Abstract

909,274. Mine roof supporting bars. VANWERSCH, L., VANWERSCH, A., and VANWERSCH, P. June 1, 1959 [May 30, 1958; Oct. 27, 1958], No. 18626/59. Class 20 (2). [Also in Group XXV] In bars for supporting mine roofs having end to end fork and tongue engagement and joined by a pin 3 in apertures in both bars and a wedge 4 in apertures in the fork 1 of the already positioned bar and engaging the upper inclined surface of the tongue 2 of the bar that is being positioned, to force it against the mine roof, the pin or the wedge has a friction member 5 to retard their movement. The member 5 is a spring ring surrounding the narrow end of the wedge and has projections engaging grooves 4a in the wedge which have abutments to engage the projections to prevent withdrawal of the wedge, the ring 5 being retained by a ring 6. The end of the wedge is sufficiently narrow to allow it to be passed round the tip of the tongue 2. In a modification the member 5 is not a complete ring and is secured to the bar by a rivet and in another modification a spring ring prevents rotation of the member 5. In a still further modification the pin 3 is provided with a friction member.
