Abstract
653,180. Planing-machines. ROCKFORD MACHINE TOOL CO. March 12, 1948, No. 7570. Convention date, May 15, 1947. [Class 83 (iii)] [Also in Group XXIV] A hydraulic machine tool comprises a drive for reciprocating a work-table 28 in time with a reciprocating cutting member 24, an independent rapid-motion drive, and unidirectional means to permit the former drive to actuate gear means to drive the table during only one phase of its reciprocating cycle and to permit the rapid-motion drive to actuate said gear means during any part of said cycle without disengaging the reciprocating drive. The worktable 28 is screw-fed horizontally or vertically either by a reciprocating hydraulic piston 79, Figs. 5 and 9, acting through a reversible ratchet clutch 95, Fig. 3, or by an electric motor for fast motion. Pressure-fluid is supplied by a twin-pump 33, Fig. 9, rotated by an electric motor 34, Fig. 1. The machine is started and stopped by a manually-operated valve 45, Fig. 9. The tool-head 24 is reciprocated through lever means 39 by a hydraulic piston 37 which is reversed by a valve 75 actuated by dogs 83, 84 on the head 24. Coincidentally with reversal of the piston 37, the piston 79, which carries rack-teeth 92, is also reversed. The rack 92 meshes with a pinion 93 on a shaft 94 also carrying a gear 96 which is mounted thereon through the ratchet clutch 95 and which meshes with a gear 113 engaging a gear 114. Either of the gears 113, 114 is clutched to the vertical or horizontal feed screw by a manually-operated lever 116. The electric motor providing the rapid motion drives a shaft 121, Fig. 3, which drives the gear 96 through a ratchet clutch 118 and the ratchet clutch 95. A hand-lever 112, Fig. 1, is movable horizontally to reverse simultaneously the directions of motion transmitted by the two ratchet clutches and, at each end of its movement, it may be raised to make an electrical contact to start the rapid motion. During rapid motion the feed motion mechanism continues uninterrupted although ineffectively. The rate of feed is controlled by a screw 91 limiting the stroke of the piston 79.
