PROVISIONAL SPECIFICATION.
Improvements in and relating to Ploughs.
I, JAMES BACKHOUSE, of Whitchurch, Hants, Engineer and Machinist, do
hereby declare the nature of this invention to be as follows:-
In the Specification of my Patent No. 4671 of 1892 I have described certain
means for effecting firstly the regulation of the depth of furrows to be cut, and,
secondly, for regulating the width of the furrows. My present invention relates to
improved means which I adopt for regulating the depth of furrows in substitution
for the arrangement described in the Specification of my Patent above referred to.
That is to say-In the plough head or "skife" is formed a rectangularly shaped
opening to allow of there being introduced thereinto an eccentric, and eccentric
block, the latter having a certain amount of lateral play, within the opening above
referred to, equal to the throw of the eccentric. The eccentric pin passes through
the plough framing and has adapted to it a short lever arm having attached to the
outer end thereof a connecting rod fulcrumed to a hand lever under the control of
the ploughman at the yokes. To regulate the height, it is simply necessary to
pull or push (as the case may be) whether raising or lowering, is required to be
effected, the hand lever, whereupon the plough head or
" skife and with it the
share will be bodily raised, or lowered, as the case may be. Provision is made by
employment, in connection with the working lever aforesaid, of a pin and rack or
other suitable means for retaining the plough head and share at the desired
ploughing height.
The operations above described for altering depth of furrow, are carried out
with facility by the ploughman at the yokes or handles, as the work proceeds,
according to the varying requirements.
Dated this 31st day of May 1894.

Improvements in and relating to Ploughs.
I, JAMES BACKHOUSE, of Whitchurch, Hants, 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:-
In the Specification of my Patent No. 4671 of 1892, I have described certain
means for effecting, firstly; the regulation of the depth of furrows to be cut; and,
secondly; for regulating the width of the furrows. My present invention relates
to improved means which I adopt for regulating the depth of furrows in substitution
for the arrangement described in the Specification of my Patent above referred to.
And in order that my invention may be the better understood, I have appended
the accompanying sheet of drawings illustrative thereof, in which Figure 1
represents a side elevational view of a plough in accordance with my present
improvements; Figure 2, a plan view; and, Figure 3, being a detail view to an
D17

page_text: enlarged scale of the skife or body part of a plough in accordance with my
improvements aforesaid.
In the drawings the same letters of reference are employed to denote like parts
throughout the several figures.
In carrying out my invention I form in the plough head or skife a a rectangular
shaped opening to allow of there being introduced thereinto the means for
effecting the adjustment of the plough body. Said means consisting preferably of
an eccentric c and eccentric block d, the latter having a certain amount of lateral
play. The eccentric pin e passes through the plough framing a, and has adapted
to it a short lever arm, having attached to the outer end thereof a connecting
rud fulcrumed to a hand lever h under the control of the ploughman at the
yokes.
The plough head or skife a is carried, behind the eccentric e, on a pin or bolt i
having long bearings, to impart and ensure steadiness to the implement, and to
allow the plough head or skife a to work easily up and down as is required. The
usual turn furrow and coulter are also fixed to the plough head or skife a so as to
retain their relative positions at all depths. To regulate the height or depth; it is
simply necessary to pull, or push (as the case may be whether raising or lowering,
is required to be effected) the hand lever h, whereupon the plough head or skife a
and with it the share and the other parts of the plough herein identified as being
secured to the skife, will be raised or lowered as the case may be. Provision is
made by employment, in connection with the hand lever aforesaid, of a pin and
rack or other suitable means for retaining the plough head and parts attached
thereto at the desired ploughing height.
Although, as above described and shown in the accompanying drawings, I prefer
to use, for the adjustment of the plough head or skife, an eccentric and eccentric
block, fitted to the skife or body of the plough, with a lever attached, connected to
another lever which is fulcrumed to a bracket placed in the plough handles; still,
said adjustment can be effected, as will be apparent, in other ways, such for
instance as by the employment of a simple lever, to take the place of the eccentric,
or by the adoption of a worm or rack and pinion.
The operations above described, for altering depth of furrows, are carried out
with facility, by the ploughman at the yokes or handles, as the work proceeds,
according to the varying requirements.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In ploughs the method of and means for raising and lowering the body or skife
of the plough which is carried on a hinged joint substantially as and for the
purposes herein described and shown in the accompanying sheet of drawings.
