THE RICHMOND PALLADIUM AND SUN-TELEGRAM, SATURDAY, SEPT. 27, 1919. PAGE NINE The Automobile Simplified By FREDERICK C. GUERFKJCH, M. E. Make This Your Automobile Correspondence School AN intimate talk on the porting tmlU f the automobile discussed In inch a way that the layman can easily understand them. If In reading these articles, as they appear in the Palladium each Sat urday, there is anything not clear to yon. as'C Mr. Guerllch about It An answer will be published on the completion erf the articles on the section of the automobile under discussion. Copyrighted, 19 IT, By Frederltgc C. Guerrllch. LESSON NO. 30. The Duplex System. There has recently been brought out, a combined high tension magneto and battery system of Ignition, called the Duplex System; which because of its low first cost and simplicity, may be the system of the future. Should the magneto again become as much hare bn perfected step by step, and how or ft improvement led to another is cleaily seen in the development of the vailous magneto systems of igni tion. TJhus we first had the low ten sion mt.gneto with Its outside coil; then wi) had the high tension mag neto, wliich is the result of inventors observing that the magneto armature L " u U'h Fig. 1 Mm 'Cu.ii used as it was about two years ago, the Duplex System will be the Bystem most used. It therefore, is entitled to rxplanation. The automobile and its accessories and its windings could be used in place of tUie coil; next we had the dual system, designed in order to make starting masier, but again making mat ters complicated and bringing back the induction coil; and now we have the duplex system, and in this it is plainly seen how the step taken In designing the high tension magneto led to the design of the duplex sys tem; as, here also the Inventor, in his desire to do away with the Induc tion coil, observes that the magneto armature has all the parts of an in duction coil, and uses It in place of the induction coil of the dual system. Let us develop the duplex system. Again, in Fig. 1, I give you the wiring of the high tension magneto. What we want to do is to connect the bat tery to the primary of the armature so as to use the armature core, with its primary and secondary windings, in place of the Induction coil. As the magneto primary Is grounded on the one end, we cannot connect to it on the grounded side of the inter rupter points, and must therefore con nect between the armature and the in terrupter. The wire for grounding, to stop the magneto secondary being gen erated, is also connected here, so let us simply connect to this wire, as shown by the dotted lines. (Ignore the dot and dash lines for the pres ent.) Current from Battery. You will observe that when the in terrupter points are closed the cur rent will come from the battery through wires C and B to the point F, where It will divide and some go through A and the armature winding to the point K where this winding is grounded and so back to the battery; while the rest will go across the inter rupter points and so to the ground. As the primary winding of the arma ture offers a great resistance to the flow of current, while the Interrupter offers practically none, only a little will go through the winding, and most ly all through the interrupter. Thts means that when the Interrupter points are closed the battery current will have practically no effect, it simp ly flowing from the battery to the points, and so back to the battery. Now let us see what will happen the moment the interrupter points open, which is also the moment the piston of the engine is ready for the spark. As the points re opened the battery current cannot go across them to the ground, and therefore all of the current must go by way of A to the armature winding. Thus you will note that the current v.lll now be flowing from the battery to the armature coil, as it does in the distributor system, the armature real ly taking the place of the Induction coll. In order to cause an Induction of a high voltage current in the sec ondary winding, however, the primory current must be interrupted. Thus, some device must be added for inter rupting this current. The magneto in terrupter, obviously, cannot be used for this purpose. The simplest way to overcome this difficulty is to put a vibrator coil sim ilar to those used on your door bell, in the circuit. The dot and dash lines show the course of the current, as It win now flow, as instead of going from i the battery through the dotted line C it will go through G to the vibrator coll and then through H to B, and so as before. Fig. 2 gives the wiring of the du plex system, with the switch, neces sary to stop the engine, or to swing to the battery for starting, and to magneto after starting. Reviewing the action, we find that when the switch is thrown to neutral, the battery circuit is open, as it can only go to the point "2" of the switch, while the magneto primary is ground ed, it entering at 1 on the switch, and then passing through 5, 8, 7 and 3, and so to the ground. Thus no high voltage current will be induced in the secondary, and there will be no spark. When the switch is thrown to bat tery for starting, the segments 1 and 6 of the switch will touch and so will 2 and 5, and you will see that the cur rent can go from H through 2, 5, 6 and 1 to wire B. Thus the current , will flow from the battery through O, then through the vibrator points, through H. then the switch, and finally B. When the interrupter points are clos ed the current will go through thpm to the ground. The moment they open, however, the current will go through the armature, and so Induce a high voltage current in the second ary winding, and thus e-lv th ronnir. ed spark. Note how the interrupter puiuis nuie me sparit. After the engine has started the Switch is thrown to mamctn In tVito in ljii.) case the segment 1 of the switch will not be in contact with any metal por tions of the switch, the point 8 being auuui. alongside ot it. Thus B is dis connected, as it should be when run ning on magneto. As the vibrator makes and breaks the circuit many times in a second, ther will be many shots of high voltage current in the secondary, and so there will be a sort of shower of sparks at the pings. A the lighting system of many cars is such that the battery is not grounded, arrangemnet is usually made on the switch for taking care of this. In this case, instead of the bat tery being grounded, a wire, as shown by the dotted line, is run to the switch. The vibrator coil and the switch, which are not very expensive, can be very easily connected to any high- tension magneto. In many cases thefr addition will help to make starting easy. Motorists Pa IP ectory Food From Air Is Next Process, Soys Expert NEW YORK, Sept. 27 Food may be obtained from sunlight, air and water, according to a recent discovery of Dr. Winthrop John Vanleuven Osterhout, professor of botany at Harvard uni versity. V The process of the food-making is as yet limited to the laboratory stage. Prof. Osterhout points out, but It is possible, to place it on a commercial basis. "Analyzing food, we learn that the three chief components are sugar, fat and protein." he said. "Until recent ly it was impossible to manufacture sugar synthetically, but now we have solved the riddle in several different ways. Next War is Near, General Glenn Says CH1LLICOTHE. Ohio. Sept. 27 De claring that the next war will come sooner than any one expects Major General E. F. Glenn, commanding Camp Sherman, today attacked the League of Nations covenant in the treaty of peace with Germany, assert ing that France's condition was not as bad as the French race would have the world to believe. While he insisted that he was first of all an army man and that it was his duty at all times to stand by his gov ernment and his flag, he emphasized the fact that he did not desire any of ficer or man under his command to gain the "erroneous impression that we should help France out at the cost of the perpetual hatred of the German public."
