Claim 17:
18. The reciprocating device of claim 13, wherein:
during an out stroke of the reciprocating device:
the first end portion of the reciprocating shaft moves in the first direction toward the longitudinal centerline of the guide slot from a first side of the guide slot in response to movement of the at least one roller in a first longitudinal direction along the guide surface of the guide slot; and
the second end portion of the reciprocating shaft moves in the second direction toward the longitudinal centerline of the guide slot from a second side of the guide slot in response to the movement in the first longitudinal direction of the at least one roller along the guide surface of the guide slot, and

during a return stroke of the reciprocating device:
the first end portion of the reciprocating shaft moves in the second direction away from the longitudinal centerline of the guide slot from the first side of the guide slot in response to movement of the at least one roller in a second longitudinal direction along the guide surface of the guide slot; and
the second end portion of the reciprocating shaft moves in the first direction away from the longitudinal centerline of the guide slot from the second side of the guide slot in response to the movement of the at least one roller in the second longitudinal direction along the guide surface of the guide slot.
