Improvements in or connected with Hydro-carbon Burners.
I 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 in or connected with Hydro-carbon
Burners and has for its objects firstly to construct an Argand burner in such a
manner as to facilitate the insertion of the wick into the wick tube or case and
secondly to provide a safety locking device for preventing the accidental
disconnection of a burner not necessarily an Argand burner from its reservoir or
container.
In Argand burners as generally constructed the outer tube of the wick case is
some little distance from the top divided horizontally and connected by means of a
screw joint so that when it is desired to insert a new wick the detachable part of
the wick case is unscrewed to allow of the wick carriers or claws being raised above
the tube.
This is a troublesome operation and does not remove the claws out of the way of
the wick and the removeable upper part of the tube in time gets out of truth and
prevents the correct trimining of the wick and furthermore by reason of the upper
part of the outer tube being detachable it is impossible to carry the vertical slot or
air opening sufficiently high to ensure the necessary circulation of air to keep the
wick tube cool and the burner was therefore liable to become overheated.
Now according to the first part of my present invention instead of forming the
upper part of the outer tube of the wick case removeable I form such outer tube in
one piece, and I am thus enabled to carry the air slot or opening much higher than
heretofore and generally to obviate the defect above pointed out.
In burners of this character the wick is raised by means of several serrated
projections or claws from a tubular carrier which slides upon the inner tube of the
wick case and has fixed to the lower end thereof a rack which engages a pinion
upon the winder shaft so that as the winder is rotated the tube and claws or
projections are raised or lowered thus carrying the wick with them.
These projections or claws as heretofore arranged upon a carrier tube inseparable
from the burner form a serious element of difficulty in inserting the wick.
Now according to my invention I form the tubular carrier for the claws or wick
raiser removeable that is to say I cause it to fit telescopically upon the inner tube
of the wick case at its lower end, and I split the tubular carrier or form thereon a
long vertical slot open at its upper end, and thus obtain an elastic fit between the
parts, and I guide the tubular carrier in its movements by means of a guide bar or
I might employ guide studs projecting from the inner tube of the wick case at its
lower end and bearing against the edges of the tubular carrier bordering the
vertical slot or opening.
-
In order to detachably connect the lower end of the winder rack with the lower
end of the tubular carrier of the wick raiser and to automatically centralise the
same with relation thereto, I fix upon the lower end of the rack a cone, and I
provide at the lower end of the tubular carrier a circular aperture which receives
the cone so that upon the rack being wound downwards until the cone engages the
aperture of the tubular carrier the parts will be truly centralised.
In order to fix the cone of the rack with the lower end of the tubular carrier, I
form upon the cone studs or projections and in connection therewith I employ an
apertured washer adapted to take a bearing upon the lower end of the carrier, and
slotted to correspond with the studs or projections so that in one position it will

page_text: pass over such studs, and when turned will lock the cone with the tubular wick
carrier.
By this construction I am enabled by simply displacing the washer to remove the
tubular carrier from the inner tube of the burner, thus taking away the claws or
wick raiser and leaving the wick case perfectly open and free for the insertion of
the wick therein, after which the tubular wick carrier may be inserted in position,
so that its claws engage the wick, and fixed with the rack when the burner is ready
for use.
By this arrangement of parts I am enabled to almost instantaneously insert a
wick and that without the necessity for skilled knowledge added to which the wick
raiser in practice raises the wick with greater truth than heretofore, by reason of
the automatic adjustment of the winder rack with the carrier tube.
Referring to the second part of my invention, hydro-carbon burners are
commonly connected with their reservoirs or containers by means of a simple form
of clamping device or joint consisting of two inclined projectious on the collar of
the container which are embraced by corresponding clips upon the burner, so that
upon placing the burner in position and turning it a given distance it will by
reason of the inclines be connected more or less tightly with the collar of the
container.
This is a ready means of connecting a burner with its container, but it possesses
the disadvantage that if the connection is not carefully made, the burner is liable
from vibration or other causes to turn back and become disconnected from the
container the inclines of the clamping device or joint facilitating this action, and
serious accidents have resulted from this cause.
Now according to the second part of my invention I propose by a very simple
and inexpensive device to render such an accident impossible.
For this purpose I provide upon the burner which carries the clips, a locking
device which consists of a plate spring curved to the shape of the burner and
provided with a returned end adapted to engage the broad end of one of the
inclines on the collar or ring of the container, and I fix the opposite end of this
spring to the burner and form in the spring and in the ring of the burner curved
slots through both of which I pass a stud headed at one end and flanged at the
other so that by moving this stud in one or the other direction the returned end of
the spring will be either raised or lowered.

