Abstract
666,043. Planing &c. machine details. HADFIELDS, Ltd. Sept. 6, 1950 [Sept. 1, 1949], No. 22669/49. Class 83 (iii). A tool bar for a planing, shaping or slotting machine comprises a tool-holder 7 mounted in a transverse recess in the bar, means within the bar for receiving pressure fluid for moving the holder 7 to retract the cutting-edge of the tool 10 towards the body of the bar or to bring it into cutting position, and means 8 for positively positioning the holder in cutting position. In a planing-machine, the tool 10 is carried in a bar 49 and is rocked about a pivot 6 by pneumaticallyoperated plungers 19, 20. Dogs 55, Fig. 7, mounted on the reciprocating worktable and co-operating with a lever 54, reverse a table-driving motor 57 and a valve 52 controlling the plungers 19, 20, at each end of the stroke. In a slotting-machine for keyway cutting, dogs on a slide carrying the toolbar control the position of the tool. In a modified form of tool-bar, Fig. 4, the tool 32 is mounted on a piston 28 which is held in position on the cutting stroke by a rod 36 controlled pneumatically in time with the piston 28. A small communicating passage 47 delays movement of the tool until the rod 36 is withdrawn. The movements of the holder may be effected by hydraulic means.
