carried by the turntable close to its periphery,
jigger -mechanism cooperating with the molds, 20
a tool-carrying lever pivotally supported for ver
tical movement above said turntable, power
mechanism for driving the turntable and having
a releasing clutch, means for engaging the
notches in the turntable and operatively con
nected with the clutch and actuated by said tool
carrying lever for effecting the disengagement of
said means from a notch in the turntable and
the simultaneous closing of said clutch, and
means on the tool-carrying lever and engageable 30
with the turntable for the centering of a tool
with respect to the mold on the opening of the
clutch and the engagement of the ?rst-named
means in the notch in said table.
