Abstract: A coupling particularly for use with colliery roadway supports. The coupling between an upright channel section or `I` beam and a crown beam of a similar cross-section is formed from two plates. At least a first of the plates is formed so as to lie between opposed flanges of the upright and opposed other of the two plates. The first plate extends beyond the head of the upright to a lip portion hooking all its width over the lower flange of the crown beam with preferably a bolt passing through the lip portion, the crown beam and opposed other plate. The clamping of the two plates together by the bolt or bolts securing the upright to the crown beam achieves a high resistance to lateral loading on the assembled beams to form a support.

Abstract: A coupling for tubular scaffolding including a boss mounted on a standard by a pin or by welding and a wedge ring rotatably encircling and co-planar with the boss.Radial insets in the boss combine with the ring to form apertures in which pegs are located, the pegs being attached to the ends of ledgers and transoms. The inner face of the wedge ring has sloping wedge surfaces in the vicinity of the apertures which alter the radial dimension of the apertures. Thus, when a peg is located in an aperture the wedge ring can be rotated to wedge the peg firmly in the aperture.The problem existing prior to the invention was the difficulty of securing ledgers and transoms. This has to be done by screw couplings or by getting above the coupling in order to tighten it. The coupling of the invention can be operated from below, i.e. by a person standing on erected scaffolding.
