IMPROVEMENTS IN TOOLS FOR CUTTING SHIVES AND OTHER CONICAL BLOCKS
Year: 1861

page_text: LETTERS PATENT to William Price, of Lambeth, in the County of Surrey,
Carpenter, for the Invention of "IMPROVEMENTS IN TOOLS FOR CUTTING
SHIVES AND OTHER CONICAL BLOCKS."
Sealed the 17th January 1862, and dated the 20th July 1861.
PROVISIONAL SPECIFICATION left by the said William Price at the
Office of the Commissioners of Patents, with his Petition, on the 20th
July 1861.
I, WILLIAM PRICE, of Lambeth, in the County of Surrey, Carpenter, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN TOOLS
FOR CUTTING SHIVES AND OTHER CONICAL BLOCKS," to be as follows:-
My Invention consists in fixing upon and around a conical mandril or block
a conical band of steel, which is formed with saw teeth for cutting wooden
shives and other substances usually cut by saws, and with a knife edge for
cutting cork and other substances requiring a knife edge for cutting them.
The band does not extend round the whole circumference of the mandril, as
there is a space left between the ends thereof and the entering end is formed
with a knife edge. The cutter is adjustable on the mandril, and is made to
protrude more or less beyond the top or the base thereof, according to the
thickness of the shive or other article to be cut, and is retained in its position
by a ring driven over it and the mandril. The cutting is effected by rotary
motion being imparted to the tool.

by the said William Price in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
PRICE, of Lambeth, in the County of Surrey, Carpenter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Price, Her special licence that I, the said William
Price, my executors, administrators, and assigns, or such others as I, the
said William Price, 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 Inven-
tion for "IMPROVEMENTS IN TOOLS FOR CUTTING SHIVES AND OTHER CONICAL
BLOCKS," upon the condition (amongst others) that I, the said William
Price, 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 I, the said William Price, 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 fol-
lowing statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-,
My Invention consists in fixing upon and around a conical mandril or block
a conical band of steel, which is formed with saw teeth for cutting wooden
shives and other substances usually cut by saws, and with a knife edge for
cutting cork and other substances requiring a knife edge for cutting them.
The band does not extend round the whole circumference of the mandril, as
there is a space left between the ends thereof, and the entering end is formed
with a knife edge. The cutter is adjustable on the mandril, and is made to
protrude more or less beyond the top or the base thereof, according to the
thickness of the shive or other article to be cut, and is retained in its position

page_text: by a ring driven over it and the mandril. The cutting is effected by rotary
motion being imparted to the tool.
Figure 1 of the accompanying Drawings is a side elevation; Figure 2, a
longitudinal section; and Figure 3, a perspective view of this tool for cutting
shives and other conical blocks.
a is the conical mandril or block, to which the band of steel 6 is secured by
a metal ring c. The outer end of the band of steel is formed with saw teeth g,
as shewn, when wooden bungs are to be cut, and with a knife edge for cork
and other soft material. The mandril a carries a screw-threaded spindle d,
whereby it is connected to a lathe or other machine for communicating rotary
motion. f is a knife edge formed on the entering end of the steel band b.
The wood or other material to be cut is pressed towards and into the tool
while made to revolve. The shive or other conical block is pushed out by
inserting a rod in the aperture h, formed through the spindle d and mandril a.
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 as my improve-
ments in tools for cutting shives and other conical blocks, fixing upon and
around a conical mandril or block a conical band of steel, made to cut in
manner and for the purposes herein-before described. .
I
In witness whereof, I, the said William Price, have hereunto set my
hand and seal, this Twentieth day of January, One thousand eight
hundred and sixty-two.
WILLIAM PRICE. (L.S.)
