I, WILLIAM GOULDING, of the Borough of Leicester, in the County of
Leicester, Plough Maker, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF PLOUGHS," to be as follows:—
This Invention has for its object improvements in the construction of
ploughs. When ploughshares have been in use for some time, the point
becomes worn, and in order to make the plough work satisfactorily it is then
necessary either to fit a new share to the plough, or else to alter the position
of the share so that its point may penetrate to the same depth as at first or
before it became worn. This has heretofore been done by mounting the share
on what is known as a lever neck, which allows the point of the share to be
moved up and down in a vertical plane, and to be set to any degree of
"keenness" desired; but when lever necks are employed, the share moves
independently of the mould board, consequently there can only be one position
of the share in which its surface or face is in such a position as to form a
continuation of the surface of the mould board without break in the curve, and
when there is a break in this curve, the ploughing becomes more or less
imperfect.
Now, according to my Invention I arrange the parts of the plough so
that when it is required to set down the point of the share, the share and the
mould board may move together, but independently of the sole plate or bottom

page_text: of the slipe. For this purpose I connect together the share and the body or
frame of the plough, as heretofore in ploughs, in which lever necks are not
employed, and in place of fixing the slipe to the frame, as heretofore, I attach
it thereto by a joint at its fore end, so that the sole plate or bottom of the slipe
may be raised and lowered independently of the body or frame. The parts are
set and fixed when in the desired positions by means of a screw and nut, or it
may be by other convenient mechanical means. In order to connect the
wheels which support the fore part of the plough to the beam, I adopt the
following means:-I form a slot through the beam from its upper to its under
surface, at the point where the wheels are to be attached; and in the under
side of the beam, at the slotted part, I form shallow notches, in which lay two
bars; and these bars have attached to them at their extremeties the standards
to which the wheels are secured, as is herein-after described. The bars are
held in their position in the notches in the beam by means of eyes, through
which they pass; and the eyes are furnished with screw stems, which pass up
through the slot in the beam and through holes in covering plates laid on the
top of the beam over the slot. Nuts are screwed on to the ends of the stems,
and the eyes are thus drawn up, so as to join the bars against the under side
of the beam. Each of the bars at its end is bent round at right angles, and is
forked so that the standard on which the wheel is mounted may lay in the
fork, and it is there secured by passing through an eye having a screw stem
passing through the bar, and receiving beyond it a screw nut; thus when the
nut is screwed up on the stem, the standard becomes firmly jammed in the
fork at the end of the bar; by this arrangement the wheels may be brought
opposite to each other, and the adjustment of the distance between the wheels
and also of their distance from the beam is easily effected.
