WASHING- MACHINE.

SPE(JI'IIGl-lJJEIOlQ' forming part of Letters Patent No. 605,721, dated June 14, 1898.

Y Application iiled July 10, 1897. `Serial No. 644,153. (No model.)

To all whom it may con/cern.-

Be it known thatI, I-IANS G. JOHNSON, a citizen of the United States, residing at W'aukon, in the county of Allamakee and State of Iowa, have invented certain. new ,and useful Improvementsin Vashing-ll/Iachines;l 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 theart to which it appertains to make and use the same.

As will be hereinafter fully described and claimed, my invention appertains to washingrnachines, and more particularly to that class thereof wherein a combined 4pumping vand agitating process is set up, the object being to utilize the vacuum introduced for the purpose of more thoroughly cleansing the garments treated.

A further object of my invention is to provide ayielding flexible condition for the parts, thus making it unnecessaryto always hold the handlein a vertical position, which necessity exists in washing-machines of this character.

In the accompanying drawingsFigure 1 is a vertical section showing my invention ready for use, the handle being partly broken away. Fig. 2 is a bottom plan view of the agitating dasher or disk. Fig. 3 is a horizontalvsectiony of Fig. 1, taken on line a a.

It may be briefly stated that my invention consists in a hollow chamber or body, the lower end of which is entirely open, the body being preferably conical in section, and, further, of an operating-handle and means for setting-up a flexible union between the body and the handle thus provided. y

Referring in detail to the several elements,

figures will be used to designate the same,"

the same figure being employed for the same part throughout the views.

In materializing my invention I provide the body 1, which is preferably circular :in horizontal section and conical in vertical section,`

as shown in Figs. 1 and 3. The upper end of the conical body 1 is provided with a central aperture 2, of sufficient diameter to permit the tube 3 to freely move therein and have sufficient lateral play to permit said tube and the handle 4, provided therefor, to loe moved in varying angles out of a perpendicular. The tube 3 has attached to its lower end the agitating-disk 5, provided upon its lower side at proper locations with the reinforcing-ribs 6, the object of which is to reinforce said disk and more reliably hold it in position. Any convenient means for uniting them may loe adopted.

In Fig. 2 I have illustrated the ribs 6 as being integrally formed with the collar 7, the latter being designed to encircle the lower end of the tubular socket 3, to which it is reliably attached by screws 8. Near the upper end ofthe socket 3 I mount in loose vunion therewith the collar or sleeve 9, held in position by a splitkey or bolt 10 or other suitable means. A

Upon the lower end of the sleeve or collar 9 I'form the annular flange 11, designed to prevent the upward movement of the upper end of the coil-spring 12, interposed between said flange and the body. By this interposition of said spring it will be observed that the tube and handle therefor are normally held at right angles to the plane of the upper surface of the body, though the tension of said spring may be readily overcome when bringing the handle out of the perpendicular or when the body is conforming to the outline ofthe clothing to be washed.

As previously stated, the tube 3 passes the upper surface of the body in any preferred ,way, as by screws 15.

By the construction above described it will be readily apparent that the handle may be brought out of the perpendicularwhen the body is raised in a horizontal position, thus permitting the device to be freely operated from anyconvenient point near the receptacle containing the clothing to be treated.

Having thus described the construction of loosely through the aperture 2, and in orden -to prevent the escape of water upward through IOO my invention, the operation or use may be stated to be as follows: The clothing to be treated is placed in a suitable receptacle in the usual way and the desired quantity of water and other accessories added, when t'he open end of the body is brought into contact with the clothing and a pressure brought to bear upon the operating-handle 4, which will overcome the tension of the coil-spring l2 and bring the agitating-disk and supporting-ribs into contact withthe clothing, while the body I will readily conform to the service thereof, thus insuring that all parts thereof will be acted upon and thoroughly cleansed. The act of moving the agitating-disk 5 downward into contact with the clothing tends to create more or less of a vacuum in the body, and apertures I6 are provided in the upper section of the body to overcome this tendency.

It will be clearly apparent that by removing the split key or bolt lO that the collar and operating-handle can be easily removed, permitting the coil-spring to be withdrawn and rendering the interior parts readily accessible for cleansing or other purposes.

While I have described the preferred construction deemed necessary in carrying out my invention, it will be understood that the equivalent thereof is comprehended by me.

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

In a washing-machine, the combination of a body having an aperture in its top, a tube loosely fitting said aperture and having a collar on its upper end and an agitating-disk 0n its lower end, a coiled spring disposed around the tube and located between said collar and body, a yielding gasket encircling the tube and resting on the upper surface of the body and a plate having an enlarged central aperture and an upturned flange resting on said gasket, all arranged as set forth.

In testimony whereof I ailix my signature in presence of two witnesses.

HANS G. JOHNSON.
