Abstract
A projectable device for aligning rail mounted equipment with track side structures, and, in particular, for aligning a coke oven door extractor, pusher ram, or jamb cleaner with a coke oven door. In one embodiment, a rod having an attached terminal fork is extended horizontally toward the door so as to indicate alignment when an attached aligning plate is engaged by the fork. The rod projects from a piston and cylinder combination, and it is automatically withdrawn if alignment is correct. In a second embodiment, an arm having an attached terminal fork is swung downwardly in a vertical arc to engage the aligning plate and thereafter automatically returned to its initial, vertical position, if alignment is correct.
