Year: 1828

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
DAKIN PHILP, of Regent Street, Saint James', in the County of Middlesex,
Chemist, send grecting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-ninth day of November, in the ninth year of
His reign, did, for Himself, His heirs and successors, give and grant unto
me, the said Edward Dakin Philp, His especial licence that I, tho said
Edward Dakin Philp, my executors, administrators, and assigns, or such
others as I, the said Edward Dakin Philp, my exors, adЛiors, 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 "AN IMPROVED DISTILLING AND
RECTIFYING APPARATUS;" in which said Letters Patent is contained a proviso
obliging me, the said Edward Dakin Philp, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed,
and to cause the same to be enrolled in His said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of

page_text: the said 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
Edward Dakin Philp, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are particularly
described and ascertained in and by the Drawing annexed to this Specification,
and the following description thereof (that is to say):-
In the said Drawing, Figure 1 is an external view or elevation of the
body of a still, set in brickwork in the usual manner, to the neck of which
still I have adapted my said improved distilling and rectifying apparatus, and
which consists of four sets of vessels, formed in copper or other fit and
proper material or materials, although I can employ more or fewer of
them as occasion may require. The external parts of these vessels A, A, &c.
constitute so many water baths, as shown at A in Figures 2, 3, 4, and 6.
Figure 2 is a vertical section of the apparatus, in which B, B, &c.,
represent four metal cylinders flanged to the bottoms of the four water
baths A, A, &c., and open at top. From the internal part of the metal
plate forming the bottom of each water bath descends a short tube
C, C, &c., shown in Figures 2, 4, and 6, and within each cylinder
B, B, &c. an inverted cylinder D, D, &c. is placed, so as to be removeable at
pleasure. The lower edge of each of these inverted cylinders D, D, &c. is
formed into feet or supports, either by cutting away the metal between them,
as here shown at E, E, &c., or by affixing feet to them; and the metal plates
forming their tops have each of them two apertures or openings made in them,
as shown at F, F, &c. and G, G, &c. Around and above the openings F, F, &c.,
metal tubes, I, II, &c., are affixed, and beneath the other openings G, G, &c.
other metal tubes I, I, &c., are likewise affixed. The tubes H, HI, &c. are
also surrounded with other cylindrical tubes I, I, &c., which are firmly united
to the said metal plates, so as to be capable of containing water within the
space enclosed between the tubes II, II, &c. and J, J, &c. The inverted
cylinders are placed within the cylinders B, B, &c., as shown in the section
Figure 2, and are connected with each other by the descending tubes I, I, &c.
passing through the tubes C, C, &c. of the cylinders B, B, &c. over the tubes
II, II, &c., and descending into the water contained in the spaces between the
tubes J, J, &c. and H, H, &c. Each of the cylinders B, B, &c. are flanched
and screwed together, as shewn in Figure 1. From the bottom of the lowest
cylinder B, which is immediately over the body of the still, a tube K descends,
as shown in Figure 2, and reaches within about two inches of the still bottom;
and also upon the said bottom are affixed two tubes J and H, similar to those

above mentioned, shown in Figure 5.. To the top of the uppermost cylinder-B
a metal plate L is affixed, having an aperture in.it from which a short, tube M.
descends, as shewn in Figure 8.and in the plan Fig. 9. This tube M.passes
over the tube H, affixed upon the top of the uppermost inverted cylinder D,
Figure 2, and descends into the water which is, contained between the tubes
I and H. There is also flanched upon the top of the uppermost external
cylinder B:a dome N, with a curved pipe or tube O proceeding from it to the
worm of the still, as shown in Figure 1.;. The water in the several water baths
A, A, &c. is supplied by a pipe P, furnished with a cock Q, as shown in
Figure 2, and which delivers it into the uppermost water bath A, near to its
bottom, and from whence it flows down the pipes R, R, &c. in succession to
the others below, and finally escapes by the cock S. T, T, &c., Figure 1, are
iron brackets, the lower ones of which rest upon the brickwork of the furnace
of the still, and the others are united to the water baths, so. as to.support.and
take their weight from off the body of the still. U is a manhole and plate for
purpose of cleansing the still. The alcoholic vapour passes up from, the
still through the tubes H and I, shown in Figure 2, into the upper part of the
first or lowermost metal cylinder B, from whence it is compelled to return
down between the inverted cylinder D and the water bath A, where a separation
takes place between the aqueous and the alcoholic parts of the vapour, the
aqueous part, being condensed, flows down through the tube K to the bottom
affthe still, whilst the alcoholic part enters the bottom of the inverted cylinder D,
through the apertures E, E, &c., and ascends up the tubes H and I into tho
upper part of the next cylinder B, where another separation of the aqueous
and alcoholic parts of the vapour again takes place, and which process is in
like: manner repeated in the two other successive vessels and inverted cylinders,
and the alcohol becoming more and more pure at length passes up through
the short tube. Minto the dome N, and finally through the curved pipe or
tube O to the worm, as shown in Figure 1. The aqueous part of the vapour,
which is condensed in all the vessels except the lowermost one, flows down
between the tubes C and I, and, mingling with the water contained in the
spaces between the tubes H, H, &c. and J, J, &c., flows over the tops
of the tubes J, J, &c. into the successivo lower vessels, and finally passes down
the pipe K into the bottom of the still. These water joints not only afford
a facility of combining the various series of cylinders with each other without
making them fixtures, but also assist in the separation of the aqueous and
alcoholic parts of the vapour, in consequence of their surrounding the tubes
through which the vapour passes upwards, and which said water joints are
continually filled up or supplied with the condensed aqueous part of the
