Referring to the complete washing machine 15 illustrated in Figure 1, the numeral I indicates a washer tub which is provided for the purpose of receiving clothes and other articles to be washed. Beside the washer tub, there is positioned an extractor tub 2, in which adherent liquid is separated from the clothes after they havebeen washed or rinsed. The tubs I and 2 may be formed from steel stampings and finished with a coating of vitreous enamel.

The washing operation is eiiected by means of an oscillatable dasher or agitator 3, which extends upwardly from the bottom of the washer tub I, and which is mounted for movement about a vertical axis. The agitator 3, is driven by a motor 4, which is supported beneath the washing compartment I, and it is connected in driving relation to the agitator 3 through suitable gearing carried in a gear casex5.

The agitator or dasher 3, operates with a reversely rotary movement about a vertical axis and swings through an arc of substantially one hundred and eighty degrees during its operation. A perforated extractor basket 6, is mounted for rotation in the extractor tub 2, and itis also driven by the motor 4, through suitable mechanism which is housed and supported beneath the extractor tub.

The extractor tub 2, and the washer tub I, are secured in place between a stamped metal base member 1, and a die-cast apertured metal directly. to the base member. The supporting legs are provided with casters III, to facilitate moving the machine about from place to place.

The extractor tub and the washer tub are supported on the base member I and are secured thereon in any suitable manner such as by clamping them between the top plate and the base member as is described in detail in our copending application above referred to.

A water supply hose IL connects the machine with hot and cold water service supply lines (not shown). combined water treatment material dispenser, valve, strainer and spray nozzle structure. The valve and spray nozzle are arranged so that the water supplied by way of the hose II, may be controlled and directed into either the washing container I, or into the extractor basket 6.

The machine is provided with a pump I2, which is connected to a drain hose I3, that terminates in a gooseneck I4. The gooseneck is connected to the hose by means of a swivel coupling I5. The gooseneck is provided for the purpose of holding the hose in position to discharge into the washer tub or elsewhere as desired. The bottom of the extractor tub 2 has a drain opening which is directly connected 'to the pump inlet by the conduit I6 and it is continually drained by the pump during the operation of the machine. The draining'of the washer tub I, .15 under QQZlfirol of top plate 8. Three supporting legs 9 are secured The top plate 8, pivotally supports a to a drain opening in the tub bottom and which communicates at its outlet side with the pump I2 by way of the conduit I8.

The operation of the agitator 3, is controlled by means of a suitable control lever, to which is secured ahand grip or handle I9. The handle I 3 is capable of occupying three different control positions. In the first position, the motor 4 is inoperative. In the second position, the motor is connected to an electric circuit and thus placed in operation. In the third position of the control lever, the washing machine agitator '3 is connected in operated relation with the gear mechanism in the case 5 and-with the driving motor;

The top plate 8, is provided with openings 20 and 2|, which register with the washer and extractor tubs, respectively. A removable cover may be provided for the tub opening 20 if desired. A cover 22, is pivotally supported-by the top plate 8 on a horizontal axis adjacent to the extractor opening 2|. The opening andclosing of the cover 22 stops and starts the rotation of the extractor basket 6. The control of the extractor basketis accomplished by means of av cam 23, which is integrally formed with the cover 22,. and

' by other mechanism which will be described in detail in the latter part of this specification.

The arrangement of the extractor control is suchthat whenthe extractor cover '22 is in its open position, as shown in Figure 1, the extractor basket 6 is disconnected from its driving mechanism and a brake is applied to prevent its The motor 4 is connectedin driving relation tothe operating elementslocated in the gear case "4 by any suitable power transmission means.

ing mechanism are housed in a gear case formed y from upper andlower mating halves 25 and 26 respectively. A worm shaft 21 extends from the gear case and is connected at its outer end.

to the horizontal drive shaft 24 by means of a universal joint 28. The universal joint is provided with a dust-excluding, grease-retaining cover 29. A spring 30 is carried in one end of the drive shaft 24 to take up end play and prevent the vibration of the shaft whenit operates. The inner end of the shaft 21 is journaled in a plain bearing 3| and atits opposite end it is received in-an anti-friction bearing 32 carried by the extractor gear case base 26. A helical gear 33 isrigidly fixed on'the shaft-21 at a point intermediate the ends thereof. An oil sealing memher 34 prevents the escape of oil from about the bearing 32. The helical gear 33 engages a second helical gear 35, mounted for rotation about a vertical axis. A third helical gear 36,

carried by the horizontal pump shaft 31 meshes.

