Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A round bale forming machine for picking up cut hay from a field and forming it into a cylindrical bale, said baler comprising: portable frame means having a forward end and a rearward end; upright spaced side walls mounted on said frame; drum means rotatably mounted on said frame means between said side walls proximate said rearward end, said drum means having pickup means mounted on the periphery thereof for picking up the hay and for rolling the hay into a cylindrical bale and for forming the bale; roller means disposed forwardly of and parallel to said drum means and rotatably and movably mounted between said side walls for compacting, forming and rolling the bale; and power means connected to said drum to rotate same such that the portion thereof adjacent the ground moves forwardly in the same direction as the baler is moving of the baler with the peripheral speed of said roller substantially equal to the forward speed of the baler.
Claim 2
Dependent Claim
163 words
A round bale forming machine for picking up cut hay from a field and forming it into a cylindrical bale, said baler comprising: portable frame means having a forward end and a rearward end; upright spaced side walls mounted on said frame; drum means rotatably mounted on said frame means between said side walls proximate said rearward end, said drum means having pickup means mounted on the periphery thereof for picking up the hay and for rolling the hay into a cylindrical bale and for forming the bale; roller means disposed forwardly of and parallel to said drum means and rotatably and movably mounted between said side walls for compacting, forming and rolling the bale; and power means connected to said drum to rotate same such that the portion thereof adjacent the ground moves forwardly in the same direction as the baler is moving of the baler with the peripheral speed of said roller substantially equal to the forward speed of the baler.
Claim 3
Dependent Claim
151 words
A round bale forming machine as defined in claim 1 wherein said frame means includes a pair of spaced lifting arms pivotally secured thereto and depending therefrom; said drum means includes an axle interconnected between said lifting arms proximate the lower ends thereof and a drum rotatably mounted on said axle; and said roller means includes a pair of spaced elongated members, each pivotally secured proximate one end thereof to said lifting arms and projecting forwardly of said drum, a roller axle interconnected between the other ends of said spaced members, a roller rotatably mounted on said roller axle, wherein as a bale forms, said roller moves from a first position disposed generally forward of said drum through an arc to a second position disposed generally above said drum, and stop means coacting between said arms and said members to prevent said drum from contacting the ground in said first position.
Claim 4
Dependent Claim
50 words
A round bale forming machine as defined in claim 2 and including a comb means secured between said members and projecting rearwardly of said drum, said comb means provided to pick up hay missed by said drum and hold it proximate said drum wherein said drum picks up said hay.
Claim 5
Dependent Claim
63 words
A round bale forming machine as defined in claim 3 wherein said comb means includes a pair of rearwardly projecting spaced bars, each said bar secured on one end to one of said members, a transverse beam secured between the other end of said bars, and a plurality of spaced depending teeth secured to said transverse beam for sweeping hay from the ground.
Claim 6
Dependent Claim
26 words
A round bale forming machine as defined in claim 4 and including windrowing means rotatably mounted on said frame means for sweeping hay into a windrow.
Claim 7
Dependent Claim
31 words
A round bale forming machine as defined in claim 3 and including adjustable stop means secured to said frame means proximate said members for limiting the pivotal movement of said members.
Claim 8
Dependent Claim
102 words
A round bale forming machine as defined in claim 6 and including a band and spring means interconnected between said roller and said frame means forward end; said band and spring means including a rod interconnected between the ends of said members forwardly of said roller, a generally horizontally disposed tube rotatably mounted between said side walls proximate said frame means forward end, a plurality of elongated spaced bands having one end of each secured to said rod and having the other end wrapped around said tube; and a spring operably connected to said tube to bias said bands on said tube.
Claim 9
Dependent Claim
35 words
A round bale forming machine as defined in claim 7 and including a hydraulic means interconnected between said frame means and said lifting arms, said hydraulic means operable to raise and lower said lifting arms.
Claim 10
Dependent Claim
53 words
A round bale forming machine as defined in claim 8 and said roller has a plurality of teeth mounted on the periphery thereof to engage the bale, and said power means is generally connected to said roller to provide some with substantially the same peripheral speed as the peripheral speed of said drum.
