Abstract
A steel connector for joining the steel cable ends of a conveyor belt is provided. The connector comprises a pair of tubular sleeves--one of which is slipped onto each cable end. Each sleeve has a bore having an inner section of reduced diameter relative to the outer section. The cable end is expanded radially, by driving a cone into its end, and then the expanded end is wedged tightly into the inner section of the sleeve to fix them together. Bridging members are threaded into the outer sections of the two sleeves to hold them together in lineal alignment. The bridging members are operative to permit the sleeves to flex relative to each other.
Claims4
A connector for joining two cable ends in a conveyor belt comprising:
- a pair of sleeves, each sleeve forming a longitudinal bore extending therethrough, said bore having an inner section of reduced cross-sectional area relative to the remainder of the bore, said bore being of sufficient cross-sectional area so that each sleeve can slip onto one of the cable ends to be joined;
- a pair of wedge means, each adapted to be embedded in one cable end, once the sleeve has been slipped onto the cable end, to expand said cable end sufficiently so that the expanded end is small enough to enter the bore's outer section but is too large to pass through the bore's inner section, whereby each sleeve may be securely attached to one cable end;
- and
- bridging means for interconnecting the sleeves, said bridging means comprising
- rigid elongated first means extending between the sleeves,
- second means for connecting one end of the first means with one sleeve and enabling said first means to pivot relative to the longitudinal axis of said sleeve,
- and third means for connecting the other end of the first means with the other sleeve and enabling said first means to pivot relative to the longitudinal axis of said sleeve,
- whereby the bridging means is operative to hold the sleeves together in substantially aligned lineal relation while permitting the connector to flex, to a limited extent, when passing around a conveyor roll.
A connector for joining two cable ends in a conveyor belt, comprising:
- a pair of sleeves, each such sleeve forming a longitudinal bore extending therethrough, said bore having an internally threaded outer section and an inner section of reduced cross-sectional area relative to that of the outer section, the bore being of sufficient cross-sectional area so that each sleeve can slip onto one of the cable ends to be joined;
- a pair of wedge means, each adapted to be embedded in one cable end, once the sleeve has been slipped onto the cable end, to expand said cable end sufficiently so that the expanded end is small enough to enter the bore's outer section but is too large to pass through the bore's inner section, whereby each sleeve may be securely attached to one cable end;
- and
- bridging means for interconnecting the sleeves, said bridging means being operative to hold the sleeves together in substantially aligned lineal relation while permitting of limited tilting movement of each sleeve relative to the longitudinal axis of the connector, whereby said connector may flex, to a limited extent, when passing around a conveyor roll, said bridging means comprising
- a shaft, having a removable enlarged head at each end, for extending into each of the bore outer sections,
- a pair of externally threaded rings adapted to be mounted on the shaft between the heads and to thread into the outer sections of the sleeves, each said ring having a longitudinal bore extending therethrough which is sized to loosely accommodate the shaft but is sufficiently small so that the ring may not pass over the enlarged head, said rings being adapted to connect the sleeves with the shaft, to restrain the contained heads within the sleeves while permitting of some tilting of the shaft, and to be screwed inwardly or outwardly in the sleeves to adjust the spacing between the cable ends;
- each shaft head and associated ring having rounded mating shoulders which permit of limited flexing of the connector.
