摘要： A power driven socket holding ratchet wrench which has a socket made so that it has a central opening that may be used for receiving a long stud or member, which passes through the socket. The wrench acts much like a box end wrench. The wrench is made so that it can be relatively compact in axial height, that is, along the length of the sprocket and the frame is small in diameter relative to the socket size to permit it to fit into tight places. The power drive is capable of being positioned at an angle relative to the wrench head, and the wrench includes a unique ratcheting and quick release mechanism that facilitates the operation of the unit.

摘要： An electric cord reel is designed for mounting adjacent the engine of an automobile that requires a plug-in, heater, in particular, and has a power driven retract mechanism operable by an electric switch from the automotive battery or other power source, and which upon completion of retraction will shut off the retracting motor. The cord can be manually pulled out to be plugged into a receptacle at a desired location.

摘要： Disclosed is a bicycle accessory generally comprised of at least one pontoon, a frame, front bicycle mounting hardware and rear bicycle mounting hardware, and a propulsion mechanism. A common bicycle is mounted on the front bicycle and rear bicycle mounting hardware and the combination placed on water deep enough to enable floatation of the watercraft, a bicycle and a rider thereupon. A rider climbs propels and directs the watercraft in the manner customary for bicycles on land.
