Year: 1871

page_text: LETTERS PATENT to Paul Nestor Priqueler, of Rue des Vinaigriers,
No. 55, à Paris, Engineer, for the Invention of "IMPROVED MACHINERY
FOR HEADING OR PUNCHING PINS, NAILS, RIVETS, SCREWS, AND OTHER SIMILAB
ARTICLES."
Sealed the 6th February 1872, and dated the 28th August 1871.
PROVISIONAL SPECIFICATION left by the said Paul Nestor Priqueler
at the Office of the Commissioners of Patents, with his Petition,
on the 28th August 1871.
I, PAUL NESTOR PRIQUELEB, of Rue des Vinaigriers, No. 55, à
Paris, Engineer, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY FOR HEADING OR PUNCHING PINS, NAILS, RIVETS,
SCREWS, AND OTHER SIMILAR ARTICLES," to be as follows:-
With the several arrangements of machines which have heretofore
been employed for heading or punching pins, rivets, and other similar
articles, rapidity and perfection of manufacture have not both been
obtained. Now with my improved machinery I not only obtain per-
fection in the stamping or punching, but I am also able to carry on the
operation with rapidity.

page_text: My machine is of continuous action and its distinguishing features
are the regularity of the stamping, the automatic introduction to the
stamping matrices or punches, and the mechanism for driving out the
stamped rivets or other articles. The machine consists of a rigid frame,
at the upper part of which is a horizontal shaft having a cranked arm
which imparts up-and-down movement to a punch or matrix carrier.
This shaft carries a toothed wheel which receives motion from a pinion
on the main shaft, and it transmits this motion by toothed gearing to
two parallel horizontal shafts, each of which carries a cam. These cams
act against two rollers at the two ends of a sliding rivet holder in order
to give this holder successively and at proper times a rectilinear move-
ment in one direction and then a suitable rest, and then a rectilnear
movement in the opposite direction, which movements and rest correspond
with the following operations, viz.; the introduction of the rivets to be
stamped below the punches, the stamping of the heads of these rivets,
and the driving out of these stamped rivets at the same time as the
introduction of fresh rivets to be stamped. The rotary motion is further
transmitted by toothed gearing from the shafts which carry these cams
to two other horizontal shafts which carry cams to actuate the mechan-
ism for driving out the stamped rivets. This mechanism consists of two
vertical pushers which are connected by a tie or stay provided with a
double roller which receives motion directly from the cams. Abutments
prevent the pushers falling too low in their downward movement.
The punch carrier, the cams which move the rivet holder, and the
cams which actuate the driving out mechanism being thus all worked
simultaneously from the main shaft the action of the machine is as
follows: Two or more rivets are fed by hand or otherwise to apertures
in the rivet holder, the punch carrier descends to stamp the heads of
these rivets, the rivet holder moves in one direction so that the stamped
rivets are clear of the punches and directly over the driving out
mechanism, the stamped rivets are then driven out at the same time.
as two or more other rivets which have been fed to other apertures in
the holder are being stamped, the rivet holder then moves in the opposite
direction, and so on. There is thus continuity in the production, it being
simply necessary for the attendant to place the rivets to be stamped
in the empty apertures of the holder as fast as on one side and the
other the driving out mechanism discharges the stamped rivets.

filed by the said Paul Nestor Priqueler in the Great Seal Patent
Office on the 8th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
NESTOR PRIQUELER, of Rue des Vinaigriers, No. 55, à Paris, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Paul Nestor Priqueler, Her
special licence that I, the said Paul Nestor Priqueler, my executors,
administrators, and assigns, or such others as I, the said Paul Nestor
Priqueler, 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
"IMPROVED MACHINERY FOR HEADING OR PUNCHING PINS, NAILS, RIVETS, SCREWS,
AND OTHER SIMILAR ARTICLES," upon the condition (amongst others) that
I, the said Paul Nestor Priqueler, 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 Paul Nestor Priqueler 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 statement thereof, reference being had to the accom-
panying Drawings, that is to say :-
With the several arrangements of machines which have heretofore
been employed for heading or punching pins, rivets, and other similar
articles, rapidity and perfection of manufacture have not both been
obtained. Now with my improved machinery I not only obtain per-
fection in the stamping or punching, but I am also able to carry on
the operation with rapidity.

