Abstract
Abstract Apparatus for retrieving a golf ball, wherein a line is attached to the ball and a reel automatically rewinds the line to return the ball after the ball has been driven. The motor is connected with the reel through a clutch that allows the line to be unwound from the reel with a selected tension and to be rewound by the motor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A golf ball retrieving device comprising: a winding mechanism having a spool, motor means having field windings and a rotary shaft and having an armature mounted for rotation on said shaft concentric with said field windings; said winding mechanism including a disc guide secured on said rotary shaft, said winding mechanism also including a line engaging pin, means mounting said pin on said disc guide for longitudinal movement between a retracted position and a projected position relative to said disc guide; and said motor means including displacement means to displace said shaft axially in response to electric current in said field windings, and said pin mounting means including means to displace said pin toward said projected position upon concurrent rotation and axial displacement of said shaft in response to electric current in said field windings.
Claim 2
Dependent Claim
135 words
A golf ball retrieving device comprising: a winding mechanism having a spool, motor means having field windings and a rotary shaft and having an armature mounted for rotation on said shaft concentric with said field windings; said winding mechanism including a disc guide secured on said rotary shaft, said winding mechanism also including a line engaging pin, means mounting said pin on said disc guide for longitudinal movement between a retracted position and a projected position relative to said disc guide; and said motor means including displacement means to displace said shaft axially in response to electric current in said field windings, and said pin mounting means including means to displace said pin toward said projected position upon concurrent rotation and axial displacement of said shaft in response to electric current in said field windings.
Claim 3
Dependent Claim
70 words
The golf ball retrieving device according to claim 1 wherein said displacement means includes spring means biasing said shaft toward a first axial position and includes means mounting said armature axially offset from said field windings when said shaft is in said first position, and said armature being aligned axially with said field windings when said shaft is displaced axially to a second position in opposition to said spring means.
Claim 4
Dependent Claim
66 words
The golf ball retrieving device according to claim 2 including bearing means supporting said spool and said shaft for concentric rotation, said pin mounting means includes cam means fixed relative to saId bearing means, said cam means being arranged to displace said pin toward said projected position upon rotation of said disc by said shaft concurrently with axial displacement of said shaft to said second position.
Claim 5
Dependent Claim
70 words
The golf ball retrieving device according to claim 3 wherein said cam is divided between an outer portion and an intermediate portion having a cam surface supporting said pin in said retracted position and said intermediate cam having a surface maintaining said pin in a projected position, said pin being displaced from said outer cam to said intermediate cam upon axial displacement of said shaft by operation of said motor.
Claim 6
Dependent Claim
46 words
The golf ball retrieving device according to claim 1 wherein said pin displacing means includes a weight on said disc guide, said pin being secured to said weight and movable with said weight, and spring means biasing said weight towards the center of said disc guide.
Claim 7
Dependent Claim
98 words
The golf ball retrieving device according to claim 1 including case means, switch means in said case means, and guide means on said switch means for engaging a line that is wound on said spool, said winding mechanism including s substantially frusto-conical cover over said spool, said cover having a central opening through which said line extends, and wherein said guide means is aligned with said cover opening, said switch means being operable to start said motor means and to stop said motor means in response to tension in said line between said opening and said switch means.
Claim 8
Dependent Claim
83 words
The golf ball retrieving unit according to claim 6 wherein said case means includes a bottom section and a top section, said motor means and said switch means being mounted in said bottom section, said switch means includes a switch lever movable toward said cover opening to support said winding mechanism and said switch means in alignment with each other, whereby the line is pulled from said rotary spool when a golf ball attached to said line is driven along said aligned direction.
