An Improved Burner for Cooking Stoves and Soldering Apparatus.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings in the County of Middlesex, 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 cooking stoves of the kind which are composed of a
vessel and a system of tubes connected therewith (usually bent above into a coil)
into which petroleum or the like contained in the vessel can be forced up by means
of a pump or other device, from which pipes it comes forth in the form of gas
through a small hole in the burner placed at the upper part of the system of tubes,
the burner thus being heated by the flame formed by the ignition of the gas
encircling the greater part of the burner.
It is almost impossible however to clear such burners owing to the carbon
depositing itself in great quantities in the interior, they are also entirely useless if
the cleaning wire, when introduced into the fine outlet-hole of the burner, breaks
off and part remains in the said hole.
My invention which has for its object to remove these inconveniences is illustrated
in the accompanying drawing in which
Figures 1 and 2 show side views of my improved burner.
Figure 3 is a plan view of the same.
Figure 4 is a horizontal section on the line a-b of Figure 2.
Figure 5 is a vertical section on the line c-d of Figure 2 and
Figure 6 is a plan of a slightly modified form.
This burner consists of a plate 1, the interior of which contains two passages 2, 3
crossing each other, the passage 2 at each of its ends communicates with the upper
ends of two tubes 4, which open below into a short tube 5 intended to be screwed
upon another tube rising directly from the petroleum vessel. The ends of the
passage 3 are also connected with the ends of a bent tube 6, the lower part of
which lies above the joining point of the two tubes 4. On the upper side of this
tube 6 and under the middle of the plate 1 is arranged the outlet-opening for the
gas. This opening does not as usual consist merely of an opening in the pipe but
consists of a small burner proper 7 screwed into a socket on the pipe the interior
of the said burner communicates below through a small opening with the pipe and
is provided above with a small hole, through which the petroleum converted into
gas escapes. After ignition the gas encircles and heats the plate 1 with the
petroleum, which has passed through the tube 4, this petroleum being thus con-
verted into gas which passes through the tube 6 to the outlet opening of the
burner.
The decomposition of the petroleum and the deposition of carbon resulting
therefrom takes place in the tubes 4, which can be cleaned by screwing off the
burner, the interior of the tubes 4 being thus accessible for cleaning through the
short tube 5.
In the tube 6 on the other hand no deposition of carbon takes place. If the
the cleaning-wire should break and should remain sticking in the mouth-piece 7.
the latter can be unscrewed and the remaining part of the wire can be taken out,
without it being necessary to destroy the burner.
8 is a cap surrounding the burner and 9 is a small plate for the alcohol, which it
is necessary to use for the heating of the burner before ignition.

page_text: The plate 1 can also, as shown in Figure 6, be replaced by a cross-shaped piece
containing the two passages 2, 3, in which case the burner is particularly well
suited for soldering-apparatus as the flame from such an apparatus is better able
to reach the place to be soldered than the flame from the apparatus, shown in
Figures 1-5, the flame from this latter apparatus being spread aside by the
circular plate 1. The cross shaped piece in Figure 6 permits the flame to receive
a more concentrated form. It will be understood that more than two passages 2, 3
crossing each other in the burner, can be used, in which case some of these
passages are connected with the tube 5 and the others with the outlet opening for
the gas.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. In cooking stoves and soldering apparatus, in which petroleum or the like is
converted into gas in a series of tubes, a burner consisting of an upper part (1)
containing two or more passages 2, 3 crossing each other, tubes (4) passing
between the ends of one or more of these passages and a tube (5) lying under the
upper part, above mentioned and of one or more tubes (6) passing likewise under
the upper part between the ends of the other passage or passages, and substantially
under the middle of the upper part provided with an outlet opening directed
upwards.
2. In combination with the burner above described the removable burner
proper (7), inserted in the outlet opening of the pipe.
