Improvements in Acetylene Generators for Lamps for Fortable Use.
1, THOMAS LYOxs, of No. 1, Nightingale Street, Blackburn, in the County of
Lancaster, Sheet-metal Worker, do hereby declare the nature of this invention to
be as follows:-
:-
This invention consists of an improved generator for acetylene lamps for port-
able use being of simple and inexpensive construction and operates in such manner
that when water is allowed to drop on the calcium carbide the residue or slacked
lime falls to the bottom chamber of the generator and is thus seperated from the
dry carbide.
The generator according to this invention comprises a tube screwed at both ends
and has a smaller tube fixed through the side slanting downwards having on the
bottom end a wire cage affixed which contains the calcium carbide and at the top
end a cap is screwed on having a spiral spring screwed thereto which fits in the
tube and forces the calcium carbide into the cage.
At the bottom end of the larger tube is screwed a receptacle tapering outwards
to the bottom in which the residue is allowed to fall. At the top end of the said
tube is screwed an enclosed vessel or bulb made to contain water having a tap
fixed on the bottom of the said vessel with a small tube which carries the water
to the carbide in the wire cage.
The tap is constructed with a long plug so that the water may be regulated from
the outside after the whole apparatus is screwed up and made gastight.
As the water drops on the carbide the gas given off rises to the top portion of
the generator and is conveyed through a gaspipe to the bottom and enters a
stuffing box on the outside of the larger tube and is seived before passing on to
the burner.

Improvements in Acetylene Generators for Lamps for Portable Use.
I, THOMAS LYONS, of 1, Nightingale Street, Blackburn, in the County of Lan-
caster, Sheet Metal Worker, 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 improvements in acetylene generators and more parti-
cularly to those of a portable character, the object being to provide a simple and

page_text: inexpensive lamp that will be more effective and less liable to derangement than
many of the portable lamps at present in use.
My invention consists essentially in the provision of a chamber separate from
the gas generating chamber, in which the residue or slacked lime may fall; a
chamber for containing the carbide so arranged with reference to the gas generat-
ing chamber that the residue or slacked lime may be caused to fall into the
chamber just referred to and means for constantly pressing forward the carbide
to the line of flow of the water from the water chamber.
The invention will be fully described with reference to the accompanying draw-
ing which shows a vertical section of lamp containing all my improvements. In
this a is the gas generating chamber preferably circular in cross section though it
may have any other suitable shape. It is screwed at both ends and may be
screwed into or onto a chamber b containing water and a chamber e in which the
residue of the carbide of calcium or slacked lime may fall. The chamber a is pro-
vided at the bottom end with a conical plug or other valve d, the stem e of which
passes up through the top of the water chamber where it terminates in a handle,
lever or the like f, serving to lift the valve and so enable water to pass to the
generating chamber a. The valve stem'e may be screwed or the lever f may
work against a cam or inclined face on the water chamber so that on turning the
lever the valve is raised. g is a plug on removal of which the chamber may
be filled with water. This plug may be made in the form of a relief valve.
The chamber is open internally to the gas generating chamber, and is so
situated that the slacked lime readily falls into it.
is the chamber to hold the carbide of calcium and as will be seen is inclined to
the gas generating chamber at such an angle that the carbide always tends to
fall towards the generating chamber. It is firmly secured to the latter and at
its outer end is fitted with a removable screwed cap whilst its open end is covered
with a wire bonnet or similar device the extreme portion of which comes under
the line of water drip from the valve of the water chamber so that as water
drops on the carbide and gas is generated the residue of the former drops away
into the chamber c, leaving the remainder of the carbide dry, and in proper con-
dition for effectual use even if some considerable time elapses between using the
lamp. Internally the carbide chamber is provided with a coiled spring, the
lower end of which is flattened out or attached to a plate whilst the upper end
bears against the cap to which it may be attached if desirable. The spring k
is always in compression so that the carbide is constantly pushed towards the
wire bonnet as it is consumed. m is a pipe open at the top end so that as gas
is generated it rises and passes down it to the bend, and thence through a sieve
to the burner.
A gas generator such as I have described is very simple in construction and can
therefore be cheaply made, it can be easily cleaned and charged with carbide which
is not decomposed after the water supply for generation is cut off so that it is
ready for effective action on turning on the water again. Another feature of
importance arising from the arrangement also is that the undecomposed carbide
never mixes with the residue.
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. In acetylene gas generators of the type referred to the use of a carbide con-
taining chamber opening into the gas generating chamber and provided with a
wire bonnet to keep the carbide charge separate from the residue therefrom and
from the water and so that the residue and the carbide can descend to a residue
receiving chamber substantially as and for the purposes described.
2. In acetylene gas generators of the type referred to the use of a residue
receiving chamber distinct from the carbide containing chamber substantially as
and for the purpose described.

page_text: 3. A carbide containing chamber for acetylene generators of the type referred
to embracing in combination a body closed at its outer end by a removable cap i,
at its inner end by a wire bonnet and a spring k and plate 1.
4. In an acetylene generator the combination of a water chamber, a gas gene-
rating chamber, a carbide containing chamber and a residue receiving chamber
each separate from the others but all in communication as hereinbefore described.
5. The general arrangement, construction, and combination of parts forming
my improved acetylene gas generator substantially as described with reference to
the accompanying drawings.
