I took a magneto off an old car and changed the wiring in the inside so it would put out an alternating current instead of a jump spark.
It had no battery; a magneto fired the plugs to make the engine run and a presto gas tank on one running board furnished gas for the headlights.
The same old Dodge that ran over Albert and killed the hen for supper had a magneto that kept giving trouble, and it cost a fortune to have it repaired each time.
A magneto test for grounded armatures is not to be recommended, as armatures often possess sufficient static capacity to cause a magneto to ring even though there be no leak.
To enable him to do this his machine was fitted with Captain Lefroy's new receiving set in which magneto disturbances were screened off and the signals strengthened by Brown relays, that is, microphones invented by Mr. S.
The set of wireless for the Gamma had to be improvised from odds and ends--an old magneto and some Moscicki jars.

With magneto sets, waystation agents sometimes call each other direct and neglect to record the call and to remit its price.
The next important step in the development of the magneto multiple switchboard was that which produced the so-called branch-terminal board.
Nevertheless there is a field for magneto multiple switchboards, and in this field it has recently been coming into increasing favor.
The operation of the system aside from the busy-test feature is just like that described in connection with the simple magneto switchboard.
As a central-office equipment is required to ring many subscribers' bells, only the small ones find it convenient to ring them by means of hand-operated magneto generators.
In connection with the assembly of these magneto multiple switchboards, as installed by the Monarch Company, Fig.
Were it not for the necessity of providing for cord-circuit signals in common-battery switchboards, the common-battery cord circuit would be scarcely more complex than that for magneto working.
In a small magneto exchange, the transmitter current may be had from primary batteries, a separate battery being employed for each operator's set.
Usually a magneto private branch exchange works in conjunction with a magneto main office, but this is not always true.
It must not be supposed, however, that the common-battery system always has advantages over the magneto system, and that it is superior to the magneto or local-battery system for all purposes.
The voltage of the magneto is a constant one, and is thus better adapted to meet the needs of ignition.
Now, the primary difference between the magneto and the dynamo, is that this field bar is a permanent magnet in the magneto, whereas the field is only a temporary magnet in the dynamo.
With the magneto it is necessary to have a three-point switch, R, and a plain coil S is placed between the switch and battery.
The magneto has a pronounced advantage over the dynamo, as a source of power for ignition purposes, in the particular that the strength of the magnetic field is constant.
One side of the magneto T is connected by wire U with one of the points of the switch R, and the other side of the magneto is connected with the metal of the engine, which is indicated by the dotted line V.
This, of course, cuts out the battery, and the engine is now running on the magneto alone.
As stated, a magneto is a special type of dynamo which will now be explained.
A well-known type of alternator is the magnetomachine which sends shocks through any one who completes the external circuit by holding the brass handles connected by wires to the brushes.
I was not in the least afraid that the magneto would be reported at a point so distant from the one I had taken it from, but I did know that I couldn't "stand up" for two minutes in any kind of interview with the police.
The ten or twelve-pound magneto would be a good deal of a nuisance, but, as the possible sale of it at some distant point offered an easy way to the money I was sure to need I decided not to let it go till I had to.
Two seconds later I was snuggled up on the "bumpers" with my wrench and magneto in my lap.
The magneto was worth something like a hundred dollars, and even if I had no chance to sell it, it was a pity to overlook so easy a bit of "strafing.
The magneto slipped out of my two-fingered hand as I jumped off, and brought up in the frog of a switch with a jolt that must have played hob with its delicate insides, but I wasn't doing any worrying on that score.
Then I cut off with a knife a good-sized square of the canvas paulin that covered the machine, wrapped the magneto in it, and tied up the bundle with a piece of the insulated copper wire, leaving a doubled loop for a handle.
So I told old Fritz to go ahead and telephone, and as soon as his back was turned grabbed up the magneto and slipped out to the street as quietly as possible.
A single camshaft operates not only all of the inlet and exhaust valves, but the magneto and gear water pump, as well.
He knows, then, that the magneto is driven positively and that there is a constant relation between its speed and the number of revolutions of the motor.
To be sure, themagneto is delicate, and for that reason it should never be dissected by the amateur, but inasmuch as what few adjustments it has are readily accessible, it is seldom that the machine need to be taken apart.
The positively-driven, alternating-current magneto may also be used to operate electric lights on the car, but this type of current cannot be stored in a battery, and consequently the lights are available only when the motor is running.
It has been stated in a preceding paragraph that the voltage produced by the average battery set will not exceed nine or ten, and even the pressure generated by the ordinary magneto is not greater than this.
The coil and batteries or magneto by no means form the entire ignition system, although the generation of the spark depends entirely upon them.
If the magnetohas been disconnected from its driving gear for any reason, the amount of magnetism remaining in the fields will be best determined by turning the armature shaft with the hand.
