HERBERT EDWIN WILLIS, of 260, Euston Road, London, and JOHN PITT BAYLY,
of 30, Dudley Grove, Paddington. "IMPROVED APPARATUS OR APPLIANCE FOR:
EXTINGUISHING THE FLAME IN HYDROCARBON OIL BURNERS."
This Invention consists of a contrivance for extinguishing the flames of the
triangular wick burner without lowering the cottons in the wick tubes.
The object of the Invention is to extinguish at one time the three flames of the..
three wicks, arranged in a triangular form, for burning petrolium or other mineral'
oils, and consists of a case having half way up it double flaps, doors, or covers,,
closing towards the centre from the outsides by means of a double steel spring
attached or rivetted at the end of each case or parallel tube which fits over the .
wick tubes, and is made to slide up & down by means of a lever working on a pivot
attached to the outer casing of the burner, viz., the wind guard; thus the triangular
extinguisher slides up the wick cases beyond the flames when the double spring,
produces its power by closing the two flaps or doors towards the centre, thereby
excluding the air; thus the flames become extinguished.
Having now described the nature of this Invention and how it is to be performed,
we therefore claim the following:
:-
First. We claim the shape which slopes to a point at the upper part of the case
towards the centre on each side of the longitudinal ends.
Second. We claim the two flaps, doors, or covers closing towards the centre by
means of a double spring attached to one of the narrow ends of the extinguisher
case.
Third. We claim the extinguisher for the triangular shaped arrangement of three
wicks, each extinguisher case being attached to one another by means of a tripod.
or other shaped piece of metal.

HERBERT EDWIN WILLIS, of 260, Euston Road, London, and JOHN PITT BAYLY,
_ of 30,--Dudley Grove, Paddington." IMPROVED APPARATUS OR APPLIANCE FOR
EXTINGUISHING THE FLAME IN HYDROCARBON OIL BURNERS."
This Invention relates to an improved appliance for extinguishing the flame in
hydrocarbon oil burners and obviates the necessity and danger of lowering the
wicks in the wick tubes, and is specially intended for burners with three wicks
arranged in a triangular form by means of a lever working on a pivot attached to
the outer casing or wind guard of the burner, which enables the extinguishing
apparatus to be raised above the wick and lighted cottons, thereby excluding the
air and extinguishing the flames.
The triangular extinguisher consists of three cases of metal, which form an outer
covering to the three wick tubes and slide up and down same. On each side of these
cases is attached a flap, door, or cover working on pivots, both of which on each of
the three cases close simultaneously towards the centre, forced by a double steel
spring attached or rivetted to one end of the above mentioned cases or parallel
tubes which slide up and down.
The three cases are attached to each other by a tripod or other shaped piece of
metal, and is constructed to slide the three cases up or down the wick tubes by
means of a lever working on a pivot, one end of which is attached to the tripod.
the other being exposed outside the wind guard or casing underneath the gallery
ring of burner, to be used for raising or lowering.
This Invention will be better understood by reference to the accompanying Sheet
of Drawings, vis..—
A, A, A, are the extinguishing cases sliding up and down the wick tubes G, G, G,
and attached to one another by the tripod shaped piece of metal B.
B is the tripod shaped piece of metal attaching all three extinguisher cases together,
and beneath the same the end of the lever is attached to allow the lever to raise or
lower the triangular extinguisher.
C is the double steel spring attached or rivetted to the ends of each extinguisher
case.
D, the lever worked on a pivot attached to the wind guard for raising or lowering
the triangular extinguisher.
E, the top of extinguisher case where the two doors, flaps, or covers close towards
this centre simultaneously.
F is the door, flap, or cover hinged on each longitudinal slide of each extinguisher
case.
We are aware that extinguishers have been constructed before to operate by
means of a lever or raised by a spindle on a crank or ratchet, with one flap working
from the outside of the extinguisher case towards the other or straight side, and
worked by a single spring (thereby crushing the charred wick), which is not new,
nor do we pretend to claim it.
Our device is constructed with two doors, flaps, or covers hinged on each longi-
tudinal side of each case, which close towards the centre by means of a double
spring, and raised to a required height by the lever before closing towards one
another and meeting in the centre simultaneously, thus saving the charred wick
from being crushed.
Having now described the nature of our said Invention and the manner in which
the same is used on the triangular or three wick burner arranged in a triangular
form, we therefore claim the following as the Invention secured to us by our said
Letters Patent,—
Firstly. The shape of extinguisher case, which slopes to a point at the upper part

page_text: of the case at each end, and which has the following advantages over all other
extinguishers:-The case is constructed to slide up to the required height above the
wick tube and burnt cotton before the two doors, flaps, or covers are closed; thus
we save the great defect of crushing the charred wick or burnt cotton.
Secondly. The two flaps, doors, or covers which close towards the centre by
means a double steel spring attached to the narrow ends of extinguisher case.
Thirdly. The extinguishing apparatus for the triangular shaped arrangement of
three wicks, each extinguisher case being attached to one another by means of a
tripod or other shaped piece of metal.
In witness whereof, we, the said Herbert Edwin Willis and John Pitt
Bayly, have hereunto set our hands and seals, this Twenty seventh day
of May, in the year of our Lord One thousand eight hundred and seventy-
nine.
