It is an object of this invention to provide a washing machine of the type wherein the o washing cylinder isy rotated in a casingvfory cleansing clothes, contained'therein and is then lifted from Vthe casing' to Vone side thereof so that the clean garments will drop from thecontainer. y j Y v The invention has specialreference toiin-` proved power mechanism for rotating the washing cylinder in alternate directions in from, the casing.l

' designates the casing or housing ofthe washing machine havingiwsuitablej side walls 1925.7 serial No. 50,076;` y

Thisfcasing isv preierabiyl "pi-ended with a movable door orV closure 3j carrying segmem n tal side sections 4, which closurefis connectedV to the casing by suitable pivots V3ak andcapahle' ofbeing moved to a position to permit the container within the washing machine -to be constituting tlieloearings for the washing cylinder. These trunnions seatV within suitable loearings 8 formed in the side walls of the casing and it is upon these trunnions that the washing cylinder rotates. The spider furthermore hasperipheral gears, 9 constituting' the driving gears forr alternately rotating the washing cylinder in thev casing. One spider is ldisposed at each side 'o'f'fthefcylinderandf is con-nectedthereto byholts or f the like. lftl will be'understood that the Vwashing cylindery during a washing operation rotates in one direction, and thenin another to most effectively wash garments contained i therein. The presentinventionv "embodies a motor mechanism for imparting this rotary -motion to the washing cylinder. This cyl# inder is rotated'in the followingmanner:

Seated upon a motor. supp'ort'lOr is an elecand y operates in another .tric motor 11. This' motor is Vprovided with {including a sliding coupling 12a, extending` througha' housing 13 and carries withinthe o housing? a driving gear 14. The shaft 12 y l'thenv extends to a-coupling 15 where it is loosely coupledfwith a control lshaft-,.16 which willV he more fully hereinafter described.' f'vlhe' gear 141 in the housing 13 meshes; l

one of a pair of gears 17 or 18. The gear 17 is the gear employed for operatingor rotating the washing cylinder. The gear 18 is utilized for lifting' the cylinder from the casing in a manner which will later appear. Assuming that the motor is operating due to the admission of current thereto, which current is controlled by the operation of the end lever 13 at one end of the machine, which lever carries a pair of' extensions 14 beyond its pivot, each eXtension being adapted to engage a switch plug 15', one of said plugs being arranged so that when it is depressed the current is supplied to the motor and the other plug is arranged and constructed so that when it is depressed the supply of the current to the motor is dis.

continued. The motor, is, upon the operation of this lever, thrown into circuitfwith` a source of electrical energy and the rotation of this motor rotates the shaft 12, gear 14, gear 17, which latter gear is keyed to the shaft 19 carrying, at each end sprocket wheels 20. These sprocket wheels receive chains 21, which mesh with sprockets 22 `keyed to the shaft 23 disposed at the rear of the man chine and journaled in suitable bearingV 2d. The driving shaft 23 carries apair of separated gears 25 mounted within suitable housings 26 projecting from the rear of the machine. These gears enter or pass through openings in the casing 1 and mesh with the peripheral gears 9 carried by the spider, 6. Obviously the rotation of the shaft 23 imparts a rotary movement to the washing cylinderthrough the driving devices herein described. This cylinder is driven alternately in opposite directions, the motor having suitable controls which are well known in the art for reversing its direction of rotation at determined time intervals. lnasmuch as' such mechanisms are so well known in the art it is not deemed necessary to disclose this control in detail. It will be understood that as long as the handle 13 is coacting,` with the starting switch this rotary movement of the container 1 continues. When it is desired, however, to remove the clothes from this container the rotation of the container must cease, but in order that the container may be elevated or lifted from the casing 1, priorto lifting' this container it is desirable to lock the sameagainst rotation and `in a position where the door openingin the container is `directed toward the floor of the laundry or the like. I have described this braking` mechanism in detail in my co-pending` application Serial No. 50,075, but the same will be briefly referred to herein, One of the trunnions 7 of the container is received in a housing; 27 having dispd ,il therein a brake drum 23, which drum is keyed to said trunnion 7. A brake band 29 is disposed around thisy drum, said band being' mounted at one end on a support 30 while `face 37.

