PROVISIONAL SPECIFICATION.
Improved Safety Ball Valve Oil Lamp.
I SAMUEL RUSSELL, of 44 Vincent Street, Balsall Heath, in the City of
Birmingham, and County of Warwick, Brassfounder do hereby declare the nature
of this invention to be as follows:-
My invention relates to oil lamps of all classes, and consists of a burner constructed
of two cylinders, one enclosed within the other, composed of brass, copper, or any
other suitable metal or composition, and of other attachments as herein described.
The inner cylinder is fitted with a screwed plug at one end, through the centre of
which a hole is bored, to admit of illuminating oil, in the manner hereinafter
described, this plug, is permanently. fixed to the aforesaid cylinder, leaving the
screwed portion of same projecting therefrom for the purpose herein set forth, and
at the other end of this cylinder, is fixed a collar, projecting over the periphery of
the inner cylinder, to which it is attached & of such convenient shape & dimensions
to cover closely the periphery of the outer cylinder for the purpose hereinafter
described. The inside of this collar is tapped for the purpose of receiving the top
part of the burner to which the lamp glass or globe is arranged in the usual way.
The outer cylinder is constructed with a conical shaped end, and is tapped to receive
a tube which leads direct to an oil vessel of proper size, and which may be
constructed of any convenient metal and arranged on the principle of a chandelier,
or adapted for table lamps, hand lamps, and all other similar contrivances, and will
always be constructed so that this vessel will be higher up in position than the top
of the burner so that the contents will, by gravitation, flow to the inner cylinder as
hereinafter described.
Having placed the inner cylinder inside the outer one, the tapped lug before
mentioned is screwed into the bottom part of the outer cylinder, which is tapped to
receive it, as also the tube leading to the oil vessel, & a metal ball is then placed
inside the space between the screwed lug on the inner cylinder and the top part of the
tube leading to the oil vessel-to serve the purpose of a valve. It will thus be seen,
that the oil, in endeavouring to reach its own level, will force the ball up from the
seat made for same on the tube before mentioned, & so allow the oil to enter the
interior chamber which contains the wick duly arranged in the top of the burner.
To stop the flow of oil and put out the light, it is only necessary to stop the flow of
oil by screwing down the inner cylinder on to the ball by the aid of the collar
projecting over the outer cylinder, the same being provided with a catch for that
purpose, & also so jointed & arranged with a stop fixed on the outer cylinder, to
prevent its being entirely removed from same. I utilise the space between the two
cylinders by filling same with water & so connect the top of the burner with it, so
that should the lamp be knocked over or dropped in the case of hand or table lamps,
the water would instantly put out the light, and thus prevent an explosion.
My invention is intended to be capable of numerous modes of arrangement
without departing from the principle of the foregoing improvements.

I, SAMUEL RUSSELL, of 44 Vincent Street, Balsall Heath, in the City of
Birmingham, and County of Warwick, Brassfounder, 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 :-
My invention relates to oil lamps of all classes, and consists of a lamp constructed
of two cylinders, one enclosed within the other, composed of brass, copper, or any
other suitable metal or composition and of other attachments as herein described.
'
The inner cylinder is fitted with a screwed plug at one end, through the centre
of which a hole is bored to admit of illuminating oil in the manner hereinafter
described; this plug is permanently fixed to the aforesaid cylinder, leaving the
screwed portion of same projecting therefrom for the purpose herein set forth,
and at the other end of this cylinder is fixed a collar projecting over the periphery
of the inner cylinder to which it is attached & of such convenient shape and
dimensions to cover closely the periphery of the outer cylinder for the purpose
hereinafter described. The inside of this collar is tapped for the purpose of
receiving the top part of the "burner" to which the lamp glass or globe is arranged
in the usual way.
