Abstract
Shrouds are secured to earth-working edges of many kinds of earth working equipment to extend the service life of the equipment. The shrouds include opposed surfaces to define a cavity to receive the edge. Each of the opposed surfaces includes a recess to receive a boss on the edge, wherein the longitudinal axis of the recess on the first surface is angularly oriented in a lateral direction to the longitudinal axis of the recess on the second surface.

A shroud for an earth-working edge on earth working equipment comprising a front end and a rearwardly-opening cavity including opposed first and second surfaces to straddle the edge and a front surface extending between the first and second surfaces, the first surface including a recess with opposed planar bearing surfaces to bear against a boss on the edge, wherein the bearing surfaces converge toward the front surface.
A shroud for an earth-working edge on earth working equipment comprising a front end and a rearwardly-opening cavity including opposed first and second surfaces to straddle the edge and a front surface extending between the first and second surfaces, each of the first and second surfaces including a recess to receive a boss on the edge, and each said recess including opposed bearing surfaces to bear against the received boss, wherein the opposed bearing surfaces in the recess in the first surface converge toward the front surface.
A shroud for an earth-working edge on earth working equipment comprising a front end and a rearwardly-opening cavity including opposed first and second surfaces to straddle the edge and a front surface extending between the first and second surfaces, the first surface including a first recess to receive a first boss on the edge, the first recess having a first longitudinal axis, the second surface including a second recess to receive a second boss on the edge, and the second recess having a second longitudinal axis that is angularly oriented in a lateral direction to the first longitudinal axis.
A shroud for an earth-working edge on earth working equipment comprising a front end and a rearwardly-opening cavity including opposed first and second surfaces to straddle the edge and a front surface extending between the first and second surfaces, the first surface including a first recess with opposed first bearing surfaces to bear against a boss on the edge, the first bearing surfaces converging toward the front surface, and the second surface including a second recess with opposed second bearing surfaces to bear against a boss on the edge, wherein one of the first bearing surfaces is parallel to the second bearing surfaces and the other first bearing surface is transverse to the second bearing surfaces.
A shroud for a bucket lip having a forward-facing leading surface, primary segments where the leading surface extends parallel to the width of the bucket, and transition segments where the leading surface is inclined to the primary segments, the shroud comprising a front end, a rearwardly-opening a cavity to receive the lip such that the shroud overlies a portion of the leading surface, the cavity including first and second opposed surfaces and a front surface extending between the first and second surfaces to oppose the leading surface, and a lock-receiving opening having an elongate configuration with a length along which a major axis extends, wherein the front surface and the major axis are generally parallel to the leading surface in the transition segment received in the cavity.
A lip assembly for an earth working bucket comprising:
- a lip having a forward-facing leading surface, primary segments where the leading surface extends parallel to the width of the bucket, and transition segments where the leading surface is inclined to the primary segments;
- and
- at least one shroud secured to a transition segment, the shroud including a front end, a rearwardly-opening a cavity to receive the lip such that the shroud overlies a portion of the leading surface, the cavity including first and second opposed surfaces and a front surface extending between the first and second surfaces to oppose the leading surface, and a lock-receiving opening having an elongate configuration with a length along which a major axis extends, wherein the front surface and the major axis are generally parallel to the leading surface in the transition segment received in the cavity.
A lip for an excavating bucket comprising a forward-facing leading surface, an inner surface, an outer surface, primary segments where the leading surface extends parallel to the width of the bucket, transition segments where the leading surface is inclined to the primary segments, at least one transition segment including a first boss with a first longitudinal axis on the inner surface and a second boss with a second longitudinal axis on the outer surface that is angularly oriented in a lateral direction to the first longitudinal axis.
A lip for an excavating bucket comprising a forward-facing leading surface, an inner surface, an outer surface, primary segments where the leading surface extends parallel to the width of the bucket, transition segments where the leading surface is inclined to the primary segments, a plurality of first bosses each being identical and having a first longitudinal axis on the inner surface and a plurality of second bosses each being identical and having a second longitudinal axis on the outer surface, wherein the first longitudinal axis of at least one of the first bosses is angularly oriented in a lateral direction to at least one of the second longitudinal axes.
A lip for an excavating bucket comprising a forward-facing leading surface, an inner surface, an outer surface, primary segments where the leading surface extends parallel to the width of the bucket, transition segments where the leading surface is inclined to the primary segments, a plurality of bosses on one of the inner and outer surfaces, the bosses being identical with each having a longitudinal axis, and at least one said boss being oriented such that its longitudinal axis is angled relative to at least one other of the bosses.
A lip for an excavating bucket comprising a forward-facing leading surface, an outer surface, an inner surface with a beveled portion adjacent the leading surface and a rear portion rearward of the beveled portion, a plurality of first bosses fixed to the beveled portion and entirely forward of the rear portion, and a plurality second bosses separate from the first bosses fixed to the outer surface.
A process for installing a wear member on an earth-working edge on earth working equipment, the process comprising:
- providing a shroud including spaced legs forming a cavity wherein each leg includes a recess defined by opposed bearing surfaces that receives a boss on the edge;
- moving the shroud rearward so the edge is received into the cavity, one boss slides along the opposed bearing surfaces of one said recess and one boss approaches one of the bearing surfaces in the other recess;
- and
- inserting a lock into an opening in the shroud to engage the shroud and one of the bosses to secure the shroud to the edge.
