WASHING-MACHINE.

Specification of Letters Patent.

Patented Aug. 9, 1921.

Application filed November 3, 1919. Serial No. 335,267.

I '0 all w 700m it may concern Be it known that 1, WILLIAM F. BLAKE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful lVashing-Machine, of which the following is a specification.

My invention relates to improvements in washing machines in which an open cylindrical agitator operates in connection with a clothes spreader in a round tub; and the objects of my invention are, first to provide the most eflicient method of agitating clothes, water, and soap in combination;

second, to provide a central clothes spreader to aid in keeping the garments moving; and third, to provide a collector for the dirt and sediment in the water.

An additional object of this invention is to provide a construction utilizing a drum as an agitator and centrally apertured at the ends to permit clothing and water to pass upward and downward through the apertures on reciprocation of the agitator or drum. 1

I attain these objects by'the mechanism illustrated in the accompanying drawlng, in which 1 Figure 1 is vertical section of the washing machine; Fig. 2, a plan View of the open cylindrical agitator; and Fig.- 3, a plan v1ew of the clothes spreader and dirt collector.

Similar numerals refer to similar parts throughout the several views.

The round tub 1 of the washing machine has a cover 2. 3 is the circular wall of the open cylindrical agitator which is open at the top and bottom and which has the flange 15 on the bottom, the curved flange 5 near the top, and the rubbing ribs 6 on the inside of the wall 3. V 4 is the cross bar connecting the cylindrical agitator 3 to the shaft 7 and held from coming off by the thumb screw 8. On shaft 7 just below cross bar 4 is the collar 9 which is rigidly fastened to the shaft 7 by the rivet 11, and which has on its upper surface two projecting lugs 10 which enter openings in cross bar 4 and so keep cross bar 4 in its proper position on shaft 7.

The sleeve 12 has the flange 28 at its base and extends through the bottom of the tub 1 being fastened in position by the nut 17. Between the flange 28 and the tub bottom is the rubber gasket 16 to prevent the water from leaking out. 13 is the dome shaped clothes spreader and dirt collector which is slipped over the sleeve 12 and fits closely around same at the top. The rubbing ribs 27 are in the upper part and openings 14 in the base catch the dirt and sediment in the water as it passes over them and this dirt is kept under the clothes spreader and dirt collector 13.

30 shows the angle iron legs and 26 the brace under the tub, this brace 26 has an opening 18 in the center in which nut 17 can be turned to tighten sleeve 12 and gasket 16. 19 is the lever fastened to one leg of the washing machine by pivot 24 and to shaft 7 by the pivot 23. 20 is the upper arm of the lever fastened to the arm 19 at 22 and having the handle 21 at its upper end. The lug 25 is fastened to the leg of the washing machine and has the spring 29 attached to it, the other end of the spring being attached to lever 19.

In the practical operation of my washing machine water and soap are put in the tub, and garments are placed inside of the open cylindrical agitator 3. Then the operating lever 19-2O is pushed up and down moving the shaft 7 up and down in sleeve 12 and so causing the agitator 3 to move up and down. As the agitator 3 is;pushed down it displaces the water and forces it upward, through, and around the garments, and also forces the water and clothing over ribs 6 and on up to flange 5 which turns them back toward the center of the bottom of tub. Upon movement of the agitator or drum 3 upward, clothing and water previously moved into the drum by the downward movement thereof is drawn downward by the suction produced by upward movement of the agitator in conjunction with the action of gravity. comparatively rapid reciprocation of the agitator or drum therefore first forces the clothing and water upward by an equal pressure upon all sides and then draws the same forcibly downward and, as this action is substantially uniform in both directions of movement, the clothing does not become tangled or knotted as in some other types of agitators especially when used with a spreader, substantially as shown at 13 in Fig. 1, extending upward into the drum. As the garments are being agitated in the water, they continually come in contact with the clothes spreader 13, the dome shaped sides through and is retained under the clothes spreader and dirt collector 13. After the washing is finished this dirt collector 13 is easily taken out and the machine cleaned.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

l. Ina washing machine, a substantially cylindrical tub, a cylindrical drum vertically movable therein and having an inwardly extending flange at both the top and bottom provding apertures in the drum ends of a diameter less than that of the drum, the aperture at the bottom of the drum being of suflicient area to permit water and clothing to pass therethrough into and out of the drum.

2. In a washing machine, a tub, a drum movable vertically therein, said drum conforming substantially to the shape of the tub and having a series of vertically spaced inwardly extending flanges providing a central unobstructed area permitting movement of the clothing and water into and out of the drum, and a spreader member positioned centrally of the tub extending upwardly into the said central area of the drum substantially as and for the purpose described.

3. In a washing machine, atub or receptacle, an agitator of cylindrical form and having an upper and a lower inwardly extending flange, the lower flange providing a central aperture through which the water and clothing may pass into and out of the agitator, the upper flange extending inwardly and thence downwardly providing a central aperture approximately equal to that of the lower flange, and means for reciprocating the agitator.

a. In a washing machine, a tub, avertically movable cylindrical agitator ap'ertured at the bottom to permit water and clothing to pass into and out of the agitator, and an inwardly and downwardly extending flange at the uper end of the agitator providing a deflector for the water and clothing passing into the agitator.

5 In a washing machine, a substantially cylindrical tub, a cylindrical drum of a diameter slightly less than that of the tub permitting its ready movement therein, the drum having an inwardly extending flange at the bottom providing a central aperture, a vertical reciprocable shaft extending up- 'ard through the bottom of the tub, a bar extending across the top of the drum attached to the upper end of the shaft and means connected with the lower end of the shaft for reciprocating the same.

6. In a washingmachinqa tub, a hollow sheet metal drum reciprocable therein, said drum having a central opening at the lower end and closely fitting the tub whereby downward movement causes the'major portion of the clothing and water to be forced upward through the opening and reverse movement drawing the water and clothing downward therethrough, and a substantially cylindrical central spreader member stationarily positioned at the bottom of the tub extending upward into the drum.

7. In a washing machine, a tub, and a cylindrical drum or agitator having an inwardly extending flange at its base providing a central. aperture, and'a curved flange extending inward and downward near its top to engage and outwardly deflect water and clothing moving upward through the interior of the drum on downward movement thereof.

8. In washing machine, a tub for water and clothing, a drum vertically reciprocable therein having an inwardly extending flange at the bottom providing a central aperture less in diameter than the diameter of the drum, a rod extending upward through the bottom of the tub and centrally through the said central aperture of the drum, means for connecting the rod with the upper end of the drum, and a housing for the shaft extending upward from the bottom of the tub into the drum.
