A NEW COMBINATION OF MATERIALS FOR THE MANUFACTURE OF CRUCIBLES, MELTING POTS, AND FIRE BRICKS
Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SPINNEY, of Cheltenham, in the County of Gloucester, Gas Engineer, send
greeting.
WHEREAS His most Excellent Majesty King William the Fourth, by
His Royal Letters Patent, bearing date at Westminster, the Eleventh day
of May, in the third year of His reign, and in the year of our Lord One
thousand eight hundred and thirty-three, did give and grant unto me, the said
Thomas Spinney, my exors, adñiors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said Thomas Spinney, my exors,
admors, and assigns, by myself and themselves, and by my and their deputy
or deputies, servants or agents, or such others as I, the said Thomas Spinney,
my exors, adñiors, 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 use, exercise, and vend my Invention of "A NEW
COMBINATION OF MATERIALS FOR THE MANUFACTURE OF CRUCIBLES, MELTING POTS,
AND FIRE BRICKS," and all other benefit and advantage thereof, within that
part of His Majesty's United Kingdom of Great Britain and Ireland called
England, the Dominion of Wales, and the Town of Berwick-upon-Tweed, in
such manner as to me, the said Thomas Spinney, my exors, adñiors, or assigns,
should seem meet, and that I, the said Thomas Spinney, my exors, admors,
and assigns, should and lawfully might have and enjoy the whole profit, bene-
fit, commodity, and advantage from time to time coming, growing, accruing,
and arising by reason of the said Invention, for and during the term of four-
teen years therein mentioned; in which said Letters Patent is contained a

page_text: proviso that if I, the said Thomas Spinney, should 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 after the date of the now reciting Letters
Patent, that then the said Letters Patent, and all liberties and advantages
whatsoever thereby granted, should utterly cease, determine, and become
void, anything therein-before contained to the contrary thereof in anywise not-
withstanding, as in and by the said Letters Patent, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Spinney, do hereby declare that my said Invention of a New Com-
bination of Materials for the Manufacture of Crucibles, Melting Pots, and Fire
Bricks, consists in the combination of the following well-known materials,
videlicit, fire clay, as Stourbridge fire clay, sand (which I recommend to be as
free from lime as possible), and pipe clay. The proportions in which these
materials are used may be as follows, videlicit:-Of Stourbridge fire clay,
twenty parts; burnt fire clay, four parts; of sand, eight parts; and of pipe
clay or potter's clay, four parts; that is, estimating the several parts by weight.
But I should observe, that very great nicety in the proportions is not essential,
as I have found that the proportions may be varied and yet a beneficial result
obtained. The pipe or potter's clay must be thoroughly dried and ground fine;
it is then to be mixed with the fire clay and sand, and as much water added
as will make the whole mass of such a consistence as will admit of its being
tempered and afterwards burnt in the usual manner.
I do not mean or intend to limit myself to the Stourbridge fire clay, but to
avail myself of any other clay which may be fit for the purpose; neither do I
limit myself to the exact proportions of any of the materials above set forth,
which, I have already said, may be varied; what I claim as my Invention being
essentially the combination of clay, sand, and pipe clay for the manufacture of
crucibles, melting pots, and fire bricks.
In witness whereof, I, the said Thomas Spinney, have hereunto set my
hand and seal, this Eleventh day of November, in the year of our
Lord One thousand eight hundred and thirty-three.
Signed, sealed, and delivered (being
first duly stamped), in the pre-
sence of
THOMAS (L.s.) SPINNEY.
H. J. NEILD,
King St., London.
