I, HENRY FRICKER of 4 Great Portland Street, Oxford Street, London, Manager,
do hereby declare the nature of this invention to be as follows:-
The invention relates to that class of lamps which operate by clockwork to supply a
constant current of fresh air to the burner and dispense with a glass chimney, such
lamps however as at present constructed have a serious fault, which is, that after the
lamp has been in use a short time, the charred wick and oil, is apt to drop down on
the wheel movement (placed under the burner for driving a fan to supply fresh oxygen
to the flame) and so clog it as to stop the motion, which would cause the lamp to
smoke &c. without a chimney.
This device removes the aforesaid objection, and relates to devices whereby the
charred wick and oil will not drop on the wheel movement to stop it, while, at the
same time, a stronger central draft is obtained to the burner.
Second. The device is so arranged and constructed, that all its parts can be easily
seen, and readily repaired if any portion becomes broken, without taking the parts all
to pieces, this is a great advantage, while many other lamps of the same nature have
to be taken all apart to repair some broken or worn out portion, necessitating labour,
skill and expense.
Third. The device can be adapted to use a flat or round wick as desirable, and a
stop-lock will be connected to the fan mechanism, to stop the movement of the wheels
when the lamp is not in use.

page_text: The device consists in a central metal tube preferably of brass placed in the centre
of the lamp, and in a line under the burner, this tube supplies fresh oxygen through
holes around the base of the lamp to the burner, which causes a more powerful light
than without it. On the outside of the said central air tube, a bracket plate is
attached, between which and the tube, the movement wheels and pinions, shafts, &c.
are placed to drive the fan which is at the upper mouth of the central tube, while the
main spring is placed on the outside of the said bracket, with its shaft projecting outside
of the lamp to be in a convenient position to wind it up with a key like a clock to
furnish motive power to drive the wheels, pinions and fan.

1, HENRY FRICKER of 4 Great Portland Street, Oxford Street, London, Manager,
do hereby declare the nature of this invention, which has been communicated to me
from abroad by Richard Mott Wanzer of Hamilton, Ontario, Canada, Manufacturer
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The invention relates to that class of lamps which operate by clock-work to supply
a constant current of fresh air to the burner and dispense with a glass chimney, such
lamps however as at present constructed have a serious fault, which is, that after the
lamp has been in use a short time, the charred wick and oil, is apt to drop down on the
wheel movement, (placed under the burner for driving a fan to supply fresh oxygen to
the flame) and so clog it as to stop the motion, which would cause the lamp to sinoke
&c. without a chimney.
According to the present invention, the aforesaid objection is removed, the charred
wick and oil will not drop on the wheel movement to stop it, and by a clear passage
through the central tube a stronger draft, yet more regular and steady, is obtained to
the burner.
The gear is so arranged and constructed, that all its parts can be easily seen, and
readily repaired if any portion becomes broken, without taking the parts all to pieces,
this is a great advantage, while many other lamps of the same nature have to be taken
all apart to repair some broken or worn out portion, necissitating labour, skill, and
expense.
It is obvious that a flat or round wick lamp can be used as desirable, a stop-lock
being connected to the fan mechanism, to stop the movement of the wheels when the
lamp is not in use.
For the purpose of this invention, a central metal tube preferably of brass is placed
in the centre of the lamp, and in an axial line under the burner; this tube takes fresh
oxygen through holes around the base of the lamp and by means of a fan forces it to
the burner, which causes a more powerful light than without it. On the outside of
the said central air tube, a bracket plate is attached, between which and the tube, the
movement wheels and pinions, shafts, &c. are placed to drive the fan which is at the
upper mouth of the central tube, the main spring being placed on the outside of the
said bracket, with its shaft projecting outside the lamp to be in a convenient position
to wind it up with a key like a clock to furnish motive power to drive the wheels,
pinions and fan.
By reference to the drawing forming part of this specification it will be seen that,
A represents the glass, or it may be metal oil reservoir, surrounded with the outer
casing B, leaving an air space C, between them. D is the lower portion of the lamp
which contains the central air tube, fan, and devices for driving the fan. E is the
central metal tube preferably of brass tubing, affixed to the sides of the lamp by
brackets F. G is the fan placed near the top inside portion of the central air tube E,
it revolves the spindle H which is carried by the bracket 1, and centre cross-piece J.
The lower part of the said spindle is formed with a worm, and a worm wheel K

page_text: attached to the horizontal shaft L, is made to engage with it and so revolve it with
the fan.
The wheel movement for driving the fan is placed outside of the said tube E, and
inside of the bracket plate M, which is secured to the said tube E, and affords bearings
with the tube for carrying the spindles L, N, O, P, with their pinions and movement
wheels, but upon which I do not make any claim as they are the usual clock-
movement.
Qis the spring placed on the shaft P', and made to be easily wound up by the key R,
from the outside of the lamp, for running the wheel-movement and fan.
S, are openings in the base of the lamp to admit air to the central tube E, and
thence through the fan to the spaces C, C, up to the burner T. U is a stop device
employed to stop the fan and wheel movement when the lamp is not burning. W is a
pan for catching any oil droppings or over flow from the burner.
The operation of the lamp may be described as follows; it is first supplied with oil
and wick properly trimmed; the spring Q is then wound up by means of the key R,
which sets the wheels in motion to drive the fan G, which as it revolves rapidly draws
up the air through the central tube E from the openings S at the base, and causes a
continuous upward current of fresh air through the spaces C, to supply the burner
with oxygen without the use of a globe or chimney, the lamp will thus give out a
bright, white flame without smoke or odour, and also be cool, safe, healthy and non-
explosive, and the movement calculated to run for about twenty-four hours, after each
full winding up.
It will further be observed that when a round wick and burner are used, the central
tube E will be connected to the burner by means of an additional tube V through the
oil reservoir A, as shown by dotted lines.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. In combination with a lamp without a chimney, of a central air tube E, the same
enclosing a fan G, driven by wheel movement from outside of said tube E, also the
drip pan W, all substantially as shown on the annexed drawing.
2. In combination with the tube E of the bracket M secured on the outside of the
said tube, by which the spindles of the wheel movement may have their bearings on
tube and bracket, substantially as and for the purpose specified.
3. In combination with the central tube E, fan G, and clock movement on the
outside of tube, of the stop U, substantially as and for the purpose specified.
