PROVISIONAL SPECIFICATION.
Improvements in or relating to Generators for Acetylene Gas.
We, HENRI DE THIERSANT, Clerk, and WILLIAM ALLEN COULSON, Freight
Manager, both of 97, Cannon Street, London, E.C., do hereby declare the nature
of this invention to be as follows:-
This invention consists of improvements in or relating to acetylene gas
generators, being particularly applicable to that class of generator which is
used upon velocipedes and the like.
In carrying out my invention I provide a cylinder which carries the carbide
through the medium of a cage or perforated holder. This cylinder is stamped,
shaped or pressed inwards so as to provide a groove or grooves, preferably spiral,
running around the cylinder aforesaid. These grooves are provided with per-
forations at suitable intervals. An outer jacket is provided into which the
cylinder aforesaid fits tightly, the whole being immersed when required in a
casing containing water. It will be seen that the water passes up the groove
aforesaid and comes into contact with the carbide through the apertures.
A suitable outlet is provided for the escape of the generated gas, which may
be conveyed to any suitable form of burner after having passed through
filtering material if desired.

Improvements in or relating to Generators for Acetylene Gas.
We, HENRI DE THIERSANT, Clerk, and WILLIAM ALLEN COULSON, Freight
Manager, both of 97, Cannon Street, London, E.C., do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention consists of improvements in or relating to acetylene gas
generators, being particularly applicable to that class of generator which is
used upon velocipedes and the like.
In carrying out our invention we provide a cylinder which carries the carbide
through the medium of a cage or perforated holder. This cylinder is stamped,
shaped or pressed inwards so as to provide a groove or grooves, preferably spiral,
running around the cylinder aforesaid. These grooves are provided with per-
forations at suitable intervals. An outer jacket is provided into which the
cylinder aforesaid fits tightly, the whole being immersed when required in a

page_text: casing containing water. It will be seen that the water passes up the groove
aforesaid and comes into contact with the carbide through the apertures.
A suitable outlet is provided for the escape of the generated gas, which may
be conveyed to any suitable form of burner after having passed through
the desired filtering material.
For purposes of illustration, we will now refer to the annexed drawings in
which:
Figure 1 is a sectional side elevation shewing our invention.
a is an outer casing for the purpose of containing water: b is a cylinder
which carries the carbide of calcium c through the medium of the cage or
perforated holder d. This cylinder is stamped shaped or pressed so as to
provide a groove or grooves e preferably spiral and running around the cylinder b
aforesaid. These grooves e are provided with apertures fat suitable intervals.
An outer jacket is provided into which the cylinder 6 aforesaid fits tightly,
being secured in position by means of pins h upon the cylinder b which engage in
suitable slots i formed in the outer jacket g. Of course any convenient means of secur-
ing the two parts in position may be employed. The gas generated passes through
the outlet to the required point of consumption, this form of apparatus is
particularly adapted for use as a bicycle lamp, as the water obtains access to
the carbide of calcium through the medium of the grooves e and apertures f
in the cylinder b. Any desired filtering material may be interposed between
the point of issue and the point of ignition of the gas for the purpose of
purifying the gas. Although we have described our invention as applied to
a cylindrical vessel, it will be readily understood that the shape of this vessel
may be varied and that of the surrounding outer jacket without departing from
our invention.
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:-
:-
1. The improved generator for acetylene gas, substantially as described and
illustrated herein and for the purpose set forth.
2. In generators for acetylene gas, a cylinder carrying the carbide of calcium
in a suitable casing or holder, said cylinder having grooves or indentations
pressed stamped or shaped upon said cylinder, apertures or perforations in said
grooves or indentations, an outer jacket or casing adapted to fit tightly upon
the cylinder carrying the carbide of calcium and holder, an outer casing in
which the jacket and cylinder aforesaid may be placed for the purpose of
enabling the water to come into contact through the medium of grooves and
perforations in the cylinder aforesaid of the carbide of calcium, an outlet for
the escape of the generated gas, substantially as described and illustrated herein
and for the purpose set forth.
3. In generators for acetylene gas, a cylinder in which the carbide of calcium
is carried, grooves or indentations having perforations or apertures upon said
cylinder in combination with an outer jacket adapted to fit tightly upon the
cylinder, substantially as described and illustrated herein and for the purpose
set forth.
