A coke oven door includes a mainframe, a diaphragm assembly coupled with the mainframe, and a plurality of load-exerting assemblies attached to the mainframe. The diaphragm assembly includes a pan and a sealing edge structure attached to the pan. The sealing edge structure includes a load-receiving surface, a door-sealing surface spaced from the load-receiving surface, and a plurality of scallops spaced from one another. Each of the load-exerting assemblies is positioned and configured to selectively, operably apply a load to the load-receiving surface of the sealing edge structure. The scallops are configured and positioned to facilitate deflection of the sealing edge structure, in response to loads applied to the load-receiving surface, such that the door-sealing surface is configured to be positioned in contacting, and at least substantially sealing, engagement with a door jamb of a coke oven body.

Coke oven assemblies, doors therefor, and methods

This invention relates to a roller mounting system for use in a table (10) for conveying articles of manufacture through a production line. The mounting system includes a split frame for supporting an electric motor (26) for powering a roller (22) defining a generally horizontal path of travel along an upper surface of the roller table. The frame includes a fixed lower portion (30) connected to a structural member (34) of the roller table and an upper portion (32) adapted for longitudinal and vertical movement relative to the lower portion. Lower portion (30) includes a movable block (72) slidably mounted to a lower mounting plate (42) for cooperating with a threaded operator (74) mounted in a threaded bore in a block (70) for shifting the upper portion between an operating and a retracted position, a pair of spaced runners (44) and a block (62) having a stop surface (92). Upper portion (32) includes a block (56) on a chamfered end of the frame, a block (58 ) on the motor end of the frame for locking the upper portion to the lower portion when the upper portion is in the operating position and a pair of spaced runners (40) for being supported by lower runners (44). Each upper runner (40) includes a riser (46) and each lower runner (44) includes a riser (48). When block (72) is operated to shift upper portion (32) sufficiently to clear the risers, a defective or inoperative roller can be moved from the operating position to a retracted position so that the roller can not damage the articles.
