PROVISIONAL SPECIFICATION.
Improvements in Turn-wrest Ploughs.
I, WILLIAM HENRY SLEEP, of Excelsior Engineering Works, Plymouth, in the
County of Devon, Agricultural Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to turn-wrest or one way ploughs.
In carrying out my invention I combine with a suitable frame a pair of breasts
adapted to swivel or pivot relatively with the frame in such a manner that either
breast can be used according as to whether a right or left handed furrow slice is
to be turned and that when one breast is turning the furrow slice the other breast
will be in a position where it will not impede the proper working of the plough.
The share or point which is used is one which will work either for right or left
handed ploughing; and between the share and the breast I arrange what, for
convenience of description, I will term a guide plate; this guide plate is attached
to the front of the breasts in such a manner that when the breasts are moved the
guide plate takes up a position which practically makes it form a continuation of
the surface of the breast which is in work.
The coulter is adapted to be turned by means of a lever or tiller so that its
position may be caused to coincide with the position of the breast in work.
The front wheels are carried upon an axle which pivots relatively with the
beam whereby the position of the axle may be varied to bring the wheels into
the proper position to work, so that each wheel may serve as a land wheel when
working in one direction and as a furrow wheel when working in
the opposite direction. A suitable gravity catch is provided in con-
nection with this for locking the axle in position the said gravity catch being
operated by means of a suitable rod, chain or the like.
The frame of the plough is provided with a renewable shoe or slade and is used
in combination with a beam and handles of any desirable construction.

Improvements in Turn-wrest Ploughs.
f, WILLIAM HENRY SLEEP, of Excelsior Engineering Works, Plymouth, in the
County of Devon, Agricultural Engineer, 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 turn-wrest or one way ploughs.

page_text: In carrying out my invention I combine with a suitable frame a pair of breasts
adapted to swivel or pivot relatively with the frame in such a manner that either
breast can be used according as to whether a right or left handed furrow slice is
to be turned, and that when one breast is turning the furrow slice the other breast
will be in a position where it will not impede the proper working of the plough.
The share or point which is used is one which will work either for right or left
handed ploughing; and between the share and the breast I arrange what, for
convenience of description, I will term a. guide plate; this guide plate is attached
to the front of the breasts in such a manner that when the breasts are moved the
guide plate takes up a position which practically makes it form a continuation of
the surface of the breast which is in work.
The coulter is adapted to be turned by means of a lever or tiller so that its
position may be caused to coincide with the position of the breast in work.
The front wheels are carried upon an axle which pivots relatively with the
beam whereby the position of the axle may be varied to bring the wheels into
the proper position to work, so that each wheel may serve as a land wheel when
working in one direction and as a furrow wheel when working in
the opposite direction. A suitable gravity catch is provided in con-
nection with this for locking the axle in position, the said gravity catch being
operated by means of a suitable rod, chain or the like.
The frame of the plough is provided with a renewable shoe or slade and is used
in combination with a beam and handles of any desirable construction.
To enable my-invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:-
:-
Figure 1 is a side elevation of my improved plough; and
Figure 2 is a plan view of the same:
Figure 33 is a section on the line 3-3 Figure 1:
Figure 4 is a horizontal section on the line 4-4; Figure 1.
Figure 5 is a section on the line 5-5 Figure 1, but drawn to a larger scale
than the said Figure 4:
Figure 6 is a side elevation illustrating a slight modification.
a is the beam of the plough, b, b are the halls or handles and c is a bracket or
casting which, in conjunction with the nose or neck d of the plough, constitutes
the frame of the body. e is the coulter, e¹ the share and f, f are the wheels which
are of the same diameter each of which is adapted to work either as a land wheel
or a furrow wheel according to the direction in which the plough is working.
g is the part which, in the Provisional Specification, I term the guide plate.
This guide plate is in the form of a casting of approximately triangular shape in
plan view, as clearly shewn in Figure 4, and is mounted on the vertical pivot h
so that it is capable of being moved laterally to the right or left in order to cause
either side to be in practical alignment with the direction of movement of the
plough. i, are the breasts or mould boards which at their forward ends are fixed
to the rear edges of the guide plate g; so as to practically form a continuation of
the surfaces thereof, the said breasts or mould boards, at or near their rear extremi-
ties, being tied together by the bar j in which are formed a series of holes k, k,
into one or other of which the pointed end of a hand rod can be inserted to lock
the breasts for either right or left hand ploughing, that is to say, either in the
position shewn in full lines in Figure 4.or in the position shewn in the dotted
lines. With the arrangement herein before described it will be understiod that
when a furrow slice has been turned in one direction the ploughman, in order to
adapt the plough for turning a furrow slice in the opposite direction has to dis-
engage the rod from the bar j and to push over the breasts to the opposite posi-
tion and again insert the rod i to lock the breasts in this position.
m is the sole
plate or shoe upon the underside of the frame c.
It will be noticed by reference to Figure 4 that the shape e¹ is of similar shape
on both sides so as to permit it to work in conjunction with the breasts in either
position.

