  • Patent number: 5916276
    Abstract: A wringing device is provided including a housing with a top face, a bottom face, a front face, a rear face and a pair of side faces formed therebetween thus defining an interior space. The top face has an entry opening formed therein and the front face has an exit opening formed therein. A roller assembly is situated within the housing. A drive mechanism is also positioned within the housing and remains in communication with the roller assembly for wringing a piece of cloth when put in the entry opening, whereafter the piece of cloth is dispensed from the exit opening.

  • Patent number: 5349720
    Abstract: A mop wringer which includes a combination of a pail and lid wherein the lid can be locked to the pail. A first roller is mounted for rotation about a first axis in the lid while the lid includes an opening and a lid panel is hinged to the lid within the opening. The hinged panel rotates about a hinged axis parallel to the first axis and a second roller is mounted to the hinged panel in an area of the hinged panel remote from the second hinged axis and where the second roller is adjacent the first roller and forms a nip therebetween. Spring means extend between the lid and the hinged panel to urge the hinged panel towards a closed position with the first and second rollers adjacent each other, but the hinged panel can be pressed downwardly to provide access through the opening for a mop.

  • Patent number: 4889049
    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 aligned 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 selectably 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.

  • Patent number: 4554806
    Abstract: A motor driven wringer unit for use in combination with a counter and sink of the type commonly found in a household kitchen. A motor driven wringer has a frame with a pair of rollers rotatably attached thereto and a motor for rotating one of the rollers whereby a cloth or sponge will pass between the rollers and squeeze the liquid out of such wet cloth or sponge to achieve a predesired dampness in such cloth or sponge. A liquid catching arrangement is provided for catching liquid extracted from the cloth or sponge and a spout is provided for directing such liquid back into a sink or the like. A base is provided for the aforementioned apparatus whereby the motor driven wringer unit can be placed on a counter adjacent to a sink wherein the spout means will direct the liquid extracted from the cloth or sponge into the sink. A safety mechanism is also provided on the wringer apparatus for automatically turning off the rollers when the user's hand is in danger of being caught between the rollers.

  • Patent number: 4452135
    Abstract: A fire hose retracting and flattening apparatus has a first endless belt having a width at least as great as that of the hose to be retracted which is mounted in a main frame so as to have a generally planar run thereof on which the hose can be lain. The belt is mounted so as to be operatively connected to a motor to effect the driving thereof in a retracting direction. First and second pairs of rollers are provided which co-act with the planar run of the belt to retract and flatten the hose disposed thereon. The first and second roller pairs are mounted above the planar run, with the first roller pair downstream of the second roller pair, for pivotal movement between a first position wherein the first roller pair is adjacent to the run and the second roller pair is spaced apart therefrom and a second position wherein the first roller pair is spaced apart from the run and the second roller means is adjacent thereto.
