WASHING-MACHINE.

Specification of Letters Patent.

Yatented Jan. 12, 1909.

Application filed March 23, 1906. Serial No. 307,604.

To all whom it may concern:

Be it known that I, ROBERT E. L. JOHN- s'rox, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in \Vashing- Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in washing machines, my object being to provide a device of this character which shall be comparatively simple in construction, economical in cost, reliable, durable and eflicient in use, and to these ends the invention consists of the features, arrangements and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a side elevation of my improved machine. Fig. 2 is a sectional view of the apparatus. Fig. 3 is a detail view of the lower part of the apparatus shown partly in section. Fig. 4 is a similar view, the parts being shown in different relative position. Fig. 5 is an underneath view of the cover and the suction cups which act upon the clothes during the washing operation. Fig. 6 is a sectional view in detail of the washing device shown in connection with the cover of the tub. Fig. 7 is a side elevation of the machine showing the lid in the raised or open position.

The same reference characters indicate the same parts in all the views;

Let the numeral 5 designate a stationary frame work having a bottom member 6 and an upright member 7. The tub or receptacle 8 is mounted to have a vertical movement, and to this end the central portion of its bottom is provided with a vertical shaft 9 extending downwardly through an opening formed in the frame member 6. To the top and bottom of the frame member 6 are applied plates 10 and 12 respectively. These plates are connected by vertical bolts 13. Between the plates and the member 6 'sist of wood or other suitable material.

are located partsl land 15 which may colu- T ie plate 10 is provided with a central collar 16 which enters an opening formed in the part 14. The plate 12 is provided with a collar 17 having ratchet teeth 18 formed on its upper face and adapted to engage teeth 19 formed on the lower extremity of a loose sleeve 20 which surrounds the shaft 9. This sleeve 20 has a slot 21 inclined to the vertical. A pin 22 fast on the shaft 9 projects through the slot 21 for a purpose hereinafter explained. As shown in the drawing the upper extremity of the shaft 9 is screwed into a socket formed in aplate 28 made fast to the bottom of the tub by bolts 2%.

Within the tub 8 are located two coneshaped devices 24 connected by a bar 25 to the center of which is applied an upwardly projecting rod 26 pivotally connected as shown at 27 with an operating lever 28, the latter being fulcrumed at 29 on the upright member 7 of the frame work. To the short arm 28 of the lever 28 is secured an eyebolt 30 held in place by a thumb nut 31. To this eyebolt is attached the upper extremity of a chain or other suitable flexible device 32. The lower extremity of this chain is connected with an eyebolt 33 attached to one extremity of a lever 34: Whose opposite extremity is connected with the stationary frame work below the frame member 6 by a fulcrum pin 35. The shaft 9 normally or when the tub is in its lowermost position, protrudes beyond the member 6. The lower extremity of this shaft engages the lever 34 which lever acts on the shaft to raise the tub when the long arm 28 of the operating lever is moved downwardly.

The tub 8 is provided with a cover 36 whose outer edge engages a ledge formed on the inner surface of the tub a short distance below the top of the latter. The central portion of the cover is provided with a central opening from which passes the rod 26. This rod protrudes above the cover and is connected with the long arm of the lever 28 as heretofore explained.

The frame work is provided with tub-supporting members 37 located on opposite sides of the plate 10.

From the foregoing description the use and operation of my improved Washing machine will be readily understood.

The clothes are placed within the tub together with a suitable quantity of hot water shown in Fig. l.

containing the necessary soap in solution.

