Hill at the Office of the. Commissioners of Patents, with their Petition,
on the 24th March 1864.
We, CHARLES GARTON, of the City and. County of Bristol, and THOMAS.
HILL of the Town and County of the Town of Southampton," do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MASHING
APPARATUB," to be as follows!
Our Invention consists in constructing apparatus for mashing in manner
hereafter described, that is to say, "our apparatus consists of an external vessel,
by preference cylindrical, and placed vertically. The vessel is of larger
diameter at the upper part than at the lower, in which the screw blades here-
after mentioned are made to revolve; an inclined ring unites the upper and
lower parts. The lower part of the vessel tapers off towards the bottom,
while the bottom itself is formed with perforations or apertures, which can
be more or less closed according to requirement. In the centre of the bottom
a step or pivot is provided to receive the lower end of a shaft hereafter men-
tioned. Rows of apertures are made in the sides of the vessel, in which the
screw blades work to allow of the insertion of prongs or teeth. A centred
shaft free to revolve at bottom on the stud or in the shoe provided for its
reception, and extending at top above the level of the external vessels, carries
at bottom a wiper, consisting of two arms corresponding with the form of the
tapering end and bottom of the vessel, but free to revolve with the shaft
without touching them; above this wiper the shaft has fixed on it a series of
blades arranged as screw blades, and above them a second wiper, the ends of

page_text: the arms of which are made to taper, and are set on the shaft at such a level
as to revolve within, but without touching the inclined ring herein-before
mentioned. Above this wiper a circular plate or disc, with the edge inclined
downwards, is fixed on the shaft; the shaft is continued upwards, passes
through a collar or bearing, and has fixed to it at top a pulley or other gear
through which rotary motion may be imparted to it. At or above the edge
of the vessel and extending round it is a pipe with perforations, so arranged
as to project the liquid introduced through it to or towards the central shaft,
and above the circular plate thereon. The shaft, with its fittings, having
been introduced into its place, we insert series of teeth or blades, say, four,
through the apertures made in that part of the vessel in which the-screw
blades are placed. Each of these series of teeth is cast or affixed to a bar
with flanges to receive india-rubber or other packing, and the teeth are of
such length and so placed as to enter between the screw blades on the shaft.
After the teeth have been inserted, we keep them in place by means of hoops
or bands tightened up behind the teeth bars. Sometimes we insert a brush
through a slot made for the purpose, in order to cleanse the screw blades.
The shaft is made to revolve. The grain to be mashed is fed into the upper
part of the vessel, and the liquid admitted through the perforated pipe,
meeting it they are.dashed together to the edge of the circular plate, between
which and the inner circumference of the vessel they fall, then down the
inclined ring into the lower vessel, and the mashing is thoroughly effected by
means of the screw and fixed blades; at the same time that all balling and
massing are prevented. The mash issues through the apertures in the
bottom of the apparatus, and is received in a tun or other receptacle.
