PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Fuel to Steam Boiler
and other Furnaces.
I JOHN WHITEHEAD of 233 Bury Road Tottington near Bury in the County of
Lancaster Mechanical Engineer do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in that class of fuel supplying and
distributing apparatus for which I applied for Letters Patent No. 11082 on
the 16th day of July 1890 and consists of an improved means of conveying the
fuel along the distributing trough described in my former Specification and of
feeding the same to the several discharged funnels in front of the furnaces.
In carrying out my invention I dispense with the endless belt or creeper hitherto
employed and substitute therefor one or more shafts or their equivalent along the
trough arranged to move about by suitable means. to the said shafts or their
equivalent I attach a series of scrapers or projections which serve to move the fuel
along the trough until it is guided by gates or projections extending at a more or
less acute angle (described in my former Specification) through, openings into the
funnels in front of the furnace.
These shafts or their equivalent with a series of scrapers attached thereto may be
fixed in suitable bearings and moved backward and forward by cranks or cams at
one or both ends of the said shafts.
Dated this 11th day of November 1892.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Supplying Fuel to Steam Boiler
and other Furnaces.
I JOHN WHITEHEAD late of. 233 now of 102 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 :-
This invention relates to improvements in that class of fuel supplying and
distributing apparatus for which I applied for Letters Patent Number 11082 on
the 16th day of July 1890 and consists of an improved means of conveying fuel
along the distributing trough described in my former Specification and of feeding
the discharge funnels in front of the furnaces. In carrying out this invention I
dispense with the endless belt or creeper hitherto employed and substitute therefor
one or more rods longitudinal with the trough to the said rod or rods I attach a
series of scrapers or projections which in their motion serve to move the fuel along
the trough (distributing trough until it is guided by gates or projections (in the
distributing trough) through openings in the funnels through which the fuel passes
into the furnaces these rods are operated by means of cranks, eccentrics cams or
their equivalent.
In order that the foregoing may be better understood I file herewith 1 sheet of
drawings in which Fig. 1 is a longitudinal elevation Fig. 2 a plan view of the
apparatus in these figures the same letters of reference indicate the corresponding
parts with the exception of a part of the apparatus indicated by the letter g on
Fig. 2. The letter D represents a metal trough (placed in front of two furnaces)
along which the fuel is conveyed from a suitable hopper or receptacle to the

page_text: openings indicated by E E the gates g g show how the fuel is guided into the
openings and how the required amount of fuel can be turned into each opening by
regulating the gates. The letter a indicates a metal rod to which is attached a number
of scrapers or projections which serve to move the fuel along the trough D. The
letter 6 shows a crank to which is attached one end of the rod a. Towards the
other extremity of the rod is a slot F into which the rod moves. The motion of
the crank moves the rod a backward and forward besides raising and lowering it
so that in one half of a revolution of the crank b the scrapers or projections are
lowered and dip into the fuel and push it forward. In the other half of the
revolution of the crank the rod a is raised and the scrapers or projections in their
return journey are lifted above the fuel. I have shown in the annexed drawings one
metal rod to which is attached a number of scrapers or projections operated by
means of one crank. More rods than one may be employed in one trough arranged
either side by side or one succeeding another and a crank may be attached to one
or both ends of each rod. Where it is necessary to work a rod or rods in a parallel
line with the trough I employ a connecting rod to each rod. I hinge each scraper
or projection. to the rod so that they come in contact with and force the fuel
along the trough in one direction and in the other direction they slip over
the fuel.
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 combined apparatus substantially as described and shown hereinbefore
and in the accompanying drawings for the purpose set forth.
2nd. A metal rod or rods to which are attached scrapers or projections fitted to
a trough or passage capable of moving backward and forward either in a rise and
fall manner or in a parallel line as described and shown herein before for the.
purpose set forth.
Dated this 12th day of August 1893.
