page_text: segments will have passed so far beyond a line drawn between the said axes as to
leave an open space between them at the lower end of the face of the segments,
as seen in Fig. 1, and so that when in the down position, as seen in Fig. 2, there
will be a similar opening between the segments, but as the segments move from one
position to the other, their faces will work in close contact, like a pair of rolls
running in contact.
In the face of each of the segments a groove R, is formed, as seen in Fig. 4, the
shape of these grooves combined corresponding to the shape of the reduction
required for the wire or of the article to be produced.
Over the segments a projecting head S, is formed on the frame, through which a
vertical tubular spindle T, is ranged, in a line between the faces of the two
segments. The tubular spindle T, is adapted to receive the wire-holder which
carries the wire or rod to be reduced, and is arranged to receive a vertical recipro-
cating movement.
In the head S, is a tubular sleeve U, threaded upon its exterior surface, and
through which the spindle T, passes, and so as to work freely up and down therein.
The sleeve U, extends down into the head, and is arranged so as to slide up and
down therein. At its lower end it is provided with a toothed wheel V, arranged
at right angles to the axis of the sleeve, and so that the sleeve will work up and
down through the wheel, while the wheel is free for rotation, but held against
vertical movement, and between the wheel V, and the sleeve is a spline, not shown,
or other suitable device, whereby the said sleeve while movable up and down
through the wheel, will partake of a rotation imparted to the wheel.
In the head S, below the wheel V, is a second similar toothed wheel W; through
which the tube R, passes, but so as to move freely up and down through the wheel,
but engaged with the wheel for rotary movement as described for the wheel V, and
its sleeve.
The upper portion of the sleeve U, is screw-threaded, and projects up through
and above the top of the head S. On the top of the head S, a lever X is
arranged, upon a pivot Y, and so as to swing in a horizontal plane, combined
with a spring Z, the tendency of which is to force the said lever toward the screw-
threaded sleeve, the lever at one point a being adapted to engage the thread of
the screw-sleeve, and so that when so engaged, a rotary movement imparted
to the sleeve through the wheel V, will cause the sleeve to move up or down,
according to the direction in which the rotation is produced, or when the lever
is turned away from the sleeve, as represented in broken lines Fig. 5, the sleeve
will be disengaged, and so that it may be moved up or down at pleasure.
A spring, is arranged between the head S and the sleeve, the tendency of
which is to raise the said sleeve when the sleeve is free from engagement with the
lever X. As here represented, the spring engages the sleeve beneath an annular
flange c, and so that the spring lifts upon the said flange to raise the sleeve, but
yields as the sleeve descends. The spindle T, is constructed with a collar d, above
the sleeve U, and so that the spindle in its down position may come to a bearing
upon the upper end of the sleeve U, as represented in Fig. 2, the said collar coming
in contact with the upper end of the sleeve U, limits the extent of descent of the
spindle.

To impart an intermittent rotary movement to the sleeve U, the wheel V, is
constructed as a ratchet, and below it is a toothed wheel e, free to revolve inde-
pendent of the wheel V. The toothed-wheel e, carries a pawl F, which is adapted
to engage the teeth of the wheel V. A horizontal reciprocating rack 3
arranged to engage with the toothed wheel e, and impart an oscillating movement
thereto. The reciprocating movement is imparted to the rack g through a two-
armed or bell-crank lever i, hung upon a pivot k, and so as to swing in a
plane parallel with the toothed rack g, one arm being engaged with the said
rack, while the other arm i, stands in the path of the arm 0, of the segment I,
and so that as the said arm 0, rises, it will strike the arm i, and impart an
intermittent movement to the rack g, as from the position in Fig. 1, to that

