PROVISIONAL SPECIFICATION.
Improvements in and relating to Ploughs.
1. JAMES BACKHOUSE of Whitchurch, Hants, Engineer and Machinist do hereby
declare the nature of this invention to be as follows:-
My invention relates to improvements in ploughs, employed for agricultural
purposes, and consists, firstly of improved means for regulating the depth of the
furrows to be cut, and, secondly, for regulating the breadth of the furrows to be
cut, the same to be performed as the plough is being worked.
:
In carrying out my said invention under the first head thereof, I fix, by any
suitable means upon the plough beam, and upright vertical shaft carrying the
plough wheel, a bracket into which passes horizontally, a sliding block piece, said
sliding block piece has a diagonal slot cut therein into which works to and fro' a
pin and die projecting from the said upright or vertical shaft carrying the plough
wheels.
3
In working my improved apparatus to allow of the raising and lowering of the
plough, I provide a lever and, rack secured to the bottom of the ploughbody in any
suitable position within reach of the ploughman when at the handles; to this. lever
is adapted a connecting rod attached to the said sliding block piece by a hook or
any other suitable means.
By pulling or releasing the said lever the plough wheels are raised or lowered
the case may be and therefore regulating the depth of the furrows to be cut..
as
Under the second head of my said invention, namely, for the purpose of regulating
the width of the furrow, I fix a bracket (similar to the one above described) secured
to the axle of the plough wheels and passing. therethrough is a sliding block piece
working in the manner above described under the first head of my invention. .
I also attach a draught rod to any convenient part of the plough, preferably,
behind the ploughshare for the purpose of drawing the plough and I also fix thereto
a suitable bracket at the end of the plough beam to support the draught rod and
which allows the said draught rod to move freely from side to side and thus enabling
the ploughman to steer the plough, when at work..

COMPLETE SPECIFICATION.
Improvements in and relating to Ploughs.
1, JAMES BACKHOUSE, of Whitchurch, Hants, Engineer, and Machinist, 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 improvements in ploughs, employed for agricultural
purposes, and, consists, firstly, of improved means, for regulating the depth of the
furrows to be cut, and, secondly, for regulating the breadth of the furrows to be
cut, the same to be performed as the plough is being worked.
In carrying out my said invention under the first head thereof, I fix, by any
suitable means upon the plough beam and upright vertical shaft carrying the
plough wheel, a bracket, into which passes horizontally a sliding block piece, said
sliding block piece has a diagonal slot cut therein, into which work to and fro a
Do27

page_text: pin and die projecting from the said upright or vertical shaft carrying the plough
wheels.
In working my improved apparatus to allow of the raising and lowering of the
plough, I provide a lever and rack, secured to the bottom of the ploughbody in any
suitable position within reach of the ploughman when at the handles; to this lever
is adapted a connecting rod attached to the said sliding block piece by a hook or
any other suitable means.
By pulling or releasing the said lever, the plough wheels are raised or lowered
as the case may be and therefore regulating the depth of the furrows to be cut.
Under the second head of my said invention, namely for the purpose of regulating
the width of the furrow. I fix a bracket (similar to the one above described)
secured to the axle of the plough wheels, and passing therethrough is a sliding
block piece working in the manner above described under the first head of my
invention.
I also attach a draught rod to any convenient part of the plough, preferably
behind the ploughshare for the purpose of drawing the plough and I also fix thereto
a suitable bracket at the end of the plough beam to support the draught rod and
which allows the said draught rod to move freely from side to side and thus enabling
the ploughman to steer the plough when at work.
In the accompanying drawings,
Figure 1 a side elevation, and Figure 2 a plan of a plough provided with my
improvements.
•
Figures 3, 4, 5, 8 and 9 are details drawn at an enlarged scale of the arrangement
for altering or regulating the depth of the furrows.
Figures 6 and 7 are details showing the method of coupling the draw rod and
draw hook.
Figures. 10 and 11 are details of the arrangement for regulating the width of the
furrows..
Like letters of reference indicate corresponding parts throughout the figures.
The mechanism for allowing the ploughman to increase or decrease the depth of
the furrows, such as shown in Figures 1, 2, 3, 4, 5, 8 and 9, consists in fixing to the
axle A, m of the plough, a plate 7 (Figure 8) secured at the top to an upright
rode which passes through a bracket 6 mounted upon a box iron b, the latter being
fixed to the longitudinal beam of the plough. Within this bracket b and upon the
box iron slides a block or plate a furnished with a diagonal slot, in which the
ping secured to the upright rod c can be made to work. The sliding block or
plate a is furnished with a staple wherein engages the hooked end of the longitudinal
rod is the other end of this rod terminating with a ring whereby it is connected
to the lever furnished at its upper end with a handle, whilst its lower end is
secured to a strap bolted to the ploughframe. When the lever f' is moved in one
direction or the other, the sliding block is moved in the same direction, and raises
or lowers by means of the pin g, the rod c and with it the axle A, m thus increasing
or decreasing the depth of the furrow.
In Figures 1 and 2, 6 and 7, is shown the mode of connecting the draw bar and
hook to the plough frame and beam respectively. is an iron strap bolted to the
plough beam and through which passes the rod a having the shape shown in
Figure 7 and attached to the strap by the frame or the stirrup iron 7² secured
in position by the screw. The draught hook terminating the bar is thus
allowed a certain amount of play within the lower end of the rod a. The draw
bar p is allowed a certain amount of play, being formed with a ring at its rear end
connected to a similar ring formed at the front end of another bar por second part
of the draw bar proper. The rear end of this bar p is likewise formed with a ring
connected to that of a short link secured to the plough frame F.
As shown in Figure 8 the axle is formed of two parts A and m the end of the
part m being forked and connected by an adjustable screw frame to the other
part A or as shown in Figures 10 and 11, the part m may be terminated with a
sleeve passing over the upright end of the second and bent part A of the axle.

page_text: The latter figures also illustrate the arrangement for horizontally shifting to one
side the axle relatively to the plough, this arrangement being similar to that above
described whereby the said axle can be shifted vertically with the only difference
that it is at right angles to the former. is the block or plate sliding within the
bracket bolted to the axle A, m, and o, is the pin fixed to the draft bar, and
moving within the diagonal slot n formed in the sliding block or plate k, which is
actuated by a hand lever and rod (not shown in the drawing) in a similar manner
as above described.
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.
:-
First In ploughs, the mechanism for allowing the depth of the furrows to be
varied substantially as herein described and shown.
Second-In ploughs, the mechanism for enabling the width of the furrows to
be altered, substantially as herein described and shown.
Third In ploughs, the mode of coupling the draw rod and hook, substantially
as herein described and shown for the purpose of allowing free play thereto.
