Wear cap and components useable therewith

A wear cap to protect a wearable surface, said wear cap including a pair of opposite ends, a wear surface adapted to be remote from the wearable surface, a mounting surface adapted to face the wearable surface, a plurality of tabs projecting outward from said mounting surface and in the general direction of one of said ends to be received in recesses defined in the wearable surface, at least one tab being spaced closer to one said end than at least one other said tab, and an aperture opening in said mounting surface extending through said wear cap for receiving a lock to secure the wear cap to the wearable surface, said opening having a bearing surface for abutting the lock.

A wear cap to protect a wearable surface, said wear cap having a wear surface adapted to be remote from the wearable surface, a mounting surface adapted to face the wearable surface, a pair of opposite ends, a plurality of tabs projecting outward from said mounting surface at acute angles and in generally the same direction toward one of said ends to be received in recesses defined in the wearable surface, at least one of said tabs being spaced closer to one end than another of said tabs.

A lock for securing a wear cap to a wearable surface, said lock comprising a rigid hub having a front bearing surface and a rear bearing surface each having a peripheral edge, at least one shaft projecting from one of said bearing surfaces near said peripheral edge, said hub being rotatable about said shaft between a release position and a locked position, and at least one resilient latch extending outward to releasably retain said hub in said locked position.

An adapter for an excavating tooth comprising a rear mounting end and a forwardly projecting nose for mounting a wear member, said mounting end having a wearable surface provided with at least one front recess and at least one rear recess, each said recess having a shoulder adapted to engage a tab for securing a wear cap, all of said shoulders being inclined at acute angles relative to said wearable surface in the same general direction.

An adapter for an excavating tooth comprising a rear mounting end and a forwardly projecting nose for mounting a wear member, said mounting end having a wearable surface provided with a plurality of recesses each having a shoulder adapted to engage a tab for securing a wear cap, at least one of said recesses being spaced farther from said nose than at least one other of said recesses, and at least one of said recesses having a larger opening in said wearable surface than at least one other of said recesses to receive a lock therein for securing the wear cap to the adapter.
