Abstract

5303. Nederlandsche Maatschappij tot het verrichten van Mijnbouwkundige Werken. March 6, 1913, [Convention date]. Bore-hole apparatus.-A catch device for boring- rods comprises a clamp, made of halves 1, 2 pivoted together and rigidly locked by a bolt 4, and carrying steel catching elements 5, 6, which may be opened by bent spindles 7, 8 and bear on parts 9, 10, 11, 12 so as to relieve these spindles from pressure. On raising the boring-rods, the couplings thereon open the catching-elements, which close when the coupling has passed. If the cable breaks while lifting or lowering the rods, the catching- elements 5, 6 engage the rod couplings to prevent the rods from falling. The catch device closes the mouth of the bore-hole during boring.
