lclaim.

This invention relates to clothes washing machines and will be described as applied to the well known domestic clothes washer. It is an improvement on my fluid agency washer fully described in my patents No. Re. 20,424 and No. 2,250,315.

In fluid agency washers. as exemplified by my patents, there is some lack of thoroughness in the washing due to the fact that the clothes and water move together in a uniform cyclic flow with little or no change in therelationship of the clothes to each other or to the'currents of water. It has long been recognised as a. principle or good washing that the greatest washing 'etfectiveness is accomplished when the relative action and movement .of'the clothes and water subiect the complete area of the clothes to infinite varia tions of flexing and flushing action.

Various experiments have been tried to eifect this desired relative movement of the clothes and water and such experiments have indicated that deflector; devices within the tub would produce the desired results. However, the mechanical diillculties of driving such a deflector device through the. bottom of the tub in which a highspeed pump is operated, seriously handicap ei'-. forts along this Further. the economic and merchandising eilects ofvsuch devices were not satisfactory. v The principal object of this invention is to Provide in a fluid agency washer, with a pump mounted within the tub to elect a cyclic flow of cloths andwater, means exterior of the tub to divert the clothes from their normal path in the water currents, thus to rearrange and I interchange the clothes with rm to eachother and the water currents.

Fig. 3 is aside elevations-1 view of the crank clutch race for oscillating the tub. as it would appear on the line 3-3 of. Fig. 2. Now referring to the drawings and, at the outset. to Fig. 1, I support a basering II by conventicnal legs li andfrom the. base ring ll support a circular bracket member I! by means 0! angle iron supports it riveted to the base ring is, as shown. A motor It is mounted in a con ventional manner on the bracket member I: and through dual pulleys il and it drives conventional encased gear in it and II, by means of belt and pulley ons i1 and I1. Although in this case I have shown two gear m, eacn'utilircd for a diflerent purpose, it will be understood that in thepractical embodiment of my invention I may desire to incorporate both gear mechanisms in one case. The scar mechanism it drives a conventional wringer through a conventional wringer column mechanism II. The gear mechanism It drives the tub-oscillating crank it through clutch mechanism as best shown in Figs. 2 and 3. The crank llhas a male clutch jaw W, which contacts and interengages a female clutch jaw II formed on the rotating clutch member 2i slidably mounted on the drive shaft 23 of the gear mechanism it, as. shown. The clutch member Ii is urged into clutching engagement with the crank II by the spring 22, whereupon the jaws II! and 1 ii are engaged to-revolve the crank ll. The

crank it is connected'by the connecting rod 10 to the oscillating arm ll attached to the tub, and thus the entire tub and attached in is oscillated." The clutch Ii is controlled by dual 'yoke arms :4 pivotally mounted on the bracket II with the pins 24' engaging between the flanges of the clutch member II. On the outer ends of the yoke arms is is a roller 25' in contact with the cam 26 mounted on the control rod 21. control rod 21 is actuated by a handle 28 and connects with the crank rod 2! and the crank 22' by means of the pivotal'coupling Ill and the mounting bracket 3i..

Main referring to the central 9 1 l mechaehove the dual pulleys ll and ll driven by the motor is, is mounteda cup friction clutch member 82 to engage an expanding friction member $3 controlled by a flange member 36 actuated by the crank as controlled by the die it.

The member 86 is urged dew by a spring 3b and it he hind by the a t that when die it the friction members 82 and ement'with each other and are drivmotor is with the impeller 3% of the blimp which barges a: y outward currents of water through the annular orifice member 3?.

The tub so is divided hr; a perforate tiem ill to protect the clothes tram the inlet'of the pump. The tub u is mounted on a ring bearing member as supported by an annular rins 38 from the bracket member ll. It will thus be appreciated that the complete tub and pump assembly will be oscillated by the crank is when thecon- 'ingosoillatedbyths crank described,

Thus, when the pump is discharging radially out ward water currentsin the tub II. the tub is be mechanism heretofore tionship oi the various parts of my washing me. chine. I will now explain its operation. v

It will be appreciated, as explained heretoio as well as in my patents No. Re. 20,424 and 2%.. 2,250,315, that the pump at is creating a cyclic rolling flow of clothes and water radially out wardly from the central annular discharge orifice 8i across the perforate partition 66; thence upwardl along the vertical walls of the tub i6; thence inwardly toward thecenter oi the tub and back downwardly toward the partition 36.
