The said sleeve is operated by a lever arranged at the side of the wick-tube or
tubes and projecting through the side of the burner, the said lever carrying on its
inner end two or more prongs which act. upon the said sleeve. The said lever is
so arranged as to admit of its vertical or horizontal movement. The before-
mentioned dogs are held out of contact with the wick by means of wedges or cams
on a second lever. The second lever also carries a cam which acts upon the first
lever in such a manner that by the depression of the two lovers, the dogs seize the
wick, the sleeve is acted upon by one or more of the prongs on the first-mentioned
lever and the wick can be raised or lowered as desired. By means of the first-
mentioned lever the sleeve can be, moved downward and a renewed grip of the
wick taken at a lower point than before. A spring catch is provided to retain
the wick in its position when released from the dog or dogs. A slotted bar and
set-screw are provided on the outside of the burner by means of which the said
lever can be securely retained in any desired position. Or may employ two
levers pivotted to each other and to the burner and extending inward to the front
and back of the wick-tube. The inner ends of one or both of the said levers are
formed or fitted with prongs or teeth for seizing the wick through a slot or slots.

'I WILLIAM SANDBROOK of Ebbw Vale in the County of Monmouth, Ironmonger
do hereby declare the nature of the said invention for "IMPROVEMENTS IN LAMP
BURNERS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawing forming a part of this specification:-
My invention relates to burners of oil lamps, of all descriptions, and the object
of my invention is to provide improved means whereby the wick or wicks of the
said lamps can be readily raised or lowered and their height regulated as may be
desired.
My invention consists in regulating the height of the wick or wicks by means
of one or more levers carrying, or acting in conjunction with suitable devices
whereby the wick or wicks can be seized or released and raised or lowered as
desired.

page_text: Figure 5 is an elevation, partly in section of a lamp burner showing a modifica-
tion of my invention applied to a single-wick burner.
Figure 6 is a plan of the same.
Figure 7 is a sectional elevation showing a further modification of my invention.
Like letters indicate like parts in all the figures.
Figures 1 and 2 illustrate one method of carrying out my improvements, as
applied to a lamp with a duplex burnor, but this method is equally applicable to
single wick burners. a is a sleeve sliding freely upon the wick tube b. The said
sleeve is provided with a spring dog c for each wick tube and the upper end of
the said dog is provided with teeth o¹ which enter the wick through slots d in the
wick tube b. A lever e is pivotted in the side of the burner at f through a slot e¹
in the said lever so that it is capable of a vertical and longitudinal movement
and the said lever projects from the burner so as to be readily operated from the
outside of the said burner. The inner end of the said lever carries two prongs c³ ³
for each wick. The upper prong e passes between the dog c and the sleeve a;
the lower prong e³ passes through a suitable eye or guide a¹ on the said sleeve.
The end of the upper prong e carries a wedge or cam e*. When the parts are in
the positions shown in Figures 1 and 2 the wick can be raised by simply depressing
the lever e. By giving the lever e a longitudinal movement outward so as to
.bring the came on the prongs e² between the dogs c and the sleeve a the teeth c¹
of the said dogs are withdrawn from the wicks. Then by raising the lever e the
sleeve a is caused to slide down the wick tube b a longitudinal inward movement
of the said lever releases the dogs c from the cams e* and a renewed grip of the
wick is taken at a lower point than before.
Figures 3 and 4 illustrate a simple method of applying my improvements to
a common single-wick burner. The lever e is pivotted at f to the side of the
burner, the said lever being contained within a sleeve g also pivotted at f. The
said lever carries on its inner end two arms or prongs hi and its outer end is
provided with a stud j projecting through the sleeve g. The end of the prong h
is turned at right angles as shown at h¹ and enters the wick tube b through a slot
in the side of the said tube, the said portion h¹ being provided with a sharp edge
or with teeth for seizing the wick. On the other side of the wick tube is a
spring k having at its upper end a prong k¹ which enters the wick through a hole
in the wick tube b (as shown in figure 3) and prevents the wick from falling
down the tube. Both the lever e and sleeve g have a vertical movement and the
levere has a lateral movement within the said sleeve. When the stud j is.pressed
inward, the portion of the arm or prong h seizes the wick and at the same time
the arm or prong i forces back the spring k and its prong k' releasing the wick
therefrom so that by a downward movement of the outer end of the lever e and
sleeve g the wick can be raised. On the stud j being relieved from pressure the
spring causes the lever e and its arms h and i to return to their original position
and the prong k¹ on the spring / re-enters the wick and retains it in position.
This form of my invention may also be modified and adapted to suit duplex
burners.
'
In the above described methods of carrying out my improvements the lever is
pivotted in the burner at the end of or in line with the wick tube. In figures 5
and 6 is shown a modification of my improvements wherein the levers are pivotted
in front of or at right angles to the wick tube b. The levere is pivotted at f to
the side of the burner through a slot e¹ in the said lever so as to admit of its
longitudinal as well as vertical movement. The said lever carries on its inner end
one or more toothed prongs or arms e³. The cam lever is also pivotted at f so as
to have a vertical movement only, and by depressing this lever its inner end l
forces the toothed prongs or arms e³ into the wick through slots or apertures in the
wick tube b the said prongs or arms being forced out of contact with the wick
when the levers are released by the action of a spring m secured to the wick tube
between the said tube and the arms or prongs e³ of the lever e. The upper end

