Description: |
| Abstract:
I have found that the feeding mechanism usually employed in grain-threshing machines does not work satisfactorily in bean-threshers on account of the tendency of the bean-stalks, especially after remaining any length of time in the mow, to string and pass over the feeding mechanism in bunches. Another objection to the feeding mechanisms used in grain-threshing machines consists in the difficulty experienced in attempting to remove stone from the beanstalks just before they enter the cylinder. The present methods of harvesting beans result in quite a quantity of stones being clogged up with the beans, and frequently they get upon the table and over the feeding mechanism into the cylinder, damaging the cylinder and concave. To overcome these difficulties, I have devised a self-feeding mechanism in which the presence of stones of any size sufficient to do serious damage gives an audible signal, and the operator may then readily tip the feeding mechanism in such a way that the stone will pass off from the feeding mechanism onto the ground without entering the cylinder.
Claim:
In a threshing-machine, a feeding mechanism consisting in a shaking- pan having teeth formed thereon, a handle or lever and connections between such handle and shaking-pan whereby such pan may be swung upward and to the rear on its operating crank-shaft by the movement of such handle, mechanism for operating such crank-shaft and connections between such handle and mechanism whereby the operative connection between such crankshaft and mechanism may 8 be broken by the movement of such handle. |
