To Set Vise Automatic.
First set eccentric screw 6 (Fig. 15) on inner end of stopping and starting lever connection rod 8 (Fig. 15) so as to take up all lost motion between it and the vertical starting lever. Then set the eccentric screw 7 (Fig. 15) on outer end of the connecting rod 8 so as to take up all lost motion between it and vise automatic stop lever 4 (Fig. 15). To do this, pull out the vise automatic stop lever 4 with your finger until the inside end bears firmly against the vise automatic stop rod 1, which, in turn, comes in contact with the vise automatic stop mold disk dog 3 (Fig. 15); then pull out the starting and stopping hand lever 2 (Fig. 15) until machine starts. At the time when the machine starts the eccentric screw 7 should touch the outer end of the vise automatic stop lever 4, then there would be no lost motion and the vise automatic would act as follows:

In case of a tight line (which would not allow the first elevator to drop into the vise far enough to force the vise automatic stop rod 1 down to allow the mold disk dog 3 to pass over the pawl 5 in the stop rod 1) the disk coming forward would force the mold disk dog 3 against the pawl 5 in stop rod 1 which, coming in contact with inner end of vise automatic stop lever 4, would force the outer end of stop lever against eccentric screw 7, which would cause the machine to be shut off the same as if it were done by pushing the hand lever in by hand.
If the vise automatic is set this way it will stop mold disk nearly 1-16 inch away from matrices, leaving the first elevator free to lift up and a matrix to be taken out. This not only prevents a squirt, but saves the ears of the matrices in many cases.
