Improvements in Apparatus for Supplying and Distributing Fuel to
Steam Boiler and other Furnaces.
1, JOHN WHITEHEAD of 233 Bury Road, Tottington near Bury, County of
Lancaster, Engineer do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improvements in that class of fuel supplying and
distributing apparatus for which I obtained Provisional Protection No. 11082
and dated the 16th day of July 1890 and is also applicable to other fuel supplying
apparatus and consists in the employment of an improved metallic spreader affixed
by preference inside the furnace over the dead plate and opposite to the nozzle
which delivers the small fuel under the influence of the steam or other blast into
the furnace. This spreader is so formed with a sharp vertical edge tapering off
like a plough share that it divides the current of fuel and causes the same to be
delivered on each side of the spreader and whereby the distribution of the fuel over
the entire surface of the fire is more perfectly ensured.
Deted this 8th day of December 1890.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Supplying and Distributing Fuel to
Steam Boiler and other Furnaces.
I JOHN WHITEHEAD of 233 Bury Road Tottington near Bury in the County of
Lancaster 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 an apparatus for supplying and
distributing fuel in steam boiler and other furnaces in a more effective form than
those at present in use and which may be used in conjunction with an apparatus for
supplying fuel for which Letters Patent has been granted to me No. 11082 and
dated 16th July 1890 or in conjunction with any other automatic or semi-automatic
apparatus for feeding furnaces.
To accomplish this I fit in front of the furnace a receptacle or shoot into which
the fuel is supplied. Attached to this receptacle or shoot is a tube fitted by
preference above the furnace door which leads into the furnace and through which
the fuel is delivered into the furnace by means of a steam or blast pipe. Inside of
the furnace over the dead plate and opposite to the end of the tube from which the
fuel is delivered into the furnace I affix an angular shaped spreader which is so
formed with a vertical edge tapering off like a plough share that it divides the
current of fuel and causes the same to be delivered on each side of the spreader and
whereby the distribution of the fuel over the entire surface of the fire
perfectly ensured.

In order that the foregoing may be better understood I send herewith a sheet of
drawings in which
Fig. 1 shows a side view of a furnace with my apparatus fitted to Fig. 2 shows a
plan view of my apparatus.
In these figures a indicates the receptacle or shoot into which the fuel is supplied
b indicates the tube through which the fuel is delivered into the furnace by means

page_text: of the steam or blast pipe d. e indicates a side view and e² a plan view of the
spreader opposite to the end of the tube. The current of fuel as it is delivered
from the tube comes in contact with the edge of the spreader e and is thereby
split and directed in, an angular direction on both sides of the spreader as
indicated by the shape of the spreader shown at e² on Fig. 2.
.
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
1st. The combined apparatus substantially as described and shown hereinbefore
and in the accompanying drawings for the purpose set forth.
2nd. The combination of a spreader with a tube or passage into the furnace from
which fuel is delivered and by means of the spreader the fuel is distributed
substantially as shown and described hereinbefore and in the accompanying
drawings for the purpose set forth.
Dated this 7th day of September 1891
JOHN WHITEHEAD.
