Bucket cover for excavating implements

An excavating implement comprising a clam-shell bucket, said clam-shell bucket having first and second opposing sections, each of said first and second sections having substantially closed opposing side walls which are connected by an arcuate outer wall, each of said side walls and said outer walls having an uppermost edge portion defining openings into said first and second sections of said clam-shell bucket, means for pivotally joining said first and second sections of said clam-shell bucket, at least one cover means, said cover means having a substantially imperforate central body portion and a continuous outer edge portion, said central body portion of said cover means being formed of a flexible material so as to be expandable outwardly with respect to said openings defined by said uppermost edge portions of said side and outer wall portions of said first and second sections, said outer edge portion being configured to cooperatively seat with said uppermost edge portions of said side walls and said outer walls of said first and second sections, said central portion of said cover means closing the openings defined by said uppermost edge portions of said side walls and said outer wall of said first and second sections.

An excavating implement comprising a bucket means, at least one pivotable boom element, means for pivotally mounting said bucket means to said at least one boom element so that said bucket means is pivotable to be extended from or pivoted toward said at least one boom element, said bucket means having upper edge portions defining an opening therein, a cover means, means for mounting said cover means to said at least one boom element adjacent said bucket means, said cover means including a substantially imperforate central body portion and an outer frame portion, said central body portion of said cover means being formed of a flexible material so as to be expandable outwardly with respect to said opening in said bucket means as said bucket means is moved toward said cover means, said outer frame portion being of a configuration to cooperatively seat with said upper edge portions of said bucket means so as to seal said cover means in relationship thereto, whereby said cover means is engagable with said upper edge of said bucket means when said bucket means is pivoted toward said at least one boom element.

In excavating equipment having an excavating bucket carried by a boom element which bucket has at least one opening defined by edge portions in which scooped material may be extended as the material is lifted by the bucket, the improvement comprising a cover means, said cover means having a continuous and generally imperforate central body portion and continuous side edge portions, said central body portion being formed of a yieldable material so as to be expansible away from the bucket so as to accommodate varying volumes of scooped material which may extend outwardly of the bucket opening, said side edge portions of said cover means being of configuration to cooperatively engage and continuously seat with the edge portions defining the opening into the bucket, said side edge portions of said cover means being formed of a yieldable material so as to accommodate for obstructions between said side edge portions and the edge portions defining the opening into the bucket, whereby said cover means covers the opening into the bucket to prevent spillage from the bucket.
