摘要： A control device for a lift truck of the type having a drive and brake control mechanism, such as a tiller, spring loaded into either a braking or driving arc includes a support mounted on the truck adjacent the tiller and means mounted on the support for restraining the tiller upon its release from entering one of the arcs and for maintaining the mechanism within the other arc to effect the motion control determined by that other arc. In its non-braking mode, the restraining means prevents the tiller from positioning itself in the braking arc and permits the truck to coast. In its braking mode, it prevents the tiller from positioning itself in the driving arc and causes the truck to stop. The restraining means is sufficiently resilient to be overpowered by physically moving the tiller into the other arc to engage the brake (non-braking mode) or to disengage the brake (braking mode) to thereby stop or start the truck.
摘要翻译：一种用于具有驱动和制动控制机构（诸如耕作机），装载在制动或驱动电弧中的弹簧的升降叉车的控制装置包括安装在靠近耕耘机的卡车上的支架和安装在支架上的装置，用于限制耕耘机在其释放时进入其中一个弧并且用于将该机构保持在另一个弧内以实现由该另一个弧确定的运动控制。在其非制动模式中，限制装置防止耕耘机将自身定位在制动弧中，并允许卡车滑行。在制动模式下，防止耕耘机自身定位在驱动电弧中，导致卡车停止。限制装置具有足够的弹性，通过将耕耘机物理地移动到另一个弧中以接合制动器（非制动模式）或使制动器（制动模式）脱离从而停止或起动卡车而被超载。

摘要： Apparatus for depressing the accelerator of a motor vehicle and including frame means having a first portion adapted to extend downwardly from the dashboard of a vehicle and terminate at a point above the accelerator and a second portion laterally offset from the first portion and extending toward the floorboard of the vehicle. This second portion of the frame includes leg means spring biased in an extended position and adapted to contact the floorboard to urge the frame toward the dashboard and maintain the longitudinal axis of the frame oriented generally along a line extending from the dashboard to the accelerator. The device further includes means slidably mounted on the first portion of the frame means and adapted to be moved in a direction generally parallel to the longitudinal axis of the first portion of the frame means to contact the accelerator. Latch means are included to maintain the accelerator contact means in contact with the accelerator.

摘要： A means for controlling the service brakes and both engines of a dual drive train vehicle having a pair of operator stations. Each station has manually actuated brake and throttle valves capable of metering air pressure respectively to the service brakes and an engine control means. A selector valve directs air pressure to the valves in only one station and check valve means isolates the service brakes and the engine control means from the valves in the other station. An electrical circuit is provided to permit independent control of either of the two engines during starting.
摘要翻译：一种用于控制具有一对操作员站的双传动系车辆的行车制动器和两个发动机的装置。每个车站都具有手动致动的制动器和节流阀，其能够分别对运行制动器和发动机控制装置计量空气压力。一个选择阀将空气压力引导到只有一个工作站的阀门，而止回阀则意味着行车制动器和发动机控制装置与另一个车站的阀门隔离。提供一个电路以允许两个发动机在起动过程中独立控制。

摘要： A vehicle which has a transmission having forward and reverse control means in which the forward and reverse control means is connected to a bracket member on the manual control lever to shift the transmission from neutral to forward or reverse; the vehicle is further equipped with a brake mechanism actuated by a pivoted brake pedal which is connected by means of a return spring to the bracket member attached to the control lever; the spring normally tends to constantly urge the control lever in the neutral position; when in tension a lost motion connection is provided between the spring and the bracket member to allow the bracket member to be pivoted by shifting of the direction control lever without loading the spring; the mechanism functions such that, when the brake is applied, the lost motion connection is taken up and the spring is tensioned causing the direction control lever to return to neutral; the spring and the bracket member on the control lever further provides an override means permitting the tractor transmission to be shifted into forward or reverse before the brake is released by stretching the spring to obtain vehicle motion prior to complete brake release.
摘要翻译：一种具有前进和后退控制装置的变速器的车辆，其中前进和后退控制装置连接到手动控制杆上的支架构件，以将变速器从空档向前或向后移动; 车辆还配备有由枢转的制动踏板致动的制动机构，该制动踏板通过复位弹簧连接到附接到控制杆的支架构件; 弹簧通常趋向于不断地将控制杆推向中立位置; 当处于张紧状态时，在弹簧和支架构件之间设置有一个空动连接，以便通过方向控制杆的移动而使支架构件能够枢转而不加载弹簧; 机构起作用，当制动器被施加时，吸收空动连接并且弹簧被拉紧，导致方向控制杆返回中立; 控制杆上的弹簧和托架部件进一步提供一个超越装置，允许拖拉机变速器通过拉伸弹簧而释放制动器之前向前或向后移动，以在完全制动释放之前获得车辆运动。
