Thepowerdirectors26arepreferablyspringloadedelectricalswitchingdevices,andareconstructedtobeabletotransferlargeamountsofelectricity.Thepowerdirectors26mustalsobeconstructedtoresistarcingsothattheycanoperateforanextendedperiodoftimewithoutbeingreplaced.

Inthepowerdirector26,thecontactrod30isattachedtothecontactplate32.Aspring34urgesacontactrod30againstthecrankshaft10sothatthecontactplate32doesnotcontactthecontacts36aand36bexceptwhenurgedupwardsbytheeccentriclobe28.

ReferringnowtoFIG.6,inasecondembodiment,thereciprocatingelectricalmotor200comprisesalowpowerdistributionassembly38connectedtoalowpowersource40.Thelowpowerdistributionassembly38isconnectedtothelowpowersolenoids42whicharearrangedtodistributehighpowerfromthehighpowersource4tothesolenoids8.

Thelowpowersource40ispreferablyatwelvevoltdirectcurrentdeepcyclerechargeableleadacidbattery,preferablyselectedtobelightweightandcapableofstoringsufficientelectricalpowertofunctionforseveralhours.Mostpreferably,thesecondpowersource40isconstructedtohaveanoperationaldurationroughlyequivalenttopowersource4.Insteadofutilizingtwopowersources,itisalsopossibletouseonlyonepowersourceandstepdownthevoltagesuppliedtothesecondpowerdistributioncontrolassemblythroughresistorsorotherappropriatecircuitry.

ReferringnowtoFIG.8,thelowpowersolenoids42arepreferablylowvoltage,lowamperagesolenoids.Solenoids42haveawirecoil44disposedinsideaframe46andacore48disposedwithinthewirecoil44.Thelowpowersolenoids42preferablyareinternallywiredintheconventionalmanneroritsequivalent.

Aspring50isdisposedinsideofthelowpowersolenoid42betweenaframe46andoneendofthecore48.Whenthelowpowersolenoid42isnotinelectricalcommunicationwiththelowpowersource40,thespring50biasesthecoreoutwardawayfromtheinsideoftheframe50.Aspring52maybedisposedbetweenanendcap54toassistthespring50inbiasingthecore48awayfromtheinsideoftheframe46.Thesprings50and52areshownincompressionandtensionrespectivelyinFIG.8.

Whenelectricalenergyissuppliedtooneoftheterminals56ofthelowpowersolenoid42,thewirecoil44isenergizedformingamagneticfieldandpullingthecore48intothevoidagainstthebiasingforcesofthesprings50and52.Thecontactplate57isattachedtotheendofthecore48.Whenthecore48movesintothevoidofthewirecoil44,thecontactplate57contactshighpowerterminals58and60toformanelectricallyconductivepathbetweenthem.

AsshowninFIG.7,thelowpowerdistributioncontrolassembly38hastines62attachedtotineterminals64distributedcircumferentiallyaboutcrankshaft10.Acontactbar66isdisposedonthecrankshaft10suchthatuponrotationofthe

Thetines62preferablyareformedfromflexible,yetresilient,piecesofmetal,howeverothersuitableembodimentsmayalsobeused.Thetines62arepreferablymadeofcopper,butanysuitableelectricalconductivemaybeemployed.Thecontactbar66mustbeattachedtoinsulatingmaterial,suchasplastic,whichisboltedtothecrankshaft10orsecuredinanyotherconventionalmanner.Lowpowerpositivecable68isattachedtothecenteroftheinsulatingmaterialinsuchamannerthatanelectricallyconductivepathisformedbetweenthepositivecable68andcontactbar66.Thiscanbeaccomplishedbyawiredisposedwithintheinsulatingmaterialboltedtothecrankshaft10.

Itmayalsobepreferabletodistributeelectricitythroughanelectricallyisolateddistributorattachedtotheendofthecrankshaft10,orconnectedtothecrankshaft10viaachainorsimilarconnector.Becauselowpowerisbeingdistributedbythelowpowerdistributioncontrolassembly38,anordinarycardistributormaybeusedinsteadifappropriatelymodified.

AsshowninFIG.9,thepositiveterminalofthelowpowersource40isconnectedtotheinsulatorboltedtothecrankshaft10viaalowpowerpositivecable68.Whenthecontactbar66contactsthetine62,electricityflowsthroughlowpowerconnectioncable70,activatesthelowpowerdistributionsolenoid42,andflowsbackthroughthelowpowernegativecable72tolowpowersource40.

Uponactivationofthelowpowerdistributionsolenoid42,anelectricallyconductivepathisformedfromthepositiveterminalofthepowersource4,throughthepositivecable16,thelowpowerdistributionsolenoid42,theconnectioncable74,thesolenoid8,thenegativecable14andbacktothenegativeterminalofthepowersource4.Thiselectricallyconductivepathenergizesthesolenoid8,causingthecore18tobepulledintothevoidinthebody20,therebyexertingaforceoncrankshaft10throughtheconnectingrod22.

Thus,thelowpowerdistributioncontrolassembly38controlsthetimingofthefiringofthecontrolsolenoids42whichinturncontrolsthefiringofthesolenoids8.Byusingtwosetsofsolenoids,highpowerhighamperageelectricitymaybeefficientlydistributedtothehighpowersolenoids8withoutburningoutthecontactpointsoftheswitch38.Becauselowpowerisdistributedbyarotarytimingmechanism38,therotarytimingmechanism38doesnottendtoburnout.Becausethelowpowerdistributionsolenoids42havecontactswhichrapidly,linearly,switchbetweenthe"on"positionandthe"off"position,thehighpowerswitchesdonottendtoarc,andthus,anelectricalmotorutilizingthisformofswitchingmechanismdisplaysenhancedresistancetomechanicalfailureduetocontactburnout.
