GEORGE r. WARDLEY AND MATTHEW J. BUTLER, on JoL rET, ILLINOIS COKE QUENCHING APPARAT S if Application filed May 31, 1927. Serial No. 195,288.

Our invention relates to coke quenching apparatus and has for its primary object the provision of apparatus which automatically controls the length of time the coke is subjected to the quenching operation.

In the quenching operation of coke it is very desirable to subject a pre-determined quantity of coke, after it is removed from the oven, to the quenching action of water, an exact amount of time so as to properly quench the coke and not have an undue amount of moisture in the coke after it v has been quenchechwhich results from the use oftoo much water in the quenching operation. In the standard type of car into which the coke is discharged from the coke ovens and with the standard type of sprinkling apparatus in use for such car, it takes about twenty-eight seconds to properly quench the coke in using the water pressure which is common at most industrial plants. The timing 1 of the quenching operation is an important task-and has to be accomplished by means of stop watches or the like and very frequently the timing is not accurately performed, result ing in either an improper quenching ofthe coke through too short a time vor in the useof too much water and'cau sing an excessive amount of moisture in'thecoke. For these reasons it is highly important that the quenching operation be performed properly and as nearly automatic as possible, andthe primary purpose of our inventionis the provision of automatic quenching apparatus which is positive in operation and which is entirely automatic in its operation, requ1ring no attention on the part of the operator when the coke car is placed in position in the quenchingstation.

Another and further object of our invention isthe provision of. coke quenching apparatus which can be adjusted to meet varying conditions as to the size of car, the water pressure and the like, to meet various operative conditions, but when adjusted is automatic in its operation. I

Another and further object of our invention is the provision of coke quenching apparatus which is simple and eiiicient in operationpwhich is easy to install and which can be installed at aminimum of trouble and expense. These and other objects of our invention will be more fully and better understood by reference to the accompanying sheets of drawingsand in which Y Figure 1 is a plan view of the coke quenching station;

Figure 2 is a side elevational View ofithe coke and timing device for use in our ap paratus; a

Figure 3 is an end elevational view of the switch which forms a par of the timing device;

Figure 4 is an switch; and a Figure 5 is a wiring diagram s'howi'ng the wiringand various operating parts comprising the electrical equipment for the'system.

Referring now specifically to the drawings elevational View of trip and particularlyfto F igure l-illustrating a coke quenching station, a drain platform 10 V is shown having a track 11' positioned thereon and having a rectangular frame 12 which is positoned above the coke car 13 on the track 11 and which is supported over the supply pipe 16'is provided which is connect ed to the sprinkleripipes 14 and 15, the said water supply pipe having a valve 17 therein operated by a solenoid 18, by means of which the flow of water to the sprinkling pipes 14 and 15 is controlled. An electric locomotive 19i's 'shown'having a trip rod 20 extending outward therefrom and which is adapted to engage a switch 21 which is mounted upon a base 22 and has a pair of outwardly projecta ing members 23 and 24 in the formof a Y, which are so positioned that the triprod 20 on the locomotive 19 contacts with onevorflthe other of these members as the triprod passes the switch21. Apair of stops 25 and 26- are provided which contact against the sides of the switch tolimit its turning movement.- Referring now particularlyto Figures 2 and 3, whereina time switch and operating apparatus therefor is shown, a base 27 is shown having a motor 28 mounted thereon with a speed reducer 29 connected to the 7 motor 28 and which leads to a timeswitch comprising a frame member 30 secured to the base 27 in any approved manner and which has mounted therein a shaft'31 secured to a shaft 32 in the speed reducer 29 by meansof a coupling 33, a portion of said shaft 31 being;

' mounted. on the lower end of the arm;38.

Also mounted on said member 37 is a movable switch member 41having a contact member 42 mounted thereon at the lowerend of which is positioned a screw 43 having a lock nut 44 thereon, thesaid member 41 being mounted upon a screw 45 with a spacer 46 positioned against the face of the member :37" and around which a coil' spring 47 is por sitioned, one end of which engages the member 41 on itsouter side so that the contact 3 members 42 and 39 are normally heldin engagem'ent with each other; At the opposite side of the member 37 is mounted another 3 1 movable switch member 48-upon a screw 49 having a contact member 50 secured thereto and a screw 51 at the lower end thereof upon which a lock nut 52 is ositioned, these members forming a timeimit switch which is adapted to make and break an electrical operating circuit to the valve 17 as the nut 35 travels back and forth between the two points of the bolts 43 and 51 which are. alternately engaged by the head 36 on the nut35 as the device, is operated.

