TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
TAYLOR, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of December, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Josiah
Taylor, Her especial licence, full power, sole privilege and authority, that I,
the said Josiah Taylor, my exors, admors, and assigns, or such others as I, the
said Josiah Taylor, my exors, admors, 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, my
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF LAMPS;" in which said
Letters Patent is contained a proviso, that I, the said Josiah Taylor, 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Josiah Taylor, do hereby declare that the nature of my said Invention, 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 Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say) :-

page_text: My Invention relates to the construction of lamps used for burning fatty
matters and wax, which are not in a liquid state in the ordinary temperatures
of the atmosphere of England, and my Invention relates to the só con-
structing of such lamps as to receive hot water, or pieces of metal of a
cylindrical shape, or solid bars of various sizes, to melt the fatty matters
employed.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
in the various Figures of which the same letters of reference are used to
indicate similar parts.
DESCRIPTION OF THE DRAWING:
Figure 1 shews the upper part of a table lamp; Figure 2 is a section of
the same lamp; Figure 3 shews a plan of the frame for supporting the glass
shade; Figure 4 is a side view of the frame; Figure 5 shows a plan' and-side
view of the tube for turning and raising the wick holder, and within which
the wick is placed. I have not thought it necessary to shew the pillar on to
which the lamp shewn in the Drawing is to be applied; but it should be
observed, that whatever 'be 'the' character of the stand or pillar, that there is to
be a provision for the passage of air to the interior of the flame. a, a, shews
the vessel of the lamp which is to contain the fatty matter, or it may be whx,
which is to be burned. The shape of the vessel'a, a, is clearly shewn in the
Drawing, but the Invention is not confined to a particular shape of the vessel
a, a, so long as it can have the material placed therein melted by
means of
hot water, or pieces of metal so constructed as to apply heat when introduced
into another vessel in combination with the vessel a, a. Below the vessel
a, a, is applied the vessel b, b, as is shewn, and this vessel b,'b, is to receive
hot water (or hot pieces of metal supported by a suitable frame), as shewn in
the Drawing, just before lighting the lamp, the hot water being introduced
through the opening &, or the metal may introduced by taking off the upper
part of the lamp containing the fatty matter. The lamp in other respects is
similar to lamps used for burning oil which is liquid at the 'ordinary tem-
peratures of the atmosphere of 'England, and in fact oil may be burned in such
lamps when there is no supply of fatty matters or wax. d is a tube which
conveys air to the interior of the lamp, there being two projections e, 'e, at the
upper end, which becoming heated by the flame of the lamp, the tube d
conducts the heat, and continues to keep the tallow or other fatty matter
liquid during the time of using the lamp; but in case these projections are
not sufficient to keep up the heat in very cold climates,. I use a circular bar

page_text: of metal, which passes through the flame, the hot water or metal being simply
to melt the matter in the vessel a, a, in the first instance. f is a tube, having
several slits formed therein, as shown at f, f; through these slits the liquid
tallow or other matter flows to the wick, which is placed within the tube f,
and there is also another slit f formed in the tube f, in order to raise: the
wick holder g, such wick holder being of the ordinary construction, it having
a projecting stud'h, which moves up and down in the slit f of the tube f, and
it has also a stud i, which moves in the spiral groove.formed around the tube
d; hence, when the tube f is turned round, the cotton or wick will rise or fall,
according to the direction in which the tube f is turned. On the upper part
of the tube fare affixed three projections j, j, against one of which one of the
arms k of the frame k of the glass shade comes, and when that frame k is
moved round, the tube f will also be moved round, and thus will the wick be
raised or lowered. is the gallery for the glass chimney m; and it will be scen
that the glass chimney has a flange at its lower end, and it is securely affixed
to the gallery by the screw ring n, as is shewn. In using this description
of lamp, the tallow or other fatty matter used should be melted and
poured into the vessel a, a, of the lamp at the opening at a¹; the lamp may
then be put away till it is required for use; indeed the proper time for
supplying the lamp will be after the servant has cleaned it in the morning,
and when the lamp is required for use in the evening hot water or pieces of
heated metal, as described, must be applied.
Having thus described the nature of my Invention, I would remark that
I do not confine myself to the shape of the vessel a and b, nor of the other
parts of the lamp shewn and described, as they may be varied, and I make
no claim to the separate parts of which the lamp is composed, otherwise than
the projections in the spiral for the conducting of heat; but what I claim is,
the mode of constructing lamps for burning tallow, or other fatty matters, or
wax, by combining with the vessel a, a, vessel 6 to receive hot water or heated
pieces of metal, as above described.
In witness whereof, I, the said Josiah Taylor, have hereunto set my hand
and seal, this Third day of June, in the year of our Lord One thousand
eight hundred and forty-two.

presence of
