April 15, 1930. w. Hou- 1ER WASHING MACHINE Filed sept. e; i928 Patented Apr. 15, 1930 PATENT OFFICE WALTER J'. HOLLIER, OF SE1?. LOUIS, MISSOURI WASHING MACHINE .Application med september e, 192s. serial 1ro. 304,264.

The general object of this invention is to provide a washing machine which shall be entremely simple and compact in construction and which shall be of relatively small a size, thereby adapting it particularly for use in washing the soiled garments of babies and children. v

Stated more in detail, objects of the invention are to provide a vertically disposed tub w or container removably ymounted on an oscillating support to provide novel means for oscillating the support on which the container is removably mounted; and to provide a novel construction of container which in operation l5 will thoroughly agitate the Water and the articles being washed and cause them to be cleaned with great rapidity.

Other objects of the invention relate to details of construction and to novel combina- 20 tions and arrangements of parts all of which will be clear from the description ',of the invention to follow.

In the preferred embodiment of the invention my improved washing machine com prises a base having a motor pivotally mounted at its lower end thereon and provided with mechanism for causing the motor to be osoillated back and forth as its shaft rotates, in the manner of an oscillating fan. The base preferably forms the bottom of an enclosure or casing on the top of which lis provided a suitable ball bearing surrounding an opening for a stub shaft, `the lower end of which is non-rotatably engaged with the top of the motor. The said stub shaft is preferably formed integral with a circular support from the center of which it projects downwardly. Said support is provided with a plurality of apertures and the container is provided on its bottom with a correspondingnumber of studs 4which fit into said apertures, so that as the said support is oscillated by the corresponding movement of the motor, the container will have imparted to it a corresponding motion.

' In the drawing Fig. 1 is a plan view, partly broken away, of my improved washing machine; Fig. 2 is a View partly in verticalelevation and partlyv in section of the same;-Fig. 3 is a top `plan view of the support for thecointaner; Fig.- 4

is a perspective view of the agitator mounted within the tub; Fig. 5 is a section plan view ou the line 5*5 of Fig. 2; and Fig. 6 is a sectional plan view on an enlarged scale, illustrating by dotted lines the paths of movement of certain partscausing the-oscillation of the motor.

Referring now to the drawing, tlie numeral 1I indicates the 'base of the machine which, preferably, is in the form of an enclosed structure having a bottom 2 and a top 3. The bottom 2 on its upper side is provided with a central step-bearing'l and the" top 3 is provided with a` central bearing 5 on its underside and with a ball bearing 6 on its upper 65 si'de, said bearings accommodating a stub shaft 7 passing through them and projecting downwardly from the center of the underside of a circular plate oi` support 8. This plate or support is designed to be oscillated in a manner and by means presently to bedescribed. Numeral 9 indicates the container, which, as shown, is vertically disposed and usually constructed pf sheet metal, such as, tin, copper or the Vlike'. 75

The support 8, as shown by Fig. 3. is provided with a series 0f apertures 10 which, as shown, are three in number; an d the container 9 is provided on its under-side with a corresponding series of studs l1 which are adapted 8O to litsnugly in the apertures 10. lhen the container isthus positioned on the support 'S it will movewith'the `support as the latter is oscillated, as will be understood: The container 9 is preferably provided with a bail. and has a removable closure 13 providedwith a central handle 14 for manipulating it.l

Within the container I .mount means for causing agitation of the water and pf thc articles being washed in the oscillation of said container. This means is shown in Fig. 4 and consists of a triangular-shaped member which is secured along one of its sides to the bottom of the container and has its other side projecting upwardlyl along the wall of 9" the' container and in contact therewith. Ono Way 0f forming this agitatingdevice will be apparent `from Fig. 4, and consists in bending a sheet ofmet'al upon litself to provide a triangular body portion -15 and flanges 16 100 v vertical center.

projecting laterally from one side thereof. These flanges are provided with apertures 17 by means of which the agitator, indicated in Fig,2 generally by the numeral 18, may be secured -to the bottom of the container. When so positioned, the -hypotenuse of this triangular figure will extend from about the center of the bottom of the container to a point located at something less than the distance from the bottom of the container to its It will of course be understood that these dimensions of the agitator may be varied, if found desirable.

For producing` an oscillating movement of the container I provide an electric motor 19 having on its under side a boss 20 which is seated in a step bearing 4, the boss being free to turn in said bearing. On its upper side the casing of the motor is'provided with a hollow boss 21, the openingr in which is non-circular and receives the similarly-shaped lower end 22 of the stubshaft 7. At one end the motor is provided with a casing 23 in to which, as shown by Fig.` 5, extends the motor shaft 24, the outer end of said shaft having a bearing in the end wall of casing 23 as shown at 25. Within the casing 23 shaft 24 is provided with a worm 26 which engages the teeth of a worm-wheel 27, horizontally disposed and mounted on a vertical shaft 28; and mounted on the lower end of the shaft 28 is a crank disc 29 on the under-side of which is eccentrically secured one end of a. Pitman-.rod 30, as indicated at 31 in Fig. 6, the other end of which is pivotally mounted at one side of the step-bearing 4, as shown at 32 in said figure.

It will be apparent th at as the motor shaft is rotated the crank disc 29 will be caused to rotate by the engagement of the worm wheel 27.with the worm 26, the shaft 28 being fast with said worm-wheel and said crank disc;

and as the inner end of rod 30 is fixed against all but pivotal movement on the step-bearing 4, the motorrwill first be moved in one direction until the pivotal connection 31 on disc 29 has passed a dead center, and then in op osite direction, and thus be continuously7 osci lated on its central pivotal bearing 20. This movement of the motor will be imparted to the stub shaft 7, support 8 and container 9 mounted on said support, with the result that the water will be severely agitated, in a well known manner, by the agitator 18. This movement of the water over and through the articles being washed, together with a similar, but somewhat less degree of movement of the articles themselves, results in a very rapid and eflicient cleaning of such articles. Inpractice. the container having therein a number of articles equivalent in bulk to about two linen sheets will effectively wash the articles iri about l5 minutes.

I claim: f
