Improvements connected with Gas Burners.
AND
We, CLEMENT BERNARD VOISEY M.D. London, of 108 Hartington Road,
Liverpool, in the County of Lancaster, EDMOND WALTER TYRRELL RICHMOND
of Academy Street, Warrington, Managing Director, and RICHMOND
COMPANY LIMITED, Gas Appliance Manufacturers, also of Academy Street,
Warrington, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
:―
This invention has reference more particularly to gas burners employed for
heating, as in gas-fires, or fire-places in which atmospheric gas-burners are used;
and it has for its object principally to provide in connection with said fire-places
or burners means by which, in regulating or diminishing the flame at the burner,
the firing back or extinguishment of the burner is prevented.
According to this invention, a means is provided in connection with the gas
supply pipe of the burner, by which when gas is turned on or the supply opened by
the tap or ccck, or conversely turned down, an aperture is opened thereby, which
will supply such a quantity of gas that no matter what amount of diminution of
the main supply takes place, sufficient will be supplied by this special means to
prevent the back firing of the burner or its extinction; and this quantity may with
advantage be the minimum which will keep the burner properly lighted.
In one arrangement, a device according to this invention, would comprise a tap
or cock controlling the main supply, and a second tap or cock controlling a separate
minimum supply through a separate passage, and adapted to be operated, that is
opened, when the main supply tap or valve is being opened, so that a proper supply
is maintained no matter how much the main supply be diminished. This may be
done by a projecting part, arm, lever, or equivalent means, which when the main tap
is opened acts upon and opens said secondary tap, and in the regulating or
diminishing of the main supply, is not acted upon by the main supply tap, but
remains fully open, it being closed by hand when it is desired to totally extinguish
the burner. When the primary tap or valve is open the secondary tap or valve
cannot be closed. In one construction, these parts are formed in one device or
structure; while in another, the two regulating or gas supplying taps or valves are
separate devices.

Improvements connected with Gas Burners.
We, CLEMENT BERNARD VOISEY, M.D. London, of 108 Hartington Road,
Liverpool, in the County of Lancaster, EDMOND WALTER TYRRELL RICHMOND
of Academy Street, Warrington, Managing Director, and RICHMOND AND
COMPANY LIMITED, Gas Appliance Manufacturers, also of Academy Street,

page_text: Warrington, in the County of Lancaster, 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 has reference more particularly to gas burners employed for
heating, as in gas-fires, or fire-places in which atmospheric gas-burners are used;
and it has for its object principally to provide in connection with said fire-places or
burners means by which, in regulating or diminishing the flame at the burner, the
firing back or extinguishment of the burner is prevented.
According to this invention, a means is provided in connection with the gas
supply pipe of the burner, by which when gas is turned on or the supply opened by
the tap or cock, or conversely turned down, an aperture is opened thereby, which
will supply such a quantity of gas that no matter what amount of diminution of the
main supply takes place, sufficient will be supplied by this special means to
prevent the back firing of the burner or its extinction; and this quantity may
with advantage be the minimum which will keep the burner properly lighted.
In one arrangement, a device according to this invention, would comprise a tap
or cock controlling the main supply, and a second tap or cock controlling a separate
minimum supply through a separate passage, and adapted. to be operated, that is
opened, when the main supply tap or valve is being opened, so that a proper supply
is maintained no matter how much the main supply be diminished. This may be
done by a projecting part, arm, lever, or equivalent means, which when the main
tap is opened acts upon and opens said secondary tap, and in the regulating or
diminishing of the main supply, is not acted upon by the main supply tap, but
remains fully open, it being closed by hand when it is desired to totally extinguish
the burner. When the primary tap or valve is open the secondary tap or valve
cannot be closed. In one construction, these parts are formed in one device or
structure; while in another, the two regulating or gas supplying taps or valves are
separate devices.
The drawings hereto annexed shew a device according to this invention, in the
form we at present prefer.
:
Figure 1 is a plan shewing both the tap controlling the main supply, and that
controlling the minimum supply, open.
Figure 2 is a plan shewing both these taps closed. And
Figure 3 is an end view of the device.
Referring now to these drawings, a are the inlet and outlet branches of the main
or primary tap; b is the plug case thereof; c is the plug working in the case b;
and c is the plug handle. d are branches leading from and into the main tap
branches a, and by which the minimum quantity of gas is supplied when the main
or primary tap is closed; e is the plug case of the minimum supply tap on the
branches d, and the plug working therein; and is the handle of the plug f.
h is a cam shaped projecting part on the upper part of the plug c, and i is a ledge
upon the upper part of the plug f; these two parts being in the same horizontal
plane, and adapted to co-act as hereafter described. ; is a projection on the primary
tap acting in connection with the part hand serving as a stop to limit the
movement of the plug e, in both directions, to 90 degrees.
In the position of the plugs shewn in Figure 2, both taps controlling the main
supply and the minimum supply are closed to their respective passages a and d, so
that no gas can be supplied to the burner in connection with which the device is
used. Then to supply gas to the burner, the handle c' of the main supply tap is
turned in the direction of the arrow in Figure 2, the effect of which is that the end
of the cam shaped projection being arranged in relation to the ledge i on the
minimum supply tap plug as shewn that plug is moved round the same degree,
practically, as the main tap plug, namely, 90 degrees, into the position shewn in
Figure 1. In this condition both taps are fully opened and gas full on; then,
whatever may be done with the n ain tap in the way of turning down the gas or
regulating the supply, it does not affect the minimum supply tap plug f, that plug
remaining fully open; and assuming the plug c were turned backwards the full

page_text: 90 degrees, turning off the whole main supply of gas, the minimum supply plug f
will still be fully open, and a supply of gas to the burner through its passage d
fully sufficient to give such a pressure of supply at the burner as to prevent back-
firing due to diminution. Whatever the lower limit of pressure at which a gas
burner used in connection with the controlling device may be considered safe and
right to be worked under, the capacity of supply of the by-pass or secondary
passages d, and tap plug f, must be made correspondingly.
As shewn in the drawings, the cam h is made of practically the same radius for
that portion which works in connection with the ledge of the minimum supply tap,
the said ledge i being of concave form, corresponding substantially with h. By
this means, the plug cannot be moved by its handle f¹ when the plug c or the
main tap is fully opened, or substantially so. By this means mistakes cannot be
made with respect to the right tap to be used, when it is desired to diminish the
supply of gas from the full supply, it being only possible to turn the minimum
supply tap so as to shut off all supply of gas to the burner when the main supply
tap is closed.
This device or tap may be placed at any suitable or convenient position on the
gas supply in relation to the burner it is employed in connection with.
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 improvement connected with gas burners, consisting of a device for
controlling the supply of gas thereto, comprising a tap or valve for controlling a
main or full supply, and a second tap or valve for controlling a separate minimum
supply, the minimum supply being opened or effected by the moveinent of the main
supply tap, substantially as herein described.
2. The device for employment in connection with gas burners comprising a tap
or valve for controlling the main or full supply, and a tap or valve for controlling
a minimum supply, the latter being adapted to be opened by the former when the
main supply is being opened, and to be left open and unaffected by the movement
of the main supply tap thereafter: as set forth with reference to and as shewn in
the drawings hereto annexed.
