发明名称 Tool for installing and removing winterizing plugs
摘要 A tool is provided for installing and removing winterizing plugs located in drains, pools, boats, and other systems for providing protection from moisture during the winter season. Such plugs have threaded stems, and are typically secured by wingnuts. These plugs are then removed during warmer weather. In operation, the set screw is loosened to permit removal of the t-bar from the barrel. The t-bar is then inserted into a second transverse bore to serve as a handle for applying torque to selectively tighten and loosen the wingnut and to facilitate pulling the wingnut. The slotted end of the barrel is then slipped over the wingnut. Then, the wingnut can be easily tightened. This technique is also used when removing the plugs. The end of the tool is applied to a threaded portion of a winterizing plug above a wingnut for removal of the plug. The threaded portion of the winterizing plug extends well above the wingnut. The threaded portion of the passage engages the threaded portion of the winterizing plug.
