Patent ID: 7632045

Claim:
A mixing attachment for use in mixing resin used in the securement of an anchor bolt in a bore hole, the mixing attachment comprising, a body extending longitudinally along an axis from a first end portion to a second end portion, and including, at least one blade member, including at least one associated mixing face extending generally radially relative to said axis, said mixing face configured to assist in mixing said resin as said mixing attachment is rotated about said axis, a recess formed in said second end portion sized for complementary mated engagement with a distal end of said anchor bolt, said recess configured to couple said mixing attachment to said distal end with a minimum contact force selected so that prior to the setting of said resin, the rotation of the anchor bolt in said bore hole effects rotation of said mixing attachment about said axis, while permitting relative axial movement between said body and said anchor bolt upon the application of a predetermined minimum yield force, so as not to substantially interfere with yielding axial movement of the anchor bolt in said bore hole.
