for the Invention of "IMPROVED BOILER OR APPARATUS FOR HEATING
CONSERVATORIES, GREENHOUSES, AND OTHER HORTICULTURAL OR
STRUCTURES."

Sealed the 4th June 1878, and dated the 6th December 1877.
PROVISIONAL SPECIFICATION left by the said John Watson at the Offico
of the Commissioners of Patents on the 6th December 1877.
JOHN WATSON, of St. Albans, in the County of Herts. "IMPROVED BOILER OR
APPARATUS FOR HEATING CONSERVATORIES, GREENHOUSES, AND OTHER HORTI-
CULTURAL OR OTHER STRUCTURES."
My Invention consists of an improved boiler or apparatus specially useful for
heating conservatories, and horticultural and other buildings, such as churches,
chapels, and so forth.
In carrying out my Invention I adopt substantially the following arrangements :——
The boiler or apparatus is composed or formed of various parts or picces, generally
ten, more or less. One part or piece is formed in shape similar to the ordinary
saddle boiler, but the end is placed upwards, thus in effect forming in shape thus n
Inside the space is placed a second chamber, running the whole or nearly the whole
length of the space. This second chamber is connected to the first portion by pipe
or pipes, the number being according to the length of boiler. The first chamber at
the lower part thereof has a pipe which forms the return into the second chamber.
At the upper part of the second chamber there is connection by pipe or pipes with
a third chamber, which is placed above the said second chamber. Into this third
chamber a flow pipe is inserted.
In some cases however this third chamber can be dispensed with, and the flow is
direct into the second chamber, and from thence into the heating pipes; or a coil of
pipe may be inserted in the upper part of second chamber to act as part of boiler
and flow pipe.
The whole of the parts are encased in brickwork, and the fire-bars are underneath
the boiler.

page_text: The action is as follows:-When the three chambers or parts are used water is
admitted at the lower part of the saddle portion of the boiler, thence by pipes from
the first chamber into the second chamber, and is heated as it circulates. The water,
thence, as heated, flows into the third chamber by pipe or pipes from the second
chamber, and passes by pipe or pipes in communication with the said third chamber 5
into the series of pipes used for heating purposes.
The special points of my Invention are, the placing of the second chamber, as
described, with connections by pipes to the first chamber and communicating
therewith.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Watson in the Great Seal Patent Office on the 6th June
1878.
JOHN WATSON, of St. Albans, in the County of Herts. "IMPROVED BOILER OR
APPARATUS FOR HEATING CONSERVATORIES, GREENHOUSES, AND OTHER HORTI-
CULTURAL OR OTHER STRUCTURES."
My Invention consists of an improved boiler or apparatus specially useful for
heating conservatorics, and horticultural and other buildings, such as churches,
chapels, and so forth.
In carrying out my Invention I adopt substantially the following arrangements:-
The boiler or apparatus is composed or formed of various parts. One part is formed
somewhat similar to a horse-shoe placed horizontally. Inside the space thus afforded
is placed a second chamber, running the whole, or nearly the whole, length of the
space. This second chamber is connected to the first portion by pipe or pipes
according to the length of boiler. The first chamber, at the lower part thereof,
has a pipe which forms the return into the second chamber; or the return can bo
made independent of the first chamber. At the upper part of the second chamber
there is connection by pipe or pipes with a third chamber, which is placed abovo
the said second chamber. Into this third chamber a flow pipe is inserted.
In some cases however this third chamber can be dispensed with, and the flow
made direct into the second chamber, and from thence into the heating pipes; or a
coil of pipe may be inserted in the upper part of second chamber to act as part of
boiler and flow pipe.
The whole is encased in brickwork, loaving proper flues as practised in boiler
setting, and the fire-bars are underneath the boiler.
In action (when three chambers or parts are used) water is admitted at the lower
portion of the horse-shoe part of the boiler, thence by pipes from the first chamber
into the second chamber, or (as shown in the Drawings) into the third chamber
direct, and samne is heated as it circulates. The water issues from the second
chamber by pipes, as shown, and thence as heated flows into the third chamber,
passing by pipe or pipes in communication with the said third chamber into the
series of pipes used for heating purposes.

page_text: Fig. 1 is a front view of my improved boiler or apparatus; Fig. 2 is side view,
partly in section; Fig. 3 is plan with third chamber shown in dotted lines;
Fig. 4, isometrical view of second chamber.
In the said Drawings A denotes the first chamber; B, pipe or pipes connecting
same with chamber C; D, chamber placed inside second chamber, and con-
municating with chamber C by pipes d, d', d; F, flow pipe; G, return pipe or
pipes into chamber A; H, return pipe to centre chamber D; J, fire-bars; K, plug
for the purpose of cleaning chamber D of sediment and such like when required;
L, heat space, through which tho products pass and issue out after circulating round
the whole of the apparatus by flue ; M, brickwork in which the boiler or apparatus
is set.
The action of the arrangements shewn in the Drawings is as follows:-The boiler
or apparatus being charged with water, and the fire lighted, the heat acts upon the
chambers, the water flowing into the chamber A and passing up as heated by pipes B
into the third chamber C. The water from the chamber D in the meantime as
heated passes by pipes d, d, d, into the said third chamber C, and thence by flow
pipe Finto the heating pipes (not shown in the Drawings), and after circulating
through same issues again into the apparatus by the return pipes G and H, and the
same action is repeated.
In some cases the centro chamber D may be used by itself for heating purposes,
and when so used pipes d', ds, are not used, but to pipe & I usually attach a fitting
shown by dotted lines (Fig. 4). The water as heated flows by pipe d, and thence
through fitting into pipe or pipes, and after circulating through same is conveyed
back into the chamber by return H.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improved Boiler or
Apparatus for Heating Conservatories, Greenhouses, and other Horticultural or
other Structures," substantially as herein-before set forth and described, and
illustrated by the accompanying Drawings, and especially the use or adoption of the
centre chamber D, herein-before described, in boilers or apparatus for heating con-
servatories, greenhouses, and other horticultural or other structures.
In witness whereof, I, the said John Watson, have hereunto set my hand
and seal, this Fourth day of June, in the year of our Lord One thousand
eight hundred and seventy-eight,