Our improved Magneto or Dynamo for producing current to operate the Stop Motions is designed on the "Induction" principle, so that the current is generated in the stationary winding, and no brushes or collectors are needed.
One part, shown with double cross lines, is connected to the Magnetothrough the down-rod A, and the other part through the down-rod B.
Magneto does not generate) by moistening the tips of the fingers and touch terminals of magneto.
If the bell does not ring and the magneto turns hard, (1.
Operator's test: With the receiver on the hook turn the magneto handle briskly.
Open the magneto box, see that contact is made between shaft and spring at U and between the springs at V when the handle is turned.
The magneto of an aeroplane performs a service similar to one in an automobile.
The two lads frantically began work, and they soon had the magneto in running order.
The dynamo and magneto were doing much more efficient work since Tom had put the new platinum in, and the Falcon was making better time than ever before.
The young inventor took in every bit of machinery in a quick glance, and he saw at once that the main dynamo and magneto had short-circuited, and gone out of commission.
If the earth wire of a magneto makes a metallic contact there is trouble in the cylinders, so Simmonds is switched off until he can locate the fault.
Stick a pin through the earth contact of your magneto and jam it against a cylinder, or something of the sort.
Even when the cover was replaced and the tire pumped to the proper degree of air-pressure he lit a cigarette and had a look at the magneto before restarting the engine.
Bell invented the first telephone, which consisted of the present receiver, used both as a transmitter and a receiver (the magneto type).
In 1875 Bell, who as a student and teacher of vocal physiology had unusual qualifications for determining feasible methods of speech transmission, constructed his first pair of magneto telephones for such a purpose.
All through this formative period Bell had adhered to and introduced the magneto form of telephone, now used only as a receiver, and very poorly adapted for the vital function of a speech-transmitter.
One is known as the magneto method and the other that of varying the resistance of the circuit.
One is the magneto method--the one we have described--and the other is effected by varying the resistance of a battery current.
She was writing about magnetos in a way to make you want to drop your customer, or your ironing, or your game, and go downtown and buy that particular kind of magneto at once.
Over beyond some distant sand dunes, the boys had been told, was the establishment of the boat-builder, where they had taken their craft to have a new magneto put in.
The method of ignition which at present seems to be preferred to any other for producer-gas is that employing a break-spark obtained with the magneto apparatus previously described.
Electric ignition is effected in gas-engines by means of a battery and spark-coil, or by means of a small magneto machine which mechanically produces a current-breaking spark.
Magneto apparatus, on the other hand, are noteworthy for the regularity of their operation.
The magneto A consists of horseshoe-magnets, between the poles of which the armature rotates.
Magneto ignition devices are mechanically actuated, the necessary displacement of the coil being effected by means of a cam carried on a shaft turning with half the motor speed (Figs.
The exhaustion of the magnets, which, however, occurs only after several years of use, except when the magneto has been subjected for a long time to a high temperature.
If a magneto be used in connection with the ignition apparatus, its inspection need not be undertaken whenever the engine is started, because it is not so likely to be deranged.
General view and details of a magnetoignition apparatus.
The wire, it must be explained, led from the magneto in a single length, afterwards branching into a number of subsidiary wires to the respective sparking plugs of the cylinders.
By spraying the electric current conductor between the junction and the magneto the whole of the firing was put out of action simultaneously, after the acid had taken time to eat through the guttapercha insulating cover.
By nine o'clock in the evening the adjustments to the magneto were satisfactorily carried out, and the battleplane's wings having been folded to escape an accumulation of snow, the airmen turned in for the night.
My machine was struck several times, and, as bad luck would have it, the patent point of my magneto fell out just when I got to the spot where shrapnel was thickest.
But then my magneto failed me, and I realised what was in store on those wind-torn waters.
I first secured a magneto out of an old telephone, then drove a spike in a damp place under the porch, attached a wire to the spike and ran the wire to one of the poles of the magneto.
I next ran a wire from the other pole of the [Illustration: Wiring] magneto to the can, wrapping the wire around the can several times.
At the same instant I gave the magneto a quick turn, which sent the dog away a very surprised animal.
Care should be taken not to alter the position of the magneto shaft when tightening the nut to secure the gear or coupling, after which the magneto should be secured to its base.
Check timing ofmagneto and see that all brushes are making contact.
The timer on the dual type magneto is adjusted so that the battery spark occurs about 5 deg.
The third available method is to drive the magneto by means of a chain.
The spark-plugs commonly used for battery and coil ignition cannot always be employed when a magneto is fitted.
Set the magneto in the advance position and rapidly rock the engine over the top-center position, observing closely if a spark occurs between the end of the high-tension cable and the frame.
If the magneto is suspected, the first thing to do is to determine if it will deliver a spark.
As the magneto must be driven at a high speed, a coupling of some flexibility is preferable.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "magneto" in a variety of sentences. We hope that you will now be able to make sentences using this word.
