Invention of IMPROVEMENTS IN RIDGE-PLOUGHS, ALSO APPLICABLE TO OTHER
PLOUGHS communicated to him from abroad by Barthélémy Lanoizelet, of
Bourbon-Lancy, France,
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 3rd March 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN RIDGE-
PLOUGHS, ALSO APPLICABLE TO OTHER PLOUGHS," a communication to me from
abroad, by Barthélémy Lanoizelet, of Bourbon-Lancy, France,
This invention has for its object the construction of an improved ridge-plough
for the earthing up of the ground for the purpose of sowing cereals and principally
for planting potatoes.
The ridge-plough comprises chiefly a bent piece of iron forming the beam of the
plough and provided at one end with a socket adapted to receive a handle or a
swingle-tree, while a share made of steel is attached at the other end.
Also attached to the beam, by means of bolt and pin, are two mould-boards
made of iron plate.
The plough is further provided with a peculiar device for the purpose of setting
the mould-boards more or less apart according to requirements.
This setting device consists of two slotted iron bars, fixed horizontally across the
beam by means of a thumb-screw.
The plough is adapted for hand-use as well as for being drawn by an animal; in
the latter case a suitable socket for receiving the handle may be fastened to the
beam by means of thumb-screws.
The plough may be constructed in a larger size so as to serve as an ordinary
plough.
In this case it may be provided with an additional share, fastened to the beam
by suitable means; also with a post carrying at its lower end a roller and provided
with a series of holes for the purpose of fixing the post to the beam at different.
heights and thereby regulating the depth of the furrows.
The beam may either be made of one piece bent at an acute angle or into an
upright horse-shoe shape, or it may be made of two parts, a lower one and an upper
one, the mould-boards being secured between them,

by the said Herbert John Haddan in the Great Seal Patent Office on the

HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN RIDGE-
PLOUGHS, ALSO APPLICABLE TO OTHER PLOUGHS," a communication to me from
abroad by Barthélémy Lanoizelet, of Bourbon-Lancy, France,
The principal object of this apparatus is to furrow the ground for the purpose of
sowing cereals, for instance corn, maize, beans and potatoes. This plough is an
advantageous and economical substitute for all others hitherto in use for such
purposes, especially for planting potatoes.
The ridge plough, as illustrated in the accompanying drawing, comprises chiefly
a piece of iron A forming the beam, and provided with a socket L adapted to
receive a handle T, Fig. 1, or a swingle-tree K, Fig. 2. F is a movable steel share
affixed by means of two screws E.
B are two mould boards of iron plate, attached to A by means of peg M and a
bolt N. The distance between these two boards B is made adjustable by means of
a regulator consisting of two slotted iron bars C, fixed horizontally across the
beam by means of a thumb screw D. These two boards can be easily exchanged
for others if required. An iron socket piece G, fixed to the beam A by means of
the thumb-screws D and H, Fig. 2, receives a wooden handle T for guiding, when
the plough is drawn by a light animal. I is a ring receiving a hook of the trace-
bar K. This ring is held fast inside the socket G₁ by means of a wooden packing,
by the bolt L'.
Figs. 3 and 4 show an apparatus for extensive agriculture. It comprises the
same parts as the plough illustrated in Figs. 1 and 2. The only additional part is
a single or double shaft to guide the plough. P is a movable heel, protecting the
beam against wear.
The front part of the plough is protected against obstructions of earth by means
of a knife q inclined as may be required and then fixed to the body of the plough
by means of a strap R tightened with two screws.
The part. S fixed in a mortice serves as a regulator and is provided with a
wheel Fig. 3 or with a chain V¹ fig. 4.
In Fig. 3 the trace-bar is hooked to the hook. G¹, while in Fig 4. it is hooked
CLAIM.
The arrangement and combinations of the different parts of the apparatus as
above described and illustrated, which apparatus is principally adapted to furrow
the earth, for sowing cereals of all kinds, and to be drawn by a man or by an
animal.
In Witness whereof, I, the said Herbert John Haddan have hereunto set my
hand and seal this 3rd day of September A.D. 1883.
