Year: 1822

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
NICHOLSON, of Brook Street, Lambeth, in the County of Surry, Civil Engineer,
send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of His United Kingdom, bearing.
date at Westminster, the Sixteenth day of December 1822, in the third year
of His reign, give and grant unto me, the said John Nicholson, my exors,
admors, and assigns, His especial licence, full power, sole privilege and
authority, that I, the said John Nicholson, my exors, adiñors, and assigns,
during the term of years therein mentioned, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN APPARATUS FOR THE MORE CONVENIENTLY
APPLYING HEAT TO CERTAIN INSTRUMENTS OF DOMESTIC USE;" in which said
Letters Patent there is contained a proviso, that if I, the said John Nicholson,
shall not particularly describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in writing
under my
hand and seal, and cause the same to be inrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,,
and all liberties and advantages whatsoever thereby granted, shall utterly
cease, determine, and become void, as in and by the same, relation being there-
unto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Nicholson, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained as follows, that is to say :-
In the Drawings hereunto annexed are represented my apparatus for sup-
plying heat as aforesaid. Figure 1 represents a view of an apparatus for
heating a pair of curling irons for curling hair; and Figure 2 represents a
perpendicular section of the same apparatus. 6, 62, 6, 63, Figs. 1 and 2, is a
cylindrical tube, closed at the bottom at b, for the reception of a pair of curling
irons to be heated. The said tube is supported by the sides a, a, a, a¹, forming
a hollow cone, and continuing downwards perpendicularly at a¹, a³, a¹, a³,
forming a cylinder. e, e, e, e, is a lamp; c represents the conductor of the
wick; 9, 9, 9', g', is a door for taking out and replacing the lamp; c is the
flame of the lamp playing upon the bottom of the tube b, 63, and heating
the same, together with the curling irons intended to be placed therein;
i, i, i, i, &c., are apertures in the perpendicular sides for supplying air to the
flame; and k, k, k, &c. are apertures in the conical sides for allowing a draft to
be formed upwards for the more completely supporting the flame. The same
letters in both Figures 1 and 2 represent the same things, and the dotted lines
in Figure 1 shew the internal parts, supposed to be seen through the sides.
v is a handle for carrying the apparatus about; the whole of the apparatus
constructed of iron, brass, or other fit material. Figure 3 represents an
apparatus for heating an instrument called an Italian iron, for ironing certain
parts of clothing. n, n, n, n, is a hollow conical casing of iron, or brass, or
other fit material, supporting the Italian iron r, r³, and fixed thereto, or made
to shift, as may be deemed necessary, and likewise joined to the base p, p,
forming a foot; w represents the flame of the lamp 0, 0, 0, 0, which receives its
supply of air by means of apertures in the upright sides, as at i, i, in Fig. 1,
and also the draft by means of apertures in the conical sides, similar to k, k, &c.
in Fig. 1; and the said flame plays upon the under surface of the upper side
of the Italian iron, and likewise imparts heat thereto throughout by heating
the air contained therein. The tube b, b, Figures 1 and 2, may be varied in
form, and rendered capable of receiving, for the purpose of being heated, irons
of other forms, such as those used by apothecaries and druggists for spreading
plasters, and those used by wine merchants and others for melting wax on
bottle corks, likewise for irons, commonly called pinching irons, used for ladies'
hair, and a small instrument known by the name of a French iron, used for
ironing certain parts of cloathing; likewise the tube b, b, may be supported
above the lamp in an horizontal or oblique position, or its dimensions, or the

page_text: number of tubes in one apparatus, to receive and afford heat by one or more
lamps may be varied, and the form or construction of the apparatus may also
be otherwise varied, all which variations may be effected by any competent
workman in works of this nature; and that these more forms of the apparatus
are in nowise claimed as my Invention, but the constructing an apparatus
containing a lamp for the purpose of heating the instruments of domestic use
herein mentioned constitutes my Invention.
In witness whereof, I, the said John Nicholson, have hereunto set my
hand and seal, this Fourteenth day of June, in the year of our
Lord One thousand eight hundred and twenty-three.
JOHN (L.S.) NICHOLSON.
AND BE IT REMEMBERED, that on the Fourteenth day of June, in the
year of our Lord 1823, the aforesaid John Nicholson came before our said
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and alf and every thing therein contained and specified, in form above written.
And also the Specification aforesaid was stamped according to the tenor of the
Statute made for that purpose.
Inrolled the Fourteenth day of June, in the year of our Lord One thousand
eight hundred and twenty-three.
