Abstract: Apparatus embodying the invention includes first and second motors coupled to a carriage assembly for moving the carriage assembly back and forth between first and second end points. The first motor is for developing a force to drive the carriage in one direction and the second motor is for developing a force to drive the carriage in an opposite, second direction. When the first motor causes the movement of the carriage in one direction, the slowing, stopping and reversal of the carriage is achieved by varying the power supplied to the second motor relative to the power supplied to the first motor until the force exerted by the second motor first equals and then exceeds the force exerted by the second motor. So operated, the carriage motion is well controlled and exhibits little, if any, backlash.

Abstract: A hydrostatic guidance system for a moving carriage upon a lathe bed or other such machining has a plurality of fluid, preferably air bearings mounted on the carriage and a pressurized fluid manifold device for routing the pressurized fluid to the air bearings. The several air bearings are located and oriented on the carriage adjacent the rails or ways of the machine so that the carriage is made to float, contact free, over the ways for smooth, jerk free movement. At least one of the air bearings is mounted on the distal end of a bendable beam which, under pressure of the air, maintains the gap between the bearing and the way despite variations in the straightness or linearity of the way so as to maintain a uniform velocity profile.
