HEATING STOVES
Year: 1885

page_text: I AMBROSE HUDD SMITH Plumber & gas fitter Victoria Street Clifton in the
County of Glouster I do hereby declare the nature of my invention for HEATING
STOVES to be as follows:-
:―
This Invention relates to certen gas or coke stove for heating greenhouses &
rooms with les consumption of gas or fuel, thearfore affecting a grate reduction in
gas or fuel by this arangement a small greenhouse can be heated with one small jet
of gas for any length of time without any attenchion or trouble.
In carring out this invention I construct a stove made of fire-clay or any other
materiel, the stove is made about 4 feet in hight & sise so that the heated surface
shal not to break the stove or pipes or burn or scorch the air at the base of the
stove is a gas burner or fire or any inflamable oil in front of this burner is a
junction piece & on this junction is fixed a glas dore made of iron this dore shuts
againts a inderubber flange this makes the dore perfectly air-tite & thus it prevents
the fumes or smoke from coming in the compartment whear the stoves is fixed the
glas dore enables a person to see to regulate the fire without opening the dore at
the side of this dore is a junction pipe conected whith the exturnel air to feed the
gas or fire the heated air after pasing into the bodd of the stove returns to the
outlet pipe about 9 in from the base of the stove & then pas round the compart-
ment in horisontle pipes slightley elevated in length so as to exaust & radiate the
hole of the heat in the compartment whear the stove is fixed & before it pas away
into the outlet pipe about 12 to 18 in above inlet pipe with a horisontle bend.
By this means I get the hole of the heate in the compartment whear the stove
is fixed pure & free from smell this effects a greate saving in gas or fule & by the
pipes pasing out at the same aspect & a little above each other prevents any back
draugh.

I, AMBROSE HUDD SMITH Victoria Street Clifton in the County of Gloucester
Plumber and Gas fitter 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 :-
The object of this invention is to produce more perfect combustion of the gas
than has hitherto been practicable thereby obtaining increased heating power
combined with a reduced consumption of gas.
This I effect firstly by superheating the gas previous to its combustion.
Secondly By so conducting the air requisite to support such combustion to the
burners that it is drawn up from immediately beneath them in a powerful blast.
Thirdly By hermetically closing the opening round the door of the stove so that
no leakage of air can exist when the door is closed.
The figures of reference in the following description refer to corresponding
figures in the accompanying drawings.
To carry out my invention I take a gas stove made either of fire clay or other
auitable material or metal and fit the same with an inlet pipe (1) which serves to
convey fresh air into the body of the stove-One end of such air inlet is fitted in
the base of the stove while the other extremity is carried to the outside of the
building and fitted with a cap or terminal-A slot (2) is formed in such air inlet
pipe to, allow of the air current being drawn up therethrough as previously
described I then fit the stove with a gas supply pipe (3) furnished with a suitable
gas cock (4) and connected to the gas main at any convenient point-The inner
end of such gas supply pipe terminates in a bend (5) which fits into the before
mentioned slot and has mounted thereon one or more suitable gas burners (6)-
Such burner or burners is or are fixed immediately over such slot so that when
the gas is lit the vacuum created by its combustion causes the air to rush in
from below through such slot in a powerful blast and feed the flame thus
supporting combustion without diminishing or preventing the radiation of the heat
produced as is the case when such flame is fed either from the top or sides in the
ordinary manner-On referring to the accompanying drawings it will also be seen
that the gas supply pipe is so fitted that it passes over the burners whereby the
gas as it is conducted to the burners passes over the flame thereby becoming
superheated and expanded By such superheating perfect combustion of the gas is
obtained while its heating power is greatly augmented at the same time that
owing to its expansion a considerable economy in the quantity of gas consumed
is effected.
I fit the upper part of a stove with an outlet or radiating pipe (7) placed at any
convenient height and having any suitable number of coils or bends through which
the heated air generated in the body of the stove circulates before passing away
into the outer air thus producing perfect combustion of the heat contained
therein―The outer extremity of the outlet pipe is carried into the external air in
the same aspect as the air inlet pipe thereby preventing any back draught.
In order to render the bottom of the stove air tight and thus further assist in
producing perfect combustion I fix an india rubber or other suitable elastic
washer (8) round the opening in the front of the stove to which the door is fitted
so that when the door is shut against such elastic washer the opening is hermeti-
cally closed thus effectually preventing all leakage of air into the body of the stove-

air inlet pipe thereby increasing the intensity of the flame and so aiding perfect.
combustion.
It will be obvious that the air current being limited by the size of the slot only
sufficient air is introduced into the body of the stove to admit of its being slowly
circulated through the pipes thus allowing of its heating properties being thoroughly
exhausted before passing away through the outlet pipe.
One important advantage resulting from my improved construction of heating
stove is the totally obviating the unpleasant and poisonous fumes which have
hitherto been generated by them when in use.
In order to allow of the gas flame being easily regulated I make a sight hole (9)
in the body of the stove in any convenient position and fit the same with a mica
or other suitable transparent or semi transparent shade so that the height of the
flame can be seen therethrough and raised or lowered as desired. If preferred
however this sight hole may be dispensed with..

improvements. A is the body of the stove-B the cylindrical mouth piece whereto
the door C is hinged.
Fig. 2 is a detail view of the air inlet pipe shewing the slot therein.
Fig. 3 is an elevation of the lower part of such a stove partly in section clearly
shewing my improvements fitted thereto.
Fig. 4 is an external elevation of such lower portion shewing the door C removed
therefrom so as to clearly shew the elastic washer round the door opening.
My invention possesses the essential advantages of great utility and economy-
It is particularly applicable to heating apparatus, for churches entrance halls,
warehouses, public buildings and elsewhere firstly owing to the entire absence of
all unpleasant and unhealthy fumes when in use and secondly owing to the
economy effected in the quantity of gas consumed--It may also be applied with
advantage to gas cooking apparatus and other gas stoves.
I do not claim any of the several parts constituting my improvements in gas
stoves as novel in themselves.
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,
1. Fitting a gas stove with a slotted air inlet pipe (1) gas inlet pipe (3) union (4)
burner or burners (6) outlet pipe (7) and elastic washer (8) respectively arranged
combined and fitted all substantially in the manner and for the purposes
hereinbefore described and shown.
2. If and when required in combination with the improvements recapitulated in
and claimed by the foregoing claim formning a suitable sight hole in a gas stove
and fitting such sight hole with a mica or other suitable transparent or semi
transparent shade substantially in the manner and for the purposes hereinbefore
described and shewn.
