PROVISIONAL SPECIFICATION.
Improved Oil Heating or Cooking Stove and Steamer.
JOHN HOWARD Ross, 35 Wills Street. Lozells, Birmingham, Lighting
Engineer, do hereby declare the nature of this invention to be as follows:-
My improved stove consists in a suitable oil container having a tube passing
right up through from the bottom, upon which the wick fits, and a tube which
fits over the wick and is secured by a bayonet joint to the reservoir or to a
band or fitting fixed to the reservoir top. Surrounding the wick within the
outside wick tube is a tube or carrier which catches the wick on the outside
and is caused to move up and down within the outer wick tube and carry the
wick with it by means of a cog or pinion engaging with a rack attached thereto.
or part thereof or into perforations, the bars between which may be used for
the teeth of pinion to work on and the said cog or pinion I fix upon a spindle
between brackets having holes or bearings through which this spindle passes and
in which it and the pinion is free to revolve, the bracket or brackets I fix upon the
outer wick tube in such a position that the pinion is half way between the extreines
of the travel of the rack or part it engages with, the spindle may have at one end
n button to operate it with or in cases where the top of wick tube projects above
the top of reservoir so short a distance that the cog or pinion must of necessity be
lower than the top of reservoir 1 employ another spindle fixed at right angles to
the first spindle and having a worm wheel of such a diameter as that when the
spindle is fixed in burner above the level of top of reservoir the thread of worm or
screw will reach down to and engage with the teeth of cog or pinion and revolve
it, the spindle being turned by a button or handle in the usual way.
To secure the outer wick tube to the reservoir I employ a stamping or spinning,
the inner part of which fits and is secured to the outer wick tube whilst the outer
part fits upon a collar or band upon the top of reservoir, this stumping or spinning
is formed as a cap the sides of which are bayonet slotted; fitting over it is a loose
ring having pins projecting from it through the bayonet slots of cap into corre-
sponding bayonet slots in the collar or band of reservoir which secures the cap to
the reservoir by turning the loose ring round to left or right as may be arranged;
other methods of securing it may be employed.
The spindle of worm wheel may also come through this cap and the half or a
portion of worm wheel be within it whilst the other portion reaches down into the
reservoir.
Upon the outer wick tube I fix removeably above the first stamping, a stamping
having the centre drawn or stamped down to fit on outer wick tube, whilst the
upper part is saucer shaped and is formed as a gallery or holder for the chimney
of lamp, round the drawn down part just under the saucer shaped part or part
which carries the chimney I pierce one or more rows of holes to admit air to the
outside of the flame in such a manner as to produce a Hame having a large amount
of blue at its base and ending in perfectly white tips, the spacing of the holes
being regulated so as to divide the flame up into little tails.
When necessary, to
prevent sudden draughts of air from disturbing the flame I place a perforated band
upon the top of the cap which fits over reservoir and between it and the stamping
above it which chimney fits into but with a sufficient air space between this
perforated part and the top stamping to prevent conducted or radiated heat from
the latter reaching the perforated band.

page_text: In the central tube arrange an air deflector formed of a tube flanged in at top,
of smaller diameter than the central wick tube, central therewith is a still smaller
tube which carries and has fitted to it at its top a washer or disc, this disc causes
the air passing up through the central wick tube to be impinged upon the inside of
the flame. These two tubes are held together concentrically within the central
wick tube by means of a number of blades so arranged that when in place the
outer parts fit the central wick tube and having a tongue or tongues projecting
from a step closer to the centre through holes or slits pierced in the outer tube of
deflector, and having their inner ends formed as segments of a circle surrounding
the inner tube which carries the disc or washer, each segment having on its edge a
tongue or tongues projecting through corresponding slits at the angle of the next
with fat portion, and when in position tongues raised from the flat portion of the
blades are forced down and secure the former tongues in position without the use
of solder.
The chimney of Imp I preferably form of metal, taper shape, smaller at the
top and having a hole cut out by tools at one side in such a manner that two sides
of the hole can he raised so that a tale or mics can be sprung under those raised
parts at ench side, whilst at top and bottom it fits over the outside; to prevent the
ialc or mica from being sprung out in cleaning of the chimney, I use strips of
metal placed over and along the top and bottom edges of the tale or mica and
secured by having their ends passed through suitable holes or slits in the chimney
and closed down on the inside.
Where great bent is required, I use a number of these burners upon one
reservoir arranged along side of each other, or I use concentric circles of wicks,
the flanged out portion of the stamping which carries the chimney where only one
wick is used, being so shaped that it acts as a central deflector for the wick which
surrounds it, and so on according to the number of wicks used in this case, each
set of wick tubes is separated one from the other having a large air space between:
the oil being carried from the reservoir to the different wick tubes by means of
small connecting pipes or channels, and the wicks being raised and lowered in a
similar manner to that used in lighthouse burners, which is well understood;
within the central wick tube of each concentric ring of wick tubes which surrounds
ale inner ring of wick tubes I place a tube of smaller diameter than the inner wick
tube of each ring, flanged inwards at the top, which acts in a similar manner to the
outer tube of the central deflector.
Upon a suitable stand, above the chimney of stove, for steaming vegetables
food &c. &c. 1 place a vessel to hold water: over this vessel I place one or more
vessels on top of each other according to the number of articles to be steamed,
these top vessels are preferably formed with vertical sides and have their bottoms
stamped or sloped down so as to form a dish of suitable capacity to contain the
whole of the water condensed from the steam from each article cooked, in the
bottom of each vessel and separate from each other, and from the water in
the bottom vessel, the water in which can be used for any other purpose when the
steaming is finished; in each of the top vo-sels 1 place a grid, perforated plate or
wire basket, upon or in which the food to be cooked rests, this grid, perforated
plate or basket rests upon the top part of the sloped sides of the bottom, and just
under this grid, perforated plate or basket romul the top of the sloped sides of the
bottom pierce sufficient holes to allow the steam from the bottom vessel to pass
in through the steam in bottom vessel passes in through those holes towards the
centre of the bottom of vessel above and is diffused under the bottom of grid,
perforated plate or basket passing up through it and through the food upon the
grid, perforated plate or basket into the vessel above in same manner, and so on
from one vessel to the other until a sufficient number of vessels are placed one above
the other to fully utilise the cooking power of the steam generated.
Dated this Eighteenth day of June 1894.

