Improved Wick Adjusting Device for Oil Carriage Lamps.
I, ALFRED BILLENS, of 71 Cathedral Square, Christchurch, in the Provincial
District of Canterbury, in the Colony of New Zealand, Lamp-manufacturer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described in and by the following statement :-
This invention relates to the class of oil lamps which are used in carriage lamps
and the like originally intended to employ candles and has for its object the
provision of a wick adjusting device which will not be in the way when the lamp
is inserted in the candle socket of an ordinary carriage lamp while it will be
readily accessible for operation within the lantern thereof.
In my invention the wick is carried in a tube and a carrier partially surrounding
the wick is operated by a stem which projects upwardly through the lamp and has
an adjustable handle hinged or pivoted upon it.
Referring to the accompanying drawings in which similar letters of reference
indicate the same parts throughout the figures.
Fig. 1 is a section of a carriage lamp candle socket carrying a lamp fitted with
my invention.
Fig. 2 a vertical central section of the lamp.
Fig. 3 a plan thereof.
Fig. 4 a side elevation of the wick tube showing the adjusting device.
Fig. 5 a side elevation of the adjusting device.
Fig. 6 a section on line 6-6 Fig. 4.
Fig. 7 a section on line 7-7 Fig. 4, and
Fig. 8 a side elevation and plan of a packing washer.
The oil lamp (a) is made in the usual manner to take the place of a candle and
to fit within the candle socket (6) of a carriage lamp as shown in Fig. 1.
The wick tube (c) is approximately rectangular in section and formed with a
long opening or slot (d) to permit the carrier (e) which slides within the tube and
partially surrounds the wick; to be operated by a stem (f) which is fixed to the
carrier at one end and has the handle (9) hinged upon it at the other.
The upper part of the lamp is provided with a projecting lip (4) upon which
rests a washer (i) of leather or other material having a hole to receive the
stem (/).
The washer (k) which has a slot (k¹) to receive the stem (f) is fixed upon the
wick tube and a gland (1) screwed into the cap in the top of the lamp bears against
the washer and holds the tube in position.
The holes in the washer (i) and (k) are large enough to permit the hinged joint
of the handle to pass through and the stem (f) is increased in size at its upper
end so as to fit the hole in the washer (i) and prevent the escape of oil when the
lamp is laid upon its sides.
In operation before placing the lamp within the socket the handle is turned up
so as to clear the hole (m) in the bottom of the lantern of the carriage lamp, after
the lamp is in position and the wick adjusted by the handle, the latter may be
turned down (as shown in dotted lines in Fig. 1) so as to be away from the heat of
the flame and to rest upon the top of the lamp socket to prevent the wick from
jolting down.

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 :-
1. The wick adjusting device consisting of the combination with the lamp (a) of
the wick tube (c) the carrier (e) the adjusting stem (f) having a hinged handle (g)
substantially as and for the purposes herein specified and illustrated.
2. The hinged handle upon the wick adjusting stem which can be turned up to
allow the lamp to be placed within a carriage lamp socket and then turned down
to be away from the wick and for adjusting purposes substantially as specified
and illustrated.
Dated this 28th day of September 1896.
