IMPROVED WPLINGING-MACHI'NE.

Specifica-tion forming part of Letters Patent No. 39,512, dated August 11, 1863.

' this' specication, in which- Figure l is a perspective view of my invention; Fig. 2, a transverse vertical section of the same.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to an improved clothes washing and wringing machine of that class in which indiarubber or other elastic pressure-rollers are employed.

The object of the invention is to obtain a clothes washing and wringing machine ofthe class specified, which will be more durable and more economical to construct than those previously constructed.

To this end the invention consists in using, in connection with a pair of india-rubber or other elastic rollers, rollers of wood or other suitable rigid material, so arranged as to keep the elastic rollers in proper position and admit ofthe latter being rotated by the application of power to one ofthe rigid rollers, as hereinafter set forth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it. t

A A represent two metal plates, which are connected by cross-rods a a. These parts form the frame of the machine, and each plate A has two pendent bars, b b', one of which, b, is longer than the other, b. The shorter bar, b, has a clamp-screw, B, passing through it, by which the device may be secured to the tub, the upper edge of the latter fitting between the bars b b'.

C C C C represent four rollers of wood or other rigid material. The shafts o of these rollers have their bearings in the plates A A, and between these rollers two india-rubber rollers D D are placed, one directly over the other, as shown clearly in Fig. 2. The indiarubber rollers D D are not provided with any shafts, and are rotated from one of the rollers O,whiel1 is provided with a crank, E. By this arrangement the india-rubber rollers are made to operate upon the clothes, which pass between them in a thorough manner, equally so as those of the ordinary machines, While the disadvantages attending the operation ofthe last-named machines are avoided-to wit, first, the turning of the rubber roller on the crank or power shaft; second, the soiling of the clothes by iron-rust from the drivingshaft, the sulphur in the vulcanized rubber, which is used for the purpose, causing the shaft to oxidize rapidly; third, the expense attending the ordinary machines, due in a great measure to the securing of the rubber roller on the drivingshaft and the fitting of the rollers in the frame of the machine.

By my improvement the rollers may be readily adjusted in the frame of the machine and removed therefrom, and the rollers, in consequence of being solid, may be cheaply constructed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The employment or use, in clothes washing and wringing machines, of india-rubber or other elastic pressure-rollers, arranged in a suitable frame, in connection with wooden or other rigid rollers, in such a manner that the latter will keep the former in proper position and communicate motion to the same, substantially as herein set forth.
