Koppers Company, Inc.

Carl G Lindgren

A car for charging a coke oven battery with coal. This car carries a plurality of integral coal hoppers. A particular space frame construction is disclosed to support these hoppers, and because of this construction a significant savings in the weight of the car is realized. This space frame includes a pair of horizontally spaced lower front and rear parallel transverse beams and upper front and rear parallel transverse beams. Longitudinally extending beams connect both ends of the upper and lower front transverse beams with the corresponding rear transverse beams. The above described structure is mounted on four wheel housings by means of four truss structures. Two of these wheel housings are positioned slightly in front of the front transverse beams and two are mounted slightly behind the front transverse beams. Each of the front wheel housings is connected to the front transverse beams by means of one of the truss structures, and each of the rear wheel housings is connected to the rear transverse beams by one of the truss structures.

Coke oven charging car

A device for adjusting the position of a track mounted car from a first position where the car is initially spotted by conventional braking means to a second predetermined position on the track which must be reached within close tolerances. An arm which may be pivoted in a vertical arc parallel to the track is pivotally attached to the car at its one end and at its other end it has preferably cone-shaped feeler means which engages a protrusion fixed adjacent to the track. A preferably vertical gravity based reference position is selected for the arm, and a sensing means for producting a direct current output signal proportional in magnitude to angular displacement of the arm from this position and corresponding in polarity to direction of displacement is provided. This signal is inputed to a control means for a dual directional, variable speed hydraulic traction drive means for the car so it will move in the direction of its predetermined final position at an instantaneous velocity which is proportional to its distance from that position. In another embodiment of this invention, a protrusion is engaged by a horizontal arm which swings in a horizontal arc and interacts with a pivoting vertical arm which swings in a vertical arc parallel to the track. The sensing means is mounted on the vertical arm, and, as the horizontal arm is moved in becoming aligned with the protrusion, it displaces the vertical arm from its gravity based reference position so as to produce a signal to control the car's drive means.

An apparatus that employs a pair of high peripheral speed impact cutters to remove hard carbonaceous deposits from the lateral surfaces of the refractory lining of coke oven doors. The motion of these cutters is synchronized with that of an element of the apparatus which displaces it from one position to another on the door, and, in one embodiment, means are also provided to scrape tarry carbonaceous deposits from the door's seal ring.

Coke oven door cleaner

An alignment bar is fixed relative to each coke oven chamber and a pivotable member mounted to apparatus movable relative to the battery engages the bar of a coke oven chamber and in so doing engages electrical contactors that regulate the movement of the apparatus. The apparatus is properly spotted within a preselected tolerance when the pivotable member breaks contact.

Device for spotting within tolerance apparatus associated with the coke

A cleaner head is pivotally mounted to a shaft carried by an actuating arm that is so powered that, as the actuating arm pivots about an axis, the cleaner head, which is resiliently biased, engages and cleans the bottom surface of a coke oven door plug or lining.
