Abstract
Abstract A twine wrapping apparatus for a roll baling machine includes a shuttle member which carries a gear rack that intermeshes with a pinion connected to a twine dispensing member such as a twine tube. When the shuttle member is moved generally transversely of the roll baling machine, the pinion is rotated by the gear rack resulting in pivoting movement of the twine tube.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
118 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: a shuttle member movable generally transversely of said base frame in the space defined between said side walls; a twine dispensing member pivotably mounted on said base frame; and a gear rack carried on said shuttle member in intermeshing engagement with a pinion connected to said twine dispensing member, said gear rack and said pinion cooperating to cause pivoting movement of said twine dispensing member when said shuttle member is moved generally transversely of said base frame in the space defined between said side walls.
Claim 2
Dependent Claim
118 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: a shuttle member movable generally transversely of said base frame in the space defined between said side walls; a twine dispensing member pivotably mounted on said base frame; and a gear rack carried on said shuttle member in intermeshing engagement with a pinion connected to said twine dispensing member, said gear rack and said pinion cooperating to cause pivoting movement of said twine dispensing member when said shuttle member is moved generally transversely of said base frame in the space defined between said side walls.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1, wherein said twine dispensing member is pivotably movable between a rest position and a dispensing position.
Claim 4
Dependent Claim
61 words
The apparatus of claim 2, wherein said twine dispensing member is pivoted from said rest position to said dispensing position when said shuttle member is moved toward one of said side walls, and said twine dispensing member is pivoted from said dispensing position to said rest position when said shuttle member is moved toward the other one of said side walls.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3, further comprising actuating means including a linear actuator for moving said shuttle member transversely of said base frame in the space defined between said side walls, said linear actuator being selectively extendable and contractable.
Claim 6
Dependent Claim
41 words
The apparatus of claim 4, wherein said shuttle member is moved toward said one side wall when said linear actuator is extended, and wherein said shuttle member is moved toward said other one side wall when said linear actuator is contracted.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5, wherein said actuating means also includes a lever arm connected between said linear actuator and said shuttle member.
Claim 8
Dependent Claim
23 words
The apparatus of claim 6, wherein said linear actuator and said lever arm are located outside the space defined between said side walls.
Claim 9
Dependent Claim
82 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: a pinion rotatably mounted on said base frame; a twine dispensing member connected to said pinion; a shuttle member movable generally transversely of said base frame in the space defined between said side walls; and a gear rack carried on said shuttle member in intermeshing engagement with said pinion.
Claim 10
Dependent Claim
82 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: a pinion rotatably mounted on said base frame; a twine dispensing member connected to said pinion; a shuttle member movable generally transversely of said base frame in the space defined between said side walls; and a gear rack carried on said shuttle member in intermeshing engagement with said pinion.
Claim 11
Dependent Claim
33 words
The apparatus of claim 8, further comprising a support beam extending between and connected to said side walls, a shaft fixed to said support beam, and said pinion rotatably mounted on said shaft.
Claim 12
Dependent Claim
21 words
The apparatus of claim 9, wherein said twine dispensing member is fixed to a plate which is connected to said pinion.
Claim 13
Dependent Claim
24 words
The apparatus of claim 8, wherein said shuttle member is supported at its ends by rods which are slidably disposed in said side walls.
Claim 14
Dependent Claim
36 words
The apparatus of claim 11, further comprising actuating means connected to at least one of said rods to move said shuttle member generally transversely of said base frame in the space defined between said side walls.
Claim 15
Dependent Claim
27 words
The apparatus of claim 12, wherein said actuating means comprises a linear actuator connected to a lever arm which is connected to said at least one rod.
Claim 16
Dependent Claim
23 words
The apparatus of claim 13, wherein said linear actuator and said lever arm are located outside the space defined between said side walls.
Claim 17
Dependent Claim
96 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: first and second pinions rotatably mounted on said base frame; first and second twine dispensing members connected to said first and second pinions, respectively; a shuttle member movable generally transversely of said base frame in the space defined between said side walls; and first and second gear racks carried on said shuttle member in intermeshing engagement with said first and second pinions, respectively.
Claim 18
Dependent Claim
96 words
In a roll baling machine having a base frame with a pair of side walls arranged to define a space therebetween, an apparatus for wrapping a roll bale with twine, said apparatus comprising: first and second pinions rotatably mounted on said base frame; first and second twine dispensing members connected to said first and second pinions, respectively; a shuttle member movable generally transversely of said base frame in the space defined between said side walls; and first and second gear racks carried on said shuttle member in intermeshing engagement with said first and second pinions, respectively.
Claim 19
Dependent Claim
60 words
The apparatus of claim 15, wherein said first and second gear racks cooperate with said first and second pinions, respectively, to cause pivoting movement of said first and second twine dispensing members in opposite directions with respect to each other when said shuttle member is moved generally transversely of said base frame in the space defined between said side walls.
