PROVISIONAL SPECIFICATION.
Improvements in the Shares or Points of Horse-hoes and other
similar Implements.
I, CRISPUS COTTIS of The Archimedean Iron Works, Epping, in the County
of Essex, Agricultural Implement Maker, do hereby declare the nature of this
invention to be as follows:-
:-
My invention relates to the detachable connection of hoe points or shares to their
tines or stems in horse hoes and other agricultural machines (such as scuffle drags,
grubbers, and scarifiers) described in a previous application for Letters Patent
dated April 17th 1891, No. 6666. The present improvements relate to the mode
of forming the tapering socket on the hoe point or share which fits on the tine
or stem.
In making a cast iron hoe blade, the socket is make of a steel band bent to the
proper half-round tapering form the ends of the band at either side of the socket
being embedded in the metal of the hoe by placing the band in the mould and
casting the metal around the ends of the band. Such a steel band being thinner
than could be made in cast-iron would form less obstruction to, and work easier in,
the ground.
In the case of a steel hoe, the hoe would be perforated with two slots to receive
the ends of a staple-shaped steel band, the ends forming tenons which are secured
in the slots in the hoe by rivetting or clenching at the underside.
For side cutting and furrow hoes in which the share whether flat or curved
extends wholly from one side only of the socket, the share is made by cutting out
from a plate of mild steel, the socket being formed in one therewith by bending an
extension (left for the purpose at one edge of the hoe) over a mandrel of proper
shape to form the tapering half-round socket required, and welding the free edge of
the bent over portion to the hoe blade.

COMPLETE SPECIFICATION.
Improvements in the Shares or Points of Horse-hoes and other
similar Implements.
I, CRISPUS COTTIS of The Archimedean Iron Works, Epping, in the County
of Essex, Agricultural Implement Maker, 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 the detachable connection of hoe points or shares to their
tines or stems in horse-hoes and other agricultural machines (such as scuffle drags,
grubbers, and scarifiers) described in a previous application for Letters Patent
dated April 17th 1891, No. 6666. The present improvements relate to the mode of
forming the tapering socket on the hoe point or share which fits on the tine
or stem.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a cross-section of a cast iron hoe point with the steel band per-
manently secured by casting the metal around the ends of the band,

page_text: Figure 2 is a similar view of a cast iron hoe point with the steel band removably
attached by its ends being received in a recess cast in the hoe.
Figure 3 is a rear view and Figure 4 a longitudinal section shewing the steel
band rivetted into a wrought steel hoe point which is shewn separately in plan in
Figure 5.
'
Figures 6, 7, 8, are a front view, side view, and plan, of a side cutting or furrow
hoe.
The same letters of reference denote like parts in all the figures.
In making a cast iron hoe blade, the tapering socket which fits on the foot of the
tine or stem, is made of a steel band a bent to the proper half-round tapering form
the ends of the band at either side of the socket being outwardly bent as at a' and
embedded in the metal of the hoe either by placing the band in the mould and
casting the metal around the ends of the band, as in Figure 1 or by casting the hoe
with a recessed aperture 6 as in Figure 2 in which the band is inserted and is
retained in position therein by the foot of the tine when inserted in the socket.
Such a steel band being thinner than could be made in cast iron would form less
obstruction to, and work easier in, the ground.
In the case of a wrought steel hoe, as in Figures 3, 4, 5, the hoe would be
perforated with two slots cc to receive the ends of a staple-shaped steel band a the
ends a of which form tenons which are secured in the slots c in the hoe by rivetting
or clenching at the underside, as in Figures 3 and 4.
For side cutting and furrow hoes in which the share, whether flat or curved,
extends wholly from one side only of the socket, as in Figures 6, 7, and 8, the
share is made by cutting out from a plate of mild steel the socket a being formed
in one therewith by bending an extension (left for the purpose at one edge of the
hoe) over a mandrel of proper shape to form the tapering half-round socket required
and welding the free edge of the bent-over portion to the hoe blade.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The combination, with a cast iron hoe share, of a steel band socket having its
ends bent outwards and embedded or fixed in the casting, substantially in the
manner herein specified.
2. The combination, with a wrought steel hoe share, of a steel band socket having
its ends rivetted in slots in the hoe blade, as described.
3. A side cutting or furrow hoe blade having the tapering socket formed in one
therewith by bending over and welding an extension of the blade, as specified.
