WASHING MACHINE Application filed October 31, 1927. Serial No. 229,928.

My invention relates to improvements in 1 Washing machines and the objects of my invention are:

1. To rovide a washing machine having a 'mova le perforated clothes container mounted within the tub of the machine;

2. To provide means for giving to such container a reciprocating vertical motion and a horizbntal, reciprocating rotary motion simultaneously;

3. To provide a mechanical movement which will transmit from a crank shaft a reciprocating rotary and a reciprocating longitudinal movement simultaneously, to a 4. To rovide simple means for increasing the owage of the water through the clothes in a washing machine. 7

I l attain these objects bythe means illusm trated in the accompanying drawings, in which,

Figure 1 is a vertical section of a washing machine containing my improvement, on the line 1-1 of Figure 2, but showing the g5 gear housing and wringer drive shaft housing in elevation; Fig.2 is a cross-section on the line 2-2 of Figure 1; Fig. 3 is a detail view of the bottom of the crank mechanism; Fig. 4 is a detail showing a side view of the crank swivel in section; Fig. 5 is an enlarged sectional detail of the upper end of the drive shaft and the tubular member of the clothes receptacle; Fig. dis a cross-sectional view on the line 6-6 of Figure 5; Fig. 7 is a sectional detail on the line 2-2 of Figure 1 showing a modified form of clutch which may be utilized to drive the swivel crank but showin the clutch and rocker shaft and the main drlve shaft in full; Fig. 8 is a sectional detail showing an alternate form of the top of the tub; Fig. 9 is a detail side elevation of the clutch shown in Figure7; Fig. 10 is a detail of an alternate form showing the sleeve,'57, of the arm, 2*, splined to the shaft, with s lines, 57", and with collars, 57', adjacent thereto, the sleeve, 57, being in section.

My preferred form of washing machine comprises a circular-base. housingor hollow support, 55', supported upon brackets, 17,

mechanism with the socket member of the and casters 17 which may be secured to the base housing in any of the common methods. The housing 55', is preferably made of light sheet metal and a heavier base plate, 15,- is secured therein to which is bolted a supporting column, 11, the upper end of which is bolted to the circular plate, 56, which forms the top of the'base housing, 55', and also the bottom of the tub, 37. A tube, 44, is secured in the upper end of the column, 11, and the lower end thereof is secured against upward movement by the lock nut, 12, which is threaded upon the lower end of the tube, 44. A bushing, 49', is secured around the tube, 44, within the lower end of the column, 43, upon which the column, 43, revolves. This bushing may also be threaded or otherwise suitably secured to the tube, 44,

to secure same against downward movement.

A hearing plate, 52, is bolted to the bottom, 56, of the tub, and forms a stug-box to prevent leakage around the tube, 44. The tube, 44, extends upwardly above the water level of the tub, 37, and its upper end is fitted with a bearing block, 46. l

A hearing, 13, isunited to the base,- 15, and a rod, 10, is slidingly mounted within the bearings, 46 and 13, at the upper end of the rod, 10, a square head, 45, is secured by a pin, 49, which fits into the upper end of the column, 43. Packing rings, 46 and 51, are secured around the shaft, 10, to prevent leakage and may be of any suitable material and secured, to the tube, 44, by any suitable means.

The lower end of the'column, 43, is bolt'ed or otherwise secured to the bottom plate, 50,

of a perforated basket or container in which the clothes are placed to be washed andperforations, 41, are'formed in the side walls and bottom of the basket or container, 39.

