Abstract

1830. Crockatt, W. Jan. 23. Tube-extractors. -A tube extractor is provided with a mandrel a screw-threaded for a part of its length and tapering to a larger diameter at one end, a number of dogs or segments i slidably mounted on the tapered portion of the mandrel and held together by a spring band or bracelet k in grooves in the segments, and a distance-piece f adapted to engage the tube-plate and to be engaged by a nut d on the screwed mandrel to effect the withdrawal of the tube. A nut e may be provided on the screwed mandrel below the distance-pieces to co-operate with a spring l, a sleeve, or equivalent for effecting an initial grip between the dogs and the tube.
