the corresponding resilient seats 28 and 29,
said pins normally projecting behind the
corresponding shoulders 22 and 23. A rack
member 30 is provided, which is in mesh
5 with the gear wheels 21 and which is recip-
rocated through the link 31. One end of
this link is pivoted to said rack member and
the other end thereof is pivoted to one end of
the arm 32, which is integral with the shaft
10 33, this last-mentioned shaft being rotatably
mounted in suitable bearings 34, 34 carried
by the frame 2. The shaft 33 also has the
arm 35 extending at right angles thereto and
the free end of which has a roller bearing
15 36 arranged in the path of the cam 37 car-
ried by the back of the disk 12 and when said
cam contacts with said bearing it operates to
partially rotate the shaft 33 and exert a
downward pull on the rack member 30,
20 thereby rotating the gear wheels 21 one-third
of a revolution. The pins 26 engaging be-
hind the shoulders 22 force the clutch disks
20 and the shafts 19 on which they are
mounted, to perform one-third of a rotation
25 and the pins 27 during this movement are
depressed by the sloping sides of the shoul-
ders 23 until they drop behind the abrupt
sides of said shoulders and lock the shafts 19
against backward rotation. The shaft 33
30 has a torsional spring 38 coiled therearound
one end of which is secured to the shaft and
the other end to its bearing. When the cam
37 has passed the bearing 36 this spring will
operate to reverse the movement of the link
35 31, causing the rack member to move up-
wardly, reversing the rotation of the gears
21 and carrying the pins 26 back until they
engage behind the next succeeding shoulder
22. The inner end of each of the shafts 19
40 has two disks 39 fixed thereon and spaced
apart, each of said disks having three pe-
ripheral alined notches 40 to receive the wire,
said notches being spaced a uniform distance
apart.
4r Tension levers 41. 41, 41 are provided,
which are pivoted to the frame 2. One end
of each lever is arcuate and rests between the
corresponding disks 39 and the opposite ends
of the levers have vertically alined orifices
50 through which the rod 42 extends loosely,
said rd having nuts 43 secured. thereon and
normally in contact with the ends of the cor-
responding levers 41. Pivoted to this rod is
the lever 44, which is fuicrumed upon the
55 frame 2 and whose outer end has a roller
bearing 45 arranged in the path of the de-
pression 46 which is in the periphery of the
disk 12. The bearing 45 normally rest:
against the periphery of the disk 12 whicl:
60 operates through the lever 44 the rod 42 and
the tension levers 41 to hold the arcuate ends
of said last-mentioned levers firmly against
the wires resting in the notches of the disks
39. The mechanism is so geared that when
65 the twister hooks 6, 6, 6 begin to turn thedepression 46 will be opposite the bearing 45
and the tension on. said levers 41 will be re-
leased. The wires will thus be firmly held in
said disks when the hooks are stationary but
when they begin to turn the tension will be 70
released, permitting a certain amount of
slippage so as to prevent breaking of the
wires by the turning of said hooks. Ar-
ranged alongside the twister hooks are the
vertical cutter bars 47 and 48, the former of 75
which is fixed to the frame and the latter of
which has vertical slots 49, 49 therethrough
through which the bolts 50, 50 extend.
These bolts are secured to the bar 17 and
have enlarged heads to secure the bars to- 80
gether and permit the vertical movement of
the latter relative to the former. These bars
have alined notches 51, 51, 51 opposite the
twister hooks 6, said notches having con-
verging cutting edges and the respective 85
disks 39 carry the corresponding wires into
said notches. Fixed to the bar 48 are the
laterally extending wings 52, 52, 52, ar-
ranged slightly above the corresponding
notches 51, and the wires are carried by the 90
needles 53 underneath said wings, which op-
erate to cause the wires to engage around
the hooks 6 as is illustrated in Fig. 6. Ar-
ranged underneath the wings 52 and in
alinement therewith are the stripper hooks
54, 54, 54, which are also fixed to the bar 48,
These hooks engage underneath the wires
and strip the twisted ends thereof from said
hooks when the bar 48 is moved upwardly
as will presently be described. 100
Rotatably mounted in the bearing 55, car-
ried by the frame 2 is a shaft 56 and fixed
to the respective ends thereof are the oppo-
sitely extending arms 57 and 58. the free end
of the latter of which is pivoted to the lower 105
end of the bar 48 and the free end of the
former of which has the roller bearing 59.
which projects into the eccentric groove 60
in the face of the disk 12. This groove is
cam shaped and is formed so that its outer 110
wall will bear against the bearing 59 and
after the knot is formed will force the free
end of the arm 57 in toward the center of
the disk 12, thereby elevating the free end
of the arm 58 and the bar 48 connected 115
thereto thus severing the wires resting in the
notches 51 and stripping the twisted wire off
the twister hooks 6. 6, 6, and said groove is
so formed as to hold said bar temporarily
in its elevated position while the needle 53 is 120
being withdrawn so that the wire as it is ca'-
ried back by the needle will engage against
the outer end of the corresponding hook 54,
and is there held until the bar descends.
when said wire passes under the wings 52. 125
52, 52 and is by them directed around the
twister hooks.
The operation of the device is as fol-
