PROVISIONAL SPECIFICATION.
Combined Threshing Machine and Mill, and Improvements in Parts
of same.
I, THOMAS MOORE of Sunderland Street, Tickhill, Yorkshire, Engineer, do
hereby declare the nature of my invention to be as follows :—
My invention relates to the combination of a threshing machine and a grinding
mill, with improvements relating to each of the said machines.
In my invention, the corn after leaving the screen is carriel by means of a screw
to the mill, which is secured to the outside of the frame, and after being ground the
flour is carried by a current of air to the outlet to which the sack is attached.
The mill which may be of ordinary type with perpendicular revolving metal
grinding plates, is driven direct by the axle of the screw feeder, and upon the back
of the running plate are fan blades or vanes enclosed in a casing, and causing a
current of air to be drawn through the grinding plates, which carries the flour
upwards to the outlet which is conveniently placed for bagging.
The beaters of the threshing machine are of improved construction, being much
wider than is usual, and arranged so that they can be reversed in position when
worn, the strength of the beater is increased, and the operation of threshing is
improved by this configuration.
The axle of the beater drum of the threshing machine, instead of running in
ordinary brasses or bearings, I arrange to rest at each end upon the peripheries of
two antifriction wheels, one or both of which as they revolve dip into oil or other
like lubricant held in a special casing or trough.

Combined Threshing Machine and Mill, and Improvements in Parts
of same.
I, THOMAS MOORE of Sunderland Street Tickhill, Yorkshire Engiucer do
hereby declare the nature of this invention and in what manner the same has to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to the combination of a threshing machine and a grinding
mill, with improvements relating to each of the said machines.
The annexed sheets of drawings will illustrate the invention; similar letters of
reference indicate similar parts throughout.

page_text: According to my invention, the corn after leaving the screen in the threshing
machine A, is carried by means of a screw or worm B, to the mill C, which is
secured to the outside of the frame of thresher A, and after being ground the flour
is carried by a current of air to the outlet D, to which the sack is attached.
The mill C, which may be of an ordinary type with perpendicular revolving
grinding plates is driven direct from the shaft of the worm B, and upon the back
of the running-plate E, or immediately behind it I arrange a series of vanes F,
constituting a fan or blower.
These parts namely the fixed plate G, the running plate E, and the vanes F, are
all enclosed in a casing C, and by the action of the revolving vanes, a current of
air is drawn through the grinding plates and carries with it the flour to the outlet
or shoot D, to the end of which the sack is fixed to receive it.
The axle of the beater-drum marked H, in Fig. 4, instead of running in ordinary
brasses and being supported by them, I arrange to rest at each end upon the
peripheries of two antifriction wheels I, and J, one or both of which dip into oil or
other lubricant contained in the casing K, which is thus carried up to the axle H.
N, is a removable collar plate. I am aware that axles are carried upon revolving
rollers and therefore I make no claim to this principle, but only to the particular
arrangement of the several parts.
The beater plates, a diagonal section of which is shown in Fig. 5, are of an
improved construction being made so as to be reversible when worn down at one
edge. The beater plate L, is made wider than usual, and of such configuration
that it constitutes a double beater, each side from the head of the bolt M, to the
edge longitudinally, forming a beater, one being in working position and the other
out of position. When one side is worn, the plate is turned round so as to bring
the opposite side into action.
The beater plates are made with the usual diagonal ribs, and by this double
configuration the operation of grinding is improved and facilitated.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed, I declare that what I
claim, is:-
1. The combination with a threshing machine, of a corn grinding mill, driven
direct from the feed worm which supplies it with corn, and having revolving vanes
arranged to produce a current of air by which the flour is carried to the outlet
shoot, as herein described and set forth.
2. A corn grinding mill of the vertical type such as shown in Fig. 2, of the
drawings, having a number of vanes at the back of the running plate to act as a
blower or fan, as hereinbefore described and shown.
3. In combination with, and as a support for the axle of the beater drum of a
threshing machine, two wheels or rollers supported in a casing with a removable
collar plate, substantially as herein before described and shown.
4. A threshing machine beater plate made with a double working surface, and
capable of being reversed as hereinbefore described and shown.
