Title: Means for transferring stampings from a power press
IPC: B21D43/10
Filed: 1959-04-25
Abstract: 880,038. Stamping; punching; blanks transferring. SANKEY & SONS Ltd., JOSEPH, RICHARDS, H. G., and HIGGINS, A. R. April 6, 1960 [April 25, 1959], No. 14194/59. Class 83 (4). Means for transferring stampings from a power press automatically and in turn as they are produced by said press comprises a pallet 16 carried by a horizontal arm 17 which is mounted for rotation about a horizontal axis in a bearing 18 which is pivoted about a vertical axis, said arm being automatically operated and controlled so that as the press is opening it swings about said vertical axis to bring the pallet into a horizontal disposition directly below the ascending top tool 12 to receive the stamping 15 as it is ejected therefrom, and that, as the press is closing, said arm swings about said vertical axis and turns about said horizontal axis to remove the stamping clear of the press and tilt the pallet to cause the stamping to be deposited therefrom. Swinging movement of the arm 17 is effected by a cam 20, attached to the press ram 13 which co-operates with a follower 21 on the spring-loaded arm 17. The limits of the swinging movement is determined in one direction by the cam 20 and on the other by a stop pin 26 which engages the bearing 18. The automatic operation and control of the pallet arm 17 is effected by the engagement of radial pegs 27, 28 on the arm with stationary abutments 29, 30, respectively. The peg 27 determines the horizontal disposition of the arm and the peg 28, which engages the upstanding abutment 30, tilts the pallet into a vertical position whereupon a projection 31 on the pallet overlaps the upper end of a stacking rail 32 on which the stampings are collected. During the initial period of the return movement of the arm, the spring 23 turns the pallet back to its horizontal position as the peg 28 leaves the abutment 30 and the peg 27 re-engages the abutment 29 and supports the pallet in its horizontal position all the way back to its stamping-reoeiving position under the press tool. The stacking rail 32 is carried by a bracket 33 fixed to a carriage 34 adjustably mounted in a tray 36. The carriage is removed on to a platform 37 for unloading the stacking rail to enable the carriage of another collector to be placed on the tray 36.

Abstract: 469,784. Control system for poweroperated shut - off devices. BAMAGMEGUIN AKT.-GES. May 25, 1936, No. 14722. Convention date, Dec. 14, 1935. [Class 135] [Also in Group XXXVII] A control system for a series of poweractuated valves particularly those used for controlling the operation of an adsorber plant employing active carbon as adsorbing material is arranged so that following an initial controlling impulse by hand or time switch the closing movement of two valves is initiated and the control circuit broken, the circuit being automatically re-established when the two valves reach their closed position, which action initiates the opening of two other valves. In the form shown in the Figure the control is adapted to the control of the eight valves corresponding to the four phases of the active carbon process namely charging, steaming, drying, and cooling. The valves, two only of which are shown, are actuated by double-acting pistons controlled in pairs by piston control valves 7-10. These valves are successively actuated by a series of cams 13-16 on a shaft 17 intermittently rotated by an electric motor 22 acting through reduction gearing 24 and worm gearing 25. The worm-wheel may act on the shaft 17 through a crank arm and ratchet gear to ensure that the shaft is rotated exactly #th revolution at each action. The motor is connected to the power mains through two electromagnetically operated main switches 35, 47 arranged in parallel. The solenoid 36 of the switch 35 is coupled to the negative main through a push-button or time switch 37 and to the positive main through a commutator switch 26 on the shaft 17. When the pushbutton is depressed the motor is started, the circuit being maintained through an auxiliary switch in parallel with the pushbutton, actuated by the solenoid 36. After rotating the shaft through #th revolution the motor is automatically stopped leaving one or other of the cams in the position necessary to initiate the closing of two valves. When these valves reach their closed position, a series of switches arranged in series and each operated by levers coupled to the several valves are closed to complete the circuit through the solenoid 45 of the switch 47. This restarts the motor, the circuit being maintained by auxiliary contacts 46, to rotate the shaft through another #th revolution when it is again stopped leaving one or other of the cams in the position necessary to initiate the opening of a pair of valves. The valve - actuated switches also operate switches controlling indicating lamps which light up when the corresponding pair of valves are open. A further signal lamp lights up when all the valves are closed.
