Application filed October 20, 1927. Serial No. 227,388.

My invention has for its object to provide a washing machine wherein a centrifugal drler used for removing water from the clothes may be so supported as to reduce the floor space normally occupied by the machine when not in use. In this connection the invention also provides a means for automatically making connection with the driving mechanism when it is moved into position for use, means, however, being provided for disconnecting and connecting the drier with the driving means.

The invention has for its object other advantages and features which will appear on examination of the drawings forming a part hereto, and from the description appended hereto.

The invention may be contained in washing machines of different forms, and toillustrate a practical application 'offthe invention,

I have selected a washing machine containing the invention as an example of such structures and shall describe it hereinafter. The structure referredto, is-shown in the accompan'ying drawings.

Fig. 1 is a perspective view of the washing machine showing the centrifugal drier in a folded or closed position. Fig. 2 is a sectional view of a water collector for collectin the water that iscentrifugally removed rom' the 80 clothes in the drying operation. Fig. 3 illustrates a detail for disconnecting the drier from the driving mechanism. Fig. 4 is a sectional view showing the connecting parts of the washing machine. Fi 5 is also" a sectional view illustrating a etail of the driving mechanism. Fig. 6 is a view of the cover of the washing machine and a top view of 'the centrifugal drier which is mounted in the cover.

The articular washing machine that I have se ected as an example of the various .forms bf washing machine to which my invention may be applied, is of a type well known wherein a centrifugal oscillating member, having one or-more wings, operates to agitate the clothes and by their movement through the water cause the removal of the dirt in the manner well known in the art.

The oscillating member is operated by a suitable electric motor, which also may be used in the constructions embodying my invention,

to drive the drier. Also, such machines are ."usually provided with a cover for closing the interior ofthetub of the machine.

. In the articular form of construction shown in t e drawings, the washing machine 1 is provided with a cover 2 that is hingedly connectedto the tub 3 of the. machine so as to enclose the interior of the tub. The bottom 4 of the tub is inverted pyramidal or conical in form to normally cause the clothes to slide towards the center of the bottom. A lurality I of oscillatable members 5 that exten radially in the form of wings, from a central sleeve 6, are supported on and connected to a spindle 7 that extends through the central art of the bottom of the tub. If'desired, a ish shaped plate 8 may be located beneath the wings .5 and in spaced relation to the central part of ,the bottom 4. The spindle 7 is'operated by a reciprocating rack 10 and a pinionll. The pinion 11 is connected to the spindle 7, while the rack 10 is connected to a crank 12. The crank 12 is connected to a shaft 13 that is pivotally'supported in a suitable platform 14 and'm a boss 15 formed ina housing16. A worm ear 17 is keyed to the shaft 13 and is driven y a worm 18 that is connected to the motor 19. A

When the clothes have been sufliciently worked by the washing machineto remove the soil from the clothes, they are, as is well known, run through a wringer or a centrifua1 drier. In the construction embodying my invention, I have provided a cover 2 that is hingedlly connected to the top of the tub of the was ing machine, and the drier is mounted in the cover 2. The drier is in the form of an inverted frustum shaped, rotatable rece tacle 21. The upper edge of the receptacle is curved inwardly as at 22 and the edge portion is perforated as at 23. When, therefore, the receptacle 21 is rotated at a relatively high speed, the water will be carried upjthe inc ined, or frustumal, wall, and ass out through the openings formedin the inwardly v curve edge portion 22 of the receptacle.

' In order to collect'the water that is thus thrown from the receptacle a split annular member 25 is supported on the cover 2. The annulus 25 is, preferably, formed of two parts that are clamped together by bolts 26 that extend through flanges 27 that are formed at the ends of the parts of the annulus. The annulus has a curved inturned edge portion 32 that, preferably, overlies the inturned edge portion 22 of the receptacle and is provided with a channel 28 that is formed between a ridge 29 and the curved wall of the annulus. The annulus 25 is provided with a mouth 30 to permit the discharge of the water that is collected in the channel 28. Prefer- I located so as to deliver the water, that is gathered in the channel 28, back into the tub 3 or may be so located as to deliver the water outside of the tub and into a'suitable pail or other container, as the receptacle is being rotated and the water is directed through the openings 23 and into the channel 28.