page_text: In order that the coulter e may be moved to one side or the other to correspond
with the position of the breasts, the said coulter is loosely mounted in a bracket n
on the beam a as clearly shewn in Figure 5 so as to be capable of being swung
laterally. The coulter is suspended upon a pin o extending across the, said
bracket and is provided with a series of holes o¹ so as to permit of adjusting the
depth at which it works. The lateral or swinging movement of the coulter is
effected by means of a lever or tiller p pivoted at one end upon a bracket n and
adapted at the other end to engage in notches q, q in a bar q¹ fixed to the handles.
The said lever has formed in it a slot r, as clearly shewn in Figure 5, through
which the stem of the coulter passes in such a manner that the movement of the
lever P from one notch to the other serves for rocking the coulter in the desired
manner.
To permit of the wheels f, f being adjusted to work either as land or furrow
wheels the axles is pivoted to the spill at t, the said spill being fixed in the
beam of the plough whereby it will be understood that the wheels can be placed
to work at different levels as required, for insance as shewn in Figure 3.
In order to lock the wheels f in either of their two positions I provide a gravity
catch u in the form of a collar sliding upon the spill and having a projection u¹
designed to engage upon one side or the other of a lug fixed to the axle and
oscillating therewith in a manner which will be readily understood by reference
to Figure 3. This gravity catch u is operated by the ploughman through the
medium of a rod w connected by a chain w¹, the said chain running against a
pin in the beam of the plough in such a manner that the longitudinal move-
ment of the rod w will cause a vertical movement of the said gravity catch to dis-
engage it from the lug v.
In the drawing the wheels f, f are represented as running upon short axles
which are adjustable relatively with the main axle s so as to permit of adjusting
the width of the same.
I sometimes slightly modify the construction herein before described by extend-
ing the handles b in a forward direction to form the neck carrying the share, as
clearly shewn in Figure 6, and in this case I connect the bean a to a bracket r
which is secured to the said handles. With this construction the frame c of the
plough body can be dispensed with, a spill y with a foot z upon it being used in
lieu of the sole platen herein before described. This sole plate is advantageously
made of triangular shape and the spill is provided with a tiller or lever y¹ so that
the said sole plate can be turned to the right or left to cut under the landside and
through all the weeds which are not cut by the share.
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
A turn-wrest plough having right and left handed breasts fixed to a pivoted
front portion and adapted to be moved together with the said front portion so as
to turn either a right or left handed furrow slice, the breast which is not turning
the furrow slice acting as a side plate, substantially as described.
2. In a turn-wrest plough, the combination with a pair of breasts or mould
boards fixed to a pivoted front portion and capable of moving therewith so as to
turn either a right or left handed furrow slice of a coulter mounted in the said
beam so that its position can be varied to correspond with the position of the
breasts and front portion, substantially as described.
3. In a turn-wrest plough the combination of a pair of breasts attached to a
front portion or plate and capable of moving so that either breast may be used
for turning the furrow slide whilst the other serves as a side plate and a pair of
wheels mounted on an axis capable of assuming an inclined position so that either
wheel may run in the furrow whilst the other runs upon the land, substantially
as described.
4. In a turn-wrest plough having right and left handed breasts fixed to a

page_text: pivoted front portion and adapted to be moved together with the said front por-
tion so as to turn either a right or left handed furrow slice a sole plate capable
of being moved upon a vertical axis, substantially as, and for the purpose,
described.
5. The improved turn-wrest plough constructed, arranged and operating sub-
stantially as herein before described and illustrated in the accompanying drawing.
