Labisky, West Bend, Wis., assignor to The Barton Corporation, West Bend, Wis., a corporation of Wisconsin Application July 16, 1932. Serial 14o. 622,865. 8 Claims. This invention relates to clothe@ washing machines of the household type wherein the water is set in motion by an agitator to effect cleansing of clothes submerged in the water. One of the objects of my invention is to cause the water to flow in an unusual manner to loosely collect the clothes in ring-like formation and to, change the relative position of the clot'-ies to thereby subject the clothes individually tq similar @ 10 water action to insure uniform cleansiiid th6Teof without a rubbing effect by contact with parts of the machine. Another object is to deflect the flow of water induced by the agitator to Increase ihe force and n5'alter the direction of flow of,the water to main@ tain the clothes in loose condition to expedite the cleansing thereof. Other objects are to provide a novel tub adapted for use in washing machines of the kind, 20 wherein a centrally disposed agitator operating about a vertical axis is employed-, and to provide portions in the tub for ine@-easing the effectiveness of the water action in the tub. In the selected embodiment of the invention 25 illustrated in the accompanying &awings Fig. 1 is a vertical section of my washing machine; Fig. 2 is a top plan wherehi the tub lid is removed and certain parts are broken away; 30 Fig. 3 Is a fragmentary horizontal sectional view of the wall o.L the tub; and Fig. 4 is a view takeii substantiaby on the line 4-4 on Fig. 1. Referring to the drawings, the machine in35 cludes a base'or stand 5,having a circular band 6 and an inturned flange 7 which provides,a seat 8 and the rounded lower edge of the tub Is rested on the seat. A rubber ring 9 closes the joint between the seat 8 and the tub 10. The driving 40 inechanisms for'the machine are mounted In a housing 11 carried by the base beneath the tub. Bosses 13, 14, and 15 are provided In the housing and are machined by the use of a suitable jig.to insure aligniment of the shafts mounted therein. An electric motor 16 is mounted on a bracket 16, sec&ed to a cross bar 19' extending below the tub. A pulley 151 ig fast on the shaft of the motor and a belt 171 extends about this pulley and a pulley 18' fast on the shaft 17 io'umaled in the 50 bearings 12 on the housing 11. A pinion 18 fast on the shaft !7 meshes with a spur gear 19 ro_@ tatable on the shaft 20 fast-in t.he boss 13. A spur gear 21 meshes with the spur gear.19 and is mounted on the shaft 22 fast in boss 14. The 55 cover 23 of the housing has a neck 24 and the (CL 68-15) lower end of a sleeve 25 is secured in this neck. The upper end of the sleeve Is secured to a bracket 26 carried by the tub 10. A wringer gear housing 27 of approved form including a clutch raechanis m for operating the wringer is mounted 60 on the bracket 26. A hub 29 on the gear 21 projects into the lower end of the sleeve 25, the lower end of a shaft 30 is detachably connected to the hub, and this shaft extends through the sleeve to the wringer clutch mecham'@m,, - When the 05 iiiotor is set in operation, the piilibn lg,drives gear 19 which rotates gear 21 and'the shaft 30 and when the clutch mechanism is engaged, the wringer is operated. A s . haft 31 is fast in the boss 15 and a segment 32 is rockable about this 76 shaft. One end of a link 33 is pivotally connec - ed at 34 to the segment 32 and the other end of the link is pivotally connected to the gear 19 at 35. Mnien the gear 19 rotates, a reciprocatory movement is imparted to the link 33 which oscil- 75 lates the segment 32. The lov@er end of tkie shaft 36 is journaled in a hearing 231 on the housing 11 and a pinion 37 is secured to this e-haft and is nieshed with the segment 32. As the segment 32 oscillates,- movement is transmitted through pin- 80 Ion 37 to shaft 36 and preferably the ratio between the segment and pinion is such that a movement through an are @lightly more than one hundred and eighty degrees ig imparted to the shaft 36. The shaft 36 extends through a 56 thimble 38 which projects through an opening in the bottom wall of the tub. The '&himble ineludes a flange 39, and a washer 40 is disposed between this flange and the bottom of the ttib. A sleeve 41 unitary with the cover 23 is screw- 90 threaded at its upper end and the lower end of the thimble engages these screw threads, a wa@'ner 42 being interposed between the bottom of, tne tub and the end of