Schedule referred to in these Letters Patent 4and making Pa-fffff n? sme 'l fTo all'whom i'tmay concern:

Be it known that I, JOB RBINON, oflLawreuce,

in the county of `Douglas and in the `State of Kansas,

have invented certain new and useful Improvements` in Washing-Machines; and do hereby declare that the following is a' full, clear, and exact description thereof', reference 4bein g had t0 the accompanying drawing making a part of this specification, in which Figure 1 4 vice, and

`Figure 2 is a vertical longitudinal section of the same, on the line x x of fig. 1. Letters of like name and kind refer to like parts' iu `each of the figures.

My invention belongs to a classof devices having for its object` the cleansing of soiled clothing by mechanical means; and i It consists, principally, in the construction and operation of the rubbers, as is hereinafter set forth.

Italso consists in the general construction and ard rangemeutof vthe various parts of the whole `device,

as is hereinafter specified. In the annexed drawingH v A and A represent the sides of the trough or waterreservoir-secured together at their ends by means of a `vertical and an inclined end piece, B and 0,'1'espectv' ively, and the whole inclosedlat their lower side by' means of la bottom, D, one-half, transversely, of which,

D?, curves downward, as seen in fig. 2.

` A partition, E, extending.longitudinally through the center of the troughfdivides it into two watertight compartments.

Secured transversely across the upper side of the trough, immediately over the center ofthe semicircul lardepression 1) of thebottonn-is a bar, F, having in. and through `the same two slots j, which are placed midway between-the sidesA and the partition E.

An angular metal plate, G, is secured upontlle bar F at each end of the slot f, and serves as va. bearing for `one end each of" two rollers H, which are pivoted within said plates, andextend inward slightly beyond the sides of said slot.' z l Rising vertically from the b'ar F, near its ends, are two standards I, withiuwhich is jonrnaledga shaft,

i K, provided with two cranks 7c, placed directly over the slots f, 'andhaving secured to or upon each end a wheel, I), l,providedjwith a handle, l, extending hori- `zoutally outward from therim thereof.

Journaled upon each crank k is` a bar, M, which, passing downward through the slot within the bar F, has secured transversely upon its inner face a corrugated or groovedboard, N, having a 4length somewhat less than the width ofthe compartment. Within each compartment'is a second grooved board is a plan view of the upper side of my de' or rubber, 0,. corresponding in length to that" before described, and attached to one side'of va short bar,'P, which is pivoted to or upon` a metal rod, Q, passing transversely through the trough.

Two pins or studs R, projecting rearward from the back side of each bar P, near its ends, receive -the small ends of two spiral springs S, the opposite-ends of which are secured to or upon the face of a board, l, that, extending between the side A and the partition E, rcsts within suitable grooves a ande, respectively, cut in the face of each.

As thus constructed the device is ready for use, as follows:

A suitable quant-ity of suds having beensnpplied to each .compartment of the trough, and the soiled clothes placed Within one of said compartments, the

shaft is turned inward, or so as lto cause the 'operat-v ing-'rubbers to pass downward toward the end of the trough, swing forward, and then rise near the fixed or pivoted rubbers, by which means the clothes are rolled over, so as to present a new surface tothe action of the rubbers at eac-h revolution of the shaft.

The/rubber N strikes the clothes at the forward end of the trough, and from thence carries them, together with a large proportion of the water, forward against the second rubber O, after which, by an upward movement, said clothes are thoroughly beaten and rubbed between the grooved surfaces until released by the forward motion ofthe rubber N, when they are shot forward by their weight, and the action of the water, in time to rcceivethe next stroke of the operating-rubber.

It sometimes occurs that an accumulation of clothes at the forward end of the trough would prevent the rubber N from 'passing downward sufiiciently to permit the crank to turn; to guard against which, the lower side of the crank bearing within the bar M is formed by a block, m, that has a iieelongitudinal mod tion within a slot cut in said bar. v

A spiral spring m', placed between the lower ends of the blocky m and the slot, holds the former against the Vcrank with suiiicient force toinsure the operation of the rubber under ordinary circumstances, while, in case of au accumulation of clothes beneath said rubber, as before stated; said spring will yield so as to allow said block to be pressed downward, and enable the crank to complete its revolution.

After the clothes have been washed suliiciently in one compartment, a wringer is placed upon the para titiqn O, and, said clothes passed into the fresh 'snds ,within the second compartment, andtheirplace lled with a fresh supply of soiled or unwashed clothing.

1u order-.to-furnish a hand wash-board for use in rubbing some portions of the clothing that are more than usually soiled, n spring catch, U, is secured at one end upon the upper edge of the board F, and extending forxi'ard engages with the upper end of the bar P, when said bar is turned r11o t-he rear, in which posit-ion the rubber O has a suitable inclination toenable it to be readily used for hand work.

Having thus fully set fol-,th the nature and merits of my invention,

What I claim as new, and desire to secure by Letters Patent, is-- The means employed for 'imparting a motion to, and controlling the operation of the rubbers N, consisting of the rollers H, the shaft K, provided with the cranks k, und the bars M, substantially as shown and described.

Also, in combination with the above, the blocks or boxes m, working longitudinnliywthin the bars M, and held in position against the cranks k bymezms ot' the-spring m', substantially as 'and for the purpose set forth.

Also, the means employed forsecuring in position, and rendering adjustable the rubbers 0, consisting of the bars l), pivoted upon the rodsv Q, the'studs R, the springs S, and the catchesU, substamfoially as shown and described.

In testimony that I claim the foregoing, I have hercunto set my hand, this 30th day of March, 187 0.

JOB ROBINSON.
