SAMUEL M. YOST, OF CONNERSVILLE, INDIANA.

WASHING-MACHINE.

Specicaton of Letters Patent No. 13,372, dated July 31, 1855.

To all whom t may concern.'

Be it known that I, SAMUEL IWI. Yos'r, of Connersville, in the county of Fayette and State of Indiana, have invented a new and useful Machine for Washing Clothes, Sac.; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l shows the corrugated or fluted rollers, covered with canvas, as also the crank, and the springs which impel the upper roller downward, and Fig. 2, exhibits a longitudinal section of the washing machine-frame as also of the corrugated rollers and the canvas covering.

To enable others skilled in the art to make and use this invention I will proceed to describe its construction and operation.

The frame A, Fig. 2, is rectangular with the upper side longer than the lower, and one end sloping from the upper to the lower side at one end of the machine. At 'the sloping end the clothes are introduced in the machine, the essential part of which is composed of two rollers-corrugated-b ZJ, Figs. l and 2, the one directly over the other and meshing into each other. These rollers are supported the lower one, Z1, Fig. 2, by the frame at each end so that it will revolve freely upon its axis, and the up-per roller by its axis resting upon or passing through two movable pieces, d, Figs. l and :2, of the frame, having an upward mot-ion through a. groove in each side of the frame and held down by means of springs, e, Fig. l. or similar contrivance. The rollers, b b', Fig. 2, are covered with canvas or some similar material stretched upon them, as shown o c, Fig. 1. This canvas forms almost a cylindrical surface for each roller. The rollers are so placed with respect to each other that the projection from the surface of the upper does not come in contact with the lower point or line of the concavity in the under cylinder, or roller. Consequently a hard substance, as a button, upon the material being washed, coming or passing between the rollers would not be crushed or broken. The material to be washed is placed between the rollers, the frame having received a sufficiency of water to cover the lower and about one sixth the diameter of the upper roller, and power is applied to a crank, f, Fig. l, which causes the rollers to move in a contrary direction. rThe upper roller being mostly above the surface of the water receives air between the canvas covering and the corrugated roller and, when, by action of the crank, the two rollers are in mot-ion, this air forces the water through the material being washed in such equal and perfect manner as to leave no streaks in said material, while a child can turn the crank and feed the machine, and thus accomplish as much washing and in a more thorough manner than many hands could perform in the ordinary way. The more bulky the material to be cleansed the greater the pressure in consequence of the springs which urge downward the upper roller.

What I claim as my invention and desire to secure by Letters Patent is- The arrangement of two corrugated rollers one above, and meshing into, the other without coming into contact in the lowest lines, andeach being tightly covered with canvas or other strong material, the whole combined and operating in such a manner as to eifectually washV any cloth submitted to it and without breaking the buttons or other similar hard substances upon the linen or cloth.
