CERTAIN IM- PROVEMENTS IN APPARATUS TO BE EMPLOYED FOR THE PURPOSES OF COOLING AND EVAPORATING
Year: 1857

page_text: LETTERS PATENT to Edward Mucklow, of Bury, in the County of
Lancaster, Manufacturing Chemist, for the Invention of "CERTAIN IM-
PROVEMENTS IN APPARATUS TO BE EMPLOYED FOR THE PURPOSES OF COOLING
AND EVAPORATING."
Sealed the 25th August 1857, and dated the 27th February 1857.
PROVISIONAL SPECIFICATION left by the said Edward Mucklow at the
Office of the Commissioners of Patents, with his Petition, on the.
27th February 1857.
I, EDWARD MUCKLOW, of Bury, in the County of Lancaster, Manufacturing
Chemist, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN APPARATUS TO BE EMPLOYED FOR THE PURPOSES OF COOLING AND
EVAPORATING," to be as follows:-
My improvements are designed for the purpose of cooling such liquids as:
require to be evaporated, whilst at or below a boiling temperature, particu- ..
larly sugar dye extracts and other liquids requiring to be evaporated at a low
temperature. Above the vat or cistern containing the liquor to be evaporated,
is placed a wince, or roller or rollers according to the size of the vat; upon
these rollers are placed endless bands of cloth which hang into the vat nearly
touching the bottom, the outer surfaces of which are doubled or ridged, and
lags of wood, &c. having inward bevilled surfaces forming a kind of bucket, aro
secured on cach side of the doubles or ridges from selvedge to selvedge of the

page_text: cloth, so that when a rotatory motion is given to the rollers the lagged cloth
will raise the hot liquid from the cistern or vat, and after exposing it to the
nir to cool return it again to the vat after passing over the wince or roller. A
similar effect may be obtained by causing a wheel or wheels having buckets
attached to their peripheries or sides to revolve in the vat (immersed about to
the axis), so as to take up the liquid, expose it to cool, and return it again
into the vat, or by many other well known mechanical equivalents.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Mucklow in the Great Seal Patent Office on the
27th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
MUCKLOW, of Bury, in the County. of Lancaster, Manufacturing Chemist,
sond greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of February, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, tho
said Edward Mucklow, Her especial license that I, the said Edward Mucklow,
my executors, administrators, and assigns, or such others as I, the said Edward
Mucklow, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN APPA-
RATUS TO BE EMPLOYED FOR THE PURPOSES OF COOLING AND EVAPORATING," upon
the condition, amongst others, that I, the said Edward Mucklow, by an
instrument in writing under my hand. and seal, should particularly describo
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Mucklow, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say:-
My improvements are designed for the purposes of cooling such liquids as

page_text: require to be evaporated, whilst at or below a boiling temperature, particularly
sugar dye extracts and other liquids requiring to be evaporated at a low tem-
perature. Above the vat or cistern containing the liquor to be evaporated, is
placed a wince or roller or rollers according to the size of the vat; upon those
rollers are placed endless bands of cloth which hang down into the vat nearly
touching the bottom, the outer surfaces of which are doubled or ridged, and
lags or ribs of wood, &c. having inward bevilled or concave surfaces forming
a kind of bucket, are..secured on each side of the doubles or ridges from
selvedge of the cloth, so that when a rotatory motion is given to the rollers
the lagged cloth will raise the hot liquid from the cistern or vat, and after
exposing it to the air to cool return it again to the vat after passing over the
wince or roller. A similar effect will be obtained by causing a wheel or
wheels having buckets attached to their peripheries to revolve in the vat
(immersed about to the axis, so as to take up the liquid, expose it to cool,
and return it again into the vat, or by many other well known mechanical
equivalents.
In order that my Invention may be better understood, I have hereunto
attached a Sheet of Drawings made upon a scale of about one inch and a
half to a foot, and having similar letters of referenco marked upon corre-
sponding parts of the apparatus.
Fig. 1 is a sectional elevation shewing the endless cloth and lagged surface,
and also the beating pipes; Fig. 2 is an end view of the same.. In Fig. 1,
a, a, is the vat or cistern, at the bottom of which are the pipes b, b, for keep-
ing the liquor heated; c is the roller placed in adjustable bearings, over which
the cloth d passes, and by means of which motion is given to the cloth; c, e,
are the lags or ribs of wood, &c. upon the external surface of the cloth; theso
ribs have their upper surfaces (when proceeding in the direction of the
arrows) bevelled inwards, or of a hollowed or concave form, in order to take
up the liquid as buckets; thus it will be readily seen that motion being given
to the roller c, it will be imparted to the cloth d, which hanging into the
liquid will cause the ribs or buckets c, e, to raise and a portion of such
liquid into the air to cool, and return it and empty the buckets as the cloth
passes down on the opposite. In the employment of this novel contrivance I
prefer to fill the vat or cistern with liquid only to about the depth of a foot,
and allow the cloth nearly to touch the heating pipes, as I find the time
required in process of cooling and evaporating to be considerably diminished
thereby.
Having now described the nature of my said Invention together with the
manner of performing the same, I would remark, in conclusion, that I claim

page_text: the novel employment, application, and use of an endless cloth or other
suitable equivalent, having ribs, folds, lags, or buckets formed upon its external
surface for the purpose of taking up liquid to be cooled and evaporated as
herein-before described, set forth, and fully exhibited in the Drawings
attached.
In witness whereof, I, the said Edward Mucklow, have hereunto set my
hand and seal, this Twenty-sixth day of August, in the year of our
Lord One thousand eight hundred and fifty-seven.
EWP MUCKLOW. (L.8.)
