PROVISIONAL SPECIFICATION.
A Device for Controlling the Pasturage of Animals.
I AUGUSTIN LEBOURG of Sassetot le Mauconduit in the Republic of France, Manu-
facturer do hereby declare the nature of this invention to be as follows:-
The object of this device is to obviate the necessity of an attendant to control the
pasturage of animals.
The device comprises a box with wooden ribs and zinc covering and having a
door at each end. It contains the mechanism hereinafter referred to:
On arriving at the pasturage the piquet is driven into the ground and the box set
on the head of the piquet which is secured by an iron clasp, one of the doors is opened
and the rope is wound upon a double wooden drum by means of a hand crank.
On
the one side is also an iron hook which may be set to give the animal a double allowance
by being pushed to the right or to the left. On the other side is a regulator to give
the desired velocity. There is also a dial, notifying by the aid of a pointer the
times of stopping the machine. This stopping is done by a hook with two teeth.
When the animal pulls on the cord the machine starts again but after the lapse of a
quarter of an hour is again stopped.
These stoppages of the machine occur thereafter every hour or every two or three
hours according to the velocity of the machine.

COMPLETE SPECIFICATION.
A Device for Controlling the Pasturage of Animals.
I AUGUSTIN LEBOURG of Sasselot le Mauconduit in the Republic of France, Manu-
facturer 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:-
This invention consists in a machine or apparatus to which the rope by which an
animal is tethered in a pasturage is connected in such a way that at certain intervals
of time, the pulling of the animal on the rope shall result in the drawing out of a
certain amount of the rope by which arrangement the circle of pasturage over which
the animal may feed is from time to time increased, and the pasturage of the animal
thus controlled automatically without necessity of an attendant to lengthen the tethering
rope at intervals.
The machine is to be fixed in place by a picket P and consists principally of a
casing A enclosing and protecting the mechanisin, of a clock work B which is in
the first instance wound up by hand by means of the band crank C, and afterwards
automatically wound at intervals by the movement of the animal drawing off the
tethering cord from the drum, of a disengaging device which is operated at the
intervals of time desired by means of the clock work and the pulley or drum D on
which the tethering cord is wound.
Reference being made to the accompanying drawings

Fig. 8 illustrates in elevation and plan the drum D for the tethering rope and pawl
therefor.
Fig. 9 is a perspective view of the disengaging gear and of the drum. D:
The animal being on the pasture, the machine is secured by means of the picket
and the animal is tethered to the end of the cord E which is wound on tho
drum D.
The cord will be unwound only by pull of the animal and that at the time when the
clockwork shall have operated the disengagement of the gear which locks the drum.
When the drum is turned by the unwinding of the cord the clockwork is wound up at
the same time by the pulley being on the arbor of the lever which carries the spring
pawl which engages in the teeth of the barrel and winds up the spring of the clock-
work. The drum is stopped by the arm U which touches the rocking plate J.
The clockwork being in motion operates the crank M so as to move back and forth
the rod L which is connected to the said crank and to the frame K having a toothed
or graded plate K', on one of the steps of which rests the arm J of the plate J
(see Fig. 9). The rod L moves the frame K which rocks the plate J causing the
nose to be periodically disengaged from or carried out of the path of the arm U.
The drum is therefore free to rotate in the direction for unwinding the cord and ou
the next pull given by the animal thereafter to the cord a further length of cord
corresponding to a half revolution of the drum is released.
The opposite end of the
arm will then arrive against the plate J and stop the further unwinding of the
drum. An indicator H serves for regulating the speed of the balance N by means of
the fork or bracelet G which limits the motion of a vibrating lever which moves the
balance. The indicator V shows the position of the crank M at any time.
To provide for the locking of the drum against accidental rewinding of the cord
and to enable the drum to be released from this contrivance when it is to be
rewound by hand; the door O which is to be opened to obtain access to the
handcrank C is attached to one arm of the bell crank lever Q by the rod S so that
the opening of the door moves the said lever, the other end of which then presses the
pawl R away from the plate R' on the drum, and the latter is free to be rewound
or moved in either direction. When the door is shut the spring T presses the
pawl R into the path of the plate R' so that while the bevelled shape of the ends of
this plate permit the drum to be revolved in one direction the latter cannot be
revolved in the other direction. The lever operates the lock P¹ by the pro-
trusion of which the finger J2 may be locked in connection with the arm U if
needed at any time. The notched plate P2 holds the lever P in either the position
of action or inaction. The hole in the case through which the picket passes may be
closed by a slide X when not in use.
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.
For controlling the pasturage of an animal
1. A device in which the tethering cord is gathered and held and released at intervals
so that it may be drawn out for a certain length after such release.
2: A machine comprising a dium D for receiving a tethering cord E in combination
with a clockwork, a locking device by which the drum is released at intervals and
again locked after a certain amount of revolution substantially as and for the
purpose set forth.
