page_text: CLARKE'S SPECIFICATION.
TO ALL. TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
MILLER CLARKE, of Albany Street, Regent's Park, in the County of Middlesex,
Patent Night Light Manufacturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her.
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Third day of March, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said.
George Miller Clarke, Her especial licence, full power, sole privilege and
authority, that I, the said George Miller Clarke, my exors, admors, and
assigns, or such others as I, the said George Miller Clarke, my exors,
adfors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF LAMPS, AND APPARATUS TO BE USED THEREWITH,"
communicated to me by a certain Foreigner residing abroad; in which said
Letters Patent is contained. a proviso that I, the said George Miller Clarke,
shall cause a particular description of the nature of the said Invention, and in-
what manner the same is to be performed, to be inrolled in Her said Majesty's.
High Court of. Chancery within six calendar months next and immediately
after the date of the said in part recited. Letters Patent, as in and by the same,
reference being thereunto had; will more fully and at large appear:;
:

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Gourge Miller Clarke, do hereby declare that the nature of the caid Inven
tion, and the manner in which the same is to be performed, are fully.
described and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, and to the figures and letters

tion, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, and to the figures and letters
marked thereon (that is to say) :-
The Invention relates,
First, to the construction of lamps especially adapted to the burning of
those matters (such as ordinary tallow or cocoa-nut oil) which are hard at the
usual temperature of the atmosphere.
Secondly, the Invention relates to the arrangement of the parts of a lamp to
be used as a night light and for other purposes.
But in order that the Invention may be fully understood and readily carried
into effect, I will proceed to describe-the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a section, and Figure 2 is a plan of a lamp constructed
according to the Invention; and Figure 3 shows some of the parts separately.
a is the glass vessel or reservoir containing the fatty or oily matter to be
burned; and it will be seen that this vessel a is formed flat on the under side,
with a well or descending part a¹ in the centre thereof. This part a' serves to
receive the lower part of the wick tubes, wick, and parts connected therewith,
and admits of the supply of matter to be burned being kept near to the upper
part of the wick; also it allows of the reservoir being readily applied to or
removed from the pedestal, as occasion may require, for cleaning or other-
wise, there being a socket 6 screwed into the top of the pedestal, to receive the
well part a¹ of the reservoir a, as shewn. It will be seen by reference to the
Drawing now under description that the upper part or cover a of the vessel a
is formed separately from the lower parts a, a', thereby allowing of those.
parts a, a', being more readily moulded or otherwise formed; and the part a²
is secured to the part a by plaster of Paris, or other suitable cement may be
used. a', a³, are notches in the centre opening of the cover a, by which the
parts forming the burner are adjusted in the vessel ȧ, and prevents turning
round when the wick is being raised or lowered. And the parts of the
burner are so formed as that the air to supply the exterior as well as the
interior of the flame passes down the parts of the burner previous to its
coming in contact with the flame, whereby the air becomes to a certain
extent heated, producing a more brilliant flame than when the air coming in
contact with the flame is in a cold state, as is the case with the present:

page_text: arrangement of burners. c is the inner air tube, which is affixed at its lower
end to the plate c'; the plate c' is secured to the tube d, and it is between
the tube c and d that the wick is controlled to move, as I will presently.
proceed to describe. The tube d is secured to the tube e by the projections a'
in such manner as that the air passing through the apertures e¹ in the tube e,
may be allowed to descend to the inner tube, and upwards to the outside of
the flame, as indicated by the arrows. On the tube e is formed the flange f;
by which the tube e is secured to the tube g; and the tube 9 has a flange gl
on its upper edge, which rests upon the aperture in the cover a³, while the
projections pass into the notches a³, a³. On the tube c is formed a rib c¹,
which, passing into a slit in the wick holder or bucket h, controls the same to
rise vertically, and the wick holder is raised and lowered by the tube i, which
has a spiral groove formed thereon, which receives the spiral projection h¹
on the wick holder h, whereby, as the wick holder is prevented by the ribs
from turning round, the wick holder will be raised or lowered according to
the direction in which the tube i is turned, and the tube i is turned by the
frame j, which supports the glasses, the part of the frame being formed to
receive the projection e' on the tube e, thereby preventing the frame j from
rising excepting when the notches are brought opposite the projections e²,
and the part j¹ prevents the air passing through those parts, and as
much as possible controls it passing through the aperture e¹, e¹; and the
projections on the tube i are received between the openirs. Tho
chimney is retained on the framej by the screws j³, as shown. The arms
jconnect the parts j₁ to the ring j", and support the glass shade, as is.clearly
shown in the Drawing.
Fig. 3 shows the cover a² separately.
Figures 4, 5, & 6 show an arrangement of lamp according to this part
of the Invention, suitable for burning flat wicks. In these Figures similar
letters are used to indicate similar parts, and the way in which the air is
conducted to the flame is indicated by the arrows. In this case the wicks are
raised or lowered by the axes 1, 1, aided by the endless bands passing over such
axes & over the axes, ; these axes have projecting surfaces ',, which
pass into and assist in raising the wick.
Figures 7, 8, & 9 represent views of a lamp constructed according to the
second part of the Invention. A is the oil vessel, which is inverted when it
is necessary to place a fresh supply therein, the foot B which sustains the
wick tube being secured to the vessel A by the screw joint, as shown, there
being a leather washer to keep the parts close. C is the wick tube with holes
to admit any pointed instrument to raise the wick, as is common for such

page_text: wicks. D, D, are holes to admit air to the flame. And it will be seen by
this arrangement of oil vessel, that whatever be the quantity of oil therein,
such oil will always be retained about the same level with respect to
the wick.
. Having thus described the nature of the Invention communicated to me, I
would have it understood that I do not confine myself to the precise details
herein described, so long as the peculiar character of either part of the
Invention be retained. But what I'claim is,-
First, the mode of arranging the parts of a lamp whereby the air passing
to the exterior as well as the interior of the flanie is caused to descend into
and thereby become heated by the parts of the burner previous to its coming
in contact with the flame, as herein described. And I also claim the mode
of forming glass reservoirs of lamps with a cover, as herein described. And
I also claim the mode of forming reservoirs of lamps with a well, as herein
described.
Secondly, I claim the mode of arranging the parts of a lamp, whereby the
oil is retained at a uniform level with respect to the wick, as described with
respect to Figures 7, 8, & 9.
In witness whereof, I, the said George Miller Clarke, have hereunto set
my hand and seal, this 29th day of August, in the year of our Lord
One thousand eight hundred and forty-five.
GEORGE MILLER (L.s.) CLARKE.
