Improvements in Clipping or Shearing Instruments and Apparatus
in Connection therewith.
We, LOUIS FERDINAND JULES BARIQUAND, EMILE BARIQUAND and CHARLES PIERRE
EUGENE MARRE all of 23 Boulevard de Strasbourg, Paris, France, Manufacturing.
Engineers 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 :-
In the Specification to a former Patent, No. 3674 of 1883, we have described an
improved construction of clipping or shearing instruments whereby the moveable comb
was actuated by mechanical power instead of by hand.
The general construction of our present improved instrument is similar to that
described in the said Specification, but the fixed lever of that arrangement is in the
present case made to form the body of the instrument and the moveable lever has the
required motion mechanically imparted to it, which it transmits to the moveable comb.
The improved instrument consists of three main parts:
1. The clipping or shearing instrument itself which is adapted to be held in one
hand and to be actuated by a motor.
2. The transmitting device which is connected at one end to the motor and at the
other end to the clipping instrument, and which is sufficiently flexible to allow of the
clipping instrument being used in any direction or position, the motor remaining
fixed.
3. The motor, which is actuated either directly by hand, or by gearing or by steam
or other power.
The clipping instrument is shewn in side view at Fig. 1 and in plan at Fig. 2, in
longitudinal section on line A B at Fig. 3, in sectional plan on line CD at Fig. 4,
and in cross section at Fig. 5.
The handle A forms the framing of the instrument; the lever B B constituting the
moving part is pivotted on the axis R; the comb Fcarries the counter comb H guided
by the tenons T, and D is the fixing bolt. The body or frame A is fixed on the end
of a handle held in the hand. The moveable lever B can be actuated in various ways:
D

page_text: Figs. 1 to 8 shew an arrangement for actuating it by an endless cord or band X
passing round a grooved pulley P on an axis I fixed to the frame A, which pulley P
has an eccentric projection which imparts a to and fro motion to the lever Bat
each revolution. The cord is led through a flexible tubular guide Z to a driving
pulley Y Figs. 7 and 8, the guide Z being attached at one end to the handle of the
instrument and at the other end to the bracket of the pulley Y; it is conveniently
formed of two wire helices either fixed together at intervals or enclosed in an outer
covering as shewn.
Thus the leading part of the cord passes down one tubular passage while the
following part passes down the other.
Other arrangements may however be used.
The pulley may be driven by any convenient power, such as from a mill shaft as
indicated at Fig. 8. The connection of the tubular guide Z to the bracket of the
pulley Y is effected by a slotted piece with screw bolt, so that by adjusting the latter
the cord can be tightened round the pulley Y for affording the requisite grip. Instead
of working the instrument by means of a cord having continuous motion in one
direction as described, the cord may be in two separate lengths, having a to and fro
motion imparted to them by means of a reciprocating double ended lever to which
their one end is attached, the other end being attached to a sway beam on the
instrument, the to and fro motion of which is imparted to the lever B.
The arrangement of endless cord with continuous motion is however preferred.
Figs. 9 to 15 show an arrangement for working the clipping instrument by means
of compressed air.
Fig. 9 shews a side view of the instrument, Fig. 10 is a plan, Figs. 11, 12, 13
respectively two longitudinal sections at right angles to each other, and a cross section
through the handle.
The moveable lever B of the instrument has a stud J pivotted to a piston Q receiving
a to and fro motion in a cylinder R forming part of the body of the instrument. The
ends of the cylinder communicate by tubes S passing through the handle and having
flexible extensions, with the ends of a cylinder T constituting the motor, and containing
a piston to which a to and fro motion is imparted by power or by hand.
The air being thus alternately compressed and expanded on each side of the piston,
a corresponding motion is imparted to the piston of the instrument through the
medium of the air in the tubes S. Instead of air, any other suitable fluid or liquid
may be employed.
In order to enable the movement to be stopped at will when the apparatus is driven
by a cord as first described, the stud R. Figs. 2 and 3 is connected to the eccentric fork
of a lever L so that by raising the latter the stud is drawn out of gear with the lever B,
so that this being deprived of its fulcrum, it will cease to impart its motion to the
counter comb. When using the arrangement with air transmission, a cock is provided
on the air passages S at the bottom of the handle, as shewn, so that by turning the
cock into the closed position, the piston Q will cease to be actuated.
The shearing of animals, in particular of sheep, when carried out on a large scale,
may be effected in two ways; either the flocks are brought to shearing works having
a suitable installation with motive power, or the necessary apparatus is conveyed to
the locality where the flocks are situated. In the first named case the mode of trans-
mission by means of a cord as described with reference to Fig. 8 may be advantageously
employed, the motive power being thus arranged at a sufficient height above the ground
to give free room for the shearing operation below, thus avoiding all complication of
transmission, and allowing of the arrangement of any desired number of shearing
instruments along the line of shafting. In the second named case, the air transmission
may be advantageously used, the motor cylinders T being arranged on each side of a
truck carrying suitable hand driving gear as shewn at Fig. 15, and which can be readily
conveyed from one locality to another. This arrangement of truck or framing on
wheels can also have the transmission by cord applied to it, and the air transmission
might also be driven by power at the shearing works, but the arrangements are by
preference employed as described.

page_text: In order that the screw nut of the shearing instrument may not project and thus be
liable to catch in the wool of the animal operated upon, we employ by preference the
construction of screw bolt and nut shewn to an enlarged scale at Figs. 16, 17 and 18.
The nut is here made with a sufficiently deep and wide notch to allow of any piece
of metal, such as a large coin being inserted and used as a key for screwing or
unscrewing.
For preventing the loosening of the nut, the bolt may be partly slotted, as shewn at
Fig. 9 for the reception of a plate b, acted upon by a helical spring, so as to enter
serrations d on the underside of the nut.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Imparting motion to the counter comb by a cord transmission passing over a
pulley having an eccentric boss that imparts a to and fro motion to the actuating lever
at each revolution, substantially as herein described with reference to Figs.
to 5.
2. Imparting motion to the counter comb by means of a piston in a cylinder on the
clipping instrument which cylinder is connected by tubes to a second fixed cylinder
whose piston is worked to and fro by hand or by power, thereby imparting motion to
the piston in the first cylinder, substantially as herein described with reference to
Figs. 19 to 24.
3. Apparatus for clipping or shearing animals consisting of a truck or framing on
wheels carrying a motor or driving gear worked either by power or by hand and
combined with clipping or shearing instruments by suitable transmission appliances,
substantially as herein described with reference to Fig. 15.
