We, DONALD BARNS MORISON of South Crescent, Hartlepool in the County of
Durham, Engineer, and GEORGE JESSE PURSER of Trafalgar Works, Palmer Street
Birmingham in the County of Warwick Manufacturer, do hereby declare the nature
of this invention to be as follows:-
-
This invention relates to means for the raising and lowering of the wick or wicks of
lamps, and consists of an improved apparatus, whereby the said wick or wicks, is or
are raised and lowered, and which said apparatus is actuated preferably from, at or
near the bottom of the oil reservoir, by means of an axial rod (disposed vertically)
connected with the wick adjusters.
We will describe our invention in connection with a suspended lamp, with a circular
wick, and an internal air tube.
At or near the middle of the burner body, or down the axis of the air shaft of the
burner body, an axial rod is disposed, which is wormed at or near its upper end, and
with the wormed end gearing with three or other number of radially disposed winder
wheels, supported and working in bearings or brackets suitably arranged within the
central air shaft.
The screwed ended rod, may be limited in its rising and falling motion by stops.
The lower terminal end of the central rod or axis aforesaid, is provided with a head,
by means of which, the said axial rod is rotated, while the teeth of the winder wheels,
pass through gaps or openings in the sides of the air tube, so as to penetrate or get to
the wick or wicks, which is or are disposed around the external surface of the central
air tube in the usual manner.
Thus in the aforesaid example the winding mechanism, and the axial rod of the
wick adjuster, are disposed within the central air shaft.
The rotation of the axis, to the right or left, by the head protruding through the
bottom of the oil reservoir, causes the winder wheels with which it is in gear, to raise
or lower the wick.
The axial rod aforesaid, may have a rising and falling motion, or it may be
stationary, with the teeth of the winder wheel slightly skewed, after the manner of a
tangent wheel.

page_text: Instead of disposing the winder wheels within the air shaft, they may be suitably
arranged around the circumference of the outer tube, and with their teeth protruding
inwardly through gaps, in the sides of the said tube, in order to get to the wick.
An internally screwed annulas or ring surrounds and gears with the teeth of the
sud wheels, which on being rotated to the right or left turns the winder wheels, and
raises or lowers the wick. This screwed annulas, may either have a rising and falling
motion within guides, or it may be made stationary.
If a worm he formed on the end of the axial rod, and geared with a rack (with
inclined teeth) on the outer surface of the annulas or ring, the axial rod may be
horizontal, and above the oil reservoir.
The ring or collar may either be worked by hand, or it may be operated by a
pinion on the end of a rod or winder axis, engaging with rack teeth on its upper or
lower sides.

COMPLETE SPECIFICATION.
Improvements in Hydro Carbon and other Oil Lamps.
We, DONALD BARNS MORISON of South Crescent, Hartlepool in the County of
Durham, Engineer, and GEORGE JESSE PURSER of Trafalgar Works, Palmer Street
Birmingham in the County of Warwick, 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 :-
This invention relates to means, for the raising and lowering of the wick, or wicks
of lamps and consists, of an improved apparatus, whereby the said wick or wicks, is
or are raised, and lowered, and which said apparatus, is actuated preferably from, at,
or near the bottom of the oil reservoir, by means of an axial rod, (disposed vertically)
connected with the wick adjusters or winders.
We will describe our invention, in connection with a suspended lamp, with a circular
wick, and an internal air tube.
At or near the middle of the burner body, or down the axis of the air shaft, of the
Burner body, an axial rod is disposed, which is wormed at or near its upper end, and
with the said wormod end, gearing with three or other number of radially disposed

