COMPLETE SPECIFICATION.
An Improved Generator for Acetylene Gas.
We, JAMES ST. CLAIR LEGGE, Artist, and ARTHUR SISSON COOPER, Gentleman,
both of 168, North Strand, Dublin, 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 generator for use in generating acetylene gas, and
its object is to provide an arrangement of this kind which will allow the carbide
and water to be carried in the generator without coming in contact with each
other excepting when required.
In carrying out this invention we employ a casing or cylinder adapted to contain
a carbide holder and water tank. The holder for the carbide is placed within this
cylinder at one end, and space is left around the holder which is continuous with
the water tank so that a water jacket is formed completely enclosing the carbide.
A safety valve leads from the holder through the casing, so that if there is any
undue pressure of gas it can escape to the atmosphere. A pipe for leading off
the gas leads from the top of the holder through the water chamber passing out at
the end of the cylinder.
To allow the water to penetrate to the carbide, a perforated tube is employed
projecting within the holder and opening at its outer end to the water jacket.
This perforated tube preferably extends through the length of the holder so that
the water is supplied through the whole length." The water is sup-
plied and cut
off by
means
of
a'
the
small cock,
stem of which
extends through the holder and outer casing allowing the water to be turned on
and off from the outside.
The casing or outer cylinder can be provided with a partition or division which
forms two chambers. In one of these chambers the holder is fitted, and to supply
the water jacket with water small pipes are provided leading from the second
chamber which forms the water tank.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawings, in which Fig. 1 is a section of our improved apparatus,
and Fig. 2 shows a slightly modified form also in section.
Referring to Fig. 1 A is the external casing which may be of cylindrical or other
shape. Wtihin this casing the carbide holder B is fitted leaving a water space
or jacket a around the sides. The upper part of the casing serves as a water
tank. Projecting into the holder is the perforated tube C which extends through-
out its complete length. This is provided with the cock c at its upper end or at
the end opening into the water tank. As shown this cock can be operated from
the outside. D is the safety valve, the pipe projecting through the end of the
casing and extending through the tank. The tube E serves to take off the gas
which is generated inside the carbide holder.
The arrangement as shown in Fig. 2 is precisely similar, but the casing is
provided with the partition F dividing it into two compartments, one of which
receives the carbide holder, the other forming the water tank. The small tubes f
serve to supply the water jacket from the tank.
