Improvements in Gas Stoves.
I, CHARLES CARR WILSON of the firm of Charles Wilson & Sons of Carlton
Street Leeds in the County of York, Gas Engineer, 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:
My invention has firstly for its object to arrange the gill-shaped flues of gas stoves
that carry off the combustion gases to the chimney to project forward from the face
of the stove before passing back to the chimney outlet, in order to bring the heating
surfaces thereof against which the air from the room passes well forward into the
room so as to increase the heating power of the stove, and secondly to construct the
Bunsens burner in such a manner that, for the purpose of reducing the heat, the outer
jets of the burner can be entirely turned off, while the inner ones remain more or less
full on, instead of regulating by turning the whole of the jets lower, whereby the
possibility of the flame flashing back to the gas inlet nozzle when the jets are
turned down very low is avoided.
For these purposes I construct the stove as I will proceed to describe with
reference to the accompanying drawing in which Fig. 1 shews a front elevation of a
gas stove with my improvements applied thereto, Fig. 2 shews a plan, Fig. 3 shews a
vertical cross section, Fig. 4 shews a sectional plan on line XX, and Figs. 5 to 7
shew enlarged details of the Bunsens burner.
The beating arrangement of the gas stove A may be of any known constructionbut
by preference I employ the arrangement described in the Specification to my Patent
No. 5209 of 1884. Instead however of providing the same with gill-shaped flues
leading up directly from the top of the stove, I close the top over as shewn, and fix or
form in front of the upper part a casting constituting a number of gill shaped
flues B B that project beyond the face of the stove and after rising a certain distance,
curve over the top of the same to the back, where they unite in a common chamber C
that communicates with the chimney through an opening D. The flues BB
consequently afford heating surfaces that project beyond the face of the stove, against
which surfaces the air circulating round the back of the stove passes on its way into
IDC1

point well forward into the room.
Fig. 5 shews an underside view of the Bunsens burner, Fig. 6 shews a section on
line YY and Fig. 7 a section on line Z Z. The gas pipe is provided with two
branches, one having a nozzle entering a tube E, and the other, which is provided
with a stop cock F. having a double nozzle entering each end of the curved tube G.
This tube has partitions at GG, so that the gas and air entering its open ends
only passes to the two outer nozzles.
The
The part of G between the partitions communicates through an opening E' with
the tube E and consequently the gas and air entering this tube will pass only to the
two middle burners. Thus when it is desired to reduce the heat, the two outer jets
can be turned off by the cock F, while the two middle ones are left full on.
gas pipe is provided with a stop cock H, by which the whole of the jets can be turned
off or regulated in the usual manner. It will be evident that this arrangement may
be applied to Bunsens burners with any other number of jets, and in combination
with other constructions of gas stoves.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Constructing gas stoves with gill-shaped flues B B extending forward from the
front of the stove and then curving backward to the chimney fluc, substantially as
herein described.
2. Constructing Bunsens burners to gas stoves with two tubes E and G supplied
with gas from separate nozzles, the tube E communicating with the middle gas jet or
jets while the tube & communicates with the outer jets so that the gas supply can be
turned off from the outer jets independently of that for the inner ones, substantially
as herein described.
