Improvements in Boiler Furnaces.
I, ZEPHANIAH WILLIAM Baugh, of Bratt Street, West Bromwich, in the
County of Stafford, Grate Bar Manufacturer, do hereby declare, the nature of my
said invention to be as follows:-
My invention has for its object improvements in boiler furnaces and refers to the
means for assisting the combustion of the same which I effect in a very cheap,
simple, and efficient manner and without any material alteration to existing boilers
and furnaces. My improvements also include an arrangement for the easy removal
of ashes and dirt from under the grates of furnaces and boilers by which much
time and labor is saved.
In carrying my invention into effect in the case of furnaces I insert in the front
of the ash pit a cast iron plate in which I form a series of air tubes, holes, pipes,
or trumpets having an enlarged opening into which I direct a steam jet which blows
in the ash pit and passes up through the bars so that all unconsumed gas is thus
ignited and the fire above the bars increased in the intensity of its heat. The
tubes are made with feather flanges so as to be readily inserted in the outer plate
of the ash pit by which means they can be readily added to or taken away without
interfering with the tubes boiler or furnaces. I may use air both heated or cold
or steam either of which is equally adaptable.
For rendering the ashes more easy to remove than by the air tight door which I
form in the front plate of the ash pit, I form a drawer or pan at the centre of the
bottom of the pit into which the ashes are guided by inclined sides so that the
whole of the ashes can be withdrawn with the pan. The pan may project in front
of the front plate and have a curved bottom and cover so that upon opening the
cover the ashes may be scraped out.

COMPLETE SPECIFICATION.
Improvements in Boiler Furnaces.
I, ZEPHANIAH WILLIAM BAUGH, of Bratt Street, West Bromwich, in the
County of Stafford, Grate Bar Manufacturer, do hereby declare the nature of my
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has for its object improvements in boilers and furnaces and refers
to the means for assisting the combustion of the same which I effect in a very
cheap, simple, and efficient manner and without any material alteration to existing
boilers and furnaces. My improvements also include an arrangement for the easy
removal of ashes and dirt from under the grates of furnaces and boilers by which
much time and labor is saved.
In carrying my invention into effect in the case of furnaces I insert in the front
of the ash pit a cast iron plate in which I form a series of air tubes, holes, pipes,

page_text: or trumpets having an enlarged opening into which I direct a steam jet which blows
in the ash pit and passes up through the bars so that all unconsumed gas is thus
ignited and the fire above the bars increased in the intensity of its heat. The
tubes are made with feather flanges so as to be readily inserted in the outer plate
of the ash pit by which means they can be readily added to or taken away without
interfering with the tubes, boiler, or furnaces. I may use air both heated or cold,
or steam, either of which is equally adaptable.
For rendering the ashes more easy to remove than by the air-tight door which I
form in the front plate of the ash pit, I form a drawer or pan at the centre of the
bottom of the pit into which the ashes are guided by inclined sides so that the
whole of the ashes can be withdrawn with the pan. The pan may project in front
of the front plate and have a curved bottom and cover so that upon opening the
cover the ashes may be scraped out.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements and the mode
of carrying the same into effect.
Figure 1, is a general view of a furnace showing the application of my
improvements thereto.
Figure 2, is a vertical section on the line 1-2.
Figure 3, is a front elevation of the ash pit of an ordinary boiler showing the
application of my invention thereto.
Figure 4, is a vertical section through Figure 3.
Figure 5, is a part vertical section on line 1-2 when the pipes A are removed
and the opening closed.
In the application of my invention to furnaces I build in or otherwise insert at
the front part of the ash pit the cast iron or other suitable plate B in which I
form a series of holes in which are mounted the tubes, pipes, or trumpets A
having the enlarged openings a' into which the steam jets C are directed so as to
carry with it a quantity of fresh air which then passes up through the bars and
ignites the unconsumed gas and the intensity of the heat of the fire is thereby
increased. The tubes A are provided with the feather flanges a² by which means
they can be readily removed without interfering with the plate or furnace the nose
of the jets c' being made removable by being screwed upon the unions at while
in case of removal a cap or plug É is provided for closing the inlet. I may
combine this arrangement with the improved fire bars of my Patent No. 1434
of 1893 thus producing a perfect combustion as well as a considerable increase of
the intensity of the heat. I may direct air both heated or cold as well as steam
with the tubes A.
For rendering the ashes more easy to remove than by the air tight door F which
is formed in the plate B of the ash pit I provide the drawer or pan H at the centre
of the grate of the furnace the ashes being guided therein by the inclined sides or
aprons shown by dotted lines K so that the whole of the ashes can be removed by
the withdrawal of the pan H or the mouth h of the pan H may be made to
project beyond the face of the furnace so as to enable the contents to be readily
scraped out the bottom being curved at h³ to assist this. In this case the mouth is
covered by the removable or hinged plate J.
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 improvements in & relating to boilers and furnaces substantially as and
for the purpose herein set forth and shown upon the accompanying drawings.
2nd. In boilers and furnaces the mode of & means for introducing steam or hot
or cold air to the under side of the grate substantially as and for the purpose
herein set forth & shown.

page_text: 3rd. In boilers & furnaces the ash pan H substantially as and for the purpose.
herein set forth and shewn.
