Show ALARMWARNSOF j DEFECTIVE TIRE I Etotrta Device Invented by In- I tfanapoNs Man Can Be At I taehed to Any Whetl. I ELECTilIC SWITCH DOES WORK I Placed In Position 8o That They WIM I Be Thrown to Oryo or Other, of I Closed Positions When Tiro I Is Punctured. It frequently happens that air leaks I dowly from a tire without the driver's I knowing It. The tire becomes flat and I the rims of the wheel cut Into It. To I warn drivers In time, fieorge V. Young I of Indlsnupolls has recently Invented an electric alurm which can be at- I tached to any wheel. It consists of an I electric switch which Is mounted on I the axte of a wheel. The blade of I this switch projects toward the spoke I of the wheel. The end of the blade I stops very close to the spokes, thougn I enough space Is left to cuahlo the I blade to barely clear them. I Working of 8wltch. 1 Working In conjunction with tha I blado of the switch Is a metal finger I mounted on one of the spokes of tho 1 wheel. This finger can slide radially I to the wheel, but a sprlug normally I holds It away from the axle, with one I M(V1 WW trnxn M I -r ss 1 1 A Flattened Tire Presses a Switch- I finger Inward. The Electric Switch I Is Thus Closed, and an Alarm in tho I Circuit at Once Qlves Warning. I end up against the underside of the I Inflated tire. The other end of the I finger will clear the projecting blade 'I when the tiro Is properly inflated. Just j I as soon as the tire begins to flatten, ' I the finger Is pressed radially Inward I and It strikes against tho projecting I blade. Tho switch Is thereby closed I and an alarm, such as a well located I light or buzzer which Is very easily I heard, is operated. -. I |
