Bicycles and Tricycles.
We PERCY PALMER BURT and SAMUEL BRUCE EDMONDS of Great Charles Street
Birmingham in the County of Warwick Lamp Manufacturers do hereby declare
the nature of the said invention for IMPROVEMENTS IN APPARATUS FOR FIXING
THE WICKS IN LAMPS FOR BICYCLES & TRICYCLES to be as follows:-
This invention refers to apparatus to be applied to that which is employed for
raising and lowering the wick with the view of preventing the wick from dropping
by the vibration of the machine in travelling-Upon the underside of the plate
carrying the wick holder we form a wedge shaped tooth in such position that it
may when in gear engage with the teeth upon one of the toothed wheels upon the
spindle by which the wick, is raised or lowered, when thus in gear, the toothed
wheels cannot revolve and consequently the whick is fixed, when out of gear
which is caused by drawing out the spindle by means of the button outside the
oil cap the wick can be raised or lowered releasing the button, the action of a
spring upon the spindle returns the wheel into gear with the tooth and holds the
wick securely.

We PERCY PALMER BURT and SAMUEL BRUCE EDMONDS of Great Charles Street
Birmingham in the County of Warwick Lamp Manufacturers do hereby declare
'the nature of our said invention for IMPROVEMENTS IN APPARATUS FOR FIXING
THE WICK IN LAMPS FOR BICYCLES AND TRICYCLES and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying drawings and to
the letters and Figures marked thereon :-
This invention refers to apparatus to be applied to that which is employed for
raising and lowering the wicks with the view of preventing the wick from dropping
by vibration or oscillation in travelling.
Upon the underside of the plate carrying the wickholder we form a wedge
shaped tooth in such position that it may when in gear engage with the teeth upon
one of the toothed wheels upon the spindle by which the wick is raised or lowered
when thus in gear the toothed wheels cannot revolve and consequently the wick is
fixed, when out of Gear which is caused by drawing out the spindle by means of
the button outside the oil vessel, the wick can be raised or lowered releasing the
button, the action of a spring upon the spindle returns the wheel into gear, with
the tooth and holds the wick securely.
This arrangement may be applied to carriage and other lamps subject to
vibration and oscillation.
Referring to the accompanying drawings. Fig. 1 is a view shewing our improved
apparatus the parts being in gear. Fig. 2 shews the same parts out of gear.
(a) Fig. 1 is the toothed wheel in gear with the wedge shaped tooth (b) fixexed
upon the underside of the plate which carries the wick holder (c) and bearing
against the wick (d) tightly holding the same and thus preventing it from dropping
by the vibration or oscillation in travelling as the toothed wheel is prevented from
revolving. (a) Fig. 2 is the toothed wheel out of gear with the wedge shaped
tooth (b). It is brought out of gear by drawing out the spindle by means of the
button (e), thus releasing the toothed wheel and enabling the wick to be raised or
lowered at will.
Again releasing the button the action of a spring (ƒ) upon the spindle will
cause the toothed wheel (a) to return into gear with the wedge shaped tooth (b)
and thus hold the wick securely and prevent the possibility of any jar or vibration
causing the wick to run down or drop.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
Firstly. The use of a tooth or projection upon lamps substantially as herein set
forth for the purpose of locking the toothed spindle used for raising and lowering
the wick.
Secondly. The arrangement by which the toothed spindle is thrown into and out
of gear for the purposes set forth and specified.
Thirdly. The general arrangement of parts whereby the wick is prevented from
being affected by vibration or oscillation.
