above the middle wing was a tall clock tower with the "Singer" name clearly displayed for all to see for miles around. A total of of railway lines were laid throughout the factory to connect the different departments such as the boiler room, foundry, shipping and the lines to main railway stations. Sir Robert McAlpine was the building contractor and the factory was designed to be fire proof with water sprinklers, making it the most modern factory in Europe at that time. With nearly a million square feet of space and almost 7,000 employees, it was possible to produce on average 13,000 machines a week, making it the largest sewing machine factory in the world. The Clydebank factory was so productive that in 1905, the U.S. Singer Company set up and registered the Singer Manufacturing Company Ltd. in the United Kingdom. Demand continued to exceed production, so each building was extended upwards to 6 storeys high. A railway station with the company name was established in 1907 with connections to adjoining towns and central Glasgow to assist in transporting the workforce to the facility. Increased productivity came from 'scientific management' techniques which increased workloads whilst keeping salary overheads low, and in 1911, a mass walk out of 10,000 workers, the 'Singer Strike', took place in support of twelve women polishers, who had seen three staff dismissed, but the workload remained the same with no extra pay. It was significant in its recognition of the rights of women workers and 'collective bargaining' and predated the labour movement known as 'Red Clydeside'. A centenary film was made by the BBC about the female workers who stood up to the American management. In the First World War, sewing machine production gave way to munitions. The Singer Clydebank factory received over 5000 government contracts, and made 303 million artillery shells, shell components, fuses, and aeroplane parts, as well as grenades, rifle parts, and 361,000 horseshoes. Its labour force of 14,000 was about 70% female at war's end. From its opening in 1884 until 1943, the Kilbowie factory produced approximately 36,000,000 sewing machines. Singer was the world leader and sold more machines than all the other makers added together. In 1913, the factory shipped 1.3 million machines. The late 1950s and 1960s saw a period of significant change at the Clydebank factory. In 1958, Singer reduced production at their main American plant and transferred 40%
