Abstract
Abstract A combination attachment for a front-end loader having a lift apparatus attached to a conventional loader bucket is disclosed. The lift apparatus is mounted on the rear wall of the loader bucket and is suited for the lifting, gripping and moving of loads too wide for the loader bucket. The lift can be a conventional pair of fork tines or a platform and is powered by one or more hydraulic cylinders. The lift apparatus is disposed to permit both the lift and the loader bucket to be used simultaneously. The hydraulic cylinders further permit the lift apparatus to grip a load between the loader bucket floor and the lift fork or platform.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
A combined bucket and lift apparatus for attachment to a vehicle, comprising: a loader bucket having a bottom wall; a lifting member; and support means for adjustably suspending said lifting member below said loader bucket in a plane substantially parallel to said bucket bottom wall; said support means comprising hydraulic means secured between said bucket and said lifting member for raising and lowering said lifting member parallel to the bottom wall of the bucket to allow materials to be lifted and held between the lifting member and the bottom wall of the bucket.
Claim 2
Dependent Claim
93 words
A combined bucket and lift apparatus for attachment to a vehicle, comprising: a loader bucket having a bottom wall; a lifting member; and support means for adjustably suspending said lifting member below said loader bucket in a plane substantially parallel to said bucket bottom wall; said support means comprising hydraulic means secured between said bucket and said lifting member for raising and lowering said lifting member parallel to the bottom wall of the bucket to allow materials to be lifted and held between the lifting member and the bottom wall of the bucket.
Claim 3
Dependent Claim
38 words
The apparatus as claimed in claim 1, wherein said support means additionally comprises telescopic guide means secured between said lifting member and said bucket for slidably guiding said lifting member for movement parallel to said bucket bottom wall.
Claim 4
Dependent Claim
106 words
The apparatus as claimed in claim 2, wherein said bucket has a rear wall extending substantially perpendicular to said bottom wall, and said lifting member has a rear edge, said telescopic guide means extending between said bucket rear wall and said rear edge of said lifting member in a direction perpendicular to the plane of said lifting member, and comprising a first part projecting upwardly from the rear edge of said lifting member and a second part secured to said bucket rear wall, one of said parts comprising a guide bar and the other part comprising a hollow tubular member for slidably receiving said guide bar.
Claim 5
Dependent Claim
46 words
The apparatus as claimed in claim 3, including a pair of spaced telescopic guide means extending between said bucket rear wall and lifting member rear edge, each guide means comprising a guide bar and a hollow tubular member for telescopic sliding engagement with said guide bar.
Claim 6
Dependent Claim
37 words
The apparatus as claimed in claim 1, wherein said hydraulic means comprises at least one hydraulic cylinder and piston secured between said bucket and lifting member and extending perpendicular to said bucket bottom wall and lifting member.
Claim 7
Dependent Claim
15 words
The apparatus as claimed in claim 1, wherein said lifting member comprises a lifting fork.
Claim 8
Dependent Claim
15 words
The apparatus as claimed in claim 1, wherein said lifting member comprises a lifting plate.
Claim 9
Dependent Claim
112 words
A lifting and grappling apparatus for attachment to a loader bucket, comprising: a planar lifting member; suspending means for suspending the lifting member from a loader bucket in a plane parallel to the bottom wall of the bucket, the suspending means comprising a hydraulic lifting mechanism secured at one end to said lifting member and having mounting means at the other end for mounting on a rear surface of a loader bucket, the lifting mechanism comprising means for raising and lowering said lifting member relative to the bottom wall of a loader bucket to allow materials to be lifted and held between the bottom wall of the bucket and the lifting member.
Claim 10
Dependent Claim
112 words
A lifting and grappling apparatus for attachment to a loader bucket, comprising: a planar lifting member; suspending means for suspending the lifting member from a loader bucket in a plane parallel to the bottom wall of the bucket, the suspending means comprising a hydraulic lifting mechanism secured at one end to said lifting member and having mounting means at the other end for mounting on a rear surface of a loader bucket, the lifting mechanism comprising means for raising and lowering said lifting member relative to the bottom wall of a loader bucket to allow materials to be lifted and held between the bottom wall of the bucket and the lifting member.
Claim 11
Dependent Claim
153 words
A combined bucket and lift apparatus for attachment to a vehicle, comprising: a loader bucket having a bottom wall; a lifting member; suspending means connected between the loader bucket and lifting member for adjustably suspending the lifting member below the bucket in a plane substantially parallel to the bottom wall of the bucket; the suspending means comprising hydraulic means extending perpendicular to said lifting member for raising and lowering said lifting member in planes parallel to the bottom wall of the bucket and at least one telescopic guide means extending transversely between the bucket and lifting member for guiding said lifting member as it moves up and down, said guide means comprising a first part secured to the bucket and a second part secured to the lifting member, one of the parts comprising a guide bar and the other part comprising a hollow tubular member for telescopic sliding engagement with said guide bar.
Claim 12
Dependent Claim
153 words
