Abstract

876,483. Mine roof supports. EGGEMANN, W., and CAMPENHAUSEN, VON E., [trading as SCHWARZ KOMM.-GES., HERMANN]. Jan. 30, 1958, No. 3053/58. Class 20(2) A hydraulic pit prop comprising a tube 5 telescoping within a tube 8 which has a pivoted head 39 has a convex base which pivots within a flanged wall 7 on the floor of a housing 4 which acts as a hydraulic fluid reservoir. The head 39 has a convex lower surface 40 pivoting in a concave housing 38 provided with retaining lugs 41. In operation a detachable electric motor 46 is applied to a pump 23 which draws oil from the reservoir 4 through a filter 26, pipe 27, valve 28 and pipe 12 into the tubes 5, 8 forcing them apart to extend the prop. To release the prop, valve 28 is operated to connect pipes 12 and 30, oil also being pumped via pipe 29 and bore 45 into the annular space 42 between the head of tube 5 and tube 8. A relief-valve 13 is provided. A flexible ring 22 held by a flanged metal ring 18 bears on a ring 19 having flexible seals 20 so as to maintain the tube 8 upright. A double acting jack 36 pivoted between the prop and a conveyer 37 is operated by the valve 28 to advance the conveyer when the prop is set. Specification 876,484 is referred to.
