Dipper Stick with Implement Coupling Means

A front end assembly for a machine having a main frame, a boom pivotally connected to said main frame and means for pivoting said boom relative to said frame, comprising:

• a dipper stick pivotally connectable to said boom;
• a pair of support links pivotally connected to said dipper stick and having a connecting pin mounted on free ends thereof;
• means operatively interconnecting said dipper stick and said connecting pin for pivoting said support links;
• at least two implements each having a pair of mounting pins;
• a first assembly including a pair of jaw members pivotally connected to said dipper stick and cooperable upon pivotal movement thereof to selectively grip and release one of said mounting pins of a selected one of said implements, and means for selectively pivoting said jaw members in opposite directions to effect such grip and release of said one of said mounting pins;
• and
• second and third assemblies each including a pair of jaw members pivotally connected to one of said tilt links and cooperable upon pivotal movement thereof to selectively grip and release the other of said mounting pins of said selected one of said implements, and means for selectively pivoting said jaw members in opposite directions to effect said grip and release of said other of said mounting pins.
