Abstract

1522931 Boring earth &c P SCHMIDT 25 Jan 1977 [10 Feb 1976] 03000/77 Heading E1F A device for launching a percussion borer 1 at the start of a ground boring operation includes a trough 5 for supporting the borer 1 mounted on a base plate 2 which is anchored to the ground by pegs 4 and a braking roller 17 which permits forward movement of the borer 1 but prevents backward movement of the borer 1. The trough 5 is mounted on the base plate 2 by a universal joint 15 which allows the inclination and direction of the trough 5 to be adjusted.
