When the shaft 331 is moved in one direction
of rotation, the pin 329 will lift the shifting col
lar 325 which carries a sliding key 339 upwardly
into the path of the adjacent blunt end of the
wound spring clutch 3| i. This causes one blunt
end of the wound spring to engage the shoulder
provided by reason of the helical surface on the
face of the gear 3|5 while the other blunt end en
gages the key 339. This key rides in a slot pro
vided for it in the sleeve 309 to provide a driving>
connection between the shaft 395 and the bevel“V
gear 3|5 which drives the crown gear 3|9 of the
roll shaft 323. The wound spring 3| I in this case
expands against the inner wall of the sleeve 303.
The sleeve 309 is provided with apertures 34| to
permit the escape of lubricant from the portion
of the sleeve occupied by the wound springs so
that a satisfactory grip will be provided between
the wound spring and the sleeve 339. The key’
339 is moved downwardly when the shaft 331 is
moved in the opposite direction to engage the end
of the wound spring to cause driving engagement

gage either of the projections 363 or 355 to move
the shaft 33| and the collar 325 to the neutral
position which will stop the driving of the wringer
rolls.
An index mechanism with an interlock is also
provided. For this purpose, the supporting post
is provided with a flange 31| containing aper
tures. These apertures are of suitable size to re
ceive the index latching pin 313, This latching
`pin is slidably mounted in the wringer support
and pressed downwardly by the compression
spring 315. An index release lever 311 is provided
for raising the index latching pin 313. The outer
end of this index release lever 31".' is provided with
a knob 319 and also extends through an aperture
in the lower end of a vertical sliding member 38|
having slots 333 and 335 which allows the mein
ber 38| to move vertically. The upper end of the
member 38| is bent 180° and provided with a pair
of humps 381.
'
The shaftl 33| is provided with a set of hori
zontal projections 389, one of which will be moved
just out of contact with one of the humps 381
