page_text: The several Drawings hereunder delineated, marked Fig. 1, 2, 3, are so many
sections, in which are displayed the nature and use of the machinery for the
more effectually working and mashing of malt, and such other articles as are
worked or mashed by brewers, distillers, and others of similar trades, in tuns
or vessels usually called mash tuns, the particulars of which they consist being
as follows

page_text: Is an addition to the machine, to be fixed to the horizontal shaft G in
Figure 1, by which it may work by hand, which operates in manner following:
The horse moves the purchase wheel (C), which turns the halt head (D) on
the horizontal shaft (G), on which is fixed the trundle head (E) and the
spurr
nutt (F). The trundle head (E) turns the horizontal wheel (K) with the
arm (S) on the saddle (L), and four friction wheels (M, M, M, M), to the
left round the main shaft (H, H), to carry eight oars round the tun (X).
And the spur nutt (F) turns the top wheel (I), fixt on the main shaft (H,H),
which turns the check wheel (O), turns the spur wheel (P), which turns
up the eight oars (Q, Q, Q, Q, Q), fixed to the shaft (R), passing through
the spur wheel fixt upon the centre of that shaft, and that shaft fixed into
the hollow cylinder (T), round the iron spindle at the one end, and into the
arm (S) at the other end. The spur wheel traverses round the tun, and the
goods are thereby from the oars effectually mashed, so that every part of
their strength is compleatly extracted. The ropes (N) lead to pullies that
are for the convenience of lifting up the check wheel (0), to permit the
grinding of the malt into the tun and the taking out of the goods. The
bolts (W) are to fasten it down when at work, and the bolt for the hole (Y)
is to keep up the check wheel when the machine does not work. The main
shaft fixes to a beam of the brewhouse at the top, and to the cheese by its
spindle at the bottom.
In witness whereof, I, the said James Walker, have hereunto put my hand
and seal, the Fourth day of July, in the twenty-seventh year of the
reign of our Sovereign Lord George the Third, by the grace of God of
Great Britain, France, and Ireland King, Defender of the Faith, and
so forth, and in the year of our Lord One thousand seven hundred and
eighty-seven.
