Filed:
Sep 23, 1974
Appl. No.:
5/502456
Inventors:
Daniel F. Greaney - West Roxbury MA
International Classification:
A63B 6940
US Classification:
273 26B
Abstract:
A practice sleeve used in connection with baseball and similar bats which prevents a ball struck by the bat from going any significant distance and improves the users swing. The sleeve is fabricated from a single sheet of rectangular plastic material having a pair of concentric notches cut into one surface the entire length of the plastic sheet. These notches are spaced approximately 1/2 inch apart and are spaced an equal distance from the longitudinal center line of the sheet. The plastic is then folded about the notches to form a substantially V-shaped troughed sleeve having a 1/2 inch blunted ball hitting surface. The sleeve is then provided with shock cords, transversly attached thereto, for holding the sleeve on a bat.
