  • Patent number: 4920877
    Abstract: An improved wringer device is provided for squeezing water from a cloth or chamois when fed between a pair of adjacent rollers. Each roller is made from thermoformed plastic, or molded elastomeric material with an outer surface defining a plurality of axially alligned curvilinear hill and valley surfaces. The hill surface of one roller meshes with a valley surface of the adjacent roller to assist in feeding the cloth through the rollers and to maximize efficiency by minimizing required cranking force. The device includes a first support member for mounting to a wall, a second roller support member pivotably connected to the first member, and a third roller support member fixedly secured to the second member, a pair of rollers with substantially parallel axes and each supported between the second and third support members, and a crank interconnected with one of the rollers to drive that roller, which then drives the other roller.
    Type: Grant