Improvements in or connected with Hydro-carbon Burners.
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 in or connected with Hydro-carbon
Burners and has for its objects firstly to construct an Argand burner in such a
manner as to facilitate the insertion of the wick into the wick tube or case and
secondly to provide a safety locking device for preventing the accidental discon-
nection of a burner not necessarily an Argand burner from its reservoir or
container.
And in order that the said invention may be clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings fully to
-describe the same.

Figures 12 represent a device for rendering the aperture washer or nut
inseparable from the tubular carrier.
Figure 13 is an elevation of parts of the burner and container representing
more particularly the means for locking the burner with the collar or ring of the
container and showing the parts in their locked position.
Figure 14 is a plan thereof.
Figure 15 is a vertical section taken on the line 7-7 of Figure 13.
Figure 16 is a similar view to Figure 13, but representing the parts in their
unlocked position and
Figure 17 is a plan of part thereof.
In the several figures in which like parts are indicated by similar letters of
reference Figures 3 to 11 and 13 to 17 are drawn to an increased scale with respect
to Figures 1, 2, and 12.
Referring to Figures 1 to 12 a represents to container or reservoir, & represents
the body of the burner, c represents the outer tube of the wick case and, d represents
the inner tube thereof.
In Argand burners as generally constructed the outer tube c of the wick case is
some little distance from the top that is to say just below the contracted part thereof
divided horizontally and connected by means of a screw joint or other fastening so
that when it is desired to insert a new wick the detachable part of the wick case c
is removed to allow of the wick carriers or claws such as e¹ being raised above the
tube c and more or less out of the way and the wick which is inserted from the
lower end of the wick case has with considerable trouble to be drawn beyond
the wick raiser or claws e' until the latter engage the wick at the required distance
from the top.
This altogether is a troublesome operation and the reinoval of the upper part of
the outer tube c does not enable the claws to be removed altogether out of the way
of the wick, whilst after a time the removeable upper part of the tube c gets out of
truth and prevents the correct trimming of the wick, and furthermore by reason of
the upper part of the outer tube e being detachable it is impossible to carry the
vertical slot or air way c* sufficiently high to ensure the necessary circulation of
air to keep the wick case. cool, and the burner is therefore liable to become
overheated.
Now according to the first part of the present invention, instead of forming the
upper part of the outer tube of the wick case removeable, such outer tube c is
formed in one piece and it is thus possible to carry the air slot or opening c*
much higher than heretofore and thus to obviate some of the defects above
pointed out.
In burners of the character hereinbefore referred to the wick raiser or claws e
project from a tubular carrier such as which slides upon the inner tube d of
the wick case and has fixed to the lower end thereof a rack which engages.

page_text: pinion upon the winder shaft f2 so that as the winder is rotated the tube e
and claws or projections e¹ are raised or lowered carrying the wick with them.
The carrier tube e together with the projections or claws e as heretofore
arranged were inseparable from the inner tube d of the wick case and they formed
a serious element of difficulty in inserting the wick, as although during that
operation they were raised above the top of the wick case after the removeable
part had been taken off as herein before described they notwithstanding this had a
tendency to catch the wick and prevent it being drawn the proper distance beyond
the claws.
Now according to the present invention the tubular carrier e for the claws or wick
raiser e' is formed removeable from the burner, that is to say it is caused to fit
telescopically upon the inner tube d of the wick case at its lower end whilst it is
split or has formed therein a long vertical slot e² open at its upper end and an elastic
fit is thus obtained between the parts. The tubular carrier e is guided in its
movements by means of a guide bar d' or guide studs might be employed in lieu
thereof projecting from the inner tube d of the wick case at its lower end and
bearing against the edges of the tubular carrier e bordering the vertical slot or
opening e
In order to detachably connect the lower end of the winder rack with the lower
end of the tubular carrier e of the wick raiser and to automatically centralise the
same with relation thereto a cone f³ is fixed upon the lower end of the rack and
at the lower end of the tubular carrier e a circular aperture e is provided which
receives the cone ƒ³ so that upon the rack being wound downwards until the
cone ³ engages the aperture ³ of the tubular carrier the parts will be truly
centralised.
In order to fix the cone f³ of the rack f with the lower end of the tubular
carrier e the cone f³ has formed thereon studs or projections f* and in connection
therewith is employed an apertured washer or nut g which is adapted to take a
bearing upon the lower end of the tubular carrier e and is slotted or notched at g¹
to correspond with the studs or projections f* of the cone f³ as shown more
particularly at Figures 8 to 11 so that in one position it will pass over such studs,
and when turned by means of its projections 92 will lock the cone f³ with the
tubular wick carrier e as represented more particularly at Figures 1, 3, and 5.
In the example given at Figures 12ª the apertured washer or nut g is rendered
inseparable from the tubular carrier e so as to prevent the same becoming mislaid
or lost.
For this purpose the apertured washer or nut g is held in position upon the end
of the tubular wick carrier e by means of a ring et connected with the tubular
carrier e by straps es which at the same time in conjunction with the projections g²
upon the washer or nut g form stops to arrest the rotary movement of the washer
in either of its extreme positions.
By this constructions of parts it is possible by simply turning the washer or nut g
to remove the tubular carrier e from the inner tube d of the burner thus taking
away bodily the claws or wick raiser e¹ and leaving the wick case perfectly open
and free for the insertion of the wick at the lowest end thereof as represented more
particularly at Figure 12 after which the tubular wick carrier e may be placed in
position so that its claws el engage the wick at a suitable distance from the top edge
thereof and again fixed with the rack f as represented more particularly at Figure 1,
when the burner is ready for use.
By this arrangement of parts it is possible to almost instantaneously insert a wick
and that without the necessity for skilled knowledge as the wick tube is free from
any impediment in the shape of claws added to which the wick raiser e in practice
raises the wick with greater truth than heretofore by reason of the tubular carrier e
being continuously guided and steadied in its movements by the guide bar d'.
Referring to Figures 13. to 17 which more particularly represents the second part
of the invention, a represents the container or reservoir and b represents the
burner.

