But if the lever 62 were to be turneddown so that the pin 61 were to bebrought down to the center line, then thetumbler block turning also in the Scotchyoke would lie in a nearly horizontal posi-tion and the roller 59 would slide back andforth in it giving it (the tumbler block)no motion at all. Of course intermediatepositions would have a corresponding in-fluence. By raising the handle 62 thepivot 61 is moved in the opposite direc-tion. Thus a full control can be ob-tained over the movement of the chutes,and each chute can be controlled independ-ently of the other by its own handle 62. In case of a break or stoppage of theelevator or conveyor the chutes can be GEAR CASE OF THE
