Abstract
Abstract A crop pickup component of a farm implement is floatingly supported by a four point linkage and associated springs that are, in turn, coupled with a swingable gauge roller in such manner as to yieldably bias the latter toward the ground so that shocks are absorbed as the roller follows the ground contours while the crop is being gathered and loaded.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
In combination with a farm implement having a framework supporting a component of the implement for up-and-down movement toward and away from the ground, a shock absorbing assembly comprising: structure mounted on said component for up-and-down swinging movement relative to the latter; gauge means supported on said structure for movement along the surface of the ground during travel of said implement; and flotation means interconnecting said framework and said structure for swinging the latter in a direction yieldably biasing said gauge means toward the ground.
Claim 2
Dependent Claim
85 words
In combination with a farm implement having a framework supporting a component of the implement for up-and-down movement toward and away from the ground, a shock absorbing assembly comprising: structure mounted on said component for up-and-down swinging movement relative to the latter; gauge means supported on said structure for movement along the surface of the ground during travel of said implement; and flotation means interconnecting said framework and said structure for swinging the latter in a direction yieldably biasing said gauge means toward the ground.
Claim 3
Dependent Claim
21 words
In an assembly as claimed in claim 1; and stop means for limiting the extent of swinging movement of said structure.
Claim 4
Dependent Claim
14 words
In an assembly as claimed in claim 1 wherein said flotation means is resilient.
Claim 5
Dependent Claim
27 words
In an assembly as claimed in claim 1 wherein said gauge means is mounted oN said structure for rotation when moving over the surface of the ground.
Claim 6
Dependent Claim
32 words
In an assembly as claimed in claim 1 wherein said structure includes a pair of horizontally spaced arms swingable about aligned axes traversing the intended path of said travel of the implement.
Claim 7
Dependent Claim
37 words
In an assembly as claimed in claim 5; and flexible means at one end of each arm respectively coupling the same with said component for limiting the extent of swinging movement of the arms in one direction.
Claim 8
Dependent Claim
48 words
In an assembly as claimed in claim 5 wherein said gauge means spans the distance between the arms and is secured to the arms at one end of the latter for rotation when moving over the surface of the ground about an axis parallel with said aligned axes.
Claim 9
Dependent Claim
32 words
In an assembly as claimed in claim 7 wherein said flotation means includes a coil spring connected to each arm respectively at the opposite end thereof and extending upwardly from the arms.
Claim 10
Dependent Claim
37 words
In an assembly as claimed in claim 8 wherein said component is provided with a stop beneath said opposite end of each arm respectively for limiting the extent of swinging movement of the arms in one direction.
Claim 11
Dependent Claim
39 words
In an assembly as claimed in claim 9; and flexible means at said one end of each arm respectively coupling the same with said component for limiting the extent of swinging movement of the arms in the opposite direction.
