PROVISIONAL SPECIFICATION.
Improvements in and relating to Mowing and Reaping Machines.
I, EDWARD GEORGE PAINE, of Manor Farm, Compton Abbas, in the County
of Dorset, Farmer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved method of mounting the knives on the
knife bar, and it consists in forming at the back end of each knife on one side
thereof a tongue adapted to lie over, or under, the side of the next adjacent knife so
that one bolt or rivet fixes the sides of the two adjacent knives to the knife bar. If
the tongues on the knives are adapted to lie over the adjacent knives the knife bar
may be made flat, but if they are adapted to lie under the adjacent knives then
the knife bar must be grooved to take the said tongues. The backs of the knives
are preferably turned down to form flanges adapted to bear against the back of the
knife bar.
By this construction the knives mutually support each other, giving great
strength and stiffness, while the back flanges preserve the knife bar from being
pitted by the friction of the knife guides.
Dated this 21st day of April 1894.

Improvements in and relating to Mowing and Reaping Machines.
I, EDWARD GEORGE PAINE, of Manor Farm, Compton Abbas, in the County
of Dorset, 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 :-
My invention relates to an inproved method of mounting the knives on the
knife bar, and it consists in forming at the back end of each knife on one side
thereof a tongue adapted to lie over, or under, the side of the next adjacent knife
so that one bolt or rivet fixes the sides of the two adjacent knives to the knife bar.
If the tongues on the knives are adapted to lie over the adjacent knives the knife
bar may be made flat, but if they are adapted to lie under the adjaceut knives then
the knife bar must be grooved to take the said tongues. The backs of the knives
are preferably turned down to form flanges adapted to bear against the back of
the knife bar.
By this construction the knives mutually support each other, giving great
strength and stiffness, while the back flanges preserve the knife bar from being
pitted by the friction of the knife guides.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing in which :-
Figure 1 is a broken view in plan of one form my invention may assume.

page_text: and
Figure 2 is a view in section on line a, z, Figure 1.
Figure 3 is a view in section on line y, y, Figure 1.
Figure 4 is a broken view in plan of another form my invention may assume,
Figures 5 and 6 are views in section on lines a, a, and y, y, Figure 4
respectively.
Throughout the views similar parts are marked with like letters of reference.
On to the back end of each knife A on one side thereof is a tongue a adapted
to lie either under the opposite side a' of the adjacent knife A as shown by
Figures 1, 2 and 3, or over the opposite side a' of the adjacent knife A as shown
by Figures 4, 5 and 6, so that one bolt or rivet B fixes the sides of two adjacent
knives to the knife bar c.
If the knives a are adapted to lie under the adjacent knives the knife bar C
must be formed with a groove c to take the said tongues as shown by Figures 1, 2
and 3, but if the tongues are adapted to lie over the adjacent knives the knife
bar C may be flat. as shown by Figures 4, 5 and 6.
The back ends of the knives are preferably turned down to form a flange a
adapted to bear against the back of the knife bar C, but this is not obligatory.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereiubefore described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
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 I
claim is:-
1. The improved method of mounting the knives of mowing and reaping
machines, substantially as set forth.
2. In a mowing or reaping machine, the combination of knives such as A having
tongues such as a on one side of their back ends adapted to lie under the sides of
the adjacent knives, and of a grooved knife bar adapted to receive the said kuives
to which they are fixed by bolts or rivets such as B, as set forth.
3. In a mowing or reaping machine, the combination of knives such as A having
tongues such as a on one side of their back ends adapted to lie over the sides of
the adjacent knives and of a knife bar such as c to which the said knives are fixed
by bolts or rivets such as B, as and for the purpose set forth.
4. In knives for mowing or reaping machines, forming a tongue on one side of
the back end of the knife and a flange on the back edge thereof, as and for the
purpose set forth.
