PROVISIONAL SPECIFICATION left by the said Anthony Gapper Southby
at the Office of the Commissioners of Patents on the 7th November 1876.
ANTHONY GAPPER SOUTHBY, of Three, New Inn, Strand, in the County of
Middlesex, Civil Engineer. "IMPROVEMENTS IN AUTOMATIC MASHING MACHINES
FOR BREWERS AND DISTILLERS."
I use for the purpose of mixing the liquours and the grist in the operation of
mashing, as required by brewers and distillers, a rectangular pipe set perpendicularly
and open at its lower end, and I let the grist fall into its upper end in one or more
rectangular streams of about the width of one of the sides of the pipe in one
direction, but of a regulated thickness in the other direction, as specified further on.
I allow the mashing liquour to flow into the pipe in a number of more or less
borizontal jets, so as to strike the falling stream or streams of grist at or nearly at'
right angles on plan to the wider side.
I regulate the thickness of the stream or streams of grist to the power of the
jets of liquour, so that the jets of liquour shall force their way right through the
thickness of the stream or streams of grist, or if the jets are on both sides of the
stream or streams of grist thay may only force their way fully half-way through
the thickness of the stream or streams of grist.
I place the jets in a row or rows horizontally across the pipe, and if more than
one, I place the rows as close together as convenient, alternating the jets perpen
dicularly.
When more than one stream of grist is used I place a pipe containing the row or
rows of jets between each of the streams of grist.
I place the jets in the row or rows sufficiently near together that collectively they
may act on the whole of the falling stream or streams of grist, and I sometimes
make the alternating jets in the row or rows of different strengths, so that while
one jet may pierce right through or fully half-way through the the stream or streams
of grist the alternating jet may pierce a shorter distance into the stream of grist.
[Price 6d.]

page_text: I prefer to make the jets in the thickness of a plate or plates of metal, the
thickness being not less than twice the diameter of the nozzle of the jet, and I make
the nozzle conical and to the shape producing the greatest momentum of the issuing
jet commensurate with the head of liquour.
I regulate the stream or streams of grist as it or thay fall into the top of the pipe
by slides or trapdoors, and in either case I sometimes make them double, so as to
keep the stream of grist central between the opposite rows of jets of liquour, and I
connect the double slides or trapdoors so that thay may be actuated together; as
for instance, by a right-and-left screw, or by a screw acting on levers fixed to the
axes of the trapdoors, or by tooth wheels geered together and to the slides, or
joined to the axes of the trapdoors, and in the same way if more than one stream
of grist is to be regulated the slides may be made after the manner called hit or
miss, or the trapdoors be increased in number and actuated simultaneously, as
described for single pairs.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Anthony Gapper Southby in the Great Seal Patent Office on the 30th
April 1877.
ANTHONY GAPPER SOUTHBY, of Three, New Inn, in the County of Middlesex, Civil
Engineer. "IMPROVEMENTS IN AUTOMATIC MASHING MACHINES FOR BREWERS AND
DISTILLERS.".
I use for the purpose of mixing the liquor and grist in the operation of mashing
as required by brewers and distillers, a rectangular pipe set perpendicularly and
open at its lower end, and I let the grist fall into its upper end in one or more
rectangular streams of about the width of one of the sides of the pipe in one
direction, but of a regulated thickness in the other direction, as specified further on.
I allow the mashing liquor to flow into the pipe in a number of more or less
horizontal jets, so as to strike the falling stream or streams of grist at or nearly at
right angles on plan to the wider side.
I regulate the thickness of the stream or streams of grist to the power of the
jets of liquor, so that the jets of liquor shall force their way right through the
thickness of the stream or streams of grist, or if the jets are on both sides of the
stream or streams of grist they may only force their way fully half-way through
the thickness of the stream or streams of grist.
I place the jets in a row or rows horizontally across the pipe, and if more than
one I place the rows as close together as convenient, alternating the jets perpen-
dicularly.
When more than one stream stream of grist is used I place a pipe containing
the row or rows of jets between each of the streams of grist.
I place the jets in the row or rows sufficiently near together that collectively they
may act on the whole of the falling stream or streams of grist, and I sometimes
make the alternating jets in the row or rows of different strengths, so that while
one jet may pierce right through or fully half-way through the stream or streams of
grist the alternating jet may pierce a shorter distance into the stream of grist.
I prefer to make the jets in the thickness of a plate or plates of metal, the
thickness being not less than twice the diameters of the nozzles of the jets, and I
make the nozzles conical and to the shape producing the greatest momentum of the
issuing jet commensurate with the head of liquour.
I regulate the stream or streams of grist as it or thay fall into the top of the pipe
by slides or trapdoors, and in either case I sometimes make them double, so as to
keep the stream of grist central between the opposite rows of jets of liquour, and I
connect the double slides or trapdoors so that thay may be actuated together; as
for instance, by a right-and-left screw, or by a screw acting on levers fixed to the

page_text: axes of the trapdoors, or by tooth wheels geered together and to the slides, or
joined to the axes of the trapdoors; and in the same way, if more than one stream
of grist is to be regulated the slides may be made after the manner called hit or miss,
or the trapdoors be increased in number and actuated simultaneously, as described
for single pairs.
In the annexed Drawings a, a, are the rectangular pipes, the first A being that of
a machine with a single stream of grist regulated by the trapdoors C geered
together and acted on by a double row of jets of liquor b, b', on each side of the
stream; the second A¹ being that of a machine with two streams of grist regulated
by hit-or-niss slides actuated by the right-and left screw g; E being the centre
pipe between the streams; f is the bottom of the hopper, from which the stream of
grist flows; d, d, are the pipes conducting the liquor to the outer jets.
In these machines the upper and lower rows b, b', are shewn of different
diameters, and for the heads of liquor usual in breweries and distilleries the upper
and stronger rows of jets may be made of a diameter of 3/16ths of an inch, the lower
and weaker jets being 1/8th inch, while the thickness of the stream or streams of
grist may be about 2 inches.
"
In working these machines liquor of the proper temperature is first turned on to
the jets, and the grist is then let on by opening the trapdoors or slides, and
regulated to the desired thickness by the spring lever handle h, or the handle of the
right-and-left screw i, and the cock or valve j.
Having thus described and ascertained the nature of my Invention, and in what
manner the same is to be performed, and having illustrated by Drawings two of
the formes of apparatus.
In witness whereof, I, the said Anthony Gapper Southby, have hereunto set
my hand and seal, this Thirtieth day of April, in the year of our Lord
1877.
