Improvements in the Burners, and Accessories to the Burners, of
Stoves and Lamps Burning Mineral or other Oils.
WILLIAM HENRY PARKER Manager 37 Wretham Road Handsworth Bir-
mingham do hereby declare the nature of this invention to be as follows:-
This invention has for its object the isolation of the tube or tubes, containing or
surrounding the wick of oil stoves and lamps, from the flame, in such a manner that
the heat of the flame is prevented from communication with the said tube or tubes,
which contain or surround the wick; the supply of oil to the flame is thereby kept
regular, & does not increase with the length of time the stove or lamp burns; so
that the rising & smoking of the flame is prevented & the oil in the reservoir is
kept cool. My invention consists in the use of a slotted or perforated plate or cap,
situated above the termination of the wick-case or tube so arranged that the air
being drawn in & through the slot or perforation, impinges on the wick, maintains
the flame above the plate or cap, & the current of air passing up between the edges
of the plate or cap & the surface of wick, prevents that portion of the wick
between the flame & the end of the wick-tube, from becoming ignited; so that the
flame is cut off from communication with the wick-case or tube by a strip or band
of unburning wick, maintained in that condition by the current of air passing up
through the slotted plate or perforated cap.
Another mode of effecting this object is to divide the wick-tube so that the heat
is prevented from descending the whole length of the case or tube by the upper
portion of the latter being cut off at any convenient point between the oil vessel
& the flame in such a manner that the communicated heat from the flame cannot
reach the lower part of the burner or wick-tube.
These means of preventing the descent of the heat from the flame to the wick-
tube, wick, & oil may be applied to stoves or lamps with flat or round wicks
burning petroleum or other oils & are specially applicable to flat-wick burners used
in stoves for cooking & heating purposes.

COMPLETE SPECIFICATION.
Improvements in the Burners, and Accessories to the Burners, of
Stoves and Lamps Burning Mineral or other Oils.
I WILLIAM HENRY PARKER of 37 Wretham Road Handsworth Birmingham,
Manager 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 has for its object the better combustion of oil in the burners of
stoves & lamps, & for the isolation of the tube or tubes containing or surrounding
the wick from the flame, in such a manner that the heat of the flame is prevented
from communication to & with the lower parts of the said wick tube & burner.
The method by which I accomplish these objects, is by the use of a slotted plate
or perforated cap situated above the termination of the wick tube (or in some cases
I place it slightly above or below the top of the wick tube) so arranged that the
air being drawn in and through the slot or perforation impinges on the wick at or
about the point of ignition, thus a purer flame & more perfect combustion are
obtained.
The slotted plate may be either of solid metal or of gauze. This plate may be used

page_text: either alone or in conjunction with the ordinary gauze employed to check & distribute
the current of air in ordinary burners, & may be placed either at right angles, at
an acute angle, or at an obtuse angle with the wick tube.
Or the upper part of the wick tube may be cut off, or divided from the lower
part in such a manner that the heat acquired at the top from contact with the
Hame, may not descend to the lower parts of the wick tube or burner.
I will now refer to the accompanying drawings to illustrate my invention. The
similar letters of reference on the various drawings refer to similar parts.
Fig. 1 shows a plan of the plate C. D. with the slot A. B., which must be slightly
larger than the wick, so that the air may pass between its edge & the edge or
surface of the wick, or of the wick tube, if the latter is above the edge of
the slot.
'
Fig. 1 is a view of the same shewing it as a perforated plate.
Fig. 2 shews the plate in position above the end of the wick tube E (shewn in
dotted line) the slot A. B. being situated immediately over the wick, to allow it to
pass through A. B. leaving an equal space on each side, between the wick & the
edge of the slot A. B. In this position (if the slot be not too wide) the flame will
burn only above the plate C. D., being maintained in that position by the current
of air passing up through the slot A. B. The portion of the wick between the
underside of the plate C. D. & the top of the wick tube E does not burn & no heat
is therefore communicated to the wick tube E.
Fig. 3 shows the wick tube divided at F. G. so that any heat acquired by the
part of the wick tube E' from the flame at its summit would be coutined to that
portion of the wick tube above F. G. The upper portion E may be quite
detached from the lower portion of the wick tube & fastened to the ordinary
gauze plate or to some other convenient part of the burner, or it may be partially
connected with Ez by small strips of metal or wires F¹ or by several supports
leaving portions of the wick exposed at intervals.
This form of wick tube may be used either with or without the slotted plate C. D.
A convenient combination of Figs. 2 & 3 is shown at Fig. 4.
In this the division F. G. is made nearly at the top of the wick tube E so that
its upper part E (Fig. 3) becomes strips or wires E³, the slotted plate C. D. (Fig. 2)
coming into position as shown by the line H. K. across the exposed band of wick
which is kept from ignition below H. K by the current of air passing up through
the slot A. B. & between its edge & the surface of the exposed wick. The strips
or wires E³ are either attached to the slotted plate C. D. (as shown in plan &
section Figs. 5 & 5) or may be connected with E Figs. 3 & 4 by small strips of
metal or wires as described in the case of Fig. 3.
I have described & illustrated only a broad wick burner such as is generally used
with stoves & lamps for cooking & heating purposes, but the same principles and
attachments are also applicable to the burners of lamps used for illuminating
purposes.
Fig. 6 shews a cap L M with the centre O pierced out applicable to round wick
burners, N is the tube surrounding the wick, & the cap L M being slightly larger
in diameter than the wick allows the air to pass between its edge & the wick, thus
the flame is maintained above L M as described in the case of the flat wick burner
in Figs. 2 & 4 L M being similar in purpose & taking the place of the slotted
plate C. D., & fitted with side piece L' M to conduct the air to its summit.
The slotted plate or cap may be used as described or it may be used with the
cone or dome usually employed above the wick tubes of ordinary lamp burners.
And it may be used alone to check or guide the air supply, or in addition to the
usual gauze employed in the ordinary form of burner.
Having now particularly described & ascertained the nature of iny said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is :-
(1) The use of a slotted plate or cap so arranged as to cause the air to impinge

page_text: on the wick of the burners of stores & lamps at or about the point of ignition
whether placed at right angles, at an acute angle, or at an obtuse angle with the.
wick tube substantially as herein set forth.
(2) The method of preventing the heat of the flame of flat wick burners from
affecting the lower parts of the burner & wick tube by a band of unignited wick
intervening between the flame & the lower parts of the burner & wick tube,.
whether the said band of wick be totally exposed or only partially so as described
& illustrated in Figs. 3 & 4 & whether used in combination with the slotted
plate C. D. Fig. 1 or without it.
(3) The construction of cap in combination with a tube for conducting the air,.
substantially as illustrated in Fig. 6 & described herein.
Dated this 18th day of March 1892.
