Porter Street, Kingston upon Hull, in the County of York, for the Invention of
"IMPROVEMENTS IN LAMP BURNERS."
PROVISIONAL SPECIFICATION left by the said Walter Peter Cherry and
Charles Edwin Cherry at the Office of the Commissioners of Patents on the
17th February 1879.
WALTER PETER CHERRY and CHARLES EDWIN CHERRY, both of Porter Street,
Kingston upon Hull, in the County of York. "IMPROVEMENTS IN LAMP
BURNERS."
This Invention relates to improvements in the construction and arrangement of
lamp burners having one, two, or three wick tubes, and with removeable slotted
domes, part of which said improvements are also applicable to other burners.
It consists in raising and lowering the wick in burners having one wick tube by
the employment of a toothed wheel rotating on an axis arranged at the side of the
said wick tube, one part of the said toothed wheel projecting at the inside of the
said wick tube, and the other part of the said toothed wheel projecting at the out-
side of the burner case. To raise and lower the wick the thumb or finger is pressed
on the part of the toothed wheel projecting at the outside of the burner case, the
other part of the toothed wheel projecting at the inside of the said wick tube grips
the wick, and thus raises and lowers the same. It also consists in constructing an
hinge to the dome of the burner, so as to prevent the same from being displaced.
In the construction of burners having two wick tubes the toothed wheel rotates
on an axis at the side of each wick tube next to the burner case, and the other part
of the said toothed wheel projecting at the outside of the burner case the wicks are
raised and lowered in precisely the same manner as in the case of the burner having
one wick tube, hereinbefore described. The dome of the said burner is also con-
structed on an hinge in the same manner as the burner having one wick tube. It
also further consists in raising and lowering the wicks in burners having two wick
tubes by means of a toothed wheel mounted on an axis at the outside of each wick
tube next to the case of the burner, which said axis projects at the outside of the
burner case, and is provided with a button to each axis, which serves as a handle for
Pavice 1

page_text: raising or lowering the wicks either simultaneously or separately. The dome of the
said burner is constructed on an hinge in the same manner as the one or two wick
burner hereinbefore described.
In the construction of burners having three wick tubes the toothed wheel rotates
on an axis at the side of each wick tube next to the case of the burner, part of each
toothed wheel projecting at the inside of each wick tube, and with part of each
toothed wheel projecting at the outside of the burner case. To raise and lower the
wicks the thumb or finger is pressed on the part of the toothed wheels projecting at
the outside of the burner case, and the other part of the toothed wheels projecting
at the inside of the wick tubes grips the wicks, and thus raises and lowers the same.
The dome of the burner is constructed on an hinge in the same manner as the one
or two wick burner hereinbefore described.
The toothed wheels which rotate on an axis at the side of the wick tubes with
one part projecting at the inside of the wick tube and one part projecting at the
outside of the burner case, is also applicable to other burners than those berein-
before described; and constructing the dome on an hinge so as to prevent the
same from being displaced is also applicable to other burners than those hereinbefore
described.

Patent Office on the 16th August 1879.
WALTER PETER CHERRY and CHARLES EDWIN CHERRY, both of Porter Street,
Kingston upon Hull, in the County of York. " IMPROVEMENTS IN LAMP
BURNERS."
This Invention relates to improvements in the construction and arrangement of
lamp burners having one, two, or three wick tubes, and with removable slotted
domes, part of which said improvements are also applicable to other burners. It
consists in raising and lowering the wick in burners having one wick tube by the
employment of a toothed wheel rotating on an axis arranged at the side of the said
wick tube, one part of the said toothed wheel projecting at the inside of the said
wick tube, and the other part of the said toothed wheel projecting at the outside
of the burner case. To raise and lower the wick the thumb or finger is pressed
on the part of the toothed wheel projecting at the outside of the burner case, the
other part of the toothed wheel projecting at the inside of the said wick tube grips
the wick, thus raises and lowers the same. In the construction of burners having
two wick tubes the toothed wheel rotates on an axis at the side of each wick tube
next to the burner case, and the other part of the said toothed wheel projecting at
the outside of the burner case the wicks are raised and lowered in precisely the samo
manner as in the case of the burner having one wick tube, hereinbefore described.
It also further consists in raising and lowering the wicks in burners having two
wick tubes by means of an toothed wheel mounted on an axis at the outside of each
wick tube next to the case of the burner, which said axis projects at the outside of
the burner case, and is provided with a button to each axis, which serves as a
handle for raising or lowering the wicks either simultaneously or separately. In
the construction of burners having three wick tubes the toothed wheel rotates on
an axis at the side of each wick tube next to the case of the burner, part of each
toothed wheel projecting at the inside of each wick tube, and with part of each
toothed wheel projecting at the outside of the burner case. To raise and lower the
wicks the thumb or finger is pressed on the part of the toothed wheels projecting
at the outside of the burner case, and the other part of the toothed wheels pro-
jecting at the inside of the wick tubes grips the wicks, and thus raises and lowers
the same.
The toothed wheels which.rotate on an axis at the side of the wick tubes with
one part projecting at the inside of the wick tube and one part projecting at the
outside of the burner case, is also applicable to other burners than those hereinbefore
described.
And in order that our said Invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF DRAWINGS.
Fig. 1 shews side view in section of a lamp burner constructed according to our
Invention, having one wick tube and a tube for holding a stationary wick, and
with the toothed wheel arranged at the side of the said wick tube for raising or
lowering the wick; Fig. 2 shews side view in section of a lamp burner, having two
wick tubes, and with the toothed wheels arranged at the side of each wick tube
for raising or lowering the wicks; Fig. 3 shews a side view of a lamp burner,
having three wick tubes, and with the toothed wheels arranged at the side of each
wick tube for raising or lowering the wicks; Fig. 4 shews a side view in section of
a lamp burner, having one wick tube, and with the toothed wheel arranged at the
side of the wick tube for raising or lowering the wick; Fig. 5 shows a plan of the

August, in the year of our Lord One thousand eight hundred and seventy
nine.
