page_text: LETTERS PATENT to William Jones, of Birkenhead, in the County of
Chester, Boiler Maker, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR PUNCHING AND SHEARING PLATES OF METAL, WHICH IMPROVEMENTS ARE
ALSO APPLICABLE TO STAMPING AND PRESSING METALS AND OTHER SUBSTANCES.
ALSO APPLICABLE TO STAMPING AND PRESSING METALS AND OTHER SUBSTANCES.
Sealed the 11th December 1855, and dated the 16th June 1855.
PROVISIONAL SPECIFICATION left by the said William Jones at the
Office of the Commissioners of Patents, with his Petition, on the 16th
June 1855.
I, WILLIAM JONES, of Birkenhead, in the County of Chester, Boiler Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR PUNCHING AND SHEARING PLATES OF METAL, WHICH IMPROVEMENTS
ARE ALSO APPLICABLE TO STAMPING AND PRESSING METALS AND OTHER SUBSTANCES,"
to be as follows:-
I make the framing of the machine so wide as to contain as many punches
placed in a line as there may be holes required in the length of the plate., Over
these punches, instead of the ordinary lever or eccentric movement, usually
employed to depress and raise the punch, I use a roller the entire width of
the machine, which roller in section forms a tappet of a shape to accomplish
the same purpose, the eccentric parts of which run in a spiral direction, so that
this roller tappet acting on the heads of the punches spirally or in succession

page_text: as the roller revolves, there is never more power required than to punch out
one hole at a time, although it is repeated in such rapid succession that the
number punched in a given time is limited only by the speed the machine is
worked at. To alter the pitch or distance of the holes from each other, or
for curved lines, each punch and die has a separate guide, fixed by means of 5
bolts and regulating screws in slots across the machine, so that they may be
moved sideways or in any other required position.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Jones, in the Great Seal Patent Office on the
14th December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JONES, of Birkenhead, in the County of Chester, Boiler Maker, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Royal
Letters l'atent, bearing date the Sixteenth day of June, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself; Her heirs and successors, give and grant unto me, the
said William Jones, Her special licence that I, the said William Jones, my
executors, administrators, and assigns, or such others as I, the said William
Jones, 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 MACHINERY FOR
PUNCHING AND SHEARING PLATES OF METAL, WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO STAMPING AND PRESSING METALS AND OTHER SUBSTANCES," upon
the condition (amongst others) that I, the said William Jones, 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 Royal Letters Patent..
NOW KNOW YE, that I, the said William Jones, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-

page_text: My Invention consists of arranging or constructing the frame of the machine
or apparatus wide enough to contain as many punches placed in a line as there
may be holes required in the length of the plate. Over these punches, instead
of the ordinary lever or eccentric movement usually employed to depress and
raise the punch, I use a roller the entire width of the machine, which roller
in section forms a tappet of a shape to accomplish the same purpose, the
eccentric parts of which run in a spiral direction, so that this roller tappet
acting on the heads of the punches spirally or in succession as the roller
revolves, there is never more power required than to punch out one hole at a
time, although it is repeated-in such rapid succession that the number punched
in a given time is limited only by the speed the machine is worked at. To
alter the pitch or distance of the holes from each other, or for curved lines,
each punch and die has a separate guide, fixed by means of bolts and regu-
lating screws in slots across the machine, so that they may be moved sideways
or in any other required position.
The nature of my said improvements will be clearly understood by reference
to the accompanying two Sheets of Drawings, in which the same letters of
reference are used to represent the same parts in all the Figures.
Sheet 1 Fig. 1 is an elevation, and Fig. 2 a plan, of my punching
machine, some of the parts being shewn in section more clearly to define their
shape and action.
Sheet 2 Fig: 1 is an end view, and Fig. 2 is a plan, of one end of the
framing; also shewing the driving gear, by which motion is given and power
obtained to turn the tappet roller, which, acting upon the heads of the punches,
presses them in succession through the plate to be operated upon; and in
revolving afterwards acts upon the lever or counterweight, thus withdrawing
the punches from the plate. These parts are also shewn principally in section.
Figs. 3 and 4, No. 2 Sheet, shew the punch on a larger scale, with its head
or socket and the end of the lever or counterweight bearing upon it.
a, a, represent the driving pullies, cog wheels, and pinions as usually arranged
to obtain power, the wheel being keyed upon the shaft of the spiral tappet
roller; c, c, c, are the punches acting freely in a plate or cross bar, bored to
the pitch or distance the holes are required from each other. This plate
being attached to the frame by means of bolts, can be easily removed and
replaced by others of different pitches and size, as may be required for various
kinds of work. The dies d, d, are fitted into a cross bar. bored.to.receive-them,
of the same pitch, and in a line with the punches in the upper guide bar, or
they may be adjusted by means of bolts and regulating screws to any required
position. e represents a lever for bringing back the punches to the required

page_text: position; f is a guide bar, which may be changed for different kinds of work;
9 is the spiral tappet roller.
Having thus fully described the nature and particulars of my said Invention,
and the manner of carrying the same into practical effect, I desire it to be
distinctly understood that I do not confine myself to the exact details herein
set forth, as such may be varied or modified without departing from the principle
thereof; but I claim the application of a continuous spiral or tappet roller
acting progressively on any reasonable number of punches or dies in the same
machine.
In witness whereof, I,, the said William Jones, have hereunto set my
hand and seal, this Thirteenth day of December, One thousand eight
hundred and fifty-five.
Signed, sealed, and delivered by the within-
named William Jones, in the presence of
GEORGE SMITII,
Patent Agent,
Liverpool.
WILLIAM JONES. (L.S.)
