Year: 1888

page_text: I, ABRAHAM HENTHORN STOTT of Wykebam Place Middleton Road Oldham in the
County of Lancaster Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus for feeding fuel to marine and
other steam boilers and furnaces by mechanical means and secondly to improvements
upon a former invention for which Letters Patent were granted to me in the year 1887
No. 11401. The drawings illustrating the improvements are marked from letter A
to Q hereunto annexed.
At A and B are section and elevation of boiler at C is coal-breaker which is attached
to elevator D by a shaft which rotates both coal-breaker and elevator by worm and
wheel at letter by which the coal is conveyed from coal-bunker M into hopper at E
which coal is carried from hopper E by tubes and screws at J which screws are rotated
by worm and wheel at M to feeding tubes I which tubes conduct the coal onto the
front part of the furnace; at letters F are circular revolving hollow bars with screws
on the periphery with solid fixed bars between the rotating bars, which rotating bars
are worked by worn and wheel at O, and as the combustion goes on the fire is moved
to the back end of the furnace and the ashes drop onto the end of the ash-remover
at P which ash-remover is worked by worm and wheel at Q and the ashes are delivered
onto the ash-conveyer H which will be worked by rope-pulley K and thereby carried
to tank or ash-holder.

I ABRAHAM HENTHORN STOTT of Wykeham Place Middleton Road Oldham 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 apperatus for feeding fuel to Marine and
other Steam Boilers and Furnaces by mechanical means and secondly to improvements
upon a former invention for which letters Patont were granted to me in the year 1887
No. 11401. The drawings illustrating the improvements are marked from letter A
to Q and are annexed to the Provisional Specification accepted July 14th 1888 which
I intend to be annexed to this Specification.
At A and B are section and elevation of Boiler at C is coal breaker which is attached
to elevator D by a shaft which rotates both coal breaker and elevator by worm and
wheel at letter L by which the coal is conveyed from coal bunker M into hopper at E
which coal is carried from hopper E by tubes and screws at J which screws are rotated
by worm and wheel at N to feeding tubes I which tubes conduct the coal onto the
front part of the furnace. At letters F are circular revolving hollow bars with screws
on the periphery with solid fixed bars between the rotating bars which rotating bars
are worked by worm and wheel at O and as the combustion goes on the fire is moved
to the back end of the furnace and the ashes drop on to the end of the ash remover
at P which ash remover is worked by worm and wheel at Q and the ashes are delivered
onto the ash conveyer H and thereby carried to truck or ash holder.
Having now described the nature and object of my said invention together with the
manner in which the same is to be or may be performed or carried into practical effect
I wish it to be understood that I claim as my invention the following viz.
Firstly I claim the general arrangement whereby I am enabled to deliver the coal
and fuel from the coal and fuel bunker or tip into and on to the fires thereby saving
both fuel & labour.
Secondly I claim the mechanism of the coal breaker and combination of elevator
with the said coal breaker herein before described and illustrated at C. C.
Thirdly I claim the hollow circular revolving bars illustrated at F.
Fourthly 1 claim the ash remover and the ash conveyer.
