Abstract

727,971. Digging trenches. TWOSE (MANUFACTURING), Ltd., E. V., [formerly TWOSE, Ltd., E. V.]. ,July 31, 1952 [July 2, 1951], No. 15684/51. Class 6 (1). [Also in Group XXI] A trench-digging machine has a disc cutter 12 disposed between disc cutters 11 and 13 which make cuts that define the sides of the trench to be excavated. The disc cutters 11-13 are rotatably supported on bars 8-10 that are vertically adjustable in brackets 5 - 7 mounted on and secured in anv desired position along a bar 4 of the frame of the machine. The edge of the disc cutter 12 extends into the bifurcation of the nose portion of a plough 16 at the rear of the disc cutters. As the machine moves forward the disc cutters rotate, owing to the frictional resistance existing between them and the ground, to form cuts in the ground. The soil between the cuts is then completely freed by the plough 16 and discharged from the plough to the side of and clear of the trench by oppositely rotating turn-out discs 19, 20. The frames supporting the turn-out discs are pivotally connected to the frame of the machine and supported on skids.
