Improvements in or relating to Burners for Acetylene Gas.
We, OSCAR FALBE and EMIL BORCHARDT, both of 77, Manteuffelstrasse, Berlin,
in the Empire of Germany, Manufacturers, do hereby declare the nature of this
invention to be as follows:
As is well known the burner passage or opening in acetylene gas burners is
extremely narrow. The consequence of this is that the burner becomes very rapidly
choked or stopped up with the deposit of the residues of combustion, and thus
renders it very difficult to clean same owing to the fineness of the burner mouth.
In order to prevent any stopping or choking of the burner and to render possible
or facilitate the cleaning of the stopped burner, we cover the burner mouth with
a hood or cap and provide said hood or cap with a suitable but somewhat larger
opening than the burner mouth and thus a free passage to the emerging gas jet
is obtained and the flame only burns above the covering cap and does not directly
extend to the burner opening. The residues of combustion thus deposited cannot
stop or choke the narrow burner passage as any stoppage of the hole in the covering
cap or hood is almost entirely prevented owing to said hole being considerably
larger than the burner opening. If however the passage in the cap should become
choked it can be very easily cleaned as it is of sufficient width to allow of this
being readily done. The covering hood or cap may of course be used equally well
for burners with one opening or with several openings.
One method of carrying out the invention is as follows:-
A two-hole burner is provided in which the two emerging gas jets encounter
one another at a suitable angle with the object of producing a broad flame, and a
covering cap or hood is loosely placed or fitted with slight friction on the burner.
The two ends of this cap are provided with openings which exactly cover the actual
burner openings and are made somewhat larger than the latter.
Another form of construction of a two hole burner consists in the covering cap
being firmly connected in any suitable position with the burner itself.
The form of the covering cap is immaterial and is of course preferably made to
suit that of the burner, the essential feature of the invention consisting in pro-
viding the actual burner opening with a cap having a larger opening.
The invention is also applicable for use with split burners.

We, OSCAR FALBE and EMIL BORCHARDT, both of 77, Manteuffelstrasse, Berlin,
in the Empire of Germany, Manufacturers, 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:-
As is well known the burner passage or opening in acetylene gas burners is
extremely narrow. The consequence of this is that the burner becomes very rapidly
choked or stopped up with the deposit of the residues of combustion, and thus
renders it very difficult to clean same owing to the fineness of the burner mouth.
In order to prevent any stopping or choking of the burner and to render possible
or facilitate the cleaning of the stopped burner, we cover the burner mouth with
a hood or cap and provide said hood or cap with a suitable but somewhat larger
opening than the burner mouth and thus à free passage to the emerging gas jet
is obtained and the flame only burns above the covering cap and does not directly
extend to the burner opening. The residues of combustion thus deposited cannot
stop or choke the narrow burner passage as any stoppage of the hole in the covering
cap or hood is almost entirely prevented owing to said hole being considerably
larger than the burner opening. If however the passage in the cap should become
choked it can be very easily cleaned as it is of sufficient width to allow of this
being readily done. The covering hood or cap may of course be used equally well
for burners with one opening or with several openings.
One method of carrying out the invention is shown in sectional elevation in
Figure 1 and in plan in Figure 3 in the accompanying drawings, and consists as
follows:-
A two-hole burner is provided in which the two emerging gas jets encounter
one another at a suitable angle with the object of producing a broad flame, and a
covering cap or hood e is loosely placed or fitted with slight friction on the burner.
The two ends of this cap are provided with openings d which exactly cover the
actual burner openings and are made somewhat larger than the latter.
Another form of construction is shown in sectional elevation in Figure 2 and
consists of a two orifice burner in which the covering cape is firmly connected in
any suitable position with the burner itself.
The form of the covering cap is immaterial and is of course preferably made to
suit that of the burner, the essential feature of the invention consisting in pro-
viding the actual burner opening with a cap having a larger opening.
The invention is also applicable for use with split burners.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. The improvement in or relating to acetylene gas burners, whether split or
orifice burners, which consists in covering the actual mouth of the burner with a
fixed or removable cap or hood having at a point corresponding to the burner
mouth a passage for allowing the current of gas to pass through with the object
of preventing any stoppage of the actual burner mouth, substantially as herein-
before set forth.
2. The combination with an acetylene gas burner, of a hood or cap constructed
and arranged substantially as described with reference to Figures 1 and 3 of the
accompanying drawings.
3. The combination with an acetylene gas burner, of a hood or cap constructed
