RAY & DAVIS STARTING - LIGHTING SYSTEM EXPERIENCE starting and lighting service for automobiles can be nothing more than a make-shift—an experimental device: The Gray & Davis Starting-Lighting System was the re- sult of intelligent pioneer work—plus the sum of many experts’ experience. Experience in motor car design and construction— Experience in dynamo and electric motor designing— Experience in building, testing and installing such equip- ment— Experience in meeting the specifications of car manu- facturers, ——S A NY electric motor hastily altered and formed into For fourteen years we have produced automobile lamps. Our electric lamps have won international standing. Our entire efforts are devoted to building electrical equip- ment for automobiles. We are specialists in this field; we do nothing else. Five years ago we produced the first dynamo which put the electric lighting of automobiles on a successful and practicable basis. We next studied the application of this same electrical power to the operation of a starting motor and the com- bination of this motor with our lighting system. Jt was a natural progression—not a new problem. Here the experience of our designing and producing staff assumed vital importance. For twenty-two years the chief of our Electrical En- gineering Department designed direct current generators. Sixty per cent of all electric automobiles you see today are equipped with motors designed by him. In adapting our system to different cars, the experi- ence of the head of our Mechanical Engineering Depart- ment was of great value. This man spent years in designing and building one of America’s leading cars. _ The man who superintends the actual production of our automobile equipment has built electric dynamos for fif- teen years. Under him, hundreds of skilled electricians and machinists work in our plant, which is the largest and most completely equipped factory of its kind. | Before leaving the factory, each Gray & Davis dynamo or motor must meet an efficiency test, an overload test, and a fatigue test to determine whether it is possible to break down the system, These tests are 50 per cent more drastic than the worst possible road tests. And afterward—when the system is in actual service on acar, the Gray & Davis Service Department stands back of the motorist. Directing this department is a man who has had twelve years’ experience in electrical service work. Under him are sixty-two Service Stations throughout the country. h one is in charge of a practical electrical expert. One of these stations is within easy reach of every motorist in the United States. Two years’ experience with the Gray & Davis Starting- Lighting System, installed in various makes of cars and operated under every conceivable condition, has proved that it long ago passed the experimental stage and that it successfully meets every starting and lighting requirement. You will find Gray & Davis Starting-Lighting Systems on leading American cars in each of the price classes. Re- member that the makers of these automobiles, like your. self, were buyers when they adopted the Gray & Davis System. They brought their engineering experience into play to enable them to select the best system to offer you as part of their standard equipment. We will be pleased to send catalog on request. CUTTY SS dannneteananaany’ Fret OMT The Gray & Davis Starting-Lighting System consists of a dynamo, a starting motor and connections. It is a 6-volt system throughout. Each unit has its dis- tinct function. The dynamo operates at constant speed. It charges the battery and furnishes current for lighting the starting motor and auxiliary purposes. One press on a pedal operates the starting motor, spinning the engine fast enough to fire on magneto. No “dragging” effect is exerted. The wiring is simple and heavily armored. The whole system is unusually economical in use of current and requires no attention except occasional lubrication and renewal of distilled water to the battery. And the Gray & Davis Starting-Lighting System will outlive any car. GRAY & DAVIS, INC., BOSTON, MASS. OMT {TTT TTT PYYTTTTTT TTT OITA SST a E> aE STATIN rere TITTY IT comicbooks.com