page_text: seen in Fig. 2. A spring, serves to return the said lever h i, and the rack g.
As the rack g, is forced inward, as described, it will impart a corresponding
rotation to the toothed wheel e, in the direction indicated by the arrow Fig. 7;
in this operation the pawl will engage the teeth of the wheel V, and impart
to that wheel V and the sleeve U, a corresponding rotation, then as the slide
returns, the wheel e, will return, but the pawl will escape the teeth of the
wheel V, and so as not to impart to the wheel V and its sleeve a return
rotation, consequently under the continued reciprocation of the rack g, a step by
step or intermittent rotation will be imparted to the sleeve U, and the screw-
thread of that sleeve being engaged with the lever X, such rotation will impart to
the sleeve a corresponding step by step downward movement.
The wheel W, receives a similar step by step rotation through a two-armed or bell-
crank lever mn, hung upon a pivot o, the arm m being in connection with a recipro-
cating toothed rack p, which works into a corresponding toothed wheel which
carries a similar pawl r, to work into the wheel W, in like manner as does the
pawl into the wheel V. The arm of the lever m n, stands in the path of the
arm O, of the segment I, in like manner as described for the arm i, of the other
lever. The lever m n is provided with a springs, to give to it its return movement,
the same as described for the spring 1, of the other lever.

An up and down vertical movement is imparted to the spindle T, independent of
the sleeve U, such movement being produced through a lever u, hung upon a
said lever swinging in a vertical plane, one arm of the said lever engages
with the lower end of the spindle T; as here represented this engagement is
produced by constructing the arm of the lever u, with a forked end, and placing
upon the lower end of the spindle T, a collar w, which will permit the free
rotation of the spindle, but yet engage the spindle so that the spindle will move up
and down with the collar. From the collar w, a pin a, projects into a vertical
groovey, in the frame in rear of the collar, which groove and pin prevent the
rotation of the collar, yet permits the up and down movement of the collar and
spindle, the forked end of the lever u, embraces the pin a, and so that as the
lever u, swings up and down, as from the position in Fig. 1, to that in Fig. 2, and
return, a corresponding vertical reciprocating movement will be imparted to the
spindle T.
From the other arm of the lever u, a rod 2 extends down through a lug 3, on the
arm P of the segment J, see Fig. 3. Upon the rod 2, below the lug 3, an
adjustable nut 4 is applied to the rod, the rod being free in the lug, and so that the
lug may slide freely upon the rod. Upon the rod 2, above the lug, a spiral spring 5,
is arranged, and so that as the arm P of the segment J, rises, it will strike the
lower end of the spring 5, and through such spring tend to turn the lever u, so
as to force the spindle T, downward, as seen in Fig. 2, while on the return or
descent of the arm P, of the segment J, the lug 3 will strike the nut 4, as the
said arm P approaches its downward position, and as seen in Fig. 1.
The nut and spring arrangement of the rod 2, gives a considerable amount of
lost motion between the arm P, and the lever u, so that the said lever u, and the
spindle T, have a considerable freedom or independence of the swinging movement.
of the segments.
The holder which carries the wire or rod to be operated upon, is represented
detached in Fig. 8, the said holder 6, is of an external diameter corresponding
substantially to the internal diameter of the spindle T, and of a length preferably
somewhat greater than that of the said spindle, and is provided with means for
engagement with the spindle so as to partake of both the reciprocating and
rotating movement of the spindle. At the lower end the holder is split, as at 7,
and so that it being elastic, it may be contracted, or otherwise constructed so as
to be contracted to firmly grasp the wire or rod which may be passing through it.
At the upper end the holder is constructed with a collar 8, adapted to rest upon
the upper end of the tube T, and is also provided with a spring-latch 9, which is
adapted to engage with the spindle so as to interlock the two therewith, that the

