Abstract

1,038,952. Mine roof supports. W. E. & F. DOBSON. Nov. 8, 1962 [Nov. 21, 1961], No. 41545/61. Heading E1E. In a mine roof support consisting of at least one prop 1 provided with a floor or roof plate 2 the prop is arranged for tilting movement relative to the plate by a rubber or like resilient buffer ring 3 secured between relatively tiltable plates 2b, 4a as by bolts 5. The buffer ring may be clamped between intermediate plates disposed between the members 2b, 4a and in a further modification may be bonded to such intermediate plates, see Figs. 4 and 6 (not shown), respectively-such arrangements incorporating slightly modified clamping means as shown.