its other end is formed with a loop 31 in which there is provided an eccentric or cam 32. The cam is mounted on a shaft 33 which ertends through the housing 27 and obviously when this cam is rotated it applies or re moves the brake band from contact with the drum. lt is essential that the application of the brake be so timed that the container will be stopped in its motion at a position where the discharge opening therein directly overlies the floor of the laundry so that the garments will fall through this discharge opening. W ith this in mind the trunnion 7 carries a brake operating element 34, the periphery of this element engaging a roller 35 on an operating` arm 36 which carries a dog `The shaft 33 also carries a dog` 33 which is keyed to this shaft so that when the dog face 37 is brought into contact with the dog 33 and the trunnion 7 is rotating this trunnion due to the eccentrically mounted i ent 34 will shift the arm 36 and in so ing this arm'will, of course, oscillate the shaft33 which in turn oscillates the eccentric y32. To throw the dog face. 37 into contact with' the dog 33 a hand lever 39 is provided which rides in aninclined slot 39 in the casing 27 and obviously as this lever is moved in this slot it causes the dog,r face 37 to move towardv and in contact with the dog 3S. J ust prior to the stopping` of the rotation of the washing cylinder 5 this lever 39 is shifted to effect this connection of the dog and then as the container rotates the roller 35 on the arm 36 coacts with the element 34; vand this arni is swung' outwardly by this element 34: to turn the cam 32 and apply the brake. The pa" ts are so positioned that the brake is only applied when the door opening A of the container will occupy a position facing the floor of the laundry when ejected from the casing` by the raising and lowering` mechanism to be now described.

lheferrinev to Figs. l, 9 and 10, it will be `observed that the brake operating` shaft 33 has rigidly secured thereto a crank arm 6G which in turn is connected with lever 13 by Vmeans of an .adjustable link 65. Thus it apparent'that when theshaft 33 is actuated by movement of the cylinder to apply the brake, the lever.13 will be operated through link 65 and crank arm 6G and consequently the drivingl motor will be deenergized. The lever 13 may be retained inshifted position by a detent mechanism if desired and accord .ingly l havelllustrated in 1 of the drawings a conventional form of toothed segment positioned adjacent the lever and with which any suitable form of detent carried by the lever may be employed.

It will he understood that before the raising' and lowering mechanism is placed in op.- erationV the rotation of the container or washing' cylinder' has ceased and'said cylinder has also been locked against further movement.

Y connected to a gearshifter 46. This shifter fn wint@ -p'b'sgelrved that the Washing' Cylinderisfsupp'or'ted in segments 40,- one ofthese segments being disposed atleach side ofthe machine. The-tr'unnions 7 ofthe 'Washing cylinder are mounted'directly on arms-of these segments. The segments are furthermoreA pivoted at 41to the sidevvalls ofthe y' ymachine'and each segmentat', its peripheryis .n provided with teeth 40'.' These segments coni stitut'e thev elevatingv andy 'supporting means .c

i 'i i lift this cylinder from the casing. To so lift the cylinder from the casing the operator first shifts the handle 43 Whichvis connected with a link 44 tola crank 45,', which crank is is mounted in bearings 47 It Will be understood that the shaft 12 and the lshaftA 16 are capable of a sliding movement for the purpose of coupling the gear 14 With either theV y gear 17 or the gear 18. VVhilethe shaft 12 rotates, the shaft 16 has no such movement,

the connection 15 permitting thefrotating .and non-rotating shaft to bercoupled Without im- Y parting thefrotationffrom one shafttothe other. Av shifter device 48 ismounted onra bracket connected With the machine and this y' eo.

devicehas a cam lWay 49 therein receiving a pin 50iixedly attached to the'sha'ft 16. Vhen ,Y .the operating lever 43 is shifted the rocking' movement imparted to vthe shaft 16 is converted-into a reciprocating movement'byr rea- Y son .of the cam Way just described, which movement shifts the shaft r12vvith its gear 14 into mesh `With the gear 18. vThis gearis rigidly attached to a sleeve 51 looselyv turneled gear 52 which meshes With'a gear 53 on the shaft 54, Which in turn carries a rspiral gear 55 that meshes With a gear 56 onthev f transverseshaft 23 extending across the back of the machine. This shaft 23 carriesat each end gears 58 Which mesh with intermediate gears 59ysuitably journaled in a housing 60 f and which intermediate gears in turn mesh With the gear teeth 40 on the Washing cylinder lifting segments. 'If the push button 61 is then kengaged current vWill be supplied toi the driving motor and throughthe connections 'herein described the lifting segments Willv be raised from the casing carrying with themthe Washing cylindeny I I'also provide the push button 62 to manually4 cut Voff the current ofthe motor. To'return the cylinder to the casinggthepush button 63 is operated, v1' 'which through a suit-'able reversingcontrol vfor the electric motor causesl the -rota'tionrof thek drivingmechanism' inf av reversing direction, which returns the Washing cylinderV to the casing. When it is so returnedcurrent to the motor is cut off by the push buttonv 62v and the lever 43 shifted to disengagethe gear 14 from the gear 18 by reason of themovement of the shafts 12'and'16. The rotation-control lever'l is then shifted,it being observed and, of, course, the motor driving vgear Y14 movedinto mesh With the cylinder operating v`to raise said cylinder.
