Abstract
224,187. Linnemann, A. June 21, 1924. Breaking-down appliances.-A device for breaking coal or rock from a seam &c. comprises a tube a provided with a nut b and adapted to be inserted in a bore-hole, when a screw c cooperating with the nut is caused to force forward a rod e having a wedge part which forces jaws g through slits in the tube and into the coal etc.; on further operation of the screw, owing to the abutment against the bottom of the bore-hole of a stop block f on the rod e, the tube is moved outwards from the bore-hole, the jaws g then tearing away the coal &c. A ball bearing may be provided between the screw c and rod e.
