On August 8th, 1890 Peterson patented the Peterson "Dry System" pipe. This new design launched Peterson to worldwide pipe fame. The design features a reservoir that extends past the end of the tenon, which allows the smoke to condense and collect liquid in the pipe, and not the smoker's mouth. This system allows for a drier, cooler, more comfortable smoke. The pipes have an army mounted stem, which allows for easy disassembly and cleaning.
