Improvements in the Firing of Steam Boilers for the Purpose of
Generating Steam.
THOMAS HOWARD BLAMIRES and WILLIAM BLAMIRES Manufacturers
Phoenix Mills Leeds Road Huddersfield do hereby declare the nature of this
invention to be as follows:-.
This improvement applies to the adaptation of the movement of the furnace doors
to actuate or move, open or shut, automatically the valves or taps which supply steam
to furnaces for the purpose of blowing the fires, the object being to raise steam in
such furnaces as Meldrum's and others of a similar character by means of a forced
draught, or in other similar places where an increased combustion of the fuel is
required.
This we accomplish by connecting or coupling the furnace doors to the valves or
taps governing the steam supply, by means of a shaft and bevels, or directly with
a shaft and pinion wheels, or levers, links or a quadrant motion, or other similar
mechanical device may be employed in order to get the required movement of
governing the steam valves or taps by means of opening or closing the furnace
doors or other similar places where steam is employed for creating a forced draught;
either where the steam is admitted on top of the fires or underneath the fire grates
or bars, so that the steam is not 'blowing during the time the furnace doors are
open and the fires are being stoked or supplied with fuel; as previously this has
been a great drawback inasmuch as the fires have blown in the stoker's face when
in the act of supplying fuel or stoking the furnaces, thus rendering the possibility
of serious accidents arising to the fireman.
This improvement may be applied whether the injected steam is admitted above
the grate bars, as well as where admitted underneath the grates or fire bars, or even
where admitted in both ways.
The taps or valves are operated upon automatically by the action of opening and
closing the furnace doors, thus dispensing with the present method of opening and
shutting off the steam by hand during the firing and stoking or otherwise attending
to the fires which necessitates the furnace doors or other openings for the supplying
of fuel to the furnaces being open.
A modification of this may be also employed in combination with any mechanical
stoker when and where steam is injected into the furnaces for the purpose of
increasing the combustion of the fuel.

invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This improvement applies to the adaptation of the movement of the furnace
doors to actuate or move, open or shut, automatically the valves or taps, which
supply steam to furnaces for the purpose of blowing the fires, the object being to
raise steam in such furnaces as Meldrum's and others of a similar character by
means of a forced draught, or in other similar places where an increased combustion
of fuel is required.
This we accomplish by connecting or coupling the furnace doors to the valves or
taps governing the steam supply, by means of a shaft and bevels, or directly with
a shaft and pinion wheels, or levers, links, or a quadrant motion, or other similar
mechanical device may be employed in order to get the required movement of
governing the steam valves or taps, by means of opening or closing the furnace
doors or other similar places where steam is employed for creating a forced draught;
either where the steam is admitted on top of the fires, or underneath the fire grates
or bars, so that the steam is not blowing during the time the furnace doors are
open and the fires are being stoked, or supplied with fuel, as previously this has
been a great drawback inasmuch as the fires have blown in the stoker's face when
in the act of supplying fuel or stoking the furnaces, thus rendering the possibility
. of serious accidents arising to the fireman.
This improvement may be applied whether the injected steam is admitted above
the grate bars, as well as where admitted underneath the grates or fire bars, or
even where admitted in both ways.
The taps or valves are operated upon automatically by the action of opening and
closing the furnace doors, thus dispensing with the present method of opening and
shutting off the steam by hand during the firing and stoking or otherwise attending
to the fires, which necessitates the furnace doors or other openings for supplying
of fuel to the furnaces, being open.
A modification of this may be also employed in combination with any mechanical
stoker when and where steam is injected into the furnaces for the purpose of
increasing the combustion of the fuel.
In order that our said invention may be properly understood and carried into
effect we will now proceed to describe the drawings hereunto annexed.
A represents the furnace door which is swung or opens upon a pin or stud B
passing through the boss or lugs of the door and is fastened thereto. At
the end of this pin or stud is a bevel whee! C 1. gearing with another bevel
wheel C 2. fastened to the stud or spindle of the valve D, which admits or passes
the steam down the steam pipe S to the jets or blowers G 1. and G 2., which
direct the steam and air into the furnace for the purpose of creating a forced
draught.
The said level wheel C 1. is moveable, preferably upon a fast key bed and
Jocked with a thumb screw K, so as to be readily put in and out of gear as may
be required, and also by gearing a tooth forward or backward, more or less steam
may be admitted at will.
It will thus be seen that by opening the furnace door A the movement is com-
municated through the bevel wheels C1 and C2. to the spindle of the valve D,
and that the steam is automatically cut off by the act of opening the furnace door,

page_text: thus dispensing with having to shut off the steam by hand at every operation
of firing or adding fuel to the fires, stoking, or in any other way attending to the
fires.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is-
'
1. An automatic device or arrangement whereby the steam and air is cut off
automatically by the action of opening the furnace door, during such time as the
fireman is stoking, or fuel is being added to the fires; instead of having to cut off
the steam and air by hand as in the present method previous to firing, stoking, or
otherwise attending to the fires, in order to prevent the danger and inconvenience
of the back action of the flames from flashing out in the stoker's face, and thus
preventing any risk of accidents arising therefrom; substantially as herein
illustrated and described.
