Patent number: 11874077Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.Type: GrantFiled: October 3, 2022Date of Patent: January 16, 2024Assignee: STONEAGE, INC.Inventors: Travis Watkins, Jeffery R. Barnes, Daniel Szabo, Cody R. Montoya

Patent number: 10710127Abstract: A flexible cleaning lance safety apparatus is described as including a tripod support structure located close to an opening into an object to be cleaned. A flexible lance drive is fastened to the support structure for driving a high pressure fluid through a lance to the object to be cleaned. A snout tube is connected between the lance drive and an opening into the object to be cleaned. One or more micro pressure valves on each leg of the tripod support structure is operative to sense a predetermined force applied between the support structure and a support surface supporting the tripod support structure. When the predetermined force is sensed this causes the high pressure fluid to be diverted from the lance and the object to be cleaned to atmosphere.Type: GrantFiled: March 14, 2017Date of Patent: July 14, 2020Assignee: STONEAGE, INC.Inventors: Jeffery R.
