Year: 1865

page_text: LETTERS PATENT to William Singleton, of Sheffield, in the County of
York, Cutlery Manager, for the Invention of "IMPROVEMENTS IN APPA-
RATUS FOR CUTTING SCALES FOR KNIVES, AND FORMING METAL WEBS FOR
KNIVES."
Sealed the 30th January 1866, and dated the 1st August 1865.
PROVISIONAL SPECIFICATION left by the said William Singleton at the
Office of the Commissioners of Patents, with his Petition, on the 1st
August 1865.
WILLIAM SINGLETON, of Sheffield, in the County of York, Cutlery
Manager, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR CUTTING SCALES FOR KNIVES, AND FORMING METAL WEBS
FOR KNIVES," to be as follows:-
The apparatus for cutting scales for knives consists of a table, across which
for about two-thirds of its breadth there is a slot or saw gate, and a portion
of the table from the saw gate to the end farthest from it is removed to allow
of the insertion of a frame carrying the scale to be cut; the table carries
clamping screws to hold the scale firmly in its place The table is held upon
axes, and is maintained in a horizontal position by a spring or springs. Under
the table and in a line with the saw gate is a circular saw. After the scale is
in position the pressure of the spring is overcome, and the table is inclined

page_text: downwards to cause the saw to enter the saw gate and cut off that portion of
the scale extending beyond it.
The apparatus for forming metal webs for knives consists of a steel matrix
of the shape of the intended web and pierced with holes, and of a punch
carrying pins corresponding with the shape of the matrix and with the holes
drilled in it By working the punch in a hand or steam press the thin metal
web is formed and pierced with the necessary holes at one operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Singleton in the Great Seal l'atent Office on the
1st February 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SINGLETON, of Sheffield, in the County of York, Cutlery Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Singleton, Her special licence that I, the said William
Singleton, my executors, administrators, and assigns, or such others as I,
the said William Singleton, my 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 APPARATUS FOR CUTTING SCALES FOR KNIVES, AND FORMING
METAL WEBS FOR KNIVES," upon the condition (amongst others) that I, the
said William Singleton, my executors or administrators, by an instrument in
writing under my, 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 1, the said William Singleton, 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

page_text: statement thereof, reference being had to the Drawings hereunto annexed,
that is to say-
The apparatus for cutting scales consists of a table, across which for about
two-thirds of its breadth there is a slot or saw gate, and a portion of the table
from the saw gate to the end farthest from it is removed to allow of the
insertion of a frame carrying the scale to be cut; the table carries clamping
screws to hold the scale firmly in its place. The table is held upon axes, and
is maintained in a horizontal position by a spring or springs. Under the table
and in a line with the saw gate is a circular saw. After the scale is in
position, the pressure of the spring is overcome and the table is inclined
downwards to cause the saw to enter the saw gate and cut off that portion of
the scale extending beyond it.
Figure 1 of the accompanying Drawings is a side elevation; Figure 2 an
end elevation, and Figure 3 a plan of an apparatus constructed according to
this part of my Invention for cutting scales. A, A, are standards formed with
bearings, in which tightening screws B, B, are fitted; the inner ends C, C, of
the screws form axes upon which the table D is held; E is a slot or saw gate
cut across the table for about two-thirds of its length. A portion of the table
from F to F is removed to allow of the insertion of a frame G carrying the
scale to be cut. I prefer that the portion of the table thus removed should
leave a dovetailed recess in the table as represented in Figure 4, which
is an end view of the table; II, H, are clamping screws to hold the frame G
firmly in its place; I is a spring to maintain the table D in a horizontal
position; J is a circular saw in a line with the saw gate E. This saw is
carried on a shaft K, working on axes L, L, forming the inner ends of
tightening screws M, M, which are fitted in bearings in standards N, N. O is
a pulley by which motion is transmitted to the shaft K by a belt. After the
scale is in position the pressure of the spring I is overcome, and the table D
is inclined downwards, as shewn by the dotted lines in Figure 2, to cause the
saw J to enter the saw gate and cut off that portion of the scale extending
beyond it.
The apparatus for forming metal webs for knives consists of a steel matrix
of the shape of the intended web, and pierced with holes, and of a punch
carrying pins corresponding with the shape of the matrix, and with the holes
drilled in it.
Figure 5 is a perspective view of this apparatus. A is a steel matrix carried
on a bed B, and of the shape of the intended web; it is pierced with holes
as shown; C is a punch, of corresponding shape, and carrying pins coire-

page_text: sponding to the holes in the matrix A. By working this punch in a hand or
steam press the thin metal web is formed and pierced with the necessary
holes at one operation.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, constructing apparatus for cutting scales for knives, arranged and
acting substantially as herein-before described and represented in Figures 1 to
4 of the accompanying Drawings.
Second, constructing apparatus for forming metal webs for knives, arranged
and acting substantially as herein-before described and represented in Figure 5
of the accompanying Drawings.
In witness whereof, I, the said William Singleton, have hereunto set my
hand and seal, this Thirty-first day of January, One thousand eight
hundred and sixty-six.
