PROVISIONAL SPECIFICATION.
An improved Automatic Acetylene Gas Generator, Single or Double
Acting.
WILLIAM MARRS, 57, Griffin Road, Plumstead, Kent, Engineer, I do hereby
declare the nature of this invention to be as follows:
Consisting of an enclosed water cistern in which is fitted escape pipes for the
conveyance of gas to store chambers, in which gas is stored before being conveyed
through further pipes to purifier, which is attached to cistern and from which gas
is conveyed to burners.
Also an automatic generator inside enclosed cistern, if single acting one
generator, if double acting, two generators. In each generator is fitted a movable
basket containing carbide of calcium from which acetylene gas is procured when
it is brought into contact with water.

COMT DETE DIEUITICATION.
An Improved Automatic Acetylene Gas Generator, Single or Double
Acting.
WILLIAM MARRS, 57, Griffin Road, Plumstead, in the County of Kent, England,
Engineer, I 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 an improved acetylene gas generator: -Single or double
acting; and consists in the construction and arrangement thereof; the object of
the invention being to safely and automatically control the generation of the gas,
so that it passes from the apparatus for consumption at an uniform pressure.
The apparatus is shewn in the drawing by Fig. 1 in sectional elevation, and by
Fig. 2 in plan.
Å water cistern (a) with a removable lid (b) made gas tight by one or more
leather, indiarubber, or the like washers, and secured by means of a
clamp and
screw or the like means, contains an automatic generator (c) with a similar
removable gas tight lid.
The calcium carbide from which the acetylene gas is to be generated is contained
in a movable basket which fits in the generator. Holes (d) in the upper part of
the generator allow water from the water cistern to pass to the carbide when the
generator sinks low enough in the water to permit of this. Water is supplied to

page_text: the water cistern through a cup (e) at the normal water level: This cup is made
water tight by means of a screw down lid or the like and leather, indiarubber, or
the like washers. The gas from the generator passes by escape pipes (f, g) to a
store chamber (h), and from the store chamber, by a pipe (i), to a purifying
chamber (k), and thence to the burners. The purifying chamber preferably con-
tains soft-wood sawdust resting on a layer of cotton wool, and covered by a second
layer of cotton wool. Moisture carried over by the gas to the purifying chamber
collects in a chamber (1) with a drain cock (m). A safety valve (n) may be fitted
to the apparatus. In Fig. 1 of the drawing the generator is shewn charged with
calcium carbide, and kept high out of water by the air contained in it. If now
the burners are turned on, the air rushes out, the generator sinks until water passes
to the calcium carbide through the holes (d) and the generation of gas commences,
when the generator immediately rises and cuts off the further supply of water from
the carbide. When the consumption of gas causes the generator to fall water is
again admitted to the calcium carbide. Thus the generator alternately falls and
rises until acetylene gas ceases to be generated.
If the apparatus is to be double acting, the water cistern contains two automatic
generators which are connected to the pipe (2) by two branch pipes each provided
with a cut off cock, so that one or both of the automatic generators may be used.
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
1 The general arrangement of an apparatus for generating acetylene gas, single
or double acting, constructed and operated substantially as herein before described
and illustrated by the drawing.
2 In a single or double acting apparatus for generating acetylene gas, the
arrangement of the one or two automatic generators contained in a water cistern
with a store chamber, the cup for filling the water cistern, the purifying chamber
with its drain chamber and drain cock, the safety valve, and, in double acting
apparatus, the two cut off cocks.
