page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine, Lake,
& Co., Patent Agents, Southampton Buildings, London, for the Invention of
"IMPROVEMENTS IN AND RELATING TO BURNERS AND CHIMNEYS FOR KEROSENE
LAMPS." A communication from abroad by the Manhattan Burner Company,
of the City and State of New York, United States of America.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 5th June 1879.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO BURNERS
AND CHIMNEYS FOR KEROSENE LAMPS." [A communication from abroad by the
Manhattan Burner Company, of the City and State of New York, United States
of America.]
This Invention relates to lamps for burning kerosene, and comprises a peculiarly
shaped guard or deflector in combination with the usual outer cone, also a peculiarly
shaped chimney and a catch for holding it in place, the chimney being an integral
part of the burner.
The object of the said Invention is to form a guard or deflector to take the place
of the inner cone in order to give a more desirable shape to the flame and produce
a better combustion than has hitherto been attained, and also by the use of a
peculiarly shaped chimney with the same to render the combustion. complete with
much less liability to breakage than heretofore. The object of the improved catch
is to hold the chimney more firmly than is done by those heretofore inade.
In carrying the said Invention into practice the said guard or deflector is con-
structed with straight parallel sides, and with parabolic curved sides, and is placed
underneath the usual outside cone. The said catch is provided with a sliding clasp
which forces it against the chimney; this catch springs away from the chimney and
is forced against it by the said clasp. The parts are in suitable connection with the
base plate. The lower end of the chimney is round at its base, flattened at its
centre, and assumes the round form again at its top. After having tried many
forms of chimney it has been found that this produces the most perfect result.

This Invention relates to a lamp for burning kerosene, and comprises a peculiarly
shaped guard or deflector in combination with the usual outer cone; also a peculiarly
shaped chimney and a catch for holding it in place, the said chimney being an
integral part of the burner.
The chief objects of the said Invention are to form a guard or deflector to take
the place of the inner cone for the purposes of giving a more desirable shape to the
flame and producing a better combustion than has hitherto been obtained; also
by the use of the peculiarly shaped chimney with the said guard to render the
combustion complete, with much less liability to breakage than heretofore. The object
of the improved catch is to hold the said chimney more firmly than is practicable
with those heretofore made.
In the accompanying Drawing,
Figure 1 is a vertical section of an improved burner and other parts constructed
according to this Invention.
Figure 2 is a top view of tho said guard or deflector.
Figure 3 is an elevation of the same shewing its straight and parallel sides.
Figure 4 is an elevation shewing its other sides, which are in the form of
parabolic curves.
A is the guard or deflector; B is the outside cone; C is the chimney; D is the
catch; E is the sliding clasp which forces the said catch against the chimney; a, a,
are the straight and parallel sides of the guard or deflector; b, b, are the sides
thereof that have the parabolic curves. The catch springs away from the chimney
and is forced against it by the clasp E. G is the base plate. The chimney C is
round at its base, is flattened at its centre, and is round at its top. After trial of
many forms of chimney the most perfect result has been obtained with the form
above described.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,
First. The guard or deflector having straight parallel sides and parabolic curved
sides for a kerosene lamp burner, substantially as set forth.
Second. The guard or deflector as described in combination with the cone and
chimney shaped as specified for the purposes set forth.
Third. The catch held against the base of the chimney by the sliding clasp,
substantially as and for the purpose set forth.
Fourth. The combination of the chimney, the conc, and the guard or deflector
with the base plate, substantially as and for the purpose set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set
my hand and seal, this Fifth day of December, in the year of our Lord
One thousand eight hundred and seventy ninc.
