JOHN INGHAM TAYLOR, of Manchester, in the County of Lancaster. IMPROVE-
MENTS IN APPARATUS FOR SIFTING CINDERS, ALSO APPLICABLE IN THE CONSTRUC-
TION OF APPARATUS FOR OTHER RIDDLING, SORTING, SEPARATING, OR MIXING
PURPOSES."
In carrying out my Invention, say, as applied to a cinder sifter, I mount a
cylindrical, segmental, or other suitable shaped frame upon a horizontal axis, and
so as to be capable of making an entire or partial revolution inside a casing. This
frame constitutes the riddle, and for this purpose is provided with a wire
mesh or other riddling surface. Access is obtained to the inside of this frame to
introduce the cinders and ashes through an apperture which is closed by a pair of
hinged taps so connected to a spindle mounted inside the hollow extremities of the
horizontal axis that by turning such spindle more or less such flaps may be opened
or closed or set open and adjusted at any desired distance apart to regulate the
discharge of the contents, and which contents may thus be sorted or separated,
according to sizes, to the greatest nicety. Instead of a hinged flap or flaps the
apperture may be closed by means of a curved plate attached at each end to an arm
radiating from the horizontal axis, and thus capable of a fraction of a revolution so
as to bring the same opposite to the apperture, and thus to cover the same or to be
open more or less, according to requirement.
The casing of this apparatus is provided with a hopper for feeding the material

page_text: into the riddling frame, and with a pair of drawers or receptacles, the lower one to
receive the ashes or small dust, and the upper one the clean and sifted cinders.
The action of this apparatus may be described as follows:-The axis carrying the
riddling frame projects through the casing at either extremity, and there, at one
or both ends, is by preference provided with a toothed pinion gearing with a
segmental toothed wheel or quadrant, from which projects an arm or lever which
is capable of a rocking motion by the hand of the operator. The riddling frame
being thus geared is caused to revolve or partially revolve, and so its contents
become sifted or riddled without any dust escaping, the hopper and drawer
appertures being closed with properly rebated joints.
It will be readily apparent that this construction of apparatus is suitable not
only for riddling purposes, but for sorting or separating garden mould, lime, gravel,
seeds, fruits, and other material or things requiring to be sorted in various sizes,
and that by substituting an enclosed recptacle for the riddling frame an apparatus
may be constructed in accordance with this Invention suitable for mixing purposes,
the interior of such receptacle being provided with projections to assist the mixing
operation.

