and Son, of No. 28, Southampton Buildings, Chancery Lane, in the
County of Middlesex, Patent Agent, for the Invention of "AN IMPROVED
CLARIFYING APPARATUS."-A communication from abroad by Félix Gaudin
and Urbain Sanceau, both of Paris, in the Empire of France.
Sealed the 6th November 1866, and dated the 8th May 1866.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge at
the Office of the Commissioners of Patents, with his Petition, on the
8th May 1866.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,. of No. 23,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN IMPROVED
CLARIFYING APPARATUS," (a communication to me from abroad by Félix
Gaudin and Urbain Sanceau, both of Paris, in the Empire of France, to be as
follows:-
The various parts constituting the improved clarifying apparatus, the
subject of this Iuvention, are illustrated in the accompanying Sheet of
Drawing forming part of this Provisional Specification. From a wooden.

page_text: crown or ring A having a ledge or rebate and supported by three feet B
rises a cylindrical box C made of vulcanized sheet iron, and with a double
bottom. The galvanized cast-iron circles D and D¹ forming these bottoms
are tied together by three or four vertical tie-pieces, and are further pierced
with a certain number of holes, (thirty-seven for a diameter of nineteen
and a half inches,) by which an equal number of vertical filters are introduced,
these filters being composed and placed in the following manner:-To each
hole of the upper circle is soldered a screw-threaded ring E forming a pro-
jection on this circle, and it is on this ring that the cap of the filter F rests.
Soldered to this cap is a spiral iron wire spring G, which unites it to its base H.
This cylindrical and hollow base resting on the lower ring D¹ is terminated by
a screw-threaded tube of less diameter I passing through a corresponding.
hole in the lower circle. The space circumscribed by the spiral spring is
enveloped by a cloth J making two or three turns, and fixed on the cap and the
base of the filter by two straps or bands. The said filter is maintained in this
position, firstly, above by a cover K screw-threaded interiorly, which screws
with the ring above described, and which intercepts all communication with
the outer air by means of a leather washer L; secondly, below by a nut M
which screws on to the tube I, and by means of the washer L³ prevents any
leakage. Beneath the cylindrical box enclosing the filters is placed the
reservoir into which the clarified liquid falls; it fits on a circular band of
galvanized sheet iron N fixed to the wooden crown which serves for support,
and carrying two lugs or pins O diametrically opposed. The said reservoir,
formed like a cylindrical box and also of galvanized sheet iron, carries two
slits P similar to a bayonet slide which permit its being removed and replaced
with facility; the pipe Q serves for the exit of the liquid. A suction
and force pump R draws the thick or troubled liquid from the cask S, forces
it into the interior of the filter box or tubular cylinder, causes it to pass through
the filtering cloths by the equal pressure which it produces in every direction,
and the clarified liquid falls into the reservoir by passing through the vacant
space left by each spiral spring, finally passing into the cask S¹ perfectly. freed
from all the foreign matters which it held in suspension. These foreign bodies
soon attach themselves to the cloths, and form a coating which first aids the
clarification by the tenuity of its pores, but which finishes by becoming too
bard to permit indefinitely the passage of the liquid. The filters must there-
fore be removeable in order that the cleansing of the cloths may be: rapidly
effected, and nothing is more easy, because it is only necessary to remove the
reservoir and unscrew the nut M and the cover K by means of a key with points
entering into the holes T of the said cover. This improved clarifying apparatus

