PROVISIONAL SPECIFICATION.
An Improved Stove for Warming Greenhouses, Conservatories,
Rooms, or the like.
I HENRY THOMAS FENLON of 8 Tudor Street Blackfriars in the City of
London E.C. Engineer do hereby declare the nature of this invention to be as
follows:-
This my invention relates to an improved stove for warming greenhouses con-
servatories rooms or the like and my invention consists of a stove comprising the
following parts the whole being combined and arranged substantially as hereinafter
described and set forth.
My improved stove consists of a hot water circulating stove with respective flow
and return pipes and a small boiler which is heated by means of a gas jet or other
suitable means the fumes and products of combustion from which are caused to
traverse a flue in which condensation takes place and thus no noxious fumes escape
into the outer air.
My improved stove is constructed substantially in the following manner.
The boiler which consists of a small cylindrical closed chamber is connected
by means of small tubes with the pipes or tubes which are of any convenient
length and dimensions through which the water circulates. The said circulating
pipes are arranged preferably one above the other and the heated water from the
boiler is discharged through a long connecting tube into the upper of said pipes
through which it flows through a bend into the lower pipe from which it returns to
the boiler through a short tube. Thus a continual circulation of the water takes
place. The said circulating pipes are supported at their ends in two vertical
standards which are formed hollow.
The boiler is enclosed in a double casing which is open at the bottom and has a
flue leading from the upper part thereof the said flue passing vertically through
the lower circulating pipe into the upper therein being branched longitudinally
throughout its length and the open ends being inserted in the hollow standards.
During the passage of the fumes and heated gases through the said flues they
become cooled and condense against the sides of the hollow standards a tray being
provided to receive the moisture.
The space between the flow and return circulating pipes is enclosed by suitable
plates which are preferably curved or bent inwards the said plates serving to
confine the heat and prevent the cooling of the said pipes by the contact of the
cold air the heating surface being also by this means greatly increased.
Dated this 20th day of March 1894.

I HENRY THOMAS FENLON of 8 Tudor Street Blackfriars in the City of
London E.C. 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 my invention relates to an improved stove for warming greenhouses con-
servatories rooms or the like and my invention consists of a stove comprising the
following parts the whole being combined and arranged substantially as hereinafter
described and set forth.
My improved stove consists of a hot water circulating stove with respective
flow and return pipes and a small boiler which is heated by a gas jet or other
suitable means the fumes and products of combustion from which are caused to
traverse a flue in which complete condensation takes place and thus no noxious
fumes escape into the outer air.
In order that my invention may be more readily understood reference is made to
the accompanying drawings wherein like letters indicate corresponding parts in
.each of the figures and in which
Fig. 1 is a vertical section partly in elevation shewing the preferable arrangement
of parts forming the stove when adapted to be heated by gas.
Fig. 2 is a perspective view of the stove.
Fig. 3 is a vertical section shewing a modified disposition of the flues which may
be adapted to a stove heated by an oil lamp and
Fig. 4 shews another modification hereinafter described.
The boiler A consists of a small cylindrical closed chamber which is connected
by means of small tubes a, b, with the pipes or tubes which are of any convenient
length and dimensions through which the water circulates. The said circulating
pipes are arranged preferably one above the other and the heated water from the
boiler is discharged through the long connecting tube a into the upper of said
pipes A through which it flows thence through a bend or communicating pipe B
into the lower pipe C from which it returns to the boiler through a short tube b.
Thus a continual circulation in the direction of the arrows in Fig. 1 takes place.
The said circulating pipes A' & C are supported at their ends by vertical
standards D as shewn the said standards being hollow and of any approved shape.
The boiler A is enclosed in a double casing e which latter is open at the bottom
and has a flue E leading from the upper part thereof through the lower circulating
pipe C into the upper A' therein being branched longitudinally throughout its
length and the open ends being inserted in the hollow standards D.
In the modified form shewn in Fig. 3 adapted for use with an oil stove the
flue E is branched in the lower pipe C and the fumes traverse the said branch,
the hollow standard, and a separate flue E' running the whole length of the upper
pipe A'.
In Fig. 4 the stove is shewn provided with a base of cast iron or other material
there being an inclined passage through the said base for the fumes. The fumes
and products of combustion arising from the source of heat employed in each and
all of the forms become cooled during their passage through the several flues
and condense against the sides of the latter a tray or other receptacle being used
to receive the moisture.
The space between the flow and return circulating pipes is enclosed by suitable
plates which are preferably curved inwards as shewn the said plates serving to

page_text: confine the heat and prevent the cooling of the said pipes by the contact of the
cold air the heating surface being also by this means greatly increased.
The said curved plates may be used in combination with any stove having
separate flow and return pipes and I do not wish to confine their use to a stove of
the construction described.
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. A stove for warming greenhouses conservatories rooms or the like con-
structed arranged and operating substantially as described and illustrated in the
accompanying drawings.
2. The combination with a stove for heating purposes having flow and return
circulating pipes of radiating plates enclosing the space between said pipes
substantially as described.
