PROVISIONAL SPECIFICATION.
Improvements in and Applicable to Horse Hoes, Land Scufflers,
and Harrows.
I EDMUND EVANS, of Walton, near Kington, in the county of Radnor, Machinist, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and applicable to horse hoes, land scufflers
and harrows, and the invention consists in the application to the said implements of
open gear wheels and an endless chain for driving a revolving harrow placed thereon.
In carrying out my invention as applied to a horse hoe for example, I fix an open
gear or sprocket wheel on the front wheel of the implement; from a suitable part of
the implement I suspend a small open gear or sprocket wheel round which and round
the front sprocket wheel I pass a chain; over a second sprocket wheel on the same
axis as the said small wheel I pass a chain extending to and around a sprocket wheel
on the revolving harrow.
By this construction, when the implement is moved along, the front wheel thereof
by means of the said chains and open gear, will communicate the required rotary
motion to the harrow.

page_text: I, EDMUND EVANS, of Walton, near Kington, in the county of Radnor, Machinist
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 relates to improvements in and applicable to horse hoes, land scufflers,
and ploughs, and the invention consists in the application to the said implements of
open gear wheels and an endless chain for driving a revolving harrow placed thereon.
In carrying out my invention as applied to a horse hoe for example, I fix an open
gear or sprocket wheel on the front wheel of the implement; from a suitable part of
the implement I suspend a small open gear or sprocket wheel round which and round
the front sprocket wheel I pass a chain; over a second sprocket wheel on the same
axis as the said small wheel I pass a chain extending to and round a sprocket wheel
on the revolving harrow, or I can employ a single chain driving the harrow direct
from the front wheel.
In order to enable my invention to be fully understood I will describe how the same
can be carried into effect by reference to the accompanying drawings in which figure 1
represents by way of example a side elevation of a horse hoe with my improvements
applied thereto, two chains being shewn for operating the harrow; figure 2 is a
similar view of a horse hoc illustrating my improved means for driving a harrow by
means of a single chain. Similar letters in both the figures represent similar parts.
Referring to figure 1 a, represents the frame of the horse hoe, b, b, the tines, e, the
front or travelling wheel, and d, one of the handles of the implement, all of which
parts are of ordinary construction.
e,
is the open gear or sprocket wheel which I fix on the front wheel of the implement ;
f, is the small open gear or sprocket wheel which 1 suspend from the frame a, of the
implement by means of a hanging bracket g; h, is the chain which passes round
the open gear or sprocket wheels e, and f; i, is the second sprocket wheel mounted
on the same axis j, as the wheelf; k, is the revolving harrow mounted in a pair of
banging brackets (one of which is shewn at 7) fixed to the frame a, of the implement ;
m, is the sprocket wheel which I fix to the boss of the revolving harrow k, and n, is
the chain which passes round the sprocket wheels i, and m.
By this construction when the implement is moved along, the front wheel c, thereof
by means of the chains h, and n, and open gear wheels e, f, i, and m, will communicate
the required rotary motion to the harrow k

page_text: When driving the harrow k, by means of a single chain, as shewn in figure 2, I
employ a similar arrangement of sprocket wheels to that illustrated in figure 1 except
that the wheels f, and i, are not required and I find it advantageous, where the
implement has a comparatively large front wheel c, as shewn in the drawing, to mount
two rollers
0, and p, on the bracket 9, to guide the chain h, to the sprocket wheel m.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The use in combination with horse hoes, land scufflers, and ploughs of open gear
wheels and an endless chain or chains for driving a revolving harrow attached thereto.
2. The improved horse-hoes hereinbefore described and illustrated in the accom-
panying drawings.
