Interestingly this machine is labelled "Watkin's"... (suggesting the name was Watkin), whereas other examples have had "Watkins'" labels (ie. suggesting the name is Watkins). Both can't be right! It's probably a fair assumption the patent is correct (showing the latter spelling) and this one is wrong.
