Abstract
805,784. Copy-turning. RETOR DEVELOPMENTS Ltd. June 9, 1955, No. 16600/55. Class 83 (3). [Also in Group XXIX] An hydraulic servomotor comprises a body 100, Fig. 2, secured to a movable member, e.g. the lathe cross-slide 14, Fig. 1, and containing first and second parallel cylinders 103, 107, a piston 104 secured to a member 16 fixed relatively to the movable member, e.g. secured to the lathe saddle 13, a control valve formed of four axially spaced discs 118-121 in the second cylinder, two passages 115, 116 respectively connecting the ends of the first cylinder to the second cylinder where they are controlled by two of the discs, a fluid inlet 108 between the two intermediate discs, two exhaust ports 110, 113 between the respective end and intermediate discs, a spring 125 urging the valve and body in opposite directions, and means whereby a control force acts against the spring to move the valve, e.g. the stylus 205 moving over template 33 and acting on the valve through the lever plate 221. By adjusting the gears 214, 215 a screw abutment 213 adjusts the relationship between the stylus and the valve. To allow the cross-slide and saddle to be positioned at will the valve is manually actuated by a knob 307 and cable 305 which rotates a cam 301 engaging the lever 221. The discs 119, 120 positively lap the ports leading to either side of the piston and have a slight clearance with the walls of the valve chamber 107 whereby pressure fluid leaks to exhaust. In another embodiment, the stylus 205 is integral with a disc having a sliding fit in the chamber 107 and abutting the valve.