with the helical gear 35 for the purpose-of driv-- ing the pump I12. A ball thrust bearing 38 is provided .to take the end thrust of the shaft 21. The oil sealing member 34 is formed from a leather washer having a flanged portion for contacting with the outer surface of the. coupling member 39. A garter spring 4|) maintains the flanged portion of the washer 34 in sealing contact with the coupling member 39. A sheet metal cup having a pressed fit in the seal receiving aperture of the gear case, serves to hold the was er 34 and its spring 40 in place.

A shallow helical groove 42 is formed on the surface of the coupling member 39 at the place where it is in contact with the washer 34.- During the rotation of the shaft 24 and the coupling member 39, the groove 42 wipes oil off the washer 34 and returns it to the gear case.

The coupling member 39 is threaded to the shaft 21 and serves to hold the inner race 53 of the bearing 32 on this shaft. The outer race 44 of this bearing is held in the gear case by the threaded cup 45. A pressed metal cup 46 is gripped by the outer race 44 of the anti-friction bearing while its inner race 43 holds a washer 41 in position on the shaft 25 at a point adjacent to the mouth of the cup 46. A washer 48 of fibrous packing material is carried in the cup 46. This washer cooperates with the cup 46 and the washer ll in preventing dirt and grit from being carried by the oil in the gear case to the bearing 32.

The portion of the shaft 21 which is received in the bearing 3| is provided with a helical groove 2% on its bearing surface. This groove serves to pump oil inwardly along the bearing 3| and then upwardly through the communicating cored passageways 59 and 59 and formed respectively in the lower and upper halves 26 and 25 of the gear case. The upper passageway 50 communicates with a vertical slot 5| formed in the extractor shaft bearing 52 by Way of a hole 53 drilled through the bearing 52. The slot 5| serves to feed oil to the top of the bearing from whence it is returned to the gear case by means of a second slot 54 formed in the opposite side of the bearing. By reason of the arrangement just described the bearing surface of the bearing 52 is supplied under pressure with an adequate amount of lubricant during the operation of the shaft 27.

An extractor basket supporting shaft 55 is journaled in the bearing 52 and at its lower end it has an anti-friction bearing 55. This bearing is fitted in a suitable opening provided in the bottom half of the extractor gear case. A closure cap 5'! secures the'bearing 55 in place in the gear case base 26. The extractor shaft 55 is provided with a threaded lower end for reception of a lock nut 58, by means of which the shaft is secured to the inner race of the antifriction bearing 56 and is thus held against axial movement.

A shaft seal is provided at the upper end of the extractor shaft bearing 52 to prevent the ingress of water into the extractor gear case and to prevent the escape of oil from such gear case to the extractor tub. This seal is formed with an annular ring 6|] of graphite bronze fitted over .the end of the bearing 52 in a leak-proof manner such as by soldering, and an annular member 6| having a smoothly finished face 62 forms sealing contact with the ring at this point. The annular member 6| is urged against the ring by means of a spring 63 abutting at its upper end against a washer 64 engaging a flexible packing member 65. The packing member 65 at its side opposite to the washer 64, engages the V-shaped edge 66 of a ring 61 which is secured to the shaft 55 by means of a set screw 63. The flexible packing member 65 is thus urged in sealing relation against the surface of the shaft 55 and against the annular member 6| and a single spring serves to maintain the packing member 65 and the face 62 in sealing contact with the associated parts of the device.

The modified form of seal shown in Figure '7 comprises a metallic bellows which is sealed and secured at its upper end to the extractor shaft 55. The lower end of the bellows is fitted with a sealing ring H, which frictionally engages the smoothly finished end 12 of the extractor shaft bearing 52. The bellows i9 is slightly compressed so that its natural resiliency will urge the ring 1| into sealing contact with the end 12 of the bearing 52 and thus provide a liquid tight seal at this point.

