wnsnmo MACHINE.

Original No. 1,493,987, dated May 13, 1924, Serial No. 642,607, filed May 31, 1928. 'Application for reissue filed December 13, 1924. Serial No. 755,802. 4

To all whom it may concern: Be it known that I, JOHN E. KE NEY, a citizen of the United States, and resident of Portland, county of Multnomah, State of Oregon, have invented a certain new and useful Improvement in Washing Machines, of which the following is aspecification.

My invention relates specifically to washing machines which do not necessarily include a tub, but which are adapted to be' mounted on any suitable tub.

My invention in further particulars relates to washing machines of the dolly-head type that is which comprise a rocking or oscillating head provided with pendant prongs or fingers by which the clothes are engaged and agitated in the washing liquid. It has been attempted heretofore to make said dolly head and its pendant fingers hollow, and to install a pump element in the'dolly head or its pendant fingers. But with such arrangement, the water was alternately sucked into and then ejected again from said fingers. Such action tended to subject the clothes to undue wear, since when the pump exerted its suction action it tended to pull the clothes into the orifices of the fingers. Besides, the resistance offered to the pump action, while said orifices were covered by the clothes during the suction stroke of the pump, tended to impose undue work on the latter.

The object of my invention is to provlde a washin machine of the character referred to in w ich said undesirable detrimental features are eliminated. I

I attain my object by providing a hollow head and providing the latter with hollow pendant fingers, through which streams'of the washing liquid are continuously ejected by the operation of a pump element located outside of the washing liquid preferably mounted on the cover of thetub. "In this way, the washing 0 eration is facilitated by less spread out, that is to say, prevents it from wadding up, which would tend to keep portions of the clothes out of contact a with the washing liquid.

A further improvement of my invention has for its purpose the simplification of the devices operating the pump and simultaneously rocking the agitating head. The above mentioned and incidental features are hereinafter fully described and are illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of my device mounted on a hinged base and shows the pump and connecting mechanism in section 1, taken approximately on a line of 1- -1 of Fig. 2'.

Fig. 2, is a section taken on a line 2-2 of Fig. 1 and shows by arrows the approximate flow of water through. the machine.

Fig. 2 is a View showing detail of construction.

Fig. 3, is a view taken on the line 33 of Fig. 2 and shows in dotted lines the approximate position of the oscillatible washing head.

Fig. 4, is a section taken on the line 4-4 of Fig. 3' and the arrows showing the approximate circulation of thewater through the tub.

My device is mounted on a portable base, which is made of a plurality of pieces. The portion 1' is clamped to the tub 29 at one side, and the portions 1 and 1 are hingedly attached thereto. The washing mechanism is mounted on the base 1" which covers the major portion of the top of the tub and the portion 1 covers substantially the remainder. There is no mechanism mounted on section 1 and thus it can be readily raised upward and thus provide easyi access into the tub without lifting the mechanism. A prime mover, as the motor 2, is mounted on the base 1 and rotates the shaft 3. Another shaft 4 is held in axial alinemcnt with the shaft 3 and is releasably connected thereto by means of a clutch 5. The male half 5 of the clutch is fixed to the shaft 3 and the female half 5 is slidably attached to the shaft 4 but is/kcyed against difi'erentialrotation therewith. A clutch lever 6 pivoted to the frame 7 of the mechanism, moves this clutch member 5 into and out of operative connection with the member 5*. A worm 8 is mounted on the shaft 4 and meshes with the worm gear 9 which'is mounted on vertical throu h the suction pipe 15 and force it up' into the pipe 16. An arm 17 is mounted on the end of the shaft 10 and has a pin 18 affixed near its end, the pin and arm formin a crank. The connecting rod.l9 is connectet with this pin on one end and to the crank arm 20 on its opposite end, thus the rotationof the shaft 10 causes the oscillation of the crank 20. Crank 2() is integral with the hollow-stub shaft 21, which is 'journaled in the tab to 1. I provide a plate 22 covering a relative y large port-ion of this cover, on

vwhich this stub shaft and crank bears so that wear may be reduced to the minimum. The oscillating washing head 23 is provided with a hollow shank 23 which is connected to the said stub shaft 21 by means of pin The washing head is also hollow and is provided with a number of hollow prongs 25 which are perforated as 26. The pipe 16 extends into the hollow stub shaft 2-1 and the connection is made watertight by means .of packing27 which is held in place by a packlug nut 28. Water is thus forced into the washing head and it escapes through the perforations 26. The supply of water for the pump 14 is obtained through the inlet pipe 15, which has perforations as 15. The suction pipe 15 lies closely along the side of the tub and the perforations 15 are preferably arranged on the inner face of this pipe so they will not be readily clogged by the clothes in the tub, thus a plentiful supply of water can always be assured for the pump. As shown in Fig. 2", prongs 25 for my device may be made with removableends, as 25 which may be screwed into the end of the prong 25 at a point as 25. Thus the hollow washing head and its prongs may be cleaned readily.

The jets of liquid emitted from the dolly head should have sufiicient force to exercise a substantial repelling efiect upon the clothmg. The mere ejection of these jets without impingin or repelling force would have no apprecialfie effect in removing" said clothes from the engaging ortions of the dolly head. The jets would merely supply a flow of washing liquid to the clothes at the point at which they are gripped. The ejecting of said jets into the clothes without a mechanical device for oscillating, as opposed to completely rotating the doll or stirrer head, would also be ineffective ecause the clothes would not tend to change their relationships relatively to the member emittin said jets and thus said jets would affect on y one portion of the clothes. If a device were used that rotated continuously the clothes would be firmly gripped by said device and the thus being gripped in one portion only would become w-added up and thus only a. portion of the clothes would be washing by being dragged, by the fingers, through the washing liquid until said clothes were either pulled off or torn off. The same difficulty is present in oscillating dolly type washers, but in a lesser degree, where the jets of washing liquid are not present inasmuch as the clothes often are not'rcleased at the point of reciprocation. I have discovered that if jets of washing liquid are directed against the clothes along said fingers with sufficient force, however, the clothes will be removed from the dolly head each time said dolly hcad changes its direction of rotation.

\Vhile the drawings show the devices employed by me to be arranged so as to operate with a circulatory effect, that is. the pump initia'ly drawing the washing liquid from the tub, ejecting it into the clothes, and then drawing the liquid back into the pump for a.

second cycle, and continuing such circulatory action, it may be found that if my invention is used for a larger scale of work,

for example, in a laundry, that it would be undesirable to recirculate the same washing liquid or water over and over, because the liquid may soon be too polluted for circulation through the clothes belonging to different customers. For laundry use, especialiy, the washing liquid had better be discharged from the container through which the water' flows, or is driven, in its passage from the dolly head, after it has been used a single time.

The operation of my device is as follows:

Power is obtained from the motor 2 which rotates the shaft 3, the shaft 4 can be connected so as to rotate therewith by forcing in the clutch 5. The shaft 4 in rotating not only transmits power through the speed reduction gears, but also actuates the pump which causes water to flow through the device. The rotation of the worm 8 causes the rotation of the worm gear 9 which rotates the shaft 10 and thus .the crankarm 17.

The rotation of the crank arm 17 and its pin 18 causes the longitudinal and angular movement of the connecting rod 19. The arm 20 is slightly longer than the crank arm 17 and-thus the rotation of the shaft 10 causes only partial oscillating rotation of the stub shaft 21. The-washing head is thus oscillated back and forth. The rotation of the pump causes water to be drawn in through the perforations 15 in the pipe 15 and forces the water through the pipe 16 into the hollow washing head 23 and through the perforation 26 and thus through the clothes in the tub.
