Even through challenging times, the Lister family remained deeply committed to innovation, always looking for ways to adapt and thrive in changing markets. The late 1930s were particularly difficult, with the world on the brink of war and economic uncertainty looming large. Yet, instead of retreating, the Listers saw an opportunity to leverage their in-house expertise in metalwork to create solutions that would drive the business forward.
In 1939, the company filed a patent for an improved dust extraction system designed specifically for grinding and polishing equipment that were essential for a variety of industrial applications. Dust and debris generated during these processes were a significant problem, often leading to machinery malfunctions and health hazards for workers. Recognising this gap in the market, the Listers focused their engineering skills on refining the existing technology to create a more efficient and effective dust extractor.
Their innovation didn’t just improve the safety and efficiency of industrial operations in the UK; it also opened new avenues for global trade. Manufacturing began at their Tipton-based sheet metal factory, and before long, the improved dust extractors were being exported to the United States, where industrial demand was high. This not only diversified their revenue streams but also established James Lister & Sons as a forward-thinking, internationally recognised brand.
