ABSTRACT:
An upstanding support is provided and a carriage is mounted on the support for vertical reciprocation between predetermined upper and lower limit positions on the support. A jamb cleaning head is mounted on the carriage for vertical reciprocation therewith along and for cleaning an adjacent upstanding jamb portion. A support structure stationarily positioned relative to an associated coke oven jamb and mounting structure is provided for supporting the upstanding support relative to the stationary support structure for vertical shifting relative thereto. First drive structure is connected between the support and the carriage for driving the latter along the former between the aforementioned limit positions and reversible second drive structure is connected between the stationary support structure and the upstanding support for reversibly variably shifting the upstanding support relative to the stationary support structure. Further, actuator structure is provided for the second drive structure and is operative to sense upper and lower limits of an upstanding jamb portion with which the cleaning head is operatively associated and to actuate the second drive structure to lower and raise the upstanding support relative to the stationary support structure in response to sensing upper and lower limits, respectively, of the jamb portion whereby the upper and lower limit positions of movement of the carriage relative to the upstanding support may be achieved by downward and upward shifting, respectively, of the upstanding support relative to the stationary support structure when the vertical spacing between the upper and lower limits of the associated jamb is less than the vertical spacing between the upper and lower limit positions of vertical reciprocation of the carriage relative to the upstanding support.
