THE ELECTRIC HORN

Of all the appurtenances which go to make up the sum total of a car the electric horn is the least likely \o go wrong. Simplicity is the "keynote" of its design, no matter what particular model is favoured. And, as befits its make-up, it is perfectly easy to dismantle on the rare occasions, when such an operation becomes necessary. However, when the electric horn fails to act, it always seems, by some mysterious dispensation of providence, to select a moment when its services are most needed. The troxible may not be in the horn proper at all, but is sometimes caused by the wires from the battery getting lodged behind the horn motor cover, with the result that constant vibration causes the insulating material of the wires to fray. The trouble might happen from other causes not connected with the interior mechanism of the instrument; for instance, in the battery iteself, or from faulty contact in the push button. All these little faults are easily located' and can be as easily rectified. There is one thing that should never be forgotten, and that is to give the motor a few drops of oil, say three drops a month. So far as the actual interior of the instrument is .concerned, the only attention required (and that exceedingly rarely) is to clean the I brush bearing of the armature with a 'rag. Sometimes it will be found that the carbon brushes need to be faceu up.
