摘要： A float supports a centrifugal pump driven by an internal combustion engine. A carrier handle is provided on one side of the float, and a top supporting handle permits the device to be lowered into the water on a horizontal plane with the motor running when desired. Skids extend beneath the level of the float to protect the float if the pump is dragged along the ground.

摘要： The hydrant is made so that if the exposed portion is struck by a moving vehicle or the like this portion will break off with a minimum of damage to the hydrant and vehicle. The operating mechanism provides high strength for wrenching, and protection from corrosion.
