Improvements relating to Heating Apparatus for Horticultural and
other Purposes.
I, CHARLES TOOPE of 1 Stepney Square, Stepney Green, London, E.
Horticultural Engineer, do hereby declare the nature of this invention to be
as follows:-
:-
My present improvements relate to the boilers or heaters used for efficiently and
economically heating greenhouses conservatories and the like as also offices bed
rooms &c. and in the means for and method of attachment and detachment which I
adopt for the circulating pipes; that is to say; referring to the boiler or heater
with a view more especially when an oil lamp is used for heating-to facilitate the
introduction and removal of the lamp with chimney attached, I form a vertical
opening extending upwards from the base of the lamp chamber of the heater and
partly through the heater itself, the total height of said opening or passage way
being sufficient to allow of the lamp with its chimney, being introduced bodily and
with facility, into or removed from the lamp chamber and lower portion of the heater.
The opening aforesaid would preferably be closed with either a hinged or a sliding
door, glazed to allow of inspection of the lighted lamp. Interiorally, a diaphragmi
extends across the cylindrical walls of the heater proper, at or about midway in the
height thereof, with central opening therein, for the passage therethrough, of the
products of combustion emitted at the mouth of the lamp chimney. The edge of
said central opening is burred up around its periphery to form a retaining channel
for water of condensation or any leakage water, which afterwards finds its way
through an opening provided in the diaphragm to a discharge pipe at the base of
the heater and descends into any convenient receptacle placed on the floor of the
greenhouse &c.
In order to ensure a greater amount of useful effect from the products of
combustion upon the walls of the heater before leaving same, I introduce a baffle
plate of any suitable shape, attached to the top interior wall of the heater and
disposed in front of the flue nozzle hereinafter referred to.
Secondly In reference to the circulating pipes-flow and return-Hitherto
these have been rigidly fixed or connected to the boiler or heater.
Now, according to my present improvements I make the connection in such a
manner as to allow of said pipes being readily disconnected from the heater when
required for repairs &c. and at same time without any risk of not ensuring a tight
joint when connected up in the manner hereunder stated.
In carrying out this part of my said invention I proceed as follows:-I employ
a nozzle fitted to the interior of the heater and over which I introduce the open
funnel-shaped end of the flue surrounding the flow pipe, the taper of said funnel
shaped end, being in the reverse direction to that of the nozzle over which it is
passed. A tight closure at point of junction is effected by the employment of a
round india rubber ring interposed between the inclined surfaces of the two fitting
parts aforesaid. Over and around the flue pipe is adapted the flow pipe, for the
heated water, the end of which takes into a second nozzle fixed to the exterior of
the outer wall of the heater. The method of effecting a perfect closure at this part
of the apparatus being the same as that above described for connecting the flue
pipe with the internal nozzle first above referred to. The end of the return
pipe is similarly adapted to another nozzle projecting from the outer wall of the
heater.

page_text: The means of attachment and detachment above described, may, with equal
facility and advantage, be employed at the "feeder" end of the apparatus.
The arrangement adopted under this second head of my invention possesses
several features of advantage, notably amongst which may be mentioned the great
convenience of packing into small space and the facility with which the parts may
be detached to allow of inspection and the carrying out of repairs &c.

