COMPLETE SPECIFICATION.
Improved Means of and Apparatus for Producing Gas for Lighting
and other Purposes.
We, WILLIAM WATSON, of 200, Lytham Road, Blackpool, Plumber, and CHARLES
CHADWELL, of Richmond Chambers, Blackburn, Civil Engineer, both in the
County of Lancaster, 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 : —
This invention relates to the production of gas for lighting or other purposes,
and consists principally in the combination with the gas or vapor arising from
benzoline, or from gasoline of air or other suitable gas under pressure and in
mechanism for the above purpose.
The manner in which our invention is to be performed or carried into practical
effect will be readily understood on reference to the drawing-hereunto annexed
and the following explanation thereof.
The drawing represents in vertical section the working parts of a simple form
of lamp for producing and burning our improved gas. a is a vessel of suitable size
and form for containing the benzoline or gasoline which is to be fitted with suit-
able arrangements for charging and discharging the same. Fitted in the top of
the vessel a is a bent tube b which projects above the same and is provided with
a tap at c. The upper end of this tube is open and serves as a burner for the gas
which requires no wick. The lower part of the tube is carried down nearly to the
bottom of the vessel a and is then doubled or bent upwards its end opening into
the upper part of the vessel a above the level of the benzoline or gasoline.
A second pipe d is carried through the bottom of the vessel a and terminates
in an open mouth also above the level of the benzoline or gasoline. This pipe
is also provided with a tap e. At its lower end is a fan box f in which is mounted
a small fan g upon a horizontal spindle. The fan box is in communication with
a supply of air, or suitable gas under pressure, and when the fan g is set in action
it forces a supply of gas or air through the pipe d into the upper part of the
vessel a where it mingles with the gas or vapor arising from the benzoline or
gasoline and this admixture of air, or gas under pressure, will be found to greatly
intensify the light obtained by the burning of the benzoline or gasoline gas.
The revolution of the fan g may be obtained from a train of clockwork h fitted in
the base of the lamp when intended for household purposes or from any other
convenient source, and when used as a table or other portable lamp if it should
be accidentally upset the benzoline or gasoline would flow into the opening at
the top of the pipe d and thus shut off the supply of gas; and when the lamp is
designed to be used on a cycle or other carriage the motion of one of the wheels
of the vehicle may be utilized for driving the fan.
For large quantities of gas the apparatus will of course have to be made to a
much larger scale and instead of a single burner a long pipe can be applied
leading to several burners or to a suitable gasometer for storing the mixed gases
under pressure.

page_text: In some cases instead of a fan the requisite pressure can be obtained by allowing
a small quantity of sulphuric acid to drop upon zinc in a suitable vessel connected
to the said benzoline or gasoline reservoir or container.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved means of and apparatus for producing gas for lighting and other
purposes by mingling a current of air, or suitable gas under pressure, with the
gas or vapor arising from benzoline or gasoline, substantially as hereinbefore
described and illustrated by the drawing annexed.