page_text: My machine is of continuous action and its distinguishing features
are the regularity of the stamping, the automatic introduction to the
stamping matrices or punches, and the mechanism for driving out the
stamped rivets or other articles.
The Invention will be fully understood by the annexed Drawings,
which represent one of my improved machines.
Figure 1 is a front elevation and Figure 2 a side elevation of the
machine.
Figures 3, 4, and 5 are views of certain parts detached.
The machine here shewn consists of a rigid frame A, A, of such size
and form as will prevent injurious vibration and resist all strains and
shocks produced by the working of the machine. At the upper part B
of this frame is a horizontal shaft a (shewn separately in Figure 5)
having a cranked arm b, which imparts up-and-down movement to a
punch or matrix carrier c. This shaft carries a toothed wheel which
receives motion from a pinion d on the main shaft, and it transmits
this motion by toothed gearing g, h, h¹, to two parallel horizontal shafts
i, i¹, each of which carries a cam C. These cams C (one of which is
shewn separately and on a larger scale in Figure 3) act against two
rollers m, m³, at the two ends of a sliding rivet holder G in order to
give this holder successively and at proper times a rectilinear movement
in one direction, then a suitable rest, and then a rectilinear movement
in the opposite direction, which movements and rest correspond with
the following operations, viz., the introduction of the rivets to be
stamped below the punches, the stamping of the heads of these rivets,
and the driving out of the stamped rivets at the same time as the
introduction of fresh rivets to be stamped. The rotary motion is further
transmitted by toothed wheels j, j, mounted on the shafts i, i, to
two other wheels k, k³, of the same diameter on horizontal shafts 2, 1,
which carry cams D, D, (one of which is shewn separately in Figure 4)
to actuate the mechanism for driving out the stamped rivets. This
mechanism consists of two vertical pushers o, o, which are connected
by a tie or stay p provided with a double roller q which receives
motion directly from the cam D. Abutments 8, 8, prevent the pushers
falling too low in their downward movement. The punch carrier c,
the cams C which move the rivet holder G, and the cams D which
actuate the driving out mechanism being thus all worked simultaneously
from the main shaft, the action of the machine is as follows:-Two or

page_text: more rivets r, hot or cold, are fed by hand or otherwise to apertures
in the rivet holder G, the punch carrier c descends to stamp the heads
of these rivets, the rivet holder is moved in one direction by the action
of the cams O, O, the actions of which are complementary one to the.
other so that the stamped rivets are clear of the punches n, and directly.
over the driving out mechanism; the stamped rivets are then driven
out at the same time as two or more other rivets which have been fed
to other apertures in the holder are being stamped, the rivet holder
then moves in the opposite direction and so on. There is thus continuity
in the production, it being simply necessary for the attendant to place
the rivets to be stamped in the empty apertures of the holder as fast
as on one side and the other the driving out mechanism discharges the
stamped rivets.
The distinguishing features of my improved machinery are, first, the
perfection of the stamping resulting from the freedom of movement of
the punches with respect to the articles to be stamped; secondly, the
automatic introduction of such articles to the punches by means of the
cams C, O, the respective actions of which are reciprocally comple-
mentary; third, the mechanism for driving out the stamped articles by
means of the cams D, D, and pushers o, ọ; and, fourthly, the general
arrangement or. combination of parts of the machine by which rapid
and regular stamping is effected.".
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, con-
structing machinery for heading or punching pins, nails, rivets, screws,
and other similar articles, substantially as herein-before described and
represented in the annexed Drawings..
In witness whereof, I, the said Paul Nestor Priqueler, have here-
unto set my hand and seal, this Twenty-ninth day of January
One thousand eight hundred and seventy-two.
P. N. PRIQUELER. (L.S.).