page_text: holder may partake of the movement of the spindle, as before described. This
completes the construction of the machine. Its operation is as follows.
The sleeve U, is adjusted to its up position, the segments I and J standing in
their down position, as seen in Fig. 2, the wire or rod is introduced into the holder 6;
and the holder with the rod is passed through the spindle T, the wire or rod pro-
jecting through the holder, and so that upon such introduction, the lower end of
the spindle will enter the space between the ends of the two segments, as seen in
Fig. 2. The spindle with the holder is held in this down position by the lug on
the arm. P of the segment J, bearing against the spring 5 of the rod 2, so as to
turn the spindle-lever to its down position, holding it there with the yielding force
of the spring 5. Now the swinging movement is imparted to the segments IJ,
causing them to rise, and in so doing their faces come together and engage that
portion of the rod which stands between them, and so as to compress it in the
groove in the face of the dies, and so that that portion of the rod will assume the
shape of the portion of the groove in which it stands. As the segments rise and.
thus grasp the rod, the upward force will cause the spindle and holder to rise with
them, so long as the faces of the segments stand together, but so soon as the
segments have passed so far up that the portion of the wire operated upon is free
from contact with the groove in the faces of the segments, then the rod. and the
holder:are free, and as the segments approach their extreme up position, the lug 3,
will strike the nut 4 on the lower end of the rod 2, and return the spindle and
holder. to the up position, as seen in Fig. 1, and while the holder and spindle are
in this.up position, the segments I and J commence their return or downward move-
ment, and as the arm N in this turning of the segments approaches its up position,
it.will strike the arms in of the feed-levers, turning those levers from the position
seen in Fig. 1, to that seen in Fig. 2, and thus impart to the racks and their
inward movement,, the rack g imparting to the sleeve U a corresponding rotation,
and which. rotation will cause the sleeve U to descend according to the pitch of
its.screw-thread, while the other rack p, will have imparted a partial rotation to the
spindle T, with the holder and rod which it carries.
The descent of the spindle is arrested by the collar d at its upper end coming:
against the upper end of the sleeve U, so that as the second descent of the spindle.
is made, it will drop as much farther than in the first operation as the sleeve U, has
descended,, and a corresponding additional projection of the wire or rods between
the segments will have been produced, so that on the second operation, additional
metal, will be presented for the operation of the segments, and also the rod will be
presented. in a different position circumferentially, owing to the rotation which has
been imparted to the spindle T, and so continuing, each operation will introduce
the rod to a greater extent between the two segments, and the rotative movement.
will present that metal in a new position circumferentially at each operation.
The segments.continue their vibration and the descent and rotation of the rod.
or wire continues until the required result is attained, that is, until the required.
reduction is made, or the article to be produced is properly shaped.
The representation of the shape in Fig. 4 is that required.for an awl or punch,,
and is sufficient to. illustrate the operation of the invention.
When one reduction or article has been completed, it is cut from the. rod,
and, the rod re-presented, for a second reduction or formation of the second
article..
The upward movement of the segments is preferably made so far as to entirely
separate them in their up position, as seen in Fig. 1, in order that the grip of the
segments upon the wire or rod may be entirely released, so that the ascent of the
rod for a. new feed is insured under all circumstances, and so that if desired.
the segments, may operate upon the rod. until it projects or extends below the lower
face, as for illustration, if it be desired to simply reduce a rod of equal transverse
area.and.of.unlimited length, the,downward.feed and rotation would continue, until
the, required. length is attained,, the, segments, opening in, their extreme upward
movement,, will. permit the rise of the rod for a new feed,, notwithstanding, the

page_text: fact that the portion previously operated upon extended far below the lower end
of the segments.
By introducing the rod between the entrance ends of the segments while those
ends are open, the said entrance ends of the segments being upon that side of the
segments towards which they are to swing in operation, and so as to grasp but a
small portion of the rod at the first operation, the extent of surface grasped
increasing at each operation, the reduction is produced in a similar manner to that
of a smith in hand forging, and whereby the liability of splitting the metal, which
necessarily follows the reduction of the wire or rod when introduced between the
working surfaces from the side opposite that toward which the segments are
moving, is avoided.
In the illustration the dies are represented as for making a reduction round in
transverse section, it may be desirable to reduce the rod in angular shape, as square
in transverse section; in such case the grooves in the face of the segments will be
made accordingly, and the rotative movement imparted to the spindle will be made
to correspond to the shape of the reduction required, so that the angle will be
properly presented between the segments.
The segments operating as I have described for the introduction of the rod to
be reduced between the open segments, and on that side of the segments towards
which they advance for operation, may be employed with various kinds of inter-
mittent advancing feed well known in the art, or the presentation of the rod and
feed may be made by hand, the operator presenting the rod and rotating it as
described for the automatic apparatus, I therefore do not wish to be understood
as limiting the invention to the necessary employment of an automatic feed, or to
the particular construction of the intermittent automatic advance and rotative feed
which I have described.

tion, and in what manner the same is to be performed, as communicated to me by my
