摘要： A ladder for a user to climb and which holds a rag includes a first rail having a top and a second rail and rungs attached to the first rail and second rail. The ladder includes an end cap that is attached adjacent to the top of the first rail. The end cap having an attachment portion which attaches to the first rail and a cover portion which covers over the first rail, and extends from the attachment portion. The cover portion having a rag holder. The ladder includes a pad attached to the back of the cover portion which contacts a surface against which the first rail leans down so as not to mar or scratch or damage the surface. An end cap. A method.

摘要： A method and apparatus for irrigating plant life in a manner which conserves water and optimizes soil moisture conditions. A valve is interposed between a source of water and a water outlet which is responsive to changes in soil moisture and correlative of the need for moisture in the soil. A diaphragm reciprocates between first and second positions, and the diaphragm is operatively connecting a water inlet and an outlet through a seal. The diaphragm movement is restrained by pneumatic pressure opposing the water inlet pressure. In addition, a check valve is provided whereupon a moisture sensor disposed at a terminal portion of the device directly reading moisture level in the soil allows unidirectional air flow for self-purging of the sensor.

摘要： A pump jack for a scaffold in a system to support a work platform and move the platform up and down a pole to access a vertical work surface. The pump jack includes an L-shaped framework having a horizontal frame member which supports the work platform and a vertical frame member. The vertical frame member having laterally opposing Z-shaped channels, each having a leg that bends about the pole and extends inward toward the pole. The pump jack includes an upper shackle supported by the framework. The pump jack includes a lower shackle supported by the framework, which with the upper shackle applies a coupling force for gripping the pole. The pump jack includes a pump arm lever pivotably coupled to the vertical frame member to step upwardly the pump jack relative to the pole. The pump jack includes a crank mechanism coupled to the vertical frame member. A method for supporting and moving a work platform up and down a pole to access a vertical work surface.
摘要翻译： 用于支撑工作平台的系统中的支架的泵千斤顶，并将平台上下移动到杆上以进入垂直工作表面。 泵千斤顶包括具有支撑工作平台和垂直框架构件的水平框架构件的L形框架。 垂直框架构件具有横向相对的Z形通道，每个通道具有围绕极弯曲并向着朝向极向内延伸的腿。 泵千斤顶包括由框架支撑的上部卸扣。 泵千斤顶包括由框架支撑的下卸扣，其与上钩环一起施加用于夹紧杆的联接力。 泵千斤顶包括可枢转地联接到垂直框架构件的泵臂杆，以相对于杆向上升高泵插头。 泵千斤顶包括联接到垂直框架构件的曲柄机构。 一种用于支撑和移动工作平台上下杆以访问垂直工作表面的方法。
