Abstract
A hand tool for removing a wheel valve handle and tightening a valve packing nut. A wrench member detachably carries nut receiving sockets at its lower end. Arms at the lower end of a tubular member engage and retain the valve handle during handle removal and replacement. The tubular member is equipped with an impact slide member for facilitating handle removal. A spring member biases the arms and a valve handle thereon upwardly against a socket in place on the wrench member of the tool.
Claims11
A tool for servicing remotely disposed handle equipped valves having a packing nut, said tool comprising,
- an elongate wrench member including a shaft adapted at its lower end for engagement with a valve nut securing the valve handle, and
- a tubular member movably mounted on said wrench member and including valve handle engagement and retention means at one end for inserted engagement with the valve handle, said tubular member including an impact surface against which upwardly directed forces may be imparted during handle removal from the valve.
A tool for servicing in a remote manner handle equipped valves located below ground level and of the type having both a handle secured by a nut and a packing nut located adjacent the valve handle, said tool comprising,
- an elongate wrench member adapted at one end for engagement with a valve nut,
- a tubular member slidably disposed on said elongate wrench member and including end mounted valve handle engagement and retention means, and
- resilient means urging said tubular member in an axial direction to bias a valve handle temporarily in engagement with said handle engagement and retention means toward said one end of said wrench member whereby the valve handle may be removed from the valve being serviced.
