We, WILLIAM HENRY SLEEP and ROBERT HENRY SLEEP, both of the Excelsior
Plough Works, Plymouth, in the County of Devon, Engineers, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to ploughs of the kind wherein the shin or coulter extends
upwards from the back of the share and practically forms a continuation of the
same.
According to our invention we construct the parts mentioned in the novel
manner hereinafter described whereby we economize metal and thereby avoid
needless expense to the farmer for the renewal of parts, and also afford more room
underneath and reduce friction which enable the plough to enter hard and stiff
land and as the share has no tail rub or bearing that makes it ride out of the
ground the draught is lightened.
In carrying out our invention we divide our share and shin into four parts, viz.,
the point of the share, the wing and a shin in two parts. The point of the share
is fixed or put on the nose of the frame and fastened with a pin, the wing is bolted
on the frame behind the point with a bolt that goes through the wing and frame
or body of the plough. On the underside the wing has a lug or bead that runs
along by the side of the hole and comes to bear against the frame or body of the
plough and when the bolt is tightened with the nut it is quite firm and cannot
shift, ample room is provided for the nut under the wing so that it shall not come
into contact with the soil or ground. The frame or body is so constructed that it
will give the necessary room for such a bolt and nut.
The shin is in two parts, the front part that joins the point of share. with its
front end, and the front side of shin that joins or joints against the wing of the
share. The latter part is that which takes the greater part of wear and has
to be renewed often, when the upper part is but little worn. The front part has
two lugs or clips one of which is slipped under the land side of the wing, when
the bolt and nut of wing is loosened. The other lug or clip is slipped under the
front part of the top part of the shin when the bolt of shin is also loosened. When
the two lugs or clips are under the wing and shin the bolt of each should be screwed
tight, the whole share and shin being then fixed for work.

page_text: the nature of this invention and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement : -
Our invention relates to ploughs of the kind wherein the shin or coulter extends
upwards from the back of the share and practically forms a continuation of the
same.
According to our invention we construct the parts mentioned in the novel
manner hereinafter described whereby we economize metal and thereby avoid
needless expense to the farmer for the renewal of parts, and also afford more room
underneath so that the tail of the share will not bear or rub upon the ground
thereby reducing friction and lightening the draught and enabling the plough to
enter hard and stiff land without the liability of riding out of the ground.
In carrying out our invention we divide our share and shin into four parts, viz.,
the point of the share, the wing and a shin in two parts. The point of the share
is fixed or put on the nose of the frame and fastened with a pin, the wing is bolted
on the frame behind the point with a bolt that goes through the wing and frame
or body, of the plough. On the underside the wing has a lug or bead that bears
against the frame or body of the plough so that when the bolt is tightened..the
wing is quite firm and cannot shift. The frame or body is so constructed that
ample room is provided for the nut under the frame so that it shall not come into
contact with the soil or ground..
One part of the shin, viz., the front or lower part, joints against the point and
wing of the share, and is the part which is subject to the greatest wear and has
to be frequently renewed, whilst the upper part is but little worn. The lower part
has two lugs one of which is inserted under the wing, when the bolt and nut, of
wing is loosened, whilst the other is inserted under the lower end of the upper part
of the. shin. When the two lugs are under the wing and upper part of the shin
each bolt of the latter parts should be screwed tight; the whole share and shin are
then fixed for work.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figures 1, 2 and 3 are respectively a side elevation, a plan and an end elevation
of a plough frame arranged in accordance with our invention;
Figure 4 is a side elevation shewing the plough frame having applied to it our
improved share and shin.

Figures 5, 6 and 7 are sections on the lines 5-5, 6-6 and 7-7 respectively of
Figure 4:
Figure 8 is a view of the lower part of the shin detached; and, .
Figure 9 is a plan view of the wing of the share.
g
a is the plough frame which is cut away at b behind the nose c, as clearly shewn
in Figure 1, in order to afford the clearance behind the share so that the latter will
not bear or rub at its tail end upon the ground; the said frame is also hollowed out
on the land side so as to prevent unnecessary friction, as shewn at d in Figure 2,
and provided with a fin e on the furrow side to carry the wing of the share. f is
the point of the share, is the share wing and h, i are the upper and lower parts of
the shin respectively, the upper part h being attached to the surface j of the frame
by the bolt whilst the part i which is provided with lugs 1, 1, as clearly shewn
in Figure 8, has the said lugs arranged beneath the upper part h of the shin and
the edge of the wing g, as indicated by the dotted lines in Figure 4 and also in
Figure 6 with reference to the lug 7. Owing to the use of these lugs and to the way
in which the ends of the part i of the shin are formed and arranged between the
parth and the point f no bolt or other fixing is required for retaining the said
shin part in position.
m is the bolt which fixes the wing g of the share to the fin e of the frame and n
is the rib or bead formed upon the underside of the said wing and which makes
contact with, the edge of the fin e of the frame to hold the said wing against
movement.

page_text: With the arrangement of share and shin hereinbefore described it will be obvious
that any one part may be renewed without it being necessary to renew any other
part.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is:-
1. A plough, the share and shin of which are made in several pieces, sub-
stantially in the manner herein before described, so that either part can be renewed
without the necessity for renewing any other part.
2. In a plough, the share and shin of which are divided substantially as herein-
before described, a frame hollowed out behind the share so as to afford clearance,
for the purpose specified.
3. The improvements in the manufacture of ploughs hereinbefore described and
illustrated in the accompanying drawings.
