I, EDWIN SHERRING Corn Merchant 39 Hanging Ditch Manchester do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to Lamps for burning Petroleum and other similar inflammable
oil, also improvements in extinguishers to same, and consists in the novel construction
and combination of the parts, hereinafter described and claimed, whereby the Light is
automatically extinguished, and the oil prevented from being spilled if the Lamp
should be overturned, and whereby the heat of the flame is kept from being com-
municated to the oil in the roservoir, and also prevents any flame from being
communicated to the oil, should anyone blow down the Lamp chimney to put out the
light.
I claim for my invention a reservoir for oil, which may be of any desired shape,
and provided with a stand or base. An air chamber which is placed upon the
reservoir, in any convenient manner, the air chamber may be perforated.
A partition which separates the oil reservoir from the air chamber, this partition is
made in the form of a dome or convexity, soldered to the top of the reservoir and
provided with a screw threaded orifice in the centre of dome, the partition may be
inade of other form, such as concave, but the dome or convex form is preferred.
A loose metal cylinder fitting into the base of screw threaded orifice in dome
shaped partition and extending beneath the surface of the oil.
A wick holder or tube with shoulder flange, the wick holder or tube may be made
of any porous or perforated non-inflammable material or metal, the upper end of wick
holder attached to shoulder flange, receives the burner, and the lower end is provided
with a screw thread and extends downwards thro the air chamber and screws into
orifice in dome partition.
For extinguishers I claim, two or more porous or perforated angle pieces pivoted
like swivelled Levers so as to rest on each side of wick tube in burner the upper
portion of angle pieces to be weighted, so that when the Lamp falls over,
the angle
pieces extinguish the light by falling upon the wick or wicks.
The advantages gained by my invention are as follows:-
1. The dome shaped partition, fixed upon the oil reservoir, with the cylinder fitting
into the orifice in the partition, prevent escape of oil when the Lamp is upset.

page_text: 2. The air chamber keeps the heat from descending from the burner to the oil
reservoir and prevents formation of inflammable gas which is so dangerous.
3. The perforations in air chamber supply air all round its circumference which
continually supplies the light with oxygen, and a novel feature in this air chamber is,
that where a circular burner is employed, the air is supplied round the outside of
flame instead of inside, as in old lamps.
4. The porous wick holder is a means of safety if persons blow down the chimny
to extinguish the light, for should any flame descend, it passes thro perforations into
air chamber and thence outside.
5. The porous angle pieces, swivelled Lever fashion on each side of the flame act as
extinguishers when the Lamp is upset.

Improvements in Oil Lamps and Extinguishers.
I, EDWIN SHERRING, of 39 Hanging Ditch, Manchester, Corn Broker, 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 relates to lamps for burning petroleum and other inflammable oils,
also to improvements in extinguishers for the same, and consists in the construction
and combination of the parts hereinafter described and claimed, whereby the light or
flame is automatically extinguished on the occurrence of accident, and the oil may
be prevented from being spilled should the lamp be overturned, and whereby the heat
of the flame is kept from being communicated to the oil in the reservoir, either in
burning, or in case of blowing down the chimney.
On reference to the accompanying drawings it will be seen that I carry out my
invention by forming a reservoir a, a, in the ordinary or any convenient shape or
form and which may be provided with a stand or base according to the design
required. By means of a partition in the reservoir, or diaphram b, b, I form an air
chamber above the oil in the reservoir. This partition b, b, and air chamber c, c, are
shown dome shape or in convex form, which is the form 1 most prefer; but other
forms may be adopted for one or both. Openings or perforations of any shape may
be made in the upper shell d, d, for the admission of air into the chamber, or the
openings might be underneath this shell or hood which could overlap the reservoir
for the purpose. The partition b, b, is soldered or otherwise connected to the reservoir,
and provided with a screw threaded orifice e, e, in the centre of the dome or there-
abouts. I also provide a loose metal cylinder ff, fitting into the base of the screw
threaded orifice in the dome shaped partition, and extending below. the surface of the
oil, by preference to near the bottom of the reservoir.
Also I provide a wick holder or tube 9, 9, with shoulder flange g¹, g'. The wick
holder may be made of any non inflamable material or metal and may be
porous or perforated. The upper end of the wick holder receives the burner, and the
lower end is provided with a screw thread, and passes through the air chamber and
screws into the orifice provided in the dome partition or covering. The wick holder
may be flat as shown or may be round, or it may be of elliptical or oval form.
The extinguisher h, h, is composed of two or more porous or perforated angle pieces,
pivoted like swivelled levers, upon the wick tube of the burner as shown in Fig. 1,
so that when the lamp turns over, or is held at a certain angle, these angle pieces or
extinguishers or one of them will tumble over and cover the flame or top of the wick
by the action of gravity. In a flat flame burner two such angled swivelled levers
are sufficient to form an extinguishing apparatus, and even one may be employed ;
but in a round or hollow wick burner it may be desirable to adopt more than two,
according to the nature of the design of such burner. In lieu of these angle pieces
being pivoted on the wick holder itself, they may be pivoted on a separate sliding
piece or case or tube which may be made detachable from the wick holder.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The dome or other shaped partition fixed upon the oil reservoir and forming an
air chamber through which the air for combustion is supplied to the flame for the
purpose and in manner substantially as shown and described.
2. The swivelled or pivoted angle pieces or levers attached to the wick holder, and
detachable or not, forming automatic or manual extinguishers for the purpose and in
manner substantially as herein shown and described.
3. The combination of two or more of the parts named; the partition forming
the air chamber; the cylinder fitting into the orifice; the perforations in or openings
underneath the air chamber; the porous wick-holder or wick-holder with pores or
openings therein; the swivelled angle pieces forming the extinguishers; when such
are employed in the manufacture of lamps for oil burning purposes, in manner
substantially as shown and described.
