page_text: LETTERS PATENT to Frederick Charles McQueen, of Longfield Villa, Uxbridge
Road, Shepherd's Bush, in the County of Middlesex, for the Invention of "IM-
PROVEMENTS IN LAMPS FOR THE BURNING OF PARAFFIN AND OTHER OILS."
Sealed the 20th October 1877, and dated the 27th April 1877.
PROVISIONAL SPECIFICATION left by the said Frederick Charles McQueen
at the Office of the Commissioners of Patents on the 27th April 1877.
FREDERICK CHARLES MCQUEEN, of Longfield Villa, Uxbridge Road, Shepherd's
Bush, in the County of Middlesex. "IMPROVEMENTS IN LAMPS FOR THE BURNING
OF PARAFFIN AND OTHER OILS."
The object of the Invention is when using several wicks in the same lamp to
facilitate the use if desired of only one, or of some of them, whilst the others are at
rest, and to enable the user to give motion to one or some of a series independently
of the others, and at other times to give motion to all of them simultaneously by
one operation. For this purpose the axes of the spur wheels by which the
respective wicks are raised or lowered are each provided with a separate pinion, and
these pinions are operated for their rotary motion by other pinions on a separate
axis, such pinions on this separate axis being arranged and applied so that by
sliding such separate axis endwise the desired changes may be obtained. Thus,
supposing there to be three wicks, and it be desired for a time to use only the
centre one, then a tooth wheel on the separate axis will be moved to gear only with
the tooth wheel on the axis which by its spurs or teeth gives the desired lifting or
lowering motion to the centre wick; or supposing it is desired to use for a time only
the two outside wicks, then the centre wick will be moved down out of the way
and the pinion on the separate axis which operated the pinion on the spur shaft to
the centre wick tube will be moved out of the way of that pinion, and another
pinion on that separate shaft will be brought into position to operate on the pinions
of the spur shafts to the outer wick tubes, so as for the time only to operate those
wicks, or supposing it to be desired simultaneously to use all the wicks, then the
separate shaft will be slided so that the spur gear thereon will simultaneously
operate all the wicks. Stops hold the separate shaft in the respective positions.
In like manner may other number of wick tubes be employed.

page_text: The wick or wicks at any time not desired to be used should, before lighting the
other or others, be turned down out of the way of ignition.
The outer wick tubes are formed to turn outwards on hinge joints to facilitate
removal or replacement of the wicks, and they are held in correct relative position
for use by a clip or holder, and the spur and separate shafts are held to position for
ready removal when required for repair or otherwise by a bar or frame, and one or
more pins, studs, or screws.
The gallery for the glass is separate from the cone, and placed a short distance
therefrom, so as to admit of a current of air between them.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Frederick Charles McQueen in the Great Seal Patent Office on the
24th October 1877.
FREDERICK CHARLES MOQUEEN, of Longfield Villa, Uxbridge Road, Shepherd's

The object of the Invention is when using several wicks in the same lamp to
facilitate the use, if desired, of only one, or of some of them, whilst the others are at
rest, and to enable the user to give motion to one or some of a series independently
of the others, and at other times to give motion to all of them simultaneously by

