p a l a an RUDOLPH RAINALTER, OF KANSAS CITY, 'MISSOURI.

'wasnr'ne macnmn Application filed January 28, 1920. Serial No. 354,601.

T 0 all whom it may concern:

Be it known that I, RUDOLPH RAINALT R,

a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

My invention relates to improvements in washing machines and one object is to provide a relatively simple'and inexpensive machine wherein garments, lace curtains and other articles may be thoroughly cleansed without" being torn or otherwise damaged.

A further object is to provide a light but substantial stand in which the tub of the washing machine may be. nested for ship- .ing machine nested in the frame for shipment.

Fig. 3 is a vertical section on line III III of Fig. 1.

Fig. 4 is a longitudinal section of one of a pair of hinges employed in securing the lid to the tub.

Fig. 5 is a horizontal section on line Vv-V of Fig. 3. F'g. 6 is an enlarged fragmentary section of the bottom of the tub and a drain cock, on line VIVI of Fig. 5. I w

Fig. 7 is an inverted plan view of an agitator. o

In carrying out the invention, I employ a tub 2 made, preferably, of sheetm'etal and reinforced at its upper port-ion with sheet metal angle plates 2 and corner brackets 6.

A pair of handles 8 ,are secured to two sides of the tub 2 to form convenient handholds when the tub is to be moved around. The upper portion of the tub 2 is also reinforced by a wooden frame 10 to which the lid 12 is operablyconnected by hinges 14, having upwardly projecting lugs 16 which support said lid in an inclined position when it is thrown back as indicated by dotted lines, Fig. 2.

' The lid 12 has a handle 18 at its free end and is reinforced at its underside with a wooden frame 20. A wringer support 22 is secured to the top of the wooden frame 10, upon which a wringer (not shown), of any suitable type may be secured for the purpose of wringing out the water from they articles after the same have been washed.

The interior of the tub 2 is reinforced with perforated bafiie plates 24, a spider 26, and cross bars 28. The bafiie plates 24 are arranged in pairs against each side of the tub 2 and are provided at their ends with tongues 30, which enter corresponding recesses 1n the frame 10 and the cross bars 28, and thus hold said baffle plates 24 in position. The cross bars 28 are held in the lower corners of the tub by the spider 26, which consists of a four-way coupling 32, a long rod 34 extendin through said coupling 32 and a pair of sliort rods 36. The ends of the rod 34 fit in recesses 38 in two of the cross bars 28, while the ends of the rods36 fit in recesses 39 in the other two cross bars-28 and in the coupling 32, as indicated bydotted lines, Fig. 5. Preferably, the baffle plates 24, the spider 26, and the cross bar 28 are made of wood and whenever desired canbe removed from the tub by pulling upwardly on the coupling 32 to disengage the ends of the rods 34and 36 from the cross bars 28, which latter, together with the baflie plates 24, can then be removed.

40 designates the agitator for stirring the articles in the tub 2 and carrying them.

around against the baflle plates 24 and over the spider 26. Said agitator consists of a perforated plate 42 provided with a hub 44 and dependlng perforated blades 48, adapted to engage the articles in the tub 2.

The hub 44 of the agitator 40 has grooveand-feather connections 50 with a vertical shaft 52 extending upwardly through a hole 54 in the lid 12 and adapted to be secured to a suitable motor (not shown), or if desired, a hand crank may be secured to said shaft if it is to be actuated by hand power. The groove and feather connections 50 enable the shaft 52 to drive the agitator 40 and also permit ,vertical movement of the'latter' independently of the former, so that said agltator may adjust itself to the bulk of the articles within the tub 2. A set screw 56 threaded through the agitator hub 44 is adapted to rest on top of one of the feathers integral with the shaft 52 and prevent the agitator 450 from dropping off of said shaft 52. 7

60 designates a drain cock connected to the bottom of the tub 2 by a nipple 62 provided at its upper end wit-h a marginal flange 64, which is soldered or otherwise secured to the bottom of the tub and provided with slots 66 to permit all of the water within the tub to drain out instead of a. portion remaining within the tub to the depth of the flange 64, which would be the case if the same were not provided with slots 66. The drain cock 60 may be of any suitable type. Tn the drawings, T have shown it consisting of an elbow 68, a discharge nozzle 70 and a screw plug 7 2 adapted to fit in an annular seat 74 in the elbow 68, and thus shut off the flow of water therethrough from the tub 2. The screw plug 72 has an outer winged terminal 7 6, whereby it may be rotated and the nozzle 70 has screw threads 76 to which a hose may be secured for conducting the water to a sewer or other desired point.

80 designates the stand upon which the tub 2 may be supported while in use, as disclosed on Fig. 1, or in which said tub may be nested for shipment as disclosed on Fig. 2. Said stand 80 is of skeleton formation and consists of four corner standards 82 and braces 84: connected at their ends to said standards82. Each standard 82 is provided near one end with a bracket 86 upon which the tub 2 rests when in either of the positions disclosed on Figs; 1 and 2, it being only necessary to turn the stand 80 upside down to change it from the position disclosed on Fig. 1, to the position disclosed on Fig. 2.

In practice, the tub 2 is filled to the desired depth with water, in which soap or other detergents are placed, and the clothes are then placed within the tub, after which the lid 12 is closed. lVIotion is then imparted to the shafti 52 either with a hand crank as above described or by a motorwhich ma y be fastened on top of the lid 12 by bolts 90. Preferably, an alternating rotary motion is imparted to the shaft 52 and the agitator 40, so that the latter will carry the clothes first in one direction and then another over the spider 26 and against the baffie plates 24 until the clothes are washed.

clean. I The lid 12 is then thrown backwardly to the dotted position, Fig. 2, and carries the agitator 4O therewith, so'that access can be readily had to the clothes. for the purpose of removing the same from the tub. The valve 72 is then opened to drain the water from the tub.

From the foregoing description it will be readilyunderstood that T have provided a washing machine embodying the advantages tion of the tub to reinforce the same, cross bars in the lower corners of the tub: where the side walls join the bottom, bafl'le plates arranged in pairs and secured at their ends in said frame and the cross bars, a coupling, rods connected to the coupling and engaging the cross bars to retain the same in place, and an agitator within the tub to rub articles being washed against the bafile plates and said rods.

In testimony whereof I afiix my signature, in the presence of two witnesses.

RUDULPH RATNALTER.
