Abstract

A fastener removal apparatus is configured for removing a nut from a threaded shank and includes a gearbox assembly, an outer socket, and a tubular sleeve member. The gearbox assembly has an input member, a first output member, a second output member, and a plurality of gears. The first output member and the second output member rotation in opposite directions about a longitudinal axis in response to rotation imparted to the input member. The outer socket extends between a first end defining a female polygonal opening and a second end engaged for concurrent rotation with the first output member. The tubular sleeve member extends between a first end defining a threaded opening for receiving threads defined by the threaded shank and a second end engaged for concurrent rotation with the second output member.

Dependent claims

A fastener removal apparatus configured for removing a nut from a threaded shank and comprising:

a gearbox assembly having an input member, a first output member, a second output member, and a plurality of gears disposed between said input member and said first output member such that said first output member and said second output member rotation in opposite directions about a longitudinal axis in response to rotation imparted to said input member;
an outer socket extending along and centered on said longitudinal axis between a first end defining a female polygonal opening for mating with the fastening nut and a second end spaced from the first end along said longitudinal axis and engaged for concurrent rotation with said first output member;
and
a tubular sleeve member surrounded by said outer socket, said tubular sleeve member extending along and centered on said longitudinal axis between a first end defining a threaded opening for receiving threads defined by the threaded shank and a second end spaced from the first end along said longitudinal axis and engaged for concurrent rotation with said second output member.
