which the articles to be washed are carried,

and two wash-boards, which have reciprocating motion in contrary direction and rub the wash on each side sufficiently while passing between to become cleaned ready for being wringed; and it relates, secondly, to the combination of the above-'mentioned bands and boards with soap-boxes or holders applied on each side of the wash; and it relates, thirdly, to the combination of the above mentioned devices for washin g with a pair of elastic rollers acting jointly with said bands to wring the wash automatically, ready for drying.

In the annexed drawing, Figure l repre sents a vertical longitudinal section of the washing machine with my improvements. Fig. 2 is a top view of the same; Fig. 3, a detached vertical section of the soap-holder or box.

Similar letters of reference indicate corre-vl I spending parts in the several iigures.

General Description.

A represents the basin of the machine, which contains the water for washing and the working parts of the machine. Said basin A is of rectangular form. It is supported upon legs B1B at av proper height convenient for the operator to work on it. It maybe constructed of wood or other suitable material to manufacture it for a limited expense. C C represent a pair of feed-rollers; E E, a pair of rubber or other elastic rollers for wringing the wash. D D are two wash-boards. F and G G are guide-rollers, which all work and have their bearings in and between two stationary side frames, H H, located within a short distance along the sides of the basin A. I I and I I are both endless bands, which carry the wash first between the soap and vsoap-holders J and J', from thence between the wash-boards is delivered upon the stationary receiving:

board K; for which purpose the bands I I are stretched over the lower feed roller C and lower wringing-roller E, and their upper part i passes over the lower wash-board D, under the guide-roller F, toward and over the lower wringing-roller E, and their lower part passes and returns under the lower guide-roller G to the said feed-roller C, while the bands I I' are stretched over the upper feed-roller O and upper wringing-roller E, and their lower part passes under the upper wash-board D under the roller F over the roller E, while their upper part returns under the upper guide-roller` G to the upper feed-roller C. The rubbingfaces of the wash-boards are made corrugated, in the usual manner. The lower board passes through the side frames H H, which have horizontal slots L L through them for the purpose, and said board receives reciprocating motion by means of a pair of cranks, M, attached or formed on the shaft ofthe lower wringingroller E, on which the handcrank X Vis secured, and by means of two pitmen which are pivoted to said"` board and pass over the pins of said cranks M M. The upper board D slides on guide-strips N N, which project from the side frames H H inwardly, and it is caused to slide in contrary direction to the lower board and receives motion by means of a chain or belt, O, of which one is applied on each of its ends, which passes around guiderollers P P, which are tted loosely upon the shafts of the rollers G and F, while said belt isl permanently secured to the boards, clearly shown in Figs. 1 and 2. In front of the feed, rollers G C are employed, on inclined feedboard Q, for placing and laying out the wash, sol as to feed it in a spread condition to the rollers C (l. The journals of said rollers have springs to allow the rollers to yield and move apart in accordance with the varying thickness` of the wash passing through said rollers. A similar provision is employed on the rollers E E, for wringing and on the guide-rollers G G for the yielding of the varying thickness of the wash, and for keeping the band I and I in stretched condition. The lower washboard slides solidly upon the edges of the slots L L. The upper hoard can raise and does bear with its weight upon the wash. To provide the soap in the holders to rub the wash equally regardless of the wear and the variation of the thickness of the wash, I furnish the lower holder with a spring or springs, It, which press the loose bottom, upon which the soap is rested, upward, and furnish the holder of the upper soap with a pivot, as shown, by means of which said holder is ab, tached to the basin A and can raise and lower, and that the soap held therein will follow and rub the wash in passing under it.

Claims. What l claim, and desire to secure by Letters Patent, is-f 1. The combination of the hands I and I and boarols` D, operating'snbstantially as Witnessem R. Bouman, JeCQBFUGHs
