Improvements in or connected with Lamps for Burning Oil or
Spirit.
1, AUGUST KIESOW of 25 Fore Street Avenue, in the City of London
Lamp Manufacturer do hereby declare the nature of this invention to be as
follows:-
:-
The invention relates to improvements upon an invention in respect of which
provisional protection has been granted to me, and which consists of hermetically
ealing the burner with the container and forming in continuation of the wick tube
and beneath the same but preferably of greater area than the wick tube proper.
a wick case of waved form which extends to or near to the bottom of the
container.
This case in a flat wick burner is formed in transverse section of oblong
rectangular form, and instead of being straight or approximately so it is formed
more or less of a regular or irregular waved, corrugated, or S shape in the
direction of its length.
It has however been found by experiment that in consequence of the wick
coming into contact with the wick case at the bends of the S and being more or
less strained around such bends the capillary action of the wick with relation to
the oil is more or less impeded by the large surface contact of the wick case with
the wick and by the exclusion of air from the wick at those points and the result
of this is that the flow of oil to the flame is not sufficiently rapid to give the best
results in the burning of the lamp.
Now the object of the present invention is to obviate the defect above
pointed out.
For this purpose the waved or S shaped wick case is at its sides formed, waved,
corrugated, or fluted.
The corrugations or the like may run in the direction of the length of the wick
case or transversely thereof or diagonally with relation thereto and they may either
be straight or waved, and they may be continuous or broken.
Or in lieu of corrugations or flutings a number of conical or rounded studs or
projections may be employed upon the interior of the wick case.
The corrugations, flutings, or projections, are so formed upon the interior of the
wick case as to offer a very small surface to the contained wick and thus the surface
contact of the wick with the wick case, and more especially at the bends is not
sufficient to impede the capillary action of the wick but the corrugations or pro-
jections permit a flow of air and oil along the wick, and the supply of oil to the
flame is thus rendered sufficient to give the best results in the burning of the
lamp.

Improvements in or connected with Lamps for Burning Oil or
Spirit.
I, AUGUST KIESOW of 25 Fore Street Avenue in the City of London Lamp
Manufacturer 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 :-
The invention relates to improvements upon an invention in respect of which
provisional protection has been granted to me dated the 13th day of September 1894
No. 17449 and which consists of hermetically sealing the burner with the container
and forming in continuation of the wick tube and beneath the same but preferably
of greater area than the wick tube proper, a wick case of S or waved form which
extends to or near to the bottom of the container.
This case in a flat wick burner is formed in transverse section of oblong
rectangular form, and instead of being straight or approximately so, it is formed
more or less of a regular or irregular waved, corrugated or S shape in the
direction of its length.
It has however been found by experiment that in consequence of the wick
coming into contact with the wick case at the bends of the S and being more or
less strained around such bends the capillary action of the wick with relation to
the oil is more or less impeded by the large surface contact of the wick case with
the wick and by the exclusion of air from the wick at those points and the result
of this is that the flow of oil to the flame is not sufficiently rapid to give the best
results in the burning of the lamp.
Now the object of the present
pointed out.
invention is to obviate the defect above
For this purpose the waved or S shaped wick case is at its sides formed waved,
corrugated, or fluted.
The corrugations or the like may run in the direction of the length of the wick
case or transversely thereof or diagonally with relation thereto, and they may either
be straight or waved, and they may be continuous or broken.
Or in lieu of corrugations or flutings, a number of conical or rounded studs or
projections may be employed upon the interior of the wick case.
The corrugations, flutings, or projections are so formed upon the interior of the
wick case as to offer a very small surface to the contained wick, and thus the
surface contact of the wick with the wick case, and more especially at the bends, is
not sufficient to impede the capillary action of the wick, but the corrugations or
projections permit a flow of air and oil along the wick, and the supply of oil to the
flame is thus rendered sufficient to give the best results in the burning of the
lamp.
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an end elevation partly in section representing a lamp having the
present invention applied thereto.
Figure 2 is a vertical section of the burner and wick case separately.
Figure 3 is a similar view to Figure 2 but taken at right angles thereto.
Figure 4 is an underside view thereof.
Figure 5 is a horizontal section taken on the line 1-1 of Figure 2.

