Referring now to FIG. 1 of the drawings, the clothes washing machine there illustrated is of the spin-tub type and of the general construction and arrangement of that disclosed in US. Patent No. 2,639,618, granted on May 26, 1953 to Jacob W. McNairy. More particularly, the machine 10 comprises a substantially square supporting base 11 carrying wall structure defining an upstanding casing 12 including a substantially horizontally disposed top wall 13 having a top opening therein provided with a cooperating top door 14 arranged for movements between open and closed positions with respect thereto. Housed within the casing 12 is an upstanding drain tub 15 that is suitably supported upon the base 11 and provided with an open top that is sealed against the underside of the top wall 13 in surrounding relation with respect to the top opening therein. A unitary mechanism 16 is arranged in upstanding position in the lower portion of the casing 12 and suitably supported upon the base 11 by structure indicated at 17. The mechanism 16 includes a casing 18 that is arranged in an opening provided in the bottom wall of the drain tub 15 and sealed in place, whereby the lower portion of the casing 18 is disposed below the bottom wall of the drain tub 15 and the upper portion of the casing 18 is disposed above the bottom wall of the drain tub 15. The casing 18 houses in the lower portion thereof an electric drive motor 40 of the two-speed reversible-rotor type that is also of the 4- pole, 6-pole, split-phase, induction type, as described more fully hereinafter; the rotor of which drive motor 40 is operatively connected to a water pump, not shown, that is also housed within the casing 18. In the arrangement the pump mentioned is provided with an inlet to which there is connected an inlet conduit 15a communicating with the bottom of the drain tub 15, and also an outlet to which there is connected an outlet conduit 15b extending to drain plumbing, not shown. In the arrangement, rotation of the rotor of the drive motor 40 in at least the reverse direction thereof operates the pump mentioned, so that any water in the drain tub 15 is pumped therefrom to the drain plumbing via the conduits 15a and 15b in an obvious manner.
Also, the unitary mechanism 16 comprises an outer rotatable element 19 arranged adjacent to the upper end of the casing 18 and disposed exteriorly thereof and positioned in the lower portion of the drain tub 15; which rotatable element 19 carries an upstanding spin tub 20 that is of conventional construction provided with a substantially annular wall that is upwardly and outwardly flared and having an open top disposed somewhat below the top opening provided in the top wall 13 and in alignment therewith, thereby to accommodate ready placement and removal of the clothes with respect to the spin tub 20 through the top opening mentioned, when the top door 14 occupies its open position. Further, the mechanism 16 comprises an inner Oscillatable element 21 projecting through the extreme upper end of the rotatable element 19 and carrying an upstanding agitator 22 arranged substantially centrally within the spin tub 20. Moreover, the upper open end of the spin tub 20 carries the usual balance ring 23 through which an annular array of openings 23a are arranged for the centrifugal discharge of the water therethrough from the spin tub 20 into the drain tub 15.
Finally, the unitary mechanism 16 comprises operative mechanism for selectively interconnecting the rotor of the drive motor respectively to the agitator 22 and to the spin tub 20. In the arrangement, when the rotor of the drive motor 40 is rotated in the forward direction, the agitator 22 is oscillated thereby, and when the rotor of the drive motor 40 is rotated in the reverse direction, the spin tub 20 is rotated thereby. Of course, oscillation of the agitator 22 effects a washing action upon the clothes suspended in the wash water contained in the spin tub 20, while rotation of the spin tub 20 effects a waterextraction action upon the clothes contained in the spin tub 20. Specifically, rotation of the spin tub 20 causes the wash water contained therein to be flung therefrom by centrifugal force and then causes water absorbed by the clothes to be extracted therefrom by centrifugal action and flung from the spin tub 20. The water flung from the spin tub 20 is caught by the drain tub 15, whereby it is pumped to the drain plumbing, not shown, by the operating pump previously mentioned that is housed within the casing 18 of the mechanism 16. Thus, the washing and water-extracting actions may be selectively effected upon the clothes contained in the spin tub 20 by selectively controlling the drive motor 40 in order to cause rotation of the rotor thereof in the respective forward and reverse directions, as required.
