Improved Means for Automatically Extinguishing Oil Lamps.
I, SAMUEL GREGORY, of 74 East Lane, Bermondsey in the County of Surrey
Carpenter & Joiner, do hereby declare the nature of this invention to be as
follows:-
-
The invention consists of a case, to slide up the wick burner.
The said case, having a hood, or cap, so arranged, that on the case sliding up,
hood, or cap, turns over the burner, and extinguishes the flame.
To accomplish this, the sliding case is worked by a lever-bar, pivoted on to the
ventilator, and held in its position by a fulcrum joint.
On this lever-bar is a pin, or stud. A spring (acting in conjunction with this
lever-bar,) is fixed to the outer part of the lamp, or to an arm which may be fixed
for the purpose of attaching a hanging check-lever, having a shoulder or notch, to
receive the pin or stud, to act as a check, and keeps the lever-bar (that works the
case) in its position.
The hanging check-lever, is fitted at the end with a cup, to receive a ball, the
weight of which, holds the check-lever in its position.
In the event of the lamp being overturned, or tilted to a dangerous degree, the
ball, falls from the cup, and releases the check-lever, which liberates the lever-bar,
sending up the sliding case, and so extinguishing the flame.

COMPLETE SPECIFICATION.
Improved Means for Automatically Extinguishing Oil Lamps.
SAMUEL GREGORY 74 East Lane Bermondsey Surrey Carpenter 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:-
Improved means for automatically extinguishing oil lamps, preferably those fitted
with one or more flat wick burners."
In the event of the lamp being turned over, or tilted to a dangerous angle, or
dropped, the flame is immediately automatically extinguished.
To accomplish this, I employ the following means, shewn in the accompanying
drawings, in which
Fig. 1, is a sectional elevation showing an ordinary lamp burner fitted with my
improvements, and with the extinguisher in its normal position when the lamp is
burning.
Fig. 2, is a transverse section of same.
Fig. 3, is a view showing the extinguisher in its position when light has been
extinguished.
manding parts in all the figures.

page_text: Fig. 2, pivoted at d, to the sliding case or tube b, the ends of these cheeks have
holes (Fig. 2) through which a wire e passes.
e, is the wire that passes through the cheeks c', of the cap or flap c, the said wire
being then bent, so as to engage with spindle or rod which rod is fixed at the
ends, to the ventilator part of the lamp burner.
is a lever, pivoted at, on the ventilator, one end of this lever g, passes
through the socket ', on the sliding case, or tube b, the other end of the lever,
having attached thereto a ball, by a chain p', (this ball may be attached to any other
convenient part of the lamp, as the attachment is merely to prevent the loss of the
ball).
i, is a catch or stud, fixed to, or in one, with the lever 9.
, is a bracket or arm, fixed to any convenient part of the lamp or burner, having
a pink, to which is pivoted the hanging check lever m.
7, is a spiral spring, and ', is a guide rod for same, one end of this guide rod, is
fixed to the bracket j, the other end being slotted, so as to clear the lever g.
The hanging check lever m, is formed with a shoulder, or notch », upon which
the catch or studi, rests. The end of the check lever m, is bent outward, and is so
shaped as to form a seating o, for the ball p, which ball by its weight keeps the
hanging check lever m, in its normal position, and so preventing the lever 9, from
being forced downward by the spring 1.
The action of extinguishing the light is as follows,
On the lamp being tilted or turned over in any direction, (as shown in Fig. 3,)
the ball, slips, or rolls out of the seating o, which immediately releases the
hanging check lever m, and allows the catch or stud i, on the lever to pass by
the shoulder or notch n, and by the action of the spiral spring 1, the outer end of
the lever g, is forced down, and its other end is thereby enabled to raise the sliding
case or tube . At the same time, by reason of the wire e, the cap or flap c, is lifted
and turned over the wick, thereby extinguishing the flame.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1. In automatically extinguishing lamps, the combination of the pivoted hanging
check lever m, constructed with a shoulder, or notch », with a pivoted lever g,
having a catch or stud i, engaging with the shoulder n, substantially as shown and
described.
2. In automatically extinguishing lamps, the combination of hanging check
lever m, pivoted lever 9, shoulder 21, and catch, with the spiral spring 1, substan-
tially as shown and described.
3. In automatically extinguishing lamps, the combination of hanging check
lever }}, ball P, pivoted lever g, spring 1, cap or flap c, wire e, substantially as shown
and described, for the purposes as set forth.