The lower half of the gear case or base 26, is formed with a bearing 13 for a control shaft 14. The cover or upper half 25 of the extractor gear case is formed with a central opening, for reception of the upper bearing 52 of the extractor shaft 55. The extractor shaft bearing 52 is exteriorly threaded at a point intermediate its height and it is also provided with an outwardly extending flange 15, at its lower end. A nut 16, engaging the threaded part of the bearing 52, is provided for. securing the extractor gear case to the frame of the machine and to the extractor tub. Suitable gaskets H are provided to prevent leakage of water about the central opening in the extractor tub through which the bearing 52 projects. The gaskets H are formed from a soft yielding material such as soft rubber to provide a flexible joint at this point.

The extractor shaft 55 is provided with a frusto-conical upper end 18, which is received in the frusto-conical socket 821 of. the extractor basket base 8|. The extractor basket 6 may be readily removed from the shaft 55 by reason of the form of coupling used which constitutes a detachable frictional driving connection between the basket and its driving shaft. A breather pipe 79, communicating with the interior of the extractor gear case is carried by the upper half 25 thereof.

The extractor basket base 8| is in the form of a bellshaped die casting. The side wall of the basket is formed by an inwardly tapering sheet metal conical drum 82 which is secured -to the base by the rivets S3. The taper of the shaft end 78 is such that the weight of the basket when loaded with work is suflicient to provide for a good frictional driving connection at this point, while at the same time, permitting a slight amount of slippage in starting and stopping the rotation of the basket.

Perforations 84 are formed in the side walls of the basket to permit the expelling of water from the basket during its operation. The base porticn of the extractor basket is provided with a plurality of holes 85, to permit the drainage of water from this portion of the basket. The upper end of the extractor basket carries an annular ring 86, which is provided to prevent clothes from dropping between the extractor basket and its tub 2. construction and is pressed or spun into position on the rim of the extractor basket.

The helical gear 35 is fixedly secured to a clutch member 81, which is freely journaled on the extractor shaft 55. At its upper end the clutch member 81 is provided with a conical clutch face 88. The member 8'! is held against 75 This ring may be of stamped-metal axial movement by the shaft shoulder 30 and the shaft collar III.

Cooperating with the clutch member 81, there is provided a second or driven clutch member 92, which has a lower conical clutch face 33, provided for cooperation with the clutch face 88 of the aforesaid member. The clutch member 32 is slotted at 95, for loosely receiving the shaft key 36. In this manner the member 32 is mounted for rotation with the shaft 55 and for axially slidable movement thereon.

A spring 91 is compressed between the top of the clutch member 32 and a washer 38, which is held in position on the shaft 55 by means of a pin' I00. The upper end of the vertically slidable clutch member 92 is formed with a frusto-conical brake face IOI, which engages a brake member I02 having a brake face I03 of similar contour.

The brake member I02 is provided with a pair of radially extending ledges I04, in which are provided for engagement by the fingers I05, of the clutch shifting fork I06. The brake member I02. has a pair of vertically channeled guideways I01 in which are received the guide members I08 which serve to prevent the rotation of the member I02.

The shifting fork I06 is fixedly secured to the rod 14, by means of a set screw I03. The rod 14 is j ournaled in a bearing 13, which is formed in the gear case base 26 and at its outer end it is provided with a crank arm IIO. An oil seal H is fitted in the outer end of the bearing 13, to prevent the escape of oil'from the gear case at this p int. The crank arm H0 is rigidly secured to th end of the rod 14 and held thereon by means of the nut III.v The crank arm H0 is engaged by the lower end of a rod II2, which is operated by means of the cam 23, provided by the extractor cover 22. Contact is maintained between the rod II2, the cam 23 and arm IIO, by means of the tension spring II3, which is secured at its ends to the crank H0 and to the washing machine base 1.

The lower end of the rod H2 is threaded for the reception of the bolt II4, by means of which its length can be readily adjusted. A lock nut H is provided for the bolt I I4. The head of the bolt is received in a shallow cup II 6, which is formed in the end of the crank arm I I 0. The washing machine top 8 has an apertured arm II1 integrally formed therewith for receiving and guiding theupper end of the rod H2. The lower end of this rod is guided in a bracket II8 which is carried by the machine base 1.

During the operation of the motor 4, with the parts in the position they occupy in Figure 1, the extractor basket will be at rest with the braking surfaces MI and I03 in contact with each other. To start the rotation of the basket 6, it is only necessaryto close the lid 22, whereupon the movement of the cam 23 allows the rod I I2 and the crank arm I I0 to rise under influence of the spring H3.

