, sembly and Fig. 11 is a plan of the sleeve shown in ferring to said drawings, which illustrate a simple embodiment of the present invention, the referencecharacter 12 designates the supporting frame of the machine,

which frame may comprise upright frame members 13 connected to horizontal frame members, such as rings or bands, 14 andv 15, so as vto provide a rigid and substantial supporting frame for the mechanism of the machine. The frame members are preferably composed ofl channel formation in order to obtain strength and lightness. Supported upon the horizontal frame member 14 isl the tub 16 in which is contained the 'clothes agitating devices, here shown as comprising an agitator 17,- located adjacent the bottomv of the tub and a dolly 18 positioned above .the agitator. The dolly and agitator are mounted on a dolly shaft 48,

located below the tub and driven from an electric or other motor 19, which may be supported on a bracket 19a mounted on the frame-work of the machine? f The transmission gearing is contained within a gear case 20 preferably composed of a'n upper 22 bolted or otherwise secured together along oscillated by novel transmission gearing section 21 and a lower section case is supported by chine, and, a's shown, standing lugs or it is provided with upl or otherwise secured to the band or ring 14, and the lugs 24 being bolted or otherwise secured to a-brace bar 25 which is secured to the band or ring 14'. The ogear case lies lin a hori'zontalplane and contains "the, transmissiont'gearing, the shafts. of

which extend in vertical line, while the gear wheels and other power transmitting elements lie in and move in horizontal planes,

the' frame ofthe mabrackets 23'and 24, the lug i whereby the use of mitered'or beveled gears 'Referringx now to illustrate t e transmission gearing in detail, it will be seen to comprise, among` other things, a spur gear wheel 26 having a vertical stud shaft 27 secured thereto and journaled in a bearing formed in a boss 28 on the lower side of the lower gear case section 22. The spur gear wheel 26 is preferably formed with a hub portion which is contained in a recess in the gear` case and rests on the bottom of said recess. Y

Meshing with the spur gear wheel 26 is a spur pinion 29 which is pinned to a short vertical shaft 30 journaled in bosses formed .in the upper and lower gear case sections.

.The shaft 30 protrudes from the upper gear case section, and upon the protruding end is pinned or otherwise secured a belt pulley 31 over which is trained a belt 32 which runs to a belt pulley 33 secured on the vertical shaft of tlg. motor 19. The spur gear wheel 26' and pinion 29 arepreferably contained in the lower` section of the gear case, and directly above said spur gear wheel and pinion is a rocker arm or oscillating arm 34 which, as shown, is fulcrumed upon an axis concentric with the axis of thewringer driving shaft shown at 35. Said wringer drivingv shaft extends in' a vertical direction along the side ofthe tub and is provided at itsl upper end with, suitable gearing (not shown)l for operating the wringer, but inasmuch as said wringer driving gearing forms no part of then present invention, itv has not 'been illustrated.

A horizontal spur gear wheel 36 is -provided for rotating the wringer driving shaft 35, and said spur gear wheelpintermeshes with the spur gear Wheel 26,. The spur gear 4wheel 36 has a`I vertical, downwardly exvtending stud shaft 37 secured to it, which is' the Xing sha journaled in a boss 38 formed on the lower section 22 and on the upper side of thev spur gear -wheel it is formed with an upstanding hub portion 39 which is journaled in a boss -on the upper gear case section. `The hub portion 39 acts as the fulcrum 'for the rocker arm-34 which is apertured at one end to receive the hub portion. Suitable driving connections are provided between the hubA of the spur gear Wheel 36 and wringer driv- 35, and, as shown,` said connections comprise a clutch pin `40 secured in the wringer driving shaft 35 and entering fin notches formed in the upper end of the hub portion 39. A sleeve or casing 41 is/secured in the boss on the upper gearfcase section and extends up tothe housing (not shown) for' gears of .the wringer mechanism. T e rocker arm 34 rests upon the spur gear wheels 26 and 36, and horizontal plane, and means are provided `for oscillating said rocker arm, which means, as shown, comprise a wrist pin 42 secured 1n the hub portions 43 of the spur gear wheel 26 and traveling in a slot 44 formed in the rocker arm 34. As a preference, a slide oscilla-tes in .a i

block 45 is provded upon the wrist pin Aand u slides in the slot of the rocker arm. Upon the free end of the rocker arm is`a gear segment 46 which meshes with a spur pinion 47, loosely mounted upon the doll shaft 48 which is journaled in a boss 49 ormed on the lower gear case section 22.