this sleeve. VIhen the thimble is tightly fitted in -this screw-threaded end 95 of the sleeve, the washers 40 and 42 are clamped and leakage through the opening in the bottom - of the ttib is prevented. The thimble is unitary with a stem 43 that projects upwardly from the bottom wall of the tub at the center thereof. The '100 shaft 36 extends through the stem 43 and has a polygonal portion 44 at the upper end thereof disposed beyond the end of the bore In the stem. The agitator 45 herein illustrated embodies a sleeve 46 having a bearing portion 47 including a iO5 bore em,bracing the b.earing 48 adjacent the upper end of the stem 43. The lower end of the bearing portioi@ 47 rests on a bearing couar 49 unitw with the stem 43. A bearing couar 30 is provided on the stem 43 intermediate the thim- 110

1,929,747 ble 38 and the bearing couar 49 and a bearing 51' in the sleeve 46 rides on the periphery of this bearing collar. The collar 49 supports the agitator in the tub and the bearing 48 and the bearr) ing collar 50 guide the agitator during oscillation to prevent wobbling or other undesired movement thereof. A clutch 51 is Provided for connecting the agitator 45 to the shaft 36 and ineludes a clutch member 52 having a polygonal 10 opening 53 therein and which is slidable alongthe polygonal end portion 44.. A retaining ring 54 secures the clut6h member 52 on the upper end of sl6eve 46 and a knob 55 is provided on the clutch member to facilitate inovement thereof 15 across the ring. A peripheral shoulder 56 on the clutch member is movable between the upper end of the sleeve 16 and, a flange on the ring 54 to limit movement of the clutch member. Diametrically opposed recesses 57 are provided in the 20 upper end of sleeve 46 and diametrically positioned lugs 58 are provided on the lower end of the clutch mernber 52. When the knob 55 is grasped and the clutch member 52 is forced downwardly, the lugs 58 seat in the recesses 57 and 25., the agitator is connected to the shaft 36 whereby it is oscillated through an are of slightly more than one hundred and eighty degrees. VIhen the knob 55 is grasped and the clutch member is moved upward, the lugs 58 are withdrawn 30 from the recesses 57 and no movem-.nt is imparted to the agitator 45. A.spring-pressed ball 59 is pro-vided in one face of the polygonal portion 44 which seats in a notch (not shown) in the adjacent wall of the polygonal , opening 53 35. to releasably retain the clutch member in the lower'position whereat the shaft 36 and the agitator are interconnected o'r the upper position whereat the agitator and shaft are disconnected. The lower end of the sleeve 46 is enlarged by be40. ing flared outwardly and the peripheral edge of this flared portion Is positioned substpntiary midway between the stem 43 and the periphery of the tub and close to the bottom of -the tub to prevent clothes passing between the agiiator 45 ahd the tub bottom. Vertical radially extending fins project from the outwardly flared por-. tions of the sl6eve 46 and these flns are spaced at ninety degree intervals. 'Ihe flm'or water moving members 60 are in the nature of flat 50 plates and the outer upper comers thereof are rou,nded and the inner upper comers thereof merge into the sleeve a,t approximately the beginning of the flared portio . n of said sleeve. The upper edge of the tub is rolled to provide a bead 55 61 and below the bead the wall of the tub is crimped to provide a flange 62. The lid 63 includes a depending,hange 64 which rests on the bead 61 and the flange -62 to support the lid in tub-dlosing position. In use the tub is sub@tantially two-thirds filled with saponifled water and after use this water is drained from the tub through the drain pipe 65, normally closed by the cock 66. The -foregoing is the preferred form of construction with which ray invention is used but it is to be und6rstood that the invention is not limited to use with a machine constructed in the for6going manner and changes may be niade without departing from the purview of the invention. The cloihes to be washed are thrown into the tub and submerged in the. water therein. The machine is set in operation and the flow of water, as hereafter described, causes the clothes to collect in loose and substantiaby ring-like -formatioii between the sleeve 46 and the tub wall. During the operation of the machine the whole body of water Is caused to flow in an unusual manner to effect thorough. clegming of the clothes. When the agitator is oscillated in the manner described, the *ater in the horizontal 80 zone of the fins is caused to flow tangentially of the agitator toward the waR of the tub and upon enga.