DEFINITION

Classification: 460/85

Straw walker:

(under subclass 79) Subject matter including a moving rack or a similar element which separates the grain and moves the straw, chaff and other material out the back of the thresher.

(1) Note. The device tosses and tumbles the straw and chaff and propels it to the rear. This aggressive motion separates threshed grain from the straw and chaff. The straw travels the full length of the rack and is discharged at the rear. The device consists of section of bars which are driven by means which gives an alternate lifting and dropping motion as the straw is "walked" toward the rear.
