Figure 9 is a plan view of a modi?ed form of agitator and driving mechanism; and Figure 10 is a sectional view taken on line Ill-I0 of Figure 9. 45 In Figure 1, I have illustrated a form of my invention as applied to a two-tub washing and extracting machine. The machine illustrated comprises a washer tub or casing l and an ex tractor tub or casing 2. These elements of the machine are carried on a suitable frame or base member ,3, supported by legs 4 having casters 5, provided for the purpose of facilitating the mov ing of the machine. The washer tub is secured to the frame member 3 by means of a number 55 2 2,105,218 of bolts 6 circumferentially spaced about the bottom of the tub at points adjacen to the outer edgeihereof. The extractor ca g 2 is secured to the base 3 in a similar manner by means of bolts ‘I. The extractor casing 2 is provided with an apertured top-plate 8 which provides a clothes chute as between the adjoining parts of the tub I and casing 2. The plate 8 is ?tted snugly over the top of the casing 2 and is secured to the tub 10 I by the bolts 9. Within the extractor casing 2 there is provided a rotatable container in hav This clutch is of the friction cone type and it has ing perforations II whereby adherent water may be removed from fabric articles during the cen through a slot 42 formed in the bushing 38. The lower end of the bushing 38 is formed with trifugal extracting operation. a shoulder or collar 43. 15 - An agitating device comprising a base-member I2 of spherical contour and having vanes I3, is provided for agitating the liquid contents of the washer tub or casing I. The base-member I2 is closely ?tted over a hollow shield I4 of spherical 20 contour within which certain parts of the driving‘ mechanism for the agitating member are housed. The agitating device is driven with a combined gyratory and rotational movement. The driving of the agitator is effected through a rotatable agitator-driving shaft I5 to which is rigidly amxed a bracket I6 carrying an angular crank I1 which is in the form of a stub shaft ?xedly se cured to the bracket I6. The bracket I6 is preferably in the form of a 30 die casting and is cast about the shafts I5 and I1 so that these three elements form an integral unit. The base-member I2 is provided with a central bearing portion I8 within which the shaft I ‘I is rotatably journaled. The base-member I2 35 is secured in place on the shaft H by means of a washer I9 and a screw 28, the screw engaging the shaft I1 and the washer I9 overlapping and en gaging the countersunk central portion of the member 12. A gear 2| is secured in threaded engagement 40 to the underside of the base-member I2 in align ment with the axis of this member. The gear 2| meshes with a ?xed or stationary internal gear 22 threadably secured to the bearing member 23 45 of the shaft I5. The outer edge of the internal gear is extended in the form of an annular plate 24 and it carries at its outer edge the spherical shield member I4. The bearing member 23 co operates with the internal gear 22 and with suit 60 able gaskets 25 in sealing the opening provided in a driving cone 31, the outer edge of which is ?xedly secured to the enlarged driving pulley 32 and the center of which is formed with a bearing surface. The cone 3‘! is rotatably mounted on a bushing 38. A driven conical clutch member 39, faced with a suitable friction material 40, coop erates with the driving clutch member 31 in con trolling operation of the agitator shaft. The driven clutch member 39 is ?xedly secured to the 10 shaft I5 by means of a set screw 4|, which passes A cup-shaped member 44 having a ?anged rim is secured by any suitable means such as the screw 45 to the lower end of the shaft I 5. A coil spring 46 is held in com pression between the cup-shaped member 44 and a washer 41 which abuts against the shoulder 43 of the bushing 38. The upper end of the bushing 20 38 abuts against a washer 48. The washer 48 in turn is pressed against the lower end of a sleeve 49 and is held in such position by reason of the force exerted by the spring 46. A slanting slot 50 is formed in the sleeve 49 for bearing member 23. An operating handle 52 is ?xed to the sleeve 49. When the operating handle 52 is angularly shifted in one direction or the other the inclined slot 50, working on the bolt 30 5| serves to raise or lower the sleeve member 49 and in doing so it axially shifts the bushing 38 and the driving clutch member 31, thus connect ing or disconnecting the clutch members 31 and 39 with each other as the case may be. This ar rangement provides a simple and inexpensive form of clutch device. Suitable packing means 54 are provided in the centrally enlarged lower portion 53 of the bearing member \23. The packing material 54 carried at 40 this point is pressed in sealing relation about