Apparatus for dispensing rings and for applying piston rings to pistons

Apparatus for applying rings to pistons comprising:

• a plurality of longitudinally spaced vertical tubes, each tube adapted to receive a stack of rings,
• a lip projecting from the lower end of each tube,
• means for dropping rings one at a time onto said lip,
• a ring spreader located adjacent each said lip to engage and spread open a ring,
• means to lower each said spreader into position around a piston, and
• conveyor means for advancing a series of longitudinally-spaced pistons sequentially into position under respective tubes, to receive rings one at a time.

Apparatus for applying rings to pistons comprising:

• a tube to receive a stack of rings,
• a lip projecting from the lower end of said tube,
• means for dropping rings one at a time onto said lip,
• a ring spreader located adjacent said lip to engage and spread open a ring,
• and means to lower said spreader into position around a piston located below said spreader to permit said spreader to place a ring on said piston.

Apparatus for applying rings to pistons comprising:

• a tube to receive a stack of rings,
• a fixed lip projecting from the lower end of said tube,
• a plurality of lips spaced above said first lip and slidable between retracted and projecting positions on said tube,
• means for projecting and retracting said lips,
• means for dropping said rings one at a time onto said sliding lips,
• a ring spreader located adjacent said fixed and slidable lips to engage and spread open a pair of rings resting on said fixed and slidable lips, respectively,
• and means to lower said spreader into position around a piston below said spreader to permit said spreader to place said rings on said piston.
