Jennings Chief Slot Machines

Ode D.Jennings Company

1874-1953 Logo

Ode Jennings was born in Kentucky in 1874. In his late 20's he went to work for the Mills Novelty Co where his natural engineering ability soon made him an expert on coin-operated machines. So much so he was given the task of running the Mills Spectatorium at the 1904 World Fair in St Louis . This was a massive building, partly designed by Thomas Edison , and featured (what was said at the time to be ) hundreds of Mills slot machines, it was the only free attraction at the worlds fair but probably made more money than any other. The building was brightly lit at night (Edison's contribution) and attracted a huge number of visitors.

Two years later in 1906 he left Mills(seemingly on good terms) and founded the Industry Novelty Co Inc whose business was refurbishing Mills machines.

By 1923 the company was called O.D.Jennings & Co and was doing very well despite a misguided attempt to revive the Garbell Typewriter Corp which he had bought out of liquidation, the attempt was a total disaster. In the same year, he was granted a US patent for an improved coin selecting device which could discard coins that were too small. In 1925 he invented and was granted a patent for an anti coin jamming device

In 1925 Ode bought a large house/farm in Schaumburg Illinois and like another country boy turned factory owner, Henry Ford, spent the rest of his life escaping from the factory whenever possible to be a part-time gentleman farmer breeding cattle and horses

By 1936 the company, was, like Mills, making a large range of slot machines in different styles, including a very unusual payout pin table called the Sportsman. This was more like a slot machine that a pin table

Ode Jennings died on 29th November 1953 at the age of 79 having personally run the company for 47 years. Having no children he left everything in trust to his wife on the proviso that it passed to the town and hospital on her death but she seems to have got round that as far as the company was concerned by setting up Jennings and Co in 1954 which purchased the assets of O.D.Jennings and Co from the estate of Ode Jennings.

Jennings and Co were merged with theHershey Manufacturing Co in 1957 although 80% of Hershey's production was Jennings machines. By the early '60s Jennings was the top producer of slot machines in the US with 45% of total sales.

By the mid '60s with laws in the US cutting slot sales to a fraction American Machine and Science Co acquired the failing Jennings Co along with Bell-o-matic (the remains of the Mills Slot division) and merged them to become TJM Corp run by Tony and John Mills but a failure to come to grips with the new electromechanical slot machines Bally had grabbed the market with plus the failure of Mills to protect their business rights in Japan caused the company to close in the 1980s

Ode Jennings wife Jeannette died in 1963 and, as proposed in Ode's will, left the house and lands to the town and donated $500,000 to the local hospital for the building of the O.D.Jennings wing which opened in 1966.

In 1948/9 Jennings looked to produce the first of a range of machines that were

to become their most iconic and recognisable machines, Based on the

slightly earlier, more rounded design these had straighter crisper lines and

although many different variations followed they all retained the same basic look and shape.

The first was the 'solid front'

in production in 1980

These 400's were found packed like this 30 years after they were made, they appear to have been well used before storage

(this photo and that of some of the 400/700* series courtesy of the owner of the machines John Spina)

The 400 /700 series was a valid attempt at a circuit board controlled hopper payout machine to meet the new market dominated by Bally but was unreliable and too late on the scene and marks the end of the line for Jennings named machines
