Independent Claim
181 words
A ball tossing training device comprising: a self-supporting stand; a ball receiver mounted on said stand above ground level; an angularly adjustable ball track feeder for receiving balls from said receiver, said track feeder having a loading end and a discharge end; means for adjusting the inclination of said ball track feeder to control the speed of a ball moving therealong; means for intermittently automatically feeding a single ball at a time along said track feeder; ball tossing means positioned below said discharge end of said track feeder for deflecting each ball discharged therfrom; and a self-supporting stand including a telescopic rod comprised of an upper portion and a lower portion, said ball receiver and said ball track feeder being attached to said upper portion, and a spring attached at one end to said upper portion and at its opposite end to said lower portion whereby said upper portion may be telescoped down into said lower portion to lower said ball receiver and said ball track feeder and, upon release, the upper portion will spring back to its normal upper position.

A device according to claim 1, wherein said means for intermittingly feeding a ball includes a pivotable ball holder for receiving a ball discharged from said track feeder and a first ball stopper operatively associated with said ball holder whereby when said ball holder receives a ball, the ball holder pivots downwardly and causes said first ball stopper to move to a ball releasing position.
Claim 4
Dependent Claim
67 words
A device according to claim 2, wherein said means for intermittingly feeding a ball further includes a second ball stopper operatively associated with said first ball stopper whereby movement of said first ball stopper to a ball releasing position to release a first ball causes said second ball stopper to move to a ball retaining position to retain a second ball from movement along said track feeder.
Claim 5
Dependent Claim
33 words
A device according to claim 1, which includes a guide tube between said ball holder and said ball tossing means for directing a ball from said ball holder to said ball tossing means.
