Abstract: A truss shoe for a mine roof truss comprises a base having a pair of ends, a curved side extending between the ends, a top side, and a bearing surface. The shoe includes an angled stanchion having a bore and a housing having a tapered bore, with a recess between the housing and stanchion. A retainer is sized to fit in the recess, with the retainer having an aperture disposed adjacent an end such that the blocks a portion of the opening of the bore in the housing to retain a wedge assembly in the tapered bore.

Abstract: A truss shoe for use on a mine roof truss having at least one inclined bolt and at least one horizontal cross member comprises a base including a first end, a second end, a first side and a second side extending between the first and second ends, a generally planar bearing surface, and a top side disposed opposite the bearing surface, the bearing surface arranged for contact with the mine roof. A stanchion is formed on the top side and includes a bore extending from a top end of the stanchion through the bearing surface, the bore sized to receive the inclined bolt. A bracket is formed on the top side and includes a laterally extending slotted bore sized to receive the horizontal bolt. A portion of the first end and a portion of the first side cooperate to form a curved edge.

Abstract: A mine roof bolt for use with a cable comprises a barrel having a first end and a second end, the second end having a rounded surface, a bore extending through the barrel between the first end and the second end and including a tapered portion, the bore sized to receive the cable, a pair of wedges sized for placement in the tapered portion of the bore and adapted to frictionally engage a cable disposed in the tapered portion of the bore, a recess defined in the first end of the barrel, and a driving nut sized for insertion in the recess and adapted for engagement by a driving tool.
