Improvements in Lamps for Burning Candles, Mineral and
other Oils.
I JOSEPH RAYNER MA. Colliery Underviewer New Sharlston W Wakefield in
the County of York, do hereby declare the nature of my invention for IMPROVE-
MENTS IN LAMPS FOR BURNING CANDLES MINERAL AND OTHER OILS to be as
follows
-
'
I make the perforations through which the air passes to feed the flame at the
bottom of the glass chimney in rows having spaces betwixt them, I surround them
with a ring of metal or other material having perforations at intervals and fixed
so that the air passing through these perforations has to turn aside to pass into
the lamp and in experiencing strong currents of air the excess passes out of the
perforations on the opposite side of the lamp, I also effect this by making the
perforations of what is usually termed the burner below the perforations of
the outer ring, I place over the outer ring a ring with corresponding perforations
having a non-conducting button by which I tuin the ring and close the ventilator,
In some cases I make a corresponding-arrangement at the top of the glass or
chimney of glass and metal top, connecting top and bottom ventilators by metal
straps so that the entrance of the air and the exit of the products of combustion
may be arrested simultaneously and the light or inflamed vapour at once
extinguished and the danger incurred by blowing out avoided
In some cases I make the glass chimney slitted so that a cylinder of wire gauze
may enclose it tightly & the front cut away so that the light passes through glass
only and a shield behind protects it from currents of air & it may be used to
examine for escapes of gas in households or other places and a second tube be
twisted round over the gauze to exclude the outer air.

page_text: I JOSEPH RAYNER MA of 11 High Street New Sharlston W. Wakefield, in the
County of York, Underviewer do hereby declare the nature of my invention for
IMPROVEMENTS IN LAMPS, FOR BURNING CANDLES MINERAL 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.
--
I make the perforations through which the air passes to feed the flame at the
bottom of the glass chimney in rows having blank spaces betwixt them.
I surround this arrangement with a ring of metal or other material having
perforations at intervals and fixed so that the air passing through these
perforations has to turn aside to pass into the lamp and in experiencing strong
currents of air the excess passes out of the perforations on the opposite side of the
Lamp, I also effect this by making the perforations of what is usually termed the
burner below the perforations of the outer ring-I place over the outer ring a ring
with corresponding perforations, having a non-conducting button by which I turn
the ring and close the ventilator-In some cases I make a corresponding arrange-
ment at the top of the glass or chimney of glass and metal top, connecting top and
bottom ventilators by metal straps so that the entrance of the air and the exit of
the products of combustion may be arrested amultaneously and the light or
inflamed vapour at once extinguished, and the danger incurred by blowing out or
turning down the wick avoided-In some cases I make the glass chimney slitted
so that a cylinder of wire gauze may enclose it tightly and the front of the gauze
cut away so that the light passes through glass only, with a shield behind to
protect the flame from currents of air-I place around this another cylinder or
slide for turning round the gauze to exclude the outer air-Inside this arrangement
of slitted glass tube with gauze fitting tightly over the slit I put another chimney
of glass around the light and use the lamp for illumination and examination for
escapes of gas in households or other places.
And in order that my invention may be completely understood reference is given
to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation. Fig. 2 a transverse section through centre of lamp and
Fig 3 a sectional plan looking at the top.
a is the oil tank or lamp bottom which is of ordinary construction, b 18 a rằng
perforated at c through which au 18 passed to feed the flame. This is surrounded
at a suitable distance therefrom by a ring d of metal or other material, having
perforations at e in such a position that the air passing through these perforations e
has to turn aside as shown by arrows in order to pass through the perforations c
into the lamp, any excess of air travels round the inner ring b and out at the
perforationd at the onnoate side of ring h

page_text: I fit outside the outer ring d another ring f, having corresponding perforations
or holes g therein. This is provided with a button h by which the ring ƒ may be
moved round and the perforations in the outer ring d closed by covering them with
the blank spaces on the ring f, and so prevent the admission of air to feed the
flame.
In some cases I provide a corresponding arrangement of rings (which I have
marked with corresponding letters) at the top of the glass chimney i and connect
the two by metal straps or pillars 3, so that the inlet of air and exit of products of
combustion may be controlled simultaneously and the light or inflammed vapour at
once extinguished, and the danger incurred by blowing out the flame or turning
down the wick prevented
In some cases I make the glass chimney i slitted so that a cylinder of wire
gauzek may enclose it tightly, and the front of the gauze cut away as shewn
at so that the light passes through glass only. When preferred I place a shield
behind the light and provide any suitable means for turning round the gauze when
required
In order to ensure greater safety when the glass chimney & is alit and when the
lamp is used for illumination in households or other places, and in examinations
for test of gas, I provide another glass chimney within the outer chimney.
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 18.
1 The arrangement of perforated rings b, & and ƒ at the bottom and top of
glass chimney, constructed and operated in the manner described for the admission
and exclusion of air and products of combustion substantially as herein set forth
2nd The slitted or otherwise glass tube surrounded by gauze k, such gauze k
being cut away as shewn at 1 so as not to intercept the light, substantially as
herein set forth
