Abstract
Abstract A row crop harvester, such as a corn head, has a plurality of forwardly extending gathering members adapted to move between adjacent rows of row planted crops as the harvester advances, and each gathering member includes a hood-like downwardly and forwardly inclined shield structure having forwardly converging sides tapered to a forward gathering point. Removably mounted on top of the shield structure is a shield extension or ear saver that includes an upright inverted U-shaped support, the opposite ends of which are receivable in upright sockets on the opposite sides of the shield structure, a rear panel coplaner with the support and closing the interior thereof, the rear panel having a lower edge abutting the top of the shield structure, and a front panel that is generally semiconical in shape and extends forwardly and downwardly from the support, the apex of the front panel abutting the top of the shield structure. A quickly releasable latch is provided between the top of the shield structure and the front panel adjacent the apex, so that the shield extension can be quickly removed by releasing the latch and lifting the support and the front and rear panels attached thereto upwardly from the shield structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
168 words
In a multi-row crop harvester having at least one forwardly extending gathering member adapted to move between a pair of adjacent rows of row planted crops as the harvester advances and including a hood-like downwardly and forwardly inclined shield structure on top of the gathering member with opposite forwardly converging sides, the combination therewith of an improved shield extension mounted on the shield structure and comprising: an inverted generally U-shaped support having opposite generally upright legs and a transversely extending bight portion; a pair of laterally spaced attachment means on the shield structure respectively adapted to removably mount the lower ends of the support legs on the shield structure; a front panel member mounted on and extending downwardly and forwardly from the support and having a lower edge adjacent the top of the shield structure forwardly of the support; and latch means operative between the top of the shield structure and a lower, forward portion of the front panel for releasably locking the panel to the shield structure.
Claim 2
Dependent Claim
168 words
In a multi-row crop harvester having at least one forwardly extending gathering member adapted to move between a pair of adjacent rows of row planted crops as the harvester advances and including a hood-like downwardly and forwardly inclined shield structure on top of the gathering member with opposite forwardly converging sides, the combination therewith of an improved shield extension mounted on the shield structure and comprising: an inverted generally U-shaped support having opposite generally upright legs and a transversely extending bight portion; a pair of laterally spaced attachment means on the shield structure respectively adapted to removably mount the lower ends of the support legs on the shield structure; a front panel member mounted on and extending downwardly and forwardly from the support and having a lower edge adjacent the top of the shield structure forwardly of the support; and latch means operative between the top of the shield structure and a lower, forward portion of the front panel for releasably locking the panel to the shield structure.
Claim 3
Dependent Claim
30 words
The invention defined in claim 1 wherein the front panel tapers downwardly and forwardly from the support toward an apex that abuts the top of the shield structure centrally thereof.
Claim 4
Dependent Claim
91 words
The invention defined in claim 2 wherein the latch means includes a projection extending upwardly, from the shield structure, an aperture in the front panel adjacent said apex and adapted to receive the projection when the shield extendion is installed on the shield structure, and a removable latch element removably mounted on the projection above said aperture, the latch element preventing the upward movement of the front panel away from said projection when the front panel aperture is positioned on the projection and the latch element is mounted on the projection.
Claim 5
Dependent Claim
36 words
The invention defined in claim 2 wherein the front panel is generally semi-conical, the base of the cone being connected to the support and the vertex of the cone forming the apex of the front panel.
Claim 6
Dependent Claim
39 words
The invention defined in claim 1 and including a generally upright rear panel mounted on the support in generally the same plane therewith and having a lower edge abutting the shield structure when the shield extension is mounted thereon.
Claim 7
Dependent Claim
59 words
The invention defined in claim 1 wherein each attachment means comprises an upright socket means adjacent one side of the shield structure and adapted to receive the lower end of one of the support legs to restrain fore and aft or lateral movement of the support leg while permitting free upward withdrawal of the support from the socket means.
Claim 8
Dependent Claim
38 words
The invention defined in claim 1 and including pivot means swingably mounting the front panel on the bight portion of the support for permitting swinging movement of the front panel on the support about a horizontal transverse pivot.
Claim 9
Dependent Claim
42 words
The invention defined in claim 7 and including a generally upright rear panel mounted on the support in generally the same plane therewith and having a lower edge abutting the top of the shield structure when the shield extension is mounted thereon.
Claim 10
Dependent Claim
233 words
In a multi-row crop harvester having at least one forwardly extending gathering member adapted to move between a pair of adjacent rows of row planted crops as the harvester advances and including a hood-like downwardly and forwardly inclined shield structure on top of the gathering member with opposite forwardly converging sides, the combination therewith of an improved shield extension mounted on the shield structure and comprising: a support including a pair of generally upright legs; a pair of upright socket means adjacent the opposite sides of the shield structure and adapted to receive the lower ends of the support legs to restrain fore and aft or lateral movement of the support legs while permitting free upward withdrawal of the support from the socket means; a front panel member mounted on and extending forwardly from the support, said front panel tapering downwardly and forwardly from the support toward an apex that abuts the top of a shield structure forwardly of the support and having a lower edge adjacent the top of the shield structure; a generally upright rear panel mounted on the support rearwardly of the front panel and having a lower edge abutting the top of the shield structure when the shield extension is mounted thereon; and latch means operative between the top of the shield structure and the front panel adjacent said apex for releasably locking the panel to the shield structure.
Claim 11
Dependent Claim
233 words
In a multi-row crop harvester having at least one forwardly extending gathering member adapted to move between a pair of adjacent rows of row planted crops as the harvester advances and including a hood-like downwardly and forwardly inclined shield structure on top of the gathering member with opposite forwardly converging sides, the combination therewith of an improved shield extension mounted on the shield structure and comprising: a support including a pair of generally upright legs; a pair of upright socket means adjacent the opposite sides of the shield structure and adapted to receive the lower ends of the support legs to restrain fore and aft or lateral movement of the support legs while permitting free upward withdrawal of the support from the socket means; a front panel member mounted on and extending forwardly from the support, said front panel tapering downwardly and forwardly from the support toward an apex that abuts the top of a shield structure forwardly of the support and having a lower edge adjacent the top of the shield structure; a generally upright rear panel mounted on the support rearwardly of the front panel and having a lower edge abutting the top of the shield structure when the shield extension is mounted thereon; and latch means operative between the top of the shield structure and the front panel adjacent said apex for releasably locking the panel to the shield structure.
