AUTOMATIC PANEL LOCKING ARRANGEMENT prevents the frame from being started if any of the gearing end panels are not in place.
DIFFERENTIAL MOTION
IMPROVED DIFFERENTIAL MOTION.
All the gears on the Jack Shaft revolve in the same direction as the shaft itself. This reduces considerably the work the cone belt has to do, saves power, and gives more accurate winding and evener and better work.
A1 (40 teeth) drives the Spindle Shafts and S1 (50 teeth) drives the Bobbin Shafts. The gears on the Spindle and Bobbin Shafts are alike, i. e., they have the same number of teeth.
As the cut shows the number of teeth in all the gears of the Differential, it will readily be seen that if Q and Q1 are held stationary, the speed of S1 will be retarded 1 rev. for every 5 revs. the Jack Shaft makes, and the spindles and bobbins will be running at the same speed, no winding taking place. Winding is produced by the bobbins running faster than the spindles, therefore Q, which is driven from the bottom cone through carrier gears, must revolve. Its speed changes as the bobbins increase in diameter, being governed by the position of the cone belt, which is shifted slightly as each layer is put on the bobbins.
