PROVISIONAL SPECIFICATION.
Improvements in Oil Lamps.
WILLIAM HENRY WATHEN 259 Bishop Street Birmingham Brassfounder, do hereby
declare the nature of this invention to be as follows:-
My invention consists of the construction and arrangement of parts hereinafter
described for preventing the wick rising or sliding down the wick holder from the
level at which it is required & placed. My improvements are applicable to all kinds
of Oil Lamps, but especially to railway carriage roof lamps, and are as follows:-
I fix against the ordinary wick holder an additional frame or compartment marked A
on Fig. 1 on Drawing herewith, this frame has slots pierced in the side the same as
the ordinary wick case and is fixed so that the slots are opposite those in the wick
case. Inside this frame or compartment I place a fork, or toothed rack, the teeth of
the same being placed opposite the apertures in frame before mentioned, see Fig. 2
on Drawing herewith. The bar or axle of toothed rack marked B on Fig. 3 on
Drawing herewith is placed in the semi-circular part marked C of additional frame
before mentioned so that the teeth will pass freely either through the slots in the
wick case, or back through the slots in the additional frame before mentioned.
I will now proceed to describe the action of the parts hereinbefore mentioned :-
In threading the wick in the case the centre tooth of rack before described being
made heavy causes the rack to swivel and fall back, thus allowing the wick to pass in
the case freely, either up or down, see Fig. 4 on Drawing herewith.
When the wick holder is placed in the burner case, as will be seen in Fig. 5 on
Drawing herewith the teeth of said rack are forced by the burner case through the
slots before mentioned and press against the wick and so keep it from rising or
falling. I prefer to make the centre tooth heavier than the others but do not bind
myself to do so, neither to the number or form of teeth used.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
WILLIAM HENRY WATHEN Brassfounder 259 Bishop Street Birmingham 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:-
My invention consists of the construction and arrangement of parts hereinafter
described for preventing the wick rising or sliding down the wick holder from the
level at which it is required and placed. My improvements are applicable to all
kinds of Oil Lamps, but especially to railway carriage roof lamps, and are as
follows I fix against the ordinary wick holder an additional frame or compartment
marked A in Fig. 1 on Drawing herewith, this frame has slots pierced in the side the
same as the ordinary wick case and is fixed so that the slots are opposite those in the
wick case.
Inside this frame or compartiment I place a fork or toothed rack,
the teeth of the same being placed opposite the apertures in frame before mentioned,
see Fig. 2 on Drawing herewith.
The bar or axle of toothed rack marked B. on Fig. 3 on Drawing herewith is placed
in the semi-circular part marked C of additional frame before mentioned so that the
teeth will pass freely either through the slots in the wick case, or back through the
slots in the additional frame before mentioned. The toothed rack may also be used
without the whole additional frame or compartment, by being fixed against the

page_text: ordinary wick holder by using the semi-circular or socket parts of additional frame
hefore mentioned & marked C. I will now proceed to describe the action of the parts
bereinbefore mentioned..
In threading the wick in the case the centre tooth of rack before described being
made heavy causes the rack to swivel in the socket parts and fall back thus allowing
the wick to pass in the case freely either up or down, see Fig. 4 on Drawing here-
with. When the wick holder is placed in the burner case, as will be seen in Fig. 5
on Drawing herewith the teeth of rack are forced by the burner case through the
slots before mentioned and press against the wick, and so keep it from rising or
falling. I prefer to make the centre tooth heavier than the others but do not bind
myself to do so, neither to the number of teeth, their form or the form of any of the
parts used.
The Drawings herein referred to are those left with the Provisional Specification.
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 1
claim is,
The means of preventing the wick rising or sliding down the wick holder from the
level at which it is required and placed, by means of a fork, or toothed rack herein-
before described and made to swivel so that when the wick holder is placed in the
burner case, the teeth of fork or rack hereinbefore described press against the wick
and hold it in the required position.
Dated this 8th day of March 1890.'
