ABSTRACT:
A cylindrical body defines a through passage for a pipe bailer and its contents, and a side exit for the contents. A circular concave element is fixed adjacent its perimeter to a shaft journaled in the cylinder body transverse the through passage and below the side exit, for swinging the circular concave element upwardly to close the through passage and simultaneously engage a "stinger" to trip a bottom valve in the bailer and thereby releasing the contents on and into the circular concave element for channeling to and out of the side exit, and for swinging the circular concave element downwardly to open the through passage for the travel of the pipe bailer up and down the shallow well. A crank is fixed to the shaft and actuated by a hydraulic cylinder controlled by limit switches responsive to bailer travel.
