A scarce 19th century coffin-maker's parallel rule designed specifically for measuring the placement of handles on coffins. This rule was designed and patented by Pawtucket, Rhode Island funeral director Dexter W. Bellows in 1896. His name is stamped within the wood, and the brass hinge is stamped "PATENT APPLIED FOR." These rules were sold by the National Casket Company of Baltimore. An example can be found in the Smithsonian's collection.
