PROVISIONAL SPECIFICATION.
Improvements in Apparatus used in Heating Buildings.
I JOHN WATSON of St. Albans, in the County of Hertford, Florist, do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is an improvement in that class of boilers for which I
have obtained Letters Patent No. 1400 so that it may be readily adapted to heating
by gas and more especially by means of the gas and burner described in the
specification of S. M. Biddison No. 124678.
In carrying out my invention I enclose the boiler within two cases on three sides,
one being outside the other and kept about one inch apart by means of perforated
strips of metal inserted between. This forms a hot air chamber from which the heated
air passes into the building, in which the arrangement is fitted; while the water
contained in the boiler heated by means of the gas flows through the usual hot-water
heating pipes, thus warming one or more room or rooms by hot air and other rooms,
conservatories, green-houses, etc. by hot water.
Various ventilation holes are formed in the outside casing to admit air to promote
combustion and in some cases a door or doors are fitted for lighting and cleaning
purposes.
In some cases I conduct both the hot-air and hot-water into the same building or
room as for instance when applied to a greenhouse, or conservatory, where the
arrangement is placed outside by preference."
It is obvious that these improvements are applicable to all suspension boilers.

COMPLETE SPECIFICATION.
Improvements in Apparatus used in Heating Buildings.
I, JOHN WATSON, of St. Alban's, in the County of Hertford, Florist, do hereby
declare the nature of my said invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to the class of boilers and heating appliances for which I
have obtained Letters Patent No. 14008; and the object of my present invention is
to effect further improvements in such apparatus, so that it may be adapted to the
use of gas and other fuel, and more especially to the fuel and burner described in the
Specification of S. M. Biddison, No. 12,46785
In carrying out my present invention I enclose my suspension boiler in a doublo
casing, one case being within the other, and secured at suitable distances apart by
means of perforated strips of metal. The space between the two cases forms a hot
air chamber, from which heated air may be caused to enter the building in which the
apparatus is fitted; while the circulating water from the boiler flows through the
usual hot water pipes to the same or any other building. Thus the hot air from
the casing may be applied as a means of heating one or more room or rooms, and
the hot water pipes may be applied in heating other rooms or conservatories,
greenhouses &c.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.

in the wall of a building, and Fig. 2 is a longitudinal sectional elevation of the
same. Fig. 3 is a section on the line 1-2 of Fig. 2, and Fig. 4 is a section on
on the line 3-4. Fig. 5 is an enlarged section of my improved atmospheric
burner.
a a is the outer casing. bb is the inner casing. c is the boiler, having a
tubular flue d running through the same from end to end. e is an atmospheric
gas burner, supplied with gas by the pipe and with air by the chamber g (Fig. 5).
The chamber is formed as shown in Fig. 5, to prevent the gas lighting back.
The air enters as shown by the arrow and mixes with the gas, uninfluenced by
draughts and adverse currents, the combustion being at all times steady and constant.

from the boiler, and is the return pipe. m is a perforated bottom to the inner
case, to admit air to the burner, through the holes n. 0 is a movable plate,
which may be perforated or solid, or may have a movable plate fitted thereto for
closing the openings. is the flue, which is preferably carried through the wall
to the outside of the building. is the outer door, and s is the inner door.
t is a baller to prevent the passage of the heated gases direct to the flue
pipe d.
The heated gases pass upwards on each side of the boiler to the space ¹, from
whence the heated gases descend to the flue pipo d, in the direction of the arrows
to the flue p.
Instead of using ordinary gas fuel as above described, I sometimes fit the appa-
ratus with Biddison's patent burner, in which case the outer air is shut off from
the combustion chamber.
I sometimes place a dish or vessel of water at for the purpose of moistening
the heated air, on its passage to the building.
I also sometimes line the inside of the inner casing with fire-clay, or other suitablo
non-conducting material, as shewn by dotted lines in Fig. 4; Lor T iron being
riveted or otherwise fitted to the case for supporting the same.
It is obvious that the apparatus may be otherwise fitted, and that the front
plate a with its door and other fittings may be dispensed with; the flue being
carried to any convenient outlet.
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 the construction of heating apparatus, the improved method of mounting
boilers, of the description aforesaid, in a double casing, for the purpose of
obtaining the circulation of heated air, in addition to and in combination with the
circulation of heated water, substantially as herein before described and illustrated by
the drawings.
2. In combination with heating apparatus as aforesaid, the application and use of
gas fuel, substantially as herein before described.
3. In combination with heating apparatus as aforesaid, the application and use of
the improved atmospheric gas burner, substantially as herein before described and
shown in Fig. 5 of the drawings.
4. In combination with heating apparatus as aforesaid, the application and use of
Biddison's patent burner and fuel, substantially as herein before described.
5. The general construction combination and arrangement of the several and
respective parts, together forming my invention of improvements in heating apparatus,
substantially as herein bofore described and illustrated by the drawings.
