PROVISIONAL SPECIFICATION.
Improvements in or connected with Thrashing Machines.
I, WILLIAM MCKENZIE, Managing Director of the Firm of Thomas
McKenzie and Sons Limited of 212 Great Brunswick Street in the City and
County of Dublin, Ireland Merchants and Manufacturers do hereby declare the
nature of this invention to be as follows:-
The invention relates to improvements in or connected with thrashing machines.
In thrashing machines as ordinarily constructed, the cars and straw in the sheaf
are fed into the machine thus necessitating the employment of shaking and trussing
machinery.
Now the object of the present invention is to combine with the feed drum a
simple device by the aid of which the cars will be severed from the sheaves and
passed into the machine leaving the straw in sheaf upon the feeding platform
thereby dispensing with the shaking and trussing machinery hitherto employed.
For this purpose I fix upon one end of the feed drum or upon its shaft a circular
saw, or it might be a band saw, band knife, or other cutting device of suitable
diameter, against which the sheaves may be fed by hand, or by passing between a
pair of endless bands or by other suitable mechanisın.
The heads will be severed from the sheaf, and will drop into the machine whilst
the straw still in the sheaf can be removed by any suitable means.
By combining the saw or cutting device with the drum in the manner herein-
before described, a very simple and inexpensive machine is obtained, and a
considerable economy of power and space effected.

COMPLETE SPECIFICATION.
Improvements in or connected with Thrashing Machines.
1, WILLIAM MCKENZIE, a Director of the Firm of Thomas McKenzie and
Sons Limited, of 212 Great Brunswick Street, in the City and County of Dublin,
Ireland, Merchants and Manufacturers, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention relates to improvements in or connected with thrashing machines.
In thrashing machines as ordinarily constructed, the ears and straw in the sheaf
are fed into the machine, thus necessitating the employment of shaking and trussing
machinery.
Now the object of the present invention is to combine with the feed drum a
simple device, by the aid of which the cars will be severed from the sheaves and
passed into the machine leaving the straw in sheaf upon the feeding platform,
thereby dispensing with the shaking and trussing machinery hitherto employed.
For this purpose I fix upon ove end of the feed drum or upon its shaft a circular
saw, or it might be a baud saw, band knife, or other cutting device, against which

page_text: the sheaves may be fed by hand, or by passing between a pair of endless bands, or
by other suitable mechanism. The heads will In severed from the sheaf and will
drop into the machine whilst the straw still in the sheaf can be removed by any
suitable means.
By combining the saw or cutting device with the drum in the manner herein-
before described, a very simple and inexpensive machine is obtained, and n
considerable economy of power and space effected.
The better to explain my meaning reference is made to the accompanying
drawings in which :-
Fig. 1. is a section showing a portion of the usual arrangement of a thrashing
machine.
Fig. 2. is a section enlarged showing the cutting arrangement,
Fig. 3. is a cross section of the same.
Similar letters in each refer to similar parts.
In Fig. 1. A. is the axle of the beating cylinder B. shown dotted. C. is the
concave. D. is the shaking shoe. E. is the straw elevator, and F. is the feed
board. The grain falls as shown in dotted lines on to D. and the straw follows
the direction of the arrows adjacent.
In my arrangement instead of treating (as in such a machine) the whole shenf,
I use in conjunction with the drum or cylinder a saw as shown in Figs. 2 and 3, :
whereby the cars are severed and alone are treated allowing a great reduction to he
made in the size of the machine.
For clearness and simplicity, a common type of saw is illustrated, but obviously
a different type of teeth may be used or kuives may replace the teeth.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what |
claim is:-
1. In thrashing machines a cutting device for sovering the ears or heads from
the straw substantially as described.
2. A machine for thrashing constructed so as to dispense with the shaking or
trussing machinery hitherto employed, substantially as described.
3. An improved thrashing machine substantially as described and set forth in
the foregoing Specification.
