Abstract

681,465. Cleaning pipes &c. BAKER OIL TOOLS, Inc. Dec. 19, 1950. No. 30954/50. Class 99 (ii). A body 10 attachable to a drill string C in a well casing B has at least one circumferentially-continuous groove 20 in which are located circumferentially - spaced scraper blades 18, which may have helical teeth 19 urged outwardly, e.g. by springs 40, to an extent limited by retainer members 25 between the blades and also positioned in the groove. Members 46, 47 may engage in grooves at the ends of the blades to provide driving connections when the body is rotated. There may be sets of longitudinally-spaced blades which are angularly displaced with respect to each other, and a body passage 11 for the circulation of a flushing fluid.
