Patent number: 4369095Abstract: The apparatus comprises a driven rotatable shaft carrying at its working end rotary scraper means and a tapered centering device in advance of the scraper means which is freely rotatable with respect thereto. The shaft end carrying the scraper means and the centering device is connected to the driven portion of the shaft by a universal joint. The scraper means are connected to the shaft behind the universal joint by several circumferentially spaced spring-loading means which normally keep the scraper means and centering device normal to the shaft but which permit those means to tilt relative to the shaft if the latter is angularly misaligned with a clean-out opening. Thus, the scraper tools are always in contact with a flat cover seat. The centering means have outwardly extending stops which make contact with the cover seat and limit the penetration of the centering means into the ascension pipe opening.Type: GrantFiled: April 29, 1981Date of Patent: January 18, 1983Assignee: Wilputte CorporationInventors: Rajagopala Venkataramani, Raymond Levonaitis
