PROVISIONAL SPECIFICATION.
Improved Means and Apparatus for Regulating the Strength of the
Blast of Bunsen Flame.
We, RICHARD THOMAS GLOVER and JOIN 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 relates to improved means and apparatus for regulating the
strength of the blast of Bunsen flame.
To carry this invention into practice, a blast tube for atmospheric gas flame is
operable by rack and pinion, or the gas jet or spit nozzle is operable singly or
combined to regulate the amount of air inlet, and also if desired by screw pin
the quantity of gas supplied.
The upper part or outlet of the flame tube is provided with an angled plate or
a deflector, adjustable by screw or rack for being slid more or less over the outlet
so that the strength of the blast can be increased or diminished by a simple move-
ment and in conjunction with the regulation of the air entry and the amount of
gas supply.
By this invention, an ordinary Bunsen or atmospheric flame of high intensity
and power can be produced with a reduction in the quantity of gas.

We, RICHARD THOMAS GLOVER and JOHN GEORGE GLOVER, of the Firm
Thomas Glover & Co. Ld., 214 to 222, St. John Street, Clerkenwell, London,

what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
. This invention relates to improved means and apparatus for regulating the
strength of the blast of Bunsen flame.
To carry this invention into practice, a blast tube for atmospheric gas flame is
operable by rack and pinion, or the gas jet or spit nozzle is operable singly or

page_text: the quantity of the gas supplied. The upper part or outlet of the flame tube is pro-
vided with an angled plate or a deflector, adjustable by screw or rack for being
slid more or less over the outlet, so that the strength of the blast can be increased
or diminished by a simple movement and in conjunction with the regulation of
the air entry and the amount of gas supply
By this invention, an ordinary Bunsen or atmospheric flame of high intensity
and power can be produced with a reduction of the quantity of gas.
Our invention will be clearly understood by reference to the annexed drawings.
Figure 1 sectional elevation of the apparatus with the gas spit supply" pin and
the air blast tube capable of regulation as desired.
Figure 2 sectional elevation of similar apparatus with gas spit supply tube
and, or, air blast tube capable of regulation, both apparatus showing the adjust-
able deflector plate.
Figure 3 exterior elevation of the apparatus shown at Figure 2AZAS
A, air blast tube provided with air inlet B and adjustable to close the air inlet
opening B more or less as desired by means of the rack C-and turn button. D
which with its pinion E is supported by a rod F secured to the base well or foot G
and passing through steadying rings H and I in which the tube A has an up and
down sliding motion, the lower end of the tube A encircling the nozzle of the
gas spit tube J which may be in a piece with the base or foot G, as at Figure 1,
or adjustable in the foot G by rack K and pinion L operable by the turn button M,
as at Figures 2 and 3, either alone or in conjunction with the adjustability of the
blast tube A, the length of which forms a mixing chamber for the gas from J
and air from B to ensure a perfect Bunsen or atmospheric flame at the outlet N.
The base or foot G is provided with a scored nozzle P, or it may be a pear
shaped nozzle for attachment of a flexible tube used for supplying the gas from
any source, the apparatus being portable and standing on, say, three or four
legs such as Q, Q, two of which only are shown.
According to Figure 1, the gas spit nozzle J has an adjustable pin R screwed
into the base & to regulate or to shut off the supply of gas to the tube J, said
pin being operable by the turn button or screw head S, otherwise the nozzle P
of Figures 2 and 3 would have a tap by which the regulation or shut off of the
gas supply could be effected.
The apparatus thus far serves for regulation of air and of gas at will, either
by placing the tube A in an adjustable position, or by adjusting the gas supply
such as by operating the pin R or the tube J as explained which is a novelty
in or connected with ordinary gas and air blast burners, and where greater inten-
sity of the Bunsen flame is required, we by the angularly arranged deflector plate T
over the tube A and against which the flame is caused to impinge and be cast
off at an angle creates by the scattered action of the flame and the fresh supply
of air thereto at this point, coupled with the heat imparted to the deflector
plate T, raises the heat of the flame very considerably and produces that roar
which is so familiar to users of compressed air Bunsen flame or Bunsen burner
apparatus and in which a pump is generally employed for the purpose of getting
up pressure and then to use that blast for sucking the gas from the supply tube
and forcing it up the blast pipe, such as A.
This deflector plate T of preferably steatite or other refractory body in a
frame U is adjustable as to the distance it shall project over the tube A is regu-
lated by the screw V and button head W supported by the bracket X permanently
secured to the tube A as shown, said deflector plate only being adjusted over the
flame when great intensity of heat is required and under ordinary atmospheric
conditions.
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. The hereinbefore described means and illustrated apparatus for regulating

page_text: the supply of air and the supply of gas to a Bunsen or atmospheric burner con-
sisting of the combination of appliances by which said supplies are determined,
as set forth.
2. In combination with an ordinary atmospheric or Bunsen flame apparatus,
the adjustable deflector plate operable in the manner and for the purpose
described.
3. A Bunsen or atmospheric flame apparatus with adjustable blast tube A, ad-
justable gas spit nozzle pin, or adjustable gas nozzle, and top adjustable deflector
plate all combined substantially as represented on the annexed drawings.
