LEON ALPHONSE DENILLE pere, of Creil (Oise) France, Nail Manufacturer
do hereby declare the nature of this invention to be as follows:-
My invention relates to machines for the manufacture of tacks, rivets, pins, and
the like.
The improved machine is essentially characterized by the arrangement of the parts,
which arrangement enables two, three or a greater number of tacks or similar articles
to be made simultaneously with the same tool.
Attempts have heretofore been made to produce several tacks or the like simul-
taneously by arranging in one machine as many tools as there are tacks to be made,
these tools being actuated by single driving mechanism, which renders the machine
more complicated and cumbersome than the machines of ordinary construction.
My invention has for its object to produce in a given time by means of a single
machine a quantity of work equal to that produced by two three or even a greater
number of ordinary machines of ordinary construction.
:
My improved machine is preferably fed by a number of reels equal to the number
of tacks to be formed I may however use any other convenient inode of feeding.
especially in case my tacks are of a polygonal section or are cut and formed of rolled.
metal of any section.
In fact my improved machine is applicable, as will be readily understood, to the
manufacture of rivets, nails of any kind, pins and the like.
In order to make my invention well understood I have represented the improved
machine which forms the subject thereof, in the accompanying drawing, but by way
of example only.
In the drawing
Figure 1 represents a side elevation of the whole of the machine.
Figure 2 is a plan of the same as seen from above.
Figure 3 shows to an enlarged scale a diagram of the work performed by my
machine arranged for making three tacks simultaneously.
In these figures the same letters of reference designate the same parts.

page_text: It may be observed in the first place, and this is the essential feature of the inven-
tion, that the machine does not comprise other elements than the machines which
make only one tack at a time but these clements are combined differently and
arranged to enable a double or triple quantity of work to be performed, in the same
time which cannot be done with the existing machines.
In my improved machine as in single work, the crushing of the heads of the series
of tacks is obtained by the triple punch a fitted to the ram b which can be actuated
either by the helical springs c or by springs having wooden blades, or by any other
appropriate mechanical means.
During the formation of the head the rod is kept pressed between the jaws or
clamps d, d, the former of which is movable and the latter fixed. The movable jaw
is actuated by the lever e pivotted at f and moved by the cam g fixed upon the
driving shaft h; this lever e can however be replaced by any other equivalent
device.
The wires receive a forward motion equal to the length of the tack by means
of the pincer & actuated by the connecting rod keyed upon a disc k and pro-
vided with means whereby the stroke of the pincer can be regulated according to
the length of the tacks or other articles to be manufactured.
The triple knives 1. afterwards separate and form the tack. These knives are
actuated by the levers m pivotted at m¹ upon the same cross piece n as the lever c.
The levers m of the knives are actuated by the double cain m³ keyed upon the
driving shaft h and the central part of which serves at the same time to drive the
ram.
When the tacks are thus cut the hammer which may or may not be provided
with an arm at its lower part forces the plunger a away from the block d and
allows the three tacks to fall into the box p placed under the frame to receive the
work.
The driver hammer is constructed with an arm 7 mounted upon a small inter-
mediate axis provided with a double antagonistic spring; a second arm is prolonged
behind the axis r so as to bear upon the cams which causes the hammer to descend
at each revolution of the driving shaft upon which it is fixed.
For the rest of the machine it will be seen to consist of a frame t similar to the
framo of a machine used for a single tack; the said frame is inclined towards the
front, and carrying by means of brackets u, the driving shaft h with the cams above
described, the transmitting pulleys and the fly wheel a.
Lastly a straightening device y fixed to the front end of the frame and provided
with pulleys, having three grooves through which the wires pass when being fed from
the reels into the machine.
The tools, that is to say the jaws d and the knives are formed of hardened pieces
of steel and are of trapezoidal section.
The said tools are of a certain length, and can often be recut before passing to the
waste. Adjusting screws serve to compensate for the wear and to determine their
relative position.
The stop mechanism for the fixed jaw d¹ comprises a gudgeon having a lever,
retained by a tappet d³ and constituting a kind of keying device which permits
the tool holder to be instantaneously dismounted and remounted without having
to dismount the other parts of the mechanism.
It is evident that according to the kind of articles to be produced I can employ
brass, iron, wire puddled iron, and the liko, without departing from the principle of
the machine.

