Abstract
Abstract A swimming pool cleaner of the random movement type having a surface transporter which rollingly engages the pool walls and a jet drive which reverses or changes direction when the transporter is stopped or slowed is provided with additional controls which as a consequence of the turning movement of the transporter against the deep end pool wall causes the transporter to travel back and forth along said deep end wall and thereby spend more time along said wall.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
In an automatic pool cleaner comprising a transporter adapted to rollingly engage pool side walls, a drive jet nozzle for the transporter having a pivotal connection therewith whereby said nozzle may drive said transporter randomly about a pool, a water supply hose connected to said nozzle, and jet driving means for the supply hose operable when said transporter is slowed along a forward line of direction to re-orient said drive jet nozzle and drive said transporter along a rearward line of direction: the provision in combination therewith of means carried by said transporter operable due to the turning of said transporter as it travels in rolling engagement with a pool side wall to slow said transporter in its direction of movement and re-orient said drive jet nozzle to drive said transporter in the opposite direction along said pool wall.
Claim 2
Dependent Claim
139 words
In an automatic pool cleaner comprising a transporter adapted to rollingly engage pool side walls, a drive jet nozzle for the transporter having a pivotal connection therewith whereby said nozzle may drive said transporter randomly about a pool, a water supply hose connected to said nozzle, and jet driving means for the supply hose operable when said transporter is slowed along a forward line of direction to re-orient said drive jet nozzle and drive said transporter along a rearward line of direction: the provision in combination therewith of means carried by said transporter operable due to the turning of said transporter as it travels in rolling engagement with a pool side wall to slow said transporter in its direction of movement and re-orient said drive jet nozzle to drive said transporter in the opposite direction along said pool wall.
Claim 3
Dependent Claim
20 words
The combination of claim 1, said last-mentioned means comprising a rudder element extending radially along the underside of said transporter.
Claim 4
Dependent Claim
47 words
The combination of claim 1, said last-mentioned means comprising a link disposed at the underside of said transporter, said link having its proximal end pivotally connected to said transporter at the central vertical axis thereof and having its distal end pivotally connected to said drive jet nozzle.
Claim 5
Dependent Claim
33 words
The combination of claim 1, said last-mentioned means comprising a swivel joint interconnecting said transporter and said drive jet nozzle, said joint being located in offset relation to said axis of said transporter.
Claim 6
Dependent Claim
116 words
An automatic pool cleaner comprising a transporter substantially circular in outline so as to engage and roll against and be rotated by a pool wall, a drive jet nozzle for the transporter having a pivotal connection therewith for random movement of the transporter about a pool, a water supply hose connected to said nozzle, said nozzle being adapted to be re-oriented to a reversing direction when the forward movement of the transporter is impeded, and means carried by said transporter operable as a consequence of the rotation of said transporter as it rolls along a pool wall to impede the forward movement along said wall of said transporter and thereby cause said nozzle to be reversed.
Claim 7
Dependent Claim
116 words
An automatic pool cleaner comprising a transporter substantially circular in outline so as to engage and roll against and be rotated by a pool wall, a drive jet nozzle for the transporter having a pivotal connection therewith for random movement of the transporter about a pool, a water supply hose connected to said nozzle, said nozzle being adapted to be re-oriented to a reversing direction when the forward movement of the transporter is impeded, and means carried by said transporter operable as a consequence of the rotation of said transporter as it rolls along a pool wall to impede the forward movement along said wall of said transporter and thereby cause said nozzle to be reversed.
Claim 8
Dependent Claim
20 words
The cleaner of claim 5, said last-mentioned means comprising a rudder element extending radially along the underside of said transporter.
Claim 9
Dependent Claim
47 words
The cleaner of claim 5, said last-mentioned means comprising a link disposed at the underside of said transporter, said link having its proximal end pivotally connected to said transporter at the central vertical axis thereof and having its distal end pivotally connected to said drive jet nozzle.
Claim 10
Dependent Claim
33 words
The cleaner of claim 5, said last-mentioned means comprising a swivel joint interconnecting said transporter and said drive jet nozzle, said joint being located in offset relation to said axis of said transporter.