page_text: of the said spring carries a wire n bent around the wick-tube b.the said wire being
provided with a point or prong n' which enters the other side of the wick tube b
through a suitable hole or aperture and holds the wick from slipping downward when
the prongs are out of contact with the said wick. The action of this arrangement
is as follows: The lever being depressed the prongs or arms are forced into the
wick and at the same time the spring m is prossed towards the wick tube b and the
wick released from the prong n¹. The wick can thon be raised by depressing the
lever e. By releasing both levers the prong n¹ enters and sustains the wick and
then by elevating levere and depressing lever la renewed grip of the wick can be
obtained at a lower point or by depressing first the lever e and then the lever
the wick can be seized towards the top of the tube and the wick lowered in the
said tube. The lever Z may be arranged by the side of the lever c or work within
a longitudinal slot in the said lever e (as shown in Figure 7). Or the lever 7 may
be dispensed with and the necessary longitudinal movement of the lever e be
imparted by hand. Also instead of the spring m being arranged, as shown in
figures 5 and 6 a spring and prong may be arranged on the other side of the
.wick tube as shown in figure 7, the said spring boing forced away from the wick
tube and the wick released from the prong by a wire o or other suitable device
fixed to the inner end of the lever c.
In order to lock the lever or levers and prevent their being tampered with
after the wick is adjusted to the desired height I provide on the under side of
the burner a screw p, which can be screwed under the said levers so as to sustain
them against the underside of the flange of the burner and prevent their being
depressed.
I have herein described and shown various methods of applying my improve-
ments but I do not limit myself to the details herein set forth as the same may
be varied in many ways without departing from my invention. Thus two. levers
may be employed pivotted to each other and to the burner and extending. inward
to the front and back of the wick tube. The inner ends of one or both of said
levers may be formed or fitted with prongs or teeth for seizing the wick through
a slot or slots in the wick tube, the wick being raised or lowered by operating the
levers upon their pivots in the side of the burner. Any other suitable devices for
-seizing or grasping the wick or wicks and for sustaining the same in the wick tube
or tubes may also be employed.
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

page_text: I, WILLIAM SANDBROOK, of Ebbw Vale in the, County of Monmouth, Ironmonger,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN LAMP
BURNERS," to be as follows:-
The object of my invention is to provide improved means for raising or lowering
the wick and regulating the same as desired.
My invention consists in regulating the height of the wick by means of one or
more levers. I provide the wick-tube or tubes with a sleeve adapted to slide upon
the said tube or tubes, the said sleeve having one or more spring dogs which seize
the wick through a slot or slots in the wick-tubes.
The said sleeve is operated by a. lever arranged at the side of the wick-tube or
tubes and projecting through the side of the burner, the said lever carrying on its
inner end two or more prongs which act upon the said sleeve. The said lever is
so arranged as to admit of its vertical or horizontal movement. The before-
mentioned dogs are held out of contact with the wick by means, of wedges or cams
on a second lever. The second lever also carries a cam. which acts upon the first
lever in such a manner that, by the depression of the two levers, the dogs seize the
wick, the sleeve is acted upon by one or more of the prongs on the first-mentioned
lever and the wick can be raised or lowered as desired: By means of the first-
mentioned lover the sleeve can be moved downward and a renewed grip of the
wick taken at a lower point than before. A spring catch is provided to retain
the wick in its position when released from the dog or doga. A slotted bar and
set-screw are provided on the outside of the burner by means of which the said
lever can be securely retained in any desired position. Or I may employ two
levers, pivotted to each other and to the burner and extending inward to the front
and back of the wick-tube. The inner ends of one or both of the said levers are
formed or fitted with prongs or teeth for seizing the wick through a slot or slots
in the wick-tube the wick being raised or lowered by operating the levers upon
their pivots in the side of the burner. By pressing the outer end of one or both
the said levers the wick can be released and a renewed grip of the same taken at
any desired point. Or the wick may be raised or lowered by means of a lever

