摘要： A hand-operated control assembly for accomplishing both transmission gear selection and engine speed control through a single control member or lever, gear selection being accomplished by pivotal movement of the lever and engine speed regulation being accomplished by rotation of the lever about its own axis. With the control lever being preferably movable in a conventional U-shaped pattern for gear selection, a relatively simple and novel interconnection is provided for coupling the single control lever with a transmission control selector rod and an engine speed control rod.

摘要： First and second handles are movably mounted on a stationary support. The first handle is connected to the control elements of first and second control valves whereas the second handle is connected to the control element of a third control valve. Movement of the first handle in a first direction will reciprocate the first control element whereas movement of the second handle in such direction is non-functional. Movement of the first and second handles in the second, transverse direction will simultaneously reciprocate the second and third elements, respectively. A pivoted latch selectively locks the two handles in their neutral conditions of operation and the second handle is frictionally held in a selected position by a pair of rubber bushings.
摘要翻译：第一和第二把手可移动地安装在固定支架上。第一手柄连接到第一和第二控制阀的控制元件，而第二把手连接到第三控制阀的控制元件。第一手柄沿第一方向的移动将使第一控制元件往复运动，而第二手柄在该方向上的移动是不起作用的。第一和第二手柄在第二横向方向上的运动将分别同时往复运动第二和第三元件。枢转闩锁选择性地将两个手柄锁定在其中性操作状态中，并且第二手柄通过一对橡胶衬套摩擦保持在选定位置。

摘要： An electromagnetic bucket positioner includes an electromagnet disposed to selectively latch, when energized, a control valve of a bucket positioning system. A normally-open switch is included in the system, and is adapted for closure via selected movement of a manually operable control lever, thereby energizing the electromagnet to latch the control lever in the select position. A normally-closed switch is disposed in series with the normallyopen switch, and is adapted to be opened upon selected translation of the cylinder rod of the associated hydraulic cylinder, to thus interrupt current flow to the electromagnet, to de-energize same and release the control lever. The control valve returns to a neutral position, stopping the flow of hydraulic fluid to the respective cylinder, to stop further movement, tilt, etc., of the vehicle bucket. An electronic relay circuit may be included to introduce current to the electromagnet when energized via closure of the switches. In the latter embodiment, the relay circuit is de-energized after the electrical circuit is interrupted by opening the respective normally-closed switch.
摘要翻译：电磁斗定位器包括电磁铁，其设置成当通电时选择性地锁定铲斗定位系统的控制阀。常开开关包括在系统中，并且适于通过手动操作的控制杆的选择的运动来关闭，由此激励电磁体以将控制杆锁定在选择位置。常闭开关与常开开关串联布置，并且适于在相关联的液压缸的气缸杆的选定平移时打开，从而中断电流到电磁体的电流，以使其断电，并且释放控制杆。控制阀回到中立位置，停止液压流体流向相应气缸，停止车辆桶的进一步运动，倾斜等。可以包括电子继电器电路以在通过闭合开关通电时将电流引入电磁体。在后一实施例中，通过打开相应的常闭开关中断电路后，继电器电路断电。

摘要： A single lever control comprises a tubular bellcrank pivotally mounted on a stationary support and a handle pivotally mounted to a first arm of the bellcrank. A connecting rod is universally connected to the handle and extends through the bellcrank for attachment to the stem of a first control valve. A second arm of the bellcrank is pivotally connected to the stem of a second control valve whereby the handle may be actuated to selectively actuate the first control valve and/or the second control valve.