Further, the machine 10 comprises a water supply system indicated schematically as including a hot water supply pipe 24 and a cold water supply pipe 25, as well as a delivery tube 26 directly communicating with the open top of the spin tub 20. Also, a valve 27 is arranged in the hot water supply pipe 24 and a valve 28 is arranged in the cold water supply pipe 25. The valves 27 and 28 are of the solenoid-0perated type, the solenoids thereof being respectively indicated at 27a and 28a; and the valves 27 and 28 are biased into their closed positions. When the solenoid 27a is energized, the valve 27 is operated into its open position so that hot water is supplied from the hot water supply pipe 24 via the tube 26 into the spin tub 20; and when the solenoid 28a is energized, the valve 28 is operated into its open position so that cold water is supplied from the cold water supply pipe 25 via the tube 26 into the spin tub 20. Of course, the conjoint operations of the valves 27 and 28 into their open positions bring about the supply of warm water via the tube 26 into the spin tub 20, as a consequence of the mixing of the hot water from the hot water supply pipe 24 and the cold water from the cold water supply pipe 25.
Further, the machine 10 comprises a detergent dispenser 30 and a bleach dispenser 35. The detergent dispenser 30 is of the solenoid-operated type, the solenoid of which is indicated at 30a, and is provided with a delivery tube 31 directly communicating with the open top of the spin tub 20. Likewise, the bleach dispenser 35 is of the solenoid-operated type, the solenoid of which is indicated at 35a, and is provided with a delivery tube 36 directly communicating with the open top of the spin tub 20. The dispenser 30 is adapted to contain a suitable liquid detergent and is operative in response to energization-deenergization of the solenoid 30a to effect the delivery of a measured volume or charge of the liquid detergent therefrom via the tube 31 into the spin tub 20. Likewise, the dispenser 35 is adapted to contain a suitable liquid bleach and is operative in response to energizationdeenergization of the solenoid 35a to effect the delivery of a measured volume or charge of the liquid bleach therefrom via the tube 36 into the spin tub 20.
In the machine 10, the valves 27 and 28, as well as the dispensers and 35, are suitably housed in the casing 12; and preferably, the dispensers 30 and are provided with respective fill conduits, not shown, that are accessible through the top opening provided in the top wall 13, when the top door 14 occupies its open position, so as to accommodate the ready filling thereof with the required liquids mentioned. Of course, it will be understood that in FIG. 1, the showings of the water supply system and the dispensers 30 and 35 are entirely diagrammatic and that actually these elements of the machine 10 are housed within the casing 12, as previously noted.
Referring to FIG. 5, it will be observed that the drive motor of the 4-pole, 6-pole, split-phase, induction type includes a reversible rotor 41 and a cooperating frame carrying a 4-pole run winding 42, a 6-pole run winding 43 and a 4-pole start winding 44. The rotor 41 is carried by an operating shaft 45 to which there is connected a speed-responsive device 46 of the fly-ball governor type that includes a movable shaft 47 carrying two contact bridging members 48 and 49. Each of the contact bridging members 48 and 49 is provided with both front and rear contact sets governed thereby.
When the 4-pole run winding 42 is energized with forward polarity, the rotor 44 runs in the forward direction at its high speed of approximately 1725 rpm. effecting normal oscillation of the agitator 22 at a rate of about 64 cycles per minute that is suitable for washing normal fabrics; and when the 6-pole run winding 43 is energized with forward polarity, the rotor 44 runs in the forward direction at its low speed of approximately 1140 rpm. effecting gentle oscillation of the agitator 22 at a rate of about 45 cycles per minute that is suitable for washing delicate fabrics. When the 4-pole run winding 42 is energized with reverse polarity, the rotor 44 runs in the reverse direction at its high speed of approximately 1725 rpm. effecting normal spinning of the spin tub 20 at a speed of about 640 r.p.m. that is suitable for waterextracting normal fabrics; and when the 6-pole run winding 43 is energized with reverse polarity, the rotor 44 runs in the reverse direction at its low speed of approximately 1140 rpm. effecting gentle spinning of the spin tub 20 at a speed of about 420 rpm. that is suitable for water-extracting delicate fabrics.
Referring now to FIGS. 1, 7 and 8, the rear portion of the top wall 13 carries an upstanding backsplash 29 that, in turn, carries a control console embodying the features of the present invention.

