Abstract

Disclosed are means for pivoting and positioning the bobbin tube grasper bars of an automatic doffing apparatus with precision and in concert on both sides of a textile yarn processing machine, such as a spinning frame, such that tube grasper elements depending from said bars are precisely positionable in coaxial alignment with and above the spindle blades thereof for donning tubes thereon by gravitational free fall. Present means obviate the problems associated with a non-linear or otherwise skewed grasper bar due to an imbalance of diverse forces imposed at diverse points along the longitudinal length thereof, as frequently occurs in prior art constructions. Present means employs a single actuating means, such as a hydraulic piston and cylinder assembly, joined by linkages to move control shafts on both sides of the machine, the control shafts in turn being interconnected with each grasper bar lifting and pivoting mechanism spaced therealong by a bell crank and pivot lever. Further present means includes adjusting means for balancing all forces exerted on the grasper bar and adjusting its aforesaid position exactly by changing the pivot point position of each bell crank.
