I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son,
of No. 11, Wellington Street, Strand, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF PLOUGHS," a communication
to me from abroad by Jean Pierre Lattes and Raymond François
Fauré, both of 15, Passage des Petites Ecuries, Paris, France, to be
as follows:-
These improvements are illustrated on the accompanying Sheet of
Drawing forming part of this Provisional Specification, and consist in
a moveable share and mould board, in the application to the beam
and body or props united of a socket piece, double wings and of a
share M forming a Grecian plough, and to this same socket of a small
share K to form a grubber. The beam is of wood with two plough

page_text: handles or levers fixed by two bolts and nuts, the sole or slade and
body or stays forming a single piece; the two props have at the top
two tenons which enter the wooden beam, and are there finally fixed
by two strong bolts and nuts. The sole carries a pivot front and back.
The pivot A enters into B which is a hole made under the fore part of
the mould board, and the hole at the back receives the pivot C which
is at the extremity of a support or buttress having two branches at the
other end, each of which has at its end a cramp iron No. 1 hooking
the mould board by means of two fixed catch holes or staples No. 2.
The rod No. 3 which is held by one end fixed to a hole in the mould
board enters the hole placed before the spring of the branches of the
buttress, and is fixed there by a nut; it is this rod which keeps the entire
arrangement in position. The mould board being secured by the pivot A
and the hooks of the buttress is fixed to the right or left by means
of an upper hook beneath the beam and in front of the plough handles.
The share so constructed as to dispense with coulter is tied to the
mould board by bolts and nuts. The mould board, the sole or slade,
and body or props are of cast iron with steel plates riveted thereto.
To turn the mould board the upper

hook and the arms of the plough are removed and the mould board
turns on the pivots of the share; the hook is then replaced to keep
the mould board in its new position.
Pieces to be Substituted to Transform a Turn board Plough into a
Grecian Plough or into a Grubber.-The rod is unscrewed and the mould
board removed together with the share and buttress, the plough handle is
then inserted into the sole in the cavity of the socket picce, and the
screw of the bolt of the socket piece must enter the hole D of the
sole until these two pieces are firmly fixed. The tail of the share is
passed through the front of the socket piece, to the heel of which it
is fixed by means of a pin. The twin wings are then placed on the
socket piece and then fixed by means of a metal bar or strap fastened
to the socket piece, and a bolt passing over the wings enters a hole
of the strap and is then held by a long pin. To form a grubber the
share and the wings must be removed and the share K placed in the
socket piece.
