Three Section Threshing Concave Configuration and Adjustment Mechanism for an Agricultural Harvesting Combine
First Claim
1. A rotor and cage assembly for a harvesting combine, which comprises:
- (a) a rotor having a longitudinal axis of rotation;
(b) a skeleton comprising curved spaced-apart side members affixed to laterally extending horizontal spaced-apart members therebetween with pivots where they connect, the skeleton surrounding the rotor, one of the curved spaced-apart horizontal members being terminated with curved fingers;
(c) 3 concave inserts insertable laterally into the skeleton spanning 270°
around the rotor, one of the concave inserts carrying straight fingers that interlace with the skeleton horizontal member curved fingers;
(d) a control assembly comprising;
plates having arcuate slots placed at 3 of the pivots of the skeleton assembly;
(ii) control bars connected to the skeleton pivots; and
(iii) an actuator connected to the control bars at one end for arcuate rotation of the control bars resulting in the synchronized rotation of the arcuate slotted plates so that the interlaced straight fingers move closer together or farther apart with the fixed skeleton assembly curved fingers for different types of grain; and
(e) a grate assembly following and adjacent to the concaves skeleton and surrounding the rotor.

Abstract
Disclosed is a rotor and cage assembly that includes a skeleton of curved spaced-apart side members affixed to laterally extending upper and lower spaced-apart members therebetween and surrounding the rotor. One of the curved spaced-apart side members is terminated with curved fingers. Three concave inserts insert laterally into the skeleton spanning 270° around the rotor. One of the concave inserts carries straight fingers that interlace between the skeleton side member curved fingers. A control assembly of plates having arcuate slots placed at 3 of the pivots of the skeleton assembly, control bars connected to the skeleton pivots, and an actuator connect to the control bars at one end effect arcuate rotation of the control bars resulting in the synchronized rotation of the arcuate slotted plates so that the interlaced straight fingers move closer together or farther apart with the fixed skeleton assembly curved fingers for different types of grain.

12. A concaves control assembly for a concaves assembly comprising:
-
(a) a skeleton for receiving at least two concave inserts end-to-end; (b) at least two concave inserts inserted within the skeleton for threshing grain in concert with a rotor assembly; (c) rotatable plates having arcuate slots, located where the at least two concave inserts meet, and carried by and rotatable with skeleton pivot pins; (d) control bars connected to and between the skeleton pivot pins; and (e) an actuator connected to the control bars at one end of one of the control bars, whereby actuation of the actuator moves the control bars causing arcuate rotation of the arcuate slotted plates for moving the at least two end-to-end concave inserts closer together and farther apart. - View Dependent Claims (13, 14, 15)
