Today in 1898, US Patent 616696 A was issued, an invention of John R. Cochran, for his “Hose Cleaner.” There’s no Abstract, although in the description it includes these claims:

My invention relates to methods of cleaning and cleaners for the interior of hose or pipe, and more especially such hose or pipes as are used by brewers in racking off beer. During the process of racking off beer the hose or pipes used as conveyers become fouled or dirty in the interior and it becomes necessary to clean the hose or pipe. Inasmuch as the dirt or foreign matter generally adheres firmly to the wall of the hose or pipe, it is not an easy matter to dissolve, loosen, or discharge it. By the use of my method and devices the dirt collected in the tubes is thoroughly loosened or dissolved and carried off or discharged, leaving the interior of the tubing or hose clean and sweet.