The movement of the crank arm H0 is transmitted to the shaft or rod 14, and its associated shifting fork I06, which is thereby moved downwardly, lowering the brake member I02 out of contact with the brake surface IOI. of the combined clutch and brake member 32. Coincidentally with this operation, the spring 31 moves the clutch member downwardly, bri ing the frictional clutch faces 88 and 93 into engagement, whereupon the basket 6 is driven by the rotating member 81.

The stopping of the extractor is accomplished by opening the lid '22. This operation moves the aforesaid extractor control elements in a reverse manner to that just explained, to separate the clutch surfaces 88 and 93 and to bring the braking surfaces IIlI and I03 into engagement whereby the basket is quickly brought to rest.

The pump I2 is of the impeller type and it comprises a pump case I 20 and a pump cover I2 I, which inclose a bladed impeller I22. The pump case I 20 has an extended portion in which is formed a bearing I23 and a packing chamber through which the pump shaft 31 extends. The pump case is secured to the extractor gear case base 26 by means of the screws I24.

The packing chamber of the pump case isarranged to receive in the order named, a spiral spring I25, a loosely fitted packing gland I26, the packing material I21 and a gland nut I 28. The packing gland I26 is loosely fitted in the packing chamber so that it is free to be moved by the spiral spring I25, to force the packing material I21 into sealing relation with the pump shaft 31. The extended portion of the pump case projects into the interior of the extractor gear case and the pump shaft and its bearing by reason of this arrangement, are lubricated by the oil carried in the extractor gear case.

The end of the pump shaft is threaded at I33, for receiving the bladed impeller I22 of the pump. The pump cover I2I is provided with a central inlet opening I3I, which communicates with two branched conduits I32 and I6. The branch I32 connects with the valve I1 and the branch I6 connects with a nipple I34 provided in the bottom of the extractor tub.

These connections are made by means of flexible hose couplings I8 and I33, respectively, which are suitably secured at their ends to the branches I 32 and I 6, and to the aforesaid parts. The fit ting connecting the pump with the extractor tub, comprises a nipple-I34 which is welded to the bottom of the tub 2. A screen member I35 is frictionally held in the nipple I34.

The bottom portion of the extractor tub, is formed at one side with an apertured trough-like depression I36, so that the nipple just mentioned, enters the tub tangentially and on an angle of about forty-five degrees with the horizontal. The side wall of the tub is bent inwardly at a point opposite to the drain opening as indicated by the numeral I31, so that the drain opening is located in a well defined pocket formed by the bottom and side walls of the tub 2. By this arrangement the rotation of the basket tends to force the liquid in the tub out through the stated drain opening provided for carrying away the water in the extractor tub. The natural movement of the water in the extractor tub is in a direction so that it tends to escape from the extractor tub by way of the stated drain opening.

The pump cover I2I carries a trap for solid materials. The trap is fitted with a removable screen I31, which is held in position by means of the removable closure cap I38. The screen is located in the cover between the pump inlet and the conduits communicating with the tub drain openings and it serves to prevent small articles of clothing and other materials from getting into the pump case.

The draining of water from the washer compartment is under control of the valve I1. This valve is of the plug type and its plug is connected for rotational movement to a control handle I40. For the position of the handle as shown in Figure 1, the valve is in its open position and when the handle is turned about ninety degrees in a counter-clockwise direction, the valve is closed. The pump case is of snail-shape construction and has a tangential outlet Mi, on its periphery for connection with the drain hose I3.

The top plate 8 is formed with an opening I42, for receiving the gooseneck I4, of the drain hose I3. As best shown in Figure 9, this hole tenninates in a curved lip I43, which acts as a sort of a guard or trap to prevent the escape of water from the tub when the agitator 3 is working and when the gooseneck is not in its hole I42.

The lower half 26, of the extractor gear case is provided with three 'apertured ears, upon the upper surface of which are carried rubber pads or washers I44. The pads are apertured for re ceiving the bolts I45 which engage with nuts riveted to the base 1 by means of which the gear case is secured to the base 6. Rubber washers I46 are also provided between the bolt heads and the gear case so that'the case is secured to the base 1 in a resilient and yielding manner. This arrangement cooperates with the flexible attachment of the extractor bearing 52 to the casing 2 to permit the extractor and its driving mechanism to have a. limited amount of movement with respect to the rest of the machine which allows the extractor to gyrate a slight amount and generally serves to reduce vibration and lessen the strains imposed on the machine during the operation of the extractor.

