  • the centers of the cam plate and the UNITED STATES PATENTS circular plate coincide with the longitudinal axis of the 3.7l Tephtz t t r r t r r shaft
  • the cam urface has a piral shape is self.
  • the present invention distinguishes itself from the hammer-blow type of oven door by the fact that after the seal has been positioned. the seal no longer rests against the shaft with the hook-shaped extension but, instead. the seal is held in place solely by the force of frictional contact between parts.
  • the seal adjusted during the assembling procedure, is matched to the constant thermal expansion curve of the coke oven door and to the frame enclosing the opening into the oven chamber. After the seal is positioned, it must remain in this position in order to insure a tight-sealing relation with the oven chamber.
  • Coke ovens have recently been developed with a chamber height lying with a range of heights of from 4 to almost 8 meters and this has been accompanied with a proportional increase in the pressure exerted by a coke oven door against the door frame of the oven.
  • the coke oven doors develop cracks and be come graphitized whereby manual cleaning cannot be completely replaced by fully automatic cleaning since there is the danger that localized contamination will result in the transfer of unusually high forces to the seal in certain regions of a particular door which would overcome the frictional forces developed by the bolts with hooked-shape ends holding the seal, thus causing the sea] to slip back away from the door frame.
  • a coke oven door having a peripheral seal defining an edge surface adapted to abut against a frame surrounding an opening leading into a coke oven chamber, of apparatus at spaced locations about the periphery of the door for positioning the edge surface of the seal relative to the door
  • a shaft including a threaded end for support by the door, a cam plate supported by the shaft for an abutting relation with the rear edge ofthe seal. the cam plate being carried by the shaft and designed to provide a self-locking feature with respect to rotation of the shaft to resist forces acting upon the edge surface of the seal, and a circular plate supported by the shaft outwardly of the cam for clamping the seal against the door.
  • the present invention additionally provides. in its preferred form, that the cam plate includes a cam surface generated from a spiral form with the center thereof lying along the longitudinal axis of the shaft carrying the cam plate.
  • the aforesaid apparatus for positioning the edge surface ofthe seal is provided at each of spaced-apart locations about the periphery of the door and that bolts with hooked ends are located therebetween to additionally hold the seal to the side walls of the door.
  • the ratio of the number of bolts with hooked ends to the number of shafts with cam plates and circular clamping plates must be generally determined in conformity with special local conditions which would, of course, include the actual size of the coke oven doorv
  • the shafts with the threaded ends are positioned and held by the door so that the circular clamping plates overlap the rear portion of the edge seal and thereby define a segment of constant size.
  • the clamping plates are held in place by developing a particularly selected torque applied between bolt heads formed on the extended ends of the shafts and nuts on the ends of the shafts.
  • the shafts remain in position according to their given setting because of the self-locking design of the cam plates.
  • FIG. 1 is a front elevational view of a coke oven door
  • FIG. 2 is a side view of the coke oven door shown in FIG. 1;
  • FIG. 3 is a sectional view taken along line llllll of FIG. 1;
  • FIGS. 4a and 4b are enlarged sectional views similar to FIG. 3 and illustrating a bolt with a hooked end to hold an edge seal at different positions;
  • FIGS. Su and 51 are enlarged sectional views similar to FIG. 3 and illustrating two different positions of an edge seal as determined by a cam plate and a clamping plate according to the present invention.

  • FIG. 6b is a plan view of the parts shown in FIGS. 4b and 5h.

  • FIG. 8 is a sectional view taken along line VIII-VIII of FIG. 7.
  • FIG. 3 there is illustrated an opening 9 surrounded by a door frame 10 for the opening leading into a coke oven chamber. not shown.
  • a coke oven door supports a peripheral seal II having an edge surface Ila which may have the form of a knife-edge. adapted to abut against the frame I0 and form a tight seal therewith.
  • the body of the coke oven door has a U-shaped cross section made up of a front plate I2, side walls I3 and upper and lower end walls I4. Distributed about the periphery of the door at spaced-apart locations are holes that extend through the walls 13 and [4. Some of these holes receive bolts with hook-shaped ends and other holes receive a shaft having a cam plate and a circular clamping plate according to the features of the present invention.
  • each of these bolts is made up of a shaft 15 having threads at one end and a hook 16 at the other end for holding the seal II by frictional contact in an abutting relation with the walls I3 and 14.
  • a nut 17 is located on the threaded end of the shaft I5 at the inside of the walls.
  • each shaft 18 has a threaded end 19 receiving a nut I7 to secure it at one side of the walls 13 or I4.
  • the shaft projects through a hole in the walls 13 or 14 from the inside of the door where the nut I7 is located to the outside of the door where a cam plate 26 is secured on the shaft.
  • the cam plate defines a cam surface which has the form of a spiral as clearly illustrated in FIG. 8.
  • a circular clamping plate 20 Located at the extended side of the cam plate 26 is a circular clamping plate 20 and at its extended side there is located a hexagonal bolt head 25.
  • the longitudinal axis and more specifically the rotational axis of the shaft 18 is denoted by the reference numeral 21 in FIGS. 7 and 8.
  • the centers of the cam plate 26 and the clamping plate 20 lie along the longitudinal axis 2] of the shaft.
  • a cam surface of the cam plate 26 is generated from a spiral form which begins to rise from its lowest point at surface area 22 and reaches its greatest height at surface area 23 with respect to the center of the cam and the longitudinal axis 21 of the shaft.
  • the cam plates which are located at the left side and the right side of the door have their cam surfaces generated to spiral in opposite directions in order to make it easier for a serviceman to make the necessary adjustments to set the knife-edge seal by always rotating each shaft [8 in the same direction irrespective of its location in the door.
  • the serviceman may simply rotate the clamping plates located in the left side wall and right side wall of the door in the same direction in order to bring the cam plates into contact with the seal.
  • the seal 11 is located such that its rear edge is resting on the shaft 15 at a given location about the periphery of the door.
  • FIG. 5a a similar condi tion occurs where the rear edge of the seal II contacts the lowest portion of the cam, that is, the cam surface area 22.
  • FIG. 60 After the seal is adjusted relative to the hook bolts, the back edge of the seal may no longer make contact with the shaft 15 as shown in FIG. 4b. In this event, the cam plate 26 is rotated so that the cam surface is brought into contact with the rear edge of the seal as shown in FIG. 5b. The relationship of parts in this respect is additionally illustrated in FIG. 6!).
  • the coke oven door is urged by springs 30 toward the frame 10 surrounding the opening 9.
  • the resilient force of these springs is applied directly to the front plate I2 and resisted by crossbeams 31 that are, in turn, carried by arms extending from the frame 10.
