IMPROVEMENTS IN THE CONSTRUCTION OF LAMPS FOR BURNING PARAFFIN AND OTHER OILS
Year: 1885

page_text: I, GEORGE RAYNER, of 328 Mare Street, Hackney, in the County of Middlesex,
Provision Dealer, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF LAMPS FOR BURNING PARAFFIN AND OTHER OILS," to be
as follows
-
The object of my invention is to manufacture lamps for burning paraffin and
other oils in an improved manner, by fitting them with simple and efficient means
for extinguishing the same such means being rendered automatic when an accident
occurs, such as the falling or overturning of the lamp
In carrying out my invention I fit the wick tube or tubes with sliding flaps or
covers, which close over the wicks when they rise, and thereby extinguish the
flame or flames These flaps or covers are pressed upwards by suitable springs,
and, when they are drawn down or lowered below the tops of the wick tubes,
such tubes hold the flaps apart; but, when allowed to rise, these flaps close over
the wicks.
Between the wick tubes, or on the outer side of such wick tubes (or tube, as
the case may be) I fit a small horizontal rod, in the gallery, the outer end of which
projects beyond the gallery, and terminates in a finger catch. The inner end of
this rod is connected with a bell crank, or other suitable device, for drawing down
the extinguisher flaps The outer end of the rod is also fitted with a catch which
traverses a small rectangular box, in which it slides A small cubical piece of metal
or plug is attached, by a chain, to the gallery This plug may be made in an
ornamental form or surmounted with a figure representing a head or bust, or other
suitable design.
When the horizontal rod is drawn back by the finger, it lowers the extinguisher
flaps, and, while in this position, if the plug is inserted in the rectangular box, the
flaps are retained in such position, and the lamp can then be lighted, and will
continue to burn until the plug is removed, when the springs will immediately
raise the extinguisher flaps, and extinguish the flames
I usually make the plug about three eighths of an inch square at the bottom,
and about three quarters of an inch in height (more or less) This plug is therefore
very easily removed from its position, either by the finger, or the tilting or
upsetting of the lamp, by which means it becomes displaced, and the lamp becomes
instantly extinguished, by the springing back of the rod, and the rising of
the flaps.

I GEORGE RAYNER of 328 Mare Street, Hackney, in the County of Middlesex,
Provision Dealer do hereby declare the nature of my Invention for IMPROVEMENTS
IN THE CONSTRUCTION OF LAMPS FOR BURNING PARAFFIN AND OTHER OILS, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
-
The object of my invention is to manufacture lamps for burning paraffin and
other oils in an improved manner, by fitting them with simple and efficient means
for extinguishing the same, such means being rendered automatic when an accident
occurs, such as the falling or overturning of the lamp
In carrying out my invention, I fit the wick tube or tubes with sliding flaps or
covers, which close over the wicks when they rise and thereby extinguish the
flame or flames These flaps or covers are pressed upwards by suitable springs,
and when they are drawn down or lowered below the tops of the wick tubes, such
tubes hold the flaps apart but, when allowed to rise, these flaps close over the
wicks
Between the wick tubes, or on the outer side of such wick tubes (or tube or
circular wick tube as the case may be) I fit a small horizontal rod, in the gallery,
the outer end of which projects beyond the gallery, and terminates in a finger
catch The inner end of this rod is connected with a bell crank or cranks, or other
suitable devices, for drawing down the extinguisher flap or flaps The outer end
of the rod is also fitted with a catch, which traverses a small rectangular box, in
which it slides A small cubical piece of metal or plug is attached, by a chain, to
the gallery This plug may be made in an ornamental form or surmounted with
a figure representing a head or bust, or other suitable design
When the horizontal rod is drawn back by the finger, it lowers the extinguisher
Baps, or tube and, while in this position, if the plug is inserted in the rectangulai
box, the flaps or tube are retained in such position, and the lamp can then be
lighted, and will continue to burn until the plug is removed, when the springs will
immediately raise the extinguisher flaps or tube and extinguish the flames
I usually make the plug about three eighths of an inch square at the bottom, and
about three quarters of an inch in height (more or less) This plug 18 therefore
very easily removed from its position, either by the finger, or the tilting or
upsetting of the lamp or by a knock or slight blow, by which means it becomes
displaced, and the lamp is thereby instantly extinguished, from the springing back
of the rod, and the rising of the flap or flaps or tube
And in order that my said invention may be more clearly described and
ascertained, reference is hereby made to the accompanying drawings, wherein two
arrangements for carrying the same into effect are shewn with a double wick, by
way of example, and in which drawings similar letters of reference indicate
corresponding parts
Fig 1 is a perspective view of a portion of a double wick lamp, fitted with my
invention Fig 2 is a section of the same, Fig, 3 is a similar section in an inclined

page_text: position, with the extinguisher flaps raised, and Fig 4 shews a method of applying
the invention to a lamp with a circular wick. au are the wick tubes, b b are the
flaps for extinguishing the flames, c c are two springs which press against lugs g
attached to the flaps bb, these springs not only press the extinguishing flaps
upwards, but also inwards, when raised so as to overlap the tubes and extinguish
the flames, as shown in Fig 3 d is a tube attached to the lamp, under the gallery
In this tube there is a rod e having a finger catch f for drawing the rod outwards
to the position shewn in Figs 1 and 2 h is a piece of metal which is placed in
the space formed for its reception at the end of the tube, as shewn This block h
may be surmounted by a small globe of metal, as shewn, or may have a bust or
other ornamental design, the intention being that its centre of gravity shall be
sufficiently raised to insure its falling out of place when the lamp is inclined at a
considerable angle, but that it should not fall out of position, when slightly inclined,
as in ordinary cases of removal from place to place when carried in the hand el 18
a lip attached to the bar e against which the block himpinges
The block h 19
attached to the gallery by the chain k By throwing the block h out of position,
by the finger, the lamp may be extinguished at any time, is a bell crank lever by
means of which the horizontal movement of the rod e 1s converted into and
caused to impart vertical movement to the flaps b b as shewn
The amount of inclination or disturbance of the lamp necessary to displace the
block h may be provided for in manufacturing my improved lamps, and may be
adjusted either for acting when a considerable angle of inclination has been
assumed or only when a blow or concussion occurs
I do not confine myself to any particular forin of flaps for extinguishing lamps,
or to any particular description of spring for bell crank connection, as the same
may be greatly varied, and various forms of extinguishing tubes and spring flaps
may be used for lamps having circular wicks, an example of which is shewn in
Fig 4 in which the extinguisher consists of an outer tube b¹ This outer tube is
pressed upwards by a spring c¹ which may be a spiral or other spring or springs
held down by a similar arrangement to that herein before described
Figure the chunk is omitted because the gallery is omitted for greater clearness
In this
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 manufacture and use of paraffin lamps having a tube d containing a
rode with finger catch fand lip e', connected with the flaps b b or tube b¹ sustained
by springs c c c and moveable block h linked to the chain k, substantially as and
for the purposes herein before described and shewn on the drawings
2 The combination and arrangement of mechanism for instantaneously
extinguishing lamps, substantially as herein before described and shewn on the
drawings
