I, WILLIAM. WALTER-GOOD, of Moorgate Street, in the City of London,
Gentleman, do hereby declare the.nature of the said Invention for "IMPROVE-
MENTS IN MACHINES APALICABLE FOR THRASHING AND WINNOWING" to be as follows:-
My said improvements consist in the means I adopt for self-feeding, as
likewise in mechanical arrangements. för facilitating and rendering more
efficacious the thrashing and winnowing processes.
..
In the machines of my Invention I employ a revolver, consisting of a
horizontal shaft carrying serrated metal discs, which are enclosed by a cylinder
formed of zinc plate, with corresponding slots cut in it for the protrusion of
the serrated edges of the discs, by which means the corn will be freely carried
to the drum. A hinged flap or leverage faced with zine is placed before and
beneath the revolver to receive the corn, and by means of this lever it can be
gradually pressed up to the revolver as required.
I further use two setts of concaves, one with rough, the other with smooth
inner edges, and there are bearers to fix the said concaves in, so that they may
be easily and quickly changed. The cross bars of these bearers are supported
by iron rods, the former having an internal screw at each end, and the latter
external screws, so that .the distance of the concaves from the drum may be

page_text: adjusted whilst the machine is in motion, suitable indexes being at the ends of
the cross bars to indicate such adjustment.
The shakers I make with serrated iron plates to divide the straw as it passes
from the machine, so that the corn may be effectually taken from it although
it passes over a less distance than in ordinary machines.
The riddles for my improved machines are also of a peculiar construction.
Two of them are tray-like in form, and perforated zinc plates are placed at a
given distance from the bottom of each, so that the corn, chaff, and broken
ears are separated from the short straws, and as the bottom is closed the corn,
chaff, and short ears are carried to the winnower by one and the same action.
These riddles work from end to end of the machine, so that less racking is
produced by them, and as they open and meet simultaneously there is no
vibration of the machine and driving strap. A small riddle is placed in the
centre of the machine to receive the short straws that fall from the perforated
zinc plates. This small riddle has a cross action to take any corn from the
straw that may not drop through the other riddles; and to carry the short
straws out at an opening in the side of the machine. The chaff may deposit
in a bag outside the machine.
Separate boxes are formed for receiving the broken ears, tail corn, and best
corn as they are divided by the blast from the winnower. And beneath the
box in which the best corn falls is a cylinder, in which a horizontal iron bar
with spikes is placed to revolve for the purpose of taking the awns or beards
off barley, chaff.off wheat, and polishing corn generally.
