I, JOSEPH HIGSON of Bella Street Danthill, Bolton in the County of Lancaster,
Brick Manufacturer, do hereby declare the nature of my said invention to be as
follows:
This invention relates to improvements in revolving riddles employed for riddling
ground clay, shale, rock, stone, cement and other analogous substances employed in
the manufacture of bricks, tiles, tuyeres, stoppers, nozzles, and others and consists in
means for heating the riddle to prevent the substances under operation choking the
meshes.
Under the riddle is mounted in any convenient manner a number of pipes which
may be heated by steam or gas. When arranged to be heated by steam the inlet is
attached to one of the end pipes which supplies the connecting pipes between itself
and the pipe on the opposite end; the outlet for steam and condensed water being
from the latter. In arranging for heating by gas the pipes are provided with suitable
gas burners and taps. The pipes are disposed to leave a cavity between each to
allow of the passage of the substance being riddled. If desired the whole can be
enclosed in a suitable casing and the substance led away down shoots in any convenient
manner.

Brick Manufacturer, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—

Fig. 1 is a side elevation of so much of a revolving riddle as is necessary to
illustrate my present invention Fig. 2 is a cross sectional elevation through
line A. B, and Fig. 3 a cross sectional elevation through line C. D.
Under the revolving riddle E are mounted the pipes F and M, which are held in
position by the stays G, or their equivalents, from the framework of the riddle, or
any other convenient position. The pipes F and M are connected by the pipes H
which extend the full length, or nearly so, of the riddle, and are disposed to allow
sufficient space for the passage of the substance under operation. The pipes H are
provided with the joints I to facilitate removal or otherwise. Stoam is conducted by
the pipe J to the pipe F, from whence it passes through the pipes H into the pipe M,
passing therefrom by the outlet pipe K. The heat rises from the pipes H and operates
against the meshes P of the revolving riddle E, keeping the same dry which
prevents the substance under operation choking the same.
In arranging my improvements for heating by means of ignited gas the pipes H
are provided with the gas burners O, as in Fig. 4, disposed so that the falling
substance will not choke the outlet of same. The burners are placed alternately on

page_text: each side as shown in Fig. 5. Gas is supplied to the pipe F by the pipe J; the
outlet pipe K shown in Figs. 1 and 2 in this case being dispensed with.
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
:-
For heating revolving riddles employed for riddling ground clay, shale, rock, stone,
cement, and other analogous substances, by either steam or gas, the construction and
arrangement of apparatus substantially as herein described and illustrated on the
drawings.
