Improvements in Agricultural Implements, such as Trussing Knives,
Hay Knives, Scythes, and the like.
I, THOMAS ALLWOOD LINACRE, of Hackenthorpe, in the County of Derby, Scythe
Smith, do hereby declare the nature of my said invention to be as follows:-
Although my invention is applicable to various kinds of agricultural implements a
description of it as applied to a hay trussing knife will suffice. Such knives as
ordinarily made are constructed with blados mado partly of iron and partly of steel,
the cutting edge being formed of steel, and the back of the blade which is thickened
and formed with a rib or ribs terminating in a tang, being made of iron. The tang
is drawn out sufficiently far from the blade to allow of a handle being fitted thereto
In some cases the tang is formed for use with a side handle and sometimes for use
with a cross handle, but in either case the space betwoon the handle and the blade is
invariably made too short for the most effective method of working the knife. This
however, can be obtained by increasing the distance between the handle and the blade
which gives greater leverage and power in using the knife.
I effect this improvement, by employing a tubulous metallic handle to which I
secure the binde by means of a short screwed tang formed on the blade, the screwed
end of the tang being made to fit the internal threads in the tubnlar handle so that
when screwed up tight, the handle and the tang of the blade are of the same diameter
externally and flush with one another. To prevent these parts from becoming
unscrewed, I further secure them by means of a pin, rivet, or screw. The tubulous
handle thus employed, I either bend and form into a side handle, or into a cross
handle as may be required, thereby dispensing with the wooden handle usually
aupplied.
In some cases where a cross handle of wood is preferred, I form a metallic fork or
connecting bolt which I screw at the end and by means of which the wood handle
can be attached to the tubulous metallic handle of the knife and secured thereto
in a manner similar to that described for attaching the tang of the blade to the saine.
The above mode of construction is equally applicable to a truss or hay knife, where
the cutting edge of the blade, the back and the tang are all made out of one solid
piece of steel.
It will also be seen that the same mode of constructing tubulous metallic handles
and connecting the same to the blades is likewise applicable to hay spades, scythes,
and the like implements.

I, THOMAS ALLWOOD LINAORE, of Hackenthorpo, in the County of Derby, Soythe
Smith, do hereby declare the nature of my said invention and in what manner the same
is to be performed, to be particularly described and ascertained, in and by the following
statement :-
"
Although my invention is applicable to various kinds of agricultural implements a
description of it as applied to a hay trussing knife will suffice. Such knives as
ordinarily made are constructed with blades made partly of iron and partly of steel,
the cutting edge being formed of steel, and the back of the blade which is thickened
and formed with a rib or ribs terminating in a tang, being unade of iron. The tang
is drawn out sufficiently far from the blade to allow of a handle being fitted thereto.
In some cases the tang is formod for use with a side handle and sometinies for use
with a cross haudle, but in either case the space between the handle and the blade is
invariably made too short for the most effective method of working the knife. This
however, can be obtained by increasing the distance between the handle and the blade
which gives greater leverage and power in using the knife.
I effect this improvement by supplying metallic tabular handles in the following
manner.
My invention will be better understood on reference to the accompanying sheet of
drawings, in which,
Fig. 1. is a side elevation of a hay trussing knife fitted with one of my improved
metallic tubulous side handles.
Fig. 2. being an ond view, and
Fig. 3. a plan of the same.
Figs. 4, 5, & 6, are similar views of a hay trossing knife fitted with one of my
improved metallic tubulous handles or shanks in combination with a wooden cross
haudle.
Fig. 7. is a side elevation of a hay cutting spade fitted in a like manner with one of
my improved metallic tubulous handles.
Fig. 8. being an end view and
Fig. 9. a plan of the same.
The same letters refer to similar parts throughout the several views.
My improved tubulous metallic handle I secure, as shown in Figs. 1, 2, & 3, to the
blade, b, by means of a short screwed tang, c, formed on the blade and shown by
dotted lines, the screwed end of the tang being made to fit the internal threads in the
tubular bandle, a, so that when screwed up tight, the handle and the tang of the blade
are of the same diameter exterually and flush with one another.
To prevent these parts from becoming unscrewed, I further secure them by means
of a pin, rivet, or screw, d, or in some cases the two parts, a and b, may be welded or
brazed together either with or without the screwed joint at c, the tubulous handle
or shank, a, thus employed I oither bend or form into a side handle as shewn in
Figs. 1, 2, & 3, or into the shank of a cross handle as illustrated in Figs. 4, 5 & 6,
as may be required, thereby dispensing with the wooden handle or shank usually
employed. In some cases where a cross handle of wood, e, is preferred I form a
metallic fork or connecting bolt,, which I screw at the ends, g, n, and by means of
which the wood cross bandle may be secured. The fork bolt, f, I secure to the
metallic handle or shank, a, of the knife by means of a screwed joint, h, in a manner
similar to that described for attaching the tung, c, of the blade to the same.
The above mode of construction is equally applicable to a truss or hay knife, where

page_text: the cutting edge of the blade, the back and the taug are all made out of one solid
piece of steel.
It will also be seen that the same mode of constructing tubulous metallic handles-
and connecting the same to the blades is likewise applicable to hay spades, as shewn
in Figs. 7, 8, & 9, also to soythes, and the like implements.
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. In agricultural imploments such as trussing knives, hay knives, hay spades,
scythes and the like, the application of tubulous metallic shanks or handles in
combination with the particular mode of forming, shaping, bending, and securing
the same to the blade, in the manner and for the purposes substantially as herein
described and illustrated in Figs. 1, 2, 8, 7, 8, & 9, in the accompanying sheet of
drawings.
2. In agricultural implements such as trussing knives, hay knives, hay spades,
scythes and the like, the application of tubulous metallic shanks in combination with.
wooden cross bandles and the particular mode of forming, shaping, bending and
securing the same both to the shank and to the blade in the manner and for the
purposes substantially as herein described and illustrated in Figs. 4, 5, & 6, of the-
accompanying sheet of drawings.
3. Improvements in agricultural implements such as trussing knives, hay knives,
hay spades, scythes and the like, in the manner and for the purposes substantially as -
herein described and illustrated in the accompanying sheet of drawings.
