City of London, Patent Agent and Consulting Engineer, for the Invention
of "IMPROVEMENTS IN APPARATUS FOR CLIPPING HORSES OR OTHER ANIMALS."

PROVISIONAL SPECIFICATION left by the said John Clayton Mewburn at
the Office of the Commissioners of Patents on the 4th June 1877.
JOHN CLAYTON MEWBURN, of 169, Fleet Street, in the City of London, Patent
Agent and Consulting Engineer. "IMPROVEMENTS IN APPARATUS FOR CLIPPING
HORSES OR OTHER ANIMALS." [A communication from abroad by Augusto Lengelée,
of Paris, France.]
Hitherto apparatus for clipping horses or other animals commonly called "horse
clippers" have been constructed so that the joint of the movable handle to the
fixed handle is formed by a screw, stud, or pin, which constitutes the axis on which
the apparatus works.
Now, an essential feature of the improved clipper, which forms the subject of the
present Invention is, that it works without a pin, screw, or stud, a circumferential
friction being obtained, as herein-after described.
Another feature is the employment of screws and nuts, as herein-after described,
to tighten the two cutters by the plate superposed on the movable cutter.
The improvements will be fully understood by the following description of a
clipper constructed according to this Invention:-To the fixed cutter is screwed a
T shaped piece, the vertical limb of which forms the shank of the fixed handle.
The head of the T shaped piece has a circular opening on its under side to receive
a disc near the end of the shank of the movable handle. It is this disc, in com-
bination with the circular opening in the T shaped piece, which constitutes the
working or axial point with circumferential friction of the apparatus. The end of
the shank of the inovable handle is rounded, and actuates the movable cutter by
making it slide between the fixed culter and the plate of the clipper. This plate
serves to tighten the cutters against each other by means of screws; the heads of

page_text: these screws take into countersinks in the fixed cutter, their stems pass through
holes in the movable cutter and screw into the plate, being prevented from working
loose by nuts screwed on to their ends. By turning the screws more or less the
cutters can be tightened, as required.
The screws also serve as guides to the movable cutter in its movement on the
fixed cutter, the holes in the inovable cutter through which the screws pass being
elongated for the purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Clayton Mewburn in the Great Seal Patent Office on the 17th
November 1877.
JOHN CLAYTON MEWBURN, of 169, Fleet Street, in the City of London, Patent
Agent and Consulting Engineer. "IMPROVEMENTS IN APPARATUS FOR CLIPPING
HORSES OR OTHER ANIMALS." (A communication from abroad by Auguste Lengolée,
of Paris, France.)
Hitherto, apparatus for clipping horses or other animals have been constructed so
that the joint of the movable handle to the fixed handle is formed by a screw,
stud, or pin, which constitutes the axis on which the apparatus works.
Now, the essential feature of the improved clipper which forms the subject of the
present Invention is, that it works without a pin, screw, or stud, a circumferential
friction being obtained, as herein-after described.
Another feature is the employment of screws and nuts, as herein-after described,
to tighten the two cutters by the plate superposed on the movable cutter.
Figure 1 of the annexed Drawings is an elevation of a clipper constructed
according to this Invention, and suitable for clipping horses. Figure 2 is a trans-
verse section; and Figure 3, a horizontal section of the same.
To the fixed cutter a is screwed a T shaped piece b, the vertical limb g of which
forms the shank of the fixed handle. The piece 6 has a circular opening on its under
side to receive a disc d on the shank c¹ of the movable handle. This shank with its
disc is shewn separately in Figure 4. It is this disc, in combination with the
circular opening in the piece b, which constitutes the working or axial point with
circumferential friction of the apparatus. The end of the shank c¹ is rounded,
and actuates the movable cutter a, by making it slide between the fixed cutter u
and the plate g. This plate-serves to tighten the cutters against each other by
means of screws-v-the-heads.of.these screws take into countersinks in the fixed
cutter u, their stems pass through holes in the movable cutter and screw into the
...plate.g,.being_prevented from working loose by nuts h screwed on to their ends.
By-turning the screws more or less, the-cutters can be tightened as required.
The screws also-serve-as guides to the movable-cutter in its movement on the
fixed cutter, the holes i in the movable cutter through which the screws pass being
elongated for the purpose.
Figure 5 is an elevation of the clipper, arranged to act as a trimming cutter,
Figure 6 being a transverse section, and Figure 7 a horizontal section.
To the fixed cutter a is screwed the handle c. The inovable cutter a¹ moves
between the cutter a and the upper plate g, which is connected to the fixed cutter
by two screws v; the cutter a has clongated holes i which allow of its movement.

page_text: The handle c' is formed with a disc d (seen in the detached view, Figure 8), which
is engaged in a circular cavity in the handle c; the end of the handle works the
movable cutter a'. The handles c, c, are kept apart by the spring r screwed to the
handle c at e, and bearing against the piece h, which is free to turn on the axis o on
the handle c. The spring has thus no friction on the handle c, the action is very
easy, and the clipper is readily worked with one hand.
Figure 9 is an elevation of the cutters of an apparatus adapted for shearing
sheep. The only difference is in the form of the teeth, which are longer and
wider.
In this apparatus and in that shewn in Figure 5 the nuts of the screws are not
represented, as they may be dispensed with.
And having now described the nature of the said Invention and in what manner
the same is to be performed, I declare that I claim constructing apparatus for
clipping horses or other animals, with the joint of the movable and fixed handles
made without a screw, stud, or pin, and with circumferential friction, substantially
as herein-before described and represented in the annexed Drawings.
In witness whereof, I, the said John Clayton Mewburn, have hereunto set
my hand and scal, this Fifteenth day of November, One thousand eight
hundred and seventy-seven.
