PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Nails, Tacks, or
similar articles.
I, THEODORE LÉON RIVIERRE of Creil, Oise, France, Manufacturer do hereby
declare the nature of this invention to be as follows:-
My invention has reference to apparatus for the manufacture of nails, tacks and
other similar articles more particularly with hollowed out sides, from wire.
The improved apparatus comprises the following parts: A frame, a driving shaft
on which are mounted a fly wheel and fast and loose pulleys, an ordinary nipper or
gripper for conducting the wire, this device being worked by a crank; a reducing
apparatus, a ram fitted with a punch or hammer; a set of jointed pieces for operating
the ram; two knife or cutter carriers; two levers for effecting the cut worked by
two cams; and a reducing lever worked by a cam. The set of jointed pieces above
referred to worked by a cam and is composed chiefly of two link-like parts one
of which is fitted at its centre with a roller upon which the cam acts; these two
link-like parts are connected together by a pin. One of the said link-like parts is
connected by another pin to another piece the position of which on the frame can
be regulated by means of a screw; the other link-like part is connected by a pin to
the ram.
When the cam which operates these parts is in one position the parts
are straightened out and the punch acts on the reducing piece; when on the other
hand the cam is in the reverse position the jointed parts contract and the punch is
withdrawn.
The reducing apparatus is composed of two pieces one of which is moved by the
reducing lever. The said pieces have recesses in which tenons with inclined faces
are placed the position of these tenons being adjustable by means of screws.
Against the inclined faces the tools abut and these converge to the same point when
the two pieces of the reducing apparatus are made to approach each other and
separate when the two pieces are moved apart and in these movements they present
a pyramidal or tapered section. The tools are for this purpose slightly tapered on
the edge which produces the pyramid or taper and the corners are slightly depressed
so as to produce the hollowing out of the sides of the nails or tacks.
The action of the apparatus is as follows: The wire is conducted by means of
the nipper hereinbefore described which is similar in its form and action to those
hitherto employed for analogous purposes. The wire enters the reducing apparatus
which is at this time open and it is taken hold of thereby. The reduction is then
effected so as to form a nail body or shank of pyramid or taper form and of a
square, triangular or circular section with hollowed out sides and the punch or
hammer at the same time strikes the end of the wire so as to form the head which
may be either flat or rounded. The wire is then pushed forward by the nipper
the desired length, and the knives sever it, at the same time forming the point.
Dated this 27th day of January 1891.

Improvements in Apparatus for the Manufacture of Nails, Tacks, or
similar articles.
I, THEODORE LÉON RIVIERRE of Creil, Oise, France, 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 has reference to apparatus for the manufacture of nails, tacks and
other similar articles, more particularly with hollowed out sides from wire.
The improved apparatus is represented in plan in Figure 1 of the annexed
drawings and in longitudinal section in Figure 2. Figure 3 represents the jointed
mechanism for operating the ram and Figure 4 is a front view of the reducing
apparatus.
The improved apparatus comprises the following parts:-A. frame A.; a driving
shaft B on which are mounted a fly wheel V and fast and loose pulleys P, P¹ an
ordinary nipper or gripper C for conducting the wire, this device being worked by
a rod D a reducing apparatus E; a ram F fitted with a punch or hammer G; a
set of jointed pieces H for operating the ram; two knife or cutter carriers I; two
levers J for effecting the cut worked by two cams ; and a reducing lever L
worked by a cam M. The set of jointed pieces H (shown separately in Figure 3)
is worked by a cam N and is composed chiefly of two link-like parts a and b one of
which, is fitted at its centre with a roller upon which the cam N acts; these
two link-like parts are connected together by a pin d. The part a is connected by
another pine to another piece the position of which on the frame can be regulated
by means of a screw y; the other part is connected by a pin to the ram.
When the cam which operates these parts is vertical, as seen in Figure 2, the parts
are straightened out and the punch acts on the reducing piece E; when on the
other hand the cam is in the reverse position the jointed parts contract to the
position seen in Figure 3 and the punch is withdrawn.
The reducing apparatus E (see Figure 4) is composed of two pieces i and jone
of which is moved by the reducing lever L acting on the part. The said pieces
have recesses in which teuons with inclined faces are placed the position of these
tenons being adjustable by means of screws m. Against the inclined faces the
tools abut and these converge to the same point o, when the two pieces ij of the
reducing apparatus are made to approach each other, and separate when the two
pieces are noved apart, and in these movements they present a pyramidal or tapered
section. The tools are for this purpose slightly tapered on the edge which
produces the pyramid or taper and the corners are slightly depressed so as to
produce the hollowing out of the sides of the nails or tacks. One of the tools, that
marked n', serves as the meeting point for the others and does not require an
inclined face to move it, it is regulated directly by the screw m³.
The action of the apparatus is as follows: The wire is conducted by means of
the nipper C which is similar in its form and action to those hitherto employed for
analogous purposes. The wire enters the reducing apparatus E which is at this
time open and it is taken hold of thereby. The reduction is then effected so as to
form a nail body or shank of pyramid or taper form and of a square, triangular or
circular section with hollowed out sides, see t Figures 5, 6 and 7, and the punch or
hammer G at the same time strikes the end of the wire so as to form the head r,
which may be either flat or rounded. The wire is then pushed forward by the
nipper the desired length, and the knives sever it, at the same time forming the
point s.

page_text: 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 :-
1. In a machine for manufacturing nails, tacks or similar articles with hollowed
out sides from wire, a reducing apparatus as specified for forming the body or
shank in combination with a punch or hammer worked as described for forming the
head and with knives for severing the wire and forming the point, substantially as
hereinbefore described and represented in the annexed drawings.
2. The jointed mechanism, substantially as described, for giving movement to the
punch or ram under the action of the cam N so as to produce the head of the nail
or other article, as set forth.
3. The reducing apparatus E, constructed substantially as described, for com-
pressing or reducing from wire a pyramidal or tapered nail or tack body or shank
with hollowed out sides, as set forth.