The receptacle 21 is rotated by means of a .friction disc 35 that operates on a ring 36 located onrthe lower edge of the receptacle. The ring 36 rests against the edge of the disc 35 which is rotated by means of the motor 19, operating through the shaft 13, to which it is connected by the

bevel gears

37 and 38. The disc 35 is slip keyed to a shaft 39 which is connected to the bevel gear wheel 38 and is supported on the end of the bracket 40 that is connected to the boss 15 formed on the housing 16. A spring 24 is located intermediate the disc 35 and the bracket 40. The spring operates to take up the vibration that would otherwise be produced by the speed of the rotation of the drier, particularly, when loaded with clothes unevenly. The receptacle is rotatably supported on the cover by means of a pin 44- that is located in an end thrust bearing 41 positioned in a ill-shaped bracket 42 that is secured to, or formed integral with, the cover 2. The upper end of the receptacle is also guided in its rotation by the cover and the outer edge portion of the annulus 25. The receptacle 21 is provided with a lip 43 that extends over the ridge 29 which coacts to hold the receptacle in its rotative position, and also operates to deliver the water, that is ejected through the perforations in the inturned edge portion 22 of the receptacle 21, into the channel 28, and thus prevent the escape of water between the receptacle and the cover 2.

When the drier is in operation, the weight of the cover, the receptacle, and the clothes, resses the ring 36 against the disc 35 wherey good frictional contact is made and good drivin connection is established. When it is desired to remove the clothes, from the drier, the driving connection with the electric motor may be discontinued by means of a cam 45 that is rotatably supported in a bracket 46 secured to the side of the tub ,3 of the machine. The cam 45 is connected to the rod 47 that extends to one corner of the tub and is rotat ably supported in the

brackets

46 and 48. The rod 47 may be provided with a handle 49 whereby the rod 47 may be conveniently rotated to rotate the cam 45. The U-shaped bracket 42 of the cover 2 is provided with-a U-bar 50 that partially surrounds the drier and in position so as to be engaged by the cam 45 to move the ring 36 away from the friction disc 35 when the handle 49 is rotated. Thus the driving connection with the motor 19 may be easily established and disconnected by manipulation of the cam 45.

When the Washing has been completed, the

cover may be closed which inverts the drier connecting the drier with the rotary member in a swing position of the drier.

3. Incombination with a washing machine and a driving mechanism therefor, a centrifugal clothes drier pivotally connected at one side of the drier to the washing machine, and a means for connecting the drier to the driving mechanism in a swing position of the drier about its pivotal support.

4. In combination with awashing machine and a driving mechanism therefor, a cover for covering the tub of the washer and hingedly connected with the washing machine, a centrifugal drier supported on the cover, a rotatable member connected to the driving mechanism, and a means for rotatably connecting the drier with the member when the cover is swung to open the tub.

5. In combination with a washing machine and a driving mechanism therefor, a cover for covering the tub of the washer and hingedly connected'with the washing machine, a centrifugal drier supported on the cover, a friction disc to rotate the drier connected to the driving mechanism, a means for rotatably connecting the drier with the friction disc when the cover is swung open, the drier having an inverted frustumal shaped receptacie and an annulus for collecting the water that is rentrifugally. forced from the upper end of the receptacle. p

6. In combination with a washing machine and a driving mechanism therefor, a cover for coverin the tub of the washer and hing; edly connedled with the washing machine, a centrifugal drier supported on the cover, a friction disc to rotate the drier connected to the driving mechanism, a means for rotatively connecting the drier with the friction disc when the cover is swung open, and a manually operated means for disconnecting the drier from the disc.

7. In combination with a washing machine and a driving mechanism therefor, a cover for covering the tub ofvthe washer and hingedly connected with the washing machine, a centrifugal drier supported on the cover, a friction disc connected to the driving mechanism, a means for rotatably connecting the drier with the friction disc when the cover is swung open to rotate the drier, the drier having an inverted frustum shaped receptacle, an annulus for collecting the water that is centrifugally forced from the upper end of the receptacle, and a spring for yieldingly pressing the disc against the drier.