As best shown in FIG. 5, the program controller 50 further comprises a plurality of insulating cams 7B, 6B, 1B, 3B, B, 2B, 6T, 4T, 1T, 4B, 5T, ST and 2T, that are rigidly secured to the operating shaft 51, and that respectively control the armature springs C1, MC, C2, FL, F2, MP, S2, S4, P5, P2, P3, P4 and P6. The armature springs C1, MC, FL, F2, MP, S2, S4, P2, P3 P4 and P6 respectively govern the pairs of switch springs CW, HR and H, PR and PF, ML and BD, NF and W, S and K1, J1 and K2, J2 and A1, A2 and A3, B1 and A4, B2 and BP, E; while the armature springs C2 and P5 respectively govern the single switch springs CR and SS.
Also, the operating shaft 51 is mounted for longitudinal axial movement, as well as for the rotary movement previously described; whereby the operating shaft 51 carries a contact bridging member 60 that is adapted selectively to bridge an associated pair of front contacts and constituting a line switch. More particularly, when the manual dial 52 is depressed, moved inwardly toward the front wall 101, the operating shaft 51 is moved longitudinally inwardly so as to actuate the line switch 60 into its open position; conversely, when the manual dial 52 is withdrawn, pulled outwardly away from the front wall 101, the operating shaft 51 is moved longitudinally outwardly so as to actuate the line switch 60 into its closed position.
Also, the program controller 50 comprises a shaft 54 that is mounted only for rotary movement; and the outer end of the shaft 54 is connected to the adjacent inner end of the operating shaft 51 by an associated sleeve-like connector 55 that accommodates the relative longitudinal axial sliding movements of the operating shaft 51 with respect to the shaft 54, while maintaining the normal rotary connection therebetween. Further, the program controller 50 comprises a timer motor TM and a position advance motor PA, both of the synchronous type and preferably Telechron motors. The timer motor TM comprises an operating shaft 56 that is connected by a gear box 57 and an overrunning clutch 58 to the inner end of the shaft 54; and the position advance motor PA comprises an operating shaft 56' that is connected by a gear box 57' and an overrunning clutch 58' to the inner end of a shaft 54' that is mounted for rotation adjacent to the shaft 54. Also, the intermediate portions of the shafts 54 and 54' respectively carry gears 59 and 59' that are meshed. In the arrangement, energization of the timer motor TM effects rotation of the operating shaft 51 at a relatively slow speed in the clockwise direction and on a timed basis; whereas energization of the position advance motor PA effects rotation of the operating shaft 51 at a relatively fast speed in the clockwise direction and without reference to time. The overrunning clutches 58 and 58' prevent interference between the motors TM and PA. and also accommodate manual rotation of the operating shaft 51 in the clockwise direction under the direct control of the manual dial 52.
Further, the program controller 50 comprises longitudinal or axial reset mechanism, as shown in FIG. 5, and that essentially comprises a ring 61 rigidly afiixed to the operating shaft 51 and carrying an outwardly or radially projecting pin 62. In turn, the pin 62 cooperates with a reset spring 63 that is externally supported, as indicated at 64. In the arrangement, when the operating shaft 51 occupies its rotary start or off position illustrated in FIG. 5, the manual dial 52 may be manually moved by the operator outwardly with respect to the front wall 101; whereby the operating shaft 51 is moved from its axial stop position into its axial start position. When the operating shaft 51 is thus moved into its axial start position, the line switch 60 is closed and the pin 62 carried by the ring 61 is moved axially outwardly with respect to the extreme outer end of the reset spring 63 (the pin 62 is moved above the extreme outer end of the reset spring 63, as illustrated in FIG. 5). As explained more fully hereinafter, at this time, the motors TM and PA effect rotation of the operating shaft 51 in the clockwise direction and out of its normal rotary start position. After approximately 330 of such rotation of the operating shaft 51 in the clockwise direction, the pin 62 is rotated below the extreme outer end of the reset spring 63 so that continued rotation of the operating shaft 51 in the next 30 and back into its rotary start position causes cooperation between the pin 62 and the extreme outer end of the reset spring 63 so that the operating shaft 51 is moved inwardly with respect to the front wall of the backsplash 29 (downwardly with reference to the reset spring 63, as viewed in FIG. 5) and back into its axial stop position. When the operating shaft 51 is thus moved back into its axial stop position the line switch 60 is opened in order to terminate operation of the motors TM and PA, whereby further rotation of the operating shaft 51 is arrested when it occupies its rotary start position, as well as its axial stop position.