The spur pinion 47 and dolly shaft 48 are provided with lco-acting clutch jaws 50 and 5l, whereby the pinion and dolly shaft may `be clutched together or unclutched from shaft'48. As illustratedv in the drawings, the

lower end of the lsleeve is formed with a shouldered portion 56 and with a threaded npart 57 which screws into a threaded opening in the uppervend of thehousing 54. The bottom 58 of the tub is secured between the shoulder 56 of the sleeve 55 and the upper end of the housing 54, and gaskets 59 are provided between the tub bottom 58, the shoulder 56 and the housing 54 tornake a leak proof joint at this point. An outwardly opening chamber 60 is formed in the housing 54 below the lower e'nd of the threaded 1-00 part 57 ofthe sleeve 55, and in 'said cham .ber is a cone shaped disky 61 of rubber ory ,the like, whichA disk fits snugly Vupon the dolly shaft 48 and acts to shed `any waterl trickling down along the dolly shaft, away fromthe mechanismsbelow the disk.

Rotatably mounted upon the bearing sleeve 55 is a supporting member 62 for the dolly andy agitator,` here shown in the form f of a sleeve projecting `above the bearing sleeve 55 and having its upper end pinned or otherwise secured to the upper end of the dolly shaft 48, wherebythe oscillatory'1 movements of the dolly shaft are imparted to said supporting member 62. The agitator17 is removably mounted upon the supportingmember 62. As shown, the supporting member 62 is formed at its lower end with a shoulder-63 upon which the agita` r tor rests, andL the' supportingglnember is formed with a plurality of grooves 64 in its face that are adapted to recelve lugsv or other projectionsA 65. formed on the agitator, whereby the latter is. connected to the'vagitator supporting member 'sd as to oscillate therewith,vbutjcapable of beingreadily removed therefrom by. lifting it up above the doll shaft. l

v T e agitator is of novel.construction.` It it composed of a. flaring or bell shaped body portion, the lowery marginal edge portion underside of the flaringor bell shaped partof the agitator is formed a downwardly projecting sleeve or collar 67 which also' sur.-

rounds the agitator supporting member,`

both of said sleeves forming a long bearing or connection between the agitator and its supporting member, thereby preventingany tendency for the agitator to tilt upon its` support.

0n the upper face of the body portion of the agitator are radial ribs 68, which by preference upstand only slightly and merge into the face thereof at places -adjaceht its upper end. Said ribs' which engage the clothes cooperate with a dolly, presently to be described, in propelling them back and forth in the tub during the washing operation.` It will be understood that the clothes, which are being washed, rest in part upon the agitator so as to be carried by it back and forth, around the interior of the tub.

rllhe walls ofthe body portion, sleeves and ribs may be formed of relatively thin, light weight material, such as aluminum, if desired.

