Oscar Lear

The Oscar Lear Automobile Company was from Columbus, Ohio. In 1904 they produced an air-cooled, a four cylinder, 24 HP Touring Car (with the engine designed by Lee A. Frayer and William J. Miller) called the Frayer-Miller that sold for $2,500. It had three speeds forward and a reverse, sliding gear transmission, bevel gear drive with no pump, radiator, water tank or piping.

Text from a 1906 ad.
AN AMERICAN PRODUCT. IMITATION OF NO FOREIGN CAR.
THE system of cooling in the Frayer-Miller Car really marks an epoch in automobile gas engineering. There is nothing to compare with the FRAYER-MILLER AIR-COOLING SYSTEM. It is distinctive. A Frayer-Miller Car covered more miles in one week than any other type of self propelled vehicle.

The Frayer-Miller Car at Long Branch was driven 3,202 miles in 6 days, 15 hours and 29 minutes, equal to the distance from Golden Gate to Hell Gate. During the last 1,866 miles of this trip the engine never stopped.

Records for distance and for endurance.
The Frayer-Miller with its novel and striking air-cooled system is up-to-date and always successful. No water-cooling system would ever be necessary with the Frayer-Miller, or air-cooling system through air jackets possible with other makers. The mud guard arrangement is novel and new.