Referring now to FIG. 2, the stationary ring-like index plate 53, with which the manual dial and index pointer 52 cooperates, carries the circumferentially arranged indicia: Off, First Wash, Spin, Second Wash, Spin, Bonus Rinse, Spin, Final Rinse, and Final Spin. As the cycle of the machine proceeds, the operating shaft 51 of the program controller 50 is rotated out of its rotary start position, causing the index pointer 52 to be rotated out of its corresponding Off position, these rotations being in the clockwise direction, as viewed in FIG. 2; whereby the progress of the cycle is indicated by the cooperation of the index pointer 52 with the index plate 53 in an obvious manner.
Considering now the general mode of operation of the program controller 50, rotation of the drive shaft from the gear box 57, in the clockwise direction, causes the friction clutch 58 to rotate the shaft 54 and the gear 59 in the clockwise direction, with the result that the gear 59 rotates the gear 59 and the shaft 54 in the counter clockwise direction. The friction clutch 58 permits such rotation of the shaft 54 with respect to the drive shaft extending from the gear box 57'; thereby to prevent interference by the motor PA with operation of the motor TM to rotate the shaft 54 in the clockwise direction at l r.p.h.
Rotation of the drive shaft extending from the gear box 57', in the counter clockwise direction, causes the friction clutch 58' to rot-ate the shaft 54 and the gear 59' in the counter clockwise direction, with the result that the gear 59 rotates the gear 59 and the shaft 54 in the clockwise direction. The friction clutch 58 permits such rotation of the shaft 54 with respect to the drive shaft extending from the gear box 57; thereby to prevent interference by the motor TM with operation of the motor PA to rotate the shaft 54 in the clockwise direction at l r.p.m.
When the motor TM is operated, while the motor PA is stopped, the clutch 58 effects the drive to the shaft 54, and the clutch 58 accommodates overdrive of the slowrunning shaft 54' with respect to the stalled shaft extending to the gear box 57'; whereby the operating shaft 51 is rotated in the clockwise direction at l r.p.h. On the other hand, when the motor PA is operated, simultaneously with operation of the motor TM, the clutch 58' effects the drive to the shaft 54, and thence via the gears 59, 59 to the shaft 54, and the clutch 58 accommodates overdrive of the fast-running shaft 54 with respect to the slow-running extending to the gear box 57; whereby the operating shaft 51 is rotated in the clockwise direction at l r.p.m.
The ratio between the gears 59, 59' may be lzl, since the speeds of the two shafts respectively extending from the gear boxes 57 and 57' may be established by the two gear trains respectively arranged in the two boxes 57 and 57'.
Considering now in greater detail the control circuit, as illustrated in FIGS. 3, 4 and 5, the same comprises a terminal block 2110 to which a source of electric power supply of 1l8-volts, single-phase, 60 cycle, A.-C., is connected; this source including two line conductors L1 and L2. Also, the machine 10 comprises a thermal protective device 2111 and a balance switch 2112. The thermal protective device 2131' may be of any suitable type, such, for example, as a resettable circuit breaker operative into an open position in response to an overload current condition for a given short time interval. The balance switch 2132' may be of any conventional type and is operative from a normal closed position into an open position in response to abormal vibration of the machine 10, such as may occur in a spinning operation of the spin tub with a heavy unbalanced load of clothes therein. In the circuit, the line conductor L2 is connected via the thermal protective device 231' and the balance switch 2112' in series relation to a supply conductor 2%.
Considering now in greater detail the wiring diagram, the switch springs of the program controller 50 terminate the conductors as follows:

In the switch 190: the contact segments 194, 195 and 196 are respectively connected to the conductors 224, 219 and 220.
The hot solenoid 27a is bridged across the conductors 212 and 204; the cold solenoid 28a is bridged across the conductors 212 and 2152; the bleach solenoid 35a is bridged across the conductors 212 and 2119; and the detergent solenoid 30a is bridged across the conductors 228 and 2114.
In the drive motor 41 the 4-pole start winding 44 is bridged across the conductors 214 and 216; the 4-pole run winding 42 is bridged across the conductors 208 and 225; and the 6-pole run winding 43 is bridged across the conductors 2G8 and 229. Also, the back contacts governed by the contact bridging member 4% respectively terminate the conductors 206 and 205; the front contacts governed by the contact bridging member 48 respectively terminate the conductors 206 and 208; the back contacts governed by the contact bridging member 49 respectively terminate the conductors 227, 225 and 215; and the front contacts governed by the contact bridging member 49 respectively terminate the conductors 227 and 229.
