Improvements in Ploughs.
We, JOHN MURRAY, of 35 Pollock Street, Glasgow, Dairyman, and JOHN HAY,
of,318 Paisley Road, Glasgow, Engineer and Pattern Maker, both in the County of
Renfrew, North Britain 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 :-
This invention relates chiefly, but not solely, to new and improved methods and
means for angleing certain moveable parts of an agricultural plough.
It also embraces methods and means for removing and replacing the point of a
plough Sock, from time to time as the point becomes worn out with use.
The three parts which are affected, principally, by this invention, are, the Coulter,
Sock and plough Head.
The Coulter and Sock are rendered adjustable at any required angle by the method
and means which we have devised. Hitherto the plough Sock could not be angled
(at will) by the ploughman but required forging, or bending, by a Smith if a variation
of its angle was required.
The "Coulter of a plough has hitherto been more or less capable of adjustment at
different angles but only by means of wedging it within the Socket provided for it in
the Beam of the plough or by re-forging it: and one of our improvements consists in
angling the said Coulter without removing it from its Socket in the Beam.
We effect this adjustment, first. by making the Coulter in two or more parts,
(a lower and an upper one); the lower part being capable of separation, at will, from
the upper one (which is tightly fastened in the Beam of the plough) and these two
portions are fixed together at any required angle, by the aid of screws and wedges, or
other agents.
The Coulter is, or may be, rendered adjustable, further, by hingeing the upper part
of it to the lower one and providing wedges and screws for adjusting the lower part
at any required angle to the upper part.
These two portions of the Coulter are, or may be, adjustable, other than, and in
addition to, angleing them as above named. This is effected by making the bolt holes
in each half of the Coulter Knee of an oblong form and in horizontal positions, so
that the lower part, or blade, of the Coulter may be projected forward or backward as
required and retained there by the same bolts which are used for angleing the said
portion of the Coulter.
The method and means which we have devised for rendering the plough Sock
adjustable at any required angle are, first, the provision of a rounded, conical pin or
point to the plough head (to which member the Sock is ordinarily fitted) and second,
the provision of a hole of corresponding shape (rounded and tapered to suit the pin)
in the heel of the Sock; these parts are united, and fixed together with a pinching pin
screw or other suitable means or appliances, for adjusting the Sock upon the rounded
conical pin at any required angle.

page_text: The shape of the pin which has heretofore been used upon the plough head for the
purpose of fixing thereon the plough Sock has been, more or less, angular in Section
and the hole within the heel of the Sock corresponded thereto; the Sock being, as a
consequence, incapable of adjustment except by forging or bending the blade thereof,
when hot.
In, and by, the method which we have devised the ploughinan may adjust the Sock
of his plough as often and as variously as he requires by simply relaxing the screw or
other agent which fixes the Sock upon the conical end of the plough head.
The moveable point of the plough Sock is constructed, adjusted and operated as
follows; we provide a small steel or metal point (either cast or wrought but preferably
cast) which has on one part of it a dovetailed (or other shaped) tongue or projecting
tab, which tongue is fitted (preferably but not necessarily from the under side, into a
corresponding socket, of a dovetailed or other suitable form, in the toe of the Sock.
This point is fitted firmly into the dovetailed or other shaped hole in the toe of the
Sock by the following means: Where a moveable point is used such as above described,
we expand the toe of the Sock by heating it and then insert the small steel or metal
point (which is not heated) in the socket within the toe and allow the Sock to cool and
contract upon the cold steel point; by this means the point is held rigidly in the end
of the Sock until the ploughman wishes to replace it with a new one when it may be
easily removed.
The tongue and its socket being made suitable in size for this method of attachment,
as a variation of these members for uniting the loose point to the Sock, the hole may
be in the loose point and the tongue upon the toe of the Sock, each part being shaped
as before described.
We also contemplate making the hole in the nature of a pocket, open at one end
only, and the tongue corresponding to it in form, its shape being either round,
elliptical or angular.
The accompanying series of diagram's will serve to illustrate our invention and
enable it to be more readily understood and more easily carried into effect.

Fig. 18 is a side elevation of a Sock.
Sheet 5 contains Figs. 19. 20 and 21.
Fig. 19 is a side elevation of a Coulter shewing a different method of constructing

Although the hole shewn here in this wedge shaped washer is square, we purpose
in some instances to make the Hole round or any other shape which may be most
convenient.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed, we declare, that what we claim is,
First, in an agricultural Plough the method of making the Coulter in two principal
parts substantially as, and for the purposes herein described and shewn.
Second, in an agricultural plough the method of making the two principal parts of
the Coulter herein described and shewn, adjustable by means of wedge shaped washers,
as herein described and shewn.
Third, in an agricultural plough the method of making the two principal parts of
the Coulter herein described, adjustable by means of oblong slots or holes in the Knee
parts thereof, substantially as, and for the purposes herein described and shewn.
Fourth, in an agricultural plough, the method of making the steel or metal Sock
thereof adjustable at any required angle by means of a rounded conical pin or end
attached to the plough head or other convenient part thereof and fitting the Sock
thereon, substantially as herein described and shewn.
Fifth, in an agricultural plough the method of renewing the point of the Sock
with a removeable piece constructed and attached substantially as herein described
and shewn.
Sixth, in an agricultural plough the method of fastening the detached point to the
Sock or the Sock to the conical pin by expanding and shrinking the reciprocating
parts substantially as herein described.
