Appeal No. 2006-0054
Application No. 10/007,189
longitudinal outer end of the wrench when the parts are assembled
and an opposite second inner end, said left and right parts
respectively having walls defining differently-sized, non-circular
sockets in the first outer ends thereof to be located at the
opposite longitudinal ends of the assembled parts and applied over
differently sized elements to be rotated by the wrench, said
sockets each having an end opening thereat onto the exterior of the
part involved so that the socket can be applied over and its
defining walls interlock with a selected element of corresponding
size to be rotated by said wrench and an opposite end opening onto
a first smaller driver member-receiving bore in turn opening upon a
second ball member-forming part-receiving bore, said first smaller
driver member-receiving bore having bore-defining walls adapted to
interlock with an external driver member means sized to be inserted
into the open end of the associated larger outer socket and then
moved inwardly into the associated driver member-receiving bore
where it interlocks with said left or right part involved so that
so that rotation of the driver member will rotate the wrench and
turn said element enveloped by said socket at the other end of the
assembled wrench;
a ball member-forming part adapted to be secured to and
between the said second inner ends of said left and right external
driver member means-receiving parts, the second inner ends of the
left and right parts respectively having walls defining a pair of
ball member-receiving surfaces, at least one of which forms a
ball-receiving bore; said ball member-forming part having a ball-
forming end adapted to adjustably fit in said ball-receiving bore
of one of said left and right parts and an [sic] a second end
adapted to be fixedly mounted against the ball member-receiving
surfaces of the other of said left and right parts; and
pivot-forming first and second means permitting the pivoting
of said ball-forming end of said ball member-forming part in the
ball-receiving bore involved at least in a plane which includes a
longitudinal axis extending between said outer ends of the wrench.
