PROVISIONAL SPECIFICATION.
'An Improved Apparatus for Cutting the Bands of Sheaves and
Elevating the same to Thrashing Machines.
DAVID EBENEZER CARR, Felkington, Berwick-on-Tweed, England, Farmer, do
hereby declare the nature of this invention to be as follows:-
A labour-saving machine to be used in the operation of thrashing grain; consisting
of a wooden trough, open at both ends, 14 inches in depth; 16 inches in width;
and from 10 feet upwards in length. At each end of said trough, its upper surface
level with the bottom thereof, is a roller: round these rollers moves an endless
canvas which constitutes the elevating medium. One third of troughs length from
the delivery end of same, is a steel disc-22 inches diameter-revolving in the
centre of the trough, vertical to elevating canvas, and having its edge at a hight of
inches above said elevating canvas. This steel disc constitutes the cutting
medium.

COMPLETE SPECIFICATION.
An Improved Apparatus for Outting the Bands of Sheaves and
Elevating the same to Thrashing Machines.
DAVID EBENEZER CARR, Felkington, Berwick-on-Tweed, England, Farmer, 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:
This invention is a labour-saving apparatus for use in the operation of thrashing
grain out of the sheaf. Its utility consists in elevating sheaves to the feeding
board of the thrashing machine, and in cutting the bands of the sheaves while in
the act of being elevated. The invention consists of a trough made of wood, or
any other suitable material, of an indefinite length, or of a length suited to the
requirements of the place or position in which the machine is to be erected; this
trough is open at both ends: its depth is about 14 inches; its width about 16 inches.
At each end of said trough is placed a roller; the top surfaces of these rollers are.
running level with the bottom of said trough: around said rollers is made to
revolve a belt made of canvas, or any other material suited to the purpose; this
belt, passing under and over the bottom of aforesaid trough, constitutes the elevating
medium of the invention. About 4 feet from the discharge end of aforesaid trough,
and revolving in the centre thereof, and parallel with the sides thereof, is placed a
thin steel disc of about 22 inches in diameter. The lower edge of this disc runs at
a distance of about 3 inches above the elevating belt. This said disc rotates on a
spindle running in bearings resting on the sides of trough aforesaid, and constitutes
the cutting medium of the invention. On each end of disc-spindle, which project in
order to admit thereof, is placed a pully to one of these pullys is communicated
the motive power from the thrashing machine; from the other pully is driven a
belt communicating with, and giving motion to the driving roller of the elevating
belt. This invention can be applied to either fixed or travelling thrashing machines.
:
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same may be performed, I declare that what I
claim is:-
1. That the elevating principle of this machine, as contained in the trough, is
antival now

page_text: 2. That the cutting principle of this machine, as contained in the revolving steel
disc, is entirely new.
3. That the combination of the elevating and cutting principles of this machine,
is entirely new.,