After this is done it may be assumed that the tub and the levers occupy the position The long arm 28 of the lever is then forced downwardly whereby a the suction devices 24 are forced downwardly At the same time the against the clothes. lever 34 acts on the lower extremity of the shaft 9 to raise the tub 8. As the tub moves upwardly, the pin 22 acting on the upper edge of the inclined. slot 21 0f the sleeve 20,

causes the sleeve to rotate. .Now as the lever is moved in the opposite direction, the tub moves downwardly by gravity, while the suction devices 2- act on the clothes to cause the cleansing water to pass therethrough since there is a certain amount of suction induced as the water which has entered these cups attempts to leave them as the lever arm 28 moves upwardly. During the downward peated every time the long arm of the operating'lever is raised. It will be observed that during the downward movement of the long armof the lever and the upward movement of the tub as heretofore explained, the clothes within the tub are acted on by the two elements moving in opposite directions, one being the downwardly moving devices 2% and the other the upwardly moving tub.

As the tub makes a partial rotary movement during each upward movement of the long arm of the operating lever, the washing devices 21- are made to act on ditferent portions of the articles to be cleansed. This greatly increases the efficiency of the machine.

During the time of putting'the clothes and water into the tub, the lever 28 is thrown upwardly to a vertical or approximately vertical position (see Fig.7) and the cover 36 is carried over to a corresponding position and bears against a projection 28 with which the lever 28 is provided. This part 28 holds thecover in such position that it will drain into the tub, assuming that the inner surface of the cover contains a'considerable quantity of moisture at the time the lever and cover are raised to the aforesaid position. I

The short arm of the lever 28 is provided with an opening A which registers with an opening B in the upright frame member -7, when the lever 28 is raised to the vertical position. By inserting a pin D inthese registering openings the lever and its attachments may be retained in the raised position.

-An important feature of applicants de vice consists in the fact that the only power exerted during the operation of the machine is that requirecl in forcing the long lever arm 28 downwardly. As soon as this movement. is completed, and the lifting force ceases to be exerted, the weight of the tub acting on the lever '34 moves the latter downwardly and throws the lever arm 28 upwardly, this action being entirely automatic. During this/action the tub and cupshaped washing devices are moving in opposite di: rections and the suction resulting. from this separating movement of the two devices, is a powerful and exceedingly efiicient agent in the performance of the clothes-cleansing function. H

Having thus described my invention, what 7 I claim is:

levers whereby during the, operation of the machine, the tub and the washingdevices therein are moved vertically simultaneously in opposite directions. 7

2. 'In a washing machine, the combination of a vertically reciprocating tub, a vertically reciprocating washing device locatedwit hin the. tub, and suitable means for simultaneously imparting to the tub and washing device a vertically reciprocating movement in oppositedirections, substantially as described. a

3. In a washing machine, the combination with a suitable frame, a tub mounted to have a vertical movement thereon, a washing device located within the tub, an operating lever connected with the washing device above thetub, a second lever connected with the frame below the tub, the latter being provided with a depending shaft which the second lever engages, and a connection bea tween the two levers whereby as the operating lever is actuated, the tub and the wash- 115 ing device therein, are moved verticall simultaneously in opposite directions.

'4. In a washing machine, the combination with a tub, a washing device located therein,

and operating means for imparting a verti- 120 cal reciprocation to the tub and washing device simultaneously in opposite directions and imparting to the tub a rotary movement during one stroke of the reciprocation.

5. In a washing machine, the combination 125 with a frame work, of a tub, a washing device located therein, a depending shaft connected with the lower extremity of the tub, the said shaft being vertically movable in the frame work, a sleeve surrounding the 130 shaft and having an inclined slot therein, the shaft having a pin projecting through said slot, the lower edge of the sleeve being provided With ratchet teeth, a stationary ratchet collar mounted on the framework below the sleeve, and suitable operating means for imparting to the tub and the Washing device a reciprocating movement, the two instrumentalities being actuated simultaneously in opposite directions, the arrangement being such that during the downward movement of the tub, the ratchet teeth of the sleeve engage the ratchet teeth of the collar and lock the sleeve against movement whereby the pin of the tub-shaft is compelled 15 to follow the inclined slot of the sleeve and impart a partial rotary movement to the tub.

In testimony whereof I aflix my signature in presence of two Witnesses.
