Experts testing Chalmers motors for silence and power Drawn from life by H. L. Grout Silence is merely absence of noise. Some automobile motors are silent simply because the noises are covered up-muffled. But the friction, the iiii grind which causes noise is there just the same; wearing away at the life of the mechanism. Chalmers motors are silent because they are rightly designed and built; because the causes of noise are removed. At high motor speeds you can balance a pencil on end on the radiatorcap of any Chalmers "Six" motor. That's because all working parts are accurately balanced. In a long hard pull through sand or up a steep hill, the Chalmers motor does not grind or protest against the load. That's because all parts are accurate to 1/1000 of an inch, eliminating friction. After seasons of use, your Chalmers motor runs as sweetly and develops as much power as when new. That's because it is built of the best materials gand designed for long service. And these qualitiesare in every Chalmers motor. We prove it before a motor is put into a car; by long runs. "under load" with an expert always looking for defects. The Chalmers motor test S department, a part of which is pictured above, is equipped with the latest scientific devices for detecting faults. Only motors which are right in every detail can survive the trials of the Chalmers " block test." Because all parts of a Chalmers car receive the same rigid tests-because the whole car is proved before it leaves the factory-the Chalmers owner MI knows little about the insides of his car. He is conscious only of a continuous readiness for any service he may ask of his "Quality First" Chalmers. 'i I' "Chalmers Doings" No. 35 contains all facts about 1915 Models.
