US Classification:

37450, 37455, 37454

Abstract:

A wear assembly for attaching wear members to a lip of an excavator includes a wear member, a boss and a lock. The lip includes an inner face, an outer face, a digging edge and a series of through-holes spaced rearward of the digging edge. The bosses are each fixed to a face of the lip at a position rearward of the through-holes. The wear members each include slots to receive the boss adjacent their rear ends, and openings for receiving the locks at a position forward of the bosses. The openings are aligned with the through-holes in the lip. The lock includes a wedge and spool arrangement.

Appl. No.:

10/425934

Inventors:

Terry L. Briscoe - Portland OR, US

Assignee:

Esco Corporation - Portland OR

International Classification:

E02F 9/28

US Classification:

37455, 37456, 37457, 403370, 4033744

Abstract:

A lock that includes a wedge and a spool are used to releasably secure separable components of an assembly together. The wedge and spool are threadedly coupled together to drive the wedge into and out of an opening in the assembly without hammering or prying. The direct coupling of the wedge and spool eliminates the need for bolts, washers, nuts and other hardware so as to minimize the number of parts. As a result, the lock is inexpensive to make, easy to use, and unlikely to become inoperative because of lost or broken parts or due to fines or other difficulties encountered in harsh digging environments. Further, the wedge can be driven into the assembly to provide the degree of tightness necessary for the intended operation and/or to re-tighten the assembly after incurring wear during use. A latch assembly is preferably provided to securely hold the wedge in place and avoid an undesired loss of parts during use.
