Fuel control deceleration scheduling mechanism

Claim 1

IN A FUEL CONTROL FOR SCHEDULING DECELERATION IN A GAS TURBINE ENGINE HAVING A GAS PRODUCER WITH A COMPRESSOR AND A TURBINE TO ROTATE THE COMPRESSOR, SAID FUEL CONTROL COMPRISING: A FUEL METERING VALVE, A ROTATABLE SECTIONAL ROCKSHAFT HAVING A FIRST ROCKSHAFT SECTION, MEANS RESPONSIVE TO AT LEAST ONE PARAMETER OF ENGINE OPERATION FOR ROTATABLY POSITIONING SAID FIRST ROCKSHAFT SECTION, A SECOND ROCKSHAFT SECTION, AND CONNECTIONS BETWEEN SAID METERING VALVE AND SAID SECOND ROCKSHAFT SECTION CONTROLLING CLOSING OF SAID METERING VALVE ON ROTATIVE POSITIONING OF SAID SECOND ROCKSHAFT SECTION, A RESILIENT OVERTRAVEL CONNECTION BETWEEN SAID FIRST AND SECOND ROCKSHAFT SECTIONS NORMALLY ACTUABLE ON ROTATION OF SAID FIRST SECTION IN A VALVE CLOSING DIRECTION TO TRANSMIT ROTATION TO SAID SECOND SECTION TO CLOSE SAID METERING VALVE FOR DECELERATION OF SAID ENGINE BUT ALLOWING LIMITATION OF ROTATION OF SAID SECOND SECTION INDEPENDENT OF SAID FIRST SECTION IN A VALVE CLOSING DIRECTION, A PIVOTED DECELERATION LIMITING LEVER ADJACENT SAID SECOND ROCKSHAFT SECTION POSITIONED TO CONTACT SAID SECOND SECTION THEREBY TO LIMIT ITS ROTATION IN VALVE CLOSING DIRECTION, A MOVABLE MEMBER AXIALLY MOVABLE AS A FUNCTION OF GAS PRODUCER ROTATIVE SPEED AND CONTACTING SAID DECELERATION LIMITING LEVER LIMITING MOVEMENT THEREOF IN RELATION TO DECREASE IN SPEED OF ROTATION OF SAID GAS PRODUCER, AN ABUTMENT CARRIED BY SAID SECOND ROCKSHAFT SECTION AND RADIALLY POSITIONED FROM THE AXIS OF ROTATION OF SAID SECOND AFFORDING SPACED CONTACT WITH SAID DECELERATION LIMITING LEVER TO LIMIT CLOSING OF SAID FUEL METERING VALVE AS LIMITED BY THE DECREASE IN SPEED OF ROTATION OF SAID GAS PRODUCER, AND AN ADJUSTMENT FOR SPACING SAID ABUTMENT RELATIVE TO CONTACT WITH SAID DECELERATION LIMITING LEVER TO ALLOW LIMITED INITIAL ROTATION OF SAID SECOND ROCKSHAFT SECTION AND TO ALLOW A LIMITED CLOSING MOVEMENT OF SAID METERING VALVE PRIOR TO CONTACT WITH SAID DECELERATION LIMITING LEVER.
