FREDERICK SANSOM THORN, Gas Engineer, of No. 114 Vassall Road, North
Brixton, Surrey, and CHARLES HODDLE, Gas Engineer, of No. 84, Arthur Road,
North Brixton, Surrey, do hereby declare the nature of this invention to be as
follows:-
This invention has for reference to the use of acetylene for illuminating or other
purposes and provides a means whereby the gas is purified before ignition so
as to prevent the generation of smoke and fumes during the process of combustion.
To accomplish this we provide a vessel of cylindrical, or other, shape, fitted with
one or more moveable receptacles or trays containing chloride of lime, or other
purifying material, so arranged that when the apparatus is connected, by means of
a pipe, or otherwise, to any acetylene generator, or forms a part of any generator
the gas can pass over or through the purifying material before it is delivered to
the burner. We also provide in each receptacle or tray a moveable scraper or
stirrer capable of being actuated from the outside of the containing vessel while
it is in use, for the purpose of breaking up the surface of the purifying material
and bringing fresh portions into contact with the gas when required, in order to
efficiently maintain the purifying action. One or more of these vessels can be
used according to the quantity of gas to be dealt with and they can be connected
together in series when necessary.

COMPLETE SPECIFICATION.
A New or Improved Means and Apparatus for Purifying Acetylene.
We, FREDERICK SANSOM THORN, Gas Engineer, of 114, Vassall Road, North
Brixton, and CHARLES HODDLE, Gas Engineer, of 84, Arthur Road, North Brixton,
in the County of Surrey, 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 has reference to the use of acetylene for illuminating or other
purposes and provides a means whereby the gas is purified before ignition so
as to prevent the generation of smoke and fumes during the process of combustion.
To accomplish this we provide a vessel of cylindrical or other shape fitted with

purifying material so arranged that when the apparatus is connected by means of
a pipe or otherwise to any acetylene generator or forms a part of any generator

to the burner.
One or, more of these vessels can be used according to the quantity of gas to
be dealt with and they can be connected together in series when necessary.
In the accompanying drawings:
Fig. 1, is a longitudinal section of the apparatus.
Fig. 2, is a vertical section of the apparatus on the line 2, 2, of Fig. 1.
al, are cylindrical vessels or purifying chambers each closed at one end
and having at the other a circular cover b with joint ring and clamping screw of
ordinary construction.'
"
c, c, are connecting pieces for fixing together the cylindrical vessels a, a¹.
d, is a stand or foot forming part of the lower vessel a for the purpose of
supporting the apparatus when in use.
c, is the inlet pipe for unpurified gas.
f, is the outlet pipe for purified gas.
9: is a pipe open at both ends by means of which gas can flow from vessel a
to vessel a¹.
h, h, are horizontal moveable containers each open at the top in which the
chloride of lime or other material is placed.
The lower vessel a could be used alone or any number of cylindrical vessels
or purifying chambers such as a, or a¹ could be used in combination by suitably
arranging the inlet and outlet pipes.
The operation of the apparatus is as follows:
Chloride of lime or bleaching powder or combination of same with any other
material is placed in the containers h, h¹ which are then inserted into the
vessels a, aby means of the opening at the end of each vessel the openings being
then closed up gas tight by means of the covers and the parts in connection
therewith.
On the unpurified gas being admitted by means of the pipe e it passes through
that pipe and out at its open end into the vessel a then flows back over the surface
of the material in the container h, and out through the pipe g into the second
vessel, a in which it flows over the surface of the material in the second con-
tainer and finally passes out through the pipe f to which pipe any suitable
connection can be made for conveying the purified gas wherever required.
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. In any apparatus for the generation storage purification or combustion of
acetylene gas the use of chloride of lime or bleaching powder for the purpose of
purifying the gas.
2. The use of chloride of me or bleaching powder when combined with any
other material when such combination or mixture is used for purifying acetylene
gas.
3. An apparatus for containing material for the purpose of purifying acetylene
gas used and made substantially as herein described and shown on accompanying
drawings.
4. The combination and working together of any number of purifying chambers
as and for the purpose herein described and shown on accompanying drawings.
