Abstract From the Canadian patent

A characteristic feature of the proposed pickup conveyer, comprising drive shafts, a conveyer belt carrying support elements held thereto, spring-actuated double pickup fingers provided with a yoke-shaped interspring crosspiece and made fast on said support elements resides in the fact that said support element is shaped as a channel iron between the flanges of which the spring-actuated double pickup finger is mounted, said flanges having holes for a U-shaped holder to fit, one of the ends of said holder being recurvate towards the ends of the pickup fingers. The present invention can be applied to best advantage for picking various farm crops both windrowed and spread.
