    • A cam-lock water gate designed to control water flow from a pond, lake, field, canal or the like. A primary body member is provided with an aperture therethrough and a short section of pipe stub integral with the main body member and opening into said aperture. An adjustable gate plate is mounted on said main body member and constrained between parallel guide channels to permit the gate to be adjusted for completely opening the aperture, partially opening the aperture, or completely closing the aperture. A regular duty embodiment employs a simple handle and rod control for both adjusting the gate plate as well as locking the cam-lock mechanism to positively retain the gate plate in the set position once adjusted. Another heavy duty embodiment employs heavier materials and heavier construction of the device and also incorporates a security lock bar that enables the gate plate to be locked to prevent unauthorized adjustment thereof. Another embodiment employs a threaded rod with adjusting nut operated by a wheel type control. A modified cam-lock mechanism is also incorporated for locking the gate plate in adjusted position. Rustproof and corrosion resistant materials are used for construction throughout all of the embodiments. Because of the lightweight construction employed all of the devices may be installed without the use of heavy equipment for most installations.
    • 设计用于控制来自池塘,湖泊,田野,运河等的水流的凸轮锁水门。 主体构件设置有穿过其中的孔,以及与主体构件一体并且通向所述孔的短管段。 可调门板安装在所述主体构件上并且限制在平行导向通道之间,以允许调节门以完全打开孔,部分地打开孔或完全闭合孔。 正常工作实施例采用简单的手柄和杆控制来调节门板以及锁定凸轮锁定机构,一旦调整就将门板牢固地保持在设定位置。 另一个重型实施例采用较重的材料和较重的装置结构,并且还包括一个安全锁杆,其能够锁定门板以防止其未经授权的调整。 另一实施例采用具有由轮型控制器操作的调节螺母的螺纹杆。 还结合了改进的凸轮锁定机构,用于将门板锁定在调节位置。 在所有实施例中,防锈和耐腐蚀材料用于施工。 由于所采用的轻质结构,所有的设备都可以安装在大多数安装的情况下,不需要使用重型设备。

    • A contact safety and trigger mechanism for use with a pneumatic fastener in order to permit efficient pneumatic fastener actuation mode selection. A rotating rod is included in a contact safety assembly which is constructed to slide toward/away from a driver housing, defining a piston for securing a fastener disposed within the piston's path of travel. The rotating rod includes a first shoulder or ledge and a second shoulder which is off-set from the first shoulder. The rod may be rotated in order to orientate the selected shoulder, to function as a stop for a pivoting trigger assembly, which is constructed to contact a pneumatic valve, to initiate a fastening event in-which a fastener is driven into a workpiece. The configuration of the rotating rod permits for selection between a contact actuation mode wherein movement of the contact safety initiates securing of a fastener and a sequential actuation mode in which the trigger assembly is manipulated by a user to trigger securing of a fastener after the contact safety has be depressed towards the driver housing.
    • 一种用于气动紧固件的接触安全和触发机构,以便允许有效的气动紧固件致动模式选择。 旋转杆包括在接触安全组件中,其被构造成朝向/远离驱动器壳体滑动,限定用于固定设置在活塞行进路径内的紧固件的活塞。 旋转杆包括第一肩部或凸缘以及从第一肩部偏离的第二肩部。 杆可以旋转以便使所选择的肩部定向,用作用于枢转扳机组件的止动件,枢转扳机组件被构造成接触气动阀,以启动紧固件,紧固件被驱动到工件中。 旋转杆的构造允许在接触致动模式之间进行选择,其中接触安全性的移动开始固定紧固件和顺序致动模式,其中触发器组件由用户操纵以触发紧固件在接触安全性之后的固定 已被迫向驾驶者住房沮丧。