-enient with the tub wall, this water flows upwardly along the wall. Movement of the agitator in one direction also affects the bocl-y of 85 water in the tub to impart a eircumfere-iltial movement thereto, horizontally across the tub wall, and this movement is superimposed on the upflow with the result that the water, and particularly that water adjacent the tub wall, tends N to flow in a helical manner, ihe axis of the helix being the center of oscillation of the agitator. As the agitator attains the end of its oscillatory movement in one direction and starts to move in the other direction the tendency toward helical 95 flow in this direction collapses and isimmediately re-created in the other. direction. To -cause the cl@thes to collect in substantially r'mg-like formation and to maintain the collected clothes in loose condition to expedite the cleansing thereof 100 and to cause relative movement of the clothes in the formation, I form in the wall of the tub inwardly directed protuberances 67 and -intermediate thereof I form depressions 67' of a size equal or substantially equal to the protuberances. The 105 altemate protuberances and depressions smoothly merge one into the other and the upper and lower ends thereof are spaced from the top and bottom of the tub and smootlily iherge into the tub wall, and the protuberances and depressions are en- 110 tirely free to shaxp comers and angles which might have an abrasive effect should the clothes contact therewith. The lower ends of the protuberances and depressions are in substantial alignment with the upper edges of the fins while 115 the upper edges of the protuberances and depressions, merge into the tub wQl at or about the height of the upper end of the sleeve 46. The helical flow of water is the resultant of the upflow and the circumferential movement and hence 120 is of appreciable force and gs the water adjacent the tub wall flowing in this manrier flows over the protuberances 67, it is deflecte'd into the adjacent depressions 67' and flows upwaxdly through the depressions with appreciable force. A down- 125 flow of water Is induced adjacent the sleeve 46 by the forcing of the water in the horizontal zone of the flns toward the tub waH. The forceful fiow from the upper ei-ilds of the depressions cuiniinates in a crossfiow at or about the water 130 level and toward the clothes and merges with the dbwnflow below the water level and adiadent the sleeve 46. The protuberances 64, de:ffe@t only that part of the flow adjacent the tub waH and the forceful flow from the depressions culminating .-36 in the crossfiow is affected by the circumferential back and fortli movement.of the water with the result that @tlie direction of the forceful ffow is not, radial but,.constantly changes with the back and forth mov@ement. The tangential flow of water toward the tub wall caiise@ by the fins, the upflow at the tub wall, the crossfiow and the downflow suspend the clothes in substantially ring-like formation in the water and without rubbing effect with parts of the machine. The forceful flow of '.45 w@ter from the depressions maintains the clothes in loose condition and causes them to move about in the ring formation so that the clothes are individually subjected to the various water aetigns in different parts of the Wb ar),d are there-

-1,929,747 3 fore cleansed uniformly. The constant change in moving means extending upvvardly from the botthe direction of the forceful flow of water from the depressions also has the effect of maintaining the clothes in loose conditioa and of causing the -@lothes to turn over upon themselves which additionally expedites the cleansing thereof and inasmuch as the protuberances deflect the tendency toward a helical flow there is little, if any, tendency toward shifting of the ciothes eircum10 ferentiauy in the tub. Biit inasMrLeh as the forceful crossfiow maintains the clothes in loose condition and coristantiy chatiges the relative position of the clothes. uniform and ral-oid cleansing is effected by the water action in the tub. 15 While the invention has been described in coiinection with an oscillating Agitator, it is to be understood that the protuberances ai).d depressions will increase the force of the crossfiow irrespective of the manner in which the water flow tliere20 across is induced.,
