Improvements in Apparatus for Sifting or Riddling Cinders or other
Materials or Substances.
WILLIAM CONGREVE and RICHARD BROWNSWORD, of 34 & 36 Lower Hillgate,
Stockport, in the County of Cheshire, Ironmongers, 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 :-
The object of our invention is the construction of a portable durable and simple
apparatus whereby cinders or other materials or substances can be more effectively
and readily sifted or riddled than heretofore has been the case.
And in order that our invention may be more fully understood, we have caused to
he appended hereunto one sheet of drawings marked with letters of reference indi-
cating like parts in the various figures.
Fig. 1. is a cross section and Fig. 2. part side view and part longitudinal section, of
our improved apparatus, for riddling or sifting.
Our invention consists principally in the employment inside of a suitable casing, of
a perforated rotary barrel or riddle of angular section, the lid of which when opened,
serves as a tray to facilitate the removing, out of the same, of the sifted or riddled
material or substance.
In carrying out our invention we form a casing a, preferably of metal, the bottom
of which we furnish with legs b, each end with a door c, d, openings c¹, d', and the top
with two lids o, f.
Inside of the said casing a is arranged to rotate in bearings e, e, suitably secured
thereto, the perforated barrel or riddle g, preferably of square section.
This perforated barrel or riddle g, consists of two wooden end plates g¹, gl, to the
inside of which, we suitably secure respectively a metal cross piece h formed in the
middle with an axle h', which are made long enough to respectively project through
the said plates gl, gl, and the bearings e, e, to receive a handle i.
The body of the barrel or riddle g, suitably secured onto the said end plates g², g',
we form of woven wire, and the lid 92, suitably hinged thereto, of perforated sheet
metal and with a convenient form of fastening, such as a loop and pin .
In the drawing the lid 92, is shown as closed, in full lines, and open, in dotted lines,
in which, latter case when serving as a tray to facilitate the removal of the material or
substances, it is permitted to rest on a ledge a¹, formed by means of an angle iron
fitted inside the casing a, between the outlet opening c¹ and barrel or riddle g, at an
incline.
The top of the casing a we furnish with two lids o, f, suitably hinged thereto, the
edges of which are bent over so as to insure a tight fit with the top of the casing a.
The lid, when open, see dotted lines, serves to permit of charging the barrel or
riddle 9, with the material or substance to be sifted or riddled and the lid o, see also
dotted lines, to permit of opening the barrel or riddle lid g², for the purpose of facili-
tating the emptying thereof through the outlet opening c.
The latter is furnished with a hinged door c and a lip c², by means of which latter
and a rake, the riddled material or substance is conducted, from the barrel or riddle g
and tray or lid g², into a suitable receptacle.
The material or substance which passes through the barrel or riddle 9: is permitted
to fall below the same onto the bottom of the casing a, from whence it is removed by
means of a rake, through an opening & formed in the respective end of the casing a
and furnished with a sliding door d.
In order to retain the barrel or riddle g in its proper position when charging or
emptying the same, we provide a pin k, which we insert into a hole 1, formed in the
side of the casing a, and holes m & m¹, formed in the end plates g¹, 91, of the barrel

page_text: Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, we declare that
what we claim is :-
"In apparatus for sifting or riddling cinders or other materials or substances."
1st. The general arrangement, construction, and adaptation of parts, operated sub-
stantially as and for the purpose set forth.
2nd. The employment inside of a suitable casing a, of a perforated rotary barrel or
riddle of angular section, the lid g², of which when opened serves as a tray to
facilitate the removing out of the same, of the sifted or riddled material or substance,
substantially as and for the purpose specified.
