In internal'combustion'engines fitted with an electric starter, the accumulator battery connected to the dynamo usually has a voltage of 12 volts, and under certain circumstances even 24 volts.v If electrically heated incandescent wire plugs are used for ignition, particularly on starting, and these, are connected up to such accumulators,.it necessary to insert in the accumulator circuit 1b a resistance in series with the incandescent wires owing to their low resistance, and this causes a considerable loss ofenergy from the battery during the discharge eriods. In order to avoid this loss the incan escent-wire plugs are, according to the invention, su s plied from an additional accumulator, t e voltage of which is lower than that of the accumulator battery provided for the starting motor, and which is connected to the dyao namo through an automatic switch and a voltage reducing element.
Three to s of construction of the invention adapted for use on motor vehicles are shown in the accompanying drawings by way of example. I r f v Figure Ishows the wiring diagram eta system having twoautomatic switches. Figures 2 and 3 show the wiring diagrams of two difierent systemshaving a single autoso matic switch. v InFigure 1 the system consists of the dyn'amo 1, the starting motor 2,- switch box 3, lead plate accumulator battery 4, supplying current at for example 12 volts tential, the two head light "lam 5 and t e automatic ,Qswitch 6 between e dynamo land the switch box 3. An-aocumulator battery consistin of two Edison cells 9 connected in pa el, the ave discharge volta of which amounts to 1. volts, is contact; with the dynamo through a second automatic switch -7 and an incandescentlam 8. incandescent .wireignition plugs 1 are con- 9,-9 through a handoperated switch 10.
The incandescent lamp 8 reduces the volt-' age of'the current supghed by the dynamo 1 to tke value-suitazahlerBthe 1two eelltigtatilild attesametime ows ygowing e leeells9arecharged. a I
289,166, and in Germany July 14, 1927.
The two Edison cells 9, automatic switch 7 and incandescent lamp 8 are preferably the side of the vehicle as a single Figure 1, are replaced in Figure 2 by a single automatic switch 12, the armature 13 of which carries'two contacts 14 and 15 separated by common contact 16 is connected up with the dynamo 1.
Figure 3 shows a' further system in which an ordinary automatic switch is used in con junction with a switch box ofthe type usual inmotor vehicle, illumination. Two conan insulated member 17. The contact 14 is tacts 18 and 19 are provided in the switch box 3 on the lead passing from the automatic switch 6 to the main accumulator battery 4 and two terminals 20 and 21 are also provided therein, the terminal 20 being connected to the lead through the lamp 8 to the auxiliary accumulator 9, and the terminal '21 to the lead from the starting motor 2 through a starter press-button switch 22. Contact springs 23 and 24 are provided which are adapted to cooperate with the con tacts 18 and 19. The two contact springs 23 and 24 are actuated bymeans of a cam 26 rotatable about an axis 25. In the open position shown, the two contact springs 23 bearing against the switch cam 26 are awa from their res 'tive contacts 18 and 19' so t at the leads to th the starting press button switch 22 and also to the auxiliarybattery 9 are cut out. I v
When the switch cam, 26 is turned through 909, the two contact springs 23 and 24 are forcedagainst the contacts 18 and ,19 and the engine can be started by de ressing thestarter button 22 after closingtiie incandescent plug switch 10. As soon as the engine has started, the starter button 22 is again released whilst the plug switch 10 for the incandescent wire plugs remains closed until the engine can run on self-i 'tion.
' On stetapping the engine t e switch 25, 26 is. turn ac shown, so t the main-accumulator b hand .to the position of battery 4 cannot discharge through the auxiliary accumulator 9.
This arrangement ensures that the auxiliary ,o,ccumulator 9 can be charged while the engine is running. When the engine is at rest the glowing of the lamp 8 indicates that the switch 25, 26 must be turned oif.
A single larger Edison cell or a lead plate cell maybe used instead of the two Edison cells. When using the lead plate cell a suitable small resistance is preferably inserted before the incandescent wire plug owing to its slightly higher Voltage.
