I, JAMES FRY, of Chesham, in the County of Buckingham, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MASHING MACHINERY USED IN MAKING FERMENTED LIQUORS," to be as follows:-
To regulate and indicate the supply of malt in and to mashing machinery
I use a tubular machine, supplying the same with liquor through pipes fixed in
the mash tun, and from thence through a coil of pipe placed round the tube of
the machine, and I place a thermometer between the supply tap and the
entrance of the liquor to the machine; and I also attach the supply tap and
slide to governors or other mechanism so as to regulate the supply of liquor,
and raise and fall the slide or valve to any variation that may occur in the
speed of the driving power, the slide or valve being that placed at the end of
the machine to increase or diminish the. action of the rakes or blades, as
herein-after described. I purpose to regulate the supply of malt, and to
discharge it before the rakes as they traverse the mash tun. In some cases I
should use the same regulating apparatus as described for tubular machines,
and discharge the malt before the rakes. I fix shoots in number in pro-
portion to the diameter of the rakes over which the disc or travelling "board
revolves, closing all others and leaving a passage open, and conveying malt to
the one pointing to the rakes, and this disc or travelling board so continues to
revolve with the speed of the rakes, the malt falling before them as they

worm or other mechanism to draw the malt from the centre of the mash tun
and distribute it before the rakes. I also purpose attaching supply tap gover-
nors, as in the former case, to regulate the supply of liquor to the machine to
the speed of the driving power. Further, I use a fluted, corrugated, or ribbed
roller, or a roller with boards, prejections, or rakes; this roller works in a box
or case, which has hinged thereto a regulating flap or board, which can be
adjusted by means of an adjusting screw or mechanism, so as to regulate the
amount of malt desired to be delivered to the mashing machinery, and by
marking the adjusting screw the indicating will be attained; or this may be
effected through the intervention of gearing acting on an indicator dial at the
bottom or near to the bottom of the regulating machine. A slanting piece
may be provided to be inserted into the mouth of the mashing machinery to
prevent back action upon the malt and liquor. The mashing machinery I
prefer to make with a longer tube than as ordnarily practised, and placed
perpendicularly, though the horizontal position could be adapted with the
revolving rake working therein; and instead of one tube and rake I can
connect several tubes and rakes, so as to communicate with each other and
form a complete and compact system of mashing machinery; and I also
purpose jacketting these tubes with steam or hot air, gas or vapour jacketting,
using a thermometer or other indicator for convenience of the operator, I
also prefer to use an octagonal instead of a square shaft or spindle revolving
within the tube provided with blades instead of rakes, and this will enable
rakes or blades to be fixed inside the tube to act as cleaners.
