Abstract
Abstract A machine for forming round bales of hay including a frame detachably connected to a three point hitch on a tractor and rearwardly extending arms are pivoted between an operational lower position to a raised upper position by a hydraulic cylinder such that a continuous flexible pickup chain extending over triangularly disposed rollers carried on the side members will be moved out of contact with the formed bale of hay when the side members are pivoted to the raised position. The continuous pickup member operates continuously in both the raised and lowered positions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
237 words
A tractor having a three-point hitch and hay baling machine for forming round bales comprising, said baling machine having a frame pivotally supported by and connected to said hitch, said frame including oppositely disposed side members, power means for operating said hitch to raise and lower said baling machine, a power cylinder connected at its forward end to said hitch and at its rear end to said baling machine frame remotely of said hitch connection to said baling machine frame for pivoting said baling machine up and down between a raised bale discharge position and a lowered bale forming position, and said baling machine including on said frame a powered continuous flexible hay rolling member extending around a plurality of spaced apart rollers extending between said side members and including a first roller spaced adjacent said hitch and above a second roller positioned adjacent the ground in said bale forming position when hay is being rolled into a bale, and a third roller disposed between and out of the plane of said first and second rollers, said third roller carried on an arm being spring biased to maintain said continuous flexible hay rolling member tight over a hay bale and bias said third roller on said arm to pivot towards the plane of said first and second rollers as said round bale is being formed, said first and second rollers always being stationary relative to each other.
Claim 2
Dependent Claim
237 words
A tractor having a three-point hitch and hay baling machine for forming round bales comprising, said baling machine having a frame pivotally supported by and connected to said hitch, said frame including oppositely disposed side members, power means for operating said hitch to raise and lower said baling machine, a power cylinder connected at its forward end to said hitch and at its rear end to said baling machine frame remotely of said hitch connection to said baling machine frame for pivoting said baling machine up and down between a raised bale discharge position and a lowered bale forming position, and said baling machine including on said frame a powered continuous flexible hay rolling member extending around a plurality of spaced apart rollers extending between said side members and including a first roller spaced adjacent said hitch and above a second roller positioned adjacent the ground in said bale forming position when hay is being rolled into a bale, and a third roller disposed between and out of the plane of said first and second rollers, said third roller carried on an arm being spring biased to maintain said continuous flexible hay rolling member tight over a hay bale and bias said third roller on said arm to pivot towards the plane of said first and second rollers as said round bale is being formed, said first and second rollers always being stationary relative to each other.
Claim 3
Dependent Claim
29 words
The structure of claim 1 wherein said powered continuous flexible hay rolling member is continuously operated during pivotal movement between said bale forming position and said bale discharge position.
Claim 4
Dependent Claim
36 words
The structure of claim 2 wherein said hitch and frame include an upstanding post to which said forward end of said power cylinder is secured and said power cylinder extends rearwardly over said continuous flexible member.
Claim 5
Dependent Claim
44 words
The structure of claim 2 wherein the powered continuous flexible hay rolling member is adapted to be powered by the power take-off on the prime mover and the speed of said continuous member is directly related to the forward speed of said prime mover.
Claim 6
Dependent Claim
71 words
The structure of claim 1 wherein said third roller is located relative to said first and second rollers such that as said bale of hay being formed becomes larger said continuous flexible member between said first and said second rollers is deflected towards said third roller which is beiNg simultaneously moved towards the plane of said first and said second rollers to compensate for the size of the bale of hay.
Claim 7
Dependent Claim
28 words
The structure of claim 5 wherein said first, second and third rollers are substantially arranged in triangular relationship before and during the formation of a bale of hay.
Claim 8
Dependent Claim
18 words
The structure of claim 9 wherein said oppositely disposed side members include runners for engagement with the ground.
Claim 9
Dependent Claim
26 words
The structure of claim 1 wherein the axis of pivotal movement of said side members is coincident to the axis of rotation of said first roller.
