GEORGE WRIGHT CHAMBERS, of Staplehurst, in the County of Kent, Farmer.
"IMPROVEMENTS IN THE CONSTRUCTION OF PLOUGHS AND OTHER AGRICULTURAL
MACHINES OF AN ANALOGOUS CHARACTER."
This Invention consists in improvements in the construction of ploughs, machines
for "banking up" hops and turnips, and other agricultural machines of an analogous
character, by means of which the shares or corresponding parts thereof may be tilted
or moved to a position at an angle to that normally maintained without the front
wheel or wheels being caused to partake of the said movement.
I will proceed to describe the nature of my improvements as applied to ploughs.
The beam of the plough is divided into two parts at that portion thereof which
is situated between the front wheel or wheels and the share or shares. The said
two parts are connected together in the following manner:-
To the end of one portion of the beam is or are attached two or more projections
having circular eyes or holes therein, through which the rounded end of the other
portion of the beam is passed, and is prevented from becoming detached by means
of pins or other contrivances; or the end of one portion of the beam is enlarged, in
the centre thereof being a circular hole running longitudinally, and sufficiently
large in diameter and length to receive the rounded end of the other portion of the
beam, ineans being provided to prevent the disconnection of the two parts. Both
the above described arrangements admit of a slight turning or twisting movement
of that portion of the beam to which the handles and shares are connected,
thus allowing the man in charge to move the latter to one side or the other
(suitable stops being provided to limit the action) as may be desired without
affecting the position of the front wheel or wheels, which is or are thus permitted
to continue travelling in a straight line, whilst in ploughs of ordinary construction
the front wheel or wheels is or are tilted with the remainder of the machine, and
has or have consequently a bias to move to one side.
Although in the above description certain methods are alluded to for connecting
the two portions of the beam it is not intended to confine this Invention to the

page_text: employment of those methods, as any suitable and known contrivance capable of
effecting the same purpose may be used.
In order to facilitate the turning of the front wheel or wheels the vertical rod by
which the axle thereof is supported passes through an eye or hole in the end of the
beam in such a manner that on the horses (which are connected to the said vertical
rod) moving in a certain direction the said vertical rod and wheel or wheels will be
turned in the same direction.
When two wheels are employed the lower end of the before mentioned vertical
rod through which the axle passes may be provided with a joint, so that one wheel
can be at a greater elevation than the other without in any way interfering with
the vertical position of the said rod.
My Invention is applied to agricultural machines other than ploughs in a manner
similar to that above described, as will be well understood. .
