UNIVERSAL EJECTOR
The universal ejector consists of a series of blades, 5-points in thickness, in 2-em units; as a rule the first, or lower blade is a 4-em, and then in 2-em units up to 30-ems pica. These unit blades move between plates, which brace them firmly on both sides, making them rigid and preventing the blade from bending.
The back end of the unit blades are fastened to ejector blade links that move in grooves cut lengthwise of the slide. There is a link for each unit blade and they terminate at the back end of the mold slide in front of a groove milled across the slide. A movable controller bar works in a groove in the ejector slide, moving up or down in the groove, back of a lug on each of the blade links. When the ejector lever forces the ejector slide forward, the controller bar in the groove of the slide comes against the lugs of the ejector links forcing the blades forward through the mold.
The blades are withdrawn by a lug on the ejector slide coming in contact with the lugs on the links.
When desiring to change the length of the blade to be used, move the ejector blade controlling lever handle up or down. This handle is situated below the starting and stopping lever and is connected to the controller bar by a screw link. Also connected to this handle is a pica gauge which operates in a groove in the delivery channel.
Moving the handle up or down engages less or more blades, the length being indicated on the pica gauge in the delivery channel.
To remove the mold slide on machines which have a universal ejector, lower the vise to second position, set the ejector at 10 or 12 ems, take out the ejector blade controller link which screws into the controller link lift. This will permit the controller bar to drop out. Disconnect the mold slide and take out the ejector lever link. If the machine is connected up with the water for cooling the molds, it will be necessary to disconnect the hose before taking out the slide.
