Title: Bottom valve tripping and liquid channeling device for an automated bailer of shallow wells

Patent ·
OSTI ID:6424282

A cylindrical body defines a through passage for a pipe bailer and its contents, and has a side exit for the contents. A circular concave element is fixed adjacent to 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 upward to close the through passage and simultaneously engage a stinger to trip a bottom valve in the bailer. This releases the contents on and into the circular concave element for channeling to and out of the side exit, and 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. 1 claim.
