I, HENRY JOSEPH ALLEYN, of the City of Dublin, Justice of the
Peace, do hereby declare the nature of the said Invention for " IMPROVE-
MENTS IN OR CONNECTED WITH FURNACES AND OTHER FIRE-PLACES OR HEATING
APPARATUS, IN FEEDING AND STOKING SAME SO AS TO CONSUME SMOKE AND NOXIOUS
GAS OR AIR, AND IN THE PRODUCTION, PURIFICATION, AND UTILIZATION OF HOT AIR
AND HOT BLASTS, AS WELL AS THE HEATING OF WATER and OTHER LIQUIDS," to be
as follows:-
My Invention consists of an improvement in the production of hot air
or hot blasts in furnaces, in sheeting the cold or hot blast furnace or
ordinary furnace connections and hot air receivers in whole or in part
with water or other liquid; in consuming or purifying the smoke and air
by what may be termed central firing combined with the use of lime or
other like purifying agent, arranged in a chamber or chambers into and
through which the hot air is driven; in economizing fuel by the con-
sumption of limestone, chalk, clay, water, or other material combined
with coal or otherwise; in the application or utilization of the hot air so

page_text: produced and purified to heating and drying corn, grain, seed, textile
fabrics, and other goods; to the heating and evaporation of liquids in
breweries, distilleries, and other works and places; to the raising of steam
and the production of gas; and to motive power purposes in general.
Also in the adaptation or application of the Invention in whole or in
part to warming rooms and buildings, and to existing boilers, furnaces,
grates, and other heating apparatus.
In carrying out my Invention I construct one or more furnaces filled
or nearly so with coal or (with or without coal combined) with lime-
stone, chalk, or other material through which I introduce a blast of cold
or hot air or vapour by means of a fan, blowing engine, or other ordinary
contrivance.
The air after passing through the furnaces may receive a further blast
of hot or cold air or gas, it is then conducted to the chamber containing
lime or other purifying agent as herein-before mentioned, and thence is
utilized as may be required either by direct or indirect application for
any of the heating purposes herein-before indicated.
The furnace or furnaces as well as the connections and hot air
receivers arc entirely or partly surrounded or cased with water or other
liquid. The fuel is supplied to the furnace or furnaces either from the
side or top by a peculiarly shaped scoop, which is so constructed as to
deposit the fresh fuel in the layer or bank, and during the process of
deposit to remove the ashes and cinders or other waste. The scoop
referred to is a cylinder partly opened or closed at top with a wedge
faced extremity and opening longitudinally to deposit fuel, and this
cylinder or a slight modification of the same may be used in conjunction
with other fire dividing apparatus, and it is inserted at any intermediate
point in the furnace, the pressure of insertion at the same time forcing
over the exit of the furnace the ashes, cinders, or other refuse.
