There is another aspect to the story of the patent of the wire cartridge.
Hall and Frederick Joyce of London, England, disputed the ownership of the so-called “patented wire cartridge” by Eley and proceeded to market their own improved wire cartridges, stating that “the wire cartridge was based on the principles of Robert George Jenour, the real patentee who still possessed the patent when he died.” Joyce stated that the patent expired. Certainly Eley disputed this but I have seen no records of a court case to settle the argument, but there may be some.
This appeared with the Joyce Wire Cartridge advertising. The Joyce wire cartridge seem to have been short lived, few examples have survived as compared to the Eley wire cartridges which continued production for more than eighty years.
It is interesting to note that the first year’s failure of the Eley wire cartridge due to balling was solved when bone meal was used within the shot load. Perhaps I have licked my fingers too often in handling or repairing broken Eley wire cartridges but the filler sure tastes very salty and appears to be a very fine sand. I hope the lead oxide has not affected my thoughts. Even today the filler seems to change occasionally for new shot shell loads.The latest is a semi-solid still with the purpose to hold shot together for some distance and break apart with good pattern. Amazing to me that almost two hundred years later shot shell makers are still in the discovery mode with new design of shot cups and the filler within the shot.