page_text: will in less than an hour perfectly clarify about 830 quarts of wine, beer, or
other liquid.
To move it readily from place to place a carriage may be substituted
in lieu of the fixed stand, but without this change it is not troublesome
to remove the pump by unscrewing the joints U¹, and then to remove the
tubular cylinder by its handles V, thus dividing all the apparatus into three
parts, of a weight easily lifted. The funnel with float ✗ prevents any loss of
lianid.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Gedge in the Great Seal Patent Office on
the 8th November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 28, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of May, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign
did, for Herself, Her heirs and successors, give and grant unto me, the said.
William Edward Gedge, Her special licence that I, the said William Edward
Gedge, my executors, administrators, and assigns, or such others as I, the said
William Edward Gedge, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 "AN IMPROVED CLARIFYING
APPARATUS," (a communication to. me from abroad by Felix Gaudin and
Urbain Sanceau, both of Paris, in the Empire of France,) upon the con-
dition (amongst others) that I, the said William Edward Gedge, my executors
or administrators, by an instrument in writing under my, or their, or one, of,
their hands and seals, should particularly describe 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 William Edward Gedge, do hereby
declare the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by 'the
following statement :-
The various parts constituting the improved clarifying apparatus, the
subject of this. Invention, are illustrated on the accompanying Sheet of
Drawing forming part of this Specification. From a wooden. crown or
ring A having a ledge or rebate, and supported by three feet B, rises a
cylindrical box C made of galvanized sheet iron and with a double, bottom.
The galvanized cast-iron circles D and D¹ forming these bottoms are, tied
together by three or four vertical tie-pieces, and are further pierced with a
→certain number of holes (thirty-seven for a diameter of nineteen and a half
inches), by which an equal number of vertical filters are introduced, these
filters being composed and placed in the following manner :-To each hole of
the upper circle is soldered a screw-threaded ring E forming a projection on
this circle, and it is on this ring that the cap of the filter F rests. Soldered
to this cap is a spiral iron wire spring G, which unites it to its base H.. This
cylindrical and hollow base resting on the lower ring D¹ is terminated by a
screw-threaded tube of less diameter I passing through a corresponding hole
in the lower circle. The space circumscribed by the spiral spring is enveloped
by a cloth J making two or three turns, and fixed on the cap and the base of
the filter by two straps or bands. The said filter is maintained in this position,
firstly, above by a cover K screw-threaded interiorly, which screws with the
ring above described, and which intercepts. all communication with the outer
air by means of a leather washer L; secondly, below by a nut M which screws
ou to the tube 1, and by means of the washer L' prevents any leakage.
Beneath the cylindrical box enclosing the filters is placed the reservoir into
which the clarified liquid fulls; it fits on a circular band of galvanized sheet.
iron N fixed to the wooden crown which serves for support, and carrying two
lugs or pins O diametrically opposed. The said reservoir, formed like a
cylindrical box and also of galvanized sheet iron, carries two slits P similar
to a bayonet slide, which permits its being removed and replaced with facility.
The pipe serves for the exit of the liquid. A suction and force pump R
draws the thick or troubled liquid from the cask S, forces it into the interior
of the filter box or tubular cylinder, causes it to pass through the filtering
cloths by the equal pressure which it produces in every direction, and the.
clarified liquid falls into the reservoir by passing through the vacant space
left by each spiral spring, finally passing into the cask S¹ perfectly freed from
all the foreign matters which it held in suspension. These foreign bodies
soon attach themselves to the cloths, and form a coating which first aids the
clarification by the tenuity of its poles, Lut which finishes by becoming too

page_text: hard to permit indefinitely the passage of the liquid. The filters must
therefore be removeable in order that the cleansing of the cloths may be
rapidly effected, and nothing is more easy, because it is only necessary to
remove the reservoir and unscrew the nut M and the cover K by means of a
key with points entering into the holes T of the said cover: This improved
clarifying apparatus will in less than an hour perfectly clarify about 830
quarts of wine, beer, or other liquid. To move it readily from place to place
or carriage may be substituted in lieu of the fixed stand, but without this
change it is not troublesome to remove the pump by unscrewing the joints U¹,
and then to remove the tubular cylinder by its handles V, thus dividing all
apparatus into three parts of a weight easily lifted. The funnel with
float X prevents any loss of liquid.
the
Having now described the nature of the said Invention, and the manner in
which it is performed, I desire it to be distinctly understood that while
reserving the right of modifying the details of this improved clarifying
apparatus to suit the circumstances of particular cases claim is made to
the exclusive use of all clarifying apparatus constructed and operating
substantially as herein-before described and illustrated on the annexed Sheet
of Drawing.
In witness whereof, I, the said William Edward Gedge, have hereunto
set my hand and seal, this Eighth day of November, in the year
of our Lord One thousand eight hundred and sixty-six.
