AN APPARATUS TO SHEAR DOMESTIC ANIMALS
Year: 1859

page_text: LETTERS PATENT to Xavier Carrère de Nabat and Armand Carrière de
Nabat, of No. 41, Rue d'Angoulême St. Honoré, in the City of Paris,
Empire of France, Gentlemen, for the Invention of "AN APPARATUS TO
SHEAR DOMESTIC ANIMALS."
PROVISIONAL SPECIFICATION left by the said Xavier Carrère de Nabat
and Armand Carrère de Nabat at the Office of the Commissioners of
Patents, with their Petition, on the 27th December 1859.
Wo, XAVIER CARRERE DE NABAT and ARMAND CARRÈRE DE NABAT, of
No. 41, Rue d'Angoulême St. Honoré, in the City of Paris, Empire of
France, Gentlemen, do hereby declare the nature of the said Invention for
"AN APPARATUS TO SHEAR DOMESTIC ANIMALS," to be as follows:-
The apparatus by which we propose to shear domestic animals, more
especially horses, asses, and cattle, consists of two metal supports screwed the
one to the other; in these supports is placed a shaft square at one end and
carrying at the other a toothed wheel gearing into a pinion fixed upon another
shaft, this shaft carrying two plates or wheels with arms having slits in them,
in which the ends of steel blades are secured by press screws. These blades
rub against or form scissor with a lower blade basiled and well tempered.
This latter blade is attached to the two supports by two pivots, and beneath is'
a metal comb furnished with a spring, which tends to raise the said blade,"

page_text: the comb being screwed to the supports. The apparatus, when used, is to be
held in one hand, while the other, by means of a "Breguet " key turns the
first-mentioned shaft, and thus every part of the animal may be passed over
and shorn close or otherwise at will, the length of the cut being regulated by
the thickness of the comb.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Xavier Carrère de Nabat and Armand Carrère de Nabat in
the Great Seal Patent Office on the 27th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, XAVIER
CARRERE DE NABAT and ARMAND CARRERE DE NABAT, of 41, Rue d'Angoulême
St. Honoré, in the City of Paris, Empire of France, Gentlemen, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Xavier Carrère de Nabat and Armand Carrère de Nabat, Her special
licence that we, the said Xavier Carrère de Nabat and Armand Carrère de
Nabat, our executors, administrators, and assigns, or such others as we, the
said Xavier Carrère de Nabat and Armand Carrère de Nabat, our executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise and vend, within
the United Kingdom of Great Brittain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "AN APPARATUS TO SHEAR DOMESTIC ANIMALS,"
upon the condition (amongst others) that we, the said Xavier Carrère de
Nabat and Armand Carrère de Nabat, our executors or administrators,
by an instrument in writing under our, or their, or one of their bands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the dato of the said Letters
Patent.
NOW KNOW YE, that we, the said Xavier Carrère de Nabat and Armand
Carrère de Nabat, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and

page_text: ascertained in and by the following statement, reference being had to the
Drawing hereunto annexed and forming part of this our Specification, and tỏ
the letters of reference marked on the several diagrams denoting similar parts,
where such parts appear or can be seen at each of the Figures respectively, in
which said Drawing Figure 1 represents a plan view of the entire apparatus,
showing at one view all the parts which can be seen in plan; Figure 2, plan of
the axle, cylinder, pinions, rundle, toothed wheel, and pinion; Figure 3, plan
view of rack and pinion; Figure 4, plan view of cylinder; Figure 5, elevation
of catch or stop pinions and rundle; Figure 6, elevation of the blades X, X;
Figure 7 elevation of the blade D; and Figure 8 elevation of the comb.
The apparatus detailed in the following description is used for clipping or
shearing the hair or wool from domestic animals, and is more especially useful
in effecting this operation on the hair of horses, asses, and cattle, but, as before
stated, may be made usefully available in shortening the hair or wool of other
domestic animals, the which it effects in a small (comparative) period of time:
It is well known that the operation of clipping a horse occupies the time of a
man using the usual shears or clipping scissors from a day and a half to two
days, and where great care is required even more. With our apparatus the
result may be obtained in from three to four hours, and the operation per-
formed in a more even and satisfactory manner.
Our apparatus is composed of various mechanical parts combined as
follows A, B, Figure 1 shews a pair of pincer or nipper handles working on
a spindle in the usual manner; to these are attached two supports N, N,
either made of one body or piece with the nipper handles or secured thereto,
through these supports an axle M (Figure 2) passes, furnished at one of it's
extremities with two pinions I and J, and a rundle F, which are fixed on the
axle (shewn at the same Figure); this rundle carries a stop or catch G (sco
Figures 1 and 5) which serves to gear into the pinions, and is so disposed as'to
allow the axle always to turn in the same direction only. The pinions I and J
are moved by a double rack A', A', Figures 1 and 3. At the other extremity
of the axle M is fixed a toothed wheel L, which puts in motion a pinion K,
the use of which is to impart motion to a cylinder C (Figures 1, 2, and 4);
this cylinder, which is composed of metal, is armed with two blades X, X, (sce
Figure 6) which may either be made in one body with the cylinder or
separately, and attached thereto. Beneath the cylinder is placed a fixed
blade D (Figure 7) which form "scissar" with the blades of or on the
cylinder C; on this last-mentioned blade D is fixed a comb E (Figures 1 and 8)
which serves to preserve the skin of the animal from cuts during the passage
of the apparatus over its body and the working of the blades, and also to

page_text: regulate the length of hair or wool which it is intended to leave on the bide or
skin. The cylinder may be sustained in position by fixed cushions or by
recall screws, or, if preferred, by two points in case of the cushions being fixed
or when the cylinder is supported by two points the blade D should then be
made moveable or grooved. The apparatus may be made with either a fixed
or moveable plate by turning the shaft with a crank handle or otherwise, or by
making it act forwards and backwards at will.
Having now described the the nature of our said Invention for shearing
domestic animals and the mechanical parts of which it is composed, we desire
it to be distinctly understood that we do not confine ourselves to the precise
details thereof, or to any relative proportions of parts to other parts of the
apparatus; nor do we lay any claim to any of the said parts of mechanism
when not put together or combined according to our directions or used for the
purposes of our Invention; but we do claim as of our Invention the com-
bination of mechanical parts forming, when combined, "An Apparatus to
Shear Domestic Animals," as herein-before described, detailed, or illustrated
in the Drawing.
In witness whereof, we, the said Xavier Carrèro de Nabat and Armand
Carrère de Nabat, have hereunto set our hands and seals, this
Twenty-first day of June, in the year of our Lord One thousand eight
hundred and sixty.
Witness,
H. BOURLY.
