PROVISIONAL SPECIFICATION.
An Improved Plough.
I, ALBERT BOULET of 31 Boulevard Henri IV, Paris, in the Republic of
France, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improved plough dispenses with the traction of animals and steam power,
being operated by one or more laborers, by means of two cranked handles and a
series of multiplying wheels which rotate a geared chain-wheel, over which passes
a chain, one end of which is carried to the end of the strip of land to be ploughed.
The end of this chain is attached to a stake or stakes driven in the ground to
secure it.
The chain is kept tight over the chain wheel by means of pulley wheels, and a
spring or springs. The plough has the usual handles and front and back wheels,
and may have one or more shares. An eccentric fixed to the axle of the chain
wheel imparts an oscillating motion to the bar or bars which support the shares,
whereby they are caused to penetrate the soil and form the furrow.
The other end of the chain after passing over the chain wheel, can be wound on
a drum or carried behind the plough and attached to other stakes placed in the
ground to receive it.
My improved plough is especially suited for ploughing between rows of vines
or young plants.

COMPLETE
SPECIFICATION.
An Improved Plough.
I, ALBERT BOULET of 31 Boulevard Henri IV, Paris, in the Republic of France,
Engineer, 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 :-
The plough which is the subject of the present application for a Patent, is
designed to take the place of the horse plough, which it does advantageously and
economically, and it is claimed that it even excels that implement both as regards
power and in the ascent of steep ground.
I will now describe the invention with reference to the accompanying drawings,
in which
Fig. 1 shows a side elevation of my hand power plough, and Fig. 2 a plan view
of the same.
The plough shewn which may be varied in form is fitted with a stop-chain, with
double mould board. A is the first pinion operated by the cranked handles P, and
acts upon the large cog wheel B to which is attached the second pinion C which
operates the second cogwheel D. On the axle of D is fixed the chain pulley E.
This pulley is of varying size according to the required length of furrow.
Of course a plot of land of great length can if necessary be divided into two or
three portions, each of which can be operated on separately.
F is another pulley with smooth hollow periphery which serves to guide the
chain X on to E. G is another chain pulley on the top of. the support J, over
which the chain ✗ passes to raise it above the stocks of vines or other plants when
Paine Rd 1

page_text: necessary, as it travels over the pulley H, which is placed at the end of the hori-
zontal arm K.
From the pulley H the chain descends to the ground at the exact position where
the second furrow will be made.
The arm K is moveable in a space suitable to the vertical support J. This space
extends right and left so that it is adjustable for either side.
L is an adjustable back wheel which facilitates the passage of the plough, or
serves to maintain it in the position deemed suitable for its work.
O is a coiled tension spring acting on the chain X by means of the pulley I
which chain is thus held firmly in the chain prints of the pulley E.
P. P indicate the two handles which act on the first or initial pulley wheel A.
Qis a principal part of the frame attached to which are the following parts ;--
1. The bolt R holding the frame together.
2. The support S which binds the part of the frame Q to the handles of the
plough.
T is a guide for the chain in front of the plough.
V is a stay bar supporting the vertical rod J.
✗ is the working chain already mentioned.
Y Y are stakes holding the end of the chain firmly to the ground.
Z is a rod connecting the rack lever of the plough to the plate Z¹ and so forming
an eccentric which is fixed to the axle of the cogwheel B.
Because of this eccentric, the rod Z imparts to the lever a tangential movement
which is communicated to the end of the share of the plough, and it is this move-
ment which facilitates the penetration of the blade into the soil.
My hand plough is used as follows-
When it has to work amongst plants set on a slope in rows about 60 c/m apart;
after regulating the distance of the two mould boards and the position of the
plough by means of the small chain N, 1 place the implement on the lower side of
the slope, and on the left side of the operator when he faces the ascent. The
plough then occupies the exact middle of the interval comprised between the first
row of plants on his left and the second row of plants on his right.
I fix the chain X by means of the stakes Y Y. driven firmly into the soil at the
higher end of the first portion of the land to be worked. I then turn to right or
left the arm K with the pullies G and H, bearing the chain on the side nearest the
operator. I then make the chain descend to the earth, in the space between the
second and third rows of plants, and secure the end by two of the stakes.
Then placing myself between the plough handles b, which I guide thus without
impeding my arms, I seize the two revolving handles P, and turn the cranks
resolutely rotating the pinion A, and thus setting the train of wheels in motion,
including the chain wheel E, over which passes the large chain X.
The power so applied is so effective that the chain winds up around the
pulley E, and the plough advances with sufficient speed and regularity. When
arrived at the higher end of the piece of land, the stakes Y, Y, are removed
to the adjoining end of the third space. I then direct my implement into the
second space, and turn over the arm K, from right to left, and proceed as before,
until the entire piece of land is operated.
In order to transform the implement into an ordinary plough, it is only necessary
to remove one of the double mould-boards and chain, replace the share by an
ordinary share, when any kind of soil can be worked in the usual way.
Of course
in this case the upright bar J, and the arm K, are removed. The plough is guided
by means of the iron bar c, which is pivotted on to the middle arm of the
chain-support T, which embraces the wheel d and which is attached to the axle on
both sides. The bar C rises vertically a short distance then passes horizontally
beneath the hook e. It also extends longways beneath the back handles, passing
through a pivotted collar f. It then rises over the handles. During the motion
of the implement if the hind part of the rod is pushed to the right it turns
the front pivotally to the left, and thus guides the wheel and vice versa.

page_text: From the foregoing description it will be understood that although specially
designed to be worked by hand, a motor can be employed. B' shows the position
in which it can be carried, and the dotted wheels indicate the way in which the
power can be applied through a belt c³, and a pulley a³, which discharges the
function of the double handle P.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
(1). The mechanical device or arrangement for operating ploughs of all
kinds, and its application to all analogous implements, as herein explained and
set forth.
(2). The combination with my invention of any suitable motor, as herein
explained and set forth.
