6 I DOMESTIC LAUNDRY EQUIPMENT Application filed March 15, 1930. Serial No. 436,196.

invention relates to improvements in domestic: laundry equipment, and the object of the invention is to incorporate in a laundry structure including a central support,

' pedestal and a plurality of laundry tubs mounted therearound, i means coacting and forming a [unitary structure therewith for performing the washing and wringing operations in any tub desired, and it consists essenthe arrangement and construction of parts all as hereinafter more particularly explained. i Fig. 1 isa perspective view vof my domestic equipment. I I I Fig. 2 is a detail sectional view through the gear box showing the means for driving the washingand wringing mechanism.

Fig. is a sectional plan view on line 3-3 Fig. 4 is an enlarged detail of the detachable connection between the divided members of the washing paddle shaft.

Fig. .5 is a detail of the means for releasably g the clutch lever in'its adjusted position.

Fig.6 is a sectional detail of the paddle 16 taken on line 66 Fig. 1. J Fig. 7 is a sectional detail of the paddle 16 y taken online 77 Fig. 1.

In the drawingslike characters of reference indicate corresponding parts in each fi ure." J" 7' 1 isthe central pedestal provided with a sleeve 2 which is supported thereon to revolve therearound, such sleeve being provided with upper andlower flanges 2 and 2 between which a' plurality oftu'b' supporting brackets 3 'jare swingablymounted as indicated at 4.

' 2 5 andg6 are hot and-cold water supply pipes which extend up through the central pedestal 1 so as to' feed the water into any one of the tubs 7 carried onthe brackets 3.

I do not describejthe above structure furtherin detail as it does'not form part of the present invention and is, only described to make clearr'ny'im'prov'ements.

8 and 9' arebracket supports forming part of the central pedestal 1 and preferably locatedat diametrically opposite points. To

the supports 8 and 9 are secured bracket members 10 and 11. 12 is a wringer to which the flange 13 of the bracket 11 is suitably secured, the portion 14 forming a gear case for the wringer gears. 15 is a cover which is so constructed as to fit any one of the tubs 7. 16 is a washing paddle which is formed somewhat in the shape of a propeller blade, the main body of the propeller inclining forward at an angle as indicated at 16*, the upper edge being offset towards a horizontal direction to form a lip as indicated at 16.

The paddle 16 is carried upon a vertical shaft 17 which is turnably mounted in the cover 15 supported therein by the collar 17 x which is setscrewed or otherwise suitably secured to the shaft member 17. 17 is the upper member of the paddle shaft which is detachably connected to the member 17 by means of a sleeve 18 which is provided with bayonet slots 19 into which diametrically opposite pins 20 extend from the shaft 17. 21 are open ended slots extending from the lower end of the sleeve into which diametrically opposite pins 22 extend.

It will, therefore, be seen that all it is necessary to do when it is desired to detach the paddle and the lower shaft member 17 from the upper shaft member 17 is to raise the sleeve vertically until the pins 22 are carried clear of the slots 21 and the pins 20 into the horizontal portions of the bayonet slots 19.

The shaft member 17, paddle 16 and cover 15 may then be lifted clear of the laundry tub and placedin any one of the other tubs desired and the 7 operating mechanism connected thereto as will hereinafter appear.

23 is a rectangular gear case provided at its upper end with an outwardly extending arm 23 provided with a cover 23. The gear case 23 is formed integral with the bracket member 10 secured as above described to the bracket support 8. 24 is a supplemental bracket carried by the gear case 23 and upon which is mounted a driving motor 25 pro- 95 vided with a drive shaft 26. 27 is a worm secured to the shaft 26. 28 is a vertical shaft extending centrally through an orifice 29 formed in the cover 23 over which extends ahousing 30 having a central orifice 3.1 "l" v f tioned beneath: any-one of the tub's- 7 by;

Having described theprincipal parts involved in my invention '1 will briefly describe theoperation ofthe same I 1 The washing paddle 16 is inserted in any oneof the tubs and the upper and lower members of the paddle shaft 17'and 17 connected by the sleeve 18. The circuitiof the driving motor 25 is then closed driving the motor shaft 26-and-by means of the worm 27 and worm gear 34 driving the vertical shaft 28.

"If it is desired to perform the washing operation the clutch sleeve37 is moved to the closed position by the lever 40 thereby engaging'the gear 35'with the shaft28 and driving the paddle shaft member 17 and 17 throughthe gear 42 v'meshing with the gear 35, the link bar 34 and crank wheel 43. If desired during the driving of the paddle shaft the shaft 45 1nay remain disconnected by meansof the clutch lever55 being set'in the neutral position. ,By throwing the clutch lever:55 to one side or the other the gears 50 and 51 may be alternately engaged so fasto drive the shaft .45 either in one direction or the other and thereby operate the rollersof the wringer 12in one direction-or the other as circumstances require; p

. If desired, of course, the wringer 12 maybe operated and the washing apparatus thrown out of operation by means of the clutch lever40. A r From this description it will be seen that I have devised a verysimple device which will be compact, forming unitary structure, which functions necessary during laundry operation,- having all the required mechanisms close'at hand so-thatitwill'be absolutely under control ofthe operator and thereby enablin'g such operator to perform the entire operation ina minimum amount of time and with a nnnimum amount of labour. :7