In the program controller 50; the timer motor TM is bridged across the conductors 2% and 22s; the position advance motor PA is bridged across the conductors 206 and 224; and the contacts governed by the contact bridging member 61) of the line switch respectively terminate the conductors 226 and L1.
Before proceeding with the particular controls that are carried out by the program controller 5t) in conjunction with the various switches 110, etc, in the automatic cycle of operation of the control circuit, reference is first made to FIG. 6, wherein there are disclosed the fundamental items of the program controller Sit, including the control cams 713, etc., the switch spring sets CWC1HR, etc., respectively governed by the control cams 78, etc., as Well as the sequence of the opening and the closing of the contact sets in the cycle of operation of the program controller 50. This chart is read from left to right; and the closure time intervals of each pair of switch springs are indicated by solid or filled-in blocks. For example: the control cam 7B actuates the switch spring C1 to close the switch spring CW and to open the switch spring HR during the first eight steps or time intervals of the cycle; the control cam 713 then actuates the switch spring C1 to open both of the switch springs CW and HR during the next twenty-two steps of the cycle; the control cam 7B then actuates the switch C1 to open the switch CW and to close the switch spring HR during the next twenty-two steps of the cycle; etc. Of course, the other control cams 63, etc, govern the other switch spring sets HMC-PR, etc, in a similar manner and simultaneously in the cycle of the program controller 50, as is evident from an examination of this chart.
Now assuming that an automatic program is to be carried out in the machine 10, when the manual dial 52 occupies its rotary start or off position and that the operating shaft 51 is in its axial stop position, the cir cuits are in the condition illustrated in FIG. 5 and indicated in FIG. 6. Further, assuming that in the program: two washes are desired, so that the tab 112 in the switch is depressed; hot first wash is desired, so that the tab 121 in the switch 121) is depressed; no soak is desired between the two sections of the first wash, so that the tab 132 in the switch is depressed; normal agitation in the washes is desired, so that the tab 141 in the switch is depressed; two rinses are desired, so that the tab 152 in the switch 154 is depressed; Warm rinses are desired, so that the tab 161 in the switch is depressed; normal spinning in the water-extractions are desired, so that the tab 171 is depressed; a normal load is indicated, so that the control dial 182 of the switch is rotated to its normal load position; and that a wash time interval of 10 minutes is indicated, so that the control dial 192 of the switch 191) is rotated to its IO-minutes position. At this time the circuits are in the preselected condition illustrated in FIGS. 3, 4 and 5; and hereinafter, this particular program thus preselected is referred to as the basic program" as a standard of comparison.
Also, it may be assumed that the detergent dispenser contains a suitable liquid detergent and the bleach dispenser contains a suitable liquid bleaching agent. Further, it may be assumed that each of these liquid dispensers is responsive to energization and subsequent deenergization of the solenoid thereof to effect operation thereof to dispense into the spin tub 20 a measured charge of the corresponding contained liquid.
The operator then places the clothes and the required initial detergent in the spin tub 20, and closes the top door 14. In order to initiate this preselected basic program, the operator merely manually pulls the control dial 52 of the program controller 50 outwardly with respect to the front wall 101, whereby the operating shaft 51 is moved from its axial stop position into its axial start position, so as to close the line switch 60.
In the present example, closure of the line switch 60 completes a circuit for operating the timer motor TM via the elements L1, 60, 226, TM, 206, 202, 201, L2; whereby the timer motor TM drives or rotates the operating shaft 51 of the program controller 50 in the clockwise direction, as viewed in FIG. 2, out of its rotary start or off position (also, #1 position as illustrated in the chart of FIG. 6), the drive connection including the elements TM, 56, 57, 58, 54, 55 and 51. Also, it is noted that at this time, since the operating shaft 51 occupies its axial start position, the pin 62 is disposed outwardly of the reset spring 63 (above the reset spring 63); which arrangement is subsequently involved in resetting the operating shaft 51 back into its axial stop position, as explained hereinafter. Also, closure of the line switch 60 completes a circuit for energizing the hot solenoid 27a, this circuit including the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, 27a, 204, H, MC, 205, 48, 206, 202, 201, L2. Energization of the hot solenoid 27a effects opening of the hot water valve 27, whereby hot water is introduced from the hot water pipe 24 via the tube 26 into the spin tub 20.
