The 1922 Holmes Series 4 Limousine was innovative for its time because it brought air-cooled engineering into a full-sized luxury car. Instead of relying on a conventional radiator and water-filled cooling system, the Holmes used moving air to help control engine temperature. The car was powered by an air-cooled overhead valve inline six-cylinder engine.
The man behind the car was Arthur Holmes, a Canton, Ohio native who spent his early career at the Franklin Automobile Company in Syracuse, New York. Franklin had been developed with the assistance of engineer John Wilkinson beginning in 1902. Over the next several decades, Franklin became America’s most successful air-cooled automobile.
Holmes served as vice president and sales director at Franklin and understood the logic behind air-cooled design. Air cooling eliminated the need for a radiator, water pump and coolant system. It also avoided freezing problems in cold weather, an important advantage at a time when antifreeze was not yet widely used.
Holmes believed in a more traditional Franklin course while the company was moving in another direction. Rather than stay, he returned to Canton and set out to build a car under his own name.
The Birth of the Holmes Automobile Company
The Holmes Automobile Company was founded in Canton, Ohio in 1918. With local backing and Arthur Holmes at the center of its engineering vision, the company entered the crowded post-World War I automobile market with a bold idea.
Holmes would build a full-sized air-cooled car.
Holmes wanted to prove that air-cooled engineering could work in a larger, more refined automobile. The car used an air-cooled inline six-cylinder engine, a flexible chassis and full-elliptical leaf springs. It was designed to give passengers a smooth ride while avoiding the complexity of a water-cooled system.
The company had ambitious plans. Holmes hoped to build thousands of cars a year, but the reality was much harder. The automobile market of the early 1920s was unforgiving, especially for small independent manufacturers. Competition was fierce, materials were expensive and buyers spending luxury-car money often preferred established names with stronger dealer networks.
The Holmes was expensive, and the company also faced public scandal. In 1921, an arrest warrant was reportedly issued for the company’s vice president on charges of larceny and embezzlement. Plans to reorganize followed, but they did not save the company.
The Series 4: Air-Cooled Luxury
The 1922 Holmes Series 4 Limousine represents the company’s most mature idea of what a full-sized air-cooled luxury automobile could be.
The car is powered by a 246-cubic-inch air-cooled overhead valve inline six-cylinder engine with a single Stromberg carburetor. It produced about 32 horsepower and used a three-speed manual transmission. The chassis used live axles with full-elliptical leaf springs and rear-wheel mechanical drum brakes.
The cooling system is one of the most fascinating parts of the car. Instead of using a radiator, coolant and water pump, the Holmes relied on air. A fan behind the grille helped move air around the engine, while the hood sides helped contain and direct that airflow. The car’s open grille and low, tapered hood made little attempt to imitate the look of a conventional water-cooled automobile.
It is a formal limousine, finished in bright blue with black fenders and roof, grey cloth upholstery and red wood-spoke wheels. The passenger compartment reflects the expectations of luxury travel in the early 1920s. It includes two rear jump seats, pull-down shades for privacy, a glass division and a Perfection heater. A net beneath the tall roof provided storage for hats, a small but wonderful reminder of the world this car was built for.
Today, the Holmes Series 4 Limousine stands as a rare survivor from one of America’s most unusual independent automobile companies. It did not make air cooling famous. Franklin had already done that. But Holmes tried to prove that air-cooled engineering could belong in a larger, more formal luxury automobile. That ambition is what makes this car so fascinating more than a century later.
