FIGA UON
An Acetylene Generator for Use on Cycles, Carriages; or other
Vehicles.
We ALEXANDER JAMES SMITH Merchant, 11
Gladstone Place and
ALEXANDER GEORGE SMITH Optician 22 Gladstone Place, both of Aberdeen.
do hereby declare the nature of this invention to be as follows:-
The generator consists of an outer tube with a slip-on lid to which is attached
an inner tube of less diameter. In the inner tube is fixed a container for the
calcium-carbide. The container is a perforated tube held up the inner tube by
means of a wire which has a bayonet or other fixing at the bottom of the inner
tube or may be discs fixed at a certain distance apart on the wire. A stop-cock is
fixed to the lid of the outer tube having communication with the inner.

COMPLETE SPECIFICATION.
An. Acetylene. Generator for Use on Cycles, Carriages, or other
Vehicles.
We, ALEXANDER JAMES SMITH Merchant 11 Gladstone Place and
ALEXANDER GEORGE SMITH 22 Gladstone Place, Optician both of Aberdeen
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 a method of generating and controlling the generation
of the gas known as acetylene & an apparatus suitable for carrying on cycles,
carriages or other vehicles to supply the head light or side lights with acetylene.
The generator consists of a cylinder closed at the bottom and provided with an
air tight cover or lid at the top, except for a very minute hole drilled through the
cover or lid.
Inside this cylinder is another one open at the bottom & attached to the
cover by means of a pipe at the end of which is a stop-cock also attached to both
the cover & pipe.
The container for the calcium carbide consists of a disc or discs, fixed on a wire
or wires of suitable thickness & the discs made to fit the cylinder; or alternatively
may
be a perforated tube, held up in its position by a wire, either of which
container is held up in this cylinder by means of a bayonet-fixing at the bottom,
or connected by the wire to a screw on bottom through which is drilled a small
hole so as to allow the water to pass in & out of this cylinder, or such like
fixing.

page_text: We will now describe our invention with reference to the accompanying
drawing.
A is the outer cylinder.
B is the cover.
C is the inner cylinder.
D is the stop-cock.
E is the pipe connecting C with D.
F is the holder for the calcium carbide.
G is the fastening to hold F in position.
H is the small air hole.
To charge the generator C is removed and F is withdrawn from C. Calcium
carbide is put into F which is then replaced. A is about half filled up with water.
C is replaced & the cover B put on tightly. The stop-cock D is connected to
the burner by suitable tubing, and on opening the stop-cock air is expelled from C
by the weight of the water; which rises in C until it reaches the calcium carbide
in F when acetylene is given off; pressing down the water so that the generation
ceases until the gas is used & the water again rises to the calcium carbide to
make more acetylene.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1st. The use of acetylene gas in the lamps on cycles carriages or other
vehicles.
2nd. A generator which when subjected to vehicular motion will maintain a
pressure by means of the head of water & the air cushion supplied by means of
the hole H through the cover B.
3rd. In a generator the means of holding the container F inside C by a fastening
at the foot of C as herein described.