After a time interval of 4 minutes, the operating shaft 51 of the program controller 50 is rotated into position #5 (see the chart of FIG. 6; whereby the control cam 5B actuates the switch spring F2 to close the switch spring NF, thereby to complete forward start and run circuits for respectively energizing the start and run windings 44 and 42 of the drive motor 40. The forward start circuit mentioned includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, W, 211, 143, 225, 49, 215, I1, S2, 214, 44, 216, S4, K2, 208, 184, 163, 185, 210, NE, F2, 206, 202, 201, L2; and the forward run circuit mentioned includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, W, 211, 143, 225, 42, 208, 184, 183, 185, 210, NF, F2, 206, 202, 201, L2. The drive motor starts rotating its rotor 41 in the forward direction; whereby the centrifugal device 46 actuates the bridging members 48 and 49, when the rotor 41 gains about 60% of its normal running speed. Specifically, the device 46 actuates the bridging members 48 and 49 to open their back contacts and to close their front contacts. Opening of its back contacts by the bridging member 49, interrupts the forward start circuit for the start winding 44. Opening of the back contacts by the bridging member 48, interrupts the previously traced circuit for the hot solenoid 27a; whereby the hot water valve 27 returns to its closed position to cut-off the supply of hot water to the spin tub 20.
Closure of the front contacts by the bridging member 48, completes a forward holding circuit for energizing the run winding 42 of the drive motor 40; this forward holding circuit includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, W, 211, 143, 225, 42, 208, 48, 206, 202, 201, L2. Closure of the forward holding circuit effects continued energization of the run winding 42, so that the rotor 41 accelerates on into its normal running speed of about 1725 rpm. in the forwad direction, in order to effect oscillation of the agitator 22 at its normal rate of about 64 cycles per minute to produce a normal washing action upon the clothes suspended in the hot water in the spin tube 20. It is noted that operation of the drive motor 40 was thus initiated in position #5 of the operating shaft 51; whereby the hot water valve 27 was closed, as described above, with the result that the hot water was supplied into the spin tube 19a during a corresponding time interval of 4 minutes, producing a normal fill of hot water therein for use in the wash cycle.
When the operating shaft 51 is rotated into position #10, the control cam 5B actuates the switch spring F2 to close the switch spring BD; and when the operating shaft 51 is rotated into position #12, the control cam 5B actuates the switch spring F2 to open the switch spring BD; whereby a circuit is completed and then interrupted for energizing the solenoid 35a of the bleach dispenser, so as to cycle the same in order to cause a measured charge of the liquid bleach agent to be introduced via the tube 36 into the spin tub 20. The above-mentioned circuit for energizing the bleach solenoid 35a, when completed, includes the elements L1, 60, 226, P3, B1, 223, 154, 218, 133, 217, P6, E, 212, 350, 209, BD, F2, 206, 202, 201, L2.
When the operating shaft 51 is rotated into position #13, the control cam 18 actuates the switch spring C2 to close the switch spring CR, so as to complete a circuit for energizing the cold solenoid 28a; this circuit including the elements L1, 60, 226, P3, B1, 223, 154, 218, 133, 217, P6, E, 212, 28a, 202, C2, CR, 205, MC, PR, 206, 202, 201, L2. When the operating shaft 51 is rotated into position #14, the control cam 1B actuates the switch spring C2 to open the switch spring CR, so as to interrupt the circuit for the cold solenoid 28a. Thus, the cold water valve 28 is maintained open for a time interval of 1 minute, while the operating shaft occupies position #13, so as to cause cold water to be introduced via the tube 26 into the spin tub 20 during the first washing action in order to insure ample water in the spin tub 20 following the introduction of the liquid bleach thereinto from the bleach dispenser in position #12 of the operating shaft 51.
The washing action thus initiated in position #5 of the operating shaft 51 continues for a time interval of 10 minutes, whereupon the operating shaft 51 is rotated into position #15, with the result that the control cam 2B actuates the switch spring MP to open the switch spring W. Opening of the switch springs MP, W interrupts the forward holding circuit for energizing the run winding 42 of the drive motor 40, so that the rotor 41 stops to terminate the washing action of the agitator 22 in the spin tub 20. Stopping of the rotor 41 causes the device 46 to reset the bridging members 48 and 49 into their back positions, as shown in FIG. 5.
