WASHING- MACHINE.

Llliiiliit Application le July 21,

efiicient and satisfactory ltor use wherever found applicable.

One of the objects of my invention is to provide a washing machine having a drum of a special shape which may be operated to describe a rocking movement similar to that of a rocking chair rolling back and forth on a horizontal plane or base. This action tends to give a uniform and efficientv movement of the Water or other liquid Within the'tub so as to effectively wash the garments placed therein, necessitating a minimum amount of driving mechanism or power. The load is practically balanced due to the shape of the drum so that there is a tendency to automatically restore the load to equilibrium when the driving power ceases.

Another object of my invention is to provide pockets or chambers at opposite ends of the drum, said pockets being so formed that a pressure is produced therein at one direction of movement of the drum, thereby forcing air and water through the garments, and upon the opposite direction of. movement of the drum, a suction is formed thereat, drawing air and water from the pocket through the garments.

Another object of my invention is to provide deiector or bafile means on the drum at the bottom thereof which will cause the garments being washed to be turned or changed constantly, thus causing all portions of the load to come in contact with the liquid and the pockets, said means also producing a spiral movement oi" the liquid within the drum.

Many'other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from' the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and com- Specificati'on of Letters Patent. Pamejmtd Jun@ 3139 19225 1921. Serial No. 466,433.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Fig. l is a side elevation of my device;

Fig. 2 is a rear end elevation thereof;

Flg. 3 1s 'a vertical section through the drum;

Fig. 4: is a section taken substantially on the line4-4 of Fig. l;

Fig. 5 is a section taken substantially on the line 5-5 of Fig. 6;

F1 6 is a section taken substantially on the line 6 6 of Fig. 5, and

Fig. 7 is a section taken substantially on the line 7 7 ofv Fig. l.

In the drawings, wherein I have illustrated the preferred embodiment of my invention, l `indicates the supporting frame of a machine having a driving mechanism near its bottom enclosed by a housing 2 and upon which is detachably mounted a drum or operating tub 3. The tub or drum 3 is con- Aends thereof are pins or rollers 5, said pins or rollers being adapted to freely enga e in slotted openings 6 provided in the brac ets 7 arranged at the opposite sides of the supporting frame' l, said brackets 7 having a track portion extending substantially in a horizontal plane so as to form a horizontal or Hat bearing plate upon which the curved bottom of the tub is adapted to slide or rock. lf desired, a strip of asbestos or other suitable material 8 is positioned between the tub and the bracket so as to eliminate noise therebetween.

Pivotally attached to one end of the tub 3 is a pitman or connecting rod 9, said pitinan being preferably longitudinaliy yieldable and comprising two telescopic portions 10 and 11 with a resilient spring 12 therebetween, as shown in Figure 7. The tower end of said pitman is connected to a crank 13 driven in any suitable manner, as by an electric motor or the like., positioned Within the housing $3. il. cover plate 14 of a suitable size is arranged on the upper surface of the drum for the insertion and removal of the material to be acted upon. Arranged at oppositeends of the drum, as shown more clearly in lligures 3 and 4l are one or more varies 15, said vanes being curved so as to form substantially curved, tapered pockets 16 opening toward the bottom of the drum. The free edges of said vanes are belovv the center of the tub and preferably about half Way up from the bottom thereof. 0n the inside ofthe tub is arranged a baille or deilecting rib or projection 17 extending from side to side along the bottoni thereof, obliquely or diagonally in a direction thereacross, said rib decreasingly tapering from its midpoint to both its ends and to opposite sides of its base so that a transverse cross-section through said rib would be shaped substantially triangular', as shown in Figure 3.

'llhe rotation of the crank 13 Will operate the pitman 9 to cause thedrum to rock or tilt on the horizontally extending bearing portions or tracks of the brackets 7 the pins 5 being free in the slots' and serving merely to limit and guide the tub in its rocking movement. The telescopic action of the pitman parts and the free insertion and removal of the pins-5 into the slots 6 permits the tub to be readily lifted from the frame Whenever it is desired to do so, as for instance for the purpose of cleaning, repairing, shipping, etc.

ln operation, assuming that the tub 3 has Water or other suitable liquid therein and is loaded to the proper height, the rocking movement thereof. Will cause the liquid therein to follow a path somewhat as indicated diagrammatically in dotted lines in Figures y3 and a, the body of Water splitting at the free ends of the Vanes, asshown, a portion of it following the outer surface of the vanes and forming substantially -a figure 8, While the other portion of the Water tends to move into the pockets 116 thereby causin the air in the pockets to be compressed by t e Water. The movement of the llastmentioned Water is substantially as shown in Figure 4l; that is, it moves in a curved path in a continuous direction Without reversal along the sides and ends of the drum; rilhis is caused by the diagonal rib 17 slopin from the center towards both ends Where y a larger proportion of the Water at the ends of the drum is to one side of the lonV itudina'l center line of the drum, and as t ese areas of majority Water supply are diagonally arranged, the direction of the How of the Water will be governed accordingly and will be in a. curved path about the ends andsides of the drum in a continuous direction .as shown. The material is plunged against the pockets toward I*which'liquiid i having, so that a rinfresco cupping action is produced, whereby the liquid will be forced through the material at the pockets and into the pockets to corn- A in air pressure therein, so that the air and liquidfrom the pocket is drawn or. sucked through the load.' rlfhe creating of an air pressure and a partial vacuum orsuction in the opposed pockets 16 alternates upon each rocking movement of the tub. The oscillating motion of the tub as it rocks to and fro plunges the load against the ends of the vanes where the pockets are arranged, holding them there While the air and liquid is driven therethrough, This action may be called .a cupping action because the material .is held over the pocket while the liquid and au' is forced therethrough into the pocket.

lf desired, handles 18 are arranged at opposite ends of the tub, whereby the tub may be lifted from the frame, or, if desired, the tub may be manually rocked. A drain 19 may be arranged adjacent the bottom of the tub, as shown. 1n case it is desired to vheat the Water in the tub after it has been ecient and sanitary churn, or for any kind of extracting or mixing purposes, inasmuch as the smooth interior of the drum may be easily cleaned, and my description and claims have in mind such a use. p

Having thus described my invention, 1t is obvious that various immaterial modiiica tions may be made in the same Without' de partin from the spirit of my `invention; hence l do not Wish to be understood as limiting myself to the exact form arrangement,

construction and combination of parts herein shown and described, or uses mentioned.
