Controlled toggle mechanisms

Abstract

Abstract A MECHANISM FOR OPERATING A WORK ELEMENT FROM ONE SELECTED POSITION TO OTHER SELECTED POSITIONS IN SUCCESSION IS DESCRIBED, UTILIZING THE SPECIAL PROPERTY OF TOGGLES SO THAT THE END POSITION IS REACHED WITH SMOOTH DECELERATION AND WITHOUT OVERTRAVEL. MULTIPLE TOGGLES HAS AN INPUT END THAT IS EMBODIMENTS, WHERE EACH TOGGLE HAS AN INPUT END THAT IS ADJUSTABLE WHILE THAT TOGGLE IS BUCKLED TO CORRESPOND TO THE DESIRED POSITION THAT THE WORK ELEMENT WILL REACH WHEN A POWER ACTUATOR ERECTS THE TOGGLE. ONE TOGGLE IS USED FOR DRIVING THE WORK ELEMENT IN ONE DIRECTION AND ANOTHER TOGGLE IS USED WHEN THE WORK ELEMENT IS TO BE DRIVEN IN THE OPPOSITE DIRECTION. FOUR TOGGLES ALLOW FOR DRIVE IN EITHER DIRECTION BY ONE TOGGLE WHILE ANOTHER TOGGLE IS AVAILABLE FOR ADJUSTMENT IN CONTROLLING THE NEXT MOTION IN EITHER DIRECTION. THIS SAVES TIME, ENABLING EACH STROKE TO FOLLOW ANOTHER WITHOUT DELAY FOR ADJUSTMENTS. THE SELECTIVELY USED TOGGLES CAN BE COMPACTLY ARRANGED SIDE-BY-SIDE AT THE SAME SIDE OF A WORK SHAFT BUT CONNECTED TO OPPOSITE SIDES OF THE SHAFT, TO ROTATE THE SHAFT IN EITHER REQUIRED OPERATING DIRECTION. SIMILARLY, A COMMON ADJUSTING UNIT CAN BE USED FOR ALL THE TOGGLES, UTILIZING EXTENSIBLE AND CONTRACTABLE COUPLINGS BETWEEN THE ADJUSTING UNIT AND THE ADJUSTABLE TOGGLE ENDS.
