PROVISIONAL SPECIFICATION.
Improvements in Oil Lamps.
I, CHARLES HIDE of No. 2 Highton Terrace St. Elizabeth Road Worthing in
the County of Sussex Architect and Surveyor do hereby declare the nature of
this invention to be as follows:-
That this present application is a modified arrangement of certain parts of a
mechanical device described in my Specification filed June 4th 1892 No. 10,641 as
"An improved means of automatically extinguishing Argand oil lamps, that is to
say lamps burning paraffin and other oils having a circular wick and a central air
tube and also improved means for extinguishing such lamps at will whether used
either as hanging or table lamps." and also a simplification for constructing and
applying the same to the various kinds of lamps hereabove mentioned.
The accompanying drawing is intended to shew a section of this improved
apparatus seated within the central air tube of the lamp, and as regards which it is
distinct, thus enabling the user to add it to the lamp without any difficulty, or
withdraw it from same, when desired.
EXPLANATION OF PARTS AS SHEWN ON THE DRAWING No. 1 FIG. 1.
A denotes the air space within the central air tube of lamp (which tube is
identical with the inner casing of the lamp wick).
B denotes the air space at the bottom of the lamp.
C denotes the plane of the bottom of the lamp when resting on a table or other
flat surface.
D denotes the lamp wick enclosed with, in the inner and outer tubes or casings
which form a part of the lamp.
E denotes the central rod of the extinguishing apparatus with screwed ends to
top and bottom, a cleat soldered on same at F and a slight sinking made round the
same at G.
I denotes the cleat soldered on the central rod E to form an abutment, against
which the spring presses when operating.
G denotes the slight sinking made round the central rod E, this is intended to
receive the upper curved ends of the 3 springs 1. attached to fitting J as hereafter
described.
I denotes the steel spring which operates the central rod E which when
compressed presses against the cleat F. soldered on saine and the under surface of
the guide K.
I denotes 3 small springs with curved tops fixed in the fitting J at equal
distances from each other so as to grasp the central rod E.

page_text: ALTERNATIVE METHOD No. 3 DESCRIBED.
This one can also be constructed much the same as No. 1 alternative method
(described above) the only difference is that instead of having 2 wheels working
together with levers attached this one is operated by one wheel pivoted to frame-
work of cradle and acting upon 2 racks the motion of each is contrary the one to
the other. One rack is attached to the sliding weight and the other to the
extinguishing dise. When one rises the other falls and vice versa. When the
lamp is overturned the action would be precisely the same in this case as in those
already mentioned,
ALTERNATIVE METHOn No. 4 DESCRIBED.
This may also be done by substituting an arrangement of compound levers
working each other in different directions pivoted to the cradle fitted to the central
air tube one attached similarly to the sliding weight and the other to the
extinguishing disc constructed substantially in a similar way as before mentioned.
The action of this mechanism would be precisely the same as those already
described whenever the lamp is overturned.

Improvements in Oil Lamps.
1 CHARLES HIDs of No. 2 Highton Terrace St. Elizabeth Road Worthing
in the County of Sussex Architect and Surveyor 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:-
That this present application is a modified arrangement of certain parts of a
mechanical device described in my Specification filed June 4th 1892 No. 10641
entitled "An improved means of automatically extinguishing Argand oil lamps,
that is to say lamps burning paraffin and other oils, having a circular wick and
a central air tube and also improved means for extinguishing such lamps at will,
whether used either as hanging or table lamps."
The drawing accompanying the Provisional Specification is to be taken as
sufficiently explanatory of this my invention and all reference made to a drawing
is directed to such for purposes of this Complete Specification.
Explantion of parts relating to this my invention, as shown on drawing,
(together with other details connected with the same) which are expressed and
delineated thereon thus

as to grasp the central rod E and to hold it in the desired position when the lamp
is standing erect.
denotes a small metal fitting or ferrule with hole in centre made to receive the
spring and to which the lower ends of the wires L are attached.
K denotes a similar metal fitting or ferrule with hole in centre made to receive
the upper ends of the wires L and to which they are attached.
1. denotes the 3 wires fixed to the ferrules J & K by means of which the
apparatus is held in proper position within the air space A.
M denotes a small metal fitting holed in the centre to allow the rod E to pass
through it. To the upper part of which a piece of brass tube is attached. The
lower or under part of same is furnished with an annular or circular grove made
so as to overlap the tops of the springs forming part of the fitting 1
N denotes a small piece of brass tubing attached to the top of the fitting M, the
upper end has a small ring attached to it to form a stop.