After a time interval of 1 minute, the operating shaft 51 is rotated into position #16, whereupon the control cam 2B actuates the switch spring MP to close the switch spring S, thereby to complete reverse start and run circuits for respectively energizing the start and run windings 44 and 42 of the drive motor 40. The reverse start circuit mentioned includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, S, 213, 173, 225, 49, 215, J2, S4, 216, 44, 214, S2, K1, 208, ML, FL, 206, 202, 201, L2; and the reverse run circuit mentioned includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, S, 213, 173, 225, 42, 208, ML, FL, 206, 202, 201, L2. The drive motor 40 starts rotating its rotor 41 in the reverse direction; whereby the centrifugal device 46 actuates the bridging members 48 and 49 at about 60% normal running speed.
Specifically, the bridging member 49 interrupts the reverse start circuit; and the bridging member 48 completes a reverse holding circuit for energizing the run winding 42 of the drive motor 40; which reverse holding circuit includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, S, 213, 173, 225, 42, 243, 48, 206, 202, 201, L2. The rotor 41 then accelerates into its normal running speed of about 1725 rpm. in the reverse direction; thereby to effect spinning of the spin tub 20 at its normal speed of about 640 r.p.m. to produce a normal water-extraction action upon the clothes therein. The wash water spun from the spin tub 20 is caught in the drain tub and pumped to the drain plumbing, not shown, in the usual manner.
Also, in position #16 of the operating shaft 51, the control cam 1B actuates the switch spring C2 to close the switch spring CR, thereby to complete a circuit for energizing the cold solenoid 28a, so as to effect opening of the cold water valve 28; with the result that cold water is introduced from the cold water pipe 25 via the tube 26 into the spin tube during spinning thereof. This effects a spraying action upon the clothes as they are spun in the spin tub 2t); and the water thus introduced into the spin tub 20 is expelled therefrom and caught in the drain tub 15 and then pumped to the drain plumbing, as previously explained. The circuit noted above for energizing the cold solenoid 28a includes the elements L1, 60, 226, P3, B1, 223, 154, 218, P5, SS, 217, P6, E, 212, 28a, 202, C2, CR, 205, NC, PR, 206, 202, 2111, L2.
Subsequently, after a time interval of 1 minute, the operating shaft 51 is rotated into position #17, whereby the control cam 1B actuates the switch spring CR to open the switch spring C2, thereby to interrupt the circuit for energizing the cold solenoid 28a, so as to effect closing of the cold valve 28 in order to terminate the introduction of cold water from the cold water pipe via the tube 26 into the spinning spin tub 20, with the result that the spray action described above is terminated.
The spinning of the spin tub 2t) initiated in position #16 of the operating shaft 51 continues for a time interval of 3 minutes, whereupon the operating shaft 51 is rotated into position #19, with the result that the control cam 2B actuates the switch spring MP to open the switch spring S. Opening of the switch spring, MP, S interrupts the reverse holding circuit for energizing the run winding 42 of the drive motor 40, so that the rotor 41 stops to terminate the spinning of the spin tub 20. Stopping of the rotor 41 causes the device 46 to reset the bridging members 48 and 49 into their back positions, as shown in FIG. 5.
After a time interval of 1 minute, the operating shaft 51 is rotated into position #20, whereby the control cam 6B actuates the switch spring MC to close the switch spring H, thereby to complete a circuit for energizing the detergent solenoid 338a; this circuit including the elements L1, 60, 226, P3, A3, 222, 114, 228, 36a, 2114, H, MC, 265, 48, 296, 202, 201, L2.
Also, closure of the switch springs MC, H complete a circuit for energizing the hot solenoid 27a; this circuit including the elements L1, 60, 226, 115, 223, 154, 218, P5, SS, 217, P6, E, 212, 27a, 2114, H, MC, 205, 48, 206, 202, 201, L2. Energization of the hot solenoid 27a effects opening of the hot Water valve 27, whereby hot water is introduced from the hot water pipe 24 via the tube 26 into the spin tub 26.
At this point, it is noted that the above-traced circuit for energizing the hot solenoid 27a is independent of the positions of the control switch 120; and since the control cam 7B maintains open the switch springs C1, CW, there is no possibility of energization of the cold solenoid 28a at this time. Thus, the second wash cycle always proceeds employing hot water in the spin tub 20.
