WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,506, dated April 26, 1881.

Application filed March 27, 12580. (Model) To all whom tt may concern Be it known that I, JosIAH COOPER, a citizen of the United States, and resident at Sauk Centre, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of washing-machines in which rollers are employed; and it consists in the. construction and arrangement of the several parts, hereinafter described, and pointed out in the claim.

In the drawings, Figure l is a vertical longitudinal section of a machine constructed according to my invention. Fig. 2 is a vertical cross-section of the same. Fig. 3 is avertical longitudinal section, showing the hurdle-frame,

inverted; and Fig. 4 shows the hurdle-frame.

a is the suds-box, made rectangular, and by preference is made longer than it is wide. 0n

the longer sides of the box I fix two guides, 0,

arranged to support the roller-frame, hereinafter described.

I) is a hurdle or grated frame, composed of a series of longitudinal flexible bars, I), and head-blocks W. The blocks 12 fit snugly against the end boards, a, of the suds-box, and they have their inner faces made concave, as shown, sothat they will not interfere with the movement of the rollers, hereinafter dein the side boards, 6, of the roller-frame e.

The frame 0 is made so that it sits inside the box a. The frame can be moved from end to end of the box. Therollers d are formed with the series of longitudinal radial bars or teeth d, which, in theoperation of the device, cross the bars b at right angles. The peripheries of the roller d extend below the frame 0, so that the latter will not interfere with the clothing as the said rollers are passed from end to end of the box a.

The roller-frame c is provided with handles a, by which it is moved to and fro in the sudsbox. The guides c are arranged so that they will support the roller-frame and keep the rollers from running directly on the slats b when the frame I) is in the position shown in Fig. 1.

The rollers 01, with their ribs or bars d, are at right angles to the direction of the bars I), and in the movement of the frame 0 the rollers will slightly gather the clothing between the ribs (1, while the bars I) will let the water be pressed downward out of the clothing.

In washing very delicate articles-as fine laces, &c.-the frame b is turned upside down and the box filled with water to a proper height above the upturned bars I). The bars b will have a slight elasticity, which will prevent the articles from being injured by too great pressure from the rollers d. The chamber below the bars will permit the heavier dirty water pressed out to fall to the bottom, so that it will not again be pressed through the articles, and thus the cleansing will be more perfectly done.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

In combination with the suds-box of a washing-machine, the inner removable and invertible casing, provided with a series of longitudinal flexible slats arranged with intervening spaces, and having their ends fixed on the edges of cross or head blocks, whereby, when the end or head blocks are placed in an upright position, the slats will lie flat on the bottom of the reservoir, and when the headbloeks are inverted the slats will be supported above the bottom of the reservoir and be held in proper relative position to each other, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 22d day of March, 1880.

JOSIAH COOPER.
