Patent ID: 8510901

Claim:
A wringer for a mop comprising: a drive roller mounted for rotational movement and linear movement in a track; a first gear operatively connected to the drive roller for rotating the drive roller; a drive assembly comprising a first cam surface, a second cam surface and a second gear, the first cam surface engaging a first follower where the first follower is operatively connected to the drive roller such that linear movement of the first cam follower results in linear movement of the drive roller, the second cam surface engaging a second follower, the second follower being stationary, and the second gear engaging the first gear; the drive assembly being mounted for rotational movement over a range of motion such that the first cam surface, the second cam surface and the second gear rotate about a common axis where rotation of the drive assembly for a first portion of the range of motion causes the rotational movement and the linear movement of the drive roller and rotation of the drive assembly for a second portion of the range of motion causes only the rotational movement of the drive roller.
