PROVISIONAL SPECIFICATION.
Improved Apparatus for Consuming Smoke, and Economising Fuel
in Steam Boilers and the like.
I THOMAS MASON, 73, Clun Road, in the City of Sheffield, in the County of York
Stoker, do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to provide an apparatus whereby the smoke
generated by steam boilers is consumed by the boiler fire, and thus causing a
considerable saving in fuel.
In order to attain this object I connect a tube or pipe of suitable material and size,
to the top of the boiler-preferably to the front near the top-this tube or pipe I
carry downwards as low as the top of the fire hole and then into the fire hole for
about 6 inches, to the end of this pipe I connect a perforated T piece so as to reach
across the fire, in this T piece I make the holes so that they will throw the jets on
the fire bars at a suitable angle, this pipe is provided with a valve to regulate the jets.
I continue the before mentioned pipe down the front of the boiler (or an additional
one) as low as the ash hole and carry it on the top thereof under the fire bars a little
past the bridge and turn it round so that the end of it formes an arch in the fire hole
above and a little behind the bridge, this end I also perforate-the holes being at a
suitable angle.
At a suitable distance from the front of the boiler I connect a perforated arm,
T piece or other suitable nozzle on to the said pipe running under the fire bars to
send jets of steam through the fire bars at a suitable angle. At the other end of the
said pipe-a little in front of the bridge-I attach an other similar nozzle the jets
from the said nozzlès can also be regulated by a valve out side the boiler.
The effect of the jets of steam blowing through the holes under the fire bars is to
lift the fire, whilst the jets above the fire force the smoke and particles of carbon
down on the fire thereby effectually consuming the smoke and saving fuel.
In case a boiler has more than one fire hole I provide similar apparatus
to each.

I THOMAS MASON, 73, Clun Road, in the City of Sheffield in the County of York
Stoker do hereby declare the nature of this invention and in what manner the same
Price 8d1

page_text: is to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of the present invention is to provide an apparatus whereby the smoke
generated by steam boilers is consumed by the boiler fire, and thus cause a saving in
fuel as well as completely doing away with the disagreeable and unhealthy
consequences of the clouds of smoke usually emitted from such fires.
I will explain, with reference to the accompanying sheet of Drawings in what
manner I carry out my invention. The same letters of reference indicate
corresponding parts in all the figures.
Fig. 1. is a longitudinal section. Fig. 2. is a cross section through line K of a
boiler fitted with my invention. Fig. 3 is a modification of the arch E over the
bridge F. A Fig. I, is a length of ordinary inch steam pipe connected to the top
of the boiler end or other convenient part of the boiler top, this pipe I carry
downwards as low as the top of the fire hole and take a branch into the fire box for
about 6 inches, to the end of this branch 1 connect a perforated arm or T piece or
nozzle B, reaching across the fire. In this T piece I make the holes so that they
will throw the jets inwards over the fire. I provide a valve C to this pipe to regulate
the jets which I prefer to keep blowing a little to keep the pipe cool. I continue the
said pipe down the boiler front as low as the ash hole and carry it at the side of the
top thereoff, under the fire bars as shown at D. I continue it through the base of
the bridge under the fire bars and then turn it up so that it forms an arch at E round
the top of the fire box a little behind the bridge F this bend or arch I also perforate,
the holes being at a suitable angle but I get the best results when the jets are thrown
behind the bridge.
At a suitable distance, about 6 inches from the front of the boiler I connect a
perforated arm G or other nozzle on the said pipe running under the fire bars to send
jets of steam under the fire at any suitable angle inclining inwards. I am aware
that steam jets have been in use for consuming smoke, both above the fire at the
front end and under the front of the bars, and I do not lay claim merely to the use of
steam either under the front of the fire bars or above the front of the fire. At the
other end of the pipe D I attach, a little in front of the bridge, a perforated arin H
and I find that the best results are obtained when the jets are so arranged that they
blow through an aperture I in the base of the bridge just under the bars.
also provide a wall L or other means to baffle the fumes after passing beyond the
usual bridge so that the before mentioned jets H under the far end of the ash hole
and those from the perforated arch E may inore effectively cleanse the fumes of the
particles of carbon &e.
I do not confine my silf to arch the pipe at E as shown in Fig. 1. and Fig. 2, but I
may make it any other shape so long as it is arranged so that all or nearly all the
fumes from the fire passes through the jets of steam.
I provide a valve at J to regulate the jets under the fire bars. I also provide a
throttle valve or shutter to the aperture I which I close when the jets are turned off
by means of a rod passing through the ash hole to the front of the boiler.
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 :-
First. In steam boilers and the like, blowing steam on the smoke and fumes in
front or behind the bridge, as and for the purpose herein described and shown on the
drawings,
Second. In steam boilers and the like, blowing steam jets throw the aperture I in
the base of the bridge as, and for the purpose described and shown.
Third. In steam boilers and the like the combination of the jets H and the
areh F as and for the purpose shown and described,

H and F substantially as and for the purpose herein described and shown on the
accompanying sheet of Drawings.
