Driving clutch 95 comprises a notched cam disc 96 which loosely fits within a shell 97 which is secured to the eccentric 78 by a key 98. Rollers 99 fit within the recesses 95 between the disc 96 and the inner periphery of the shell 97. When the disc 96 is rotated in the direction of the arrow A in Fig. 5, the rollers 99 will be wedged between the curved surfaces 100 and the inner periphery of the shell 97, thus effecting. a driving connection between the disc 96 and the eccentric 78 in the direction of the arrow A in Fig. 5. It will be apparent that'when' the disc 96 is rotated inacounter clockwise direction, as vewed in Fig, 5, the rollers 99 will be cammed' toward the notches 101 out of driving engagement with the inner periphery of the shell 97, thus breaking the driving connection between thedisc 96 and the eccentric 78. Driving clutch 105 comprises a notched cam disc 106 with the notches cut in a direction'reverse to those of the disc 96. This disc 106 loosely fits within a shell 107 which is secured to the eccentric 79 by a key 108. Rollers 109 fit within the recesses 105 between the disc 106 and the inner periphery of the shell.107, and upon rotation of the disc 106 in the direction of the arrow in Fig. 4, the rollers 109 are wedged between the inner periphery of the shell 107 and the curved surfacesof the disc 106, thus forming a driving .connectionbetween the disc 105 and. the eccentric 79. UPOIlIOtfllZlOIl of the disc 106 in a clockwise direction, as viewed in Fig. 4, the rollers 109 will be cammed toward the notches 110 and out of driving engagement withthe-innerperiphery of the shell 107, thusbreaking the driving connection betweenthe disc, 106 and" the eccentric 79. Discs 96 and 106 are provided with reduced' portions 112 and 113 respectively which together form a bearing for a worm gear 115 which cooperates with worm 64 on shaft,61.; Discs 96 and 106 andworm gear 115 are secured together by pins 116.

Reoersiag an0l stopping switch.

The means forilreversing and stopping the motor 60 comprises a switch-120 having two on positions and an off position.

This switch comprises contact arms 121 and 121* adapted for engagement with

stationary contacts

122, 123, 124, 125,-and 126, 127, 128, 129, respectively for reversing the direction of flow of .currentmthrough the field respectively. One terminal of the winding 69 is connected with contacts 128 and 123 by Wires 135 and 136 respectively. The opposite terminal of Winding 69 is connected with

contacts

124 and 129 by

wires

137 and 138 respectively. Switch 120 is connected with lever 150 by a rod 139 and an arm 140 which are pivoted at 141, the rod 139 being pivoted to the lever 150 at 142.

The means operated by a demand for water forcontrolling the operation of the reversing and stopping switch 120 includes the pressure operated

switches

42 and 43. These switches are adapted for operation when the pressures in the tanks 40 and 41 reach a predetermined low value, for example, 25 pounds, and will remain closed until the pressures in the tanks 40 and 41 reach a predetermined high value, for example, 50 pounds Such switches are shown in detail in the copending application of Kettering and Buvinger, Serial No. 299,195,'filed May 23, 1919. Switch 43 includes movable contact 46 and stationary contact 47. Magnet windings 155 and 156 cooperate with armatures or plungers 157 and 158 respectively, which are connected by .rod 159 provided with a stud 160. Windings 155 and 156 are connected together at one end thereof by wire 161. The other end of winding 155 is connected with movable contact 162 by wire 163, while the other end of winding 156 is connected with movable contact 164 by wire 165. Contact 45 is connected with a stationary contact 168 by wire 169, and contact 47 is connected with a stationary contact 166 by wire 167. Lever 150 is pivoted at .151 and is provided with

insulated branches

152 and 153 which are adapted to actuate the contacts 162 and 164 respectively. Lever 150 is provided with a forked end 153 which engages the stud 160. A spring 154 which is securedto the stud 160 and pin 155, tends to maintain the lever 150 in horizontal or normalposition, as viewed in Fig. 6, with contacts 162,168 and 164, 166 closed and the switch 120 in its normal or ofi' position, as indicated by the dotted lines in Fig. 7. VVindings 155 and 156 are connected with the source of current by

wires

170 and 130. Contacts 44 and 46am connected with the source of current by

wires

171, 172, and 133. I

Operation of the systems.

