Improvements in Atmospheric Gas Burners.
We, MARC FERDINAND SOLON, of II Furlong Lane, Burslem, Potter, MARCUS
BIBBERO of Stock Street, Cheetham Hill, Manchester, Commercial Traveller, and
JOHN CUTHBERT BAILEY of Bradwell Lodge, Porthill, Burslem, Potter, do hereby
declare the nature of our said invention to be as follows:
"
Our invention relates to a new or improved construction of atmospheric or
"Bunsen gas Burner suitable for heating and boiling purposes and has for its
object the "regeneration" of the gaseous mixture previous to ignition, and our
invention consists in forming the Burner in the form of a 'muffle or chamber with
holes, slits, or other similar orifices through which the gaseous mixture issues and
burns around the muffle, and so heats such muffle to a high temperature, which in
turn acts as a regenerating surface for the oncoming mixture inside the muffle.
The orifices are at the lowest portion of the muffle and so arranged as to cause the
flame to partly or wholly envelope the muffle. The gas may be supplied to the
muffle. on the well known "Bunsen " system, care being taken that the mixture is
conveyed well into the muffle so that the gas has to travel over the largest amount
of surface before reaching the burning orifices. Or the muffle may be made with a
mixing tube preferably on the inside rising to near the top of the muffle and the gas
may be supplied by a plain pipe opening into the aforesaid mixing tube, the heat of
the muffle and mixing tube inducing the air to enter as an upward current. This
last form is best suited to low gas pressures. For convenience in mounting the
muffle may be made with a 'bayonet' locking slot.
The said burner may be made of metal or other suitable material, but we prefer it
to be made of a refractory fire-proof material.

page_text: 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:
Our invention relates to a new or improved construction of atmospheric or
Bunsen' gas burner suitable for heating and boiling, or cooking, purposes.
"
Our invention has for its object the "regeneration of the gaseous mixture
previous to ignition, and consists in forming the burner in the form of a 'muffle'
or chamber made of suitable earthenware with holes, slits, or other similar orifices
through which the gaseous mixture issues and burns around the 'muffle,' and so
heats such muffle' to a high temperature, which in turn acts as a 'regenerating'
surface for the oncoming mixture inside the muffle. The orifices are at the lowest
portion of the muffle, and so arranged as to cause the flame to partly or wholly
envelope the muffle.
The gas may be supplied to the muffle on the 'Bunsen' system, care being taken
that the mixture of air and gas is conveyed well into the muffle so that the gas has
to travel over the largest amount of surface before reaching the burning orifice. Or
the muffle may be made with a mixing tube rising to near the top of the muffle and
the gas may be supplied by a plain pipe opening into the aforesaid mixing tube, the
heat of the muffle and mixing tube inducing the air to enter as an upward current.
This last form is best suited to low gas pressures. For convenience in mounting the
muffle may be made with a bayonet' locking joint.
And in order that our said invention may be more readily understood and carried
into practical effect, we have hereunto annexed a sheet of drawings and will now
proceed to describe the same with the figures and letters of reference marked thereon.
Similar letters being used to denote similar parts in all the views.
Fig. I is an outside view and half section of our improved burner arranged in a
vertical form.
Fig. 2 is an inverted plan showing the 'bayonet' locking device.
Fig. 3 is an outside view and half section showing our improved burner arranged
horizontally.
Fig. 4 is an underside view of Fig. 3, and
Fig. 5 is an end view of Fig. 3.
In all the views (A) is the muffle or chamber which constitutes the special feature
of our invention, and which is, by preference, formed of earthenware of a suitable kind
or other refractory material. Such muffle or chamber is formed with holes, slits or
other suitable perforations or orifices (B) through which the gaseous mixture issues,
and burning around the muffle heats it to a high temperature which in turn acts as
regenerating surface to heat up the oncoming mixture inside the muffle.
The orifices (B) are, by preference, at the lowest portion of the muffle so that the
flame in rising partially or wholly envelopes the muffle and soon raises it to a dull red
heat.
The mixture of air and gas suitable for use as aforesaid is shown supplied to the
muffle on the 'Bunsen' principle, consisting of a jet (C) to supply the gas, orifice (D)
to admit air into mixing tube (E), which extends nearly to the top of the inside
of the muffle (A) (see Fig. I). For the purpose of attaching this bunsen 'jet
apparatus to the muffle the mixing tube (E) is screwed upon its outer surface and has
a nut (E¹) which may (for the purpose of adjustment) travel thereon. This nut (E¹)
has two or more projections (E2) which can pass through corresponding slots (E³)
formed in the flange (E) of the muffle (A), so that by passing the tube (E) and with
it the nut (E¹) into the inside of the muffle and rotating the tube a quarter of a turn,
(as in 'bayonet 'locking joint) the tube can be locked within the muffle and by
tightening up the nut (F) and washer (FI) the tube is firmly fixed to the muffle.
advisable to carry the tube (E) well up to the top of the muffle to ensure the gaseous
mixture travelling over the largest surface possible of the muffle and also to avoid the
gas lighting back.
It is
In Figs. 3, 4 and 5 we show the same general arrangement of parts applied as a

page_text: horizontal burner, and the same letters of reference being employed as on the previous
figures to denote the several parts, they will be sufficiently described.
Instead of the Bunsen' form of gas supply being used the muffle itself may be
formed with a mixing tube rising from the shoulder X to near the top of the muffle,
and the gas supply be simply allowed to flow without pressure into this tube. The
heated tube is found to create a considerable updraught and secures the efficient
mixing of the gas with the free air supply to the tube. This arrangement is well
suited for low gas pressure when the bunsen' jet cannot be used or when the mixing
tube must be short.
In both the described burners it will be seen that the gas burning around and
almost enveloping the outside of the muffle heats it up to a high temperature, and
the oncoming gas and air having to travel over this highly heated surface its
temperature is raised to a high degree before it issues from the orifices (B), and so is
in the most suitable condition for burning with perfect combustion, and thus we
form a gas burner admirably suited for all kinds of heating and boiling or cooking
stoves.
The muffle (A) may obviously be formed of other material than earthenware, and
that in lieu of holes (B) any other suitable form of opening may be employed, and be
variously disposed.
Having thus particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we wish it to be understood that we
do not confine ourselves to the precise form and demensions of the several parts
described as they may be varied without departing from our invention, and what we
claim is :-
I: The improved regenerative gas burner, consisting of the muffle (A) and perfora-
tions (B), in combination with any suitable form of gas supply, for the purpose set
forth.
2: The muffle (A) with perforations (B), flange (E+) slots (E³) nut (E¹) projec-
tions (E2) and nut and washer (F) and (F¹), forming a locking device for securing the
muffle to a bunsen burner tube, substantially as set forth and illustrated in Figs I
to 5 on the accompanying drawings.
3-The general combination and arrangement of parts forming a regenerating
bunsen gas burner for stoves and the like, as set forth.
