Abstract
343,718. Hydraulically - operated machine tools. CHURCHILL MACHINE TOOL CO., Ltd., Broadheath, near Manchester, and ASBRIDGE, H. H., Claremont, Washway Road, Ashton-on-Mersey. Feb. 5, 1930, No. 3876. [Class 60.] Driving and feed devices.-In a machine tool, for example, a machine for grinding crank shafts, the table b carrying the work e is moved from one grinding position to the next, as determined by a stop 5 and a notched bar 7 on the table, by a piston g moving under hydraulic pressure in a cylinder h, the motion being slowed down as the table approaches its desired position. The movement of the table is controlled by a valve n in a casing k and actuated, through a link 23, by a handle m, the exhaust pipe t leading to a spring-closed valve v in a casing u. The valve v is depressed, to open it, by an arm y on a shaft z connected to a plate 2 pressed upwardly by a spring 3 to engage the stop 5, which is slidable in a slide 8, and may be moved by a handle 9; the slide 8 may be adjusted relatively to the bed a, thus giving a fine adjustment to the table b, by a screw operated by a handle 13. The table is moved by depression of the stop 5 by the handle 9 and actuation of the valve n, the handle 9 then being released, so that, as the stop rises, the valve v is closed gradually, thus throttling the exhaust and slowing down the table. In order to prevent actuation of the table b whilst the grinding- wheel f is in the operative position, a handle 21 controlling the movement of the grinding-wheel is provided with a bar 20 having an enlarged end and resting on a pin 24, a stem 18 being supported on the bar and having at its top a V-block 17 with which engages a roller 22 on the handle m. The block 17 holds the handle m to position the valve n in neutral position when the handle 21 is in position to locate the grinding-wheel in the operative position, so that the valve n cannot be operated to move the table b. The valve v has therein a small byepass opening 25.
