Improvements in the Construction of Acetylene Generators for
Portable Lamps.
I, JOHN GEORGE AULSEBROOK KITCHEN, of 44, Albert Road, Alexandra Park,
Manchester, in the County of Lancaster, Mechanician, do hereby declare the
nature of this invention to be as follows:-
:-
This invention has reference to generators for producing acetylene from calcium
carbide and a suitable reactionary liquid such as water, and consists in improve-
ments having for their chief object to obtain a simpler, less expensive and more
efficient apparatus than has hitherto been supplied.
My improved generator consists of a closed vessel of any suitable shape, one
side, preferably the bottom, of which is internally formed to receive a pad of
absorbent material such as wadding or felt, the opposite side, or top, is formed
with a neck which is externally, or internally, screwed to receive a collar capable
of adjustment along the axis of the neck. The collar encircles a long chamber
preferably made of metal tubing which chamber is provided at one end with a cap
and a tap and pipe or burner for taking off the gas, and is formed at the other end
with a comparatively small orifice and rim-facing.
Accord-
The larger vessel is charged with water through the neck or through a separate
charging hole. The carbide is placed in the long chamber which is passed into
the larger vessel through the neck and screwed down by means of the screwed
collar and screwed neck until its rim facing or its bottom comes in contact with
and presses upon the pad of absorbent material hereinbefore referred to.
ingly as the pad is more or less compressed, more or less moisture comes into con-
tact with the carbide through the small orifice in the rim facing of the carbide
chamber. In come cases a washer or packing of elastic material such as india-
rubber is placed round the pad so that the rim facing shall bear upon it.
The carbide in some cases is enclosed in a cage of wire gauze which cage is
inserted into the carbide chamber and thereby the carbide chamber is more readily.

I, JOHN GEORGE AULSEBROOK KITCHEN, of 44, Albert Road, Alexandra Park,
Manchester, in the County of Lancaster, Mechanician, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
This invention has reference to generators for producing acetylene from calcium
carbide and a suitable reactionary liquid such as water, and consists in improve-
ments having for their chief object to obtain a simpler, less expensive, and more
efficient apparatus than has hitherto been supplied.
In order that my invention may be more readily understood I have attached
hereunto a sheet of drawings to which I will now refer. In the said drawings,
Figure 1 represents a sectional elevation of my improved apparatus, and Figure 2
a cross section through line, x.
Referring now to the drawings:-My improved generator consists of a closed
vessel a of any suitable shape, one side, preferably the bottom of which is internally
formed to receive a pad of absorbent material such as wadding or felt; the
opposite side, or top, al is formed with a neck a² which is preferably, externally
screwed to receive a collar a³ capable of adjustment along the axis of the neck.
The collar encircles a long chamber c preferably made of metal tubing which
chamber is provided at one end with a cap cand a tap and pipe or burner
for taking off the gas, and is formed at the other end with a comparatively small
orifice and rim-facing c, which however may be omitted in some cases.
The larger vessel a is charged with water o through the neck a³ or through a
separate charging-hole not shewn in this drawing. The carbide p is disposed in
the long chamber c, which chamber is passed into the larger vessel a through the
neck a and screwed down by means of the screwed collar a³ and screwed neck
until its rim-facing or its bottom comes in contact with or presses upon the
pad 6 of absorbent material herein before referred to. Accordingly as the pad is
more or less compressed, more or less moisture percolates through the pad from its
circumference to the small orifice within the rim-facing of the carbide chamber.
In some cases a washer or packing of elastic material such as indiarubber is placed
round the pad so that the rim-facing shall bear upon it.
The carbide p is in some cases enclosed in a cage of wire-gauze not shewn in
the drawings which cage is inserted into the carbide chamber and thereby the
carbide chamber is more readily cleaned and recharged.
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 improved construction of generator for producing acetylene from calcium
carbide and water substantially as hereinbefore described and illustrated with
reference to the several figures of the drawings.
(2.) In generators for producing acetylene from calcium carbide and water the
use of a porous compressible material such as felt so disposed that the water must
percolate through said material from its circumference towards its centre in order

page_text: to flow to the carbide, and means for compressing said material to regulate the
percolation substantially as herein before described and illustrated with reference
to the several figures of the drawings.
