Improvements in or relating to Gas Heaters, such as Stoves
and the like.
We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm Thomas
Glover & Co. Ld., 214 to 222, St. John Street, Clerkenwell, London, Gas Meter
Manufacturers, do hereby declare the nature of this invention to be as follows:--
This invention has for object, certain means and appliances so arranged and
operated that the quantity of gas to be consumed can be regulated, also the
amount of openings or outlets from the mixing chamber and consequently the
spread of flame from what may be termed the smallest to a large area of surface
flame of the Bunsen or atmospheric kind according to the uses to which such
a flame and the intensity of it may be required.
For the purposes of this invention, a tube prepared to any desired shape is
provided with a number of slots or apertures, and contains a gauze liner for the
free passage of a mixture of gas and air for an outside flame therefrom without
fear of back lighting, a portion of said tube has the air hole in proximity to a
gas jet or spit nozzle in which is a screwed in cone capable of movement by an
outside button to regulate the quantity of gas passing into the chamber.
The mixing chamber or tube is turnable or shiftable in an outer tube or box
also provided with corresponding slots or apertures in such manner that the
solid parts of one may be moved over or under the openings of the other and so
be shut off more or less according to desired amount of flame. The above may
be employed. singly or in multiple order and arranged in any way found con-
venient for heating.

For the purposes of this invention, a tube prepared to any desired shape is
provided with a number of slots or apertures, and contains a gauze liner for the
free passage of a mixture of gas and air for an outside flame therefrom without
fear of back lighting, a portion of said tube has the air hole in proximity to a
gas jet or spit nozzle in which is a screwed in cone capable of movement by an
outside button to regulate the quantity of gas passing into the chamber.
The mixing chamber or tube is turnable or shiftable in an outer tube or box
also provided with corresponding slots or apertures in such manner that the
solid parts of one may be moved over or under the openings of the other and so
be shut off more or less according to desired amount of flame...
The above may be employed singly or in multiple order and arranged in any
way found convenient for heating.
Our invention is represented on the annexed sheet of drawings.
Figure 1 part sectional elevation of the gauze container tube and showing. the
slots through which the mixture of gas and air for a number of Bunsen or atmos-
pheric flames can be obtained.
Figure 2 plan of the apparatus complete with the slots of the inner tube partially
cut off from corresponding slots of the outer tube in which said inner tube can
be moved round or be withdrawn as desired.

Figure 4 end elevation of the apparatus.
A tube with slots or apertures B in a portion of its circumference and at slight
distance apart. C, inner liner of fine wire gauze therein, so that back flash of the
gas mixture is prevented. The inner end of the tube A is permanently closed
but the other 1 is plugged by E, or it may be by a screwed in end piece to
carry the gas spit nozzle F, the point of which projects over the air inlet G of
the tube A. The gas spit nozzle F is provided with a screw regulating pin II
passed through the shoulder I for closing the gas passage more or less on the
button head being turned, the shoulder being part of or attached to the gas
supply branch or nozzle K on which the end of flexible tube can be slipped as
desired. This branch may have a regulating and shut off tap L.
The tube A just fits the barrel M of the stand formed from and between end
bands N, N, which have feet P, P, to bear on a bench or table, the bands have
also a pair of arms Q, Q, connected by rails R, R, which constitute a stand for
supporting a kettle or other vessel containing liquid to be heated. The flames
issuing from the slots B, B, being almost contiguous, present a large heating
surface.
The slots S, S, of the barrel M coincide with those B, B, of the tube A, and
by turning the tube A more or less in the barrel M, the flames increase or
diminish proportionately. The rotation of the tube A can be limited by the
pin $1.
By this invention, the suction of air may be varied by increasing or diminishing
the opening of the orifice for the ignition point, so that when the hole is fully
open, the mixture is so regulated by the screw spit that the flame is just on the
roar, and when the tube is turned so that the orifice is half way, the same result
may be obtained if the pressure diminishes or a soft flame is required at the first
pressure.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:.
_
1. An atmospheric flame heater apparatus consisting of inner rotatable tube A
lined with fine wire gauze C, and provided with slots B at intervals, the tube A
constituting a gas and air mixing chamber, and movable within a barrel M,
as and for the purposes explained.
2. An atmospheric flame heater apparatus consisting of a stand having a
slotted barrel M in which a rotatable gas and air container is fitted and by which
the suction of air may be varied by increasing or diminishing the opening of
the orifice for the ignition point so that when the hole is fully open the mixture
is so regulated by the screw spit that the flame is just on the roar, and when the
tube is turned so that the orifice is half way, the same result may be obtained
if the pressure diminishes, or a soft flame is required at the first pressure.
