Quencher car spotting interlock

Claim 1

A SYSTEM WHEREBY A COKE OVEN QUENCHER CAR IS SPOTTED RELATIVE TO A COKE GUID AND INDICATES TO A PUSHER MACHINE WHEN SAID QUENCHER CAR AND A COKE GUIDE ARE PROPERLY SPOTTED, WHEREIN THE IMPROVEMENT COMPRISES: A. A TARGET ON SAID QUENCHER CAR; B. A PROBE MOUNTED TO SAID COKE GUIDE; C. MEANS FOR EXTENDING AND RETRACTING SAID PROBE WITH RESPECT TO SAID TARGET; D. AN ELECTRICAL CONTROL CIRCUIT INCLUDING A SWITCH IS SAID PROBE THAT CLOSES WHEN SAID PROBE CONTACTS SAID TARGET; E. A RELAY IN SAID CIRCUIT THAT IS ENERGIZED WHEN SAID SWITCH CLOSES; F. MEANS IN SAID CIRCUIT ACTING IN RESPONSE TO SAID RELAY THAT COMPLETES SAID CIRCUIT; AND G. MEANS FOR SENDING A SIGNAL BY SAID CIRCUIT TO SAID PUSHER MACHINE INDICATING THE PROPER SPOTTING SAID QUENCHER CAR RELATIVE TO SAID COKE GUIDE.

Claim 2

A SYSTEM WHEREBY A COKE OVEN QUENCHER CAR IS SPOTTED RELATIVE TO A COKE GUID AND INDICATES TO A PUSHER MACHINE WHEN SAID QUENCHER CAR AND A COKE GUIDE ARE PROPERLY SPOTTED, WHEREIN THE IMPROVEMENT COMPRISES: A. A TARGET ON SAID QUENCHER CAR; B. A PROBE MOUNTED TO SAID COKE GUIDE; C. MEANS FOR EXTENDING AND RETRACTING SAID PROBE WITH RESPECT TO SAID TARGET; D. AN ELECTRICAL CONTROL CIRCUIT INCLUDING A SWITCH IS SAID PROBE THAT CLOSES WHEN SAID PROBE CONTACTS SAID TARGET; E. A RELAY IN SAID CIRCUIT THAT IS ENERGIZED WHEN SAID SWITCH CLOSES; F. MEANS IN SAID CIRCUIT ACTING IN RESPONSE TO SAID RELAY THAT COMPLETES SAID CIRCUIT; AND G. MEANS FOR SENDING A SIGNAL BY SAID CIRCUIT TO SAID PUSHER MACHINE INDICATING THE PROPER SPOTTING SAID QUENCHER CAR RELATIVE TO SAID COKE GUIDE.

Claim 5

A system whereby a coke quencher car is spotted relative to a coke guide and indicates to a pusher machine when said quencher car and said coke guide are properly spotted, wherein the improvement comprises: a. a target on said quencher car; b. a probe mounted to said coke guide; c. an electrical control circuit including a sensing probe actuator; d. a signal switch in said circuit which when closed allows electrical current to energize said probe to advance it toward said target; e. a switch in said probe that closes when said probe contacts said target; f. a time-delay relay in said circuit that is energized when said signal switch closes and that, after the passing of a preset time interval, reverses said probe actuator and retracts said probe; g. a relay in said circuit that closes when said switch in said probe closes thereby completing said electrical circuit; and h. means for sending a signal by said circuit to said pusher machine indicating the proper spotting of the quencher car relative to said coke guide.

Claim 6

A system whereby a coke quencher car is spotted relative to a coke guide and indicates to a pusher machine when said quencher car and said coke guide are properly spotted, wherein the improvement comprises: a. a target on said quencher car; b. a probe mounted to said coke guide; c. an electrical control circuit including a sensing probe actuator; d. a signal switch in said circuit which when closed allows electrical current to energize said probe to advance it toward said target; e. a switch in said probe that closes when said probe contacts said target; f. a time-delay relay in said circuit that is energized when said signal switch closes and that, after the passing of a preset time interval, reverses said probe actuator and retracts said probe; g. a relay in said circuit that closes when said switch in said probe closes thereby completing said electrical circuit; and h. means for sending a signal by said circuit to said pusher machine indicating the proper spotting of the quencher car relative to said coke guide.
