UNITED STATES PATENT OFFIC GEORGE E. \VOOD, OF DEL NORTE, COLORADO, ASSIGNOR OF ONE-HALF TO FRANK I. PRUDEN, OF SAME PLACE.

WASHING-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 375,858, dated January 3, 1888.

Applic. tion filed March 10, 1857. Serial No. 210,434.

To all whom it may concern,-

Be it known that I,- GEORGE E. W001), a citizen of the United States, residing at Del Norte, in the county of Rio Grande and State of Oolorado,,have invented certain new and useful Improvementsin t ashing-Machines, of which the following is a specification.

This invention relates to washing-machines; and its object is to provide a simple and improved hand washing-machine possessing advantages in point of inexpensiveness, durability, and efficiency, and by the use of which the labor and wear upon the clothing and the time required for cleansing the same will be reduced to a minimum.

In the drawings, Figure 1 is a perspective View of a washing-machine embodying my invention. Fig. 2 is alongitudinal Verticalsectional view thereof. Fig. 3 is a transverse vertical sectional View. Fig. 4 is a detail sectional view taken through the valve-box. Fig. 5 is a detail top or plan view of the valve mechanism, the cap being removed. Fig. 6 is a detail perspectiveview illustrating the valve and slide.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates a bar forming the handle, at each end of which are provided downwardly-extending rods B B, secured to the lower ends of which are transverse tubes G O. A tube 0 is thus provided at each end of the washingmachine, and from each end of the said tubes Oproject down weirdly-extending auxiliary tubes 0, carrying at their lower ends conical shells D. Suitable bracing-strips, E, approximately V shape in crosssection, are provided to connect and brace the pair of conical shells at each end of the Washing-machine.

F designates a longitudinal tube, which eX- tends from one transverse tube 0 to the other and braces the same. The ends of this longitudinal tube open into the tubes 0, and for this purpose the latter are provided with openings or orifices c to receive the corresponding ends of the tube F.

Centrally upon the connecting-tube F is provided a vertically-disposed valvebox, G, preferably of cylindrical form, and having its lower (No model.)

end opening into the tube F through an opening, 9, in said tube, said opening beingsmaller in diameter than the interior diameter of said valve-box. By this construction the water and snds, which pass upward into the tube F'55 when the pou nder is rgglgedmre pFevented from entering the valve-box G and choking the airvalve therein.- This valve-box is provided with a bottom, located somewhat above the opening g in the tubeF and forming the valveseat, and said bottom is provided with a central orifice or opening, g, for the passage of the air. The valve is formed of a plate, H, preferably triangular in shape, which rests normally upon the bottom This plate is acted upon by a vertically-disposed sliding plate, I, setin the cylindricalvalve-box, and provided with an extended top end, i, which end is tapered nearly to a point.

J designates a cylindrical cap-piece fitting over the corresponding valve-box and serving to retain the sliding plate and valve from displacement. At its top the cap is provided with a circumferential series of openings, j, for the passage of air.

In operation the wash-tub is filled about one-half or two-thirds full of clothes, (or a smaller number of articles may be washed, if desircd,) and the suds are then poured over the clothes. To cleanse the latter, the ma- 8o chine herein described is placed upon the clothes, and a rocking motion is produced by moving the handle A and causing the conical shells to rock up and down alternately, thus producing an air-pressure which forces the 5 suds or water through the fabric and cleanses the same with but a small expenditure of labor and a minimum wear upon the clothes. During the operation ofthe device the air passes freely from the conical shells through the tubes 0 G and into the connecting-tube F, and as the device is rocked the shells are raised alternately, and the air being shut ofi' by the valve causes the water to be forced through the clothing by the air-pressure, a vacuum being formed at the base of the conical shells. By the operation of the valve mechanism to shut the air off at the proper time all the airpressure is utilized.

In washingmachines of this class as heretofore constructed escape openings have been provided in the transverse tubes 0, or in short branch pipes projecting therefrom, there being no connection between the transverse pipes at each end of the machine. By this construction a large percentage of the air-pressure is lost by the escape of the airat the openings in the transverse tube. Pounder washing machines have also been heretofore eonstructed with a tube connecting a shell at each end of the machine and formed with branches disposed near each end and having valved plugs.

To obviate the objections above noted and to effect and utilize the complete air-suction are the purposes of my invention, embodying a longitudinal connectingtube opening into the transverse tubes at the end of the machine and providedwith acentrally-located valve, which is alternatelyopened and closed asthe machine is rocked during the operation of washing.

I claim as my invention- The combination, in a washing-machine, with the transverse end tubes, 0, having their ends opening into and carrying the conical shells D, ofa longitudinal tube, F, connecting the transverse end tubes and having its ends opening into "the same, said longitudinal tube being provided on its upper side with a hole, 9, near its center, acylindrical valve-box, G, larger in interior diameter than said hole 9, and disposed over said hole 9, concentrically therewith, a bottom, located in said valvebox somewhat above the tube F, whereby a chamber is formed between said tube and bottom forthe purpose set forth, said'bottom being provided with a hole forming a valve-seat.

and a downwardly-closing slide valve in said valve-box above the bottom thereof.

In testimony whereof I affix my signaturein presence of two witnesses.
