A New or Improved Portable Generator of Acetylene Gas.
We, GOTTHARD HANSEN, of 19, Oestergade, Copenhagen, in the Kingdom of
Denmark, Master Tailor, and AASMUND KRAFFTING, of 1, Kioebmagergade, Copen-
hagen, in the Kingdom of Denmark, Cigar Dealer, do hereby declare the nature
of this invention to be as follows:-
Most portable acetylene generators have the fault of burning irregularly as soon
as they are canted out of the vertical position, an important matter when such
generators are applied to cycle lights. This invention relates to a generator
specially fitted for use with cycles but applicable also in all cases where a portable
generator can be used.
The accompanying drawing diagrammatically illustrates, partly in elevation
and partly in vertical section, a generator constructed under our invention.
An outer vessel a provided with a series of holes near the bottom is threaded at
the top to receive a screwed lid b, this latter bearing a supply pipe with burner
and tap d.
Said outer vessel contains a shorter inner vessel e secured in position by means
of a collar. The lower part of this inner vessel is closed by a funnel-shaped perfor-
ated bottom f the centre of which is prolonged in the form of a short tube g within
which is pipe attached to and extending upwards from the water-tank h. The
latter is a short cylinder closed at all parts but having a tube j extending upwards
from its upper part and in which a wick is placed. Cylinder e is connected with
the water tank by a rubber cylinder 7 with airtight joints.
The action is as follows:
The water tank being filled with water through pipe j, the wick is placed in
position and then the water tank connected by the elastic cylinder 7 with cylinder e,
is placed in the outer vessel a, after which some carbide is laid on the bottom f
and the lid b is screwed on. The water from tank his soaked up by wick and
reaches the carbide in cylinder e, whereby acetylene is generated and the evolved
gas depresses the water tank as the rubber cylinder expands. This movement
removes the wick from the carbide whereby the evolution of gas is stopped at
once. As the pressure decreases the wick rises again to the carbide and a new
evolution of gas takes place, and so on.
As the carbide is decomposed the lime falls through the perforated bottom f
and collects on the top of the water tank h from which it can be easily removed
when cleaning the apparatus, for said bottom f merely rests upon the collar of
cylinder e, so that when lifted it can easily be washed free of lime.

We, GOTTHARD HANSEN, of 19, Oestergade, Copenhagen, in the Kingdom of
Denmark, Master Tailor, and AASMUND KRAEFTING, of 1, Kioebmagergade, Copen-
hagen, in the Kingdom of Denmark, Cigar Dealer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:--
Most portable acetylene generators have the fault of burning irregularly as soon
as they are canted out of the vertical position, a great drawback when such gener-
ators are applied to cycle lights. This invention relates to a generator specially
fitted for use with cycles but applicable also in all cases where a portable generator
can be used.
The drawing left with our Provisional Specification diagrammatically illustrates,
partly in elevation and partly in vertical section, a generator constructed under
our invention.
An outer vessel a provided with a series of holes near the bottom is threaded at
the top to receive a screwed lid b, this latter bearing a supply pipe c with burner
and tap d.
Said outer vessel contains a shorter inner vessel e secured in position by means
of a collar. The lower part of this inner vessel is closed by a funnel-shaped perfor-
ated bottom the centre of which is prolonged in the form of a short tube g within
which is a pipe j attached to and extending upwards from the water-tank h. The
latter is a short cylinder closed at all parts but having a tube j extending upwards
from its upper part and in which a wick k is placed. Cylinder e is connected with
the water tank by a rubber cylinder with airtight joints.
The action is as follows:-
The water tank being filled with water through pipe j, the wick is placed in
position and then the water tank connected by the elastic cylinder with cylinder e,
is placed in the outer vessel a, after which some carbide is laid on the bottom f
and the lid b is screwed on. The water from tank is soaked up by wick k and
reaches the carbide in cylinder e, whereby acetylene is generated and the evolved
gas depresses the water tank as the rubber cylinder expands. This movement
removes the wick from the carbide whereby the evolution of gas is stopped at
once. As the pressure decreases the wick rises again to the carbide and a new
evolution of gas takes place, and so on.
As the carbide is decomposed the lime falls through the perforated bottom f
and collects on the top of the water tank h from which it can be easily removed
when cleaning the apparatus for said bottom f merely rests upon the collar of
cylinder e, so that when lifted it can easily be washed free of lime.
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 a portable acetylene generator the combination of a carbide chamber, a
water tank, an air-tight elastic cylinder connecting said carbide chamber and said
water tank, and a wick extending from said water tank to said carbide chamber,
for the purpose of regulating the supply of water to the carbide under variations
of the pressure of the gas produced, substantially as set forth.
2. In a portable acetylene generator the combination of the parts mentioned
in Claim 1 with tubes such as g and substantially as and for the purpose set forth.

page_text: 3. The arrangement and combination of parts constituting the new or improved
portable generator of acetylene gas substantially as set forth with reference to
the drawing.
