JAMES SHEPHERD of No. 27 Plymouth Avenue Manchester in the County of
Lancaster Engineer and THOMAS SHEPHERD of 210 Moreton Street Longsight,
Manchester in the County of Lancaster, Engineer, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to that class of lamp used with mineral and other vaporizing
oils and where the burner is fixed above or below the receptacle containing the oil
and is supplied with a burning wick, regulator and chimney.
It consists in applying to such lamps an extinguisher that can be used by band for
the purpose of putting out the flame of a lamp when required, and also to render it
self-acting in extinguishing a lighted lamp in the event of its being accidentally
overthrown.
An extinguisher mado in accordance with this invention consists in attaching to or
fixing round the wick, tube or holder of a lamp a vertical slide or casing of any shape
to suit the wick tube or holder.
To one side of the vertical slide is attached a swivel shutter or extinguisher (the size
and form depending upon the dimensions of the slide). The swivel shutter or extinguisher
is hung from centres or journals about mid-distance of its depth in suitable holes or bearings
in the sides of the sliding case. When the lamp is lighted the extinguisher is in a
vertica! position against the side of the wick tube or holder, its top edge being a little
below the top of the holder. To the bottom. of the extinguisher is attached a fine
flexible wire or chain which rises to the top part of the metal bonnet or cap surround-
ing the burner, thence passing externally through a hole in the bonnet or cap made
or the purpose, or the chain or wire can be attached to a short lever of any required
orm working upon centres through a fine slot in the side of the bonnet or cap the
external length of the chain or wire descending down the side of the lamp to any
equired distance. To the end of this chain or wire is attached a metal weight
ufficiently heavy when held in suspension to raise the sliding casing with its swivel
hutter or extinguisher from the bottom of the wick holder to a position above the
op of the wick. At any convenient and suitable part of the basement or frame-
work of the lamp there is formed a projection or stand upon which the weight is held

Lancaster, Engineer, and THOMAS SHEPHERD of 210 Moreton Street Longsight
Manchester in the County of Lancaster, Engineer, do hereby declare the nature of
this invention and in what manner the same is to bo performed, to be particularly
described and ascertained in and by the following statement :-
The object of our invention, is to prevent accidents arising through the use of lamps
when burning mineral and other vaporizing oils, such accidents springing from various
causes but principally from the upsetting of lighted lamps and blowing down the
chimney of a lighted lamp to extinguish the flame.
Our invention consists in applying to lamps using any vaporizing oil an
extinguisher that can be used by hand when required, and also to render the
extinguisher self-acting in the event of a lighted lamp being accidentally overthrown.
An extinguisher made in accordance with this invention consists in attaching to or
fixing round the wick tube or holder of a lamp a vertical slide or casing of any shapo
to suit the wick tube or holder.
To one side of the vertical slide is attached a swivel shutter or extinguisher (the
size and form depending upon the dimensions of the slide). The swivel shutter or
extinguisher is hung from centres or journals about mid-distance of its depth in
suitable holes or bearings in the sides of the sliding case. When the lamp is lighted the
extinguisher is in a vertical position against the side of the wick tube or holder, its
top odgu being a little below the top of the holder. To the bottom of the extinguisher
is attached a fine flexible wire or chain which rises to the top part of the metal
bonnet or cap surrounding the burner, thence passing externally through a hole in the
bonnet or cap made for the purpose, or the chain or wire can be attached to a short
lever of any required form working upon centres through a fine slot in the side of the
bonnet or cap the external length of the chain or wire decending down the side of
the lamp to any required distance. To the end of this chain or wire is attached a
metal weight sufficiently heavy when held in suspension to raise the sliding casing
with its swivel shutter or extinguisher from the bottom of the wick holder to a position
above the top of the wick. At any convenient and suitable part of the baseinent or
framework of the lamp there is formed a projection or stand upon which the weight
is held or carried when in a neutral position and the lamp lighted for use. In this
position the chain or wire connecting the extinguisher with the weight is quite slack,
so that the extinguisher is not influenced by it. To extinguish by hand a lighted
lamp it is only necessary to pull down the chain or wire on the outside. The action
of drawing down the chain or wire will raise the slide and swivel shutter or extinguisher
to a height where the swivelling extinguisher is released from contact with the side of
the wick holder causing it to tilt over the burning wick and instantly excluding the
air necessary for combustion puts out the flame of the lamp. In the event of a lamp
being capsized or over-thrown in any direction the weight is instantaneously displaced

page_text: from its position on the projection or stand, being thus suddenly released it is thrown
in suspension thereby acting with great velocity through the connecting chain or wire
upon the slide and swivelling extinguisher instantly putting out the flame of the lamp
precisely as when used by hand.
To restore and relight a lamp it is only necessary to place the weight upon the stand
used for its reception and lower by means of the chain or wire the slide and extinguisher
to the bottom of the wick tube or holder.
In the drawings Figure 1 is a side elevation of an ordinary oil lamp, the extinguisher,
wire, chain, and weight being shewn in position on a lighted lamp, and by means of
dotted lines the position of the various parts are shewn after they have been brought
into action and the flame of a lamp extinguished. Figure 2 is a front elevation of
the upper portion of a similar lamp shewing the position of the extinguisher with a
light burning.
Figure 3 is a similar elevation showing the position of the extinguisher after use,
and the flame extinguished. Figure 4 is a plan of the lamp gallery and burner
with the slide extinguisher in position and the lamp lighted. Similar letters of
reference indicate corresponding parts.
In Figures 1, 2, 3, 4, A indicates the body of the slide which is a plate of metal
made to the form of the burner tube having freedom to slide up and down it with a
force if necessary not greater than its own weight. B is a swivol valve or shutter
called an
extinguisher" and works from pins, journals, or centres fit mid-
distance of its depth into holes or bearings in the sides of the slide giving the
extinguisher liberty to swing or swivel in the direction required. C is the wire or
chain connecting the swivel extinguisher B to the weight D. E figure 1 is a pro-
jection or holder for carrying the weight D when the lamp is lighted for use.
F figure 3 is an elevation of a burner and the extinguisher in position after having
put out the flame of a lamp.
Modifications in the form of the slide and extinguisher may be made without departing
from the spirit and intention of this invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim as new and novel in connection with oil burning lamps is :—
A combined sliding and swinging extinguisher actuated by an external weight in
suspension, so arranged that the extinguisher may be worked by hand or rendered
self acting by the sudden displacement of the dead weight from its bearing or neutral
resting place on the lamp, the parts being arranged and combined as described and
illustrated in figures 1 to 4 both inclusive of the accompanying drawings.
