AN IMPROVED MACHINE FOR CUTTING METAL RODS AND BARS
Year: 1854

page_text: LETTERS PATENT to Andrew Peddie How, of Mark Lane, in the City
of London, Engineer, for the Invention of "AN IMPROVED MACHINE FOR
CUTTING METAL RODS AND BARS."--A communication from John Gallagher,
of New York, Engineer.
Sealed the 24th April 1855, and dated the 7th November 1854.
PROVISIONAL SPECIFICATION left by the said Andrew Peddie How at
the Office of the Commissioners of Patents, with his Petition, on the
7th November 1854.
I, ANDREW PEDDIE How, of Mark Lane, in the City of London, Engineer,
do hereby declare the nature of the said Invention for "AN IMPROVED MACHINE
FOR CUTTING METAL RODS AND BARS" (communicated to me by John Gallagher,
of New York, Engineer,) to be as follows:-
My machine consists of a bed plate and frame, with a circular orifice, in
which works a circular disc or plate, which disc is fitted excentrically with a
cutting tool. Upon the bed plate and frame is fixed a rest, with a sharp
edge, which comes immediately opposite to the cutting tool in the circular
disc. The disc is worked by a lever or other suitable means, and by hand
or other power. The action is as follows:-Suppose a length required to
be cut off a circular metal rod: the circular disc is moved, say, for instance,

page_text: by a lever, until the circular orifice in the cutting tool comes above or
opposite to the rest, which has a semicircular aperture for the rod to lie upon;
the lever is then brought down, and the rod will be severed between the cutter
and rest.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Andrew Peddie How in the Great Seal Patent Office
on the 7th May 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
PEDDIE HOW, of Mark Lane, in the City of London, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of November, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Andrew Peddie How, Her special licence, that I, the said Andrew
Peddie How, my executors, administrators, and assigns, or such others as
I, the said Andrew Peddie How, 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 "AN IMPROVED MACHINE FOR CUTTING METAL RODS AND BARS," (communi-
cated to me by John Gallagher, of New York, Engineer,) upon the condition
(amongst others) that I, the said Andrew Peddie How, by an instrument in
writing under my hand and seal, 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 Andrew Peddie How, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:―
My machine consists of a bed plate and frame with a circular orifice, in
which works a circular disc or plate, which disc is fixed excentrically with a

page_text: cutting tool. Upon the bed plate and frame is fixed a rest, with a sharp edge,
which comes immediately opposite to the cutting tool in the circular disc.
The disc is worked by a lever or other suitable means, and by hand or other
power. The action is as follows:-Suppose a length required to be cut off a
circular metal rod: the circular disc is moved, say, for instance, by a lever, until
the circular orifice in the cutting tool comes above, or opposite to the rest,
which has a semicircular aperture for the rod to lie upon; the lever is then
brought down, and the rod will be severed between the cutter and rest.
... Figure 1 of the Drawings hereunto annexed represents a side elevation,
and Figure 2 a vertical section, of a machine constructed according to this
Invention. E is a cast-iron bed plate, to which a rest F is fastened by studs ;
G is a sharp-edge or under 'die, which may be removed and replaced by
another larger or smaller, according to the size of the bolt, rod, spindle, &c.
to be cut; H is a journal in the bearing of the bed plate, in which a circular
die I is fitted. This die may also be removed and replaced by another suitable
for cutting larger or smaller rods. Both the dies G and I are placed excen-
trically to the axes of the journal. A is a sector, fixed upon the end of the
journal by the key k. This sector is cut with teeth upon its periphery, into
which gear the teeth of the pinion B, keyed upon the shaft L. The shaft L
turns in bearings in the upper part of the frame M, which is securely bolted
to the bed plate E. C is a handle fitted upon the end of the shaft L, by which
motion is communicated to the pinion, and through it to the sector A. The
manner of using this machine is as follows:-The bolt or rod to be cut is
introduced through the circular hole N (which runs through the journal H,
as well as through the die I), and protruded to the length required to be
cut off. Motion is given to the handle C in the direction of the arrow,
whereby the sector is brought down, and a length is cut off from the bolt
or rod; the handle C is then reversed, and the machine restored to its
former position, when the hole N is again brought up to receive the end of the
rod to-be cut.
Figure 3 is a side elevation, and Figure 4 a section, of a modification of
the plan for working the machine. It consists in adapting to the journal H
a lever D, which is depressed to sever the rod or bar. The other parts of the
machine are the same as described in Figures 1 and 2, and are marked with
similar letters of reference.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, the improved
machine for cutting metal rods and bars, in which the cutting is effected

page_text: by a cutter or die placed excentrically in a disc or plate, and brought-down
or caused to act against a fixed edge or die by hand or other power, in
the manner herein-before described; and represented in the Drawings hereunto
annexed.
In witness whereof, I, the said Andrew Peddie How, have hereunto
set my hand and seal, this Third day of May, One thousand eight
hundred and fifty-five.
