I, THOMAS ROUS, of The Schools, Ardleigh, in the County of Essex, Gentleman,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in acetylene gas generators for illumi-
nating purposes and is especially applicable to lamps for use with cycles and other
vehicles. My improved, generator consists of a vessel or chamber of about six inches
in length by three inches in width and preferably of oval shape in cross section. This
vessel is divided by a partition into two parts one of which contains the carbide
holder consisting of a perforated.tubular chamber and the other contains water, the
two being connected together at the bottom by a pipe fitted with a water tap. The
carbide holder is closed at the top by a screw stopper or cap a similar stopper being
fitted to the water chamber for filling the latter and which is provided with a safety
valve for permitting the gas to escape slowly when the light is turned off a spring
safety valve being also fitted to the carbide chamber for preventing possibility of
explosions.
The said chamber is also provided with a gas tap at the top and a water outlet
tap at the bottom.
The generator may be clipped to the frame of a cycle underneath the saddle and
connected to the lamp in front by means of a tube or it may be fixed to the frame
near the crank axle bearing in which case it may be formed of a conical shape and
the carbide holder be carried centrally within the same.
By means of my invention fresh carbide, or water can be easily added when
required and the water can be drained off from the carbide by the lower tap when
the light is not in use, it can also be easily cleaned and there is no waste of carbide.
Dated this 12th day of February 1898.

Improvements in Acetylene Gas Generators for Lamps.
I, THOMAS ROUs, of The Schools, Ardleigh, in the County of Essex, Schoolmaster,
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 improvements in acetylene gas generators for illuminating
purposes, and is especially applicable to lamps for use with cycles and other vehicles,
also for use with optical magic lanterns and the like. My improved generator

page_text: G
consists of a vessel or chamber of about six inches in length by three inches in width
and preferably of oval shape in cross section.
This vessel contains another which is termed the carbide chamber which is fitted
at the bottom with a water tap, the inside end of which extends to the centre of the
carbide chamber, and is perforated with two holes directly opposite each other, the
said tap being worked and regulated by a lever or handle on the top of the generator,
the carbide chamber is closed at the top by a screw stopper or cap, a similar stopper
provided with a small air hole being fitted to the water chamber, for filling the
latter, the said hole also providing a means of escape for superfluous gas. The said
carbide chamber is also provided with a gas tap fixed on to the top of the screw
stopper, and the water chamber is fitted with an outlet at the bottom, directly opposite
the water tap connected with the carbide chamber.
The generator may be clipped to the frame of a cycle, underneath the saddle, or
carried in a bag strapped to the cycle frame, and connected to the lamp in front by
means of a tube, or it may be fixed to the frame near the crank axle, or near the head,
in which case it may be formed of a conical shape and the carbide holder be carried
centrally within the same. If used with a lantern the generator may be connected
with the burner in a similar manner.
By means of my invention fresh carbide or water can be easily added when
required, and the water can be turned off by the tap provided for the purpose,
when it is necessary to stop the further generation of gas. It can also be easily
cleaned.
The accompanying drawing a sectional elevation shews my improvements in
acetylene gas generators for lamps as fitted for generating acetylene gas as hereintofore
described.
A is a chamber for the reception of carbide by means of B, a screw stopper or cap,
fitted with a leather (or other like material) washer C. This chamber is
connected with the water chamber 1) by means of a tube G, the end of which
is in the centre of the carbide chamber A, and is perforated with two holes H, the
flow of water through this tube being regulated by the tap I. The water chamber is
fitted with a screw stopper E provided with an air bele F. The tap I is worked by a
handle or lever J, situated on the top of the generator. The water chamber D allows
the water to surround the carbide chamber A. K is a tube, provided with a tap L.,
forming the outlet for gas, the end M, of which, is connected with the burner of the
lamp by means of rubber (or other like material) tubing. N is an outlet to the water
chamber, and is fitted with a small screw plug. This outlet N being useful for oiling
the tap I when necessary, it also facilitates cleaning.
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
The arrangement and combination of parts constituting an acetylene gas
generator substantially as and for the purposes hereintofore described and shown.
