Improvements in Apparatus Employed in the Manufacture of
Acetylene Gas.
I, ODDUR VIGFUS SIGURDSSON, of 80, Shaftesbury Road, Ravenscourt Park,
Hammersmith, in the County of Middlesex, Engineer, do hereby declare the
nature of this invention to be as follows;-
The invention has for its object improvements in apparatus employed in the
manufacture of acetylene gas with a view firstly to the delivery by a simple valve
of the calcium carbide to the gas generating chamber as required to maintain the
supply of gas and secondly to facilitate the cleansing of the gas generating
chamber whilst the latter is in use.
In carrying my invention into effect I place the calcium carbide in powder or
in other convenient form in a hopper or supply chamber at the bottom of which
I arrange a feeding chamber having an opening communicating with the hopper
or supply chamber and another communicating with the gas generating chamber
and I provide such feeding chamber with a valve of such construction as to be
capable of communication with the calcium carbide supply chamber and with the
gas generating chamber, the apertures in the valve being so arranged that when
the bell of the gasometer or gas generating chamber rises a short distance and.
opens the valve only slightly the valve shall also be in communication with the
supply hopper so that carbide calcium cannot be supplied to the gas generating
chamber without at the same time admitting carbide to the valve from the supply
hopper.
The valve may be operated by a forked arm fixed on its spindle, such arm being
moved by the rise and fall of the gasometer bell by means of a pin or stud
carried by the body of the gasometer and entering the fork of said valve arm.
In order to enable the gas generating chamber to be cleaned out during the
working of the apparatus I provide the lower end of the gas generating chamber
with a conical bottom terminated by a discharge cock or valve and I connect to
the gasometer or gas generating chamber an Ŭ shaped tube one leg of which is
outside the apparatus whilst the other rises within the gas generating chamber
to the height required for the water level, the outer leg being above such level
and provided with means to connect it with a supply of water by a hose or other-
wise.
Thus by opening the discharge cock or valve and at the same time supplying
the apparatus with water the refuse in the gas generating chamber can be readily
cleared out.

I, ODDUR VIGFUS SIGURDSSON, of 80, Shaftesbury Road, Ravenscourt Park,
Hammersmith, in the County of Middlesex, Engineer, 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:-
The invention has for its object improvements in apparatus employed in the
manufacture of acetylene gas with a view to the delivery by a simple valve of
the calcium carbide to the gas generating chamber as required to maintain the
supply of gas.
My invention is illustrated in the accompanying drawings, in which:-
Fig. 1 is an elevation, Fig. 2 a vertical section and Fig. 3 a plan, of acety-
lene gas producing apparatus provided with my improvements.
it
Fig. 4 is a plan and Fig. 5 an end view of the valve and its operating lever.
Fig. 6 is a cross section and Fig. 7 a longitudinal section of the valve, showing
open to the supply chamber and closed to the gas generating chamber.
Figs. 8 and 9 are similar views of the valve showing it closed to the supply
chamber and open to the gas generating chamber, and
Fig. 10 is a plan and Fig. 11 an elevation showing a modified construction.
In all the figures like parts are indicated by similar letters of reference.
In carrying my invention into effect I place the calcium carbide, in powder or
in other convenient form, in a hopper or supply chamber a through a feeding
cock a', which is kept constantly closed except when the hopper is being supplied
with carbide. At the bottom of the hopper or supply chamber a I arrange a
feeding chamber 6 having an opening 6 communicating with the hopper and
another 2 communicating with the gas generating chamber d, and I provide such
feeding chamber 6 with a valve c of such construction as to be capable of com
munication with the calcium carbide supply chamber or hopper a and with the
gas generating chamber d, the apertures c¹ c2 in the valve being so arranged that
when the belle of the gasometer or gas generating chamber rises a short distance
and opens the valve only slightly, the valve c shall also be in communication with
the supply hopper a, so that carbide of calcium cannot be supplied to the gas
generating chamber without at the same time admitting carbide to the valve
from the supply hopper a.
The valve c may be operated by a forked arm c* fixed on its spindle c³, such.
arm being moved by the rise and fall of the gasometer belle by means of a pin
or stud d' carried by a rod d² fixed to the body of the gasometer, such stud
entering the fork of the arm c¹.
In order to enable the gas generating chamber to be cleaned out during the
working of the apparatus, I provide the lower end of the gas generating chamber
with a conical bottom terminated by a discharge cock or valve d, and I
connect to the gasometer or gas generating chamber d, an U shaped tube ff,
one leg f of which is outside the apparatus, whilst the other f¹ rises within the
gas.generating. chamber d, the outer leg f being above the water level and pro-
vided with means to connect it with a supply of water by a hose or otherwise.
Thus, by opening the discharge cock or valve d, and at the same time supplying
the apparatus with water, the refuse in the gas generating chamber can be readily
cleared out. ¹ is a gas supply cock, through which gas from the upper part of
the gas generating chamber d can be drawn off through a pipe g.
In the modification shown at Figs. 10 and 11 the gasometer e* is separate from

page_text: the gas generating chamber d and receives the gas from the latter through a
pipe h, whilst the supply hopper a is a fixture on the top of the gas generating
chamber d. Thus the pin or stud d', being carried by one of the slides el fixed
to the head of the gasometer e*, rises and falls therewith, and in such action
gives motion through the forked arm to the valve c. The gasometer shown at
Figs. 10 and 11 is for convenience of bellows form.
.
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:-
In acetylene gas producing apparatus, the combination with the gas generating
chamber, of a calcium carbide supply chamber or hopper fixed to the head
thereof, a feeding chamber at the base of the hopper communicating with the
latter and with the gas generating chamber, a valve within such feeding cham-
ber so formed as when slightly open to the gas generating chamber, it shall also
be open to the calcium carbide supply hopper, such valve being operated by
forked lever on its spindle and a stud carried by the gasometer, substantially as
herein set forth.
