Majesty's Colonies and Plantations abroad, my Invention of "AN IMPROVED
THRESHING MACHINE;" in which said Letters Patent is contained a proviso that
I, the said Joseph Pryor, shall cause a particular description of the nature

fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Pryor, do hereby declare that the following is a full and particular
Specification of the nature of my said Invention, and the manner in which
the same is to be performed, reference being had to the Drawings hereunto
annexed; that is to say:-.
Figure 1 is a plan, and Figure 2 a side elevation (partly in section), of my
said Improved Threshing Machine.. A, A, is a strong wooden frame standing
on four legs, or otherwise supported in a substantial manner. b, b, is an axle
laying across the frame and working in suitable bearings, having keyed
on to it at one end a fly wheel C, and at the other end a spur wheel D.
Outside of these wheels, at the two extremities of the axle, there are two
winch handles e, f, by which the machine is worked, which may be by hand,
or any other convenient mover. A second axis, laying parallel with the
former and similarly mounted, carries a pinion G, which gears into the spur
wheel D, and also a wooden drum H, from the periphery of which project
eight or any other convenient number of angular iron beaters h. This drum
H has a moveable case or covering over its upper circumference, with an
opening in front, through which the grain is supplied to the machine from
the feeding table I. Below the feeding table there is a sliding rack, having
a concave wooden surface corresponding to the outer circumference of the
drum and beaters, upon which surface a series of angular iron plates k, k, are
fixed. This rack slides backward and forward upon a bearer stepped into the
frame of the machine, its distance from the drum H being regulated by an
adjusting screw L, which works through a fixed nut m in the cross rail of the
fráme. A rapid motion being communicated to the drum, and the corn fed
in at the aperture i, it is carried down under the drum, and the seeds beaten
out from the straw by the action of the beaters h, h, and the rack.k, k, and
in a separated state at the hinder part of the machine.
escape
And having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that I do not claim any one
of the parts of the said Improved Threshing Machine as being in and of itself
altogether new; but that I claim the general arrangement and combination
of parts of which the said machine is made up, and by which a new and
improved mode of operation is introduced.
In witness whereof, I have hereunto set my hand and seal, this Twenty-
1L and fontro one
JOSEPH (L.S.) PRYOR.
