In the mid-1880s, a factory owner purchased pneumatic molding machines (for $500,000) that produced inferior casings at a higher cost than the earlier process, in order to displace the skilled workers (who were also union organizers). The machines were abandoned after 3 years. pic.twitter.com/T1xOaPNfZm
