page_text: WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN MEANS AND MACHINERY FOR CLIPPING HORSES AND OTHER ANIMALS," a com-
munication to me from Charles Courtois, a person resident at Mont-
rouge, in the Empire of France, Mechanical Engineer, and have
petitioned Her Majesty to grant unto me, my executors, administrators,
and assigns, Her Royal Letters Patent for the same, and made solemn
Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand. and
seal, fully describes and ascertains the nature of the Invention, and the
manner in which the same is to be performed, reference being had to
the accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
The Invention communicated to me relates to improvements in the
machinery for clipping horses and other animals at present composed
of a toothed plate or metal comb which is fixed and placed in the
necessary positions on the skin of the animal in order to raise the hairs,
and of another plate or toothed cutting piece which is caused to move
sideways in a direction transversal to the teeth of the first plate upon
which this second one is placed.
The said improvements consist in giving a circular shape to these
two plates, and instead of operating the upper one which performs the
clipping process by a side motion from right to left and from left to
right, as is now done, to operate it by a continuous rotary motion, which
can be directed in one direction or the other as desired by means of a
crank and intermediate gearings. The continuous rotary motion of the
upper plate, which is the one that outs off the hairs as stated before;
enables the clipping to be done with facility and rapidity, and at the
same time with neatness and regularity, without leaving those unequal
surfaces which every one now remarks after a clip has been executed by
any of the existing clipping machines of this kind.
The accompanying Drawing represents an instrument or machine
constructed and arranged with these said improvements. Fig. 1 is a top
view or plan thereof, and Fig. 2 a side view. In these two Figures the
same letters of reference indicate corresponding parts.
a is the underneath fixed plate; this plate has on a segment of its
circumference teeth that are straight or parallel with one another, that
is to say, not cut in the direction of the radii from the axis on which

page_text: the pin d rivetted to the
placed a toothed wheel e,
the upper plate turns. It is provided with a handle b, which serves to
direct the machine over the body of the animal. c is the upper revolving
plate. It has on the whole of its circumference teeth, which on the
contrary are cut in the direction of the radii of its axis, that is to say,
non-parallel with one another. These teeth are quite flat underneath,
and rest on the lower plate a, they on the contrary are bevel shaped
above, and it is the two sides of the upper beveled surface which alono
should be ground for sharpening these teeth. The upper cutting plate c
has a hole in its centre through which passes
lower plate a. Above the cutting plate c is
through whose centre passes the pin d, and which has on its lower
surface two studs which fit into two corresponding holes in the cutting
plate c, so that these two pieces are dependent upon one another and that
the rotary motion given to the wheel is transmitted to the plate. Above
this cog wheel e and around the pin d is a spiral spring f, which is
more or less compressed by the screw nut g screwed upon the wormed
end of the pin and serving to press the upper plate against the lower, at
the same time giving a certain elasticity to the former. The rotating
motion is given as desired to the upper cutting plate in either direction
to the right or to the left, by means of the crank hand the intermediate
large toothed wheel e and the little one i, which is in gear with said
wheel e.
The little wheel i turns on an axis or pin j rivetted in the
fixed plate a, and it is maintained by a nut screwed to the pin whose
end is wormed. The upper moveablo cutting plate is slightly concave,
so that its teeth only bear on the lower plate a. The space resulting
from this concavity between the two plates not only prevents all friction
between them, but it also forms a reservoir for the oil necessary for
oiling the machine and for facilitating the sliding of the teeth of the
upper plate on the lower. This oil is introduced through a hole in the
upper plate c, and enclosed by the end of the little flat spring m.
Having thus described the said Invention, and the manner of per-
forming the same, I would have it understood I do not confine myself
to the precise details herein described and represented in the accom-
panying Drawings, as these may obviously be modified without departing
from the principle upon which the improvements are based; but what I
claim and desire to secure by the said Letters Patent is, the toothed plate
or part clipping the hairs operating with a circular motion in machines

described and shewn in the Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this Eleventh day of November,
in the year of our Lord One thousand eight hundred and sixty-
ninc.
