page_text: LETTERS PATENT to François Rigollot, of No. 15, Passage des Petites
Ecuries, Paris, in the Empire of France, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR MANUFACTURING RIVETING PEGS FOR
BOOTS AND SHOPS AND OTHER PINS OR PEAS "
Sealed the 3rd October 1862, and dated the 11th April 1862.
PROVISIONAL SPECIFICATION left by the said François Rigollot at the
Office of the Commissioners of Patents, with his Petition, on the 11th
April 1862.
I, FRANÇOIS RIGOLLOT, of No. 15, Passage des Petites Ecuries, Paris, in
the Empire of France, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MANUFACTURING RIVETING PEGS
POR BOOTS AND SHOES, AND OTHER PINS OR PEGS," to be as follows:―
My improved machine is composed, firstly, of a shaft carrying two eccentrics,
on which are placed two connecting rods, which move the knives of a shears.
Secondly, of a cam pulley keyed on the shaft. This pulley (which is entirely
novel) has a groove passing twice round it, and crossing. The crossing gives
a come-and-go motion to the slide block by means of a shuttle with steel
spindle fastened to the said slide block by a cast-iron piece. This pulley
(which plays an important part) has for main and essential object to render
the oblique motion of the carriages alternate, precise, and invariable, permitting
the pegs to be cut only when the carriages are absolutely stationary, by which

page_text: means pegs of a given number will always be of equal length. A regulator
placed at the side of the framing, aided by a rod, serves to diminish or increase
at will the oblique right and left motion of the carriages by means of a screw,
the framing acting as nut; a fly-wheel is keyed on the shaft. On the framing
are placed two metal plates, each carrying ten or more carriages fixed to it by
a spindle-forming pivot, and permitting said carriages to move obliquely. On
the framing is placed a connecting rod, which transmits- the oblique motion
from the right to the left side of the machine. Under the framing are three
pedestals or brackets, on which revolves the shaft, which receives its motion
from a motor by means of gearing beneath the machine, which gearing carries
a pulley in connection by a band with the cam pulley herein-before mentioned.
The bands (of sheet iron or other metal) being cut to a breadth regulated by
the number or denomination of peg required, they are placed in the carriages;
these bands are brought beneath the shears by means of two steel claws or
catches placed on each side within the carriage; these claws or catches receive
their come-and-go motion by means of two small levers also placed on each
side of the carriage. The carriages are formed to receive metal bands of five
or six different breadths, that is to say, with the same carriages pegs of five or
six different numbers or denominations may be manufactured.

fixed to the guide of the shears c by the small columns o". These cross-pieces
carry a screw.nl placed vertically on the axle of each carriage, the object of

page_text: which is to hold the fore part of the carriage on the slab. The Figure 26
represents an iron piece 2¹, on which are placed the small catches a" for the
rotation of the ratchet t by means of the screws 6", which act as their pivot.
These catches are pressed against the ratchets t by springs d", which are them-
selves fixed on the plate ¹ by screws e". The plate is fitted to the carriage
by a screw on a button or knob placed between the two ratchets t by a screw
forming spindle, placed in the hole f". In the slide g" is a stop v, which
causes the plate ¹ to pivot from the oblique movement of the carriages, so as
to produce the rotation of the ratchets placed behind the carriage with rotating
friction rollers. "The Figures 12 to 26 inclusive, as also 32 and 33, are drawn
half their usual size, all the other Figures are drawn to a scale of one-fifth.
The machine works as follows:-Motion is communicate to the shaft a by a
pulley keyed upon it. This shaft carries two eccentrics, on which are placed
The cam
the two connecting rods b, which move the knives of the shears c.
pulley d gives a. come-and-go motion to the slide block e, and this come-and-
go motion, by the aid of the rod f of the regulator g, gives to the carriages h
fixed at the back on the iron bands i the oblique motion right and left neces-
sary to the cutting of the pegs. The regulator g, placed on the frame j and
assisted by the rod f, serves to increase or lessen at will the oblique motion of
the carriages (according to the requirements of the denomination of peg being
made) by means of the screws k. On the shaft a is keyed the fly wheel l.
On each side of the frame j, and secured by four screws, are placed two
smooth cast-iron slabs m, on which are fixed the carriages h by a pin n
forming pivot, and permitting the oblique motion of the carriages. These
slabs are supported by four screws o, which permit their being lowered propor-
tionally to the decrease in width of the lower shears by the setting necessitated
by the work. On the frame j is also fixed the connecting rod p, which transmits
the oblique motion from the right to the left side of the machine. Beneath
the frame jare three pedestals 7, on which turns the shaft a.
Two arrange-
'ments of carriages may be applied indifferently to bring the bands or strips of
sheet metal beneath the shears. The first arrangement consists of four vertical
shafts, each surmounted by a toothed friction roller s (made of steel), which
serves to draw the sheet metal beneath the shears, and carrying a ratchet t for
its rotation. This rotary motion takes place, firstly, by the cone-and-go of
the carriage which causes the ratchet to describe a segment of a circle, and by
the double spring catches u fixed on the slab m by a screw v, as shewn,
Figures 21 and 22. The carriage carries in front two guide rods a, which close
or open at will, according to the width of the band of sheet metal, by means of
screws placed in the grooved holes formed in the guides. These guides are

