page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
SANDERS and WILLIAM WILLIAMS, of the Town of Bedford, in the County of
Bedford, Ironfounders, and SAMUEL LAWRENCE TAYLOR, of Old Warden, in the
said County of Bedford, Machine Maker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Third day of August, in the fourth year of her reign, did, for
Herself, Her heirs and successors, give and grant unto us, the said John
Sanders, William Williams, and Samuel Lawrence Taylor, Her especial licence,
full power, sole privilege, and authority, that we, the said John Sanders,
William Williams, and Samuel Lawrence Taylor, our exors, admors, and
assigns, or such others as we, the said John Sanders, William Williams, and
Samuel Lawrence Taylor, our exors, adiñors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the terni
of years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick Tweed, our Invention
of "IMPROVEMENTS IN PLOUGHS;" in which said Letters Patent is contained a
proviso, that we, the said John Sanders, William Williams, and Samuel Law-
rence Taylor, or some or one of us, shall cause a particular description of the
nature of our said Invention, and in what manner the same is to be performed,
to be inrolled in Her said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, with and by the same, reference being thereunto had, will more
fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, we, the said
John Sanders, William Williams, and Samuel Lawrence Taylor, do hereby
declare that the nature of our Invention, and the manner in which the same is
to be performed, are fully described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed, and
to the figures and letters marked thereon, that is to say:-
Our Invention relates to certain modes of applying and adjusting the coulter.
And in order to give the best information in our power, that our Invention may
be readily carried into effect, we will proceed to describe the Drawing.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a plough having a coulter applied according to our
Invention; and our modes of application have for their objects means of adjust-
ing, first, the distance of the coulter from the beam of the plough; and, secondly,
the inclination of the coulter. Figure 2 shows a side view, and Figure 3 a
plan, of the same parts for adjusting the coulter as are shown at Figure 1, but
on a larger scale, whereby the nature of the parts will be more readily traced.
a is the beam of the plough; is the coulter; and the coulter is applied to
the beam a by means of a frame, which moves on an axis or bolt c, passing
through the beam of the plough, and, by means of a set screw d. passing
through a fixed nut e, the angle of the coulter may be adjusted, for it will
be seen that there is a projection f from the plate f' against which the set
screw rests, and thus adjusts the position of the coulter, which is carried by
the frame plate f¹, as is shewn; and in order to adjust the distance of the
coulter from the beam a, the coulter is affixed in the following manner:-
g is a clamp, through which the stem of the coulter passes freely when not
fixed by the screw h, which passes through the back of the clamp y, and
rests against the projecting plate f, which forms part of and is a projection
at right angles to the face of the plate f', and there is a dovetail projec-
tion on which the plate i moves to or from the beam a of the plough,
the plate being suitably formed at the back to move on such dovetail
surface of the plate f", and the front of the plate i is concave to receive
the stem of the coulter; hence it will readily be understood that the plate i
can be slided to any desired position on the projecting plate f" on the frame
or plate f¹, and the coulter fixed thereto by the clamp and the screw h, and
the coulter will be caused to assume a more or less vertical position by means
of the screw d.
Figure 4 shews a plan, and Figure 5 a side view, of another arrangement
of the parts for accomplishing similar ends to those above described. In this

page_text: case the plate or frame f' is dispensed with, and the set screw d is placed in
front of the coulter in place of the back thereof. The projecting plate moves
on an axis or bolt, similar to what is above described, and has a bent plate ƒ³
formed thereon, which carries the plate f", which has a slot f" formed therein,
through which the screw fe passes, and by which it can be affixed to the beam
at any desired position. The set screw & which passes through the upper part
of the plate frests on the beam of the plough, and thus determines the
position of the coulter blade in respect to its being more or less vertical; its
distance from the beam is regulated as before. Figure 6 shews a plan, and
Figure 7 a side view, of a mode of regulating the position of the coulter, so far
as regards its departure from a vertical position, and also its distance from the
the beam. In this case the coulter is applied to the beam of a plough by
means of a sliding socket j, which has a set screw k, by which it can be made
fast to any desired part of the beam a, and the coulter is made fast to a pro-
jecting angular-faced plate k' by means of a clamp 7, such clamp consisting of
a plate bent at right angles at top and bottom, and having two recesses m, m,
formed therein, and two set screws n, which have each an eye to receive the
stem of the coulter; and by means of screw nuts n', n³, the screws n draw
the stem of the coulter against the angular face of the plate k', and accordingly
as the upper and lower nuts n¹, n', are screwed up more or less tight, so will
be the position of the coulter in respect to its being more or less approaching
a vertical position, and its distance from the beam will be regulated by the
position it is fixed at on the plate . Figure 8 shews a front view of another
arrangement of parts for applying a coulter to the beam of a plough, where
the degree of inclination from a perpendicular position is required to be
adjusted, as well as the distance from the beam; Figure 9 shews a side view
of the socket separately; Figure 10 shews a front view of the socket separately;
and Figure 11 shews a side view of the parts with a coulter appplied to a
beam of a
plough. On the socket is formed or affixed a projecting plate, on
which slides a plate i, similar to what has been already described, with a clamp
and set screw for affixing the coulter thereto; but it will be seen that the
socket, in addition to being able to slide along the beam a and be affixed
thereto by a screw, has also the capability of rocking thereon, owing to the
figure of the socket, by which, and by the set screw d, the inclination of the
coulter can be regulated. Figures 12 and 13 shew another arrangement of
means of applying a coulter to a plough beam. o is a clamp, which is capable
by means of a screw p of fastening the coulter to any desired position on the
beam a, and it is capable of being caused to stand out at an angle more or
less from the beam by means of the sliding plate q, which has a recess formed

page_text: therein to receive the stem of the coulter; and it will be seen that there are
two set screws, which, passing through the plate y, come against the beam a,
and cause the lower part of the plate q to stand off from the beam, and con-
sequently the coulter will also be caused to stand off at an angle to the
beam.
Having thus described the nature of our Invention, and the manner in which
the same is to be performed, we would remark that we make no claim to any
of the parts separately, many of which are well known, nor do we confine
ourselves to the precise form thereof so long as the peculiar character of our
Invention be retained; but what we claim is,-
First, the modes herein described of applying coulters to ploughs, whereby
we are enabled, by means of clamps and screws, to regulate the distance of
the coulter from the beam, and also the angular positions of the coulter, as
described in respect to Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.
And, secondly, we claim the mode of applying a coulter as shewn and
described in Figures 12 and 13, whereby the coulter is caused to stand off at
an angle by means of set screws and plate q.
In witness whereof, 1, the said William Williams, have hereunto set my
hand and seal, this Third day of February, One thousand eight hundred
and forty-one.
