Abstract: A chain breaker comprising a lever bar, a U-shaped frame including a pair of opposing arms each having a bore extending therethrough for selectivey receiving the lever bar, the lever bar including a bore extending transversely therethrough for receiving a pin of a chain, means for maintaining the received lever bar with the pin receiving bore at a predetermined orientation, means for locating the received, oriented lever bar with the pin receiving bore thereof at a predetermined longitudinal position, a push out screw including an extractor pin, support means secured to the U-shaped frame for threadedly receiving the push out screw with the extractor pin in coaxial relation with the oriented and longitudinally positioned pin receiving bore of the received lever bar, the top of the U-shaped member including a through-bore for receiving the push out screw, and means for selectively rotating the threadedly received push out screw.

Abstract: A master link assembly for releasably coupling the opposing ends of a series of articulated links to form a chain, wherein the opposing ends are defined by a pair of roller link assemblies each having a pair of opposing link plates with pitch holes extending between the opposing faces thereof and a pair of tubular bushings press-fitted thereinto comprising first and second link plates each including a pair of pitch holes extending between the opposing faces thereof, a pair of connecting pins selectively configured for slidable insertion into the tubular bushings and for insertion into the pitch holes of the first and second link plates, means for limiting the separation of the first and second link plates to a predetermined maximum separation, the limiting means including a bifurcated clip spring selectively configured for placement about the connecting pins adjacent the outer face of one of the first and second link plates, a locking plate having a U-shaped configuration, wherein the legs of the locking plat
