
the dust and small ashes will have been separated and have dropped through into
the ashpit, and the large cinders will have passed into the shoot ready to be taken
away for use.

COMPLETE SPECIFICATION.
Improved Arrangement of Apparatus for Riddling Cinders.
I, CHARLES HENRY SPENCER, of Cranworth Road, Sheffield, in the County
of York, Saddler, 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 improvements in the construction or arrangment of
apparatus, chiefly for domestic use in the riddling of cinders or ashes, the object
being to expedite the operation, and also to avoid the dust which is usually raised
by the ordinary unpleasant process of raking the ashes upon a horizontal grate.
I have illustrated the invention in the annexed sheet of drawings.
Fig. 1, represents a side elevation of the apparatus according to one arrangement.
Fig. 2, Front of wall, showing entrance and exit.
Fig. 3, Elevation of second arrangement of apparatus.
Fig. 4, Plan of same.
This apparatus is intended to be attached to, or built in with the wall of the
ordinary ashpit, on the inside thereof; and communicating with the yard by means
of an inlet and outlet aperture, or it may be fixed in any other suitable position for
the intended purpose.
The ashes are to be thrown into the upper or inlet aperture in the wall and the

page_text: residue or riddled part will pass down the grates by gravitation and issues from a
shoot at the lower opening or exit and fall into the bucket or other receptacle
placed under it for that purpose, the dust and smallest cinders will pass through
the apertures in the grates and drop into the ashpit.:
In carrying out my invention on the plan illustrated in Figs. 1 and 2 of the
drawings, I make an opening A, at a convenient height through the wall B,
through which the ashes are to be thrown, and underneath the opening A, I make
another opening C: .
I prepare two grates D, and E, say for example, the upper one D, two feet long
by fifteen inches wide at the top end, and eight inches at the bottom end, and the
lower one E, two feet six inches long, by seven inches wide.
.T
I fix the upper grate D, inclining downwards from the opening A, and the
grate E, under the end of the grate D, and inclining in the opposite direction, its.
lowest end (which acts as a shoot) passing through the wall and projecting from
the lower opening C; into the yard.
The lower end of the grate E, being built into the wall, will be firmly fixed,
and able to support the lower end of the upper grate D, but they may also have
auxiliary supports, if desired from the wall such as F, or otherwise.
Sufficient room is left below the end of the grate D, to allow the free passage
of the cinders down the inclined grate E, and a flap door may be provided at C,
to cover the open end of the shoot if desired.
To prevent the dust and fine ashes falling from the grate D, upon the under
grate E, a ridged cover G, is used which throws off the dust into the ashpit.
According to a second arrangement, illustrated in Figs. 3 and 4, the lower grate E, -
is returned at a right angle to the upper grate, as seen in Fig. 4, passing through
the wall in a similar manner to that described in the former arrangement, the
opening A, through which the ashes are thrown may be either opposite at the end
as A, or at the side of the grate as A³, and the apparatus may be supported in the.
wall, or in any other suitable manner.
The grates may be entirely or partially covered over.
It will thus be seen that when the cinders and ashes are emptied through the top
opening A, they will slide or roll down the first inclined grate, by gravitation, the
bulk of the fine ashes passing through the openings; they will then be shaken and
separated by dropping upon the lower inclined grate, the remaining dust and fine
ashes passing through the openings, and the cinders making their exit at the end
of the projecting shoot; all the dust arising from the operation being kept inside
the ashpit, and thus enabling the riddling of ashes to be effected without labour
or annoyance.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same may be carried into practice, I declare that
what I claim is :-
:
f
1. An improved arrangement of apparatus for riddling cinders, (as applied to
ashpits or other places in contradistinction to portable hand worked cinder sifters
or boxes) consisting of an upper inclined grate fixed inside the wall of the ashpit
and also under an opening through which the cinders and ashes are to be thrown
in combination with second inclined grate fixed underneath and in line with the
first grate projecting at its top end to catch the cinders as they drop off the end
of the upper grate, and terminating at its lower end in a shoot returning through
the wall, to deliver the riddled cinders, substantially as hereinbefore described and
with reference to Figs. 1 and 2 of the drawings.
2. An improved arrangement of apparatus for riddling cinders (as applied to
ashpits or other places in contradistinction, to portable handworked cinder sifters
or boxes) consisting of an upper inclined grate fixed inside the wall of the ashpit
and under an opening through which the cinders and ashes are to be thrown in
combination with a second inclined grate fixed at the end of the first named grate

page_text: but at right angles or thereabouts, and terminating at its lower end in a shoot
passing through the wall, to deliver the riddled cinders, substantially as herein-
before described and with reference to Figs. 3 and 4 of the drawings.
Dated the 9th day of April 1891.
