The McCracken sewer pipe machineis designed to make bell end sewerpipe from 4 to 24 inches in diameterand 24 and 30 inches long. The ma-chine packs the material into the pipevery hard and dense and even morein the bell. The bell is of standardshape, length and thickness. The in-ner surface of pipe and bell is trowel-ed so as to be absolutely DIAGRAM OP ATLAS specifications, to resist an internalpressure of 15 pounds without perco-lation and SO pounds without ilkistrations show two views ofthe machine and also a picture of con- .VilUOTI-; PIPE The machine also makes chain tile 4to 24 inches in diameter and 12, 18, 24and 30 inches long.
