COMPLETE SPECIFICATION.
Improvements connected with Ploughs.
I RICHARD HENRY WILLIAMS, of Liskeard Iron Works, Liskeard, Cornwall,
Engineer, do hereby declare the nature of my 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 certain improvements in Ploughs, and consists in fitting
a breast having two shares or cutting edges with a swivelling appliance carried by
the beam, so that the breast with the shares attached can be shifted under the beam
from one side to the other by the ploughman for right hand or for left hand
ploughing, the coulter of double convex shape in cross section being cranked and
movable independently of, or in conjunction with the share.
The invention will be understood by the annexed drawings.
Figure 1 is an elevation of a plough with the double edged share turned to the right
hand side and Figure 2 shows same plough with the double edged share on the left
hand side.
A is the breast. A', A', the shares. The breast is attached to straps B, B,
provided with square holed sockets C, C, through which passes the vertical rod D.
The lower end of this rod fits in a step piece E and the upper end in the eye of
a scroll iron F which also supports the worm wheel G and the fore end of the
longitudinal rod H, which end is provided with a worm I in gear with the worm
wheel G so that when the rod H is turned by its handle J the share A can be
shifted from one side to the other for right or for left hand ploughing as desired.
The scroll iron F is bolted to the beam K as is also the bracket L, by which the
coulter M is held in position but which coulter can be turned by the pull handle N to
suit the position of the breast A and shares A¹ A¹.
P, Pare the mould boards one on each side and Q, Q, are shoes on which the
plough runs and travels in the furrows.
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 :-
Fitting a plough frame or beam K with breast A having two shares A¹, A¹, and

page_text: shiftable under the beam to one side or to the other for right or for left hand
ploughing, substantially in the manner described with reference to the annexed
drawings.