page_text: winder wheels, supported and working in bearings, or brackets, suitably arranged,
within the central air shaft.
The axial rod, with worm at its upper end, is supported, and confined, by suitable
bracket bearings.
The lower terminal end of the central rod or axis aforesaid, is provided with a turn,
by means of which, the said axial winder rod, is rotated, while the teeth of the winder
wheels, pass through gaps or openings in the sides of the air shaft, in order to get to
the wick or wicks, which is, or are disposed around the external surface of the central
air tube, and between a secondary outer tube, in the usual manner,
Thus, in the aforesaid example, the winding mechanism, and the axial rod of the
wick adjuster, are disposed within the central air shaft.
The rotation of the axis, to the right, or to the left, by the turn or head as aforesaid,
which protrudes through the bottom of the oil reservoir, causes the winder wheels,
with which it is in gear, to raise or lower the wick or wicks, according whether one
or more wicks are used.
Instead of disposing the winder wheels within the air shaft, they may be suitably
arranged around the circumference of the outer tube, and with their teeth protruding
inwardly, through gaps, in the sides of the said tube, in order to get to the wick.
An internally screwed annulas or ring, surrounds and gears with the teeth of the
said wheels, which on being rotated to the right or left, turns the winder wheels,
and raises or lowers the wick. This internally screwed annulus or collar, is rotated,
between fixed guides, either by hand, or by gear.
We will now proceed to describe with reference to the accompanying drawings,
the manner in which the same is to be performed.
Figure represents in elevation, a suspended lamp, with circular wick, provided
with winder means, constructed according to our invention. Figure 2 is a vertical
section of the same, exhibiting the winder, consisting of a worm carried by an axis,
and gearing with star like winder wheels, arranged and supported at equi-distani
points, within the air shaft. Figure 3 is a plan of the underside of figure 1, and
figure 4 is a section upon the dotted lines A B figure 2.
The same letters of reference indicate corresponding parts in figures 1, 2, 3 and 4
of the drawing.
a is the burner body, 6 is the oil container of the lamp, c is an air shaft up its
middle, through which air for supplying combustion to the burner, is conducted.
d is a winder axis, supported within the middle of the said air shaft, by a collar and
brackets d, e, e²; and which said axis d, carries at its upper end, a worm or screw d³,
which gear with, three or other number of radially disposed winder wheels, sup
ported and working within bracket bearings g, arranged and supported within the
central air shaft.
The winder wheels, pass outwardly through piercings e², made in the sides of the
air shaft, and take into the wick or wicks h, disposed between the outside of the tube,
constituting the air shaft, and the inside of a secondary fixed tube i.
The winder axis d, which as aforesaid, is supported and carried by bracket bearings,
has at its lower end, a turn d', by means of which, the winder axis is rotated, and
motion given to the winder wheels, which raise and lower the wick, or wicks, as
may be desired.
Thus, to raise the wicks, turn the winder axis from left to right, when the worm or
screw d³, carried by it, gears with, and rotates simultaneously, the winder wheels f
thereby raising the wick or wicks.
To lower the wick or wicks, rotate the winder axis in the reverse direction, when
the star wheels, which are in gear with its wormed end, are reversed.
In figure 5, the winder axis is supported at top, as well as bottom, while the
winder wheel axes or spindles, are supported and work within sloeves, secured within
the tube of the central air shaft.
c is the air shaft, d is the winder axis, d³ is the worm, are the winder wheels,
and are their axes, supporied and working within sleeve bearings 7³, secured within
the central air tube c.

page_text: Figure 6 is a plan of figure 5.
Figure 7 is a modified form of my invention, in which an internally wormed
annulus, or collar, is made to gear with the teeth, and work a number of winder
wheels, supported in suitable bearings, arranged around the outer wick tube.
c is a central air shaft, and i is an outer tubing, with limiting flanges, between
which, an internally wormed annulus or collar, rotates. The threads of the wormed
internal part as aforesaid, gear with the teeth of three, or more winder wheels, whose
axes work within the bearings, of side brackets, carried by the outer tube i, and
enclosed by the annulus k.
The inside presented edges of the wheels, pass through gaps or openings, in the
outer tube i, by means of which, the wick is raised or lowered.
To raise the wick, rotate the annulus or collar k, from left to right, when the
wormed inside part, simultaneously rotates, and turns the wheels downwards,
whereby the wick is raised.
To lower the wick, the reverse action takes place.
Figure 8 represents a transverse section of figure 7, showing the positions of the
winder wheels, with respect to the wick, and internally wormed annulus.
The winder wheels inwardly pass to the wicks, through the inside walls of the wick
cases.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is-
First. Winding the wicks of lamps, by making the winder wheels, pass inwardly
to the wicks, through slits or gaps, made in the sides or walls of the tube, forming the
air shaft, of a burner or lamp, substantially as described and set forth.
Secondly Raising and lowering the wicks of circular burners, by ordinary winder
wheels, arranged and mounted within the air shaft, and worked in unison, and simul-
taneously, by a worm or screw, carried by a centrally disposed winder rod, worked
from below, and passing up the middle of the air shaft, substantially as described and
set forth in figures 1, 2, 3, 4 and 5.
Thirdly. Working externally arranged, and mounted wick winders, or winder
wheels, in connection with circular wicks, by means of an internally wormed collar or
annulus, substantially as described and set forth in figures 7 and S.
Lastly. The combination with a circular wick burner, of winder wheels, and an
internally screwed collar k, as set forth in figures 7 and 8.
Dated this Third day of December 1887.
