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. Each support member is preferably fabricated from injection molded plastic, and may be structurally identical to reduce tooling and manufacturing costs.
