page_text: the other direction by a spring K, which is suitably connected with the said arm and
the frame A. The plate G₁ is guided by the table A¹ and locates the guide and
cutter G in position to direct the wire to a support or die L, which depends from the
table A¹, and has a horizontal opening c, to receive the wire, and a vertical opening d,
the latter permitting the wire to be bent by means of a plunger M, which is attached
to a head N, and passes through an opening in the table A¹ and is adapted to enter
the opening d, said head N being connected with a yoke N¹, which is operated by an
excentric P, on the shaft B, whereby as the plunger is depressed the wire on the die L
is bent and forced through the opening d, the bent wire in somewhat staple form then
being pushed into a holder and carrier Q, which consists of a horizontal arm located
below the table, formed with a vertical opening e, and attached to a vertical shaft R
said opening in one position of the holder being directly beneath the opening d of the
support L.
In order to impart rotary reciprocating motions to the shaft R, and thus operate
the holder said shaft having its bearings on the table A³, I attach to the upper end
of the shaft a pinion, R¹ with which gears a toothed segment S, and to said pinion
is secured one end of a spring R", whose other end is fixed to a stationary part of the
frame A on the table A'. The segment S is secured to an arm S₁, which is pivoted to
the frame A, and engaged by a cam S", on the shaft B, so that when the arm is moved
in one direction, by said cam S" the segment rotates the pinion, and this operates the
holder Q and winds the spring R". When the cam leaves said arm S¹, the spring is
permitted to unwind, thus imparting motion to the holder Qin the opposite direction
and rotating the pinion R¹, so as to restore the arm S₁ to its normal position ready to
be engaged by the cam S".
Connected with the table A' on the under side thereof are shaping dies T, the faces
of which are grooved relatively to the form to be imparted to the staples. Between
the faces of the dies is fitted a vertically-moving plunger T¹; whose head T" is engaged
by a cam T on the shaft B. Below the dies T is a punch U, which attached to a
head V, is located in a right line with the plunger T', said head being attached to a
vertically-moving shaft W, which is guided in the table A¹ and frame A and raised
and lowered by means of a yoke X, which, connected with said shaft, is operated by a
cam Y, keyed or otherwise secured to the shaft B..
The head N, holder Q, and head T¹¹ are adjustable, in order to properly time the
work and adapt the machine to the formation of staples of different lengths.
The operation is as follows: Power is imparted to the shaft B by the pulley Z or
other suitable means, and the wire is fed between the rollers C C and directed through
the guide G and placed on the block or die L stretched across the opening d. The
plate G is then lowered, and as it passes along the side of the die L it acts as shears,
and thus cuts the wire the required length. The plunger M now descends and bears
against the wire and bends the same centrally, forcing the bent piece through the
opening d, causing the wire to be drawn, instead of having part of its stock cut away,
and placing it in the holder, as shown in Figure 2. The segment S now rotates
the pinion R, whereby the holder Q is carried away from the support L and placed
beneath the dies T, the plunger T₁ being in its lowest position. The punch U now
rises and presses the. bent wire of staple shape upwardly and simultaneously there-
with, the holder Q is stripped of the wire and returns to its first position by the
action of the spring R". The punch forces the bent wire into the dies T, the legs
of the wire passing between the plunger T¹ and faces of the dies, and the plunger is
caused to rise by the action of a spring U', whereby the wire receives its complete
staple shape. The punch U now lowers, and as the plunger T¹ is depressed the staple
is forced downwardly from the dies and ejected therefrom. Meanwhile another length
of wire is advanced by the rollers C into the guide and cutter G, and the subsequent
operations are a repetition of those herein before stated.
The guide and cutter G is shown of the form of a tube threaded exteriorly, and
engaging with a threaded opening in the plate G₁; but it may have a set screw
whereby when the cutting edge of the tube wears away the tube may be readily moved
close to the support L, or entirely removed for sharpening purposes.

page_text: The contour of the depressions in the faces of the dies T is such that the legs and
the crowns of the staples are properly shaped and the legs nicely pointed.
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
First. In a machine for forming wire staples, the die L, having a vertical opening,
in combination with a plunger M, movable arm Q, having opening e, and oscillating
shaft R, substantially as described.
Second. In a machine for forming wire staples, a holder for the wire, and a
bending and reducing plunger, in combination with a movable arm Q, for carrying
the bent wire to the staple-shaping dies, substantially as and for the purpose set
forth.
Third. In a machine for forming wire staples, a support for the wire, a bending
plunger, and shaping-dies, in combination with an oscillating holder, having adjustable
arm, carrying the bent wire as it leaves said die to the shaping-dies, substantially as
and for the purpose set forth.
Fourth. In a machine for forming wire staples, a holder or carrier for the primarily
shaped staple, in combination with an oscillating shaft, a pinion, toothed segment, and
returning spring, substantially as and for the purpose set forth.
Fifth. In a machine for forming wire staples, staple shaping dies, a plunger between
the dies, and a punch for forcing the primarily-shaped staple into said dies and
completing the shape thereof, combined and operating substantially as and for the
purpose set forth.
Sixth. In a machine for forming wire staples, feed-rollers, a cutter, a support for the
wire, a bending plunger, a die, a holder and carrier for the bent wire, staple shaping and
pointing dies, a plunger within the dies, and a punch for forcing the bent wire into
said dies, said parts being combined and operating substantially as and for the
purpose set forth.
薯
Seventh. Feed rollers, a cutter, a support for the wire, a bending plunger, a die, a
holder, and carrier for the bent wire, staple shaping and pointing dies, a plunger within
the dies, and a punch for forcing the bent wire into said dies, in combination with
connected arms and heads, and excentrics, and a cam, said excentrics and cam being
on the same shaft, substantially as and for the purpose set forth.
