Abstract
Abstract A round bale loader attachment is adapted for use with conventional farm tractor front end loaders and has forwardly extending, generally parallel arms mounted for free pivotal movement about longitudinal axes thereof, permitting a semi-cradling of the bales for efficient handling with minimal lateral squeezing. Simple structure is provided for varying the space between the arms, and hitch means secure the attachment to the loader for manipulation by the tractor operator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A device for handling a round hay bale having a substantially cylindrical surface and opposite bases comprising: (a) a frame adapted for manipulation by a tractor loader; (b) a pair of projecting pin members on said frame; (c) means for moving said pin members laterally toward and away from each other; (d) a pair of generally parallel and projecting arms respectively having a bale engaging inner surface and mounted on said projecting pin members, said arms being freely pivotable on said pin members about respective longitudinal axes thereof; (e) said arms being in cross section a greater height than width with said pin member having mounted above the respective center of gravity of said arms whereby said arms hang vertically oriented when not in lifting contact with said bale surface, said arms pivoting so that said inner surfaces conform to said bale surface when in lifting contact therewith and subsequently return to vertical orientation when the bale is released.
Claim 2
Independent Claim
159 words
A device for handling a round hay bale having a substantially cylindrical surface and opposite bases comprising: (a) a frame adapted for manipulation by a tractor loader; (b) a pair of projecting pin members on said frame; (c) means for moving said pin members laterally toward and away from each other; (d) a pair of generally parallel and projecting arms respectively having a bale engaging inner surface and mounted on said projecting pin members, said arms being freely pivotable on said pin members about respective longitudinal axes thereof; (e) said arms being in cross section a greater height than width with said pin member having mounted above the respective center of gravity of said arms whereby said arms hang vertically oriented when not in lifting contact with said bale surface, said arms pivoting so that said inner surfaces conform to said bale surface when in lifting contact therewith and subsequently return to vertical orientation when the bale is released.
Claim 3
Dependent Claim
30 words
The device as set forth in claim 1 wherein: (a) said frame includes a front beam, a rear beam, and spaced apart side beams joined together in a rectangular arrangement.
Claim 4
Dependent Claim
36 words
The device as set forth in claim 2 including: (a) an elongated bale stabilizer mounted on said frame and spaced vertically therefrom, said stabilizer projecting forwardly not substantially less than the forward-most portion of said frame.
Claim 5
Dependent Claim
35 words
The device as set forth in claim 1 wherein: (a) said frame includes a rear beam, and further including hitch means on said rear beam and adapted to be removably attached to said tractor loader.
Claim 6
Dependent Claim
44 words
The device as set forth in claim 1 wherein: (a) said frame includes a transversely extending front beam; and (b) a pair of sleeves respectively supporting said arms, said sleeves engaging said front beam and slidable therealong for varying the distance between said arms.
Claim 7
Dependent Claim
25 words
The device as set forth in claim 5 including: (a) slide limit means on said front beam for limiting the sliding range of said sleeves.
Claim 8
Dependent Claim
40 words
The device as set forth in claim 5 wherein said pin moving means includes: (a) an extendible motor member having opposite ends respectively operably attached to said sleeves and functional to move said sleeves toward and away from each other.
Claim 9
Dependent Claim
52 words
The device as set forth in claim 1 wherein: (a) each of said arms has a lower surface and a front end; and including (b) an elongated runner attached to each of said lower surfaces and upwardly curved adjacent said arm front ends to reduce snagging tendencies during sliding along a surface.
