When I started out in 1972, crackers were the name for generic bar stock hexes, as made by Ewbank and others such as Clog, etc. Chouinard hexes and then hexcentrics came later. I don't recall anything specifically named a "Crack Jack" or the like, but I would bet good money that I had heard about some sort of expanding tube chock in the '70s. (In particular before I visited the USA in 1978.)
