Abstract
A quick-disconnect lug for transporting cartons along the conveyor of a cartoning machine. The lug includes a base member for attachment to studs extending from the endless chain of the conveyor. The base member preferably has a pair of slots or recesses extending upwardly from its bottom edge for receiving the studs. A latch member is pivotally attached to the base member and includes a hooked end that acts to firmly engage one of the studs in a slot to lock the lug onto the conveyor chain. A spring member on the latch arm keeps the hooked end in a normally closed position to retain the hooked stud in a locked position. The pivot point of the latch member is positioned between the lever end and the hooked end of the spring member. The lever end may be moved downwardly to pivot the hooked end of the spring member out of the recess to allow a stud to be engaged or disengaged from the recess during machine set-up or changeover. Lugs are reset quickly and without tools. The quick disconnect apparatus can be used to secure various devices onto chains with extending studs.
