Abstract
Abstract A series of spring-loaded row units are individually mounted on the header of a harvester by a hinge assembly on the cutter bar and by upper supports extending between the units and a rear frame piece of the header. The hinges have interlocking hooks which rock relatively as the row units swing up and down over uneven terrain, the hooks being of such nature as to permit relative sliding movement as the distances between the units are varied. The supports are releasably hooked at the frame piece so that the entire distance adjustment as well as unit removal and remounting may take place quickly and easily by a single operator with but a single tool to release a pair of fasteners on each unit. Adjustment of the tilt of the units is equally as rapid and easy because of the use of a hook-slot arrangement in each of the top-rear supports.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
In a row harvester, a header provided with a transverse cutter bar, an upper transverse frame piece disposed rearwardly of the cutter bAr, a series of row units along the cutter bar each provided with crop gathering and divider means, and structure for mounting said units on the cutter bar and on the frame piece, said structure comprising: a hinge assembly interconnecting said units and said cutter bar for up-and-down swinging movement of the units relative to the cutter bar; and an upper attachment including a support member extending rearwardly from the upper end of each unit respectively, and a coupling pivotally securing the members to said frame piece, each member having spring-loaded elements shiftable relatively in response to said swinging movement of its corresponding unit, said hinge assembly and said coupling each having interconnected parts shiftable relatively transversely of the header for varying the distances between the units, with said parts of the hinge assembly slidably interlocked during relative shifting thereof transversely of the header.
Claim 2
Dependent Claim
166 words
In a row harvester, a header provided with a transverse cutter bar, an upper transverse frame piece disposed rearwardly of the cutter bAr, a series of row units along the cutter bar each provided with crop gathering and divider means, and structure for mounting said units on the cutter bar and on the frame piece, said structure comprising: a hinge assembly interconnecting said units and said cutter bar for up-and-down swinging movement of the units relative to the cutter bar; and an upper attachment including a support member extending rearwardly from the upper end of each unit respectively, and a coupling pivotally securing the members to said frame piece, each member having spring-loaded elements shiftable relatively in response to said swinging movement of its corresponding unit, said hinge assembly and said coupling each having interconnected parts shiftable relatively transversely of the header for varying the distances between the units, with said parts of the hinge assembly slidably interlocked during relative shifting thereof transversely of the header.
Claim 3
Dependent Claim
25 words
