Discharge mechanism
Referringnow to Figs. 1 and 19. I show a dis
charge mechanism comprising a discharge plate 70
I66 provided with a pair of vertically disposed
kick-off rods I61 mounted in bearings I65 pro
vided on the cross member 21.
An arm I 69 is

to yieldably resist a downward movement of the
discharge plate. A pair of rocker arms I72 and
"3 are pivotally mounted on the cross member
bring the roller I38 around the roller I36 to form
21 and having their upper ends engaging the dis
charge plate while their lower ends .are provided
with rollers I‘M- and I75, respectively, for en
10 gagement with cams IT!‘ and H8, respectively.
The cams I11‘ and I78 are secured on the shafts
I4 and I5, respectively.
In the operation of my machine, the wire
blanks 42 are carried from their position on the
15 feed arms 4| to the form plate 26 by means of
the feed carriage 29 which is actuated by the
cam 38. The ?ngers #13, which form a V-shaped
recess on- the front of the feed carriage, serve
to, position the wire blanks against the form plate
20 where they are then formed and held against
ment of the sprocket I54 causes the chain I53
to rotate the gear sprocket IM which acts to
the hook. ’ The rollers are then returned to their
?rst position by means of the spring I30 which
is under tension; and the frame is moved to its
upper position by the cam I42.
The ?nished hanger is next discharged down
wardly from the form plate 26 by the downward 10
movement of the ?ngers I6‘! and I69 actuated by
the cams I11 and I18 through the rocking levers
I72 and I13. The springs I'II act to return these
parts to their ?rst position.
While I have shown my invention in but one 15
form it is obvious to those skilled in the art that
it is not so limited but is susceptible of various
changes and modi?cations without departing
from the spirit thereof; and I desire, therefore,
that only such limitations shall be placed there 20

The tension spring 5;»; acts to pivot the forming gers provided on the forming arms for engage
arms M5 on the return stroke of the feeding car~
riage to take up the lost motion between the
connecting links 48 and the pins 5|.
While the wire blank is being held in position
on the form plate by the forming lugs 44 and
?ngers 4'! of the forming arms 46, the shoulder
35 forming arms 56 and 57 are caused to move in
wardly by their respective cams 6'6 and BI. The
forming dies 58 and 69 act with the form plate
to form the shoulder portion 202 of the hangers.
The forward ends of the dies are provided with
positioning lugs ‘I2 and I3 and slots ‘I4 and ‘It
to accurately position the wire blank ends on
the form. plate 26 and act with the tongue 11
to bend the ends of the wire outwardly from the
form plate for the twisting operation. The form
. ing dies hold the wire blank in position on the
forming plate during the twisting operation, and
the positioning lugs are arranged to carry the
thrust of the wire ends during the twisting‘ opera
tion. As viewed in Fig. 10, the wire ends are
twisted in a clockwise direction in order that the
lugs ‘I2 and ‘I3 will prevent displacement of the
wire.
In the twisting operation to form the twist 203
in the hanger, the cam 86 acts through the push
rod 89, connecting link 92, lever 93, and shaft
8I to move the twister head 82 forward to receive
the ends of the wire blank in the slot I20. The
twister head 82 is then rotated by means of the
cam I03 which acts through the lever III'I, con
60
necting link I69, gear segment III, and pinion
gear I I3 mounted on the shaft 8I. After the ends
of the wire have been twisted together, the twist
er head is moved rearwardly by the cam 86. The
springs III and IIB serve to overcome the mo
mentum of the moving parts.
The frame I2l of the hook forming mecha
nism is next lowered to form the hook 203 of
the hanger. The frame I2I is actuated by the
cam I42 acting through a rocking lever I46 and
connecting link M8. In forming the hook, the
cam IGI acts through a rocking lever I5'I to move
the gear sprocket I54 away from the frame I2I,
thereby pulling the crank arm I26 until the stop
screw I32 strikes the stop pin I29. The axis of
75 the roller I36 is then positioned in alignment
ment with the ends of the wire blanks, and con
necting links having their inner ends pivotally
connected to the forming arms and their outerv
ends engaging the frame of the machine for ac
tuating the forming arms to bend the wire blanks
around the form plate.
