Birmingham Iron Foundry

The Banbury mixer prospered through the 1920s, but not the Wanning family that owned the Birmingham Iron Foundry. In 1927, it was merged with Farrel Foundry and Machine to form Farrel Birmingham (later Farrel Inc.). They continued to manufacture the Banbury mixer [30]. 

A rather different approach was taken by Parrel Foundry and Machine, a competitor to the Birmingham Iron Foundry based in Ansonia, Connecticut. This mixing machine had a single rotor. It is described in patents by Bowen and Schnuck [27]. They sought to compete against the Birmingham Iron Foundry and marketed their machine as the Parrel Internal Masticator [2, 3]. 

In 1927 the Birmingham Iron Foundry merged with Parrel Foundry and Machine. This was caused by health problems of F. D. Wanning. The merged firm was called Farrel-Birmingham [19, 28]. The Parrel Internal Masticator was discontinued and the Banbury Mixer was emphasized.
