See-through bucket
First Claim
1. A material-handling element used with a mobile material-handling machine having an operator'"'"'s control cab, comprising:
- a body portion including a pair of sidewalls and wall means, interconnecting said sidewalls, for forming a material-receiving channel, said wall means defining a transversely disposed digging edge; and
means joined to at least one of said sidewalls and wall means, for joining said body portion to said machine, said wall forming means being interposed between said digging edge and said control cab with said body portion in a first position relative to said machine,said wall forming means defining at least one aperture adjacent one of said sidewalls located in the line-of-sight between the operator stationed in said cab and said digging edge with said body portion in said first position, and a mirror joined to said body portion and aligned to the plane of said at least one aperture at an acute angle whereby the operator stationed in said cab and looking in the direction of said at least one aperture and mirror sees a portion of said digging edge out of the line of sight passing through said at least one aperture, whereby said operator can accurately position said body portion in said first position using said digging edge as a guide.

Abstract
A material handling element or bucket is formed from two sidewalls and a backwall. The backwall has one or more apertures postioned in such a manner that the operator manipulating the bucket can see a portion of the leading edge of the bucket. In one embodiment, the apertures are positioned in such a manner that the leading edge can be viewed directly or in combination with one or more mirrors. In another embodiment, the apertures are positioned in such a manner so that the operator can sight one or more of the sidewalls of the bucket using those sidewalls as a guide for positioning the leading edge of the bucket.
