Several bellfoundries in Cincinnati, including two of the largest and longest-lived in the USA, made either bronze or iron bells. One of those, the Buckeye Bell Foundry (operated by Vanduzen), was among the four minor American makers of chimes; the data side of this Website has a list of Vanduzen chimes, including a brief sketch of the history of this foundry.
The largest of many American producers of iron or steel bells was probably the C.S.Bell Company, located in the town of Hillsboro, east of Cincinnati. Using a special cast steel alloy called “crystal metal,” this firm produced bells of all sizes from 12″ diameter postmount farm or dinner bells to 48″ diameter church bells. These bells, unlike those made of bronze, do not carry any inscription (except possibly a size number on the top). Instead, the identification of the maker is found on the yoke from which the bell hangs.
