Abstract:

An improved grinding machine loader assembly includes a rotatable wheel upon which a plurality of workpiece supports are mounted at equally spaced apart locations. After a latch member has been moved into engagement with the wheel and a locking member has been disengaged from the wheel, an index motor is operated through a loading stroke to pivot an index arm on which the latch member is disposed. This pivotal movement of the index arm and latch member rotates the wheel through an arcuate distance equal to the distance between the workpiece supports. As the wheel rotates, a workpiece on one of the supports is moved into a work area where it is engaged by the headstock and footstock of the grinding machine. The locking member is then moved back into engagement with the wheel and the latch member is disengaged from the wheel. After the latch member has been disengaged, the index motor is operated through a return stroke without moving the wheel.