Associated with the agitator is the dolly 18, which is also removably held on'the agitator supporting member 62. As shown, thedolly has a concavo-conveX, or dished disklike body -portion 69 which extends from a' central hub portion 70 that surrounds the agitator supporting member and is formed with lugs or ton ues 71 which engage in the grooves 64 o 'the agitator supporting member. On the lower convex side of the `dolly are downwardly projecting radial lugs 72 which engage with the clothes and act to propel them back and forth in the interior of the tub. lf desired, the lugs may be cast hollow, as shown, for the sake of lightness, and a number of apertures 73 are formed in thebodyof the dolly to permit water to pass through the same.- The dolly ma be formed of cast light weight material suc as aluminumyifdesired. i

Conveniently, one orr more knobs 74 are secured to the'disk-like portion of the dolly and furnish' means whereby the same may be handled in placing it upon'the agitator fsupporting member or removing it there- .'from, or 1n casevlt V1s vdesired to turn the dolly and agitator manually. llt-is to be l understoodv thatmthe' dollyy is slidably conlnected with the agitator supporting member andis free to move up and down thereon. Fig. 8 of the .drawings showsthe dolly as suspended, which is a position occupied by it`when resting upon a batch of clothes contained. in the tub. When placingclothes in the washing machine or 'removing them therefrom, the dolly may bey'` disconnected from the agitating supportingmember and afterwards replaced, When clothes are contained in the tub the dolly rests upon the clothes, but when the clothes are removed it rests upon, the upper end of the agitator.

From the above it will/be observed that thermore, the arrangement of the verticall shafts permits the motor shaft to extend vertically which is of particular importance. By arranging the fulcrum of the rocker arm concentric with thev wringer ldriving shaft, a relatively long rocker arm is obtained, and by placing the rocker arm actuating wrist pin intermediate the ends of the rocker arm a long sweep is given to the Arocker` arm with a very steady and even motion. With the long sweep of the rocker arm, the dolly and agitator are moved through the greater part of a complete circle.

lt is also to be observed that by `reason of the novel disposition of the power transmitting elements, the oscillatory member thereof is operatively connected to the dolly shaft without the interposition ofany bevel o r miter gears and one of the continuously rotating power transmitting members is op erativelyl connected` to the wringer driving shaft without the interposition of any bevel or miter gears. 'The novel dolly shaft. assembly enables the parts tobe readily assembled in constructing theV machine and permits theA ready removalv and replacement of the dolly and agitator. The bell shaped or flaring agitator, while acting asl a support for the clothes, prevents them from becoming tangled around the dolly shaft. lf

desired, however, the agitator may be dispensed with, in which case, the clothes rest upon the bottom of they tub. The dolly `being freely mounted upon ythe supporting sleeve,

it`rests uponV the clothes during the washing operation and the depending lugs thereof yenter among the clothes and carry them around back and forth through the water duced speed. yAs the spurA gear wheel 26 rotates, the wrist pin 42 is rotated in the slot 44 of the rocker arm .34,.and, as a consequence, the rocker arm is oscillated, thereby.

imparting a rotary reciprocatory or oscillatory movement to the spur pinion 47. Inasmuch as the spur gear wheel 36 for the wringer driving, shaft 35 intermeshes with ne. A

ila

the spur gear wheel 26, the wringer .driving shaft is continuously rotated during the operation of the transmission gearing. By

properly shifting the clutch lever 53, the

dolly shaft 48 may be clutched to the spur `v pinion 47 or unclutched therefrom as desired, and, in this way, the operation ofthe agitator and dolly may be controlled.

It will be observed that the clothes are supported, at least in part, by the agitator and that the dolly rests upon and engages with the clothes. The agitation of the clothes is accomplished by the dolly with the clothes resting upon the agitator. The clothes, being conined between the agitator y .and dolly, are carried back and forth through the water in the tub, whereby a very thorough washing action is obtained on the' clothes. Furthermore, this arrangement prevents the clothes from being tangled and also provides means for agitating the clothes throughout the depth of the tub, since the agitator co-operates with the dolly in swinging the clothes back and forth in the tub. By the term agitator, wherever used in )the specification and claims, is meant a ysupport for the clothes operatively connected With the dolly shaft so asto rotate therewith. f

More or less variation 4of the exact details of construtcion is possible without departing from the spirit `of this invention; We desire, therefore, not to limit ourselvesV to the exact form of the constructionfshown and described, but intend, in the following claims, to point out all ofthe invention disclosed herein.