Referring now particularly to Figure 5 and wherein is illustrated the circuits used for operating. the device heretofore described, a-clapperfboard 53 is illustrated having a clapper 54 mounted thereon adjacent'and an solenoid. 55 with contact members 56and 57 mounted thereon. A second clapper 58 is provided adjacent an solenoid 59 on each side of which are a pair of contact members 60 and 61., A throw switch 62 is provided in the primary or operating circuit and from which I a'pair of wires 63 and 64 lead, the wire 63 goingdirect to the motor 28, the wire 64 leading to the contact member 57 whichis connected incircuit by a lead wire- 65 to the contact member60, each of the members 57 and 60 being adjacent one end of the clap pers 54 and58 respectively. Attached to one side of the switch 21 is a lead wire 66 which leadsto the contact member '42 carried by v the member 41 with the wire :67 leading to the solenoid. 55 and connected to the primary or operating circuit at 68, it being noted that this circuit is complete when the terminals of wires 66 and 67 in the switch 21 are connected through contact members 39 and'42. Leading from the clapper 54 is a lead wire 69 leading to the solenoid 18 on the valve 17 with a return'wire 70 leading from the lead wire 63 through a hand .switch 71 thus establishing a current throughthe solenoid 18 for operation of the valve 19 when one end of the clapper 54 is in'contact with the contact member, 57. At the opposite side of the switch 21 is a pair of terminals 72 and 73 having lead wires 74 and 7 5 connected thereto, the lead wire 75 being connected to the contact member 50 on the switch element 48 and the lead wire 74 leading to-the solenoid 59 where it is connected at76 to the'wirer67 and serving whenthe terminals 72 and 73 are connected through "the contact members 40 and 50 to energize the solenoid 59'pulling the clapper 58 out of its normal position as shown in the figure, so that one end thereof contacts with the contact member 60 and con-' nectlng the primary circuit so the motor is caused to travel in a reverse direction for the purpose of resetting the device after. its operation' is complete, .aswill be more fully described hereinafter. Awlead wire '77 is provided which leads from the switchmember 38 and is connected to the primary cir? cuit wire 63 at7 8 through which circuits are established tothe contact members 42' and 50 with the members 39 and: 40' respectively.

In operation the car .13 is backed into the quenching station underneath the spray-pipes" 14and 15 and as thecar is backed into-the.

station the rod 20 engages the switch arm 23 Wl'llCh forms a contact between the points66a and 67a andestablishing a circuit to the sole noid' 55, thus energizing this solenoid which pulls the clapper 54 down into contact with the contact. member 57. -Thisoperationalso establishes a. circuit through the leads 69 and 7 Othrough the solenoid-l8,'the switch 71 beingnormally placed in closed position so that the solenoid 18 becomingenergized opens the valve 17 and allows the water to flow through pipe 16 into the spray pipes14 and 15, causing a flow of water onto the coke contained in the car '13. The clapper 54 also closes the primary operating circuit to the motor 28 which thus starts to operate the gear reducing mechanism 29,, rotates the screw member 34, causing the nut 35 to travel along-the screw member 34' until it engages the bolt 43,

pushes the member 43 mounted inthe'e'nd of ber outward separates'the contact members .39 and .42 thus breaking the circuit leading the switch member 41 and pushing this inemcuit to the solenoid 18, shutting off the flow of water to the sprinkling pipes 1e and 15.

As soon asthe Water stops flowing, the car 13 is pulled from under the quenching station by the locomotive 19, the rod 20 engages the arm 24 of the switch 21 and connects the contact members 72 and 73 and closing the circuit through the lead wires 7 4 and 75 by energizing the solenoid 59 and operating the clapper 58, bringing one end of the clapper into contact with thecontact member 60 and which reverses the current through the motor 28 causing the motor to reverse itself and thus operating the screw 34 in. the opposite direction causing the nut 35 to travel backwards on the screw 34 until it engages the bolt 51 and breaking the circuit to the solenoid 59 by separating the contact members and on the member 48 so that the motor is stopped and the nut is therefore brought into reset position so that when the nextcar of coke is backed into the quenching station the rod 20 engages the switch arm 23 and the cycle of operations such as heretofore described is again completed.

The limit of travel of the nut 35 is controlled by the distance between the points of the screws 43 and 51 and consequently'the time of operation of the sprinkling apparatus is equal to the amount of time that it takes depending upon the pressure of the water and also the condition of flow, and whether muddy or clear and in general will amount to,

about twenty-eight to thirty seconds in order to quench a standard car into which the coke is received from the coke ovens before it 1s quenched. The adjustment'of these screws can, of course, be determined by experimentation so that thetime of flow of the water into the'coke is controlled without the use of any timing apparatus and is made entirely automatic by merely pushing the car into proper position and allowing it to remain in the quenching station while the quenching appae ratus causes the flow of water to flow onto the coke for the predetermined length of time. The rod 20 on the locomotive is so adjusted that when either of the members 23 or 24 on the switch is turned at an angle, the rod 20 will clear the points of these members so that it is immaterial whether the car of coke be spotted at exactly the proper place under the quenching station because pushing the car into the quenching station automatically starts the water to flow through the sprinkler pipes and pulling the car out causes the device to be reset for new operation.

While we have described more or less precisely the details of construction, we do not wish to be understood as limiting ourselves thereto, as we contemplate changes in form and the proportion of partsand the substitution of equivalents as circumstances may suggest or render expedient without departing our. invention.
