Abstract

1,065,667. Advancing mine roof supports. STAMICARBON N.V. June 18, 1964 [June 20, 1963], No. 25322/64. Heading E1E. Mine roof support frames 1, 1', each comprising props 2, 3 are connected to respective advancing cylinders 8, Fig. 4 (not shown), slidable side-by-side in rectangular passageways (7) in a movable guide 6. Springs 9, 10 allow relative movement over uneven ground. The piston 13 shown has a rod 14 which extends through both ends of the cylinder and is connected to the guide 6 at 15, 16. The second piston (not shown in Fig. 1) is similarly connected. Alternatively the guide 6 may be connected to a piston rod or cylinder by stops. During advance, pressure is admitted to the first cylinder 8 to move it along the guide 6 and then to the second cylinder 8 to move the guide 6 itself. The ends of the cylinders 8 ar formed as or provided with ploughs 19 to clear debris from the guide 6. Reference has been directed by the Comptroller to Specification 850,170.
