摘要： An apparatus providing means for locking the controls of construction machinery in a safe position. Implements are maintained in a preset position safe from inadvertant control activation by an operator controlled locking gate which engages the control activating linkages when they are in a neutral position. A single locking gate may be used to lock several controls and unlocking, controlled by the operator, unlocks all of the previously locked controls.

摘要： A vehicle performance sensor that monitors the operation of a vehicle and provides a shift point indicator to inform the vehicle operator when to shift the transmission. When the rotational output from the vehicle torque converter is not within the desired operating range of the transmission gearing, a signal will be generated to notify the operator by a visual indication that the transmission should be shifted and which gear should be selected.
摘要翻译：一种车辆性能传感器，其监测车辆的操作并提供换档点指示器，以通知车辆操作者什么时候改变传动。当来自车辆变矩器的旋转输出不在传动齿轮传动装置的期望的工作范围内时，将产生一个信号，以便通过视觉指示来通知操作者变速器应当被移动，哪个齿轮应被选择。

摘要： A valve for controlling the flow and pressure of fluid in a fluid operated system in which a hollow, ported control valve spool is movable in response to selective operation of a manually actuated actuator valve spool to effect modulation of a first fluid flow through the valve. One end of the hollow, ported control valve spool engages a plug portion of a freely floating piston movable in response to fluid pressure from a second fluid source to close a normally open port in the hollow control valve spool.

摘要： Apparatus for controlling steering clutches and independent brakes of a vehicle comprising a steering device responsive to a pair of clutch actuating steering levers for selectively and independently disengaging the clutches for steering purposes. Operation of a single brake pedal and the disengagement of at least one of the clutches selectively and independently engages the vehicles brakes. An inhibiting mechanism coupled to the steering device selectively inhibits either of the vehicle brakes from responding to actuation of the brake pedal when one of the steering levers is actuated to disengage the corresponding clutch, and prevents the opposite brake from being engaged during brake pedal operation. As a result, the vehicle may be steered while employing a pair of steering levers and a single foot pedal. A control system permits the vehicle to be stopped when both steering levers and the single foot pedal are actuated by inactivating the brake inhibiting mechanism.