page_text: Hydro-carbon burners are commonly connected with their reservoirs or containers a
by means of a simple form of clamping device or joint consisting of two inclined
projections a' on the collar of the container which are embraced by corresponding
clips upon the body of the burner so that upon placing the burner in position.
and turning it a given distance it will by reason of the inclines a¹ be connected more
or less tightly with the neck or collar of the container a.
This is a ready means of connecting a burner with its container but it possesses.
the disadvantage that if the connection is not carefully made, the burner b' is liable
from vibration or other causes to turn back and become disconnected from the
container a the inclines a' of the clamping device or joint facilitating this action.
and serious accidents have resulted from this cause.
Now according to the second part of the present invention it is proposed by a
very simple and inexpensive device to render such an accident impossible.
For this purpose the burner b--which carries the clips 6' is provided with a locking
device which consists of a plate spring curved to the circular shape of the burner
and provided with a returned end 63 adapted to engage the broad end a² of one of
the inclines a' on the collar or ring of the container a whilst the opposite end of
this spring is fixed to the burner at b. The spring has formed therein and
the ring of the burner has correspondingly formed therein a curved slot through
both of which is passed a stud 6 at its upper end formed with a head and at its
lower end flanged so as to render it inseparable from the ring and thus by moving
this stud 66 by its head 6 in one direction or the other the returned end of the
spring will be either raised out of or lowered into engagement with the broad end
of the incline a².
By means of this device which is both simple and inexpensive the burner may be
securely locked against accidental separation from the container.
It will be understood that this part of the invention is equally applicable to other
classes of burners than that herein shown and described and such as flat wick
burners.
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 :-
1. In an Argand hydro-carbon burner the combination of a wick case the outer
tube of which is formed in one piece and a removeable carrier tube and claws.
substantially as herein shown and described and for the purpose stated.
2. In an Argand hydro-carbon burner a removeable carrier tube and claws.
substantially as herein shown and described and for the purpose stated.
3. In an Argand hydro-carbon burner the combination of a removeable carrier
tube for the claws formed with an open ended slot or split, a guide bar or studs or
the like upon the inner tube of the wick case adapted to be embraced by the edges.
of the carrier tube bordering the slot and means for detachably connecting the rack
rod of the winder with the lower end of the carrier tube substantially as herein
shown and described and for the purpose stated.
4. In an Argand hydro-carbon burner the combination of a removeable carrier
tube and claws an apertured ring at the lower end of the carrier tube, a cone upon
the lower end of the rack rod and means for detachably connecting the cone with the
ring substantially as herein shown and described and for the purpose stated.
5. In an Argand hydro-carbon burner the combination of a removeable carrier
tube and claws an apertured ring at the lower end of the carrier tube, a cone upon
the lower end of the rack rod, an apertured washer or nut adapted to take a
bearing upon the ring of the carrier tube studs or projections upon the cone and
corresponding notches in the washer or nut substantially as herein shown and
described and for the purpose stated.
6. In a hydro-carbon lamp in which the container is provided with inclines and
the burner with clips adapted to engage the inclines or vice versa in order to unite
these parts the combination therewith of a locking device consisting of a spring.
