Abstract
Abstract A device for imparting reciprocatory motion to a moving element by means of a driven rotor having a channel formed around the outer periphery, a channel follower driven by the rotor and an impact absorbing means acting on the channel follower to decelerate it as it completes its movement in one direction and accelerate it during its initial movement in the opposite direction.

Claim 1
Independent Claim
204 words
A device for imparting reciprocatory motion to a moving element comprising a driven rotor, a continuous channel carried by the driven rotor and formed around the outer periphery thereof, a channel follower engaging said channel and connected to the memeber to which the reciprocatory motion is imparted, one part of the channel imparting motion to the channel follower in one direction and another part of the channel imparting motion to the channel follower in the opposite direction, the two parts of the channel intersecting at an angle requiring the channel follower to change direction abruptly in passing from one part to the other, an open zone in the outer wall of the channel between the two parts thereof, and resilient impact absorbing means mounted in position to be aligned with said opening on each revolution of the driven rotor to enable the channel follower to engage the impact absorbing means through the opening at the end of the stroke of the channel follower whereby each time the channel follower passes from one part of the channel to the other the resilient impact absorbing means decelerates the channel follower as it completes its movement in one direction and accelerates its movement in the opposite direction.

149 words
A device for imparting reciprocatory motion to a moving element comprising a driven rotor, a continuous channel carried by the driven rotor and formed around the outer periphery thereof, a channel follower engaging said channel and connected to the member to which the reciprocatory motion is imparted, one part of the channel imparting motion to the channel follower in one direction and another part of the channel imparting motion to the channel follower in the opposite direction, the two parts of the channel intersecting at an angle requiring the channel follower to change direction abruptly in passing from one part to the other, and open zone in the outer wall of the channel between the two parts thereof, a tubular element connecting the channel follower and the moving element and a guide rod in telescoping engagement with an end of the tubular element to support it for reciprocatory motion.
