Abstract: A bowling practice device (1) is described comprising a a pair of inner rail members (2,3) and a pair of outer side wall safety members (7,8). The rail members (2,3) and the side wall members (7,8) are all interchangeable with each other. A plurality of cross members (12,13,14) are provided for supporting the rail members (2,3) and side wall members (7,8) in a relatively rigid spaced relationship. In use, a rolling bowling ball is received by the forward edge (4) of the rail members (2,3) and is caused to travel along a curved surface (6) extending rearwardly and upwardly from the forward surface (4) until the ball stops. When the ball stops, it is caused to return to the bowler. The side wall members (7,8) deflect a rolling ball rolled thereagainst toward the rail members.

Abstract: A bowling practice device having a ramp with a concave upwardly sloping inclined surface and a pad located at the top of the ramp for stopping forward motion of a bowling ball and causing the ball to roll in a reverse direction down the ramp and toward a bowler. Means are also provided for supporting the ramp in a free-standing manner on a horizontal surface and for preventing movement of the ramp relative to the surface upon an impact by a ball.
