large appear.
NOW KNOW YE, we do hereby describe and ascertain the nature of our
said Invention, and a manner in which the same may be performed, by a
description and Drawing thereof, that is to say :-
That our Invention doth consist in a metalic retort for the purposes of
distillation, evaporation, concentration, or decomposition, so constructed that in
one case, herein-after described, it will resist the action of acids or other
substances upon it, and in the other case, herein-after also described; that an
extension of surface is produced which greatly promotes decomposition. The
first improvement above-mentioned consists in lineing the metalic retort with
Stourbridge bricks or clay, or such other like substances as will resist the
action of acids; and the second improvement above alluded to consists in
introducing shelfs into the retort, as described in the Drawing annexdd.
Figure 1 is a retort, lined with bricks; Figure 2 is a retort, furnished with
shelfs; now these shelfs may be adjusted to any shaped retort, but my im-
provements being confined solely to the lining of the retort with the substances
aforesaid in some cases, and to the introduction of these shelfs in others, I am
desirous to maintain this my exclusive right and privilege to the same.
In witness whereof, I, the said Charles Hunnings Wilkinson, have
hereunto set my hand and seal, the Third day of November, in the year
of our Lord One thousand eight hundred and twenty-one.
