Abstract

Abstract A breakaway mechanism for a twine wrapping apparatus on a roll baling machine couples a twine dispensing member to a pinion which is in intermeshing engagement with a gear rack. The pinion and the gear rack cooperate to effect pivoting movement of the twine dispensing member. The breakaway mechanism permits the twine dispensing member to be uncoupled from the pinion when a predetermined load is exerted on the twine dispensing member during its pivoting movement.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 68 words
In a roll baling machine having a twine dispensing member, a pinion and a gear rack in intermeshing engagement for effecting pivoting movement of said twine dispensing member, the improvement comprising: mechanism coupling said twine dispensing member to said pinion while permitting said twine dispensing member to be uncoupled from said pinion when a predetermined load is exerted on said twine dispensing member during said pivoting movement thereof.
Claim 2
Dependent Claim 68 words
In a roll baling machine having a twine dispensing member, a pinion and a gear rack in intermeshing engagement for effecting pivoting movement of said twine dispensing member, the improvement comprising: mechanism coupling said twine dispensing member to said pinion while permitting said twine dispensing member to be uncoupled from said pinion when a predetermined load is exerted on said twine dispensing member during said pivoting movement thereof.
Claim 3
Dependent Claim 30 words
The improvement of claim 1, said mechanism comprising a plate secured to said twine dispensing member, said plate having projections formed thereon for engagement in grooves formed in said pinion.
Claim 4
Dependent Claim 18 words
The improvement of claim 2, said mechanism further comprising a spring for urging said projections into said grooves.
Claim 5
Dependent Claim 32 words
