ABSTRACT:
A drain plug removing device including a removable socket located at the head of the device, which socket is adapted to securedly engage and hold the head of a threaded drain plug. The socket is fixedly coupled to the upper external member of a retaining socket holder, the lower section of which is disposed within a cavity of the device head in fixed engagement with a crown gear adapted for rotation within the cavity. A pinion gear is movably coupled within the head cavity to the crown gear. A tubular housing having a chamber in communication with the head cavity is fixedly connected to the device head. A drive shaft disposed within, and extending throughout the length of, the chamber is fixedly coupled at one of its ends to the pinion gear. At its other end, the drive shaft is fixedly coupled to a rotatable external handle positioned adjacent the end of the housing opposite the device head, whereby rotation of the handle is translated through the drive shaft and the gears to produce a simultaneous rotation of the socket holder, the socket and a drain plug engaged therein. Oil drain ports are included in the device head to allow excess oil to drain therefrom, and the invention may also include a separate portable receptacle into which the device head is placed to receive the excess oil that drains from the device head through its drain ports.
