page_text: CLAYTON'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
CLAYTON, of the City of Dublin, Artist, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Sixteenth day of April, in the fifty-eighth year of His
reign, did, for Himself, His heirs and successors, give and grant unto
me, the said Robert Clayton, my executors, administrators, or assigns,
or such others as I, the said Robert Clayton, my executors, administrators,
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 that part of the
United Kingdom of Great Britain and Ireland called England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "A NEW METHOD OF
DEPOSITING OR INSERTING CERTAIN METALS OR A MIXTURE OF METALS IN WOOD,
IVORY, BONE, HORN, PAPER, AND POTTERY WARE, WHEREBY THE OLD AND TEDIOUS
PROCESS OF INLAYING MAY BE SUPERSEDED, AND THE SAME EFFECTS BE PERMANENTLY
PRODUCED IN A SHORTER TIME AND AT A LESS EXPENCE THAN BY ANY OTHER
PROCESS NOW IN USE;" in which said Letters Patent there is contained a
proviso obliging me, the said Robert Clayton, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
said Invention, and in what manner the same is to be performed, and to
cause the same to be inrolled in His Majesty's High Court of Chancery in
England within six months next and immediately after the date of the said
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
my

page_text: NOW KNOW YE, that in compliance with the said recited provisoe, I,
the said Robert Clayton, do hereby declare that the nature of my Invention,
and the manner in which the same is to be performed, is as follows, viz*:-
I introduce or insert certain metallic substances into wood, ivory, bone,
horn, paper, and other materials, by excavating or indenting the design therein
with knives, chissels, punches, sculpers, or gravers, and employing mixtures of
the fusible metals to cast into and fill up such incissions. For example, I first
trace, print, pencil, or otherwise delineate the design or device on the smooth
surface of the wood, ivory, bone, horn, paper, or other material into which it
is to be introduced, and then proceed to engrave or cut and chisel out the
same to the depth required; and in case the device is delineated on the
surface of wood cut transversely across the grain, I make use of punches
also to assist and more quickly indent the same. Secondly, I pour and rub
into these excavated parts or incisions my metallic fluid, which may consist of
any metal or mixture of metals not liable to tarnish and that is fusible at such
low temperatures, as will not injure the wood, ivory, bone, horn, paper, pottery
ware or other material to be ornamented; such, for instance, are equal weights
of bismuth, tin, and lead, or six parts bismuth, six parts tin, and two parts
'lead, or two parts bismuth, two parts tin, and one of regulus of antimony; but
the mixtures of metals which I use and prefer, consists of four parts of tin to
one part of the regulus of antimony. Lastly, when the metal gets sufficiently
cool'd and set into the design, I proceed to filc, plane off, and polish away
the extra surface metal, and afterwards embellish it with the graver if
required.
The foregoing details are given for the more fully understanding and
illustration of my Invention, and the manner in which the same is to be
performed. But the Invention whereof I claim the sole and exclusive use,
consists in "Casting, Depositing, or Inserting Certain Metals or Mixture of
Metals in Wood, Ivory, Bone, Horn, Paper, and Pottery Ware, whereby the
Old and Tedious Process of Inlaying may be Superseded, and the same
Effects be Permanently Produced in a Shorter Time and at a Less Expence
than by any other Process now in Use," in the manner herein-before
described.
.
In witness whereof, I, the said Robert Clayton, have hereunto set my
hand and seal, the Twenty-first day of September, in the year of
our Lord One thousand eight hundred and eighteen.
ROBERT CLAYTON. (L.S.)
