Master link for cushioned track

Claim 2

A master link assembly in a longitudinal track chain comprising a first link portion mounted on a first pivot means for rotational movement about an axis thereof, a second link portion including a second pivot means remote from said first pivot means at least partially overlapping and abutting said first link portion and arcuately shaped interengaging locking means formed on overlapping surface portions of said first and second link portions for connecting them together, said locking means at least substantially disposed at a constant radius from the axis of one of said pivot means.

Claim 3

The master link defined in claim 1 wherein the locking means comprises a plurality of arcuate and concentric serrations.

Claim 4

The invention of claim 1 wherein said master link assembly comprises a laterally spaced pair of first link portions and a laterally spaced pair of second link portions, and said pivot means comprises an elongated pivot pin connecting said pair of first link portions together.

Claim 5

The invention of claim 3 wherein said pair Of first link portions are positioned between said pair of second link portions, one of said locking means connecting each one of said first link portions to a respective one of said second link portions.

Claim 6

A master track link comprising two separable parts, one end of each part defining respectively a pin bore, and a bushing bore longitudinally spaced from the pin bore, and the other ends of said parts defining mating surfaces intermediate the pin bore and the bushing bore and perpendicular to said bores, one of said mating surfaces being provided with at least one projection which extends into corresponding depressions formed in said other mating surface, said depressions being formed so as to accommodate said projections as one part is rotated with respect to the other in a plane parallel to said mating surfaces.

Claim 7

A master track link comprising two separable parts, one end of each part defining respectively a pin bore, and a bushing bore longitudinally spaced from the pin bore, and the other ends of said parts defining mating surfaces intermediate the pin bore and the bushing bore and perpendicular to said bores, one of said mating surfaces being provided with at least one projection which extends into corresponding depressions formed in said other mating surface, said depressions being formed so as to accommodate said projections as one part is rotated with respect to the other in a plane parallel to said mating surfaces.

Claim 8

The master link defined in claim 5 wherein said projection is an arcuate notch and said depression is an arcuate groove.

Claim 9

The master link defined in claim 5 wherein the mating surfaces are provided with matching multiple arcuate serrations.

Claim 10

The invention of claim 5 wherein the serrations are concentric about an axis of rotation of one of the parts.

Claim 11

In a vehicle track comprising a plurality of pins, which include bushings along the central portion thereof, interconnected by a plurality of pairs of links wherein each link of each pair of links overlaps an adjacent link of an adjacent pair of links so that outer overlapping first end portions of a pair of links receive the ends of a pin in bores found therein and are positioned without inner, overlapped second end portions of the adjacent pair of links which receive the bushing on said pair in bores formed therein, a master coupling comprising a pair of links comprising a pair of pin bore end parts and a pair of bushing bore end parts, one of said pairs of parts overlapping the other of said pairs of parts laterally outboard thereof and engaging said other pair of parts at abutting, mating surfaces extending perpendicular to said pins, said mating surfaces being provided with arcuate serrations whereby the pairs of parts are engageable by rotation of one pair of parts about their bore ends relative to the other pair of parts.

Claim 12

In a vehicle track comprising a plurality of pins, which include bushings along the central portion thereof, interconnected by a plurality of pairs of links wherein each link of each pair of links overlaps an adjacent link of an adjacent pair of links so that outer overlapping first end portions of a pair of links receive the ends of a pin in bores found therein and are positioned without inner, overlapped second end portions of the adjacent pair of links which receive the bushing on said pair in bores formed therein, a master coupling comprising a pair of links comprising a pair of pin bore end parts and a pair of bushing bore end parts, one of said pairs of parts overlapping the other of said pairs of parts laterally outboard thereof and engaging said other pair of parts at abutting, mating surfaces extending perpendicular to said pins, said mating surfaces being provided with arcuate serrations whereby the pairs of parts are engageable by rotation of one pair of parts about their bore ends relative to the other pair of parts.

Claim 13

The master coupling of claim 9 wherein the pair of pin bore end parts engage the pair of bushing bore end parts outboard of the bushing bore end parts.

Claim 14

The master coupling of claim 9 wherein the pair of pin bore end parts engages the pin of bushing bore end parts inboard of the bushing bore end parts.

Claim 15

The master coupling of claim 9 wherein the abutting, mating surfaces are held in engagement by fastening means extending laterally through the overlapping surfaces.

Claim 16

A master link assembly comprising first and second laterally spaced master links each comprising overlapped first and second link portions, interengaging arcuately extending locking means formed on overlapped surface portions of the first and second link portions of each of said master links, said first link portions positioned between said second link portions, and means for attaching all of said link portions together.

Claim 17

A master link assembly comprising first and second laterally spaced master links each comprising overlapped first and second link portions, interengaging arcuately extending locking means formed on overlapped surface portions of the first and second link portions of each of said master links, said first link portions positioned between said second link portions, and means for attaching all of said link portions together.
