Abstract
Abstract A soccer ball practice machine includes a pair of juxtaposed, oppositely rotating wheels for propelling a soccer ball toward a soccer player to facilitate the practice and instruction of a wide variety of soccer skills. The orientation of these wheels can be selectively varied to permit the soccer ball to be propelled in an infinite number of directions. In addition, the distance separating the rotating juxtaposed wheels can also be adjusted to accommodate soccer balls of varying diameters and can be automatically increased to prevent damage to oversized balls due to engagement by the wheels. A large hopper includes a rotating auger which successively feeds soccer balls in the hopper into a flexible feed tube and down a rigid ball chute where they are engaged by the wheels and propelled outwardly. The flexibility of the feed tube and the rigidity of the ball chute provide accurate delivery of the balls to the wheels and confinement of the balls on all sides as they are engaged and propelled by the wheels, even though the positions of the wheels relative to the hopper may be changed to vary the direction of the ball's flight.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
A soccer ball practice machine, comprising: a pair of rotating wheels separated by a distance sufficient to engage a soccer ball between them and propel it toward a soccer player to facilitate the practice of soccer skills; a hopper for containing a large number of said soccer balls; guide means for conducting said soccer balls in said hopper from said hopper to said wheels; and a pair of mounting members for individually mounting said wheels, said mounting members being rotatably mounted to provide means for selectively increasing or decreasing said distance between said wheels to accommodate soccer balls of various diameters; a rod between said mounting members to provide means for adjusting the rotational position of said mounting members so that said wheels are separated by a distance sufficient to engage and propel said soccer balls of various diameters; and tension means on said rod for (i) permitting said mounting members to spread apart in response to a larger soccer ball to increase said distance between said wheels by an amount sufficient to propel said larger soccer ball without damaging it, and (ii) automatically restoring said mounting members to their original position after said larger soccer ball has been propelled.
Claim 2
Dependent Claim
200 words
A soccer ball practice machine, comprising: a pair of rotating wheels separated by a distance sufficient to engage a soccer ball between them and propel it toward a soccer player to facilitate the practice of soccer skills; a hopper for containing a large number of said soccer balls; guide means for conducting said soccer balls in said hopper from said hopper to said wheels; and a pair of mounting members for individually mounting said wheels, said mounting members being rotatably mounted to provide means for selectively increasing or decreasing said distance between said wheels to accommodate soccer balls of various diameters; a rod between said mounting members to provide means for adjusting the rotational position of said mounting members so that said wheels are separated by a distance sufficient to engage and propel said soccer balls of various diameters; and tension means on said rod for (i) permitting said mounting members to spread apart in response to a larger soccer ball to increase said distance between said wheels by an amount sufficient to propel said larger soccer ball without damaging it, and (ii) automatically restoring said mounting members to their original position after said larger soccer ball has been propelled.
Claim 3
Dependent Claim
24 words
The soccer ball practice machine of claim 1 wherein said tension means comprises springs mounted on said rod and bearing against said mounting members.
Claim 4
Dependent Claim
221 words
A soccer ball practice machine comprising: a pair of rotating wheels for propelling a soccer ball toward a soccer player to facilitate the practice of soccer skills; first mounting means for mounting said wheels; said first mounting means being pivotally mounted about generally a vertical axis and limited to less than 360° rotation and which first mounting means is mounted on a pivoted frame that pivots about a substantially horizontal axis, said wheels and said first mounting means being pivoted together when said frame is pivoted; second mounting means for rotatively mounting said first mounting means about a horizontal axis, said second mounting means also being rotatable about a horizontal axis, the relative positions of said first and second mounting means being independently adjustable with respect to one another to vary the orientation of said wheels and the direction of said soccer ball as it is propelled toward said player, the axis of said second mounting means being provided with wheels to make said practice machine trailerable behind a vehicle to provide means for facilitating transportation of said machine; a hopper containing many of said soccer balls, said hopper being mounted on said second mounting means; and means for conducting said soccer balls in said hopper to said wheels regardless of the relative positions of said first and second mounting means.
Claim 5
Dependent Claim
221 words
A soccer ball practice machine comprising: a pair of rotating wheels for propelling a soccer ball toward a soccer player to facilitate the practice of soccer skills; first mounting means for mounting said wheels; said first mounting means being pivotally mounted about generally a vertical axis and limited to less than 360° rotation and which first mounting means is mounted on a pivoted frame that pivots about a substantially horizontal axis, said wheels and said first mounting means being pivoted together when said frame is pivoted; second mounting means for rotatively mounting said first mounting means about a horizontal axis, said second mounting means also being rotatable about a horizontal axis, the relative positions of said first and second mounting means being independently adjustable with respect to one another to vary the orientation of said wheels and the direction of said soccer ball as it is propelled toward said player, the axis of said second mounting means being provided with wheels to make said practice machine trailerable behind a vehicle to provide means for facilitating transportation of said machine; a hopper containing many of said soccer balls, said hopper being mounted on said second mounting means; and means for conducting said soccer balls in said hopper to said wheels regardless of the relative positions of said first and second mounting means.
