Abstract
Abstract A discharge chute for use on a window turner having a pickup mechanism for elevating a windrow of crop material off the ground and a cross conveyor for receiving the elevated windrow and conveying the windrow laterally of the direction of travel as disclosed wherein the discharge chute is provided with an adjustable discharge edge for the floor member of the discharge chute over which the windrow must pass before being deposited on the ground. The floor member of the discharge chute is provided with an edge plate member positionally movable with respect to the floor base member, the edge plate member being fixed into a selected position relative to the floor base member by clamping bolts. The discharge edge is preferably oriented such that the inner end thereof adjacent the cross conveyor is spaced slightly forwardly of the centerline of the cross conveyor, while the outer end of the discharge edge is spaced forwardly of the inner end to define an acute angular relationship between the discharge edge and the centerline of the cross conveyor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
In a machine for inverting and displacing windrows of crop material, said machine having a frame; a pick-up mechanism mounted on said frame to elevate a windrow of crop material lying on the ground in a first orientation along a first path with a dry side above a damp side; a cross conveyor to receive said elevated windrow of crop material and convey said elevated windrow to a discharge end aligned in a fore-and-aft direction substantially perpendicular to a transverse extending cross conveyor centerline; a discharge chute supported by said frame adjacent said discharge end and being operable to receive said elevated windrow from said cross conveyor and redirect the movement thereof into a forward direction for discharge off a forward discharge edge to the ground; and drive means for operatively powering said pickup mechanism and said cross conveyor, the improvement comprising: said discharge edge extending from an inner end adjacent said discharge end of said cross conveyor to an outer end laterally spaced outwardly from said inner end, said outer end being forward of said inner end such that said discharge edge of said discharge chute is oriented at an acute angle to said cross conveyor centerline.
Claim 2
Dependent Claim
198 words
In a machine for inverting and displacing windrows of crop material, said machine having a frame; a pick-up mechanism mounted on said frame to elevate a windrow of crop material lying on the ground in a first orientation along a first path with a dry side above a damp side; a cross conveyor to receive said elevated windrow of crop material and convey said elevated windrow to a discharge end aligned in a fore-and-aft direction substantially perpendicular to a transverse extending cross conveyor centerline; a discharge chute supported by said frame adjacent said discharge end and being operable to receive said elevated windrow from said cross conveyor and redirect the movement thereof into a forward direction for discharge off a forward discharge edge to the ground; and drive means for operatively powering said pickup mechanism and said cross conveyor, the improvement comprising: said discharge edge extending from an inner end adjacent said discharge end of said cross conveyor to an outer end laterally spaced outwardly from said inner end, said outer end being forward of said inner end such that said discharge edge of said discharge chute is oriented at an acute angle to said cross conveyor centerline.
Claim 3
Dependent Claim
21 words
The machine of claim 1 wherein said inner end of said discharge edge is positioned forwardly of said cross conveyor centerline.
Claim 4
Dependent Claim
45 words
The machine of claim 2 wherein said discharge edge is defined by an end plate member adjustably mounted to a floor base member of said discharge chute to permit the angular relationship between said discharge edge and said cross conveyor centerline to be selectively varied.
Claim 5
Dependent Claim
33 words
The machine of claim 3 wherein said plate member is pivotally mounted to said discharge chute and selectively locked into position by a clamping bolt interengaging said plate member and said discharge chute.
Claim 6
Dependent Claim
182 words
In a machine for inverting and displacing windrows of crop material, said machine having a frame; a pick-up mechanism mounted on said frame to elevate a windrow of crop material lying on the ground in a first orientation along a first path with a dry side above a damp side; a cross conveyor to receive said elevated windrow of crop material and convey said elevated windrow to a discharge end aligned in a fore-and-aft direction substantially perpendicular to a transverse extending cross conveyor centerline; a discharge chute supported by said frame adjacent said discharge end and being operable to receive said elevated windrow from said cross conveyor and redirect the movement thereof into a forward direction for discharge off a forward discharge edge to the ground; and drive means for operatively powering said pickup mechanism and said cross conveyor, the improvement comprising: said discharge edge being defined by an edge plate member adjustably mounted to a floor base member of said discharge chute to permit a selective positional adjustment of the orientation of said discharge edge relative to said cross conveyor centerline.
Claim 7
Dependent Claim
182 words
In a machine for inverting and displacing windrows of crop material, said machine having a frame; a pick-up mechanism mounted on said frame to elevate a windrow of crop material lying on the ground in a first orientation along a first path with a dry side above a damp side; a cross conveyor to receive said elevated windrow of crop material and convey said elevated windrow to a discharge end aligned in a fore-and-aft direction substantially perpendicular to a transverse extending cross conveyor centerline; a discharge chute supported by said frame adjacent said discharge end and being operable to receive said elevated windrow from said cross conveyor and redirect the movement thereof into a forward direction for discharge off a forward discharge edge to the ground; and drive means for operatively powering said pickup mechanism and said cross conveyor, the improvement comprising: said discharge edge being defined by an edge plate member adjustably mounted to a floor base member of said discharge chute to permit a selective positional adjustment of the orientation of said discharge edge relative to said cross conveyor centerline.
Claim 8
Dependent Claim
57 words
The machine of claim 5 wherein said discharge edge extends between an inner end adjacent said discharge end of said cross conveyor and an outer end spaced laterally outwardly from said inner end, said outer end being positioned forwardly of said inner end such that said discharge edge extends acutely angularly relative to said cross conveyor centerline.
Claim 9
Dependent Claim
35 words
The machine of claim 6 wherein said plate member is pivotally mounted to said discharge chute and selectively locked against said discharge chute by a clamping bolt interengaging said plate member and said discharge chute.
Claim 10
Dependent Claim
17 words
The machine of claim 7 wherein said inner end is positioned forwardly of said cross conveyor centerline.
