new, having siderable part in my previous applications Serial No. 694,899, filed February 25, 1924, which matured on August '7, 1934 into Patent No. 1,969,176, Serial No. 176,908, led March 21, 1927, which was abandoned on April 3, 1932, Serial No. 191,-

30, 1933 into Patent No. hereinafter referred to.

The particular objects of the present invention arel the provision of a combined washing machine t of the oscillating-dasher type Aand extractor of the centrifugal ty wherein the dasher is entirely disconnected from the driving mechanism during the rotatio-n of the extractor; the provicome apparent as the description proceeds.

In the drawings accompanying and forming a part of this application Fig. 1 is' a vertical sectional view through the center of a preferred 3 3 of Fig. 1 and looking downwardly; Fig. 4 is a horizontal sectional view corresponding to the broken line 4-4 of Fig. 2 and looking downward- 1y; Fig. 5 is a detail side elevation of a part of the 6 and 7 Fig. 8a shows certain lparts of said friction clutch; and Fig.`9 is a horizontal section on the line 9 9 of Fig. 7 and looking upwardly.

lis the vertical, hollow, bearing-sleeve 3 which projects above liquid level. Movably surrounding this sleeve is a second sleeve 4 having secured to its lower end the circular bottom 5 of the clothes separately from the. portion 5B and having its margin rigidly braced and secured to the bottom 5 in stiffening relation. w

Movably surrounding the sleeve 4 is a third sleeve I2 having at its lower end a circular disk cember 31, 1929, and which was on December 8,

having its upper end suitably formed, as by the flutes I3, for the reception of the sleeve I2 in supportedand operated relation, said sleeve being here provided with an internally-fiuted socket I3 for the purpose.

The sleeve 3 is supported by attachment to a hollow boss 20 carried by the supporting frame which will be described hereafter. Rotatably journaled on the exterior of said sleeve 3 beneath said boss is the hub 2| of a spiral gear 22 which meshes with a companion spiral gear 23 carried by the horizontal drive shaft 214. The position of the gear 22 is xed on the sleeve by means of a collar 25. Journaled in suitable bearings 30-33 carried by the frame is a vertical shaft 3| having at its upper end a spiral gear 32 meshing with a second spiral gear 33 carried by the shaft 24 and having at its lower end a crank 35 connected by a pitman 36 to an oscillatable, toothed member 31 pivoted on a vertical axis at 38.

Rigidly secured to the lower end of the shaft I1 is a pinion 40 adapted to mesh with the oscillatable member 31 whereby oscillating movement may be transmitted to the sleeve I2 so long as this meshing exists. Rigidly secured to the lower end of the hollow shaft I5 is the entering element 4I of a cone clutch, the complementary receiving portion of which is a hollow tapering flange 42 integral with and depending from the gear 22 whereby rotation may be transmitted to the container 8 so long as these clutch-members remain in contact.

Surrounding the shaft I1 is the bottom-plate 43 of a stirrup 44 having elevated sides 45 to which are articulated the upper ends of connecting links 46, whose lower ends are articulated to the forked arms 41 of a pedal lever 48 which is pivoted to the frame by a horizontal pin or shaft 49. A suitable thrust-bearing is interposed between the stirrup and the next adjacent part above the same, which in this case is the clutchmember 4|, the bearing being shown at 50. The

extremity of the lever 48 is provided with a corl rugated plate 5| for the operator-s foot, and near thereto a detent lever 52 is provided having a tooth 53 adapted to engage notches 54 in a stationary sector 55 thus enabling the parts to be retained in selected position.

An electric motor 60 having its armature shaft 6I horizontal is pivotally suspended from a horizontal pivot-rod 62 carried" by the frame, the rod and shaft being parallel tothe shaft 24 and to each other. Motion is transmitted between the shafts by a belt 63 applied to pulleys with which said shafts are provided, the motor being kept tight by means of a spring 64 applied to a portion of said motor remote from the rod 62 and adjustably tightened by a nut 65 and a threaded rod 65* carried by the motor.

The operation of the device thus far described 4 is as follows: the clothing to be washed is placed in the container 8 and detergentliquid added to a level preferably between a and b shown in Fig. 1. With the parts occupying the position shown in Fig. l, the operation of the motor causes Ian oscillatory movement of the sleeve I2 its blades I4, setting up vigorous currents inside the contaner in the direction shown by the arrows. This agitation loosens the dirt from 1the clothing and this dirt, together with the scum .is largely expelled through the apertures in the sides and to the bottom of the container where they are entrapped, the grit settling to the bottom and the' scum collecting in the annular space outside the wall 1. During this part of the ctionthe container has been free to rotate but does not so rotate unless accidentally something becomes caught between it and the dasher.' When the washing operation has continued to a sufficient extent the pedal is depressed bringing the parts into the position shown in Fig. 2. This disengages the pinion 40 from the oscillating member 3l and brings it into engagement with'a spring .68 carried by one of the bearings 30 whereby it is held stationary; although it is likewise possible to omit the spring in which event the dasher will either revolve or remain atrest in accordance with the comparative friction effec Upon engagement of the two parts of the friction clutch the container is gradually brought to a high speed of rotation in order to extract adherent liquid centrifugally. Elevation of the clutch member 42 under the inuenceof member 4| is opposed by a thrust bearing 66 and spring 81 which thus produces a predetermined driving effect.

