Abstract
Abstract A pair of superposed parallel crop conditioner rolls, one journaled in a frame on a fixed axis, the other mounted for generally upward and downward movements toward and away from the one roll. Springs yieldingly urge the moveable roll towards the fixedly positioned roll, and stop elements limit movement of the moveable roll toward the fixedly positioned roll. Adjustment mechanism positions the moveable roll generally forwardly or rearwardly relative to a position vertically spaced from the axis of the fixedly positioned roll.

Claim 1
Independent Claim
221 words
In a mower and hay conditioner structure: a. a mobile frame including an elongated transverse frame member and a pair of end frame members spaced apart longitudinally of said transverse frame member and extending generally parallel to the direction of travel of the frame; b. a pair of parallel upper and lower conditioner rolls having opposite ends disposed adjacent said end frame members, one of said rolls being journaled in said end frame members on a generally horizontal axis; c. means mounting the other of said rolls for rotation with said one of the rolls and for movements in opposite directions toward and away from said one of the rolls and including a pair of crank arms; d. arm mounting means pivotally mounting said crank arms on said end frames on axes parallel to the axes of said rolls; e. and means limiting pivotal movements of said arms in the direction of movement of said other roll toward said one of the rolls and including; 1. a pair of abutment members each mounted on a different one of said arms; 2. and a pair of pads each mounted on said frame in the path of movement of a different one of said abutment members, said pads including elastic portions disposed to cushion the impact of said abutment members against said pads.

Claim 3
Dependent Claim
37 words
The mower and conditioner structure defined in claim 1, characterized by yielding means secured to said arms and frame members and urging said other one of the rolls in a direction toward said one of the rolls.
Claim 4
Dependent Claim
40 words
and a pair of pads each mounted on said frame in the path of movement of a different one of said abutment members, said pads including elastic portions disposed to cushion the impact of said abutment members against said pads.
Claim 5
Dependent Claim
40 words
and a pair of pads each mounted on said frame in the path of movement of a different one of said abutment members, said pads including elastic portions disposed to cushion the impact of said abutment members against said pads.
Claim 6
Dependent Claim
82 words
The mower and conditioner structure defined in claim 2 in which said arm mounting means includes a pair of eccentric elements one for each of said crank arms, said eccentric elements being rotatable to move the axis of rotation of each crank arm in directions to impart movement to said other one of the rolls in generally forward and rearward directions tangentially of said one thereof, and locking meaNs for releasably locking said eccentric elements in desired set positions of rotation thereof.
Claim 7
Dependent Claim
75 words
The mower and conditioner structure defined in claim 3 in which said locking means includes a pair of radial arms each secured to a different one of said eccentric elements, a pair of locking arms each pivotally secured to said frame, and a locking connection between each radial arm and a different one of said locking arms and adjustably locking one of said radial and locking arms in set positions longitudinally of its respective arm.
Claim 8
Dependent Claim
54 words
The mower and conditioner structure defined in claim 3 in which said abutment members are mounted on their respective arms for limited pivotal movement on axes generally parallel to the axis of said other one of the rolls, characterized by means for releasably locking said abutment members in set positions of said pivotal movement.
Claim 9
Dependent Claim
53 words
The mower and conditioner structure defined in claim 3 in which said abutment members define flat faces for face-to-face engagement with said pads, each of said pads including at least one shim plate disposed in overlying face-to-face relationship with its respective elastic portion for engagement with a respective one of said abutment members.
Claim 10
Dependent Claim
80 words
The mower and hay conditioner structure defined in claim 1 in which said frame member includes a pair of longitudinally spaced generally vertical mounting plates facing rearwardly of the frame, said elastic pad portions each being disposed in face-to-face engagement with the rear surface of a different one of said mounting plates, said pads each including at least one metallic shim plate overlying its respective elastic portion, characterized by anchoring means for releasably holding said pads on said mounting plates.
Claim 11
Dependent Claim
72 words
The mower and conditioner structure defined in claim 7 in which said anchoring means comprises a pair of laterally spaced clamping members overlying spaced portions of each of said pads, each of said clamping members having opposite end portions projecting laterally outwardly of opposite edges of their respective pads, and nut-equipped anchoring studs projecting rearwardly from said mounting plates and projecting through openings in said opposite end portions of the clamping members.
