COUPLER FOR EXCAVATING MACHINES AND THE LIKE
First Claim
1. A coupler mountable on a dipper stick and tilt assembly of a machine, and detachably connectable to an implement having a pair of spaced, substantially parallel mounting pins, comprising:
- a body having means for pivotally connecting said body to said dipper stick, means for pivotally connecting said body to said tilt assembly wherein upon operation of said tilt assembly said body will be caused to pivot about said dipper stick, a fixed jaw portion having an opening for receiving one mounting pin of said implement and a pivotally connected jaw member having an opening for receiving the other of said mounting pins;
a stop latch pivotally connected to said body, having a first arm section biased in a first position obstructing said opening in said fixed jaw;
a latch cam pivotally connected to said body having a first arm section engageable with an arm section of said stop latch for pivoting said stop latch upon pivoting said latch cam;
a fluid actuated cylinder assembly having one of the cylinder and rod members thereof pivotally connected to a second arm section of said latch cam and the other of said cylinder and rod members pivotally connected to said pivotal jaw for pivotal movement of said pivotal jaw upon displacements of said cylinder assembly; and
means cooperable with said cylinder assembly and said latch cam, functional to preclude pivotal movement of said latch cam when said body is disposed in a first orientation, and to permit pivotal movement of said latch cam when said body is disposed in a second orientation.

Abstract
A coupler mountable on the dipper stick and tilt assembly of a machine including a body provided with a fixed jaw and a pivotal jaw connectable to the mounting pins of an implement; a stop latch pivotally connected to the body, biased in a first position obstructing the removal of a mounting pin disposed in the fixed jaw; a latch cain pivotally connected to the body engageable with the stop latch for pivoting the stop latch upon pivoting the latch cam; a fluid actuated cylinder assembly operative interconnecting the latch cam and the pivotal jaw; and means of cooperable with the cylinder assembly and the latch cam, functional to preclude pivotal movement of the latch cam when the body is disposed in a first orientation, and to permit pivotal movement of the latch cam when the body is disposed in a second orientation.
