WASHING MACHINE.

Original application iiled March 14, 1919, Serial 11o. 282,585. Divided and this application iiled July 21, 1919. serial 1ro. 312,176.

To' all whom t may concern:

Be it known that I, OCLESBY ALnEN, Jr.,

a citizen of the United States, and a resi` within and is adapted to be submerged inV the wash water in a tub and is adapted to be rotated continuously in one direction for bringing the wash water in which the cylinder is partially submer ed in Contact with the clothes in said cylin er. This feature of the construction may, however, be varied.

lMy invention is herein shown; as more particularly adaptable to that type of washing machine illustrated in my prior apphcatiton for United States Letters Patent Serial Number 282,585, filed March 14, 1919, of which this application is a division.

The present invention relates more specically to improvements for forcing the wash? water under pressure through the clothes in the cylinder and for withdrawing the water from the tub and returning it thereto for passage through thc clothes over and over again until the clothes have been cleaned.

, The invention consists in the combination and arrangement of the parts shown in the drawings and described in the specification and is pointed out in the appended claims.

In said drawings,

Figure 1 is a vertical section of a washing machine embodying my invention.

Figure 2 is a plan view o f thevtub with the cover removed.

Figure 3 is a detail illustrating the pump and pipe Connections for forcing the water into and withdrawing it from th'e tub.

As shown in the drawings, 10 designates the tub which may be of any suitable shape and is shown as rectangular in plan. It is provided with! a bottom 11 and a removable cover -12 and is supported on legs or stand- 55 ards 13. 14 designates the Clothes receiving drum or cylinder which is of open work construction, being herein shown as made of wood and perforated in its circumferential wall. The said cylinder is provided with a hlnged door 15 through which aess may be had to the cylinder for the insertion and removal of the clothes., and said door is adapted to be locked closed b any suitable form. of locking means 16. he cylinder may be rotatlvely mounted in the end walls of the tub 1n any suitable manner, as, for instance, by the means illustrated inl 1n copending apphcation for UnitedStates tters Patent Serial Number 319,074, filed On the 22d day of August, 1919, which is also a divislon of my aforesaid application Serial Number 282,585. As illustrated in said latter application, said cylinder is adaptedrto be rotated continuously in one directlon` although this feature of the Constructionmay be varied.

,'18 designates a pump shown as of therotary'type which is supported on a mounting board 19 that extends between and is supported on the legs orlstandards 13. Said, 80 pump 1s driven by a motor 20, an electric v motor as herein shown, that is also supported on the mounting board 19, the motor being connected to the pumpthrough the medium of a shaft 21.

22 designates a pipe which leads from the outlet side of the pump 18 and extends horizontally therefrom beneath the tub. Said plpe continues upwardly through the bottom wall 11 of the-tub as a stand pipe 23, and said stand pipe terminates .at its upper end 1n a cross head 24 that is disposed parallel to the axis f the cylinder 14. Said cross head is arranged suitably above the axis ofsaid cylinder and above the water level in the tub, and is provided. on the Cylinder side of the head with a series of spray apertures 25 which discharge at an angle downwardly and inwardly toward the cylinder. Said pipe is made of the full length of the cylinder.

26 designates a stand pipe which is located on the side of the cylinder opposite the cross or distributing head 24, and said pipe extends downwardly through the tub 105 bottom 11 and is connected to the intake side of the pump 18. Said stand pipe-26 terminates at its upper end in a cross drain Or intake head 27 which is `disposed parallel to the cross head 24 and is provided with a series of inlet openings 28. Said cross head 27 is located at a level to be always sublevel of the water in said tub.

' clothes to wash the In the operation of the machine, the clothes are placed in the cylinder and the tub is filled with wash water to about the level indicated in Figure l. Thereafter said cylinderv is rotated, as b power communicated to it through a rive shaft 29 and meshing gears on said shaft and the driving trunnion of the cylinder. The pump is by said motor 20 rotated at high speed, and the position of said cross or distributing head 24 on the stand pipe 23, connected to the outlet `side of the pump, and the angle of discharge of the apertures 25 are such that the water forced by said pump through the stand pipe 24 and into the head is discharged with considerable force directly against the perforated or open work cylinder-and directly on the clothes contained therein, so that the pressure of the waterv is utilized to drive the water throu h the fabric of the irt therefrom. The water, after passing through the cylinder and the clothes, is drawn through the head 27 and stand pipe 26 backwardly to the intake side of the pump. rIhere is, therefore, maintained a circulation of water at considerable pressure and speed against the clothes in the cylinder, and the capacity of the pump is such that a substantial volume of water may be circulated in a given time so that the clothes subjected to the washing influence of the circulating wash water are rapidly cleansed. Moreover, by reasonof the fact that the intake head 27 of the stand pipe 26 is located adjacent to the level of the wash water in the tub', the said intake head has the effect to produce a suction action of the water through the clothes, thereby improving the washing action of the water on the clothes. 'It will be observed that the intake head is located a distance abovethe bottom 11 of the tub, as well also above the lowermost part of the drum 14. By reason of this arran ement of the parts, and becauseof the fact t t said intake head 1s located near the `level of the wash water in the tub the body of water at the bottom of the tub is relatively quiescent, with respect tol the-water discharged from the spray head 24, so that, thereby heavy particles dislodged from the clothes can s ettle into this relative quiet body of water and is not again repassed through the pump. rllhe inner surface of the cylinder may be provided with a number of longitudinal ribs 30 which have the effect tol lift the clothes on the rising side of the cylinder and to throw them inwardly toward the center of the cylinder,

, and this manipulation of the clothes facilitates the passage of the wash water therethrough.

The said motor may be connected to and diS- connected from the pump by the means illus- A trated in my aforesaid prior application Se' rial Number 282,5.85 but this feature of the construction is not herein illustrated.
