This well-known bicycle and typewriter firm had already built components for Benz as well as a few De Dion tricycles when their first car appeared in 1900. This closely resembled the contemporary Renault, with tubular frame, shaft drive, and front-mounted 400cc single-cylinder De Dion engine; suspension was full-elliptic all round and steering was by tiller, but both these archaisms had gone by 1901 when a bigger 510cc power unit was standardized. By 1902 the company were making their own engines, an 850cc single and a 1.7-litre twin, there were four forward speeds, and the lateral radiators continued the Renault idiom.

With the arrival of Edmund Rumpler in 1903 the Adler idiom crystallized, even if this experimental swing-axle suspension did not pass beyond the prototype stage. Characteristics of the new models were side valves in an L-head, dual ignition, pressed-steel frames, and rectangular radiators. Four cylinders were preferred, though singles were still offered in 1905, and twins as late as 1909. By 1905 there were 4-cylinder cars of 2.8-litres, 4-litres and 7.4-litres, this last figuring in Adler’s Herkomer Trophy entry, and attracting an order from Kaiser Wilhelm II in 1907. If the 1906 Kleinwagen, a 1.032cc aiv V-twin with water cooling and steel artillery wheels, marked a retrograde step, by 1907 the company had adopted the unit gearbox, and were experimenting with ioe engines, achieving a 3rd place in the Prince Henry trials. There were also some modest short-stroke fours. A 2-litre 8/15ps was followed a year later by the successful 1.555cc 7/15. This developed into the 1.8-litre 7/15, popular in England as the 12hp. These small Adlers had dual ignition, but foot accelerators were found only on the bigger cars as late as 1913. There was a fast 5.2-litre 76bhp ioe model for the 1910 Prince Henry Trials, and a smaller 3.2-litre version was offered to the public. It evolved into the 15/40 of 1913, with 3.8-litre and 69bhp, used as the basis for Adler’s unsuccessful 1914 T.T. racers. Their Knight-engined 1911 cars did not progress beyond the prototype stage, but very attractive was that year’s new model, the 1.3-litre K voiturette, initially with pair-cast cylinders, but offered in 1913 with Monobloc engine and a choice of side-by-side or tandem seats. Rear suspension was full-elliptic. It did 50mhp and 38mpg, and was well received by Britons, who bought it under the name of Morgan-Adler Carette. There were also some large sv fours, the 4.8-litre 19/45 appearing in 1911, followed in 1912 by a 7.8-litre 30/70, and in 1914 by a V-radiatored 9.1-litre monster, top of a nine-model range. Also new was an enlarged K, the 1.552cc KL with four-seater bodywork and semi-elliptic rear springs.

A selection of the more popular 1914 types reappeared in 1919, and even in 1922 a replacement for the KL, the 6/22PS, retained a fixed head and reverted to a separate gearbox. Adler’s first sixes came in 1925, these boasting alloy pistons, detachable heads, and front wheel brakes. The 10/50 had a 2.6-litre Monobloc engine, but the 4.7-litre 18/80 was of biblock type. Also new was an essay in the American idiom, Becker’s 1.550cc 4-cylinder Favorit. Three years later it had been joined by a 2.9-litre six and a 3.9-litre straight-8, both with hydraulic brakes, these being offered on an enlarged and modernized Favorit in 1929. 

At the Geneva Show in 1932 Adler presented their new 1.5-litre Trumpf with front-wheel drive and independent wheel suspension, a design of H.G. Röhr. This first front-driven car was followed by the 1-litre Trumpf Junior, the 1.7-litre Trumpf and the 2-litre model. The competition versions of these models – very often fitted with aerodynamic bodies – were very successful in the years from their appearance to the outbreak of World War 2. Streamlined Trumpf and Trumpf Junior cars gained 22 international records in 1935 and 1936 on the Avus and the Darmstadt Autobahn. A win in the Leinster Trophy Race of 1934, a Team Prize at Spa in 1936 in the 2-litre class, a 2-litre class win and 6th place overall at Le Mans in 1937 were only a few of the victories. In 1937 Adler introduced a rear-wheel driven model again, the 2.5-litre with 6-cylinder 50bhp engine, aerodynamic body and swing axles. The sports version of this type developed 80bhp.

Production of private ceased in 1939. Some prototypes of the Trumpf Junior were produced after the war and were on show at the Hanover Fair 1948, but production was not taken up. Instead of this, production of motorcycles was resumed, lasting until 1957.

Chalmers / Chalmers-Detroit

US, 1908 – 1924

Chalmers Motor Car Co, Detroit, Mich.

The Chalmers was one of the most popular automobiles made in the United States for more than a decade. The Chalmers was the successor to the Thomas-Detroit which was built by a company which had been founded in 1906 by E.R. Thomas (builder of the Thomas car in Buffalo, N.Y.), Roy D. Chapin and Howard Earle Coffin; the two latter had previously served at Oldsmobile. The Thomas-Detroit of which some 500 were sold during the first year of production, was marketed through the parent firm in Buffalo which manufactured a larger line of cars under the Thomas emblem. The Thomas-Detroit was a medium priced four-cylinder car which had been designed by Coffin. In 1907, Hugh Chalmers, vice president of the National Cash Register Co and a noted salesman, entered the firm. Shortly after, he bought a half of E.R. Thomas’ stock and became president of the company which became the Chalmers-Detroit Motor Company. The Thomas-Detroit became the Chalmers-Detroit in 1908 and in 1910, the Chalmers. Open and closed Chalmers models in two lines comprised the Chalmers four-cylinder cars, with self-starters appearing in 1912. Chalmers (as Chalmers-Detroit) had distinguished itself in road races as early as 1908 when W.R. Burns won the Motor Parkway Sweekstakes at Jericho, N.Y., averaging 48.7mph in the six-lap 140.76 mile run.

In 1913, the Chalmers brought out its first 6-cylinder model, as well as the four and apart from small mechanical and design changes, continued both until 1914. The Chalmers four was dropped from the 1915 line, however, and sixes were to be used exclusively in Chalmers until the ending of manufacture. By 1915, some 20.000 Chalmers cars per year were coming off the Chalmers production line and would even exceed that figure before the advent of World War 1. In 1917, an L-head motor replaced the earlier overhead-valve type and on August 4th, Chalmers again headed racing news when Joe Dawson won the 24-hour stock Car Endurance Run at Sheepshead Bay, N.Y. Sales flagged following the end of the war and Hugh Chalmers, always the salesman, and with the realization that a competitor, Maxwell, wasn’t faring well either, arranged to lease his Chalmers plants to Maxwell, using his salesmanship to promote the two concerns and getting the benefit of Maxwell tooling and manufacturing equipment. By the early 1920s, however, many makes of cars were in financial difficulties due to over-expansion and recession, and Walter P. Chrysler was called in to try and reorganize Maxwell. Chrysler was at this time planning his own corporation and in 1922 Chalmers was taken over by Maxwell which had become a Chrysler subsidiary. The last Chalmer cars for sale were equipped with Lockheed hydraulic brakes but 1923 was the last year of Chalmers production with some 9000 units leaving the factories. The Maxwell survived until 1925 when it became the Chrysler Four.
