HOOVER, John - patent
Source: Crawfordsville Star June 28, 1877 p 5
John Hoover, the old tinner and coopersmith has at last been granted a patent on his superb Water Filterer for cisterns. It is thought by those who have tested it to be one of the indespsibles for purifying water. It will be sold at poor man’s figures. Call at Greggs and use it.
