Abstract
Abstract A round bale trailer includes a conveyor running the length thereof with a hay bale unrolling machine at the rear end. The unrolling machine includes a pointed spindle pivotal between a rearwardly extending loading and unrolling position and a forwardly extending engaging and disengaging position. Operation of the conveyor away from the machine disengages the bale from the spindle while operation in the opposite direction impales the bale on the spindle. A collar is mounted on the spindle and includes radially spaced apart hay-engaging teeth for rotating the bale when driven by a hydraulic motor.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A vehicle-mounted round-bale handling and unrolling machine comprising, a vehicle having a longitudinal axis parallel to the line of travel of said vehicle, a substantially horizontally extending nonrotatable spindle parallel to said vehicle longitudinal axis and adapted to penetrate a bale of hay along its longitudinal axis as said vehicle is moved towards a bale, hay-engaging means positioned radially outwardly of said spindle for engagement with said hay radially outwardly of its axial center for rotation about said spindle and its longitudinal axis, and power means connected to said hay-engaging means for rotating said hay-engaging means and a bale of hay on said spindle for dispensing said hay by unrolling it.
Claim 2
Dependent Claim
111 words
A vehicle-mounted round-bale handling and unrolling machine comprising, a vehicle having a longitudinal axis parallel to the line of travel of said vehicle, a substantially horizontally extending nonrotatable spindle parallel to said vehicle longitudinal axis and adapted to penetrate a bale of hay along its longitudinal axis as said vehicle is moved towards a bale, hay-engaging means positioned radially outwardly of said spindle for engagement with said hay radially outwardly of its axial center for rotation about said spindle and its longitudinal axis, and power means connected to said hay-engaging means for rotating said hay-engaging means and a bale of hay on said spindle for dispensing said hay by unrolling it.
Claim 3
Dependent Claim
55 words
The structure of claim 1 wherein said hay-engaging means is further defined as including a collar rotatably mounted on said spindle and a plurality of hay-engaging teeth being provided on said collar for engagement with the end of said round bale of hay to rotate it as said collar is rotated by said power means.
Claim 4
Dependent Claim
18 words
The structure of claim 2 wherein said teeth are elongated and extend in parallel relationship to said spindle.
Claim 5
Dependent Claim
48 words
The structure of claim 2 wherein said spindle is pointed on its outer free end and said teeth are pointed on their free ends and said teeth are substantially shorter in length than said spindle which extends the substantial length of a round bale along its axial center.
Claim 6
Dependent Claim
20 words
The structure of claim 1 wherein said spindle is mounted on an upstanding frame member mounted on a three-point hitch.
Claim 7
Dependent Claim
37 words
The structure of claim 2 wherein said power means includes a drive wheel connected to said collar opposite said spindle and said power means is connected to said drive wheel for rotating said collar and hay bale.
Claim 8
Dependent Claim
28 words
The structure of claim 6 wherein said drive wheel has a smaller diameter than said collar whereby said collar protects said drive wheel from becoming entangled in hay.
Claim 9
Dependent Claim
25 words
The structure of claim 7 wherein said drive means further includes a motor connected to said drive wheel for rotating said collar and hay bale.
Claim 10
Dependent Claim
99 words
The structure of claim 2 wherein said machine is mounted at one end of a hay vehicle having a conveyor means moving along its bed surface, said spindle being pivotable between a first position extending rearwardly for engagement with a bale of hay on the ground and a second position extending forwardly over said conveyor means on said bed for said conveyor means to engage said bale and remove it from said spindle as it moves parallel to and away from said spindle or to move said bale onto said spindle as said conveyor means moves towards said spindle.
Claim 11
Dependent Claim
93 words
A round bale vehicle having an unrolling machine comprising, a vehicle having a bale conveyor on its support bed, and a round bale unrolling machine positioned on said vehicle over said bed and conveyor and having a bale spindle pivotable between a first position extending rearwardly of said vehicle to a second position extending forwardly thereof over said conveyor in parallel relationship whereby operation of said conveyor towards said spindle moves a hay bale into engagement with said spindle and operation away from said spindle moves a hay bale off of said spindle.
Claim 12
Dependent Claim
93 words
A round bale vehicle having an unrolling machine comprising, a vehicle having a bale conveyor on its support bed, and a round bale unrolling machine positioned on said vehicle over said bed and conveyor and having a bale spindle pivotable between a first position extending rearwardly of said vehicle to a second position extending forwardly thereof over said conveyor in parallel relationship whereby operation of said conveyor towards said spindle moves a hay bale into engagement with said spindle and operation away from said spindle moves a hay bale off of said spindle.
Claim 13
Dependent Claim
61 words
The structure of claim 10 wherein said spindle includes hay-engaging means positioned radially outwardly of said spindle for engagement with said hay radially outwardly of its axial center and for rotation about the longitudinal axis of said spindle, and power means for rotating said hay-engaging means and a bale of hay on said spindle for dispensing said hay by unrolling it.
Claim 14
Dependent Claim
55 words
The structure of claim 11 wherein said hay-engaging means is further defined as including a collar rotatably mounted on said spindle and a plurality of hay-engaging teeth being provided on said collar for engagement with the end of said round bale of hay to rotate it as said spindle is rotated by said power means.