A water supply conduit II is connected by means of a coupling I46, to the terminal portion of an" L shaped fitting I41, which extends from the side of the machine. The fitting I41 is connected at its opposite or upper end to thetop plate 8 of the machine, by means of a look nut I48, which engages with the threaded end portion of the fitting, whereby to secure it in place on the top plate 1. The lock nut I48 also serves to hold a ported sleeve I50 in position in the fitting I41.

The sleeve I50 is of tapered construction and has a pair of spaced ports or openings I5! and I52 provided for communication with the fitting I41. A hollow tapered valve plug I53 is journaled in the member I50. The valve plug has a port I 54, which can be brought into registry with either of the ports I5I or I52 of the member I50, and thus provide for fluid fiow through the valve. The plug I53 is held in sealing relation with the member I50, by means of a nut I55 and washer I56, which are secured to the threaded end portion I51 of the plug and which engage the member I50. 7

An integrally formed nozzle I58 and operating handle I60 are fixedly secured to the plug member I53, by means of a threaded rod I6I and a container I62 which receives the rod in a threaded boss I63 formed in the bottom thereof. A glass cylinder I64 is thus clamped between the container I62 and the nozzle I58. A removable filter screen I65 is held in place by the'cylin-der I64 over the inlet opening of the nozzle I58, for the purpose of preventing solid particles of dirt and foreign material from passing through the nozzle I58 and staining the clothes. I65 cooperates with the'cylinder I64 to hold water soluble granular materials discharged from the compartments I62 and I62 of the container and which are provided to sterilize, blue or otherwise treat the clothes in the extractor basket orto treat the water supplied to the washer tub. These materials may be in the form of a water soluble bluing material, a water softener com- The screen pound, pulverized or granular soap or any other soluble material which it might be desirable to add to the water supplied to the difierent compartments of the machine.

The discharge of material from the compartments I62 and I62 is under control of a pair of valves I66 and I61. This arrangement permits the carrying of two different materials, one for the treatment of the wash water and the other for the treatment of the rinse water. The valves I66 and I61 have springs I66 and I61 to hold them in closed position. The valves are arranged to discharge a measured quantity of material when their exposed ends I66 and I 61 are depressed.

In using the water treating device the compartments of the container are first filled with suitable materials such as bluing for one compartment and soap for the other. When the nozzle is turned to discharge water into the Wash tub a measured quantity of soap can be discharged into the compartment surrounded by the glass cylinder I64 where it is there dissolved and carried into the washer tub by the water passing through such compartment. In a similar manner when the nozzle is turned to discharge into the extractor basket for rinsing purposes, a measured amount of bluing can be addded to the rinse water discharged by the nozzle I58.

In Figures 1 and 8, the spin-rinse valve parts are shown in the position they occupy when water is being discharged into the washer tub. When the handle is rotated so as to bring the end of the nozzle over the extractor container '6, the valve plug port I54 registers with the relatively small port I5I of the sleeve I50, and a limited flow of water is discharged into the extractor tub for the purpose of rinsing and sterilizing the clothes contained therein, during the rotation of the extractor basket. The nozzle I58 and the cover 22 are arranged so that the nozzle can be swung under the cover when in its closed position.

The amount of water discharged into the extractor during the spin rinse operation is limited by the size of the valve port I5I, so as to be slightly less than the maximum flow that the pump I2 is able to handle. In directing the nozzle I58 to discharge into the difierent compartments of the machine, the port I54 is brought into registry with either the small port I5I or the large port I52, in accordance with the position of the nozzle. When the end of the nozzle overlies the portion of the top plate 8, which separates its openings 20 and 2|, the valve ports are in a -closed position and no water flows through the nozzle.

The spray nozzle is provided with a small opening I68 intermediate its length which serves to discharge a small stream of water between the side walls of the extractor container and the extractor casing when the nozzle is in position to discharge into the extractor. The purpose of supplying water at this point is to wash away accumulations of soap suds which might gather between the adjacent parts of the extractor conpossible to perform all of the customary washing and rinsing operations on the clothes without removing the clothes from the machine. In addition to these advantages, the spin-rinse device permits the use of scalding hot water and disinfectants to sterilize the clothes.
