Abstract
A two-piece cutting edge construction wherein a plurality of adapters are mounted on the mold board each having releasably locked thereto a cutting edge; the sidewalls of the adapters and cutting edges being recessed for the receipt of longitudinally (forwardly/rearwardly) stabilizing pins; the lock for releasably coupling the cutting edge to the adapter including two legs resiliently inner connected by a compression spring with the lock being insertable and removable by forces extending transversely of the forward/rearward mounting and unmounting direction of the cutting edge.
Claims13
A multi-part cutting edge structure comprising:
- a plurality of adapter parts adapted to be secured to an earth moving unit in side-by-side relation and projecting forwardly therefrom,
- a cutting edge part adapted to be removably mounted on each adapter part by rearward movement relative thereto and projecting forwardly to provide side-by-side cutting edge parts,
- each of said parts being generally plate-like and having forwardly-extending side edges, each side edge having a forwardly-extending groove therein to cooperate with the groove of the adjacent part in defining a forwardly-extending, elongated, generally tubular recess,
- an elongated pin in each recess extending forwardly to span both a pair of adapter parts and their associated cutting edge parts to stabilize the same,
- each adapter part and the cutting edge part mounted thereon being equipped with alignable openings for the receipt of a lock, and
- a lock extending through said openings when aligned and rigidly coupling said parts together against forward disassembling movement of said cutting edge part, said lock including resilient means for lock removal by the application of a force transverse to the direction of said rearward movement.
