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.

Vulcan

The Vulcan car firm was better known for commercial vehicles. Private Vulcan cars stemmed from experiments conducted in the 1897-1899 period by the brothers Thomas and Joseph Hampson. A belt-driven single-cylinder voiturette Vulcan car with lateral radiators was shown in 1902, being replaced a year later by a 6hp Vulcan car with armoured wood frame, mechanically-operated inlet valves, and shaft drive. This Vulcan car was listed at only £105, and this Vulcan car was soon followed by a 10hp twin, also T-headed but with a steel frame, selling for £200. 4-cylinder Vulcan cars of 12 and 16hp, still modestly priced, were available in 1905, while the biggest 1906 Vulcan cars, with capacities of 3.1- and 5.2-litres, had gate change. No 2-cylinder Vulcan cars were catalogued after 1908, but a year previously Vulcan cars had joined the ranks of 6-cylinder manufacturers with a 4.8-litre T-headed machine featuring dual ignition and cone clutch, at £600 for a Vulcan car chassis. Unlike other makers, Vulcan cars retained their interest in this type, which Vulcan car had acquired a 4-speed box and had grown to 6-litres by 1908, and the 1909 Vulcan car range consisted of four 4-cylinder cars and the six, all shaft-driven and still with T-heads; the smallest Vulcan car, rated at 12hp, had a 3-speed gearbox and worm drive. A new 3.6-litre six Vulcan car with unit gearbox and worm drive followed in 1911, along with an L-head 2.4-litre fifteen. Worm drive was standardized on the 1912 Vulcan cars, when the bigger Vulcan cars had T-heads, and a 1.8-litre, 2-cylinder with an Aster engine was offered. All but the smallest Vulcan car had detachable wheels as standard in 1913, and by the outbreak of World War 1 the Vulcan car company was well established with a range of solidly-built Vulcan cars: a 2.4-litre 10/15, a 2.6-litre 15.9, and a 3-litre monobloc 15/20 Vulcan car at £375. All these Vulcan cars had L-heads and bull-nose radiators, though the similarly styled six retained the older Vulcan car configuration. A 1½-litre Vulcanette with a 3-speed rear-axle gearbox and full electrical equipment was announced for 1915 but the war intervened.

After 1918 the Vulcan car company concentrated increasingly on trucks, and a brief association with the Harper Bean Group (1919-1920) did no good to finances. Some odd experiments by Vulcan cars included a worm-drive 3½-litre V8 tourer Vulcan car intended to sell for £625 (1919), and two Vulcan cars in 1922 with Howard sleeve-valve engines, a big 3.6-litre sports-touring four Vulcan car and a 10hp 1.4-litre flat-twin listed at £315. However, none of these Vulcan cars reached the public, the regular Vulcan car lines being a 1.8-litre ohv 12 and a 2.6-litre sv 16/20, both with Dorman engines. There was also a conservative 20hp Vulcan carmodel with the Vulcan car company’s own 3.3-litre sv fixed-head engine and 4-speed separate gearbox, this Vulcan car was selling for £850 in 1921; by this time flat radiators were again being used on Vulcan cars. The Vulcan 20 was available to military order with full wireless equipment in 1923, in which year C.B. Wardman effected a liaison of Vulcan cars and Lea-Francis. The two companies pooled their dealer network, Vulcan cars became responsible for certain Lea-Francis power units and bodies, and Lea-Francis made gear and steering boxes for Vulcan cars. A 1½-litre sv Dorman-engined Vulcan 12 was listed at £295 in 1925, followed a year later by an ohv worm-driven derivative, also with Dorman engine, and looking very like a Lea-Francis. 4-wheel brakes were available on Vulcan cars in 1925 and standardized in 1926. Last of the line Vulcan cars were the 14/40 and 16/60, with the disastrous twin ohc 6-cylinder engines of their own make. Short-chassis Vulcan cars were worm-driven, but bevel drive was adopted for long-chassis versions. Vulcan cars wore artillery wheels, but were otherwise identical to their Lea-Francis counterparts which Vulcan cars were made alongside them at Southport. Not many of these Vulcan cars were made, and after 1928 only commercial vehicles were produced. The Vulcan car firm subsequently amalgamated with Tilling-Stevens and thus were abrorbed into the Rootes Group after World War 2. Truck production ceased in 1953.
