Abstract
Abstract An improved Corn Ear Cutter reduces kernel damage through the use of a cushion in the form of a strip of cushioning material, preferably urethane having a hardness in the range from about 50 to 60 Shore A, which is removably installed on the stripper plates by channels which are mounted on the plates and receive the strips by sliding them into the channel. The strips support the ears of corn at the moment they are cut from the stalk and then propelled along the gap by lugs extending from gathering belts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
In a corn harvesting machine having spaced apart stripper plates along and between which ears of corn and stalks are driven through a gap between the plates and wherein knife rolls are disposed below the plates for cutting the ears from the stalks, the improvement comprising strips of yieldable material disposed on said plates along said gap and defining cushions on which said ears bear as they travel along said gap, and means attached to said plates for removably retaining said strips on said plates.
Claim 2
Dependent Claim
85 words
In a corn harvesting machine having spaced apart stripper plates along and between which ears of corn and stalks are driven through a gap between the plates and wherein knife rolls are disposed below the plates for cutting the ears from the stalks, the improvement comprising strips of yieldable material disposed on said plates along said gap and defining cushions on which said ears bear as they travel along said gap, and means attached to said plates for removably retaining said strips on said plates.
Claim 3
Dependent Claim
21 words
The improvement according to claim 1 wherein said strips have a hardness from about 50 to about 60 Shore A durometer.
Claim 4
Dependent Claim
13 words
The improvement according to claim 2 wherein said strips consist of urethane material.
Claim 5
Dependent Claim
31 words
The improvement according to claim 1 wherein the height of the strips above the plates is sufficient to increase the length of the shank of the ears by about said height.
Claim 6
Dependent Claim
120 words
In a corn harvesting machine having spaced apart stripper plates along and between which ears of corn and stalks are driven through a gap between the plates and wherein rolls are disposed below the plates which facilitate cutting the ears from the stalks, the improvement comprising strips of yieldable material disposed on said plates along said gap and defining cushions on which said ears bear as they travel along said gap, means attached to said plates for removably retaining said strips on said plates which comprise channels attached to said plates along said gaps, the width of said channels being narrower than the width of said strips so as to expose said strips for engagement with the ears of corn.
Claim 7
Dependent Claim
120 words
In a corn harvesting machine having spaced apart stripper plates along and between which ears of corn and stalks are driven through a gap between the plates and wherein rolls are disposed below the plates which facilitate cutting the ears from the stalks, the improvement comprising strips of yieldable material disposed on said plates along said gap and defining cushions on which said ears bear as they travel along said gap, means attached to said plates for removably retaining said strips on said plates which comprise channels attached to said plates along said gaps, the width of said channels being narrower than the width of said strips so as to expose said strips for engagement with the ears of corn.
Claim 8
Dependent Claim
72 words
The improvement according to claim 5 wherein said channels have outsides attached to said plates and tops extending from said outsides across the width of said channels, said channels having lips shorter than said outsides thereof which lips extend downward from said tops said strips having grooves along one of their sides which defines the width thereof, and said strips being removably received in said channels with said lips in said grooves.
Claim 9
Dependent Claim
46 words
The improvement according to claim 6 wherein said channels are curved at one end thereof, said one end being attached to the forward ends of said plates where said ears and stalks enter said harvester, said strips being retained by said channels in said curved ends.
Claim 10
Dependent Claim
44 words
The improvement according to claim 7 wherein said strips are curved away from each other along said forward ends of said plates with curvatures greater than the curvatures of said forward ends so as to taper away from said gap on said forward ends.
