Abstract:
A clutch arrangement for a multiple spindle machine operable at a low speed or a high speed and having a timing shaft, the clutch arrangement comprising:a starting clutch in generally surrounding relation with a starting clutch drive shaft, the starting clutch being selectively operative to cause rotation of the starting clutch drive shaft, wherein when the starting clutch is engaged the multiple spindle machine is operable at the low speed;a machine brake clutch in generally surrounding relation with the starting clutch drive shafts and spaced longitudinally from the starting clutch, the machine brake clutch being selectively operative to slow the rotation of the starting clutch drive shaft, and wherein when the starting clutch is disengaged the machine brake clutch is selectively engaeable to cause the rotational speed of the starting clutch drive shaft to slow;a high speed clutch in generally surrounding relation with a long worm drive shaft, the high speed clutch being in selectively operable connection with the starting clutch drive shaft and selectively operative to cause rotation of the long worm drive shaft, wherein when the high speed clutch is engaged the multiple spindle machine operates at the high speed; anda snubbing clutch in generally surrounding relation with the long worm drive shaft and spaced longitudinally from the high speed clutch, the snubbing clutch being selectively operative to slow the rotation of the long worm drive shaft, wherein when the high speed clutch is disengaged the snubbing clutch is selectively engageable to cause the rotational speed of the worm drive shaft to slow.