Transverse vanes, 42, are secured within edge of the container is preferably formed in a roll, 38,. which may be hollow or formed the basket or container, 39, and the upper A crank of'novel form secured tothe shaft, 52. This crank comprises a swivel housing, 8' which maybe secured upon the v shaft, 52, y a pin or key, 20, as shown in "Figure 2, or may be loosely mounted u on the inner endof the shaft, 52*, and secured by a nut, 26, threaded upon the inner end of the shaft with a sliding clutch member, 24,-- interposed between the 'swivelhousing, 8, and the housing,'6, of the gear wheel, 66, as shown. K in Figure-7, thefslidin clutch member, 24,

being splinedto the s aft, 52, and .being embracedb a yoke or fork, 25, mountedin a. suitable tiring, 17", I housin 6, or, operab e by a rocking-bar, 18. The swivel ot er suitable support and housing, 8, has its body made ina channeled form as shown in Figure 3 and a swivel, 53,

"is pivoted to the flanges of the swivel housing, 8, upon the pin, 58, which is preferably located in a line with the longitudinal axis of the shaft-52. The swivel; 53, has a separable section 54, secured thereto by a bolt,56, and the body, 53, ofthe swivel, combined with the separable portion, 54, forms a socket which receives'the ball, 55, formed upon the outer end of the arm, 2, thus forming a hall and socket joint. The outer end of the shaft, 52, is provided with a bevel gear wheel, 63, adapted to drive a corresponding bevel gear, 62, upon the wringer drive shaft, 61-, mounted within the housing, 23. a

The top ofthe tub may be formedwith an inwardly projecting annular portion, 36, sloping downwardly toward the center and with a downwardly extending flange, 47, upon its inner edge and with it rolled or beaded ortion, 48, at its-outer edge. This form 0 "top will tend to prevent splashing and will readily return any splashed water to the tub. Any desired form of cover may be used in connection with this construction. I make no claim for any particular form of cover. I

I prefer, however, to form the top of the tub with a flanged and headed edge as shown in the detail Figure 8 so that the top of the tub will not obstruct the removal of the clothes receptacle.

In' he operation of this machine, a tub, 37, is first filled with water to the desired height. The clothes are then placed in the basket or receptacle, 39, and' the cover put on the machine and the motor started. As the motor drives the crank shaft, 52, the clutch rocking-bar 18, may be operated to throw the' clutchmember, 24, into engagement with the horizontal united to the gear swivel housing, 8", and this will cause the A crank to turn with the crank shaft. The

socket member of the crank will carry the head or ball, 55, in an undulating, circular inch and a half to two'inches, giving the clothes receptacle a vertical movement of three or four inches, will be suflicient. At

.the same time, the .clothes receptacle will re- -ciprocating1y rotate for about one-quarter of its circumference.

It is obvious that as the receptacle, 39, rises,

through the clothes in the receptacle and that .as' the receptacle is lowered the water will enter it through the perforations in the bot- -it will cause the" water to pass downwardly tom and tend to pass through the clothes-- therein in an upward direction. At the same time that this motion of the water is taking place, the rotary motion of the receptacle willc'ause' more or less rotary motion or circulation of the water within the tub and that the reciprocating rotary motion of the receptacle, with its vanes, 42, will cause a very considerable agitation and movement of the water through the clothes. The various movements of water, clothes and receptacle will also cause a considerable admixture of air, with the water the bubbles from which will accelerate the cleansing action,of the water upon the clothes.

When desired to operate the wringer without operating the washing machine proper, the rocking-bar can be thrown so as a to disengage the clutch member, 24. I prefer to mount a weighted head upon the outer end of the rocking-bar 18, upon an arm turned at right angles thereto so that the weight of this head will 'hold the clutch (shown in Figure 7) in or out of engagement as the case may be, but any other suitable means may be .utilized as detents for the clutch.

It is obvious that the-form and proportions of the various parts of my apparatus may be varied within a wide range without departing from the spirit of my inventionand that my crank arrangement may be applied as a mechanical movement to a large variety of mechanical appliances.

It is obvious that the form of construction shown will permit the clothes receptacle to be readily removed from the upper end of the shaft for cleaning purposes and when the top of the tub is constructed in the form shown in Figure 8, the entire clothes recep tacle may be readily lifted out of the tub.

' In Figure 10 I have illustrated the use of splines to secure the arm, 2, to the shaft, 10,

and also collars, 57 secured to the shaft, 10, by set screws. It is obvious that the splines-- or the set screws may be omitted when it is desired. to do awayv with the rotational or vertical movement of the shaft, 10. w