The outer cylinder is constructed with a conical shaped end, and is tapped to
receive a tube which leads direct to an oil vessel of proper size, and which may be
constructed of any convenient metal, and arranged on the principle of a chandelier
or adapted for table lamps, hand lamps and all other similar contrivances, and will
always be constructed so that this vessel will be higher up in position than the
entrance for oil to the inner cylinder, so that the contents will by-gravitation-flow
to the inner cylinder as hereinafter described. Having placed the inner cylinder
inside the outer one the screwed plug before mentioned is screwed into the bottom
part of the outer cylinder which is tapped to receive it, as also the tube leading to
the oil vessel; and a metal ball is then placed inside the space between the screwed
lug on the inner cylinder and the top part of the tube leading to the oil-vessel to
serve the purpose of a valve.
It will thus be seen; that the oil, in endeavouring to reach its own level, will
force the ball up from the seat made for same on the tube before mentioned; & so
allow the oil to enter the interior chamber which contains the wick duly arranged
in the top of the burner.
"
To stop the flow of oil and put out the light it is only necessary to stop the flow
of the oil by screwing down the inner cylinder on to the ball by the aid of the
collar projecting over the outer cylinder the same being provided with a
"catch
or milled edge for that purpose, and also so jointed & arranged with a "stop" fixed
on the outer cylinder to prevent its being entirely removed from same: (This stop
arrangement is not shewn in the drawings as it does not form any part of the
novelty of this invention.)
This invention is intended to be capable of numerous modes of arrangement
without departing from the principle of the foregoing improvements.
In order that this invention may be more clearly defined and understood reference
.should be made to the drawings forming part of this Specification and the following
description of same:
Fig. 1 shews the whole invention as applied to the principle of a "chandelier"
shewurhalf in section and half in elevation, a. being the outer cylinder and b. the
inner one with the screwed plug at the bottom of same bored to admit oil,
& shewing the collar c projecting over the outer cylinder a and carrying the top
part of burner p upon which the lamp glass u is arranged. The dotted lines
indicate the level of the oil when the lamp is properly filled-which operation is

page_text: h
accomplished by lifting the cover upwards from the oil vessel g & pouring the oil
into that vessel.
When the inner cylinder is screwed round by the aid of the milled edge thereon.
so that the screwed plug does not press upon the ball f as shewn in the sectional
portion of this figure, the oil contained in the vessel g will flow through the
apertures & through the hollow tubes e and past the ball f & so on into the
chamber b in the direction indicated by the arrows shewn until the level of the oil.
therein is the same as that in the vessel g. Then, the lamp-(which is rendered.
complete by a wick of cotton q & being articulated with a screw or ratchet o in the
top portion p for the purpose of raising or lowering same) may be ignited and the
glass u may be adjusted in position, and as the oil is consumed it will keep on-
flowing as in the aforesaid manner as long as the supply is duly maintained.
The tubular column i can be raised or lowered by this arrangement, viz. :-the
pulley wheels 1. l. which are attached to another tubular column j & the weights n. n..
being attached to the cords or chains m. m. which work over the pulleys l. 1. &
serving the purpose of counterbalancing the tubular column i to which the other
portions of the lamp are fixed as shewn. The upper extremity of the tube ; is.
intended to be fixed to a ceiling or other convenient & suitable place.
Fig. 2. is an enlarged view in section of the burner chambers on Figure 1. and
shews the inner cylinder b screwed down upon the ball valve and the extremity
of the tube e which screws into the conical shaped arrangement d: thus shewing
the lamp with the valve closed.
Fig. 3. shews the principle of this invention applied to a table lamp; in this.
case the oil is admitted to the oil vessel g by means of an aperture in the top part
of same indicated in the drawing at the letter z. This aperture may be covered by
a plug containing a hole through same to admit the atmosphere into the chamber g.
The oil flows from this chamber to the chamber b in a similar method to that.
described in Fig. 1, and the valve is shewn open in this figure as in the said
Fig. 1. The chambers a in this figure & in Figs. 1 & 2. may be if desired employed
to contain water or some other more efficient fire extinguishing fluid, so that should
the lamp become upset such fluid would escape from the chamber a through the
perforations & so have a tendency to extinguish the light.
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 :-
In oil lamps the employment of an oil vessel connected with two chambers,
within such oil vessel, or connected thereto by a hollow tube or tubes to admit of
oil passing through same, and having a metal ball arranged as a valve therein,
actuated by the inner vessel being screwed down upon or off such ball valve
substantially as herein set forth.
