in the County of York, Table Knife Handle and Spring Knife Scale
Manufacturers, for the Invention of "IMPROVEMENTS IN THE MANU-
"
FACTURING OF CUTLERY HANDLES AND MACHINERY EMPLOYED THERELNT
PROVISIONAL SPECIFICATION left by the said Frederic Kahnt and John
Bunting, at the Office of the Commissioners of Patents, with their
Petition, on the 30th June 1866.
We, FREDERIC KAHNT and JOHN BUNTING, both of Sheffield, in the County
of York, Table Knife Handle and Spring Knife Scale Manufacturers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURING OF CUTLERY HANDLES AND MACHINERY EMPLOYED THEREIN," to
be as follows:-
This Invention consists in manufacturing cutlery handles by machinery
instead of by hand. The machinery consists of five parts, each part being
separate when worked by hand, and combined by means of driving bands,
pulleys, and straps when actuated by steam or other motive power.
Fig. 1 is an ordinary handle, and Figs. 2, 3, 4, and 5 are the machines for
making the same and other shaped handles; Fig 2 is the planing machine;

page_text: Fig. 8 is the moulding machine; Fig. 4 is the rounding machine; and Fig. 5
is the drilling machine. These machines are supported by suitable framework
fixed to benches, as shewn on Drawings. The material of which the handle is
to be made is first cut by the planing machine, Fig. 2, the material being
placed in a vice B, which is attached to the slide rest C. This rest is moved
by a coarse screw, the handle passing underneath the cutter D; three or four
handles may be planed at once, according to the size of the cutter.
The part E, shewn on Fig. 1, is shaped by the moulding machine Fig. 3.
After the handle has been planed it is placed in a vice F, Fig. 3; after being
made fast it passes underneath the cutters G. The cutters are in three parts
screwed together on the spindle with a nut; after one side of the handle is
shaped it is turned over and passed again under the cutters. The guides H
determine the shape the handle is to be made, one being on each side of the
slide rest, so as to allow the cutters G to rise and fall. The rise and fall of
the cutters are caused by two long arms I fixed about 9 inches apart by two
strong stays; the cutters G revolve between the ends of the arm on a steel
spindle, and which steel spindle revolves in two-steel-centres; the arms are
balanced down on the guides by the weight J; the object of the weight is to
keep the cutters in work. The part K in Fig. 1 is shaped by the rounding
machine Fig. 4. After the handle leaves Fig. 3 it is placed in a chuck L
one end of which is fastened on the slide rest M by means of two circular
pins; these pins are placed so as to allow the chuck to revolve. The handle
end of the chuck is made with a screw, so as to lengthen or shorten the
handle as required; the object of the slide rest M is to press the handle on to
the cutter N and withdraw it from the said cutter. The part O in Fig. 1 is
turned 'by an ordinary oval machine; the part P, Fig. 1, is bored by the
boring machine, Fig. 5. The handle is fixed in the vice Q, which works with
the racks R, and which together actuates the drill S. Any shaped handle
can be formed by these machines, and any material can be employed.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent, s
and of an Order of the Lord Chancellor, by the said Frederic Kahnt
and John Bunting in the Great Seal Patent Office on the 14th January
1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERIC
KAHNT and JOHN BUNTING, both of Sheffield, in the County of York, Table 3
Knife Handle and Spring Knife Scale Manufacturers, send greeting.

Patent, bearing date the Thirtieth day of June, in the year of our Lord One
thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her beirs and successors, give and grant unto us, the said
Frederic Kahnt and John Bunting, Her special licence that we, the said
Frederic Kahnt and John Bunting, our executors, administrators, and assigns,
or such others as we, the said Frederic Kahnt and John Bunting, our
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURING
OF CUTLERY HANDLES AND MACHINERY EMPLOYED THEREIN," upon the condition
(amongst others) that we, the said Frederic Kahnt and John Bunting,
our executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said Frederic Kahnt and John Bunting,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This Invention consists in manufacturing cutlery handles by machinery
instead of by hand. The machinery consists of four parts, each part being
separate when worked by hand, and combined by means of driving bands,
pullies, and straps, when actuated by steam or other motive power.
Fig. 1 is an ordinary handle, and Figs. 2, 3, 4, and 5, are the machines
for making the same and other shaped handles; Fig. 2 is the planing machine;
Fig. 3 is the moulding machine; Fig. 4 is the rounding machine; and Fig. 5
is the drilling machine. The material of which the handle is to be made is
first cut by the planing machine Fig. 2, the material being placed in a vice B,
which is attached to the slide rest C. This rest is moved by a coarse screw,
the handle passing underneath the cutter D; three or four ban.lles may be
planed at once, according to the size of the cutter.
The part E, shewn on Fig. 1, is shaped by the moulding machine, Fig. 3.
After the handle has been plaued it is placed in a vice F, Fig. 3; after being
made fast it passes underneath the cutters G. The cutters are in three parts
"

page_text: screwed together on the spindle with a nutt; after one side of the handle is
shaped it is turned over and passed again under the cutters; the guides H
determine the shape the handle is to be made, one being on each side of the
slide rest, so as to allow the cutters G to rise and fall. The rise and fall of
the cutters are caused by two long arms I, fixed about 9 inches apart by two
strong stays; the cutters G revolve between the ends of the arm on a steel
spindle, and which steel spindle revolves in two steel centres; the arms I are
balanced down on the guides by the weight J; the object of the weight is to
keep the cutters in work. The part K in Fig. 1 is shaped by the rounding
machine Fig. 4. After the handle leaves Fig. 3 it is placed in a chuck L,
one end of which is fastened on the rest M by means of two circular pins;
the pins are placed so as to allow the chuck to revolve. The bandle end of
the chuck is made with a screw, so as to lengthen or shorten the handle as
required. The object of the slide rest M is to press the handle on to the
cutter N, and withdraw it from the said cutter. The part O in Fig. 1, is
turned by an ordinary oval machine; the part P, Fig. 1, is bored by the
boring machine Fig. 5. The handle is fixed in the vice Q, which works with
the racks R, and which together actuates the drill S. The drill S is fixed
into cutter T, which makes the end U a true surface; this is done the same
time as boring. Any shaped handle can be formed by these machines, and
any material can be employed.
Having now described the nature and object of our said Invention, and the
manner in which the same is or may be carried into practical effect, we would
observe in conclusion that we do not confine ourselves to the precise or exact
details herein-before given; but what we claim and desire to be secured by
the herein-before in part recited Letters Patent is, the improvements in the
manufacturing of cutlery handles, and in the machinery employed therein,
substantially as herein-before described, and more particularly as illustrated
on the Drawings annexed hereto, or any mere modification thereof.
In witness whereof, we, the said Frederic Kahnt and John Bunting,
have boreunto set our hands and seals, this Twenty-seventh day of
December, in the year of our Lord One thousand eight hundred and
