PROVISIONAL SPECIFICATION.
Improvements in Spirit Lamps.
We, WILLIAM PEARCE (Junior), Walter Gadd TILLYARD, and FREDERICK
CHARLES ROGERS, trading as Rogers Tillyard & Co., Lamp Manufacturers,
6 Millbank Street, in the City of Westminster, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in spirit lamps and is intended to be
worked in conjunction with the Specification No. 5612 bearing date April 14,
1890.
The object of this invention is to provide a telescopic chimney of talc or
glass with a reflector to the reading lamp for the convenience of travellers.
We construct one or more grooves down the sides of the outer cylinder with
stops at the base, and in these said grooves we slide one or more rings with pro-
jecting pins passing into the grooves. To the ring or rings we fix a chimney and
a reflector of any suitable shape. Between the top and base of the outer cylinder
a hook is hinged for the purpose of attaching the said lamp to persons
garments.
The chimney when required for use slides telescopically upwards and is held in
position by the pins in the ring passing by a slight turn into a bayonet slot formed
in the tops of the grooves in the outer cylinder. The aforesaid chimney descends
to its normal position by forcing the pins out of the bayonet slot and down the
grooves.
It will be understood that the foregoing is given by way of illustration and
that the shapes materials and parts may be varied in many ways within the scope
of our invention.