Like letters indicate like parts in all the figures.
Figures 1 and 2 illustrate one method of carrying out my improvements, as
applied to a lamp with a duplex burner, but this method is equally applicable to
single wick burners, a is a sleeve sliding freely upon the wick tube b. The said
sleeve is provided with a spring dog c for each wick tube and the upper end of
the said dog is provided with teeth c which enter the wick through slots d in the
wick tube b. A lever c is pivotted in the side of the burner at f through a slot e¹
in the said lever so that it is capable of a vertical and longitudinal movement
and the said lever projects from the burner so as to be readily operated from the
outside of the said burner. The inner end of the said lever carries two prongs e²es
for each wick. The upper prong e² passes between the dog c and the sleeve a;
the lower prong es passes through a suitable eye or guide a¹ on the said sleeve.
The end of the upper prong e¹ carries a wedge or cam e. When the parts are in
the positions shown in Figures 1 and 2 the wick can be raised by simply depressing
the lever e. By giving the lever e a longitudinal movement outward so as to
bring the came on the prongs e¹ between the dogs c and the sleeve a the teeth c¹
of the said dogs are withdrawn from the wicks. Then by raising the lever e the
sleeve a is caused to slide down the wick tube b a longitudinal inward movement
of the said lever releases the dogs e from the cams e* and a renewed grip of the
wick is taken at a lower point than before.
Figures 3 and 4 illustrate a simple method of applying my improvements to
a common single-wick burner. The lever e is pivotted at f to the side of the
burner, the said lever being contained within a sleeve g also pivotted at f. The
said lever carries on its inner end two arms or prongs hi and its outer end is
provided with a studj projecting through the sleeve g. The end of the prong h
is turned at right angles as shown at h¹ and enters the wick tube b through a slot
in the side of the said tube, the said portion h¹ being provided with a sharp edge
or with teeth for seizing the wick. On the other side of the wick tube is a
spring k having at its upper end a prong which enters the wick through a hole
in the wick tube b (as shown in figure 3) and prevents the wick from falling
down the tube. Both the lever e and sleeve have a vertical movement and the
levere has a lateral movement within the said sleeve. When the stud j is pressed
inward, the portion of the arm or prong h seizes the wick and at the same time
the arm or prong i forces back the spring and its prong releasing the wick
therefrom so that by a downward movement of the outer end of the lever e and
sleeve g the wick can be raised. On the stud; being relieved from pressure the
spring k causes the lever e and its arms h and i to return to their original position
and the prong k¹ on the spring re-enters the wick and retains it in position.
This form of my invention may also be modified and adapted to suit duplex
burners.
In the above described methods of carrying out my improvements the lever is
pivotted in the burner at the end of or in line with the wick tube. In figures 5
and 6 is shown a modification of my improvements wherein the levers are pivotted
in front of or at right angles to the wick tube b. The lever e is pivotted at f to
the side of the burner through a slot e' in the said lever so as to admit of its
longitudinal as well as vertical movement. The said lever carries on its inner end
one or more toothed prongs or arms e³. The cam lever is also pivotted at ƒ so as
to have a vertical movement only, and by depressing this lever its inner end l
forces the toothed prongs or arms e into the wick through slots or apertures in the
wick tube b the said prongs or arms being forced out of contact with the wick
when the levers are released by the action of a spring m. secured to the wick tube
between the said tube and the arms or prongs of the lever e. The upper end

page_text: of the said spring carries a wire n bent around the wick-tube b the said wire being
provided with a point or prong n' which enters the otlier side of the wick tube b
through a suitable hole or aperture and holds the wick from slipping downward when
the prongs e are out of contact with the said wick. The action of this arrangement
is as follows: The lever being depressed the prongs or arms e³ are forced into the
wick and at the same time the spring m is pressed towards the wick tube b and the
wick released from the prong n¹. The wick can then be raised by depressing the
lever e.
By releasing both levers the prong n¹ enters and sustains the wick and
then by elevating lever e and depressing lever la renewed grip of the wick can be
obtained at a lower point or by depressing first the levere and then the lever
the wick can be seized towards the top of the tube and the wick lowered in the
said tube. The lever 7 may be arranged by the side of the lever c or work within
a longitudinal slot in the said lever e (as shown in Figure 7). Or the lever / may
be dispensed with and the necessary longitudinal movement of the lever e be
imparted by hand. Also instead of the spring m being arranged, as shown in
figures 5 and 6 a spring and prong may be arranged on the other side of the
wick tube as shown in figure 7, the said spring being forced away from the wick
tube and the wick released from the prong by a wire o or other suitable device
fixed to the inner end of the lever e.
In order to lock the lever or levers and prevent their being tampered with
after the wick is adjusted to the desired height I provide on the under side of
the burner a screw p, which can be screwed under the said levers so as to sustain
them against the underside of the flange of the burner and prevent their being
