Concave latch mechanism for an agricultural combine
First Claim
1. A concave latch mechanism for an agricultural combine comprising:
- a. a curved frame having a support slot and a handle support;
b. a concave having an adjust pin and a concave pin, said concave and said frame surrounding a rotor;
said adjust pin inserted into the support slot; and
c. a hinge housing attached to the handle support, said housing having a curved cradle plate with an aperture, therein, said plate capable of receiving the concave pin, wherein the curved frame, the concave and the rotor are parallel to a flow of grain, wherein the hinge housing further comprises;
i. a lever with a handle grip said lever attached to the hinge housing;
ii. a frame attachment affixed to the hinge housing;
iii a handle hinge affixed to the lever;
iv an attachment hinge affixed to the frame attachment; and
v a handle pin inserted between the attachment hinge and handle hinge, whereby the handle hinge rotates about the attachment hinge.

Abstract
The disclosure relates to a concave latch mechanism for an agricultural combine. The invention consists of concave surrounding a rotor. The concave has a concave pin and an adjust pin. The adjust pin is inserted into a support slot located in the frame. The concave pin is inserted into a handle also located on the frame. The handle has a lever which orients a curved cradle plate which supports the concave pin. When the lever is released, the cradle plate correctly orients the concave pin with the handle. The concave pin enters the cradle plate through an aperture. The aperture can have a sloped lead-in which assists in the positioning of the concave pin. The handle can also have an isolation mount between a portion of the handle and the frame. This isolation mount helps minimize vibrational noise from the rotor.
