dicated in Figures 13, 15, 16 and 17, comprises a
?xed jaw'89 and a pivoted jaw ‘I8. The pivoted
jaw ‘I8 is pinned to the back end of the ?xture
89 by the pin ‘II. At the back end of the jaw'18
5 there is a curved portion ‘I2’ which projects up
wards from ,the edge ‘of the ?xture ‘as shown
clearly'in Fig. 1'7. The arm>88 of the‘ lever 84
means of the spur gears 99 carried at the ends \
of the rollers 98. These gears are shown in Fig-'
ures 4 and 5 and act to pull down the shuttle
I88 in which the paper and foil is threaded. As
indicatedin Figure 2, the spur gears 99 are op
erated by the sprocket chain I8I driven from v
the sprocket g'ear I82.
This sprocket gear de
is formed at the end in two branches ‘I3 and V rives its power originally from the gear‘ 44 which
‘I4, which are themselves forked as ‘indicated
10 clearly in Figures 13, 15 and 171 The pin ‘I5 ex
tends into this forked element ‘I3 and ‘I4 and car;
ries a ‘collar ‘I8'which ?ts over the mandrel 43.
When therefore the collar ‘I8 is forced over to
the right as indicated in Figure 15, the‘ end_‘|2
the moveable half of the mandrel is forced
15 /of
downward and the movable jaw ‘I8 of the man
drel opens upward in the positionyshown in Fig
ure 15. When therefore the spring 81 forces the
lever arm 88 to swing clockwise as viewed in the
20 position in Figure 15, the mandrel opens to re
ceive the paper and aluminum foil. When, how
ever, the portion 82 of the cam 21 comes beneath
the pin 83, the arm 88 swings counterclockwise
as viewed from the position shown in Figure 13,
25 and not only does the mandrel close and remain
closed, but also the collar moves over the man
drel and in this motion ejects the winding that
may be on it. The extreme ‘position’ indicating
this operation is shown inFlgures 1'7 and 18. The '
30 two other mentioned cams of the system com
prise the cams 25 and 28. The cam 28 controls
the mechanism for releasing the tension upon the
foiland paper when the shuttle element, about
to be explained, is raised, and applying it for
35 drawing the shuttle element downward as viewed
from the position shown in Figure 4. The cam
25 controls the cutting of the paper and foil at
the proper time as will also be explained short
- ly. The cam 28 is‘ substantially circular in shape
40' except for a small indentation ‘II. The roller ‘I8
meshes with the gear I83 driving the shaft I84.
This shaft mounted at the side. of the frame
2 is rotated in side bracket bearings I85 and I88.
~ As indicated in Figure 2, there are provided two
sprocket chains MI and 188. IM as has been
explained drives the spur 99, while the chain
I88 drives the spur gear III, which in turn drives 15
the entire, group of rollers corresponding to the
roller I I8 driven by the spur gear II I. The driv
ing of the spur gears 99, ‘H2, H3, H4, H5 and
H8 operate the pair of rollers to return they
shuttle I88 to its lowest position. - The spur gears 20
III, H8’, H1, H8, H9 and I28 are driven inter
mittently as will be explained later. Actually the
spur gears 99, H2, H3, H4, H5 and H8 are rotated
continuously,hbut only act to drive the shuttle
down when the pair of rollers are forced against 25
one another.
This action occurs when the cam
28 occupies a de?nite position as will be later
described. The shaft I84 mentioned above drives‘
continuously the spur gear I82.
As noted in Figure 1 just beyondthe bearing 30
‘I88, there is provided a spring I2I vwhich keeps
the sprocket gear I22'out of engagement with'the
shaft I84, so that the sprocket gear I22 rotates
intermittently through the clutch drive I23, This