Partly as a safety measure, and partly to reduce 'the cost of the casing, the latter is terminated by a rim 10 located at such level as to be overtopped by at least part of the apertures of the container when said container is elevated, ,25

thus necessitating the employment of the removable splash-band 1 I. Preferably this band is provided with inwardly-turned rim 12 loosely receiving the rim 3 of the container and preventing the operator from touching the same while rotating. This, combined with the disconnection of the dasher, renders it safe to use the extractorwithout any cover, although a cover 13 is preferably provided to prevent splashing during the washing operation and the same may be left on during the extraction if desired. This splashband is described and claimed in my application Serial Number 342,520 above mentioned.

In Figs. 6, '1, 8 and 9 of this application I have shown the machine illustrated and claimed in my application Serial Number 694,899` above mentioned. This machine comprises a casing having a side wall I* and bottom wall 2*, supported on a suitable frame and having a vertical central.

. apertures 83 near the top thereof, although the lower part is substantially imperforate to prevent the escape of liquid. Above the apertures an inwardly-tapering safety-guard 1* is provided. Carried by the upper end of the shaft I1* is the oscillatable-dasher I2* terminating about its lower end in a downwardly-flaring conical disk I3* which closely overiies the flaring bottom of the container and formed on its exterior with dasher blades |4*. l

The sleeve 3* is su 4ported by attachment to a hollow neck 20* carried by the supporting frame, and rotatably journaled on the shaft I1* beneath said sleeve is the hub 2|* of a spiral gear 22'L which meshes with companion spiral gear 23* carried by the horizontal drive-shaft 24*. Journaled to they frame on a level with the gear. 22* is a spiral gear 33* connected by a pitman 36* to an osoillatable toothed member 31* pivoted on a I Acontainer is illled with |11l is a pinion 40 adapted to mesh with the oscillatable member 31?, and rigidly secured to the lower end of the hollow shaft I5 may be the radially-slotted plate 8|I bymeans of which motion is transmitted to said sleeve from the pinion 22a through the friction disk clutch shown limited degree of friction for this duced by some coiled springs 90 interposed between the gear 22a and the nearest disk, these being located in apertures formed for the purpose in a ange 9| carried by said hub. Motion of the plate 88 is transmitted to the plate 8| by means of a nger 93 carried by the one and engaging the slots of the other.

Carried by the lower end of the shaft |'|=1 is a thrust-bearing 50a which rests on a stirrup44a, one end of which is pivoted at 95 to a' frame member and the other end of which is articulated at 96 to a link whose upper end is attached to an arm 91 carried by a rock-shaft 98 provided with a hand-lever 99. In one position of said hand-l lever the gear 4|)a meshes with the oscillating member 3la producing oscillatory movement of the shaft Ila and the dasher the pin 93 the containeris at rest.

In the other position of this lever the gear 40a at will, ldepending only upon the friction between the two shafts and their related parts. 'I'he only substantial difference between the two machines is that in the washing liquid by lowering it into the liquid, while in the second device filling is accomplished by raising the liquid. For this purpose I have shown the hub 4a as formed with vertical flow-openings and the sleeve 3*i as surrounded by a conduit |0| communicating therewith. Located at one end of the motor 60a is a centrifugal pump |02 whose inlet is connected by a pipe |03 with the bottom of the casing and whose outlet is connected by a pipe |04 with the conduit |0|. In this Way, a continuous overflowing of liquid from the container 8a is pro-- duced during the time that the mechanism is being driven by said motor through the belt 63a.

'I'he supporting frame of the first described device is preferably made of three vertical channel members ||0 rigidly secured at top and bottom to horizontal angle-irons the parts being spot-welded together tornake a Ilight and rigid whole. Three of these -uprights are preferably panels' ||3 by which H8, which overlaps the fans purpose S plO- being meanwhile disengaged so that rst described device the4 3 employed, the 'side flanges 2 of the uprights being flared atan angle of 60. The sides of the frame are then covered by flat sheet-metal the mechanism is hidden, that panel which constitutes the front of the housing being stamped out as shown at ||4 1n tical slot to permit the pedal movement.

However, a vertical cornered castors 1; and over each corner of the housing I attach a hollow slanting sheet-metal sham of thepanels ||3 and affords a., finished appearance at minimum cost. The lower margins of the panels ||3 are extended vbeyond the uprights so as to prevent top of the housing is surrounded by a circular sheet-metal hoop |20 provided with a narrow skirt 2| hiding the top of the housing ers |24. The bearings 30 are most conveniently carried by a bracket |25 secured to that upright ||0 which is opposite the pedal.
