Abstract
Abstract An attachment for installation on the bucket of a front end loader includes a platform which alternately functions as a rigid extension of the bottom or top of the bucket. The platform is pivotally carried between the outer ends of a pair of parallel arms which are pivoted at their other ends to the opposite sides of the bucket. The platform seats firmly on the blade which extends from the bottom of the bucket and may be moved upwardly to a position wherein it may be secured on top of the bucket. A pair of stop plates control the pivoting of the platform as the arms are raised or lowered.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
An attachment for a vehicle carrying a bucket thereon, said bucket having a top, a bottom, and a pair of opposite sides, said attachment comprising: arm means adapted for pivotal connection to said bucket; a platform pivotally coupled to said arm means, said platform and arm means being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top; and means for locking said platform to said bucket in rigid extension from said bucket top.
Claim 2
Dependent Claim
94 words
An attachment for a vehicle carrying a bucket thereon, said bucket having a top, a bottom, and a pair of opposite sides, said attachment comprising: arm means adapted for pivotal connection to said bucket; a platform pivotally coupled to said arm means, said platform and arm means being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top; and means for locking said platform to said bucket in rigid extension from said bucket top.
Claim 3
Dependent Claim
32 words
An attachment as in claim 1, including means for selectively controlling the pivotal movement of said platform with respect to said arm means as the latter pivots with respect to said bucket.
Claim 4
Dependent Claim
33 words
An attachment as in claim 1, wherein said platform includes a transverse channel positioned to receive an edge of said bucket bottom to secure said platform in rigid extension from said bucket bottom.
Claim 5
Dependent Claim
24 words
An attachment as in claim 3, wherein said channel includes spaced upper and lower legs, said upper leg being shorter than said lower leg.
Claim 6
Dependent Claim
148 words
An attachment for a vehicle carrying a bucket thereon, said bucket having a top, a bottom, and a pair of opposite sides, said attachment comprising: a pair of parallel arms adapted for pivotal connection at one end to the respective opposite sides of said bucket; a platform pivotally coupled to said arms at the other ends thereof, said platform and arms being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top; and a stop member engageable with said platform and one of said arms at a position offset from the pivot connection therebetween to limit pivotal movement of said platform with respect to said arms in one pivotal direction, while permitting free pivotal movement of said platform with respect to said arms in the opposite pivotal direction.
Claim 7
Dependent Claim
148 words
An attachment for a vehicle carrying a bucket thereon, said bucket having a top, a bottom, and a pair of opposite sides, said attachment comprising: a pair of parallel arms adapted for pivotal connection at one end to the respective opposite sides of said bucket; a platform pivotally coupled to said arms at the other ends thereof, said platform and arms being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top; and a stop member engageable with said platform and one of said arms at a position offset from the pivot connection therebetween to limit pivotal movement of said platform with respect to said arms in one pivotal direction, while permitting free pivotal movement of said platform with respect to said arms in the opposite pivotal direction.
Claim 8
Dependent Claim
24 words
An attachment as in claim 5, wherein said stop member is oriented to retain said platform at an angle with respect to said arms.
Claim 9
Dependent Claim
82 words
An implement for a vehicle, said implement comprising: a bucket adapted to be mounted on the vehicle, said bucket having a top, a bottom, and a pair of opposite sides; arm means pivotally connected to said bucket; and a platform pivotally coupled to said arm means, said platform and arm means being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top.
Claim 10
Dependent Claim
82 words
An implement for a vehicle, said implement comprising: a bucket adapted to be mounted on the vehicle, said bucket having a top, a bottom, and a pair of opposite sides; arm means pivotally connected to said bucket; and a platform pivotally coupled to said arm means, said platform and arm means being pivotally movable between a first position wherein said platform forms an extension of said bucket bottom and a second position wherein said platform forms an extension of said bucket top.
Claim 11
Dependent Claim
32 words
An implement as in claim 7, including means for selectively controlling the pivotal movement of said platform with respect to said arm means as the latter pivots with respect to said bucket.
