Patented July 21, 1331 UNETE srar tarmac H ARRY J. CRINER, F DAVENPORT, IOWA, .ASSIGNOR 0F ONE-HALF TO A. G. BUSH, OF DAVENPORT, IOWA DRIVING MECHANISM FOR COMBINED WASHERS AND DRIERS Application filed December 3, 1928. Serial No. 323,528.

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 centrifugal drier of great simplicityand which will avoid the necessity of using gears, gear housings, wringers and various other ,parts now 1n common use.

' 1o 2. To provide a combined washer and drier 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.

I attain these objects by the means illus trated in the accompanyingdrawings, in

' which,

Figure 8 is a detail of the detent for the drier starting lever.

Figure 9 is an enlarged detail section view showing an alternate form for the upper edge of the spin-basket and the channel formed upon the inner edge of the washer.

My machine may be either round or rectangular, but I prefer to build it witha circular base, 71, having legs, 72, extending therefrom, and may be provided with castors, '30, with castor wheels, 43.

Upon this circular frame I secure a washer body or tub, 24, reinforced with beads, 19 and 44, rolled thereirt and having reinforcing wires, 38 and 14, rolled in in the usual manner to reinforce the bottom and top thereof.

An annular lid, 13, having its lower edge reinforced with a reinforcing Wire, 16, rolled therein, rests upon the top of the tub, 24, and preferably revolves freely thereon. At the inner edge of the annular lid, 13, a slight REESSUED flange, 11, is turned up and an annulair flange, 9, is secured upon the top of the lid, 13, preferably by soldering, and the flanges, 11 and 9, form a channel, 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, 13, 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 flange, 9, adjacent the opening, 3, therein.

Cross-bars, 78, 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, 57, are cast integral with the crossbars, 7 8. 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, 27, the lower end of which is mounted in the oilless bearing, 65, and the upper end of which is mounted in a bearing, 73, to be described hereafter.

The upper end, 69, of the shaft, 27, is tapered and may be squared or otherwise shaped to secure a firm hold upon a raised boss cast integral with the base of the spinbasket or receptacle, 21, of the separator, and

inum, with a heavy base and with relatively thin sides as shown at 31-. I

At the center of the top of the frame, 71, a heavy boss, 90, is secured to or formed integral therewith, and carries a column, 17,

ri 'idl secured-therein which ma be sur-' rounded'by a gasket, 25. The column, 16, is

threaded into the hub, 90, and the gasket, 25,

is preferably threaded upon the column. At

the upper end of the column, 17, a circular flange, 15, is formed integral therewith.

'VVith'in the column, 17, at the lower end thereof, an'oilles s bearing, 34, is fitted and within the upper end 'of the column, 17, a similar oilless bearing, 20, is fitted. A sleeve, 35, has its lower end mounted in the bearing, 34, 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, 70, by pins, 26, or any other suitable means. Within the upper end of the sleeve, 35,1 secure the oilless bearing, 73, in which the upper portion of the shaft,'27, is mounted. A similar bearing, 82, is mounted within the lower endof the sleeve, 35.

Upon the upper end of the sleeve, 35, I mount the hub, 12, of the agitator. The upper end of the sleeve, 35, is preferably cut in square form and the hub,.12, has a corresponding square opening cut therein and in addition may be secured to the sleeve, 35, by pins, 10.

My agitator comprises a hollow column, 33, with a plurality of wings or vanes, 33, united thereto. The outer end of the crank, 70, carries a pin'or stud, 79, with an oilless bearing, 80, mounted thereon, and upon the oilless bearing, 80, is secured one end, 81, of the connecting rod, 36, the opposite end of which is secured upon an oilless bearing, 37, 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 cone clutch, iizlifOlnlGd, integral therewith a pulley and a A boss, 59, is secured to one of the legs by pins or bolts, 51, and carries therein an oillessbearing, 29, within which the hub of the female member, 50, of the clutch is revolvably mounted.

This-hub is hollow and carries within it an oilless bearing, 66, 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, 53,

with one of the cross-bars or cross-frame, 78.

A double flanged collar, 60, is secured upon the shaft, 27, and embraced by a yoke, 46, formed upon the inner end of the lever, 89. The collar, 60, is secured to the shaft, 27, by

a pin, 62, and the lever, 89, is mounted upon.

a bolt or pin, 84, secured in a boss, 83, formed upon one of the arms, 57, the pin, 84, forming a fulcrum for the lever, 89. The outer end of the lever extends through an opening, 93, in the side wall, 71, extended downwardly '-at.71, and this opening is so shaped as to form a detent for the outer end of the lever,

89, 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, 89, 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, a spring may be added to secure firmer engagement of the clutch.

A similar collar, 63, is secured to the shaft, 23, by a pin, 52, or other suitable means, and is embraced by a yoke, 61, formed upon the inner end of the lever, 61, which extends through the side walls of the frame, 71, as extended downward at 71 and forms a detent in the same manner shown in Figure 8.

The weight upon the shaft, 23, will ordinarily be suflicient to secure the clutch members, 22 and 50, in engagement, but springs may be added to increase the pressure thereof if desired. U

A belt, 41, is preferably -mounted in V-shaped grooves, 48, formed in the pulleys and maybe driven through the pulley, 75, by the motor, 77, secured to an extension of ;the frame, 71, by bolts, 7 6, or in any desired manner. A

Any desired form of belt tightener may be added to keep the desired tension upon the belt, 41,

The frame, 71, may be extended outwardly as at- 74 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 hearings or any other desired form of bearing may be utilized.

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 then drives the washer and when the washing operation is completed, the motor may be stopped, the cover, 13, :removed, and the clothes taken from the washer and put into the spin-basket, 21. Afresh 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, 11, from which it will drop back into the tub.

The spin-basket, 21, 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 spinbasket, from which it will pass through the opening, 2, into the channed, 6, as described.

When the clothes are properly dried from 1e centrifugal motion, the spin-basket may be stopped while the washer continues in motion and the clothes removed from the spin-basket.

lVhen it is desired to rinse or blue the clothes, the rinsing water or bluing Wager may be put into the spin-basket and the gate, 92, left open. The water passing out of the spin-basket will then flow down the drain trough, 8, into another 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 thelid, but when operated without the lid, I prefer to form a small outwardly projecting flange, 21, upon the top of the spin-basket, to assist in throwing the water into the channel, 6, as shown in Figure 9.

In the drawings, for clearness of illustration, 1 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 necessary to have the tub extend much above the bottom of the spin-basket and the lid of the tub may be sloped to correspond. lt is also obvious that the size and relative proportions of the tub and of the spin-basket may be varied to suitthe requirements of each particular case without departing from the spirit of my invention and the tub may be flared to allow more space between the tub and the spin-basket.

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 itobviates 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.

lln connecting the connecting rod to the crank pin upon the upper member of the washer drive clutch, I prefer to use a selfaligning 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.
