IMPROVEMENTS IN LAMPS FOR BURNING HYDRO-CARBON OILS
Year: 1884

page_text: PROVISIONAL. SPECIFICATION.
I, ALBERT CHARLES JONES, of Broad Street, Birmingham, in the County of
Warwick, Manufacturer, do hereby declare the nature of my invention for
IMPROVEMENTS IN LAMPS FOR BURNING HYDRO-CARBON OILS to be as follows:―
This Invention relates to the means of raising and lowering the wicks of lamps
of those types in which are two wicks, either parallel to each other, or forming
halves of a circular arrangement of wicks.
The object of the invention is to effect the raising and lowering of each wick in
turn by means of a single spindle placed between the two wicks.
This spindle is carried at one end by a rocking bearing, and its other end passes
through a horizontal slot in the side of the burner, and is extended outwards to
carry the button for manipulating the said spindle.
In its normal position the spindle passes between the two wicks at an equal
distance from each.
On the part of the spindle between the wicks are toothed discs for raising and
lowering the wicks by the rotation of the spindle.
These toothed discs are of such a diameter that their teeth just clear both wicks
when the spindle is in its normal central position.
To wind either wick up or down, the spindle is pushed sideways so as to bring
the toothed discs to bear against that wick which is to be operated upon, and the
spindle is rotated in the required direction.

page_text: I, ALBERT CHARLES JONES, of Broad Street, Birmingham in the County of
Warwick, Manufacturer, do hereby declare the nature of my invention for
IMPROVEMENTS IN LAMPS FOR BURNING HYDRO-CARBON OILS 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 the means of raising and lowering the wicks of lamps
of those types in which are two wicks, either parallel to each other, or forming
halves of a circular arrangement of wicks.
The object of the invention is to effect the raising and lowering of each wick in
turn by means of a single spindle placed between the two wicks.
This spindle is carried at one end by a rocking bearing, and its other end passes
through a horizontal slot in the side of the burner, and is extended outwards to
carry the button for manipulating the said spindle.
In its normal position the spindle passes between the two wicks at an equal
distance from each.
On the part of the spindle between the wicks are toothed discs for raising and
lowering the wicks by the rotation of the spindle.
These toothed discs are of such a diameter that their teeth just clear both wicks
when the spindle is in its normal central position.
To wind either wick up or down, the spindle is pushed side ways so as to bring
the toothed discs to bear against that wick which is to be operated upon, and the
spindle is rotated in the required direction.
In the accompanying drawings the improved winder is shewn in plan. In
Fig. I the winder is shewn as pushed over to act on the left hand wick;
and its position when required to act on the right hand wick is shewn in dotted
lines. In Fig. II the winder is shewn in its normal position, acting upon neither
wick.
a is the spindle, carried at one end in the rocking bearing b, and passing at c
through a horizontal slot in the side of the burner. d d' are the toothed discs
which act on the wicks in the wick tubes e e. f is the button for manipulating the
spindle a. .'
When the winder acts upon the left hand wick a right hand turn of the button
raises the wick, while a left hand turn lowers it: and when the winder acts upon
the right hand wick these conditions are reversed.
The coiled spring g steadies the spindle, and holds the loose piece ħ against the
body of the burner.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what mannor the same is to be performed, I declare that what
I claim is
. The single winder spindle between the two wicks, carried by a rocking bearing
at one end and passing through a horizontal slot in the body of the burner at the
other end, and acting by the toothed discs upon either wick in turn to raise or
lower the same, as described and illustrated,
