IMPROVEMENTS IN CLIPPERS FOR HAIR AND OTHER PURPOSES
Year: 1881

page_text: LETTERS PATENT to Joseph Trickett, of Newark upon Trent, in the County
of Nottingham, Cutler, for an Invention of "IMPROVEMENTS IN CLIPPERS
FOR HAIR AND OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said Joseph Trickett at the Office
of the Commissioners of Patents on the 4th July 1881.

My improvements consist in a metal cover plate to which is rigidly attached a
handle; the underside of this cover plate carries four studs, which take into holes
formed for them in the bottom fixed cutter, two being in the front & two in the
rear. These studs act as distance pieces between the cover plate and the bottom
cover; between them is the movable reciprocating cutter provided with slots
through which the front studs pass and act as guides. The cover plate and the
bottom fixed cutter are securely held together by a central bolt which passes
through them both as well as the movable cutter, which has a slot formed in it for
that purpose. Spring washers can be placed on the studs or distance pieces to give.
a certain amount of elasticity between the cover plate and to the bottom fixed
cutter, and allow the movable cutter to slide freely between them. Motion is given
to the movable cutter by a lever pivotted to the underside of the fixed handle, and
provided with a cam shaped head taking into a recess formed for it in the movable
cutter, so communicating the motion of the hand through the lever to the cutter.
In cases where only one hand can be employed to work the clipper, as in sheep
shearing, I place a spring between the fixed handle and the movable lever to keep
them constantly open when not pressed together by the hand. To regulate the
length of hair or wool cut by the clipper I employ a comb underneath and parallel
to the bottom fixed cutter; the distance between them, and consequently the
length cut, is adjusted by long screws or other mechanical arrangement fixed to but
capable of revolving in the comb. A cross bar is attached to the clipper by the
central bolt, and has at its ends screwed holes, which receive the end of the long
screws of the comb, so that by turning them round they screw in or out of the cross
bar and thus regulate the distance between the comb and the bottom fixed cutter
at pleasure.

the said Joseph Trickett in the Great Seal Patent Office on the 4th January
1882.

Figure 1 represents a plan of the upper side of my improved clippers; Figure 2
is a section of the same on the line X, X; and Figure 3 is a plan of the under side
of the same with the lower cutter plate removed. The metal cover plate A has
the handle A cast with it in one piece or otherwise rigidly fastened to it; the
under side of this cover plate carries four studs, two of them a, a, being in the
front and two a', a', being in the rear. These studs act as distance pieces between
the cover plate A and the lower fixed cutter plate B, and enter into holes made in
the cutter plate B for that purpose; between the cover plate A and the lower
cutter plate B is the moveable reciprocating cutter plate C provided with slots c, c,
through which the front studs a, a, pass and form guides. A central bolt D. passes
through the lower cutter plate B and the cover plate A and securely holds them
together. Springs, as shewn at a and a¹ in Figure 5, may be placed on the studs
between the cover plate A and the upper and lower cutter plates C and B, so as to
allow a certain amount of elasticity between them.

Motion is given to the reciprocating cutter plate C by a lever handle E
voted at e to the under side of the fixed handle A¹, and provided with a cam
shaped head F, which takes into a recess formed for it in the reciprocating cutter
plate C, as clearly shown in Figure 3. A slot d is formed in the cam head F to
allow it to reciprocate on either side of the central bolt D and so cominunicate any
motion given by hand through the lever handle E to the reciprocating cutter
plate C.
By taking out the central bolt D the lower cutter plate B and the upper one C
can be at once detached and removed separately from the body of the clipper
for sharpening or renewal without disturbing any other part of the operating
mechanism.
Figure 4 represents a plan of the under side of a clipper, constructed as above
described, but provided with handles A and E for use with one hand only.
Springs G and G' are inserted between the handles to keep them constantly open
when not pressed together by the hand. A simple spring, as shewn at G in
Figure 6, inay be employed in lieu of the double springs, or a simple spiral spring
may be used for the same purpose.
To regulate the length of hair or wool to be cut by the clipper I employ a
comb H underneath and parallel to the lower cutter plate B, as shewn in Figures 5
and 6; in Figure 6, for clearness, the cutter plates B and C are not shown in
detail, but their outline is shown by a dotted line. The distance between the
comb H and the cutter plate B, and consequently the length of hair or wool to be
cut, is regulated by two long screws J and J' fixed to but capable of revolving in
the comb H, as shown partially in section in Figure 5; a cross bar K. is attached
to the cover plate A by the central bolt D and has at its ends screwed holes to
receive the long screws J and J, so that by turning them round they screw in or
out of the cross bar K, and carrying the comb H with them regulate its distance
from the cutter plate B.
Figures 7 and 8 show a modification of the means of regulating the comb H;
in lieu of the two long screws the sides of the comb are turned or carried up to
form the long slots J and J, and by which the comb H can be clamped at any
required distance from the cutter plate B, with the clamping screws j and j',

page_text: projections are made on the cover plate A, both to receive the screws j and j¹, and
also to form guides for the long slots J and J¹.
Having now described my Invention, and in what manner the same is to be
carried into effect, what I claim is,-
First. The arrangement of parts constituting my improved clipper, in com-
bination with the central bolt D and the lever handle E pivoted to the cover
plate A, substantially as shown and described, or any mere modification thereof.
Secondly. The application of the comb H to clippers for regulating the length
to be cut, substantially as shewn and described, or any mere modification
thereof.
In witness whereof, I, the said Joseph Trickett, have hereunto set my hand
and seal, this Twenty ninth day of December, in the year of our Lord
1881.
JOSEPH TRICKETT. (L.S.)