wicks are raised or lowered are each provided with a separate pinion, and those
pinions are operated for their rotary motion by other pinions on a separate axis,
such pinions on this separate axis being arranged and applied so that by sliding
such separate axis endwise the desired changes may be obtained. Thus, supposing
there to be three wicks, and it be desired for a time to use only the centre one, then
a tooth wheel on the separate axis will be moved to gear only with the tooth wheel
on the axis, which by its spurs or teeth gives the desired lifting or lowering motion
to the centre wick, or supposing it is desired to use for a time only the two outside
wicks, then the centre wick will be moved down out of the way, and the pinion
on the separate axis which operated the pinion on the spur shaft to the centre wick
tube will be moved out of the way of that pinion, and another pinion on that
separate shaft will be brought into position to operate on the pinions of the spur
shafts to the outer wick tubes, as for the time only to operate those wicks; or
supposing it to be desired simultaneously to use all the wicks, then the separate
shaft will be slided so that the spur gear thereon will simultaneously operate all the
wicks. Stops hold the separate shaft in the respective positions. In like manner
may other number of wick tubes be employed.
The wick or wicks at any time not desired to be used should, before lighting the
other or others, be turned down out of the way of ignition.
But that the Invention may be more fully understood, I will, by the aid of the
accompanying Drawing, proceed to describe means pursued by me in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents parts of the head of a lamp arranged according to my
Invention.
Figure 2 represents another sectional view of parts taken in a direction trans-
versely of Figure 1; Figure 3 is an external view, and Figures 4 and 5 are upper
and under side views of the same.
In each of the views the same letters indicate corresponding parts.
a, b, and c are three wick tubes, and d, e, and fare the axes on which are applied
the respective spur wheels d, e¹, and f¹, the teeth of which by acting on the

page_text: respective wicks act to raise or lower them as required. These axes d, e, and ƒ are
supported to revolve freely in stationary bearings, as shown, and they have also
applied to them the pinions d³, e², and f³ The teeth of the pinions d² and e³ are in
position to be taken into simultaneously by the teeth of the pinion g affixed on the
shaft h, on which is also affixed another pinion i. The shaft h is supported with
capability of endway movement in bearings h¹, and the pinions d², e, f, g and i
are applied on their respective shafts, so that at one time the teeth of the wheel g.
may as shown be taking into the teeth of the wheels d³ and e³ whilst the teeth of
the wheel i are taking into the teeth of the pinion f2, so that by turning the shaft h
the three wicks in the respective wick tubes a, b, and c, may be simultaneously
operated in the direction desired, and the shaft h is capable of being held in this
position by means of the sliding stop j, or by sliding the stop j downwards out of
the way of the shaft h that shaft may be moved inwards, so that whilst the teeth
of the wheel g still gear with the teeth of the wheels d² and e' to simultaneously
operate the wicks carried by the two tubes a and b, the wheel i is moved to a
position such that its teeth miss those of the wheel f' when the wick in the tube c
is not required to be used; or by sliding the shaft h fully in the opposite direction
the wheel g will be moved to a position between the wheels d², e², and f' whilst the
teeth of the wheel i are in gear with the teeth of the wheel f3, by which the wicks
in the tubes a and b will remain at rest, whilst that in the tube c alone will be
capable of movement. Thus it will be seen that by these arrangements all three
wicks may be used together, or only one, or some of them.
The tubes to the wicks not for the time in use may be covered by caps, indicated
by dotted lines q in Figure 1, and separately at Figures 6 and 7, or otherwise. I is
the cone, and m the glass; n represents by dotted line part of the reservoir for the
oil for the time to be consumed. The surface o is perforated with numerous small
holes, whilst the part p is lined with wire gauze or formed with fine holes to regulate
the draught.
The outer wick tubes may, if desired, be formed to turn outwards, or hinge joints
at a, b, to facilitate removal or replacement of the wicks, and the wick tubes aro
then held in correct relative position at their upper ends for use by a clip or holder
embracing them. The shaft e would then be capable of ready removal, and be held
in position by one or more pins, studs, or screws holding the parts of the bearings
together.
The gallery for the glass may be separate from the cone 7, as indicated by the
dotted lines r, Figure 1.
The glass is supported at a short distance from the cone 1, so as to admit of a
current of air through the holes l¹.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, I would have it understood that I do not confine myself to the
precise arrangements of parts as shewn and described, as the same may be varied
without departing from the peculiar character of the Invention, but what I do claim
is the arranging or combining parts of lamps for the burning of paraffin and other
oils, whereby with several wick tubes facility is afforded for the use at any one
time of only one, or some, or all of such wicks as may be required, substantially as
described.
In witness whereof, I, the said Frederick Charles McQueen, have hereunto set
my hand and seal, this Twentieth day of October, in the year of our Lord
Witness,
ALFRED G. BROOKES.
