Patent ID: 7900383

Claim:
An excavation bucket for use with a piece of machinery having an articulated arm, the excavation bucket comprising: a rigid member having a body wall and a pair of sidewalls, each of the sidewalls having a forward end, a rearward end, an upper end, and a lower end, the body wall connected to the rearward end of each of the sidewalls in such a way that the sidewalls are supported in a spaced apart relationship to one another and the sidewalls cooperate with the body wall to define an excavation bucket cavity with an open bottom, the rigid member having a connection member pivotally connectable to a portion of the articulated arm of the piece of machinery; and a resilient member having a front edge, a rear edge, a first lateral edge, and a second lateral edge, the first lateral edge connected to one of the sidewalls and the second lateral edge connected to the other sidewall such that the resilient member extends across the open bottom of the rigid member with the front edge positioned forward of the forward ends of the sidewalls so as to serve as a digging edge and the rear edge positioned rearward of the open bottom, the resilient member being fabricated of a polymeric material to deflect in response to pressure from impact and to return to a substantially non-deflected condition upon release of the pressure.
