Abstract
1,079,172. Advancing mine roof supports. COAL INDUSTRY (PATENTS) Ltd. June 2, 1964 [March 8, 1963], No. 9327/63. Heading F1P. Remote control of a group of advanceable mine roof support units arranged in line and forming a first set 7, 9, 11.. 29 Fig. 1 each having a hydraulic ram 42 connecting it to the conveyer 40 and a second set of units 6, 8, 10.. 28 each connected to the conveyer by a mechanical link 41 is effected firstly by a solenoid valve B, Fig. 2 relay valve 63 and trip valve 90 whereby the main supply line 61 is connected through a pilot line 65 to the valve 66 controlling rams 42 for advancing units 7, 9 &c. either simultaneously or sequentially and secondly by a valve 77 which on a predetermined pull on link 41 releases units 6, 8 &c. to allow them to be advanced by forward movement of the conveyer 40. Valve 77 automatically closes when pull on link 41 ceases and units 6, 8 &c. are reset by pressure admitted from line 61 through valve 63, a line 64 and a non-return valve 75. Alternatively resetting is effected directly from line 61 through a manual valve 74. As shown each unit 6, 8 &c. comprises vertically telescopic props 71-73. The ram control valve 66 corresponds to valves 30 and 60 in Specification 1,065,881 and valve 77 corresponds to valve 23 of Specification 967,163.
