CHARLES CLINCH, of 31, Pynes Terrace, Saint David's Hill, Exeter, in the
County of Devon, and of Saint Anne's Well Brewery, Exeter. "IMPROVEMENTS IN
APPARATUS TO BE USED IN BREWING AND IN COOLING AND HEATING LIQUORS."
This Invention has for its object improvements in apparatus to be used in
brewing and in cooling and heating liquors.
Within a vat or vessel containing liquor to be cooled or heated I arrange an
upright cylinder or drum closed at the ends, and with a large number of tubes of
small diameter traversing it from end to end. The liquor in the vat or vessel
enters these tubes, and the space in the cylinder or drum around the tubes is
supplied either with cold water or with steam, according as it is desired to cool or
to heat the liquor.
I arrange a screw propeller beneath the bottom of the cylinder or drum it is
carried upon, an axis passing down through the centre thereof. The axis is driven
in any convenient way, and the screw is thus caused to propel the liquor either
upwards or downwards according to the direction in which the screw is rotated.
In this way the liquor is "roused" or made to circulate in the vat or vessel.
Whon the circulation is in an upward direction at the sides of the vat or vessel,
the direction is downward through the tubes of the apparatus; or by reversing
the motion of the propellor the circulation may be made to take place in the
contrary direction. In order to render the screw propeller more effective in
producing a movement of the liquor past it in a vertical direction either upwards
or downwards I provide it with a band or hoop around its blades, and about of the
same depth as the blades.

page_text: The propeller is about of the same diameter as the cylinder or drum of the
apparatus, and is placed immediately beneath the bottom thereof.
This apparatus is especially useful in attemperating wort during the process of
fermentation, that is to say, in preventing any undue rise in temperature, and at
the same time "rousing" the liquor to maintain an uniform and sufficiently active
fermentation. When the apparatus is thus used cold water is admitted by a pipe
to the lower part of the cylinder or drum, and is drawn off from the upper part
thereof, whilst by the rotation of the propeller a circulation of the liquor is
maintained in a downward direction through the tubes.
When used in this way the apparatus serves as a combined attemperator and
rouser.
Where a sufficient head is available the warmed water passing away from
the cylinder or drum may actuate an hydraulic motor by which the propeller
is driven.
In cases where it is desired to heat or boil the liquor contained within the vat
or vessel, the interior of the cylinder or drum is supplied with steam from a boiler,
and the condensed water is drawn off from the bottom.
The liquor may if necessary be first boiled and then cooled in the same vat or
vessel by supplying the cylinder or drum first with steam and afterwards with cold
water.
The apparatus when thus used serves as a combined boiler and cooler or
refrigerator.

CHARLES CLINCH, of 31, Pynes Terrace, Saint David's Hill, Exeter, in the
County of Devon, and of Saint Anne's Well Brewery, Exeter. * IMPROVEMENTS IN
APPARATUS TO BE USED IN BREWING AND IN COOLING AND HEATING LIQUORS."
This Invention has for its object improvements in apparatus to be used in
brewing and in cooling and heating liquors.
Within a vat or vessel containing liquor to be cooled or heated I arrange an
upright cylinder or drum closed at the ends, and with a large number of tubes of
small diameter traversing it from end to end. The liquor in the vat or vessel
enters these tubes, and the space in the cylinder or drum around the tubes is
supplied either with cold water or with steam according as it is desired to cool or
to heat the liquor. I arrange a screw propellor beneath the bottom of the cylinder
or drum it is carried upon, an axis passing down through the centre thereof. The
axis is driven in any convenient way, and the screw is thus caused to propel the
liquor either upwards or downwards according to the direction in which the screw
is rotated. In this way the liquor is "roused" or made to circulate in the vat or
vessel.
When the circulation is in an upward direction at the sides of the vat or vessel
the direction is downward through the tubes of the apparatus; or by reversing
the motion of the propellor the circulation may be made to take place in the
contrary direction. In order to render the screw propellor more effective in
producing a movement of the liquor past it in a vertical direction either upwards
or downwards I provide it with a band or hoop around its blades, and about of
the same depth as the blades.
The propeller is about of the same diameter as the cylinder or drum of the
apparatus, and is placed immediately beneath the bottom thereof.
This apparatus is especially useful in attemperating wort during the process of
fermentation, that is to say, in preventing any undue rise in temperature, and at
the same time "rousing" the liquor to maintain an uniform and sufficiently active
fermentation. When the apparatus is thus used cold water is admitted by a pipe
to the lower part of the cylinder or drum, and is drawn off from the upper part
thereof, whilst by the rotation of the propeller a circulation of the liquor is
maintained in a downward direction through the tubes.
When used in this way the apparatus serves as a combined attemperator and
rouser.
Where a sufficient head is available the warmed water passing away from the
cylinder or drum may actuate an hydraulic motor by which the propellor is
driven.
In cases where it is desired to heat or boil the liquor contained within the
vat or vessel, the interior of the cylinder or drum is supplied with steam from a
boiler, and the condensed water is drawn off from the bottom.
The liquor may if necessary be first boiled and then cooled in the same vat or
vessel by supplying the cylinder or drum first with steam and afterwards with cold
water.
The apparatus when thus used serves as a combined boiler and cooler or
refrigerator.
The Drawing hereunto annexed shews an elevation partly in section of apparatus
arranged as above described.

page_text: A is the vat or vessel containing the liquor to be cooled or heated; B is the
upright cylindrical outer casing of the attemperator; C, C, are the tubes passed
through the casing B and through the ends by which it is closed at top and bottom';
D, D, are tubes by which water or steam can be admitted into the interior of the
casing B; E is an outlet by which water can be allowed to pass off from the
casing; F is the screw propeller placed below the bottom of the casing B, and
carried by an axis G which rises up through the centre of the casing B, and turns
in a bearing carried by a cross timber K at the top of the vat or vessel A. Above
this timber it has a band wheel upon it by which it can be revolved; H is the
vertical hoop or band placed around the circumference of the screw propeller to
render it more effective in producing an upward or downward movement of the
liquor; I is a stand upon which the cylindrical casing B is carried; J is a water
wheel driven by the stream of water passing away from the attemperator or from
any other supply wherever a sufficient head of water is available. From the axis
of this wheel motion is transmitted to an axis J', and from it to the axis G of the
propeller, or other means may be adopted for driving the axis G.
Having thus described the nature of my Invention, and the manner of performing
the same, I would have it understood that I claim as my improvements in apparatus
to be used in brewing and in cooling and heating liquors.
First. The combination of the vat A, vertical attemperator B, and screw
propeller C placed below the bottom of the attemperator for forcing or drawing.
the liquor through the attemperator tubes, substantially as described.
Second. The combination with the screw propeller F of a cylindrical hoop or band
of approximately the same diameter as the attemperator casing B.
Third. The combination of apparatus substantially as herein before described
and shewn in the Drawing annexed.
In witness whereof, I, the said Charles Clinch, have hereunto set my hand
and seal, this Twenty second day of September, in the year of our Lord
One thousand eight hundred and eighty-one.