the shaft I5 by means of a slidably‘r?tted gland 55 and a spring 56, the latter being pressed against the gland by means of an apertured nut 5‘! thread edly engaging the lowermost end of the bearing member 23. In Figure 3 the clutch is shown in its disengaged position and in Figure 5 the clutch is shown in its engaged or driving position. In such positions of the clutch and the sleeve 49, the stud 5| is the bottom of the tub I for the reception of the received in one or the other of the horizontal end agitator driving mechanism. portions of the slanting slot 50. When the clutch is in the position shown in Figure 5 and the motor is operating. the shaft I5 and the angular crank An electric motor 26 is provided to drive the washing and extracting mechanism. A belt 21 65 provides a direct driving connection between the motor and the extractor container ID, the pump 28 and the adjustable idler pulley 29. The idler pulley carries a small pulley 30 for driving a sec ond belt‘ 3|, which in turn serves to drive an en 60 larged pulley 32 for driving the washing mech anism. ' The washing and extracting mechanisms are provided with suitable clutches whereby these parts of the machine may be connected or dis 65 connected selectively in driving relation to the electric motor. The pump 28 is continuously driven, having at its inlet side an open communi cating connection 33 with the extractor casing 2 and a valve-controlled communicating connec 70 tion 34 with the washer tub. The outlet side of the pump is connected in communicating rela tion with one end of a hose 35 which terminates at its other end in a swiveled gooseneck 36. The washing mechanism is controlled by means 76 of the clutch illustrated in Figures 3, 4, and 5. Cl receiving a bolt or stud 5| ?xedly carried by the I‘! are continuously rotated in one direction thereby causing the agitating member I2 to gyrate about the axis of the shaft I5 after the manner of a gyrostatic pendulum or a spinning top having the tip of its peg in a conical hole. The center of the agitating member thus de 60 scribes a circular path in a direction correspond ing to the direction of rotation of the shaft I5. Due to the fact that the internal gear 22 is larger than the gear 2|, a rotational movement of greater angular velocity and reversely to that of the shaft I5 is imparted to the agitating mem ber I2. The motion of the vanes 0r blades I3 of the agitator thus is the resultant of the two circular motions or compound movement of the agitator. The speed of rotation of the agitating mem ber as compared with that of the shaft I5 may be decreased by either making the internal gear 22 smaller or by increasing the size of the ex 70 ternal gear 2| and similarly if it is desired to 75 ,3 2,105,218 prevent any rotational movement of the member” l2 about its own axis, the gears 2i and 2! would be both of the same size. Thus by varying the relative'size of the gears 2| and 22 the agitator CR can be made to rotate faster or slower about its axis or such relative rotationalmovement may be suppressed entirely if so desired. provides a bearing pin for the idler pulley. The plate member 61 is provided with an apertured up-turned portion 1| through which an adjust ging rod 12 extends. , With the parts as shown, the base-member I2 is driven with a gyratory motion in one direction 10 about the axis of the shaft I5 and with a rota tional motion in a reverse dire?mv about the axis of the anguliiacrank H. Due to the com pound motion imparted to this member the blades l3 of the agitator will sweep back and forth about the central region of the tub in such manner . - The rod 12 is threaded ,at its opposite end and is adjustably received in a threaded member 13 swiveled on the plate 65. A spring 14 abuts against the plate member ‘H at one end and at its other end it engages the rod 12. A knurled provided on the end of or loosening the tension this manner tightening a washer 15 carried by operating handle 16 is 10 this rod for tightening of the spring 14 and in and loosening the ten and then outwardly and downwardly and then sion of the belts 21 and 3|. The plate 66 is freely movable about the rivet 68 and this arrangement permits su?icient oscillation of the pulley about such point so as to equalize the tension between the belts 3| and 21. The plate 65 also serves as inwardly back to the agitator with a movement a support for the motor 26 which is secured so as to cause a violently pulsating circulation of the water upwardly from the center of the tub similar to that described by the particles of a‘ thereto by studs 84. circular vortex ring about the axis of the vortex In the modi?ed form of agitating mechanism ?lament. shown in Figures 9 and 10 the agitator member The washing action accomplished by my im 11 is rotatably mounted upon a vertical crank 18 