PROVISIONAL SPECIFICATION.
A "Spiral Regulator" for Regulating the Flame of Benzoline and
other Lamps.
I, JOHN HALL, 6 Houghton Road, Tottenham, in the County of Middlesex,
Journalist, do hereby declare the nature of this invention to be as follows:-
=
The object is to regulate the flame of lamps burning benzoline, petroleum or other
oils without the use of the usual rack and pinion which raises or lowers the wick, but
soon gets out of order.
Upon the usual tube or tubes carrying the cotton wick I place on the outside an
additional tube fitting closely to the said tube.
In this outer tube is cut a spiral slot which works upon a pin or spiral groove, and
when a twisting motion is given to it, gives a rising or falling motion to the
regulating tube. Instead of the wick being raised or lowered the upper edge of
the tube impinges upon the lower part of the flame and regulates its height. Upon
the regulating tube is a bead of wood, cork, ivory, bone, vulcanite, asbestos or other
nonconducting medium, to facilitate the moving of the tube.

A "Spiral Regulator" for Regulating the Flame of Benzoline and
other Lamps.
I, JOHN HALL of 6 Houghton Road Tottenham in the County of Middlesex,
Journalist, 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 nature of my invention is to provide a better means of regulating the flame of
benzoline lamps and of circular or argand paraffin or other oil lamps.
In the accompanying drawings in the figures of which like parts are indicated by
the same letter, I illustrate the manner in which the regulator is constructed.
Figure 1, is an elevation of a benzoline lamp with the regulator attached.
Figure 2, shows the lamp iube with the regulator removed; and
Figure 3, is the regulator.
The design or shape of the body of the lamp is immaterial, as the invention relates
only to the portion carrying the wick.
I place outside the usual tube A, carrying the cotton wick an additional tube B,
fitting closely to the tube A. In this outer tube is cut a spiral slot, C, which works
upon a pin D, fixed to the wick tube and which when the outer or regulating tube B
is moved gives a spiral or rising and falling motion to the said regulating tube. Or
the said motion may be produced by a raised spiral thread or worm, moulded in the
outer tube working upon a similar thread moulded upon the inner tube.
The action of the regulator upon the flame is as follows. In lieu of the wick being
raised or lowered as by the ordinary rack and pinion, the outer regulating tube, by a
slight twist, rises and impinges upon the lower edge of the flame, thereby regulating
it to the degree required. For the purpose of better working the regulator in the
case of the benzoline lamps, I fix upon the spiral regulator a bead of wood, cork,
ivory, bone, vulcanite or other non-conducting medium.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The provision of a tube outside the ordinary wick tubos of oil and benzoline lamps
which being raised or lowered regulates the flame without moving the wick.
Dated this 18th day of October 1890.
