Abstract

1,013,529. Boring earth &c. SABZGITTER MASCHINEN A.G. Nov. 9, 1964 [Nov. 30, 1963], No. 45673/64. Heading E1F. Boring apparatus having cutting edges 6 and comprising a container for the spoil is formed by parts A, B pivotal about an axle 24. The container is moved vertically by cable and rods, the rods passing through a rotary table. During boring the parts are held together by latches 10. When the container is raised so that rollers 17 on levers 16 engage the underside 18 of the table the latches are released, and when the container is raised further rollers 9 on levers 7, 8 cause the parts to pivot to the position shown dotted for discharge of the spoil.
