JOHN LAWSON Hot Water Engineer Church Walk Bridlington East Yorkshire
do hereby declare the nature of this invention to be as follows:
My design is to Manufacture an Apparatus on a compound principle of air and
water, in a Furnace with a Coil of Tubing for water to heat the lower part of
Buildings around the Coil would be an Air Chamber separated from the fire by
brick work the Air to be heated by latent heat from the Furnace and carried in
Shafts Pipes, or Flues over the heads of the congregation or assembly, thereby.
avoiding the inhalation of sulphur from heated air-This arrangement would
specially apply to the Apex of high roofed buildings or lofty ceilings, where the cold
air descends on the audience.
COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Buildings by Combination
of Air and Water.
I, JOHN LAWSON Hot Water Engineer (late of Church Walk Bridlington) now
of Pembroke Terrace Bridlington Quay, East Yorkshire, 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 present invention has for its object the warming or heating of buildings so
that the upper and lower portions thereof are heated simultaneously, by which means
a more uniform atmosphere is maintained within the building, and sulphur or other
product from the combustion of Gas or other lights is expelled, and a better ventilation
is able to be secured throughout the building; to attain which I arrange a heating or
warming apparatus upon a compound principle which will be clearly understood by
reference to the accompanying drawing and noting the following description thereof:
Fig. 1. represents a cross sectional elevation of a building fitted with a heating
apparatus constructed according to my present invention.
A furnace A which is preferably of fire brick, has arranged over it an ordinary
boiler or water heater B composed of wrought iron or other suitable metal. Connected
to the said heater B is a coil of hydraulic tubing C through which the heated water
passes; and is arranged to circulate along the pipe C₁ for the purpose of heating or
warming the lower portion or space of the building or room M in the usual way.
Over or above the boiler or water heater B, or where preferred at either side
thereof, or arranged in any other manner so as to receive heat from the same fire
which heats the water in the boiler or heater B, is an air chamber D connected to
which is a tube or pipe E which preferably extends through the chimney or flue F
and then along the inside of roof to the apex where it communicates with a distributer
or pipe of a larger diameter H, which may be perforated only under each ventilator G, or
the whole of its length, which I prefer to be the full length of roof of building. It
will be obvious however that when desirable the pipe E may terminate at the apex of
the roof under the ventilator G or at any other position in or near the roof of the
room or building in which case the distributer H may be dispensed with. I do not
limit myself to the number of air pipes or tubes E, as any number may be arranged
and conducted to each ventilator, which may be situated at the apox or any other
part of the roof of room or building.

page_text: The rarefied or heated pure atmospheric air thus conveyed to the ceiling or roof of
building prevents all down draught and displaces all noxious or foul gases or breathed
air from the people occupying the room or building, thus improving the ventilation;
and by means of the upper part of. room being heated with pure air and simultaneously
the lower portion with heated water, an uniform temperature is maintained throughout
the room or building.
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 means for heating or warming buildings or rooms the combined use of air
and water arranged substantially as described and illustrated in the drawing annexed
or any mere modification thereof.
2. Arranging a furnace A used for the purpose specified so that it will heat water:
and air simultaneously.
$
3. The combined application of heated air and water in the manner set forth and for:
the purpose specified.
