Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL'
DESCROIZILLES, of Fenchurch Street, in the City of London, Chemist, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth, did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-fourth day of April, One thousand eight hundred and
thirty, in the eleventh year of His reign, give and grant unto me, the said
Paul Descroizilles, His special licence that I, the said Paul Descroizilles, -
my executors, administrators, and assigns, and such others as I, the said Paul
Descroizilles, my executors, administrators, and assigns, should at any time'
agree with, and no others, from time to time and at all times during the term.
of years therein mentioned, should and lawfully might use, exercise, and
vend, within England, Wales, and Town of Berwick upon Tweed, my Inven-
tion of "CERTAIN IMPROVEMENTS IN APPARATUS FOR ECONOMIZING FUEL IN
HEATING WATER AND AIR, APPLICABLE TO VARIOUS PURPOSES;" in which said
Letters Patent there is contained a proviso that I, the said Paul Des-*
croizilles, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in His
Majesty's High Court of Chancery within six calendar months next .and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance, with the said proviso, I, the said
Paul Descroizilles, 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 in and by the Drawing hereunto annexed, and the
following description thereof (that is to say):
The apparatus of which a description is now to be given may be termed
one possessing extensive surfaces; its essential principle consisting in this
peculiarity, that the fluids to be acted upon may be kept in contact either with
the exterior or interior parts thereof throughout. This principle being pre-
mised, it is obvious that the forms and dimensions of the apparatus may be
varied as circumstances may require. In the Drawing Figures 1, 2, 3, and 4,
represent an apparatus intended to communicate nearly instantaneously a por-
tion of the heat contained in hot waste water produced in establishments for
calico printing, dying, &c., or such as require hot or warm clean water to fresh
clean cold water, in order to lessen as much as possible the consumption of time
and fuel requisite to heat such clean cold water, a circumstance which has
hitherto been unattended to, but which may nevertheless be very advantageous
in manufacturing pursuits. Figure 1. represents à. front view of an apparatus
containing nearly two hundred copper pipes, of from five to six tenths of an inch
in diameter, and about three feet four inches in length, and which are soldered,
into metal plates at their extremities in the order represented by the section,
Figure 2, and at a distance apart of about half an inch from each other. These
pipes are, united or combined in two different receptacles by the two metal,
plates to which they are soldered, the one A, B, C, D, placed above, and the.
other E, F, G, H, below, and into which they communicate at their ends, and
thus form one combination D, A, E, F, G, F, B, C, in Figure 1. The cold
water is to be supplied below at the point y by means of the bent pipe r, s, t,
of about two inches in diameter, and which rises parrallel to the small pipes,
at or about two inches, distance from them, as high as the upper receptacle
A, B, C, D. An apparatus may however be formed of one, two, three, or more
of these combinations, and the number, diameter, and length of the pipes may
be varied as circumstances may require. Figure 3 represents an apparatus con-
sisting of two combinations, intended to employ the waste hot water, and as the
apparatus is to be supplied by a pipe of about two inches in diameter, so the.
orifices of the small pipes must each of them be reduced to about the hundredth
part of that diameter, in order that each small pipe may receive its due supply
of water. Figure 3, as above mentioned, contains two combinations viewed
sideways, d, a, e, h, g, f, v, c, and i, k, l, m, n, o, p, q, with their feeding pipes
r, s, t, and r, s, t. They are placed in a large chest or box I, K, L, M, which

page_text: is divided into two equal parts. by the separation. N, O, which however does.
not reach quite up to the upper part of this chest or box; one of these combi
nations rests against the side I, K, of the chest, and the other, against the
separation N, O, and they are connected together by the double elbowed, pipe,
5 E, F, G, H, furnished with flanches and screws; two other partitions, cach twor
inches in thickness, and the heighth of the chest, and moveable at pleasure, are
affixed by means of grooves made in the chest; these are intended to separate!
the two combinations from their feeding pipes. One of these two separations
is represented in front in Figure 4, A, B, C, D; they are thinned away above
O to the thickness of about the third part of an inch at a, b, c, and d, from fourteen to
fifteen inches in height, and about twenty-eight inches in breadth, and are open at
the bottom at e, f, g, h, to a breadth of twenty-eight inches by eight inches in
. height, and they thus form two additional divisions in the chest, closed; at top
but open
below. All being thus disposed, the apparatus must be placed in the
earth deep enough to receive the warm waste water at the point in Figure 3+
as it escapes from the buildings. This water in passing: through the chest is
forced, by the first;partition u, a, y,, to pass in, contact with the small, metal
pipes a, a, a, &c., and then passing, underneath the said partition it ascends in
contact with the first feeding pipe, and passing, over the top of the partition N, O;
it-is again forced to descend in contact, with the small pipes a,a,a,&c., and
passing underneath the other partition u, x, y, v, it again ascends.in contact
with, the second. feeding pipe of the second combination, and eventually dis-
charges itself at the point X, lower than, the point at which it entered, and
lower than the top of the partition N, O. If the cocks I, K, be shut, and the
cock E be opened, the cold water will proceed directly to the boiler; but if on
the contrary, the cock L be shut, and the cocks I, K, be opened, the cold water
is admitted by the cock K, and passes along the course indicated by the letters
K', t, s, r, through the small pipes a, a, a, &c., and continuing its course through
H, G, F, E, t, 8s, r, and through the small pipes a, a, a, &c. of the second com-
bination, it thence passes between c, d, through the cock I, and escapes at the
end N of the cross pipe, becoming gradually warmed in its passage through
the apparatus by the heat communicated by the warm waste water passing
through the apparatus in the manner before described. If, instead of water,
air be forced through the apparatus by any proper means, the waste hot water
might be made use of to heat that air, and thus to warm such establishments
as require it; for this case, however, the pipes will require to be enlarged. Any
liquors requiring cooling may be passed through the pipes in the apparatus
whilst a current of air is forced through the chest by any proper means,
and will thus cool the liquor contained in or passing through the said pipes.
