WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN LAMPS, WHICH IMPROVEMENTS
ARE PARTLY APPLICABLE TO OTHER VESSELS FOR CONTAINING LIQUIDS." [A com-
munication from abroad by Charles Chinnock and Francis Thill, both of Brooklyn,
New York, United States of America.]
This Invention relates to improvements in lamps, which improvements are partly
applicable to other vessels for containing liquids.
The said Invention comprises a filler cap composed of two parts, one part being
provided at its outer circumference with an annular rim for attachment to a lamp
or other vessel, and having an opening communicating with said vessel, and the
other part consisting of a cover fitting outside the former one, and secured theroto
by a rim bent in an annular rebate or under an annular shoulder, and having an
opening corresponding to that in the part first named, so that upon being turned or
rotated it may cover or uncover the opening in the part first named, so as to
preclude or afford (as desired) access to the vessel to which the cap is applied. The
said cap may be made convex or concave, or, if preferable, the inner part may be
concave, and the outer part convex or flat, providing there is a suitable projection
for closing the opening of the outer part.
The said improved cap may be applied to lamps, bottles, vials, tea and coffee pots,
Baucepans, and other similar vessels.
The said Invention also comprises the combination with a cap of the kind herein-
before described of a burner tube erected thereon, whereby a very serviceable and
convenient lamp burner is produced; and I combine with a lamp burner of the
kind just described a wick-adjusting ratchet wheel arranged in the opening between
the cap and the draught chimney, and preferably supported by lugs extending from
the burner tube, whereby a very simple, cheap, and convenient lamp burner is
produced.

page_text: I further improve the lamp by employing two deflectors of different sizes adapted
to deflect air in the proper quantity and direction to maintain a perfect combustion
of either a large or a small flame, and I combine in a lamp deflectors of different
sizes and an air distributor, a portion or the whole of which may be closed so as to
regulate the quantity of air passing through it.
may also construct an air distributer for a lamp composed of two independent
parts perforated correspondingly, and adapted to be adjusted so that they may be
brought into line, or partly or wholly out of line to admit, regulate, or preclude the
passage of air through them.
I also provide a device for a lamp, comprising the combination of a tubular
portion composing a chimney, a contracted portion forming a deflector, and an
expanded portion, preferably rendered semi-opaque, forming a shade or globe, and
upon the chimney or equivalent device I place a detachable cap or deflector applied
to the tip, so as to preclude currents of air outside the chimney from unfavorably
affecting the flame; and in order to increase the utility of a lamp, I combine a lamp
burner of a size rendering it serviceable for ordinary use with a small lamp burner
of the kind herein-before described, and of a size adapting it to produce a small
flame with a perfect combustion for use through the night in a bedroom or
otherwise.
