PROVISIONAL SPECIFICATION.
Improvements in Lamps and Lamp Wicks.
BURTON RICHARD PHILLIPSON of 10 Lower Baggot Street Dublin Engineer
do hereby declare the nature of this invention to be as follows:-
I use upon lamps having circular wicks, a wick with a metal ring or collar
secured to it, which ring or collar is provided with a bayonet joint, spring, or other
means of attachment to the lamp. The metal collar is so arranged that it can be
taken on or off the portion of lamp which receives it, at will.
I make centre draught lamps in which the wicks are raised by the turning of a
screw, upon the head of the said screw I use a cogged wheel which is driven
by a second cogged wheel working upon it.
Dated this Twenty-sixth day of February 1892.

COMPLETE SPECIFICATION.
Improvements in Lamps and Lamp Wicks.
BURTON RICHARD PHILLIPSON of Lower Baggot Street Dublin Ironmonger
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 :-
According to my present invention which applies to what is known in the trade
as central draught lamps I make improvements as follows-
Clause No. 1. I provide a wick holder which is moved upwards & downwards
in a lamp by means of a screw, the wick holder is provided with a top & bottom
plate the top plate being so arranged that it turns upon the bottom plate. Between
the two plates are placed two or more plates having teeth upon them to grasp the
wick, these plates have projections upon them which fit into corresponding slots in
the bottom & top plates or in the top or bottom plate, excentric slots in the top
or bottom plate act upon the toothed plates so that they grasp or release the wick
according as the top plate is moved to the right or to. the left.
Clause No. 2. I use an arrangement consisting of a vertical screw operated upon
by two toothed wheels for the purpose of raising and lowering the wick carriage of
a lamp-the vertical screw arrangement I do not claim as novel but the arrange-
ment for operating it with toothed wheels as shewn in drawing is novel, the
arrangement provides means whereby the screw can be placed nearer the centre of
the lamp and in consequence a longer wick can be used than in ordinary centre
draught lamps.
At the reverse side of the wick holder to that upon which the screw operates I
place an upright shaft C and upon the wick holder a guide working upon the
shaft for the purpose of giving a steady up and down motion to the wick holder.
Diagram No. I refers to Clause No. 1 in it A and A and B and B are plan
C is a
drawing of different forms of wick holder, either of which may be used.
sectional view of a portion of a lamp shewing the wick holder in section. See D D.
Diagram No. 2 refers to Clause No. 2 and is a sectional elevation of a portion of
a lamp. A is the screw which operates wick holder. B. B are the toothed wheels
which turn the screw.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1st. The use of a wick holder substantially as described in Specification and
illustrated in sketch.
2ndly. The use of plates worked by excentric movement from a plate placed
under or over them for the purpose of securing lamp wick in position for use.
3rdly. The use of toothed wheels in connection with vertical screw as shewn in
Diagram No. 2.
