Abstract
A latching and locking mechanism for a door includes a locating pin passing through a portion of a door frame and a handle. A tapered portion formed at an end of the locating pin mates with a tapered opening formed in a casing of the machine to position the door frame relative to the casing. A cam surface defined on the casing engages a latching pin connected to the locating pin and extending radially therefrom adjacent to the tapered portion such that the latching pin pulls the door frame toward the closed position when the handle is rotated.
