IMPROVED WASHING-MACHINE Specication forming part of Letters Patent No. 35,518, dated June 10, 1562.

`.To all whom it mayconcern:

' slats, or of slats and rollers, arranged in such a relation to each other that the clothes placed between the two at one side of the tub are rubbed, transferred, and pressed with a constantly-increasing pressure until `they reach the lowest point of the tub, whence they are Vcarried up the opposite side and over the rubbingcylinder, and the operation repeated as often as may be necessary by the continued rotation of the cylinder and without securing or hand- 'Ihe journals of the shaft upon which the cylinder is placed are provided with spring-bearings, that enable them to yield to any undue accumulation of clothes and to operate upon a few pieces nearly as well as upon the ordinary quantity for which the machine may have been designed.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation with reference to the drawing, which represents a perspective view of the machine.

The tub A is` formed with wooden sides and a curved zinc bottom flattened in the middle. The rollers b rotate on journals that are fitted into the bows c, placed in the angles of the sides and the bottom. The rubbing-cylinder D is composed of `t-he two heads e and the slats f,

and is carried upon the shaft g, which is fur- M l nished with a handle, h, on one of its ends.

Where the shaft passes through the sides of the tub it is sustained in bearings i, which move vertically in the slides k. The bearings are pressed down by the springs Z, the elasl ticity of which compensates for anyirregularity -in the quantity or arrangement of the mate rial subjected to the action of the machine.

` The zinc plates m cover the openings in the sides of the tub and move with the shaft g in suitable slidesattached to the inner surfaces of the sides, the joint around the shaft being protected and kept tight by a washer of indiarubber. The heads of the cylinder D are dished on the outside, that it may tilt without striking the sides of the machine. Some of the permanent slatsf of the rubbing-cylinder may be replaced by the 1 z, as is shown in the drawing; but the clothes thereby are not so readily transferred from side to side of the machine by the rotation of the cylinder. The frame and tub of the machine may be made in any convenient manner that ad mits the combination and application of the essential featuresof my invention.

When the machine is in operation, the clothes are carried around by the rotation of the rubbingcylinder and are rubbed, turned, and compressed by the conjoint action of the cylinder and the rollers as often as may be required for their thorough cleansing. The springbearings of the rubbing-cylinder occasion a uniformityof pressure and of action that obviates any necessity for special attention, causes the machine to operate with unvarying efficiency, and to complete its work with more certainty and rapidity than could otherwise be obtained. l

The formation of the tub with inclined sides and circular bottom iiattened in the middle, and the conformation of the concave Aof rollers thereto afford a gradual increase of pressure upon the clothes from their introduction until they reach the bottom of the tub.`

I claim as myinvention and desire to secure by Letters Patent- 1. The combination of the rollers b, the cylinder D, and the spring-bearings i, when constructed and arranged substantiallyin the manner described, and for the purpose specified.

2. The application of the rubbing-cylinder when constructed with fixed revolving rollers, as described, in combination with the concave of rollers b, as set forth.
