Improvements in Wick Regulating Devices for Lamps.
I, EUSEBIO FRANCISCO CABEZOLA of 489 Chestnut Avenue, Trenton, New Jersey,
United States of America, Elecrician, 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 is a device for raising and lowering lamp wicks, and is especially
adapted to tubular wicks.
In the drawings Fig. 1 is a vertical section on the line 1, 1 of Fig. 2 of the bowl of
a lamp provided with my device. Fig. 2 is a horizontal section on the line 2, 2 of
Fig. 1. Fig. 3 is a vertical section on line 3, 3 of Fig. 2.
Similar letters of reference indicate like parts.
A is the lamp reservoir. B the inner tube, C the wick, D the outer tube and E the
chimney supporting cap; said parts being of any approved form of Argand or central
draft burner.
The wick raising device is secured on the under side of the top F of the reservoir.
G G are spindles supported at their inner ends in brackets H, and at their outer ends
in arms I of bracket J. On spindles G are toothed wheels K K and L L which engage
wick C. Between said spindles is a vertical worm gear, the spindle M of which is
stepped in projection N on bracket J, passes through a tube O in the top of the
reservoir, and is provided with a head P. The spiral Q of the worm engages with
gear wheels R on the spindles G, the said wheels having broad teeth which substantially
fill the space on spindle M between the turns of spiral Q, so that lost motion or
slipping is thus avoided.
By rotating the head P the spindles G are simultaneously revolved, and the toothed
wheels K K, L L then engage with the wick and raise or lower it.
The worm gear dispenses with the rod generally used to raise the wick in this class
of lamps and the gear wheels are so secured in operative relation to the worm gear that
they cannot be displaced or disengaged by any jar to which the lamp may be subjected.
The toothed wheels K K engage the wick on both sides and feed it evenly. The
spiral Q may be formed separately of wire and secured to the spindle M.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, I declare that I
claim is
1. A device for raising or lowering a lamp wick, comprising two spindles having
toothed wheels respectively disposed on each side of the wick, and engaging therewith
and a worm gear for rotating said wheels simultaneously, substantially as described.
2. A device for raising and lowering a lamp wick comprising two spindles having
toothed wheels respectively disposed on each side ofthe wick, and engaging therewith,
a worm vertically disposed between said spindles and engaging with gears thereon, the

page_text: said worm and gears being constructed substantially as set forth, and means for
operating the worm from the exterior of the lamp reservoir, substantially as described.
Dated this 12th day of May 1897.