proved form of agitator is somewhat similar ?xed to turn with an agitator drive shaft 19. The agitating member 11 is provided with a plu though in a reverse direction to that accom plished by the reversely rotating so-called gyrator rality of vanes 8|] and it has a base member 8|, type of washing machine with the difference, the same being in the’shape of a hollow inverted however, that such machines require complicated dished member which serves to provide a support and power-consuming reversing mechanism, for a gear 82 operatively associated with an in whereas the same object is accomplished in my ternal stationary gear 83. This arrangement operates in much the same improved construction by the combination of the gyratory and rotary motions‘ imparted to the manner as does the mechanism shown in Figure 1 agitating member. By reason of this arrange with the difference, however, that the agitator ment the machine operates very smoothly and gyrates in a horizontal plane as will be evident quietly and requires considerably less power to from a consideration of the drawings. Thus operate than would be necessary if some of the when the shaft 19 is‘ rotated the agitator is parts were reciprocated or alternately-reversely gyrated about an axis of the shaft ‘I9v and at operated. \ the same time by reason of the relative size of A clutch member 58 of similar construction the gears 82 and 83 it is given a‘rotational 40 to the washer mechanism clutch just described motion in a direction reverse to the direction of ’ is provided for controlling the operation of the its gyratory movement. The operation of the machine is a very simple extractor container l8. A suitable control han dle 59 is provided for effecting the engagement matter. To begin with the tub I is ?lled with and disengagement of this clutch. The pump clothes and a detergent liquid or soap solution. 28 is provided with a suitable control valve hav ing an operating handle 60 for connecting and disconnecting the pump to the washer tub. As previously stated the pump is in continuous com munication with the extractor tub 2 and the out 50 let side of the pump is in constant communica tion with the hose 35. The gooseneck 36 of the hose 35 is arranged for reception in either of the openings 6| or 62 formed in a recess in the top of the extractor Cl CA top plate 8. The opening 6| communicates with a drain hose 63, whereas the opening 62 com municates with a side opening 64 formed in the upper part of the wall of the washer tub. By this simple expedient the water drained from either the washer tub or the extractor tub can bedi rected to a, suitable drain or returned to the washer tub. This arrangement provides a very convenient method of handling waste water from the machine or for returning usable soapy water from the extractor casing to the washer tub and it at the same time prevents spilling and splash ing water about the ?oor in the room where the machine is used as the hose 63 empties into a suitable drain or receptacle. The idler pulley 29 is slidably mounted upon a plate 65 and is secured thereto by means of a lower and an upper'plate 66 and 61 secured to gether by means of a -rivet 68 which is slidably " ?tted in a. slot 69 formed in the plate 65. The 75 plate 66 has secured to it a stub shaft 10, which 71) 20 30 35 40 The control lever 52 is shifted to the “on” posi 45 tion after the motor 26 has been started and after a few minutes of agitation the operation of the agitator is stopped, and the clothes are transferred to the extractor casing Ill. The ex tractor control lever 59 is then moved to the “on” position and in a short time the centrifuge will have extracted most of the water from the clothes whereupon the centrifuge is stopped and the clothes removed therefrom. The clothes are next rinsed either by adding 55 clean water to the extractor while stationary or rotating or by transferring them to a tub full of rinsing water after which operation the clothes are returned to the extractor for the ?nal drying operation. During the initial extracting opera 60 tion the soapy w ter can be returned to the tub I by connecting he gooseneck 36 to the hole 62 and during the second extracting operation the rinse water can be conveyed to a drain by con necting the gooseneck to the hole 6i. When the 65 washing is ?nished the valve member 68 is shifted to open valve position and contents of the tub I are pumped to a drain. Furthermore it is to be understood that the particular forms of apparatus shown and de-» 70 scribed, and the particular procedure set forth are presented for purposes of explanation and that various modi?cations of said apparatus and pro cedure can be made without departing from my invention as described in the appended claims. 75 4 2,105,218 Having thus described my invention what I claim is: 1.
