PROVISIONAL SPECIFICATION.
Improvements in Cycle Lamps.
We, CHARLES ALBERT MILLER, and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street, in the City of Birmingham, Manufacturers,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in the burner part of cycle lamps,
particularly to burners of the duplex or multiple type.
The oil tank, which may form the base to the lamp, has directed up its middle,
an upright air shaft, open at bottom to the atmosphere, and.at top, to the inside.o
the cone.
'
14,
The top of the burner, at parts surrounding the wick casings, is pierced: with
small holes, wherethrough air from the interior of the cone, for promoting combustion
upwardly passes!
J
al
Thus, we may take an ordinary burner, adapted to fit within the mouth or entrance
to the oil tank and with the wick casings, which are placed diagonally and at an
angle, passing through the body of the burner, which is pierced at bottom, and into
which the open top of the air shaft, (which is preferably conical) passing through:
the oil tank, enters.
. !
!!
When the burner is removed, the upper andluarrow end of the air shaft comes
slightly above the plane of the mouth of the tank.
"
It may be observed that the piercings in the cone entirely surround the wick
tubes, so that when the lamp is in use, air for promoting combustion is supplied
upon all sides of the flames.
By our improvements, a better and more luminous light is obtained than is
obtainable with lamps having closed or unpierced cones.
1
Instead of employing two wick casings forming a double burner, three may be
employed, or only one.
The wicks are raised by wick winder stems, arranged either to act independently,
or when required to rise simultaneously by geared-together wick, winders.

We, CHARLES, ALBERT MILLER, and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street, in the City of Birmingham, Manufacturers,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly, described and ascertained in and by the following
statement:
i
Our invention relates to improvements in the burner parts of cycle lamps,.
particularly to burners of the duplex or multiple type.

page_text: The oil tank, which may form thelbase to the lamp, has directed up its middle,
an upright air shaft, open at bottom to the atmosphere, and at top to the inside of
the conc.
The top of the burner, at parts surrounding the wick casings, is pierced with
small holes, wherethrough.air from the interior of the cone, for promoting combustion
upwardly passes.
Thus, we may take an ordinary burner, adapted to fit within the mouth or
entrance to the oil tank and with the wick casings, which are placed diagonally and
at an angle, passing through the body of the burner, which is pierced at bottom,
and into which piercing the open top of the air shaft, (which is preferably conical)
passing through the dil tank, enters.
When the burner is removed, the upper and narrow end of the air shaft may
come slightly above the plane of the mouth of the tank.
It may be observed that the piercings in the cone entirely surround the wick
tubes, so that when the lamp is in use, air for promoting combustion is supplied
upon all sides of the flames.
By our improvements, a better and more luminous light is obtained than is
attainable with lamps have closed or unpierced cones.
Instead of employing two wick casings forming a double burner, three may be
employed, or only one.
The wicks are raised by wick winder stems, arranged either to act independently,
or, when required, to rise simultaneously, by.geared-together wick-winders.
Figure 1 of the accompanying drawing represents, partly in vertical section and
partly in elevation, a cycle lamp provided with improvements in accordance with
our invention.
Figure 2 represents a horizontal section of the same upon the dotted line
looking downwards, and Figure.3 is a like section upon the dotted line '.
Figure 4 is a horizontal section of Figure 1 upon the dotted line x², looking from
the underside up the air shaft.
Figure 5 is an underside plan of the burner when removed from the oil tank
and Figure 5A is an elevation thereof.
Figure 6 is an underside plan of the lamp, showing the air-shaft, which is open
to the atmosphere through the medium of the pierced bottom, in dotted lines.
a is the shell body part of the lamp, having a glazed bell a', crown a²,
breaker a³, all hinged at 6, to the summit of a bracket back plate b², carried by the
combined base and oil tank b, which is fitted with a detachable burner c, having a
pierced crown e', duplex wick casings c², provided with wicks e³, whose upper ends
extend (when in use) above the open ends of the wick casing, whilst their lower
ends hang in the oil within the container.
These wick casings pass through the burner body part c, which has an excentric
opening, upon its underside, wherein the upper open end d', of the vertical air
shaft d, directed through the middle of the oil tank, enters. The lower end of this
said shaft is open to the atmosphere, but is protected from disturbing air currents
by a pierced bottom d².
e are wick winders for raising and lowering the wicks, whilst c is a lip attached
to the burner for facilitating its removal from the opening or socket ³, in the top
of the oil tank.
When the lamp is in use, air for combustion passes through the pierced bottom d²,
and from thence up the air shaft d, through the open top d', and into the interior
of the body ct, of the burner and from thence out through the piercings c', of the
crown c, to the lighted wicks immediately above them.
Instead of the air shaft being vertical and passing from the bottom of the lamp,
it may be directed obliquely or otherwise from any of the sides thereof.
Figure 7 represents a vertical section of the base part of a lamp provided with
improvements in accordance with.a mudification of our invention, in which a direct
vertical air shaft is dispensed with, and holes or piercings in the sides of the body

page_text: of the lamp leading into a chamber or horizontal air shaft in communication with
the interior of a pierced burner, is employed in lieu thereof.
Figure 8 represents an elevation of the lower part of a lamp so provided.
a is the shell body part and b is the oil-tank, having upon the topside of it, a
horizontal air shaft or chamber d, in direct communication with the burner c,
through the interior space or hole d', wherein the said burner fits so that air
passes into the said chamber through piercings d', in the sides and enters the
burner 0, which has piercings c', at the top, through piercings c³, made in the sides
thereof and coming opposite to the annular space d¹.
are the wick casings, which may be duplicate, triplicate, or otherwise and the
sides a', of the lamp come upon the top of the air shaft or chamber d, but do not
overlap the piercings in the sides.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. In the burners of cycle lamps, providing the cones, or the crowns of the
cones, with holes or piercings, substantially as and for the purpose described and
set forth.
Secondly. In cycle lamps, the combination with a burner having a pierced
crown or cone of multiple or single wick-casings together with ventilating hole at
base, substantially as and for the purpose described and set forth.
Thirdly. In cycle lamps, the combination with the burner, of an air shaft,
whose upper
end enters the body of the burner, substantially as and for the purpose
described and set forth.
Fourthly. In the burner and oil tank parts of cycle lamps, the general con-
struction, arrangement and combination of the parts, substantially as and for the
purpose described and set forth in the several figures of the drawings.