P denotes a weight fitting loosely over the tube N and sliding freely up or
down between the parts denoted by the letters M & O.
Qdenotes small nut screwed on the central rod E to form rest for the parts
denoted by the letters R. S. & T.
R denotes the perforated cap or tube attached to the chanelled extinguisher
which slides up and down the central air tube.
S denotes the lower portion of the brass extinguishing disc (if made in two
parts).
T denotes the upper portion of the brass extinguishing disc (if made in two
parts). This part is, the extinguishing disc 1 also propose to make in one
piece.
U denotes the nut by which the perforated cap and the chanelled extinguishing
disc above mentioned are attached to the central rod E.
V denotes a small fitting attached to the bottom of the central rod E by which
the same may be raised or lowered.
This invention is applicable to lamps burning paraffin and other oils having a
central air tube. In this case the automatic extinguishing apparatus is made
independent of the lamp and can be applied or withdrawn at pleasure. No
alteration in the construction of the lamp is necessary to be made in order to
enable it to be used.
A portion of the extinguishing apparatus used in the construction of this
particular invention is substantially the same as that already described in my
previous Specification eis. No. 10,641 filed June 4th 1892 and may be taken in this
instance to be represented by the several parts denoted on the drawing herebefore
referred to as denoted by the letters E. F. H. Q. R. S. T & U. This invention
consists of a frame work formed of three bent wires denoted on drawing by the
Jetter placed equidistant from each other and secured in the desired position
both at the top and bottom by the ferrules or fittings denoted on the same drawing
respectively by the letters K & J. This is made so as to fit tightly within the
central air tube of iamp, in order to adjust it to the proper height a piece of bent
wire is soldered on the lower fitting or ferrule J projecting outwards and resting
upon the under side of the container of the lamp. The lower fitting or ferrule J
is fitted with a steel ferrule spring denoted by the letter I on drawing designed to
grasp within the 3 springs formed on same, the rod E of the extinguishing
apparatus. The rod E slides freely up and down through holes made for it in the
fittings K&J. There is a small grove or sinking denoted by the letter G on the
lower portion of the said rod E by means of which when the ends of the steel
spring come in contact with it the rod E is held in position. F is a small cleat
soldered on the rod E which acts as an abutment against which the steel spring H
works. The fitting M is groved on the under part as shewn on drawing this is

page_text: furnished with a metal tube N with a slop end over which the metal weight. P
slides freely up and down this combined fitting slides freely up and down the
central rod E. The action of this combined fitting when resting upon the tops
of the 3 springs I (when the lamp is placed upright) is that it presses them inwards
and holds them there whenever the central rod E is placed in the position that
the ends of the springs 1 enter the grove G. The rod is locked in that position
and remains so until it is lifted off or tilted on one side so that the pressure
resulting from gravitation is removed or lessened to the necessary degree. When
this is done the spring denoted by the letter H acting against the fitting K on
the one side and the fitting F fixed to the central rod E on the other expands and
forces the same forwards by means of which the extinguisher (represented by the
parts denoted by the letters Q R S T & U) is brought down upon the tubes or
casings enclosing the wick D and extinguishes the flame. This apparatus can be
arranged so that it may be inserted in the central air tube either from the top or
bottom of lamp, if inserted from the bottom the adjusting piece is made rigid, if
inserted from the top the same piece is made with a spring.

The action of the above mentioned part of the apparatus (composed of the
parts denoted on the drawing by the letters M N O P whose office is to govern
the action of the extinguishing apparatus has been shown above in part. My
reason for using a sliding weight on the tube N is this, when the lamp is upset
the weight is thrown forwards by gravitation and strikes against the stop
fixed on the fittings composed of the parts denoted on drawing by the
letters M. N the force of the impact of the same weight against the stop O
releases the ends of the springs hitherto locked in position in the grove made
for them in the fitting M. This being done the expansion of the spring H
working between the parts F & K ensures the effective working of the
extinguisher portion of the apparatus.
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
An automatic extinguisher for an Argand central draft oil lamp, comprising
a triple pointed ferrule spring 1 securely attached to mountings J K L holding
within its grasp the central rol E of the extinguishing apparatus as shewn on the
same drawing by the combination of parts and denoted thereon by the letters EFH
Q R S T U & V. The fitting composed of the parts as shewn on the drawing
and denoted thereon by the letters M NO which acts as a kind of hood or
locking apparatus as regards the triple pointed spring I immediately beneath
it & the sliding weight working freely up and down on the tube N of the
hooded fitting above mentioned and operating substantially as described in the
above Specification.
