ABSTRACT:
An extended ratchet designed to readily obtain access for tightening or loosening nuts or bolts located within tight or "hard to get at" places with the shaft of the ratchet being turned in the same axis as the ratchet handle rather than a side to side motion, the top turn ratchet consisting of a cylindrical and hollow handle through which is assembled a round shaft with provisions on one end for turning the shaft by means of a T-type handle, by an open end or crescent wrench, or by a conventional ratchet wrench, and with the shaft being affixed on its opposite or driving end with a beveled gear interconnected to a second beveled gear to transfer the drive force in a direction perpendicular to the axis of the drive shaft. The beveled gears are contained within a housing which is provided with openings for access to the beveled gears for purposes of assembly of the beveled gears therein and for maintenance of said gears, with the openings being round and threaded for the easy attachment or removal of round protective covers over said openings. The top ratchet can also be used to obtain access within tight areas for the assembly or removal of bolts or nuts from either end of the ratchet.
