Patent attributes
A material loading device with inbuilt stability for the materials and largely immune to operator error includes a loading frame and at least one first locking mechanism. The loading frame defines a receiving cavity with at least one opening. Opposing inner walls of the loading frame define a plurality of slots. The first locking mechanism, comprising guide rod and first locking portions, is disposed at the opening. The first guide rod is disposed outside the receiving cavity, the first locking portions are movably built into at least one sidewall of the loading frame. The first guide rod will drop by gravity to just outside the loading frame, causing the first locking portions to move and lock the plurality of slots. The first guide rod can also be lifted by a parallel surface, moving the first locking portions away to unlock the slots.
