COMPLETE SPECIFICATION.
A New or Improved Construction of Furnace for Burning Town's or
other Refuse.
I, WILLIAM HORSFALL of Camp Road Mills, Leeds in the County of York Engineer,
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 my invention is to construct furnaces for burning town or other
refuse, and to supply means for assisting in the burning of such refuse and products
of combustion thereof, so that the operation may be performed without any danger to
the health or inconvenience to the district in which the furnaces are placed.
In the accompanying drawings Fig. 1 is a front elevation and Fig. 2 a transverse
section through A. B Fig. 1 shewing my improvements.
To accomplish the above objects I employ the arched or dome shaped reverberating
furnaces A. A, these are formed of brickwork B. B, and provided with grate bars C. C
in the usual way. Longitudinally and between these furnaces I provide a boiler D,
being provided with the side flues E. E and bottom flues F. F.
I also provide the openings or passages G. G through which the products of
combustion pass from the furnaces A. A into the side flues E. E of the boiler D.
Below the grate bars C. Care provided the conical tubes H. H, or other passages,
which pass through the outer walls I. I and are open to the outer air by preference in
front of the furnace. The steam jets J. J are coupled to the boiler D at the top, these
terminating at their other ends K with taper mouths or nozzles L. L, through which
the steam is injected from the boiler D into the conical tubes H. H, and by so doing
sucks or forces air from the outside through the conical tubes into the chambers M. M
below the grate bars (. C, thence through the grate bars and into the fires, causing
thereby a very rapid combustion of the material forming such fire, without draught.
The products of combustion have to pass from the furnaces A. A through the
passages or openings G. G, the brickwork of the said passages or openings becoming
intensely hot will ignite or destroy the noxious gases or products of combustion as
they pass through. These heated products travel along the flues E. E and F. F of

page_text: the boiler, heating the water therein in so doing, thence to the chimney, passing
therefrom in a perfectly harmless condition, so that no inconvenience arises in the
neighbourhood where the furnaces are placed.
The boiler is by preference placed lengthwise of the furnaces so that any required
number of steam jets may be more conveniently applied.
The materials are fed to the furnaces A. A. through hoppers N N and openings OO,
such materials being tipped into them from an elevated stage or platform, or thrown
in by any convenient means; and in order to regulate the feed I provide the sliding
dampers or shutters P. P.
These sliding shutters are withdrawn or opened by
revolving cams R, from which the motion is conveyed through levers S and rods T,
to which the sliding shutters P, P are coupled at U. As the cams R revolve they
open the sliding shutters P. P by pressing outwards the levers S, and as they continue
to revolve they are released from the levers S and allow the shutters to be suddenly
or quickly closed by the action of the spiral springs V, thus stopping the supply to
the furnaces A. A.
Motion is imparted to the cams R through cone W and shaft X from any suitable
motor, and it is intended by this means to supply the material to the furnaces A. A
in the same ratio as the consumption or combustion of the material takes place in the
furnaces.
I provide a suitable clutch or other convenient arrangement for arresting the
movement of the cams R, so that the sliding shutters or dampers P. P can be closed
and caused to remain so for the purpose of removing clinkers and other like
obstructions in the furnaces A. A.
By the above arrangements the chimney used for conveying away the products of
combustion may be of a much less height than those now in use, in consequence of
the harmless nature of the products of combustion transmitted therefrom.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. The construction of arched or dome shaped furnaces A. A for causing a
reverberating effect on the heat and flame that may be produced from town's or other
refuse, such furnaces having small apertures or outlets G G for the passage of the
products of combustion, so arranged that no products or noxious gases can escape
without being burned and rendered harmless, substantially as herein set forth.
2nd. The arrangement of steam boiler D in combination with any required
number of furnaces A. A for the purpose of supplying steam, substantially as herein
set forth.
3rd. The arrangement and application of Steam jets J. J, in combination with
conical tubes H. H, or other openings or passages, for supplying air to the furnaces A. A,
substantially as herein set forth.
4th. The arrangement of hoppers N. N provided with dampers or shutters P. P
actuated by suitable mechanism, so as to allow of a supply of material, varying in
accordance with the rate of combustion, substantially as herein set forth.
5th. The general arrangement, construction and combination of the various parts
forming the means or apparatus for burning town's or other refuse, substantially as
herein set forth.
