Abstract: A cable coupler includes a body having a first end, a second end, and first and second passageways sized and shaped to receive a cable, with each passageway including a tapered portion. A wedge assembly is disposed in each tapered portion to secure a cable to the body. A clip assembly is attached to the body adjacent the tapered portion of each of the passageways and is shiftable between a closed position in which the clip assembly is positioned to prevent an adjacent one of the wedge assemblies from exiting the corresponding passageway and an open position in which the adjacent wedge assembly is insertable into the tapered portion of the corresponding passageway.

Abstract: A low-profile mine roof support device comprises a roof plate and a barrel. The barrel includes a nose portion, a shoulder portion, and a tapered bore for receiving a cable to secure the roof plate to the mine roof. The shoulder portion of the barrel comprises a convex surface that seats against the plate. So configured, a majority of the barrel, which includes the nose portion and the tapered bore, passes through the plate and into a drilled hole formed in the mine roof, thereby advantageously minimizing the extent to which the support device extends into the workspace of the mine without sacrificing the length of the barrel.
