PROVISIONAL SPECIFICATION.
Improvements in and connected with Lamps for Burning Light or
Heavy Oils.
I, GEORGE WHITE, of 26, Colebrook Row, London, E.C., Doctor of Medicine,
do hereby declare the nature of this invention to be as follows:---
According to this invention the oil reservoir is formed with a central well or
depression. Passing centrally through the reservoir is a vertical tube open at
top and bottom. On the outside of this tube is fitted the wick tube, which con-
sists of two half circles extending down to near the well, consequently each of
the two wicks are held in a half circle. The wicks are raised and lowered by
spur wheels connected to the wick tubes projecting through slits. These spur
wheels if arranged within the reservoir would be actuated by outside wheel
operating mitre gearing within the reservoir. The burner only consists of the
cone which is made with openings to suit the circular wicks, air inlet openings
and the gallery to support chimney and globe; and instead of screwing into the
top of reservoir as is usual, it slides on the part of the wick tube which pro-
jects beyond the top of reservoir.
By the above arrangement an improved supply of air is conducted up the
central tube to the wicks.

Improvements in and connected with Lamps for Burning Light or
Heavy Oils.
I, GEORGE WHYTE, of 26, Colebrook Row, Islington, Dr. of Medicine, 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:
This invention relates to improvements in and connected with lamps for burn-
ing light and heavy oils and has for its object to provide a lamp having a con-
tral air draught, wherein the wick can be more easily adjusted and an improved
supply of air conducted to the burner. And in order that this my said invention
may be the more readily understood and carried into practical effect reference is
hereby made to the accompanying sheet of illustrative drawings wherein :—
Fig. 1 represents in sectional elevation a lamp reservoir and burner con-
structed in accordance with my invention.

page_text: Fig. 2 being a sectional plan thereof on line X-X while,
Figs. 3, 4, 5, 5 & 6 are views explanatory of details of my invention.
Referring to these drawings wherein like letters of reference indicate corres-
ponding parts throughout all the figures, a represents a lamp reservoir, being
preferably constructed with a central well or depression a¹.
Passing centrally through this reservoir a I provide a cylindrical air tube b
which air tube b is attached at or near its lower end b¹ to the lower part a
of the reservoir a and extends upwardly to a convenient distance above the said
reservoir. Surrounding this air tube 6 I arrange two approximately semi-
circular sleeves or cases c & c which sleeves or cases surround nearly the whole
of the air tube b above the reservoir a and extend downwardly a convenient
distance within such reservoir, being attached thereto at . Within these
sleeves or cases I arrange two independent wicks d & d' each of which is cap-
_able of independent adjustment longitudinally by means of one or other of the
pairs of toothed wheels or d operating through apertures in the sleeve cas-
ing which pairs of wheels are each separately actuated by means of milled
nuts (Fig. 6) arranged on the top of the reservoir d. These milled nuts d'
are attached to the tops of spindles which spindles are held in position by
means of the tubular brackets de depending from the top of the reservoir a
within such reservoir. The lower ends of these spindles are provided with
bevel wheels which gear with other bevel wheels fastened on the ends
of the suitably journalled spindles d carrying the afore mentioned pairs of
toothed wheels and d. It will be easily seen that by this means each of the
halves d or d of the complete wick dd can be adjusted independently, thus
ensuring greater regularity of flame. Arranged to slide longitudinally along a
convenient portion of the air tube 6 and wick sleeves or cases c & above the
reservoir a an extinguisher may be provided such extinguisher consisting of
two tubes e & e arranged one within the other and connected together at the
top by an approximately rectangular plate e thus providing an annular space e
to contain the upper part of the air tube 6 and wick sleeves or cases c & c¹.
The rectangular plate e fits into slots in the top of the air tube b, such slots
being arranged at the spaces (see Fig. 2) between the wick case c & e, thus
ensuring the correct position of the joining plate between the said wick
sleeves or cases & c. A portion of the lower part of the outer surface of the
outer tube e may be provided with a rack f in which works a pinion fl and
in operation when it is desired to put out the light the pinion would be turned
so as to raise the extinguisher till it reaches the under surface of the flame
spreading portion g¹ of the burner cone 9 (as shown in dotted lines in Fig. 1)
when all air being excluded from the wicks the lamp would be extinguished.
The burner cone g aforesaid of the burner is formed in two parts the flame spread-
ing portion of which is arranged to fit on the main portion g thereof. Aper-
tures 9 & 9 are provided in the said flame-spreading portion g' for the flames
of the two semi-circular wicks to pass through. This cap 9 is arranged to slide
within the gallery which carries the lamp glass while this gallery h is in
its turn arranged to slide outside the wick sleeves or cases c & c¹ and support
itself on the top of the reservoir d. A gallery for supporting a globe may be
attached to the aforesaid gallery in the usual manner.
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:-
1st. The improvement in or connected with lamps for burning light and heavy
oils consisting in providing around a convenient portion of a central air draught
tube passing through the lamp two approximately semi-circular sleeves or cases
each arranged to contain an independently adjustable wick each wick constitut-
ing half the entire circular wick substantially as hereinbefore described and
illustrated.

page_text: 2nd. In means for adjusting the wick of a lamp the combination of a milled
nut arranged on the top of a lamp reservoir with a spindle passing through a
tubular depending bracket within such lamp reservoir such spindle terminating
in a bevel or mitre wheel gearing with another bevel or mitre wheel on the
spindle arranged in suitable bearings and carrying a pair of toothed wheels each
operating through an aperture in the wick sleeve or case all arranged combined
and operating substantially as hereinbefore described and illustrated.
3rd. The improvements in lamps for burning light and heavy oils consisting
in the particular construction, combination and arrangement of the various parts
substantially as hereinbefore described and shewn.