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:-
In the accompanying drawing which is part shewn in section and part in
elevation
A is the oil reservoir.
B the central wick tube.
Ca tube flanged in at top, fitted into the central wick tube by blades D.
E is the outer wick tube which is soldered or otherwise secured to cap F.
G is a loose ring round cap F having projecting pins to engage with bayonet
slots in the collar of the reservoir.
I is a corrugated tube engaging with toothed wheel J, which is free to revolve
in a bracket fixed to the tube E.
Lis a worm wheel secured to spindle Moperated by knob N, when N is turned
it revolves the spindle M and worm wheel L which engaging with the toothed
wheel J, causes it to revolve, and the toothed wheel J, being in engagement with
the corrugations on tube 1, the tube is consequently moved up or down as
the knob N is turned to the right or left. The tube has inwardly turned
teeth which press into the wick O, causing it to be carried up or down along
with it.
P is a central spreader or air deflector, which impinges the air going up through
the central tube, upon the inside of the flame.
Qis a perforated saucer shaped stamping, the bottom part of which is made to
slide or screw on to the outer wick tube, the upper part carrying the chimney R,-
this stamping is perforated with round holes S, the air passing through which,
splits up the llame into little round tails, causing it to give off great heat. There
are also square or other shaped holes T, for the purpose of balancing the air
draught, and also to supply a larger volume of air to be impinged upon the outside
of the wick and consequently up to the flame. The chimney R is fitted with tale
or mica panes U by having the edges of the opening raised up so as to lap over
the tale. The talc U, after it passes under the raised parts V, above and below
the opening rests upon the outside of the chimney, these ends are securely kept
against the chimney by metal strips passing over them, the ends of which are
passed in through slots or openings in the chimney and bent over so as to secure them
as shewn at W. I Instead of the toothed wheel J, engaging with a corrugated
tube, it may engage with a tube having perforations to receive and engage with the
teeth of the wheel, or it may engage with a rack or other contrivance adapted to
carry the wick.
X is a perforated drum fitted on to the reservoir A for the purpose of carrying
vessels to be heated, it is shewn in the drawing with a special construction of apparatus
for cooking food by steam. In the steaming apparatus shewn A 1. is a metal drum
having a spout A 2. for convenience in filling with water, whilst in use, the dotted line
represents the top of the water. B 1. is a similar drum to A 1. but is fitted with a
hollow pan at bottom B 2. also a band B 3. which fits into the drum A 1; resting
upon the top shoulder of B2. is a perforated grid 134. arranged with suitable
handles to lift it out, upon this grid the food to be steamed is placed. When in
operation, the action is as follows, the water in A 1. is converted into steam by
the beat from the flame of stove, this steam passes through the holes in dish B 2.
and up through the perforated grid B 4. as shewn by the arrows-it then goes up
through the similar parts in C 1. which is fitted on the top of B 1. and so on

page_text: through any number of steamers placed on the top of each other, until the steam is
exhausted. The hollow dishes 13 2. collect the condensed steam from the various
vegetables or foods whilst being cooked, so that the water from the one food or
vegetable cannot drop upon or flavour any other food or vegetable which may be
beneath it.
The stove can be used for heating purposes only, by simply taking off the
steaming apparatus and drum X.
Instead of one circular burner I may use concentric circles of burners, having
the wicks raised and lowered by any well known means, such as is used in
lighthouse burners, which is well understood. Each circle of wick having a
similar arrangement of holes surrounding it to divide the flame as described in Q-
by this arrangement the outer saucer shaped stamping only may be formed to carry
a chimney, the outer edges of the inner saucer shinped stampings being so shaped
as to take the place of a central air deflector, to impinge air upon the inner side of
the flames respectively which surround then.
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 1
claim is :-
:-
1. In an oil stove, the knob N spindle M worm wheel L. and toothed wheel J
arranged with to engage with a corrugated tube, rack or other arrangement for
carrying the wick, substantially as and for the purposes described and illustrated
