Abstract: The invention provides an easily adjustable foot-operated pedal assembly, such as a brake pedal for use in heavy equipment, that can be placed in multiple positions to accommodate people of differing heights and body shapes. The pedal is mounted in an assembly including a dual linkage operating apparatus having one element of that linkage that freely rotates about a shaft. A second link of the pedal linkage is connected to a fixed link through an adjustment mechanism. The fixed link is fixedly mounted to the same shaft as the pedal link. The adjustment mechanism incorporates a latch that has multiple settings yielding three or more pedal positions. The pedal is urged upwardly to effect adjustment to raise the pedal. A latch bar of the pedal assembly is urged up to allow lowering of the pedal.

Abstract: A braking system controlled by an operator's pedal for a vehicle equipped with a mechanically actuated brake clutch pack in which a cam is rotated in response to movement of a brake pedal to operate a pressure-modulating hydraulic valve to direct fluid pressure to an hydraulic actuator extendable under pressure to engage a force transfer member secured to an actuator rod, which rod is connected to apply the clutch pack when tensioned.

Abstract: A flush mounted hinge assembly for pivotally mounting a heavy closure on an armored vehicle such that the closure is disposed within an opening in the vehicle hull and is pivotal at least 180.degree. to an open position comprises two pairs of first and second hinge plates pivotally connected to intermediate hinge members so as to enable the first and second hinge plates to pivot about substantially parallel axes with respect to the intermediate hinge members. The hinge plates are disposed within recesses in the exterior surfaces of the closure and the hull, and the intermediate hinge members are mounted on an outwardly facing surface of a floating link member which extends between the intermediate hinge members and which constrains the intermediate hinge members for concerted movement.
