Abstract

1,168,531. Shaft-boring machines. BERGWERKSVERBAND G.m.b.H. 5 Jan., 1967, No. 660/67. Addition to 1,100,934. Heading E1F. The machine described in Specification 1100934 for boring shafts in the earth is now so modified that the anchor means 12 for the carrier 13 rotatably supporting both the rotor 9 and the stator 8 of the motor of the boring means of the machine now extends ahead of the machine to engage with the walls of a pilot hole 4 instead of following the rest of the machine and engaging with the walls of the shaft formed on advance of the machine as disclosed in Specification 1100934.
