My invention relates to improvements in washing machines and centrifugal driers, and combined washers and driers. The objects of my invention are:

1. To provide a unitary washer and centifugal drier of great simplicity and which will avoid the necessity of using gears, gear housings, wringers and various other parts now in common use.

2. To provide a combined washer and drier of neat appearance.

3. To provide a belt-drive for washing machine and drier, with means for operating both washer and drier either in unison or separately.

4. To provide an agitator for a washing machine which will cause a considerable mixture of air with the water and increase the bubbling and foaming thereby.

5. To provide means whereby the overflow from the drier can be. directed back into the washer or into a receptacle outside the washer placed at any side thereof. Y

I attain these objects by the means illustrated a in the accompanying drawings, in which,

My machine may be either round or rectangular, but I prefer to build it with a circular base, H, having legs, 12, extending therefrom, and may be provided with castors, 30, with castor wheels, 43.

Upon this circular frame I secure a washer 55 M, rolled therein and having reinforcing wires,

Application for 38 and il, rolled in in the usual manner to reinforce the bottom and top thereof.

An annular lid, II, having its lower edge reinforced with a reinforcing wire, it, rolled therein. rests upon the top of the tub, 24, and pref- 5 erably revolves freely thereon. At the inner edge of the annular lid, It, a slight flange, Ii, is turned up and an annular flange, 9, is secured upon the top of the lid, i3, preferably by soldering, and the flanges, II and 9, form a channel, 10 6, to receive the water from the centrifugal separator and conduct it to the drain trough, 8, which is formed integral with or united to the lid, i3, at one side thereof, to conduct the water away from the separator and into an outside receptacle when desired.

When desired to return the water from the separator to the washer, the opening, 3, from the channel, 6, to the drain through, is closed by the slide, 92, which is pivoted (92) to the 2 Cross-bars, 18, have their outer ends united to the legs and at their center carry a boss, 64, in which an oilless bearing, 65, is mounted.

Arms, 51, are cast integral with the cross-bars, 18, extending upwardly therefrom, and have a boss, 56, cast integral therewith. In the boss is mounted a hub, 55, cast integral with a drive pulley, which also forms a part of the female member, 39, of the separator clutch. The male member, 45, of this clutch, is pinned or otherwise suitably secured to the shaft, 21, the lower end of which is mounted in the oilless bearing, 65, and the upper end of which is mounted in a bearing, I3, to be described hereafter.

The upper end, 69, of the shaft, 21, is tapered and may be squared or otherwise shaped to secure a flrm hold upon a raised boss cast integral with the base of the spin-basket or receptacle, 2 i, of the separator, and the separator may be secured to the shaft by an additional pin, 32, if

Resting upon the top of the spin-basket, 2|, is a lid, 4, having a plurality of fingers, I, extending downwardly therefrom and seating "upon the upper edge of the spin-basket, 2!. The spin basket is preferably cast of aluminum, with a heavy base and with relatively thin sides as shownatil. j

At the center of the top of the frame, '1 I, a heavy boss, $0, is secured to or formed integral therewith, and carries a column, i'l, rigidly cured therein, whichmay'be surrounded by a gasket, 25. The column, I6, is threaded into'tli hub, SI, and the gasket; 25,1s preferably threaded upon the column. At the upper end of the column, II, a circular flange, II, is formed integral therewith.

Within the column, ii, at the lower end thereof, an oiiless bearing, 34, is fltted and within the upper end of the column, H, a similar oiiless bearing, 20, is fitted. A sleeve, 25, has its lower end mounted in the bearing, 24, and its upper end mounted in the bearing, 20. This sleeve, 35,

extends below the bearing, 34, and has secured to its lower end a crank, 10, by pins, 20, or any other suitable means. Within the upper end of the sleeve, 35, I secure the oiiless bearing, II, in which the upper portion of the shaft, 21, is mounted. A similar bearing, 82, is mounted within the lower end of the sleeve, 35.

Upon the upper end of the sleeve, 25, I mount the hub, l2, of the agitator. The upper end of the sleeve, 25, is preferably cut in square form and the hub, i2 has a corresponding square opening cut therein and in addition may be secured to the sleeve, 35, by pins, ill.

My agitator comprises a hollow column, 22, with a plurality of wings'or vanes, 23', united thereto. The outer end of the crank, 10, carries a pin or stud, 19, with an oiiless bearing, 80, mounted thereon, and upon the oilless bearing, 80, is secured one end, ll, of the connecting rod, 36, the opposite end of which is secured upon an oiiless bearing, 31, mounted upon a crank pin, 40, secured upon the surface of the male member. 22, of a cone clutch. The female member, 50, of

' the ease clutch, has formed integral therewith a pulley and a hub.

A boss, 59, is secured to one of the legs by pins or bolts, II, and carries therein an oiiless bearing, 29, within which the hub of the female member, II, of the clutch is revolvably mounted.

This hub is hollow and carries within it an oilless bearing, '0, which in turn has revolvably mounted therein a shaft, 23, to the upper end of which the male member, 22, of the washer driving'clutch, is secured by a pin, 02, or other suitable means. The lower end of the shaft, 22, is likewise mounted in a bearing, 41, secured within a boss, 49, formed integral with one of the cross-bars or cross-frame, II.

