PROVISIONAL SPECIFICATION.
Improvements in Hot Water Boilers.
I, GEORGE TEMPLEMAN, Plumber and Hot Water Fitter, of Planque, Catel,
Guernsey, Channel Islands do hereby declare the nature of this invention to be as
follows:-
A reliance saddle boiler with waterway end with flues each side half way through.
Bottom of flues level with fire bars, then running lengthwise through centre of
sides of boiler and out at the front, over the sides and top to chimney at back of
boiler. Both flues at sides of boiler are equal to the size of the opening in front
of saddle running the same height right through boiler. Width of flues running
through to be according to the size of boiler. Flues outside saddle brickwork with
arch turned over top. Small boilers to have one flow one return; large ones one
flow two returns. To have five soot boxes for cleaning flues, two each side at
bottom of saddle one on top of saddle in front.

COMPLETE SPECIFICATION.
Improvements in Hot Water Boilers.
I, GEORGE TEMPLEMAN, of Planque, Catel, Guernsey, Channel Isles, Plumber
and Hot Water 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 :-
My invention relates to improvements in hot-water boilers.
The object of my said invention is to construct, for use in green-houses, conserva-
tories, and the like, an improved boiler of the saddle type wherein the hot gases
from the fire are circulated over the interior and exterior heating surfaces in such a
manner that their heat is utilized more completely than in boilers of this kind as
hitherto usually constructed. The chief feature of my said invention is the
provision of flues in the water space of the boiler.
In order that my invention may be clearly understood I will now proceed to
describe the same with reference to the accompanying drawings, wherein
Figure 1 is a longitudinal central section of my improved boiler and its setting.
Figure 2 is a plan of the boiler and setting, in section on the line X X of
Figure 1.
Like letters indicate corresponding parts throughout the drawings.
A is the boiler-setting, which has an arched central cavity A' therein, extending
from the front nearly to the rear.
B is the boiler which is placed in the upper portion of the said cavity. It is of
the saddle type, having double walls B with a water space between them, and is
preferably made of wrought iron. One end of the saddle is closed by a transverse
hollow chamber B2, with a water-space therein which forms a continuation of the
water-spaces of other portions of the saddle. The space C enclosed by the
saddle forms the furnace and is provided with fire-bars C₁ below which is
an ashpit D. The side walls of the cavity A' support the boiler, and are
slightly set back above the ashpit, so that external side-flues A² are formed
at the sides of the boiler. A³ is a clearance space between the top of the
[Price 817

page_text: boiler B and the top of the cavity A', which forms an upper exterior flue with
which the external side-flues A² communicate. The upper flue A³ communicates
by the channel A₁ with a chimney in which a suitable damper is provided. The
front ends of the flues A2 and A³ are closed by the throat plate E and by the brick-
work of the setting, in which soot-doors A' are provided. B³ is an outflow neck for
the passage of heated water out of the boiler. B B are inflow necks for the
passage of water thereinto. F F are internal flues one of which is formed in the
water space in each side of the boiler; each flue extends for nearly the whole
length of the boiler, but does not pass through the front and rear ends. F¹ is an
opening in the inner wall of the boiler near the rear end of each flue to afford
communication between the interior of the flue and the furnace C. F2 is an opening
in the outer wall of the boiler near the frout end of each flue, to afford communica-
tion between the interior of the flue and the external flues A².
The products of combustion of fuel burnt on the bars Cheat the interior of the
boiler B and pass from the furnace C through the openings F' into the internal side-
flues F which they traverse from the rear to the front, where they pass through
openings Finto the external side flues A2. From the side flues A2 the products of
combustion rise into the upper flue A³ wherein they flow over the top of the boiler
to the outlet A*
It will be seen from the foregoing description that the water in the water-spaces
of the boiler is heated from the inside and outside of the boiler as well as from the
internal flues, and also that the circulation of the products of combustion is arranged
so that a very considerable heating-effect is obtained from them before they pass
away from the apparatus.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is
1. A hot-water boiler of the saddle type with side flues in the water spaces thereof
substantially as hereinbefore described for the purposes specified.
2. The combination with such a boiler of a setting wherein external flues are
arranged substantially as herein before described for the purposes specified.
3. The heating-apparatus constructed and arranged substantially as herein-
before described with reference to the accompanying drawings, for the purposes
specified.
