Now built under license from Pitcher Drilling Company, Inc. by Acker Drill Co., Inc. recovers accurate samples from soft rock, friable shales The Pitcher Sampler is designed specifically to recover accurate samples from formations that are too hard for thin-wall shelby samplers or too brittle, soft or water-sensitive to permit satisfactory recovery by conventional core barrel type samplers. Several years of successful application in virtually every type of "problem" formation prove that PITCHER SAMPLER saves time, saves money...insures exceptional accuracy. If you're now using a core barrel type sampling tool, compare it with these exclusive features offered by the PITCHER SAMPLER... Heavy-duty, triple ball-bearing hang- er is sealed 4-ways against drilling fluid to prevent freeze-ups and in- sure long, trouble free service. No more crumpled shelby tube; no presetting, no surface control need- ed. Spring-seated tube telescopes into cutter barrel as formation hard- ness increased. Sliding valve directs drilling fluid through shelby tube to hole bottom for thorough flushing action, then automatically diverts fluid from tube when tube contacts bottom. Hole remains full gage...no reaming Drilling fluid can't undercut shelby tube and erode or contaminate sam- ple even in softest materials. Samples dry or saturated material with equal speed, ease and accuracy. No core lifter is needed to protect or retain sample. Sample all materials- including soft rock -from top to bottom of hole. Shelby tubes can be changed in less Drill can be stopped, rod re-chucked (even raised slightly) without break- ...a tool that relieves you from the limitations of core barrel type samplers □ RILL COMPANY E-Mail: sales@ackerdrill.com Website: www.ackerdrill.com
