Inventors:
David L. Barton - Avondale Estates GA
Patrick Scott Kelly - Covington GA
Patrick Scott Kelly - Covington GA
International Classification:
E02D 2914
US Classification:
404 25
Abstract:
An entrance-deterring cap for manhole openings in which an annular pan has an annular flange extending laterally from a skirt for supporting the pan on an upper edge of a frame in a manhole opening. A support member comprises an elongate bar disposed outwardly of the pan with a pair of plates rigidly attached at distal ends of the bar. A threaded stud is attached to the elongate bar for insertion through an opening in the bottom of the pan whereby the plates of the bar are exposed outwardly of the skirt with the distal ends of the plates near the flange of the pan. An elongate flexible strand attached to the threaded stud extends through an opening in the pan for coupling the bar with the pan. The pan is supported by the flange on an upper surface of the frame in a manhole opening and the elongate bar is suspended by the flexible strand below the pan in a throat of the manhole opening. The strand is pulled in order to move the threaded stud through the opening in the pan.

US Patent:
5951200, Sep 14, 1999
Filed:
Feb 19, 1998
Appl. No.:
9/026161
Inventors:
David L. Barton - Avondale Estates GA
Assignee:
Barton Southern Company, Inc. - Conyers GA
International Classification:
E02D 2914
US Classification:
404 25
Abstract:
A cap formed with a pan that defines a central dish which receives a portion of the securing members that secure the pan to a manhole opening. A cover closes over the central dish to restrict entry of water and dirt contaminants into the central dish. The cover and the central dish thereby define an enclosure for the securing members which connect the cap to the manhole cover.
