Pacific Amusement Manufacturing, Rock-Ola, and Exhibit Supply, he went into business with Lyndon Durant in 1942 under the name United Manufacturing. After a break with Durant, Williams founded the Williams Manufacturing Company in 1943 at 161 West Huron Street in Chicago, Illinois. The first seven products were a fortune-telling machine called Selector Scope (1944), two electro-mechanical (EM) games, Periscope (1944) and Liberator (1944), a novelty called Zingo (1944), a pinball conversion called Flat-Top (1945), another EM arcade game, Circus Romance (1945) and a second pinball conversion called Laura (1945). The two pinball conversions (Flat-Top & Laura) were built by purchasing older pinball machines made by other companies and changing artwork and other elements on the playfield. The lack of raw materials during World War II made the manufacture of new machines difficult and expensive. The first all original amusement device made by Williams was a flipperless pinball machine called Suspense (1946). During the late 1940s and early 1950s, Williams continued to make pinball machines and the occasional bat-and-ball game. In 1950, Williams produced Lucky Inning, their first pinball machine to have its bottom flippers facing inward in the modern manner. In 1948, Williams sold 49% of his company to a Philadelphia distributor named Sam Stern, who became a vice president and took over much of the day-to-day running of the company. In 1959, Stern orchestrated a buyout of Williams by Consolidated Sun Ray, a New York retail conglomerate that operated drug stores and discount houses, which renamed the company the Williams Electronic Manufacturing Corporation. Harry Williams left after the buyout, though did occasional work for the company. The last game he designed for Williams was also one of the last electromechanical games, Rancho (1977). In 1961, Stern bought Williams back from Consolidated Sun Ray. Three years later, the company was acquired by the Seeburg Corporation, which also purchased United Manufacturing. The two amusement companies were consolidated under the Williams name, but moved into the United factory. Sam Stern continued to run the amusement business, which was renamed Williams Electronics in 1967. In 1962, 3 Coin became the best selling Williams machine with 1,100 units sold. One year later, Skill Pool sold 2,250 units. In 1964 Williams was purchased by the Seeburg Corporation. Its 1966 pinball machine A-Go-Go, with its avant-garde 60s theme, sold a record 5,100 units. Early Williams pinball machines often included innovative features and pinball firsts, such as
