Abstract
An intermittent reversible indexing system with a rotary input and rotary output which includes a natural dwell of the output at the end of each cycle with a smooth acceleration to a maximum velocity and subsequent deceleration to another dwell and a simple mechanism for changing the index stroke. A planetary carrier carrying a single planetary gear is driven about a first axis with the planetary gear in mesh with a stationary sun gear concentric about said first axis. A drive member in the form of a shaft eccentric to the axis of said planetary engages and slides in a slot of an output member, thereby driving said output member about a second axis displaced from said first axis. A movable mount for the output member changes the drive relationship with said eccentric shaft to change the index motion.
