WHEREAS His most Excellent Majesty King George the Third, by His

the said James Smart, his executors, administrators, and assigns, and every
of them, by himself and themselves, or by his and their deputy or deputies,
servants, or agents, or such others as he, the said James Smart, his executors,
administrators, or assigns, should at any time agree with, and no others, from
time to time, and at all times thereafter during the term of years therein

"MAKING A PLOUGH SHARE AND SHARE BED," within that part of His Kingdom
of Great Britain called England, His Dominion of Wales, and Town of
Berwick-upon-Tweed, in such manner as to him, the said James Smart, his
executors, administrators, and assigns, or any of them, should in his or their

page_text: and during the term of years therein mentioned; and it is by the said in part
recited Letters Patent (amongst other provisoes therein) provided, that if the
said James Smart should not particularly describe and ascertain the nature of
his said Invention, and in what manner the same is to be performed, by an
instrument in writing under his hand and seal, and 'cause the same to be
inrolled in His Majesty's High Court of Chancery within one calendar month
next and immediately after the date of the said Letters Patent, then the
said Letters Patent and all liberties and advantages whatsoever thereby granted,
should utterly cease, determine, and become void, anything therein contained
to the contrary thereof in anywise notwithstanding.
NOW KNOW YE, that the said James Smart, in compliance with and in
performance of the conditions in the said proviso contained, doth hereby
declare that the nature of his said Invention, and the manner in which the
same is to be performed, are particularly described and ascertained by the
Drawings in the margin of these Presents, and by the explanation thereof
herein-after given and contained, in which Drawings Fig. 1 is a plan of the
ploughshare as it lays on the ground when the plough is used, in which the
letter A represents the face of the share (in Fig. 1 and 2), which is in a bevel
line flush with the turnfurrow, and the share is hollow underneath, as in Fig. 7
and 8. Fig. 2 is a plan of the share joined to the share bed, laying in the
same position as in Fig. 1. The top edge of the share bed for the length 8, 8,
in Fig. 2 and 3, is made with a projecting tongue on the inside face, as 8 in
Fig. 6, and the bottom edge for the whole length, with another tongue 9, 9,
in Fig. 2 and 3, projecting as in 9, 9, Fig. 5 & 6. The share bed is in other
respects a flat plate. These tongues form the share bed into an open groove,
in order to receive and fix the shank of the share therein, see 8, 2, 9, in Fig. 3,
and 8, 6, 9, in Fig. 6. The bottom tongue or shoe part of the bed
may be
made narrower or wider,, according to the nature or quality of the ground in
which it is to be used. Fig. 3 is a view of the inside face of the share bed
which fixes on the chip or sheath of the wood frame of the plough, with the
ploughshare laid therein. Fig. 4 is a view of the outside face of the share
and share bed, being quite flat. Fig. 5 is a section across the share. bed from
B to C, in Fig. 3 and 4. Fig. 6 a like section from D to E in Fig. 3 and 4,
showing the shank and wedge of the share. Fig. 7 is a section across the.
ploughshare from F to G in Fig. 3. Fig. 8 a like section from H to I in
Fig. 3. Fig. 9 a like section from K to L in Fig. 3. The three last sections
shew the manner in which the share encreases its size from the point towards
the shank, where it joins to the turnfurrow when fixed to the plough. The
1 Figures 1, 1, 1, of Fig. 1, 2, and 3 represent a hole in the upper part or
small

to hold the share up to the main beam of the plough... 2 in Fig. 1 represents.
the uppermost edge of the.shank. 2 in Fig. 3 représents the flat side of the
shank .as it lays in the share bed between the tongues, or in the.groove:
between 8 and 9. 6 in Fig.6 shews the extremity of the shank as it lays in
the share bed, and 6 in Fig. 7 shews.the shank at the section G, F, in Fig. 3.
3, 3, 3, 3, in Fig, 1, 2, 3, and 4, represent the nose or point of the share; but
light ground does not require a share with a nose; and therefore they may be
made without a nose, as shewn or represented by the dotted lines on the same
Figures. 4, 4, 4, in Fig. 3, 4, & 6, and 5, 5, 5, in Fig. 3, 4, and 5, represent the
holes for bolts to fix the share bed on the chip or sheath of the wood frame of
the plough. 6, 6, in Figures 6 and 7 is the section of the shank of the share,
which is driven close and fixed by the wedge. 7 in Figure 3 represents an iron
wedge driven between the shank of the ploughshare and the tongue 8, 8, in
Fig. 3 and 6 of the share bed, in order to fix the share in the bed before it is
screwed on the wood frame of the plough; and this wedge may be driven on
either side of the shank so as to raise or fall the nose or point of the share,
but the shanks may be made strait so as to slide into the share bed flush
between the tongues, and by that means may be fixed without a wedge. 7 in
Figure 6 shew the position of the wedge at the section D, E, in Fig. 3.
10, 10, 10, in Fig. 2, 3, and 4, represent a hole or notch in the face of the share
bed to receive a strip or piece of iron which ties or fixes the bottom frame of
the plough to the main beam, but such share bed may be made without a hole
or notch. The several articles of this Invention may be made in cast or
wrought iron or steel, or any other hard metal. The Drawing of the share
bed is coloured blue, the wedge yellow, and the share uncoloured.
In witness whereof, the said James Smart hath hereunto set his hand
and seal, this Sixteenth day of May, in the year of our Lord One
thousand seven hundred and ninety-two.
Sealed and delivered by the within-
named James Smart, being first duly
stampt, in the presence of
JAMES (L.s.) SMART.
