A NEW MACHINE OR APPARATUS FOR SHARPENING HORSE CLIPPERS, APPLICABLE ALSO TO OTHER SIMILAR PURPOSES
Year: 1877

page_text: LETTERS PATENT to Joseph Trickett, of Newark-upon-Trent, in the County of
Nottingham, Cutler, for the Invention of "A NEW MACHINE OR APPARATUS
FOR SHARPENING HORSE CLIPPERS, APPLICABLE ALSO TO OTHER SIMILAR
PURPOSES."
PROVISIONAL SPECIFICATION left by the said Joseph Trickett at the
Office of the Commissioners of Patents on the 5th September 1877.
JOSEPH TRICKETT, of Newark-upon-Trent, in the County of Nottingham, Cutler.
"A NEW MACHINE OR APPARATUS FOR SHARPENING HORSE CLIPPERS, APPLICABLE
ALSO TO OTHER SIMILAR PURPOSES."
This Invention consists of a new machine or apparatus for sharpening horse
clippers, and other similar purposes.
Hitherto horse clippers when blunt or out of order have to be sent away to be
repaired and sharpened, and which takes as a rule some three or four days, and in
the country having to be sent in most instances a distance of many miles.
My Invention consists in constructing a portable sharpening machine which will
obviate the necessity of sending horse clippers away to be sharpened.
The machine or apparatus for sharpening horse clippers, and which is applicable
for other and similar purposes, consists chiefly of a portable frame, horizontal,
vertical, or inclined, by preference vertical, and which can be fixed at pleasure in a
few seconds to any table or desk by means of an ordinary screw or lever cramp.
The said frame with its appendages can be constructed of one or several pieces
of metal, by preference malleable iron, and so arranged as to receive a large bevil
wheel or equivalent mechanism, which transmits motion by means of a handle
affixed to the said wheel or wheels attached to a spindle, which is by preference
vertical, and which carries at its extremities a block of stone or other sharp cutting
substance; by preference the said block is of wood, covered with emery compound,
and when required for sharpening horse clippers and other objects, to be slightly

page_text: convex, in order to grind away the object sharpened in a hollow form, which is of
great advantage in cutting machines, as it allows for their faces to be perfectly
flat.
This machine has also an anvil affixed or cast to it, which is very useful for
rivetting, setting teeth, and other purposes.
If necessary this Invention also includes a rest, or guide, or holder, so arranged to
the frame or machine as to secure great steadiness and precision to the object worked
upon.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Trickett in the Great Seal Patent Office on the 5th March
1878.

* A NEW MACHINE OR APPARATUS FOR SHARPENING HORSE CLIPPERS, APPLICABLE

This Invention consists of a new machine or apparatus for sharpening horse
clippers, and other similar purposes.
Hitherto horse clippers when blunt or out of order have to be sent away to be
repaired and sharpened, and which takes as a rule three or four days, and in the
country having to be sent in most instances a distance of many miles.
My Invention consists in constructing a portable sharpening machine which will
obviate the necessity of sending horse clippers away to be sharpened.
The machine or apparatus for sharpening horse clippers, and which is applicable
for other and similar purposes, consists chiefly of a portable frame, horizontal,
vertical, or inclined, by preference vertical, and which can be fixed at pleasure in a
few seconds to any table or desk by means of an ordinary screw or lever cramp.
The said frame with its appendages can be constructed of one or several pieces
of metal, by preference maleable iron, and so arranged as to receive a large bevil
wheel or equivalent mechanism, which transmits motion by means of a handle
affixed to the said wheel or wheels attached to a spindle, which is by preference
vertical, and which carries at its extremities a block of stone or other sharp cutting
substance; by preference, the said block is of wood, covered with emery compound,
and when required for sharpening horse clippers and other objects, to be slightly
convex, in order to grind away the object sharpened in a hollow form, which is of
great advantage in cutting machines, as it allows for their faces being brought
perfectly flat.
This machine has also an anvil affixed or cast to it, which is very useful for
rivetting, setting teeth, and other purposes.
If necessary this Invention also includes a rest, or guide, or holder, so arranged to
the frame or machine as to secure great steadiness and precision to the object worked
upon.
Such being the nature and object of my Invention, I will now proceed to describe
more in detail the manner in which the same is or may be performed or carried
into practical effect; and in order that the same may be distinctly understood, I
have annexed hereunto 1 Sheet of Drawings illustrative thereof, and have marked

page_text: the same with figures and letters of reference corresponding with those in the
following explanation thereof, that is to say,-
On the accompanying Drawings,-
Fig. 1 represents my improved vertical arrangements of machine for sharpening
or grinding horse clippers.
Fig. 2 is a modification of the same having the grinding block inverted.
And Fig. 3 is another modification arranged horizontally.
A is the portable frame of the machine, which can be readily attached or detached
from its support C by means of a clamping screw B; or a lever cramp can be used
for the same purpose. The part of the frame is constructed as an anvil block for
rivetting and other purposes. A bevel wheel and pinion D and D* are also carried
by the frame A, and are so arranged that on turning the handle E a quick rotation
is given to the grinding block F, which is attached to the spindle of the bevel
pinion D*.
The grinding block F can be made of stone or any other sharp cutting sub-
stance; but by preference I make it of wood covered with an emery compound, and
form its grinding surface slightly convex, in order to give a flat or rather hollow
surface to the article being ground. A rest or guide plate G is carried over the
grinding face of the block F by a forked carrier H, which is attached by a screw
or other suitable method to the frame A.
Fig. 4 shews a detached view of the rest or guide plate G, which has a slot
through it, diametrically crossing the grinding block F.
A holder K, also shewn detached in plan and elevation in Fig. 5, fits loosely into
the slot on the guide plate or rest, and has two projections or studs e, e, on its lower
end, which take into lioles made in the articles to be ground or sharpened, thereby
securely holding them from turning on the grinding block, and also enabling the
operator to put any desired pressure upon the article that is being ground or
sharpened.
In Fig. 1 the article to be ground or sharpened is represented in section at d, d,
which also shews the method in which it is held in position by the studs e, e, on the
holder K.
Fig. 6 represents a modification of the holder K and the rest or guide plate G, to
adapt them to the inverted arrangement of machine, shewn in Fig. 2, in this case,
as it would not be convenient to press upwards with the holder K on account of
the position of the handle E. I joint the holder K to a lever L, which is attached
to a fulcrum on the rest or guide plate G, so the lever need only be depressed to put
what pressure is required on the article that is being ground or sharpened.
Having now described my Invention and in what manner the same is to be
carried into effect, I would have it to be understood that what I claim and desire
to be secured to me by the herein-before in part recited Letters Patent is, the
construction and arrangement of machines or apparatus for sharpening horse clippers
and other similar purposes, substantially as herein-before described, and shewn on
Drawings, and for the purposes set forth, or any mere modification thereof.
In witness whereof, I, the said Joseph Trickett, have hereunto set my hand
and seal, this Fourth day of March, in the year of our Lord One thousand
eight hundred and seventy-eight.
