Improvements in the Manufacture of Gas for Heating Purposes.
I, SAMUEL POINTON, late of 71, Exeter Street, Ardwick, now of 201, Plymouth
Grove, Manchester, Lancashire, Engineer, 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:-
The improvement which forms the subject of this invention consists in pro-
viding means for utilizing the exhaust steam of any steam engine, by the pro-
duction of water-gas therefrom with the object of assisting combustion in the
furnaces of said steam engines.
purpose of
my
invention.
In the accompanying drawing, Figs. 1 and 2 are longitudinal sections of
horizontal tubular boilers or cylinders, and Fig. 3 a longitudinal section of an
inclined tubular boiler such as may be employed for the
In these views similar letters refer to similar parts.
According to my invention I connect the exhaust steam pipe leading from the
cylinder of any steam engine to the lower part or one end of either a tubular
boiler or cylinder or an equivalent as at a in either of the figures shown on
the drawing. In Fig. 1 the steam passes through the space contained within
the cylinder that in boilers is usually filled with water and contains the tubes c
through which the flames and hot gases from the furnace d are caused to pass
to the chimney . The tubes are heated to a high temperature and the steam
in its passage from the inlet a between or around the tubes towards the outlet g
that is at the opposite and upper end of the cylinder is converted into water gas
of great purity. In Fig. 2 an inlet for the exhaust steam is provided near
each end of the bottom of the cylinder as at a and a² the outlet being placed
in or near the centre at the top of the cylinder. In Fig. 3 the exhaust steam
passes through the tubes and the flames and hot gases from the furnace are
carried over and under and around the tubes by deflectors or baffles as f to
the chimney flue e. The tubes are fitted in headers the steam entering at t
and the gas that is generated having an outlet as g at the upper and opposite
end of the nest of tubes c.
In applying my invention the tubes are heated to redness and the exhaust
steam is caused to enter the cylinder or boiler near the fire box or furnace,
where the heat is greatest, passing around or through the tubes, gas being
thereby produced which is conveyed by a pipe or pipes attached to the upper
part of a tubular boiler or cylinder to a gas holder, the outlet for the gas being
fixed at the opposite end to that at which the steam enters the boiler or cylinder,
the gas thus obtained is intended to go direct into consumption, the gas holder
not being required for storage purposes but only to facilitate distribution to
lifferent points where the gas is utilized as soon as produced, the tubes may be
either Muntz's metal, copper, aluminium or other prepared material.
I do not confine myself to the precise form or construction of tubular boilers
or cylinders shown on the drawings as these are only for the purpose of illustra

invention.
Having now particularly described and ascertained the nature of my said
invention. and in what manner the same is to be performed I declare that what
I claim is:
1. The production of water gas from the exhaust steam of any steam engine
by the combination with said steam engine of a cylinder or an equivalent con-
taining tubes through which flames or hot gases pass from the furnace at one
end to the chimney at the opposite end of said cylinder and the exhaust steam
circulating, over, under and around said tubes in its passage from an inlet
near the furnace to an outlet near the chimney substantially as and for the
purpose hereinbefore described.
2: The production of water gas from the exhaust steam of any steam engine
by the combination with said steam engine of an enclosed nest of tubes through
which said exhaust steam passes from an inlet near the furnace to an outlet near
the chimney, the flames and hot gases circulating under, over, and around said
tubes substantially as and for the purposes herein before described.
