I JOSEPH TRICKETT of Newark upon Trent, in the County of Nottingham,
Cutler, do hereby declare the nature of my Invention for IMPROVEMENTS IN
APPARATUS FOR CLIPPING HORSES, SHEARING SHEEP, AND OTHER ANALOGOUS
PURPOSES, to be as follows: —
The object of my invention is to manufacture an improved form and arrangement
of apparatus for clipping horses, shearing sheep, and other analogous purposes.
I construct my improved clippers in the form of levers of the third order, in
which the power is exerted between the fulcrum and the work; and, whether
operated by the alternate opening and closing of the hand, or by spur gear, as
hereinafter described, the position of the hand or of the spur gear (as the case may
be) is between the fulcrum and the cutting plates.
With the exception of the position of the fulcrum, the cutting plates may, in
some cases, be fitted and arranged as described in my Specification N° 2910".
In other cases I construct the bottom cutting plate of a thickness suitable to the
required length of hair; and I provide a number of such cutting plates of various
thicknesses, any one of which may be readily attached thereto or removed
therefrom, by means of a screw and fly-nut; whereby the hair may be cut to the
desired length with certainty and precision.
In arranging the apparatus for working with one hand only, I provide a guard
to one of the levers or handles for accommodating the fingers, and another guard
to the other handle for accommodating the thumb, whereby the apparatus is
securely held in the hand. A spiral or other spring or springs is or are fitted to
the handles or levers, whereby they are pressed outwards. By alternately.
expanding and contracting the hand the reciprocating motions of the levers and
cutting plates are effected.
Instead of operating the cutting plates by the hand, as last described, I sometimes
fit an eccentric to the levers, between the fulcrum and the cutting plates; this
eccentric is centred in one lever, and works in a guide or slot in the other lever,
and is driven by spur or other speed gear, whereby a rapid rotation of the eccentric
takes place, and a rapid reciprocating motion is imparted to the cutting plates.
A suitable handle is fitted whereby the apparatus is firmly held in one hand, while
the other hand is used in operating the driving gear.

Sheep, and other Analogous Purposes.
I JOSEPH TRICKETT, of Newark upon Trent, in the County of Nottingham,
Cutler, do hereby declare the nature of my said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention is to manufacture an improved form and arrangement
of apparatus for clipping horses, shearing sheep, and other analogous purposes.
I construct my improved clippers in the form of levers of the third order, in
which the power is exerted between the fulcrum and the work; and, whether
operated by the alternate opening and closing of the hand, or by spur gear, as
hereinafter described, the position of the hand or of the spur gear (as the case may
be) is between the fulcrum and the cutting plates.
With the exception of the position of the fulcrum, the cutting plates may, in
some cases, be fitted and arranged as described in my Specification No 291081.
In other cases I construct the bottom cutting plate of a thickness suitable to the
required length of air; and I provide a number of such cutting plates of various
thicknesses, any one of which may be readily attached thereto or removed therefrom,
by means of a screw and flynut; whereby the hair may be cut to the desired length
with certainty and precision.
In arranging the apparatus for working with one hand only, I provide a guard to
one of the levers or handles for accommodating the fingers, and another guard to
the other handle for accommodating the thumb, whereby the apparatus is securely
held in the hand. A spiral or other spring or springs is or are fitted to the handles
or levers, whereby they are pressed outwarda. By alternately expanding and
contracting the hand the reciprocating motions of the levers and cutting plates are
. effected.
Instead of operating the cutting plates by the hand, as last described, I some-
times fit an eccentric to the levers, between the fulcrum and the cutting plates;
this eccentric is centred in one lever, and works in a guide or slot in the other lever,
and is driven by spur or other speed gear whereby a rapid rotation of the eccentric
takes place, and a rapid reciprocating motion is imparted to the cutting plates.
A suitable handle is fitted whereby the apparatus is firmly held in one hand, while
the other hand is used in operating the driving gear.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1. is an elevation, shewing the invention as constructed for working with one
hand only. a a are the cutting blades; 6 6¹ are the two levers, the lever 61 being
attached to the front plate 6 and the lever b actuating the moveable cutting
plate b. The levers are pivotted at c. d is the space for the thumb, and a the
space for the fingers. f is a spiral spring which presses the levers apart; the spring

page_text: is retained in position by the two fixed pins g g. Other forms of springs may be
fitted for effecting the same purpose.
Fig. 2 is a back view of another arrangement of my invention as fitted with speed
gear, and Fig. 3 is a front view of the same. h is a spur wheel mounted upon a
pin in the fixed lever b¹ and fitted with the handle i
This wheel drives the pinion k which pinion is also fitted to the fixed lever b¹.
The pinion k drives the eccentric l, which works in the slot in the vibrating
lever b. m is a handle, by which the apparatus is held in one hand, while with
the other hand, the handle i is turned. Bevel gear may be substituted for
that shewn.
Fig. 4 is a side view of the upper portion of Fig. 1; the arrangements for
adjusting the plates to the required length of hair being similar to that described in
my said former Specification Nº 2910¹.
I sometimes arrange my invention so that the length of the hair may be governed
by the thickness of the back plate 6; and for that purpose I provide change plates
of various thicknesses, which may be removed and exchanged by merely unscrewing
the flynut n. One form of these adjusting plates is shewn in fig. 5 (in perspective)
and side views of other forms and thicknesses are shown in Figa. 6. 7 and 8, by
the use of which the hair may be cut to any desired length.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The manufacture and use of apparatus for the purposes aforesaid having the
fulcrum c arranged at the outer ends of the levers, substantially as herein before
described and shewn in Figs. 1. 2 and 3 of the drawings.
2. The manufacture and use of apparatus as aforesaid, provided with springs
for pressing the levers b b¹ outwards, substantially as herein before described.
3. The manufacture and use of apparatus as aforesaid, fitted with speed
gear hk, or analogous gearing, and eccentric l, driving the lever b substantially as
hereinbefore described, and shewn in Figs. 2 and 3 of the Drawings.
4. The manufacture and use of adjustable plates 6 for regulating the length of
hair, substantially as herein before described and shewn in Figs. 5. 6. 7 and 8 of the
Drawings.
5. The general construction, arrangement and combination of the several and
respective parts, or of some of them, constituting my improvements in apparatus
for clipping horses, shearing sheep, and other analogous purposes, substantially as
hereinbefore described and shewn on the Drawings.
