The Stanley Motor Carriage Company was an American manufacturer of steam cars; it operated from 1902 to 1924. The cars made by the company were colloquially called Stanley Steamers, although several different models were produced.
|Founded||1902 (first vehicle produced 1897)|
|Fate||Sold and dissolved|
|Headquarters||Maple Street in Watertown, MA, United States|
|Francis Edgar Stanley and Freelan O. Stanley|
Twins Francis E. Stanley (1849–1918) and Freelan O. Stanley (1849–1940) founded the company, after selling their photographic dry plate business to Eastman Kodak. They made their first car in 1897. During 1898 and 1899, they produced and sold over 200 cars, more than any other U.S. maker. In 1899, Freelan and his wife Flora drove one of their cars to the top of Mount Washington in New Hampshire, the highest peak in the northeastern United States. The ascent took more than two hours and was notable as being the first time a car had climbed the 7.6 miles (12.2 km) long Mount Washington Carriage Road; the descent was accomplished by putting the engine in low gear and braking extensively. The Stanleys later sold the rights to this early design to Locomobile, and in 1902 they formed their own Stanley Motor Carriage Company.
Specifications and designEdit
Early Stanley cars had light wooden bodies mounted on tubular steel frames with full-elliptic springs. Steam was generated in a vertical fire-tube boiler, mounted beneath the seat, with a vaporizing gasoline (later, kerosene) burner underneath. The boiler was reinforced by several layers of piano wire wound around it, which gave it a strong but relatively light-weight shell. In early models, the vertical fire-tubes were made of copper, and were expanded into holes in the upper and lower crown sheets. In later models, the installation of a condenser caused oil-fouling in the expansion joints, and welded steel fire-tubes had to be used. The boilers were reasonably safe since they were fitted with safety valves. Even if these failed, any dangerous over pressure would rupture one of the joints long before the boiler shell itself could burst. The resulting leakage would relieve the boiler pressure and douse the burner with very little risk to the passenger. There is not a single documented incident of a Stanley boiler exploding.
The engine had two double-acting cylinders, side-by-side and equipped with slide-valves, and it was a simple-expansion type. Drive was transmitted directly by the crankshaft to a rear-mounted differential using a chain. Owners often modified their Locomobiles by adding third-party accessories, including improved lubricators, condensers, and devices which eased the laborious starting procedure.
To overcome patent difficulties with the design they had sold to Locomobile, the Stanley brothers developed a new model with twin-cylinder engines geared directly to the rear axle. Later models had aluminium coachwork that resembled the internal combustion cars of the time, but they retained steam-car features by having no transmission, clutch, or driveshaft. They also had a fully sprung tubular steel frame.
When they later moved the steam boiler to the front of the vehicle, the owners dubbed it the "coffin nose." The compact engine ran at considerable steam pressure, with the 10-horsepower (7.5 kW) boiler described in 1912 as having the safety valve set at 650 pounds per square inch (4.5 MPa), with the burner set to automatically cut back when pressure reached 500 pounds per square inch (3.4 MPa). The twin-cylinder steam engines were at that time 10 horsepower, with 3+1⁄4-inch (83 mm) bore and 4+1⁄4-inch (108 mm) stroke, and 20 horsepower (15 kW) with 4-inch (102 mm) bore and 5-inch (127 mm) stroke, and made extensive use of ball bearings. In order to improve range, condensers were added from 1915.
A Stanley Steamer set the world record for the fastest mile in an automobile (28.2 seconds) in 1906. This record (127 mph or 204 km/h) was not broken by any automobile until 1911, although Glen Curtiss beat the record in 1907 with a V-8-powered motorcycle at 136 mph (219 km/h). The record for steam-powered automobiles was not broken until 2009.
Production rose to 500 cars in 1917.
During the mid to late 1910s, the fuel efficiency and power delivery of internal combustion engines improved dramatically and using an electric starter instead of the crank, which had been notorious for injuring its operators, led to the rise of the gasoline-powered automobile, which also was much cheaper. The Stanley company produced a series of advertising campaigns trying to recover the car-buying public away from the "internal explosion engine," but it was unsuccessful. Their advertising slogan was, "Power – Correctly Generated, Correctly Controlled, Correctly Applied to the Rear Axle." These were early examples of the fear, uncertainty and doubt advertising campaign, since their aim was not to convince buyers of the advantages of the Stanley Steamer but to suggest that internal combustion automobiles could explode.
Sale and closureEdit
Francis died in 1918 when he steered his car off the road into a woodpile while attempting to avoid farm wagons travelling side by side. After his death, Freelan sold his interests to Prescott Warren. The company suffered a period of decline and technological stagnation. Production specifications show that no model with a power output of more than 20 hp (15 kW) was produced after 1918. Better cars were now available at much lower cost. For example, a 1924 Stanley 740D sedan cost $3,950, compared with less than $500 for a Ford Model T. The widespread use of electric starters in internal combustion cars, beginning in 1912, eroded the remaining technological advantages of the steam car.
The smaller scale of merchandising, a lack of effective advertising, and the general desire of motorists for higher speeds and faster starting than offered by Stanley vehicles were the primary causes of the company's demise. The factory closed permanently in 1924.
In popular cultureEdit
An entire song titled "The Stanley Steamer" appears in the 1948 film Summer Holiday starring Mickey Rooney and Gloria DeHaven. The number, written by Harry Warren with lyrics by Ralph Blane, features an extended musical sequence with what appears to be a fairly early yellow 10 HP model.
Bugs Bunny mentions a Stanley steamer in the cartoon short Robot Rabbit, released in 1953.
A Stanley Steamer appears in the 2003 film Seabiscuit.
Stanley from Cars and Cars 2 who appeared in Time Travel Mater is a Stanley Steamer. He was the husband of Lizzie. There is a statue of him that is seen in front of the fire station in Radiator Springs where Red lives. He was the town's founder.

That was the day that F. O. Stanley and his wife, Flora, decided it would be good publicity for their steam-powered Stanley Locomobile if it were the first car to be driven up the 7.6-mile Mount Washington Carriage Road.
