Abstract

A means for guiding a coke oven door as it is replaced on an oven. The guide means includes bars carried by the door frame for guiding the door accurately to a position in which the sealing members contact a flat surface on the jamb to effect a seal. The forward tips of the guide bars are closely adjacent the forward edges of the sealing members so that the guide bars serve also as stops to prevent overloading of the sealing members.

Claims

1. In a coke oven door which includes a metal frame, latch bars rotatably mounted on said frame for latching the door in its closed position, and flexible metal sealing members extending around the perimeter of said frame and having forward edges adapted to contact a flat surface for effecting a seal, the combination therewith of improved means for guiding said door, said means comprising a plurality of guide bars affixed to said frame in line with the latch bars when the latch bars are in a position for latching the door in its closed position, said guide bars having forward end portions which taper at their outside faces toward their forward tips, the forward tips of said guide bars being closely adjacent the forward edges of said sealing members to enable said guide bars to contact said flat surface after the sealing members and serve also as stops.

2. A combination as defined in claim 1 in which said guide bars are supported for adjustment on said frame.

3. A combination as defined in claim 1 in which the spacing between the forward edges of said sealing members and the tips of said guide bars in a direction normal to the flat surface in the unlatched position of the door is in the range of about 1/16 to 3/16 inch.

4. A combination as defined in claim 1 in which the forward tips of said guide bars are rounded.

5. In a coke oven which includes a door, a jamb for receiving said door, and cooperating latch bars on said door and latch hooks on said jamb for latching the door to the jamb, said door having a metal frame and flexible metal sealing members extending around the perimeter of said frame, said jamb having a flat surface to be contacted by the forward edges of said sealing members to effect a seal, the combination therewith of:

a plurality of guide bars carried by said frame, and located in line with the ends of said latch bars when the latter are engaged with said latch hooks;

said guide bars having forward end portions which taper at their outside faces toward their forward tips and said latch hooks having rearward end portions which taper at their inside faces away from said jamb to guide the door accurately to a position in which the forward edges of said sealing members contact said flat surfaces;

the forward tips of said guide bars being closely adjacent the forward edges of said sealing members to enable said guide bars to contact said flat surfaces after said sealing members and serve also as stops.

6. A combination as defined in claim 5 in which said guide bars are supported for adjustment on said frame.

7. A combination as defined in claim 5 in which the spacing between the forward edges of said sealing members and the tips of said guide bars in a direction normal to the flat surface in the unlatched position of the door is in the range of about 1/16 to 3/16 inch.

8. A combination as defined in claim 5 in which the forward tips of said guide bars are rounded.
