Improvements in and connected with Bunsen Burners for Gas Stoves,
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Franz Houben,
Proprietor of the Firm of J. G. Houben Sohn Carl, of 5 Edelstrasse 5, Aachen,
Rhine Provinces, Germany, Manufacturer, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to certain new and useful improvements in Bunsen
burners for gas stoves having gas-jet nozzles, which are arranged in a position
inclined to the axis of the mixing-tube.
Bunsen's well known gas burner requires a mixing tube the length of which
is in proportion to the consumption of gas, in order that the gas and air may
be thoroughly mixed on its way to the upper opening and a perfectly uniform and .
complete combustion be effected.
In a gas burner for the Bunsen form of bath room stove, which consumes about
4 cubic meters of gas or more per hour, the mixing tube must be of a considerable
length, say, about one meter for the above named consumption. This would
make the burner unnecessarily high, and a bathroom stove combined with the
ordinary heating stove, now frequently in use, would reach a considerable height,
which would render the handling of the gas cocks very difficult and the setting
up of such combination stoves impossible in bath rooms with low ceilings.
The purpose of this invention is to effect the mixture of gas and air in gas
burners for large consumption by using a comparatively short mixing-tube.
The invention is illustrated in the accompanying drawings wherein :-
Fig. 1 shows the arrangement in vertical section and Figs. 2 and 3 show
details of the same.
The mouthpiece a of the gaspipe which is surrounded by the air inlet f and
turned towards the mixing tube c is provided with the gas-jet-nozzles & the axes
of which are inclined towards the axis of the gasburner so that the conical gas-
jets issuing from the gaspipe r through these nozzles, at an acute angle, strike
the interior of the mixing-tube c-d and from there glance off at a corresponding
angle; the gas-jets thus crossing one another frequently, will mix thoroughly
with the air drawn in at f, thus producing a thoroughly effective mixture of gas
and air which will reach the gas burner holes e.
The mixing tube - with the openings e in the gas burner may be of any
desired shape, for instance composed of two cones as shown in Fig. 1, or of a
cone and a cylinder as in Fig. 2.
In order to check the rising of the gases around the exterior of the mixing-
tube c―d owing to unfavourable conditions of draught in the chimney or to other
causes, which gases reaching the flames of the gas burner would cause
ignition around the nozzles a plate has been provided which separates the
space sui rounding the air inlet f from the space around the mixing-tube c-d.

gas-jet-nozzles b.
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. A Bunsen burner for bath-room gas stoves having the mouthpiece a, which
is surrounded by the air inlet f and turned towards the mixing-tube -, pro-
vided with gas-jet-nozzles b, the axes of which are inclined towards the axis of
the gasburner so that the conical gas-jets issuing from these nozzles at an acute
angle, strike the interior of the mixing tube and from there glance off at a
corresponding angle; the gas-jets thus crossing one another frequently and mixing
thoroughly with the air drawn in at f, all substantially as described and illustrated.
2. In a Bunsen burner of the kind indicated in Claim 1 hereof, means for pre-
venting the gases from rising around the exterior of the mixing-tube -, con-
sisting of a partition in the shape of a plate y which separates the space surround-
ing the air-inlet f from the space around the mixing-tube c-d; all substantially
as illustrated and described for the purpose set forth.
