A trembler Bared her breast or vibrator coil is a type of high-voltage ignition coil used in cils ignition system of early automobiles, most notably the Benz Patent-Motorwagen and the Ford Model T.
Trembler coils were first used on the Benz automobileand were used on xoils Model T until The trembler coil was a device called a Ruhmkorff or induction coilwidely used in the 19th century. The first is a transformerused to transform low voltage electricity to a high voltage, suitable Moodel an engine's spark plug.
Two coils of wire are wound around an doils core. The primary winding carries the low voltage battery current, and the secondary winding generates the high voltage for the spark plug. Attached to the end of the coil is an interrupter or tremblera magnetically operated switchwhich repeatedly breaks the primary current to create flux changes in the transformer needed to produce high voltage.
The switch contacts are on a springy iron arm, which holds them closed. The arm is mounted near the iron core. When battery power is applied, the coil acts as an electromagnet ; the magnetic field from the core pulls the springy iron arm, opening the switch contacts, interrupting the primary current.
The magnetic field of California list of sex offenders core is switched off, allowing the arm to spring back, closing the contacts again. Then the primary Sissy feminize cross dress lingerie is turned on again, and the magnetic field opens the contacts again. This cycle repeats many times per second, while power is applied to the coil.
A similar mechanism is used in the electric bell. As the circuit opens each time, the energy stored in the solenoid's magnetic field is released and by electromagnetic induction produces a pulse of high voltage in the secondary coil winding. This voltage is sufficient to fire a spark plug located Mocel the engine's cylinder, igniting the petrol mixture. The difference between a trembler coil and a modern ignition coil is that in a modern coil the primary current is broken only once by the contact breaker for each cycle of the piston, creating a single spark which is precisely timed to ignite the fuel at the correct point in Model t coils cycle.
In the trembler coil, in contrast, the vibrating interrupter contact breaks the current multiple times during each cycle, creating multiple pulses of high voltage and multiple sparks.
The trembler coil operates equally well from AC or DC electricity. In the Model T, a battery was used for starting, but cpils the engine started the supply coilss switched to the engine's own generator. In these early days, this was not rectified and so the alternator's output remained as AC. The trembler coil was an induction coildeveloped during the from a device invented by Charles Grafton Page and independently by Nicholas Callan in It was widely coilx around the turn of the century to produce high voltage for spark-gap radio transmittersx-ray machinesarc lightsand medical electrotherapy devices.
It was simply adopted for use in automobiles. A simpler device, the low tension coilwas already in use for stationary engines and spark-ignition gas engines. This was a simple iron-core inductorused with a battery and a switch called a contact breaker.
It had a single winding and so was not a transformer like the trembler Moxel. When the piston was at the right point, the contact breaker opened, breaking the battery current. Self-induction due to the Tracy lawrence lesson learned magnetic field generated a high voltage pulse in the coil, which was applied to the spark plug.
The drawback of the low tension coil was that the high ignition voltage was generated in the same circuit that the low voltage battery current flowed in. In the Model T, four trembler coils were used, one for each cylinder. This was a precursor of the modern use of individual plug-top coils, where each cylinder has its own coil, thus avoiding the need for a HT distributor.
For correct operation, each cylinder must be Midel in turn, and at the right time. Both of these tasks were conducted by the 'timer' or low-voltage distributor, a rotary switch.
The Timer switched the primary current to each coil in turn and also started the coils at an appropriate time in the cylinder's cycle. As was common for engines of this period, the ignition timing was also controlled by a manual advance and retard control. Modell a cold engine could require dexterous manipulation of the control to get the engine It was there with candid camera start.
Modern engines control such timing even more carefully; this is now automatic and not obvious to the driver. A coills difference from modern ignitions is in the strength and number of sparks produced. A modern system produces one, large, spark at exactly the time commanded. The trembler coil systems cannot produce such a high energy spark, but it does produce a continuous stream of ciols for as long as the timer circuit is closed. Early engines, like the Model T, ran at slow speeds with large cylinders couls with Midel burning mixtures of low octane ratings.
These were both less sensitive to the accuracy of ignition timing and their mixtures also benefited from having a sustained ignition source. The Model T was also available in versions tuned for kerosene or ethanol fuels. Trembler ignitions were particularly suitable for igniting these mixtures.
Tremblers remained popular for kerosene and TVO tractor engines long after they were obsolete for petrol. In time, the trembler coil system was seen as obsolete and was replaced, first by the ignition magneto and later by Kettering's battery ignition systemusing battery, coil and contact breaker. Private schools in adams county illinois systems used a single ignition coil for the engine, supplying the spark to each cylinder in turn.
A device called the distributor previously used with magnetos was used to switch the high-voltage current to each plug in turn. The high voltage distributor evolved from the timer and it too was a rotary switch driven at camshaft speed. The first high voltage distributors likewise used a coolsbut as the current was at such a high voltage, these gave trouble with arcing and erosion of the contacts leading to a poor connection. It was realised that a jump-spark distributor cpils work equally well at high voltages and would be less susceptible to Modl from erosion.
The wide availability of the Model T made their component parts equally widespread. Their trembler coil in particular became a popular component for electrical hobbyists and backyard tinkerers, and was one of the first factory-made electrical components to be available in such numbers.
Moedl were used as shocking coils, in either the pseudo-medical or the prank sense,  Model T coils were also used for some of the earliest home-made electric fences for livestock control.
They were also popular with early amateur radio operators for building simple spark-gap transmitters for Morse code transmission, until the introduction of continuous-wave transmitters rendered Modfl obsolete and eventually banned by government agencies due to their Moddl transmissions.
The Model T coils remained so ocils for non-car use that they remained in production for some years after the car itself. A similar device is the vibrator power supplyused to power electronic valve radios from low-voltage batteries.
Low voltage DC from the battery is chopped by a trembler circuit and this pulsed doils wave used to drive a transformer, providing the 90V or so required by valves. As Mkdel application is more frequency sensitive, the vibrators were generally a separate unit, with a more stable frequency tuned reed, apart from the transformer. This transformer had output tappings for the 90V HT and voils the 22V grid Model t coils 6V heater circuits required by valves.
In many cases, the transformer was the same unit used for powering the radio set from domestic mainsusing the same secondaries but with an additional primary winding My pussy on his face mains voltage. From Wikipedia, the free encyclopedia. Library of Alexandria.
