  • Four quadrant control lever restraint
    Patent number: 4324151
    Abstract: A control lever 10 is restrained in a neutral position through the interaction of a perforated hinged plate 24 with a horizontal rod 16 extending from said control lever 10. The hinged plate 24 is provided with a spring 44 to urge the plate into engagement with the upwardly extending end portion 20 of the rod 16 attached to the control lever 10. The hinged plate 24 is provided with a cutout 48 having a depth greater than the diameter of the control lever to prevent transverse movement of the control lever 10 when the plate 24 is in a restraining position.