page_text: Figure 6 is an elevation representing portions of the burner and burner fitting
and illustrating the method of connecting the burner with the container.
Figure 7 is a plan of the burner fitting separately.
Figure 8 is an elevation partly in section representing. a. modified form of wick
case.
Figure 9 is a side elevation thereof partly in section.
Figure 10 is a vertical transverse section of a portion of a wick case representing
a further modification, and
Figure 11 is a side elevation thereof partly in section.
Figure 12 is a side elevation of a portion of a wick case representing a further
slight modification.
Figure 13 is a vertical transverse section of a portion of a wick case representing.
a further slight modification, and
Figure 14 is a side elevation thereof.
Figure 15 is an elevation of a round wick spirit or benzoline burner having the
present invention applied thereto and
Figure 16 is a horizontal section taken on the line 2-2 of Figure 15.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 7 a represents the oil container or reservoir which is
formed oblong in the manner and for the purpose described in the Specification of
the hereinbefore recited application for Letters Patent, a represents the burner
fitting which is fixed with the container a, and b represents the burner which may
be constructed in any well known manner so as to make an hermetically tight
joint or approximately so with the reservoir or container a.
In the present example this joint consists of a ring or flange 61 upon the burner
provided with clips &* which are adapted to pass through corresponding notches
or openings a formed in the ring or flange a of the burner fitting and to take
under such flanges whilst a** represent stops which engage the clips 61* and
thus ensure the burner occupying the required definite position with relation to the
reservoir a.
c represents the wick and 2 represents the ordinary wick tube enclosing the
same and in continuation of the wick tube beneath the same and fixed with
the burner but preferably of greater area in section than the wick tube 62 is
arranged a wick case 3 of waved form which extends near to the bottom of the
container a and the action of which device is fully described in a complete
Specification filed in pursuance of the hereinbefore recited application for Letters
Patent.
According to the present invention the waved or S shaped wick case 6³ is at its
sides formed fluted in the direction of its length as will be seen more particularly
upon reference to Figures 4 and 5, or it might be waved or corrugated.
The flutings or corrugations are so formed upon the interior of the wick case ³
as to constitute projections 3* which have for their object to hold the wick e off
the general surface of the wick case 63 for the purpose hereinafter more fully
referred to.
In the example given at Figures 8 and 9 the flutings are formed in the sides of
the wick case a transversely thereof, whilst in the example given at Figures 10
and 11 the flutings are formed vertically of the wick case but broken or irregular,
that is to say they are only formed at intervals therein.
In the example given at Figure 12, the flutings are formed diagonally of the
wick case, whilst in the example given at Figures 13 and 14 the sides of
the wick case are formed with a number of internally projecting conical or they
might be rounded studs or projections.
In the example given at Figures 15 and 16 a round wick benzoline or spirit
burner is shown fitted with a wick case b³ formed with longitudinal flutings similar
to those herein before shown and described with respect to Figures 1 to 7.
The corrugations, flutings, or projections are so formed upon the interior of the
wick case as to offer a very small surface to the contained wick c and thus

page_text: the surface contact of the wick c with the wick case 63 and more especially at the
bends is not sufficient to impede the capillary action of the wick, but the flutings
corrugations or projections permit a flow of air and oil along the wick c and the
supply of oil to the flame is thus rendered sufficient to give the best results in
the burning of the lamp.
It will be evident that the form of the projections upon the interior of the wick
case may be varied according to circumstances without departing from the spirit
of the present invention.
Although the invention is primarily intended to be employed in connection with
a wick case formed with two or more bends in the length thereof it will be evident
that it may be usefully employed in connection with a wick case formed with only
one bend.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In combination with a lamp or lamp burner, a wick case of bent, waved,
corrugated, or S shape descending into the reservoir or container, and upon its
interior formed with continuous or broken corrugations, flutings, or projections,
substantially as herein shown and described and for the purpose stated.
Dated this 20th day of March 1895.
