Abstract
1,227,300. Operating coke oven doors. SIMON CARVES Ltd. 8 Sept., 1969 [20 Nov., 1968], No. 44322/69. Heading C5E. A coke oven door 10 having latch bars adapted to engage hooks on the door frame, and flexible diaphragms acting through a fluid medium to exert pressure forcing the bars against the hooks, has means for reducing this pressure when the door is lifted for removal. The means comprises a diaphragm 24 connected by pipes with the other diaphragms and mounted at the centre of the door and acting against a spring 29 arranged about a pin 26 which has a slot 27 which receives an arm (43) on a bar 41 of a lever system (37 ... 40), see Fig. 6 (not shown). The door lifting lug (35) is connected to the levers so that on raising the lug, which is permitted a small vertical movement relative to the door, the levers rotate the arm (43) about a horizontal axis to move the pin 26 and plate 25 outwards against the spring 29 and reduce pressure in the diaphragm 24 and so in the other diaphragms. The pressure in the diaphragm 24 may be adjusted by nuts 34.