A double flanged collar, 00, is secured upon the shaft, 21, and embraced *bya yoke, 48, formed upon the inner endof the lever, 88. The collar. 42, is secured to the shaft, 21, by a pin, 82, and the lever, 89, is mounted upon a bolt or pin, 04, secured in a bias, ll, formed upon one of the arms, 51, the pin, 24, forming a fulcrum for the lever, 40. The outer end of the lever extends through an opening, 92, in the side wall, H, extended downwardly at II, and this opening is so shaped as to form a detent for the outer end of the lever, 09, and hold the male member, 22, of

the separator clutch out of engagement with the.

female member thereof; When the upper end of the lever, I0, is released from the detent, the weight of the shaft and the part secured thereto, will hold the cone clutch in engagement and if desired,aspringmaybeaddedtosecureflrmer engagement of the clutch.

A similar collar, 63, is secured to the shaft, 2!, by a pin, 02, or other suitable means, and is embraced by a yoke, ll, formed upon the inner end of the lever, I, which extends through the side walls of the frame, II, as extended downward at 1|" and form a detent in the same manner shown in Figure 8.

Theweight upon the shaft, 22, will-ordinarily then flow down the drain trough, 8,1nto another be sufflcient to secure the clutch members, 22 and 50, in engagement, but springs may be added to increase the pressure thereof if desired. a

A belt, 4|, is preferably mounted in V-shaped grooves, 4!, formed in the pulleys and may be driven through the pulley, I5, by the motor, 11, secured to an extension of the frame, I l, by bolts, 16, or in any desired manner.

Any desired form of belt tightener may be added to keep the desired tension upon the belt, 4|.

The frame, II, may be extended outwardly as at 14 to form a housing for the washer drive pulley.

, For bearings I prefer to use hard maple wood thoroughly soaked in lubricating oil, although graphited metal bearings or any other desired form of hearing may beutilized.

In the operation of my machine, the washwater is placed in the washer tub, 24, to the proper height, which would be somewhat above the beads, 44. The clothes and soap are then placed in the water and the motor started. The washer clutch is then thrown into engagement and the separator clutch thrown out of engagement. The motor thendrives the washer and when the washing operation is completed, the motor may be stopped; the cover, it, removed, and the clothes taken from the washer and put into the spin-basket; 2|. A fresh batch of clothes to be washed may then be put into the washer, the lid of the spin-basket placed thereon, the motor started and both clutches thrown 'into engagement. The gate, 92, is then closed and the water will immediately enter the channel, 6, until it overflows the flange, I, from which it will drop back into the tub.

The spin-basket, 2|, has its sides inclined outwardly so that the centrifugal force when same is spun at a speed of 700 to 1000 R. P. M., will cause the water from the clothes to rise. and overflow the upper edges of the spin-basket, from which it will pass through the opening, 2, into thechannel, 6, .as described.

When the clothes are properly dried from the centrifugal motion, the spin-basket may be stoppedwhile the washer continues in motion and the clothes removed from the spin-basket.

When it is desired to rinse or blue the clothes, the rinsing water or bluing water may be. put into the spin-basket and the gate, 92, left open. The water out of the spin-basket will tube or receptacle arranged to catch same. When desired, the lid, 4, may be left off of the spin basket, as it will operate without the lid, but when operated without the lid, I prefer to form a small outwardly projecting flange, 2|, upon the top of the spin-basket, to assist in throwing the water into the channel, 6, as shown in Figure 9.

t In the drawings, for clearness of illustration, I have shown the tub, 24, extending nearly to the top of the spin-basket, but it is obvious that the height of the tub may be varied to a considerable extent without departing from the spirit of my invention, it not being n to have the tub extend much above the bottom of the spinbasket and the lid of the tub may be sloped to correspond. It is also obvious that the size and relative proportions of thetub and of the spinbasket maybe varied to suit the requirements of each particular case withoutv departing from the spirit of my invention and the tu h may be flared to allow more space between the tub and the spin-basket. f

In rinsing clothes, as many rinse waters as desired may be used or the same rinsing water may be used a second or third time. Likewise, blueing water may be used repeatedly with successive batches of clothes.

It is obvious that my arrangement of washer and spin-basket may be used with any suitable form of drive and I do not confine my invention to the particular driving means shown. At the same time, said driving means contains substantial advantages and is a great improvement over any of the driving arrangements now in use because it obviates the necessity of oiling. It does away with all gears and the noise incident thereto. It avoids the necessity of a supporting post or column for the wringer and allows all of the machinery to be arranged out of danger of contact with the fingers of the operator.

While I have illustrated and prefer to use cone clutches because of their simplicity, durability, silence of operation and the very small amount of throw necessary to disengage them, I do not confine my invention to this particular form of clutch.

In connecting the connecting rodto the crank pin upon the upper member of the washer drive clutch, I prefer to use a self-aligning ball-bearing and I also use a similar ball-bearing in connecting the other end of the connecting rod to the crank mounted upon the washer drive sleeve, so as to allow suflicient play to make it easy to operate the clutch lever, but any form of connection allowing a slight degree of play, may be used.
