ABSTRACT:
A spring adjusting device for a self-sealing coke oven door embodies a plurality of elongated, outwardly projecting housings carried by the outer side of the door. Each housing is provided with an elongated passageway therethrough in alignment with an opening through the door adjacent the outer edge thereof. A plunger is mounted for sliding movement through each opening with one end of the plunger engaging a flexible sealing member carried by the door and urging a sealing edge of the sealing member into engagement with the door jamb upon inward movement of the plunger. A compression spring is mounted within the passageway with one end thereof engaging an adjacent end of the plunger. Guide members at each end of the spring retain the spring in alignment with the plunger and out of engagement with the passageway. An actuator carried by the outer end of the housing compresses the spring and urges the plunger toward the sealing member. A heat resistant sealing member provided between the actuator and the housing forms a labyrinth seal which prevents ingress of foreign material therebetween.
