WILLIAM PHILLIPS THOMPSON Fel Inst P.A. of the Liverpool and London

"
This invention has for its object the utilization of gas for the heating of air to
be conducted to various portions of the building and consists in apparatus for this
purpose.
The invention is applicable not merely for supplying hot air diluted with the
products of combustion, but also for supplying such air at a high temperature to
heating tables or calorifères placed in the various rooms.
It is best described by aid of the accompanying drawings.
Fig 1. is a Sectional elevation of the apparatus.
Fig. 2. plan of Same, partly in Section
Fig. 3 Section of injector or tap for admission of air and gas for combustion.
Fig. 4 transverse Section of injector on line x-y.
In these a is the pipe for admitting the air to be heated, b tap or injector shewn
on enlarged scale Fig 3) c vertical gas pipes, d circular gas pipes connecting c
together, c' burners for the mixed gas and air, e diaphragms or baffle plates for
guiding the current of heated air, f tubes or pipes through which the heated air is
distributed or carried to its destination, g central heating chamber, h outside casing
of the apparatus.
The air to be heated passes from the outside of the building or structure through
the pipe a into the centre of the bottom of the apparatus, and from the pipe a it
passes through the heating chamber g. This chamber is provided at intervals in
its height with rings of burners c', at which points the mixture of gas and air from
the injectors b is ignited, and the air entering from the pipe a comes in contact
with the several tiers of burning gas and is heated thereby. The diaphragms or
baffle plates e placed against the sides of the chamber g are intended to keep the
air in the middle of the flame, and they gradually increase in size from the bottom
to the top, thus contracting the orifice at each time through which the air passes
as Shewn. These plates will of course vary in size, according to the size of the
apparatus. Thus the air cannot do otherwise than pass through the flames which
cross one another. The heated air then rises to the upper part entering the pipes f,
which may be made of Stone, iron, copper, or other Suitable material, and which
are designed for distributing the heated or warm air to the airholes or outlets,
which are placed in each of the rooms of a house, or of an hotel. In order to
obtain a better current of the warm air, a cock b¹ is placed at each of the pipes f,
where the air from the chamber g enters it, the mixture of gas and air from these
cocks is ignited; by this circumstance the air which passes from the inside of the
heating apparatus is warmed to a very high temperature.
It is by the use of cocks or injectors such as herein described which admit of a
passage of gas mixed with air sufficient to complete the combustion of the gas
introduced, that the heating of the air can be successfully accomplished and rooms
heated in this manner without any unpleasant smell
A sliding door is placed in the body of the apparatus in order to light the burners
inside with ease.

page_text: This apparatus may be ornamented with a covering of talc, enamelled iron, or
other Suitable material, and ornamented with Howers, fruits, portraits, et-cetera.
Having now described the invention as communicated to me, I wish it to be
understood that what I claim and desire to protect is.
1st The herein described apparatus for heating air for warming rooms or buildings,
in which the air passes through a chamber wherein it comes in contact with the
flame issuing from a Series of gas jets in which the gas is mixed with air Sufficient
for its combustion, substantially as described and Shewn.
2nd The use of a tap or injector for Supplying gas to a heating apparatus or burner
in which a nozzle from the gas supplying pipe leads into a chamber furnished with
a series of apertures through which the air enters and mixes with the gas substan-
tially as described and Shewn.
3rd. The general arrangement and construction of apparatus for heating air for
rooms or buildings substantially as described and Shewn.
In witness whereof I the Said William Phillips Thompson have hereunto Set my
hand and Seal this twenty eighth day of September in the year of our Lord one
thousand eight hundred and eighty three.
