Abstract

296,352. Schroeder, A. C. Aug. 29, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Drills.-The clearing passages 15 in a well-drilling tool are. closed for lowering into the hole by plugs 10 of soft metal such as lead joined together by an easily breakable connector such as aluminium wires 18 twisted together. The pressure of the clearing fluid breaks the connector and releases all the plugs. The plugs may be solid, or hollow as shown.
