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 plate extend substantially perpendicularly from the top portion thereof and are in parallel spaced relation, the spacing being selected to correspond to the width of the spring clip, an aperture in the one link plate, an aperture in the locking plate top portion, and screw means for securing the locking plate to the one link plate.

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 said first and second link plates, means for limiting the separation of said first and second link plates to a predetermined maximum separation, said limiting means including a bifurcated clip spring selectively configured for placement about said connecting pins adjacent the outer face of one of said first and second link plates, a locking plate having a U-shaped configuration, wherein the legs of said locking plate extend substantially perpendicularly from the top portion thereof and are in parallel spaced relation, said spacing being selected to correspond to the width of said spring clip an aperture in said one link plate, an aperture in the top portion of said locking plate, and screw means for securing said locking plate to said one link plate.
Claim 3
Dependent Claim
27 words
A master link assembly according to claim 1, wherein the height of said locking plate legs is selected to correspond to the height of said spring clip.
Claim 4
Dependent Claim
46 words
A master link assembly according to claim 2, wherein said one link plate has a length greater than the distance between said connecting pins and further includes a pair of aperture means for selectively receiving the portions of said connecting pins extending beyond said spring clip.
Claim 5
Dependent Claim
15 words
A master link assembly according to claim 1, wherein said link plate aperture is tapped.
