Abstract

1,017,845. Valves. ZAVODY PRESNEHO STROJIRENSTOI GOTHWALDOV NARODNI PODNIK. Feb. 3, 1964 [Feb. 4, 1963], No. 4472/64. Heading F2V. [Also in Divisions A3 and F1] Apparatus for controlling a bank of valves 10, Fig. 1 (not shown), which each control a piston cylinder device in a machine such as a shoemaking machine, comprises a main slide valve 16 controlling the supply and exhaust of fluid to the opposite sides of a piston (not shown), which piston is parallel to a rack 39 and connected to it by a yoke. The valve 16 is actuated by a pivoted lever 31 which acts through an extension 19 connected to the valve 16. The extension 19 also carries a pawl 34 and ratchet wheel 35. The rack 39 rotates a cam-shaft provided with cams 8 which actuate the valves 10 in the required sequence, and the rack 39 also carries pins 39<SP>1</SP> which engage the teeth of the ratchet wheel 35. In operation, the lever 31 is moved in the direction a to actuate valve 16 to move the rack to the left, the speed of movement being controlled by adjustable needle valves in the fluid supply to the actuating piston. The rack moves until one of its pins 39<SP>1</SP> engages a tooth of the sprocket wheel and in so doing, one valve 10 is actuated by a cam 8. If at this stage, the lever 31 has been released, the pin 39<SP>1</SP> moves the extension 19, valve 16 and lever 31 to the neutral position shown and the rack stops. The lever 31 may then be moved again to actuate a second valve 10. If the lever 31 is held in the actuated position, the rack 39 continues to move and the pins 39<SP>1</SP> merely rotate the ratchet wheel. The lever may be moved in direction b to reverse the sequence of operation.