pounds, the pressure switch 42 will be operat'ed, whereb the contacts 44 and will be closed, Current will then flew from the source or current, threugh wire 1333, wife 172, through contacts 44. 331C145; the 169, through contacts 168: and 162, wire 163, winding and back he the ourceiof curr nt through

wires

170 and 130. Current fiowingthrough the winding 155 will cause the plunger 157 to be attracted upwardly as viewed Fig. 6. This movement of the plunger 157 will move the lever 150 on its pivot 151, to the position shown in Fig. 6, th'us causing the branch 153to open the contactsltih'and 164 aiid disabling the winding 156; This rncvement" of lever 150 will cause switch 120 to be rotated from the full line position. shown 7 to the position shown in F 1g. 6. Current will then flow from the" source of current through wire 133, w'ire 134', Contact 127, switch blade 121, contact 129, wire 138, wire 137, through series winding 69 the direction of arrow X in Fig. 6, wire 135, wire 136, contact 123, switch blade121, contact. 125,'wire 132, wire 131, brush 70, across the armature of the mowi- 60, brush 71, wire 130, back to the source of current. The currentthus flowing through the winding69 will cause the motor to rotate in oiie direction. This rotation of the motor is transmitted through thewo'rin 64 and worm gear 115 to the discs 96 and 106 ofthe one-

waydrit ing clutches

95 and 105 respectively, causing rotat ion of the same in the direction of the arrow A in Figs. 1, 5, and 6. Therefore thismovement of the woini" gear 115 will ette'cta driving connection between the clutch 95 and the eccentric 78 in the direction of the arrow A in Fig. 6. Rotation of the eccentric 78 will cause eccentric strap 82 to transmit movement to the cross head 31 which is connected to the piston of pump 21 by connecting rod 29. Thus the pump 21 will be operated to furnish water to the tank 40. If the demand for water is less than the amount of water being delivered to the tank .40, the pressure will gradually be built up in the tank 40, but of course if the demand is equal to the amount delivered to the tank, the water will be directed to the service pipe 37 direct from the pump 21. After the demand for water ceases, the pump 21 will co'ntinue to operate until the pressure within the tank 40 has reached pounds. At thistime, the pressure switch 42 will operate to break the

contacts

44, 45. hen these contacts are broken the current through the winding 155 will likewise be broken and the plunger 157 will be deenergizedJ The spring 154 will then return the plunger 157, 158 and lever 150 to normal position, thus causing the contacts 164 and 166 to be closed. The re turn of lever 150m normalposition will also return the switch 120 to the normal position indicated by" dotted lines in Fig. 7, thus breakingthe niotor circuit and stopping the meter 60. I

When there is a demand for hard water, and the pressure within tank 41 has been reduced to 25' pounds, the switch 43 will operate to close

contacts

46 and 47. Current will then now from the source of current through wire 133, wire 172, wire 171, through

contacts

46 and 47, wire 167, across contacts 166 and 164, wire 165, through winding 156, wire 161, wire 170, and wire 130 back tothe source of current. Current flowing through winding 156 will energize the plunger 158, tending to draw it downwardly as viewed in Fig. 6. This downward movement of plunger 158 will move the lever 150 on its pivot 151, causing branch 152 to open

contacts

168 and 162, thus disabling the winding 155. This movement of the lever 150 will rotate the switch 120 to the full line position shown in Fig. 7, at which time current will flow from the source of current throughwire 133, through con tact 126, across Switchblade 121 contact 128, wire 135, through the series winding 69 in the direction of the arrow Y inFig. 6, wire 137,.cont'act 124, across switch blade 121, contact 122, wire 131, motor brush 70, across the armature of the motor 60, brush 71, Wire 130 back to the source of current. The current thus flowing through the wind ing 69 will cause the motor to rotate in a direction opposite to that described above. This rotation of the motor is transmitecl through'the worm 64 and the worm gear 115 to the discs 96 and 106 of the one-way driving clutches and 105 respectively, causing rotation of the same in the direction of the arrow B in Figs. 1, 4, and 6. Therefore this movement of the worm gear 115 will effect a driving connection between the clutch 105 and the eccentric 79 in the direction of the arrow B in Fig. 6. Rotation of the eccentric 78 will cause eccentric strap .83 to transmit movement to the cross head 32 which is connected to the piston of pump 22 by connecting rod 30. Thus the pump 22 will be operated to furnish water to the tank 41. If the demand for water is less than theamount of water being delivered to the tank 41, the pressure will gradually be built up in the tank 41, but of course if the demand is equal. to the amount delivered to the tank, the water will be directed to the service pipe 38 direct from the pump 22. After the demand for water ceases, the pump 22 will continue to operate'until the pressure within the tank 41 has reached 50 pounds. At this time, the ucssu're switch 42 will operate to break the

contacts

46 and 47. \fVhen these contacts are broken, the current through the winding 156 will likewise be broken andthe plunger 158 will be de-energi'zed. The spring 154 willthen return the plungers 158,

