1,049,157. Manipulators. UNITED ENGINEERING & FOUNDRY CO. June 17, 1964 [July 1, 1963], No. 25980/63. Heading B3M. Manipulating apparatus for workpieces in a reversing rolling mill comprises two heads 14 and 15 which are normally situated on either side of a workpiece table 11 (Fig. 1 (in plan), not shown), the head 15 incorporating workpiece tilting fingers. The head 14 is mounted on beams 16 and 1-7 which are slidable relative to supports 21 and 22, while the head 15 is slidably adjustable on the beams 16 and 17 of head 14. The heads are each movable from their retracted position clear of table 11, Fig. 2, to an operative position (in dotted lines) by means of a rotatable pinion 32 which co-operates with a rack 33 integral with the beam 16, the beams being supported on rollers 23 and 24. The pinions for both beams are driven from a motor 35 through shafts 36. Head 15, and its supporting frame 38 and 39, is movable relative to head 14 by means of piston-cylinder assemblies 48 and 49, each assembly having an overload device for protecting the heads if an excess pressure is exerted on them. Movement of the frames 38 and 39 is synchronized by a shaft 51 connecting the pinions on two shafts 42, the pinions co-operating with racks on the beams 16 and 17. Fingers 61, Fig. 3 (not shown), arranged in vertical slots in the head 15, are raised by means of levers 63 and 64 and a piston-cylinder assembly 66 in order to tilt a workpiece. A shaft 64 operatively connects all the fingers 61 for simultaneous movement.