page_text: intended to hold the bands of sheet metal when they escape from the carriage
on the lower shears, preserving the oblique motion to the end. The carriage
also carries in the entire length of the slide a third guidez, which prevents
the back sheet of metal from rising on to the foremost by leaving only sufficient
space between the guide and the bottom of the slide of the carriage for the
free passage of one band of sheet metal. Further on the sides of the carriage
are fixed by two screws, two double springs w, forming bearing to the vertical
shafts r, and pressing the friction rollers s against the sheet metal, to facilitate
its advance and avoid any interruption of the working if the said sheet of
metal should be of unequal breadth, and further permitting the placing in the
same carriage of several bands of sheet metal of different widths, that is to
say, the making of several denominations or numbers of peg with the same
carriage. The four screws a' are intended to uphold the two springs w when
the sheet of metal escapes from the friction rollers if it is not immediately
replaced by another, and to prevent the friction rollers coming against the
carriage. The two friction rollers s placed at the back of the carriage permit
a second band of metal to be placed in the slide of the carriage before the
first is entirely cut, the two front friction rollers holding its remains. The
second arrangement of carriage differs from the first, in that the advance of the
sheet metal beneath the shears instead of being effected by rotary friction
rollers is effected by two steel claws b', which receive a come-and-go motion,
producing the advance of the sheet metal by aid of the small levers c¹ placed
on each side of the said carriage. Each of these small levers carries a
tempered steel ring d', the object of which is to facilitate the motion of the
claw and avoid friction. These rings are placed at the point where the levers
act on the claws. Each claw presents a conical notch, in which work the
levers; this conical arrangement of the notches permits the claws to tighten
when the levers push them to advance the sheet of metal, and to open when
returning, so as not to draw back the sheet metal. The two levers c' placed
on each side of the carriage are fixed by two screws e', which serve them for
pivot on two steel springs f, also placed on each side the carriage. These
springs may open or close by means of the screws g³, according to the width
of the cross piece h², which ties together at the top the two levers c². The
width of the cross piece h¹ varies with the width of the band of sheet metal
which is to be placed in the carriage, for this carriage is so arranged as to
receive five or six different widths of these bands of sheet metal, that is to say;
that five or six different numbers of peg may be made with the same carriage. In
the middle of the cross piece, uniting the levers, is placed a small steel rod i',
which transmits motion to the lever. This motion takes place by means of

page_text: the steel plates placed behind the rod 2', and by the oblique motion of the
carriages. This plate ¹ is screwed on the iron band or fillet k¹ itself, fixed by
two small columns to the slab which carries the carriages. The plate is so
arranged that the rod placed on the cross piece which unites the levers
receives an impulsion forward each time that the carriage makes the oblique
movement required in cutting the pegs. This impulsion constitutes the motion
which causes the claws to advance. The spiral spring placed inside the
carriage above the claws produces the movement, which causes them to retire.
The claws are held on the carriage in front by the cross piece m¹, and at the
back by the screws n' placed in the slotted holes made in the claws, in order to
obtain the come-and-go motion. The cross piece m' and the screws n', being
solely intended to uphold the claws, should leave them all the free play possible.
In front of the claws 6' and on the carriage are placed two moveable guides o',
intended to support the sheet metal; they are fixed to the carriage forward by
two screws with nut sliding in a slotted hole, an arrangement which permits
their being placed closer or further apart, according to the width of the bands
of sheet metal, and at the back by the cross piece p² provided with a press
screw and placed on the two guides. This counter traverse or cross piece
carries a shoulder, which serves to maintain the pressure of the springs q¹ when
the carriage is unprovided with sheet metal. The springs q¹ press on the
guides in order to prevent the return of the sheet metal, and this result is
obtained by means of the crotchet teeth at the hind part of said guides. These
guides are composed of two steel plates so riveted together that the under
one is covered by the upper, and forms a slide with the bottom of the carriage.
I will now describe the cam pulley d, Figures 7 and 7*, and its advantages.
The distinctive character of this pulley consists in a groove running twice round
it in crossing, as shewn, Figures 1 and 5. This crossing gives an alternate
come-and-go motion to the slide block e by means of the shuttle with tempered
steel spindle."', sliding in the cast-iron groove s¹, as shewn, Figure 7. The
principal and essential object of this pulley is to render the oblique motion of
the carriages alternate, precise, and invariable, so that the cutting of the pegs
can only take place when the carriages are in absolute repose, a result affording
a great advantage in the manufacture, inasmuch as by this means pegs of the
same number or denomination are always of equal length. The working of
this pulley differs from that of a cam, in that the cam would effect the come-
and-go of the slide block in one turn, whereas the pulley makes two turns for
this object, at the first turn of the pulley the slide block being drawn forward,
the carriages are placed obliquely to the right, and the peg is immediately cut;
this pulley being keyed on the shaft which moves the shears at the second
9

page_text: turn pushes back the slide block, the carriages move obliquely to the left, the
shears again fall, the pegs are cut, and so on continuously. The crossing of
the groove may be lengthened or shortened, as may be deemed necessary.
This cam pulley being entirely of my Invention, I reserve the exclusive right
to use it not only in the machine above described, but in any other machine
to which it may be found applicable. It will be understood that the crossing
of the groove may not only be changed, but that several may be added, and
the diameter be varied.
In witness whereof, I, the said François Rigollot, have hereunto set
my hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and sixty-two.
