Claims6
In a ski tow having a track, an endless line, power means to move one reach of said line up a slope, a wheeled seat supported by said track, and means for connecting said seat to said line to move said seat up said slope on said track, the improvement comprising said connecting means including a first rotatable line engaging roller supported in a fixed position relative to said seat, a second rotatable line engaging roller supported on a pivot relative to said seat whereby said second roller is rotatable about its own axis and is movable through an arc about said pivot, said rollers being positioned on opposite sides of said line, manually operated lever means for moving said second roller about said pivot from a first position in which said line may move through said rollers without moving said seat to a second position in which said line is pinched between said rollers to move said seat up the slope, said manually operable lever means being inoperative to move said second roller from said second position back to said first position whereby the rider of said seat may control the engagement of said seat to said line but may not disengage said seat from said line.
In a ski tow having a track, an endless line, power means to move one reach of said line up a slope, a wheeled seat supported by said track, and means for connecting said seat to said line to move said seat up said slope on said track, the improvement comprising said connecting means including a first rotatable line engaging roller supported in a fixed position relative to said seat, a second rotatable line engaging roller supported on a pivot relative to said seat whereby said second roller is rotatable about its own axis and is movable through an arc about said pivot, said rollers being positioned on opposite sides of said line, manually operated lever means for moving said second roller about said pivot from a first position in which said line may move through said rollers without moving said seat to a second position in which said line is pinched between said rollers to move said seat up the slope, said lever means being pivotally mounted at locations spaced from said pivot, and a connecting link between said lever means and said second roller including a slot providing lost motion linkage permitting movement of said second roller toward said second position and being ineffective to move said second roller away from said second position.
In a ski tow having a track, an endless line, power means to move one reach of said line up a slope, a wheeled seat supported by said track, and means for connecting said seat to said line to move said seat up said slope on said track, the improvement comprising said connecting means including a first rotatable line engaging roller supported in a fixed position relative to said seat, a second rotatable line engaging roller supported on a pivot relative to said seat whereby said second roller is rotatable about its own axis and is movable through an arc about said pivot, said rollers being positioned on opposite sides of said line, manually operated lever means for moving said second roller about said pivot from a first position in which said line may move through said roller without moving said seat to a second position in which said line is pinched between said rollers to move said seat up the slope, an elongated support member, said second rotatable line engaging roller being rotatable supported on said elongated support member, said elongated support member being mounted on said pivot at location spaced from the axis of said second roller.
