PROVISIONAL SPECIFICATION.
Improvements in Single and Double Furrow Turn Wrest Ploughs.
I, JOHN HUXTABLE, of Plough Works, Filleigh near South Molton, in the County
of Devon Machinist and Agricultural Implement Maker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in such turn wrest ploughs as are made
with the handles to rotate, for the purpose, among others, of matching either the
right or left sets of ploughing tools. For this purpose I employ a bar of suitable
proportions made firm to the handles or their connections. The said har is carried
forward by the side of the beam or beams, and is supported and free to turn in
suitable bearings fixed on the framework or beams of the plough. At or near the
end of this bar I fix a mitre or other suitable shaped cog wheel, and a corresponding
one to gear into it I fix on a shaft connected to the furrow and land wheels or their
attachments, so that by rotating the handles with the bar and mitre wheel, motion is
imparted to the mitre wheels fixed on the shaft carrying the land and furrow wheels
and puts them in proper position to match either sets of ploughing tools intended for
work. These mitre or other shaped cog wheels have stops fixed on them in suitable
positions to determine their distance of travel and to check their progress when the
stems of land and furrow wheels assume a vertical position.
My invention also relates to fixing points to any kind of plough shares so as to
give them more or less pitch as required. In order to accomplish this I make the
socket in which the point fits, of a serrated shape longitudinally or otherwise, and
corresponding serrations in the point that fits therein, so that by changing the point
from one serration to another it shall give to the said point more or less pitch or
inclination to the ground.

COMPLETE SPECIFICATION.
Improvements in Single and Double Furrow Turn Wrest Ploughs.
I, JOHN HUXTABLE of Plough Works, Filleigh, near South Molton, in the
County of Devon, Machinist and 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:-
This invention relates to improvements in such turn wrest ploughs as are made
with the handles to rotate, for the purpose, among others, of matching either the
right or left sets of ploughing tools when turned upside down at the headlands,
and I will describe my invention by reference to the accompanying drawings.
Figure 1 is a plan of the framework of a plough or so much of same as will
be necessary to describe my invention showing my improvements applied thereto.
Figure 2 is an inverted plan of the front portion of the plough drawn to a larger
scale than the previous figure, and Figure is a vertical section on the line ay of
Figure 2 looking from the front of the plough. Figure 4 is a vertical section on
the line y of Figure 2 and Figure 5 shows the ploughing tools in working
position.
Similar letters of reference refer to like parts in all the figures..
The handles of the plough shown at Figure 1 are fitted thereto in a similar manner

page_text: to that described in the specification of my patent dated 8 November 1877 No. 4176.
To the disc marked U in the specification of the patent before referred to I fix a
bar A of suitable proportions made firm to the handles B or their connections. The
said bar A is carried forward by the side of the beam or beams C and is supported
and free to turn in suitable bearings fixed on or formed with the framework or
beams of the plough. At or near the end of this bar A I fix a mitre or other
suitable shaped cog wheel D, and a corresponding one D¹ to gear into it I fix on a
shaft E, connected to the furrow and land wheels or their attachments, so that by
rotating the handles B with the bar A and mitre wheel D fixed thereto, motion is
imparted to the mitre wheel D¹ fixed on the shaft E carrying the land and furrow
wheels carried by the spindles G Figure 3 thereby putting them in proper position
to match either set of ploughing tools intended for work such as is indicated and
marked WXYZ Figure 5. These mitre or other shaped cog wheels DD' have
stops H H¹ fixed on or formed with them in suitable positions to determine their
distance of travel and to check their progress when the stems II' of land and furrow
wheels assume a vertical position.
These stops HH' are distinctly shown at Figures 2 and 4. The stop H¹ is
provided with adjustable studs H'H' which come against the face of the stop H and
are of such a size as to allow the wheels D D¹ to give a half turn and thereby to
reverse the position of the land and furrow wheels. The stops HH' effectually
prevent any backward strain in work which would otherwise be taken by the bar or
the cogs.
The stems I, I of the land and furrow wheels are made adjustable on the two
projecting ends of the shaft E the latter being slotted as shewn to ensure the stem I
being in the centre thereof; these stems 11 may be arranged in accordance with
the width of the furrow required, and to further this object the stem I¹ is made to
stand inclined to the bar E so that when reversed into the position shown by dotted
lines at Figure 3 it is rendered suitable for a wide furrow and obviates the bar E
being of such great length as otherwise would be necessary. In some cases' two
land wheels may be employed as described in my Specification No. 4176" and the
mechanism herein described may be employed for reversing the furrow-wheel for
example. In such cases, where only one of the wheels is to be reversed the bar E
may be cut off at one end.
My invention also relates to fixing points to any kind of plough or other shares so
as to give them more or less pitch as required. In order to accomplish this I make
the socket in which the point fits of a serrated shape longitudinally and corresponding
serrations in the point that fits therein so that by changing the point from one
serration to another it shall give to the said point, more or less pitch or inclination
to the ground.
This part of my invention is so clearly described that further reference to it'by
drawing is not necessary.
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 turn wrest ploughs the combination and arrangement of parts for the
reversing of the land and furrow wheels either together or separately by the
employment of reversal gear wheels D D', or other suitable shape wheels may be
employed which will impart motion at right angles by reversing the handles for the
purposes hereinbefore described or any mere modification thereof..
2. In turn wrest ploughs the application to the reversal: gear of stop
devices H, H¹, H³, the latter being adjustable by screws or otherwise. for the
purpose of counteracting the wear through backward pressure or any mere
modification thereof.
3. In turn wrest ploughs the bar E made with a slotted part as shown to ensure

page_text: the stem I being in the centre thereof together with the adjustable stem I' standing
in an oblique position for the purpose of taking a very wide furrow when reversed
on bar E as set forth.
4. In turn wrest ploughs the adjustable points on the shares formed with serrations
on one part corresponding with serrations on the other part substantially as set
forth.