I, LEON ALPHONSE DENILLE père, of Creil (Oise) France, Nail Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to machines for the manufacture of tacks, rivets, pins, and
the like.
The improved machine is essentially characterized by the arrangement of the parts;
which arrangement enables two, three or a greater number of tacks or similar articles
to be made simultaneously with the same tool.
Attempts have heretofore been made to produce several tacks or the like simul-
taneously by arranging in one machine as many tools as there are tacks to be made,
these tools being actuated by a single driving mechanism, which renders the machine
more complicated and cumbersome than the machines of ordinary construction.
My invention has for its object, to produce in a given time by means of a single
machine, a quantity of work equal to that produced by two, three, or even a greater
number of machines of ordinary construction.
My improved machine is preferably fed by a numbor of reels equal to the number
of tacks to be formed; I may however use any other convenient mode of feeding,
especially in case my tacks are of a polygonal section or are cut and formed of rolled
metal of any section.

In fact, my improved machine is applicable, as will be readily understood, to the
manufacture of rivets, nails of any kind, pins and the like.
In order to make my invention well understood I have represented the improved
machine which forms the subject thereof, in the drawing left with the provisional.
specification but by way of example only.
In this drawing
Figure 1 represents a side elevation of the whole of the machine.
Figure 2 is a plan of the same as seen from above.
Figure 3 shows to an enlarged scale a diagram of the work performed by my
machine arranged for making three tacks simultaneously.
In these Figures the same letters of reference designate the same parts.
It may be observed in the first place, and this is the essential feature of the inven-.
tion, that the machine does not comprise other elements than the machines which
make only one tack at a time but these elements are combined differently and arranged
to enable a double, triple or other quantity of work to be performed in the same time
which cannot be done with the existing machines.
In my improved machine as in single work, the crushing of the heads of the series
of tacks is obtained by the triple punch a fitted to the ram b which can be actuated
either by the helical springs c or by springs having wooden blades, or by any other
appropriate mechanical means.
During the formation of the head the rod is kept pressed between the jaws or
clamps d'd the former of which is movable and the latter fixed. The movable jaw

shaft h; this lever e can however be replaced by any other equivalent device.
The wires i receive a forward motion equal to the length of the tack by means of
the pincer k actuated by the connecting rod ¹ keyed upon a disc and provided with
means whereby the stroke of the pincer can be regulated according to the length of
the tacks or other articles to be manufactured.
The triple knives / separate afterwards and form the tack. These knives are
actuated by the levers m pivotted at m³ upon the same cross piece n as the lever e.
The levers m of the knives are actuated by the double cam m³ keyed upon the
driving shaft and the central part of which serves at the same time to drive the
ram.
When the tacks are thus cut the hammer o which may or may not be provided
with an arm at its lower part forces the plunger a away from the block d and
allows the three tacks to fall into the box p placed under the frame to receive the
work.
The driver hammer is constructed with an arm q mounted upon a small inter-
mediate axis provided with a double antagonistic spring, a second arm is prolonged
behind the axis 7 so as to bear upon the cam & which causes the hammer to descend
at each revolution of the driving shaft upon which it is fixed.
For the rest of the machine, it will be seen to consist of a frame t similar to the
frame of a machine used for a single tack; the said frame is inclined towards the
front, and carrying by means of brackets u, the driving shaft with the cams above
described, the transmitting pulleys v and the fly wheel .c.
Lastly a straightening device y fixed to the front end of the frame and provided
with pulleys, having three grooves through which the wires pass, when being fed from
the reels, into the machine.
The tools, that is to say the jaws d and the knives are formed of hardened pieces
of steel and are of trapezoidal section. They are of a certain length, and can often
be recut before passing to the waste. Adjusting screws 1 serve to compensate for the
wear and to determine their relative position.

I conclude by describing the stop mechanism of the fixed jaw d¹ obtained by means
of a gudgeon d having a lever, retained by a tappet d³ and constituting a kind of
keying device which permits the tool holder to bo instantaneously dismounted and
remounted without having to dismount the other parts of the mechanism.
It is evident that according to the kind of articles to be produced, 1 can employ
brass, iron wire, puddled iron, and the like, without departing from the principle of
the machine.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a machine for the simultaneous manufacture of several tacks, the combination
of a wire straightening device y of a pincer k presenting the wires in the same
vertical plane, of fixed and movable jaws or clamps d, of knives 1, and of the tack
hammer o, the whole arranged to effect the driving of the tacks by a single
descending motion of the tack hammer o as above described with reference to the
drawing.