After a time interval of 4 minutes, the operating shaft 51 is rotated into position #24, whereby the control cam 53 actuates the switch spring F2 to close the switch spring NF, thereby to complete forward start and run circuits for respectively energizing the start and run windings 44 and 42 of the drive motor 40. The forward start circuit mentioned includes the elements L1, 62, 226, 115, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, W, 211, 143, 225, 49, 215, 11, S2, 216, 44, 216, S4, K2, 268, 184, 183, 185, 210, NF, F2, 206, 202, 201, L2; and the forward run circuit mentioned includes the elements L1, 64), 226, 115, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, 4V, 211, 143, 225, 42, 298, 184, 183, 185, 210, NF, F2, 206, 202, 201, L2. The drive motor 40 starts rotating its rotor 41 in the forward direction; whereby the device 46 actuates the bridging members 48 and 42 in the manner previously explained. Specifically, the bridging member 49 opens its back contacts to interrupt the start circuit for the start winding 44. The bridging member 48 opens its back contacts to interrupt the circuit for energizing the detergent solenoid 30a and the circuit for energizing the hot solenoid 27a. The detergent dispenser 30 completes its cycle to introduce a measured charge of detergent via the tube 31 into the spin tub 2t); and the hot water valve 27 returns to its closed position to cut-off the supply of hot water to the spin tub 20. Closure of its front contacts by the bridging member 48 completes a forward holding circuit for energizing the run winding 42 of the drive motor 40; this forward holding circuit including the elements L1, 60, 226, 115, 223, 154, 218, P5, SS, 217, P6, E, 212, MP, W, 211, 143, 225, 42, 268, 48, 206, 2112, 201, L2. Closure of the forward holding circuit effects continued energization of the run winding 42, so that the rotor 41 accelerates on into its normal running speed of about 1725 rpm. in the forward direction in order to effect oscillation of the agitator 22 at its normal rate of about 64 cycles per minute to produce a normal washing action upon the clothes suspended in the hot water in the spin tub 2 2 in the usual manner. It is noted that the hot water valve 27 was opened in position #21 of the operating shaft 51 and was closed in position #24 of the operating shaft 51, whereby hot water was introduced into the spin tub 29 during a time interval of 4 minutes, so as to produce a normal fill of hot water therein for use in the wash cycle.
The washing action thus initiated in position #24 of the operating shaft 51 continues for a time interval of 3 minutes, whereupon the operating shaft 51 is rotated into position #27, with the result that the control cam 2B actuates the switch spring MP to open the switch spring W to interrupt the forward holding circuit for the run winding 42 of the drive motor 40, so that the rotor 41 stops to terminate the washing action of the agitator 22 in the spin tub 20. Also, the device 46 resets the bridging members 48 and 49 into their back positions, as shown in FIG. 5.
After a time interval of 1 minute, the operating shaft 51 is rotated into position #28, whereupon the control cam 28 actuates the switch spring MP to close the switch spring S, thereby to complete reverse start and run circuits for respectively energizing the start and run windings 44 and 42 of the drive motor 40.

The rotor 41 then accelerates into the normal running speed of about 1725 r.p.m. in the reverse direction; thereby to effect spinning of the spin tub 20 at its normal speed of about 640 rpm. to produce a normal water-extraction action upon the clothes therein. The wash water spun from the spin tub 20 is caught in the drain tub 15 and pumped to the previously mentioned drain plumbing.
Also, in position #28 of the operating shaft 51, the control cam 1B actuates the switch spring C2 to close the switch spring CR, thereby to complete a circuit for energizing the cold solenoid 28a, so as to effect opening of the cold water valve 28, with the result that cold water is introduced from the cold water pipe 25 via the tube 26 into the spin tub 20 during spinning thereof. This effects a spraying action upon the clothes as they are spun in the spin tub 20; and the Water thus introduced into the spin tub 20 is expelled therefrom and caught in the drain tub 15 and then pumped to the drain plumbing.

Subsequently, after a time interval of 1 minute, the operating shaft 51 is rotated into position #29, whereby the control cam 13 actuates the switch spring CR to open the switch spring C2, thereby to interrupt the circuit for energizing to cold solenoid 28a, so as to effect closing of the cold valve 28 in order to terminate the introduc tion of cold water from the cold water pipe 25 via the tube 26 into the spinning spin tub 20, with the result that the spray action described above is terminated.
The spinning of the spin tub 20 initiated in position #28 of the operating shaft 51 continues for a time interval of 3 minutes, whereupon the operating shaft 51 is rotated into position #31, with the result that the control cam 23 actuates the switch spring MP to open the switch spring S to interrupt the reverse holding circuit for the run winding 42 of the drive motor 40, so that the rotor 41 stops to terminate the spinning of the spin tub 20.