JOHN INGHAM TAYLOR, of the City of Manchester. "IMPROVEMENTS IN APPA-
RATUS FOR SIFTING CINDERS, ALSO APPLICABLE IN THE CONSTRUCTION OF APPARATUS
FOR OTHER RIDDLING, SORTING, SEPARATING, OR MIXING PURPOSES."
Fig. 1 is an end sectional view of a cinder sifter constructed in accordance with
my Invention, and Figs. 2 and 3 represent respectively an end and partial side
view (upon an enlarged scale) of parts of Fig. 1.
In carrying out my Invention I employ a cylindrical or other suitably shaped
frame or cage A to contain the material to be sifted, and which is mounted on
horizontal axes G inside a suitable casing J. This frame A is constructed of a pair
of solid wooden ends A' supporting between them a wire mesh or other riddling
surface B. Access is obtained to the inside of this frame to introduce the cinders
and ashes through an aperture C which is closed by means of a curved plate D
attached at each end to an arm E radiating from the spindle F passing through the
main horizontal axis G to the outside where a wheel handle G' is provided, by
means of which such spindle may be turned a fraction of a revolution so as to,
bring the plate D opposite to the aperture C, and thus to cover the saine entirely,
or to move the same to the position indicated by the dotted lines in Fig. 2 when
the aperture is required to be wide open; for instance, in introducing or with-
drawing the material, or to any intermediate position, and in either of which
positions the curved plate may be locked by means of a stud H projecting from the
inside of the wheel G¹ caused to enter one of a series of holes formed in a
segmental plate I carried by the pinion N.
The casing J of this apparatus is provided with a hopper K for feeding the
material into the riddling frame (the outer surface of which is brushed and kept
clear by the weighted brush K' guided up and down in vertical slots), and with a
pair of drawers or receptacles, the lower one. L to receive the ashes or small dust,
and the upper one M the clean and sifted cinders. The action of this apparatus
may be described as follows:-The axis carrying the riddling frame projects through
the casing at either extremity, and there, at one or both ends, is by preference
provided with a toothed pinion N gearing with a segmental toothed wheel or
quadrant O mounted on the fixed stud O', and from which projects an arm or
lever P which is capable of a rocking motion by the hand of the operator. The
riddling frame being thus geared is caused to revolve or partially revolve, and so
its contents become sifted or riddled without any dust escaping, the hopper and
drawer apertures being closed with properly rebated joints.
Instead of the curved plate D being employed the aperture C may be closed by
a pair of hinged flaps Q, as seen in Fig. 4, in which case such flaps are connected
by connecting rods R to a crank S upon the central spindle which passes through
the hollow axes, as hereinbefore described, and thus by turning such spindle more
or less such flaps may be opened or closed, or set open and adjusted at any desired
distance apart to regulate the discharge of the contents, and which contents may
thus be sorted or separated according to sizes to the greatest nicety.
In the modification illustrated by Fig. 5 the riddling frame A is shewn of a
different form, and is provided with transverse bars "a "which tend not only to
strengthen the frame, but serve to carry the material round a certain distance, and
then by letting it fall assist in the riddling operation. Instead of drawers being
employed one above the other a hinged flap b is applied to divert the dust to one
side bi, and the clear cinders or other material to the other side b³. And it will be
apparent that each of these sides of the apparatus could be provided with a separate
drawer or other receptacle. Fig. 6 shews my improved cinder sifter applied to an
carth closet, by means of which the cinders may be sifted, using the dust which

page_text: falls into the pan or pail c for disinfecting purposes, whilst the clear cinders are
retained and capable of being diverted into a drawer d.
In Figs. 7, 8, and 9 I illustrate another method of operating the riddling cage so
as to inpart either half or any less portion of a revolution to the same. The
mechanism consists of a slotted arm e fixed to and radiating from the main axes f
which carries the riddling cage. Motion is communicated to the cage by means of
the lever g, which is provided with a roller h taking into the slotted arm, so that
when the lever g is oscillated to and fro the cage is caused to rock with a variable
motion owing to the different curves described by the working parts, as indicated
by the dotted lines in Fig. 9.
It will be readily apparent that this construction of apparatus is suitable not
only for riddling purposes but for sorting or separating garden mould, lime, gravel,
seeds, fruits, and other material or things requiring to be sorted in various sizes,
and that by substituting an enclosed receptacle for the riddling frame an apparatus
may be constructed in accordance with this Invention suitable for mixing purposes,
the interior of such receptacle being provided with projections to assist the mixing
operation.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods with which I am acquainted for carrying
the same into practical effect, I wish it to be distinctly understood that I do not
confine myself to the precise details, relative proportions, or dimensions of the
various parts of the apparatus hereinbefore described, and illustrated on the accom-
panying Drawing, as the same may be considerably varied without departing from
the Invention, and that I claim,-
1st. The general construction and arrangement of apparatus for sifting, riddling,
or sorting, substantially as herciu before described, and illustrated on the accom-
panying Drawing.
2nd. Mounting a cage, riddle, or sieve on horizontal axes, and operating the same
substantially as and for the purposes herein before described, and illustrated on the
accompanying Drawing.
3rd. The combination and arrangement of mechanism for opening and closing
and adjusting the degree of opening of the door or doors of apparatus mounted on
horizontal axes, substantially as and for the purposes hereinbefore described, and
illustrated on the accompanying Drawing.
In witness whereof, I, the said John Ingham Taylor, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our Lord One
thousand eight hundred and seventy-nine.
JOHN INGHAM TAYLOR. (L.S.)
