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.

A bowling practice device comprising:
- means forming an inclined ramp for receiving a rolling bowling ball delivered by a bowler, said ramp having a lower forward edge, a pair of spaced side edges and an upper edge and a generally upwardly sloping inclined surface extending from said lower forward edge to said upper edge, the lower half of said inclined surface being generally concave in that it is curved symmetrically upwardly from its midpoint toward each of said side edges along substantially its entire length and curved upwardly from said lower forward edge toward said upper edge with respect to at least the lower half thereof for centering a ball striking the device between said side edges;
- and
- means forming a pad at said upper edge of said inclined surface for stopping the forward motion of said ball, and causing said ball to roll in a reverse direction down said ramp toward said bowler.
