Abstract
A cut-off machine especially suitable for handling tubing and including a machine frame defining a work treatment area, a ram on the frame adjacent the work treatment area mounted for movement through a power stroke by at least two drive members engaging the ram at spaced points, a motor system mounted on the frame, and a drive system interconnecting the motor system and the drive members on the ram. The drive system comprises a pair of flywheels driven by the motor system, a pair of crank shafts driven by the flywheels through a clutch associated with each flywheel, and a crank portion on each crank shaft journalled in the ram so that the ram is moved through an orbital path in response to rotation of the crank shafts. A gear train is positioned between the crank shafts to synchronize the rotation of the crank shafts to ensure that the ram moves in a translatory manner through its orbital path.
