PROVISIONAL SPECIFICATION.
Improvements connected with Lamp Burners.
I, HENRY SALSBURY, of 125 and 126 Long Acre, London, Lamp Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention has for object, the raising and lowering of lamp wicks by a
rotating shell on the exterior, or as part of the burner base, the shell being screw
threaded on the interior to engage in the teeth of the star, or lifter wheel or
wheels, either directly, or through the intermediation of other wheels, one, or some
of which may be worms or bevel, according to the construction of the burner or of
the number of wicks employed in one.
For what are known as spirit lamps, the wick can be raised and lowered by the
dome or head which fits on the base, in which case the dome or head would have
the star wheel or wheels fitted on the wick tube.

COMPLETE SPECIFICATION.
Improvements connected with Lamp Burners.
I HENRY SALSBURY of 125 and 126 Long Acre, London, Lamp 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 has for object the raising and lowering of lamp wicks by a
rotating shell on the exterior or as part of the burner base, the shell being screw
threaded on the interior to engage in the teeth of the star or lifter wheel or
wheels.
The invention is chiefly intended for use with oil reservoirs of a long cylindrical
form for being dropped into the candle sockets of carriage and like lamps in
substitution for ordinary candles.
The annexed drawings Figures I II and III show my invention as applied to
the burner portion of single round wick lamps such as are used in substitution for
candles in carriage lamps.
According to the sectional elevation Figure 1 the base A. of the burner is
provided on its interior portion with a screw thread B into which gears a star or
lift wheel C attached to the wick tube D for raising or lowering the wick E when
the rim F is turned.
The wick tube fits loosely in the base A and has its end burred over at a to
prevent its withdrawal.
G is an extension of the base A and provided with a screw thread for connection
to the lamp reservoir H.
I is a cap which acts as a distancing piece between the rim F and base A.
According to the modification shown at Figure 3 the screw thread B into which
gears the star or lift wheel C is on a dome or head J, this being kept in position by
a rim or lips K of the base A. The rim F in this case is part of the dome J the
rim being turned to move the star wheel for raising or lowering the wick. The
tube D is a fixture to the base A.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of lamp burner substantially as represented by Figure 1 of
the annexed drawings, and in which by the turning of the wick tube a star wheel
is moved for raising or lowering the wick as described.
2. The construction of lamp burner as represented by Figure 3 of the annexed
drawings and in which on the turning of a dome or head having a screw thread on
its interior surface a star wheel is moved for raising or lowering the wick as
described.
