Definitions

  • My invention relates to improvements in low voltage starting systems on high voltage service mains and it pertains more especially to the features pointed out in the annexed claims.
  • the purpose of my invention is to provide a low voltage starting system operable on ordinary high voltage service mains; to use a low voltage starting motor that may also act as a charging generator; to provide antomatic means for switching the mains from the high voltage generator to the low voltage starter; to provide a series coil on the service circuit to control the ignition system and also separately open and close the starter circuit; to provide a storage battery automatically chargeable from the low voltage starter acting as a generator; and to also effeet the charging of the storage battery from the high voltage generator through an interposed resistance.

  • Fig. 2 is a diagrammatic view similar to Fig. 1, showing the parts, circuits, etc., in starting relation;
  • Fig. 3 is a similar view to the running relation
  • Fig. 4 is a detached view of a self-protectin switch applied to the service coil
  • i 5 is a detail sectional view of the switc plate thereof.
  • an engine 1 preferabl of the multi-cylinder type, has its shaft 2 irectly connected to a normal or high voltage generator 4 by means of an ordinary coup ing 3, and a similar coupling Fig. 1, showing W. BUCHElt, A
  • magneto 34 supplies ignition current through wires 61 to the spark plugs of the engine and is connected to the engine in any suitable manner as by means of a chain 33.
  • the primary winding 35 of the magneto is grounded at one end, 62, and'the other or interrupter end is automatically connected to or disconnected from the ground by a switch 21 connecting Wire 58 with a grounded contact point 23.
  • the secondary winding 36 of the magneto is grounded at one end and the other end is connected to a distributor in the usual manner. This specific relation of parts is immaterial as a battery system would be a practical equivalent of the magneto.
  • the primary winding 35 is grounded so that the interrupter, not shown, is short circuited to render ignition inefiective by the wire 58 and its closed switch 21 when the engine 1 is to be stopped, and it remains grounded so long as the engine is idle.
  • a hand switch disconnects wire 58 from the control switch 21 whenever such disconnection is desired.
  • the starter 5 is set into motion by means of current at a low voltage from battery 9 whenever a lamp 37 or other translating device is connected by switch 38 across service mains 39 and 40.
  • current will flow from the battery past point 45, over wire 52 to point 23, switch lever 25, service wire 40, lamp 37, switch 38, the other service main 39, solenoid 11 to the battery over wire 54.
  • This very weak current is adequately strong to energize the solenoid 11 so as to move the core 12 with attached link 15, magneto switch lever 21 and starter switch lever 22.
  • This movement breaks the magneto current at 23 to render ignition efi'ective and closes the starting circuit at 24 when a heavier current will pass from the battery 9, past junction 45, starter 5, emergency switch67, over wire 56 to point 32, over switch lever 31 and the other part of wire 56 to point 24, passing an emergency manual switch 66, over switch lever 22, wire 57 to point 43, wire 53, point 44 and back to the battery.
  • the starter will now be in operation and in a few moments the engine will have come to speed, causing the generator 4 to establish a potential in wires 50 and 51 dependent on the shunt resistance 10 of its field circuit. Current at this potential will flow over wire 51 past pointi49, manual switch 63,
  • solenoid 6 over wires 60 and "past point 48 and back to the generator by wire 50, thus energizing solenoid 6 to move its core with attached link and switch levers 25, 26 and 31 into the position shown in Fig. 3.
  • the generator current will be delivered to the service mains 39 and 40, the switch lever 26 serving to connect service main 39 with generator terminal Wire 51 and switch lever 25 serving to connect service main 40 with generator terminal wire 50.
  • the solenoid 11 being included in the service main 39 will remain energized so long as current passes through the mains, which will be as long as the demand for service is made. For re-charging the battery from the generator 4 a path of current flow may.
  • the switch 31 may be connected with or detached from the core 7 of solenoid 6 and when so connected the starter 5 is not cut ofi from the battery 9 until the generator 4 delivers its current at its rated voltage. Dependence is then placed on the resistance 41 to reduce the voltage of the re-charging circuit through the battery while the battery is being re-charged by the generator 4, as above traced.
  • switch 68 would be opened and switch 31 would be disconnected from the core of solenoid 6, keeping the circuit closed at this point and controlled entirely by switch 22.
  • This recharging circuit may be traced from starter 5 acting asa generator, through wire 56, switch 31, wire 56, switch 22, wires 57 and 53, through battery 9 back to generator.
  • the switch 22 remains closed so long as there is a demand for current on the service mains 39 and 40. When the service demand ceases there is no current flow through solenoid 11 and it becomes deenergized, causing its core to drop and move the switches 22 and 23 back to the position of Fig. 1 so that switch 21 grounds the magneto to stop the engine and at the same time switch 22 opens.
  • Links 15 and 59 may be insulated between the several switch levers in any desired manner.
  • manual switch 68 to control the battery charging from generator 4
  • a manual switch 64 in the generator circuit and similar switches 65, 66 and 67 are pro- 'vided for testing and other purposes.
  • the solenoid 11 is composed of two coils one of which forms a fine wire winding 20- of many turns to do the work of moving the switches 21 and 22 under the weak low voltage current from the battery when demand is made on the service mains and the other forms a comparatively larger wire winding 19 of much less resistance and brought into parallel relation with the coil 20 when the switches have been moved and serving to retain the switches in their moved position not only during the short remainder of the time that the battery continues in circuit but throughout the time that the generator suplies the service mains and until there is not urther demand for service on the mains.
  • the low resistance winding 19 is closed in parallel with the high resistance winding 20 by the engagement of a contact disk 16 on the solenoid core 12 with contacts 18, thus bridginga break in the coarse wire winding.