I, CHARLES TOOPE, of 1 Stepney Square, Stepney Green, London, E.
Horticultural 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 :--
I have already in previous Specifications, viz. :-No. 2983 of A.D. 1885,
No. 4142 and 4694 of A.D. 1886 and No. 17413 of A.D. 1887, described various
improvements devised with a view to efficiently and economically heat greenhouses,
conservatories, and the like; as also offices, bed rooms &c.; and, and in the case
of my Specification No. 6816 of A.D. 1890, a device for purifying the air in
greenhouses &c. designed with a view, more especially, to annihilate the -toxic
action of fogs upon cultivated plants.
My present improvements relate to the boiler or heater itself, as also to the
means for and method of attachment and detachment which I adopt for the
circulating pipes.
And in order that my invention may be the better understood, I have appended
the accompanying sheet of drawings, in which
Figure 1, shews a sectional elevational view of my improved boiler, constructed
in accordance with my invention.
Figure 2, is a sectional view of the flow and flue pipes shewing the means which
I adopt for connecting them together.
Figure 3 represents a front view of my improved boiler, shewing the door or
opening for the passage of the lamps; and,
Figure 4 shews a plan view, with the top or cover removed.
Like letters of reference indicate corresponding parts throughout the several
views.
In accordance with my invention, and under the first head thereof; that is to
say, referring to the boiler or heater, with a view more especially-when an oil
lamp is used for heating-to facilitate the introduction and removal of the lamp
with chimney attached, I form a vertical opening extending upwards from the base
of the lamp chamber of the heater and partly through the heater itself, the height
of said opening or passage way being sufficient to allow of the lamp with its
chimney, being introduced bodily, and with facility, into or removed from the lamp
chamber, and lower portion of the heater. The opening aforesaid would preferably
be closed with either a binged or sliding door a, glazed to allow of inspection of the
lighted lamp.
Interiorally, diaphragms b, b' extend across the cylindrical walls of the heater
proper, and at or about midway in the height thereof, with central openings c, c¹
therein, for the passage therethrough of the products of combustion emitted at the
mouth of the lamp chimney. The edges of said central openings c, c¹ are burred up

page_text: around its periphery to form a retaining channel for water of condensation or any
leakage water, which afterwards finds its way through an opening provided in the
diaphragm b to a discharge pipe d at the base of the heater and descends into any
convenient receptacle placed on the floor of the greenhouse &c.
In order to ensure a greater amount of useful effect from the the products of
combustion upon the walls of the heater before leaving same, I introduce a baffle
plate e of any suitable shape attached to the top interior wall of the heater and
disposed in front of the flue nozzle f hereinafter referred to, of the flow pipe.
Under the second head of my invention, and in reference to the circulating
pipes, flow and return-hitherto these have been rigidly fixed or connected to the
boiler or heater. Now, according to my present improvements, I make the con-
nection in such a manner as to allow of said pipes being readily disconnected from
the heater when required for repairs &c., at the same time without any risk of not
ensuring a tight joint when connected up in the manner hereunder stated. In
carrying out this part of my said invention I proceed as follows:-I employ a
nozzle fitted to the interior of the heater, and over which I introduce the open
funnel shaped end of the flue pipe g, the taper of said funnel shaped end, being in
the reverse direction to that of the nozzle over which it is passed. A tight closure
at point of junction is effected by the employment of a round india rubber ring h
interposed between the inclined surfaces of the two fitting parts aforesaid. Over
and around the flue pipe is secured, by means of connecting stays i, the flow pipe j
for the heated water, the end of which takes into a second nozzle k fixed to the
exterior of the outer wall of the heater. The method of effecting a perfect closure
at this part of the apparatus being the same as that above described for connecting
the flue pipe with the internal nozzle first above referred to. The end of the return
pipe is similarly adapted to another nozzle m projecting from the outer wall of the
heater.
The means of attachment and detachment above described, may, with equal
facility and advantage, be employed at the "feeder" end of the apparatus.
The arrangement adopted under this second head of my invention possesses
several features of advantage, notably amongst which may be mentioned the great
convenience of packing into small space and the facility with which the parts may
be detached to allow of inspection and the carrying out of repairs &c.
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 :-
1. In boilers or heaters for horticultural and other purposes, the means which I
employ, to enable the lamp to be introduced or removed with its chimney attached,
substantially as herein described and shown in the accompanying sheet of
drawings.
2. In boilers or heaters for horticultural and other purposes the improved
arrangement of securing the flue, flow and return pipes thereto, substantially as
herein described, and shown in the accompanying sheet of drawings.
3. The improvements relating to heaters or boilers for horticultural and other
purposes, substantially as herein described and shown in the accompanying sheet of
drawings.
