CHARLES WEIGHTMAN HARRISON, of Mansion House Chambers, in the City of
London, Consulting Engineer "IMPROVEMENTS IN APPARATUS FOR CHARGING OR
IMPREGNATING ATMOSPHERIC AIR WITH INFLAMMABLE VAPOURS"
This Invention relates to improvements in apparatus for charging or impregnating
atmospheric air with inflammable vapours Such vapours are usually derived from
liquids containing volatile hydrocarbons, and the object of changing an with such
vapours is to produce inflammable gas or fluid adapted for lighting and heating
purposes.
My Invention relates, firstly, to a new form or construction of generator, this I
make of a shallow enclosed box of rectangular or other suitable form, and constructed
of copper, tin plate, or other suitable material Internally it is provided with
parallel vertical partitions joining the top and bottom plates, and alternately one or
other of the sides of the box. The generator is thus formed into a continuous
tortuous passage, the inlet for the an to which is at one end, and the outlet for the
hydrocarburetted air at the other, so that in passing through the air has to traverse
the whole of said passage This channel or passage is fiom end to end traveised by a
material more or less porous and absorbent, such as an open woolen or cotton fabric
placed in a zig-zag form, so as to compel the au in its passage through the generator
to pass through the pores of such absorbent and porous material The liquid to be
vaporised by the passing au is placed within the generator, and occupies the lower
part of same, re, of the continuous air passage, and thus the said absorbent material
1s saturated therewith by means of capillary or absorbent action The air to be
hydrocarburetted is forced or drawn through the generator, and so through the
saturated porous material, becoming thereby thoroughly charged or impregnated
with the vapour of the said liquid Raising and vaporising the liquid in this
manner the light vapours are not taken away first, as is the case with generators
previously in use, the light and comparatively heavy vapours being equally raised
and used
My Invention relates, secondly, to an improved form or construction of blower
for forcing the air through generators This I make of a collapsible vessel of

page_text: cylindrical or other form, the top and bottom of which are of wood, metal, or other
suitable rigid substance, and the sides of any suitable flexible air-tight material A
valve (or valves) is provided, opening inwards from the atmosphere when the ends
are diawn apart, by which means the vessel is filled with air, and on pressing the
ends together by a weight on the top the valve closes, and the air contained in the 5
vessel is forced through a second valve opening outwards through a pipe communi-
cating with the generator at a velocity proportionate to the pressure applied to the
collapsible vessel, which pressure may be adjusted to suit the number of burners to
be supplied with the inflammable gas or fluid
