Abstract

571,863. Doors and door frames. MILLS. F. Nov. 12, 1943, No. 18913. [Class 51 (ii)] The door and door frame of a melting or reheating furnace are arranged at an angle to the vertical and means are provided on the door, jambs and headframe to reduce friction when the door is being raised and lowered and to provide effective sealing. The headframe 1 consisting of a flat plate is provided with flanges 7 secured to buckstaves 5 to which are also secured the flanges 8 of the door jambs. The headframe and jambs are provided with ribs 7A and 9 of semicircular cross-section which engage with corresponding recesses in the side flanges 12 of the door 10. The semicircular recesses in the door flanges are of larger radius than the ribs 7A, 9 to reduce friction. The door rests on an inclined sill 3A and the bottoms of the door flanges may be chamfered to engage chamfered lugs on the sill. The lifting gear for the door may be so arranged that when the door is first lifted from its closed position the upper part is moved slightly outwards. The headframe and jambs may be provided with recesses to engage with ribs on the door.
