Maher ultimately uncovered some twenty-three metallic coffins.(2) On 11 April 1931, some of the caskets -- now removed to a collective burial site -- were photographed as part of the construction documentation (shown above).
Such metal caskets were popular during the second half of the nineteenth century, and a host of entrepreneurs patented their own versions. Almond D. Fisk of New York famously patented the model above in November 1848. It featured a round glass window for the face that was securely mounted to the casket. Fisk suggested removing all air from the coffin in order to prevent putrefaction.
Martin Crane -- representing Crane, Breed & Company of Cincinnati -- patented this "Metallic Coffin" in March 1855. His model featured an octagonal-shaped glass window for the face, and a name plate, both with ornamental molded surrounds.
In 1861, Knoxville inventor James H. Renshaw patented this "Metallic Coffin," asserting his improvements over earlier types. He employed unique bevels along the upper edges of his caskets.
Among the patent developers, one of the most unusual descriptions accompanied Philip K. Clover's "Coffin-Torpedoes," in which he claimed his invention would prohibit the "unauthorized resurrection of dead bodies" because any attempt to remove the body after burial would cause the death of the grave robber. His patent involved the use of spring-loaded explosives.
After the Civil War, Crane, Breed & Company established a New Orleans office on Magazine Street. They advertised their services in Gardner’s New Orleans Directory for 1867.Lucian Fay in 1864. These were a much simpler form, with Fay recommending the use of sheet rather than cast metal.
It's a good thing the 1931 State Capitol crew didn't encounter any of the booby-trapped torpedoes!
