Baseball bat practice device and method of manufacture

摘要

This invention concerns a baseball batting training device comprised of a weight sized for positioning in co-axial assembly with a knob of a baseball bat. The weight has an internally threaded nut secured in fixed assembly therewith. A threaded bolt bore extends through the weight and is co-axially aligned with the threaded bore defined by the internally threaded nut. A jam nut is threadingly engaged to the bolt. The bolt has external threads and is threadingly engaged through the threaded bore of the internally threaded nut. A pair of annular members are attached to the weight. The annular members are extended away from the weight in a crossed pattern and are positioned in engagement with axially facing remote surface areas of said knob of the baseball bat. The bolt when adjusted exerts a pulling force against the pair of annular members engaged against the axially facing remote surface areas of the knob to hold the baseball batting training device in fixed assembly with the knob of the baseball bat.