157 and lever 150 to normal position, thus causing the

contacts

162 and 168 to be closed. The return of lever 150 to normal position will also return the switch 120 to the normal position indicated by dotted lines in Fig. 7, thus breaking the motor circuit and stopping the motor 60.

It may happen that when there is a demand present in the hard water system and the pump 21 is operating, a demand may arise in the soft water system to cause operation of the pressure switch 42, whereby the

contacts

46 and 47 will be closed. Upon the occurrence of such a condition, the system which is in operation at the time the added demand arises, will continue to operate until the pressure within its respective tank has reached its high value or 50 pounds. Immediately upon the breaking of the pressure switch contacts in that system, the direction of rotation of the motor 60 will be reversed as heretofore described, and thus bring into operation the pump in the other system, to supply the demand that has been created in that system. The means for accomplishing this includes the

branches

152 and 153 of the lever 150. In the normal position of the lever 150, the

contacts

162, 168, and 164, 166 are closed. When the lever 150 is in either one of its operative positions, however, one set of these contacts is closed and the other set is open. In other words, when the winding 155 is effective to draw the plunger 157 upwardly, the contacts 164 and 166 are opened and

contacts

162 and 168 are closed, thus rendering ineffective the winding 156, and vice versa, when the winding 156 is effective to draw the plunger 158 downwardly, the

contacts

162 and 168 are open-ed and the contacts 164, 166 are closed, thus rendering ineffective the winding 155.

It may also happen, when both systems are at rest, that a demand will arise in both sys tems at the same time, causing closure of

contacts

44, 45 and 46, 47 at the same time. Under this condition, with the

contacts

162, 168 and 164, 166 closed, there apparently would be no operation of either system. However, in order to overcome such a difliculty, the windings 155 and 156 may be of relatively different strength, one having more turns than the other. Thus it will be seen that upon the occurrence of such a condition as above stated, the stronger winding would tend to bring into operation that system with which it was connected. In the present disclosure, the winding 155 has been shown with a greater number of turns than the winding 156. Therefore, inasmuch as the winding 155 is connected with the soft water system, the soft water system would be the preferred one. Magnet 156 is strong enough to hold the plunger 158 in attracted position against the pull of magnet 155 but is not strong enough to pull the plunger 157 away from magnet 155 in case both magnets should be energized simultaneously, assuming the plungers to be initially in normal positions. The winding 156 may be arranged so that the hard water system would be the preferred system.

From the foregoing description, it will be apparent that there are provided two pumping systems, each connected with independent sources of supply, each system comprising a pump, and a common prime mover consisting of an electric motor for actuating the pumps, the driving connections between the prime mover and the pumps being dependent on the direction of rotation of the prime mover. Only one of the pumps may be operated at the same time, a demand in one system having no effect on the other system in case the other system is in operation at the time the demand arises. The demand in the second system stands in waiting until the demand in the first system has been fulfilled, but immediately upon fulfillment of the demand in the first system, the direction of rotation of the motor 60 is reversed and the second system is brought into operation in response to the waiting demand in that system.

In the embodiment of the invention elected for illustration herein, the motor is described as a series motor and the reversal thereof is accomplished by reversing the direction of the field current therein. It is to be expressly understood, however, that as regards the motive power employed and the reversal thereof, the invention is not limited to the use of a series motor nor to the reversal of the field current, but is equally applicable to any other type of prime mover or to electric motors having other than series characteristics, and that when an electric motor is used it may be reversed by reversing the current through the field or through the armature or through both as is well understood by those skilled in the art.

\Vhile the form of mechanism herein shown and described constitutes a preferred embodiment of one form of the invention, it is to be understood that other forms might be adopted and various'changes and alterations made in the shape, size, and proportion of the elements therein without departing from the spirit and scope of the invention.
