COKE-HANDLING CAR.

Application filed May 11, 1922. Serial No. 560,040.

To all whom it may concem:

Be it known that I, LEONARD KIPP, a citizen of the United States. and a resident of Waterbury. county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in- Coke- Handling Cars, which the following is a specification.

This invention relates to coke-handling apparatus and moreparticularlyto a car for holding red-hot coke while it is being quenched. i I

()ne object of this invention is to provide a. car for transferringhot coke from the retort of a gas or coke plant to the quenching apparatus which may be located at a considerable distance from said retort.

A further object is to provide a cokehandling car having a water jacketsurrounding the metal walls of the coke receptacle and adapted to prevent said walls from overheating. i

A further object is to provide a 'c0ke-handling car having a water-cooled dumping or discharging doo'r. I

A further object is to provide a coke handlingi car of the above nature which will be simplein constructionpcheap to manufacture, and very efficient and durable in use.

With these and other. objects in view there has been illustrated on the accompany- .ing drawings one form in which the invention maybe conveniently embodied in practice. I

description, the re- In the usual process of manufactlilring coal gas and coke, it is customary to heat coal 1n suitable retorts to a highteniperature until the gas is driven off and the coal .is converted to coke.-.. The redhot coke is then ejected from the retort, quenched by sprinkling with water. and. stored in suitable bins or pits until needed.

According tothe practice now in common use, the red-hot coke, as it falls by gravity from the retort drops into a single-walled receptacle composed of riveted iron plates. This receptacle,- which is usualiy mounted upon wheels, is then moved over rails to a distance from the retort, and a spray of is introduced from. an overhead sprinkling pipe to quench the, coke. The car is then emptied by openingthe discharge door and allowing; the quenched coke to. fall by gravity into suitable cokehins or plts.

Considerable difficulty has been experienced in the use of the present type of sin gle-walled coke receptacle, on account of the severe stressesand strains set up in the iron plates by the alternate contact with red-hot coke and the quenching water. It hasbeen found in practice-that these stresses and strains cause the plates to quickly buckle or warp out of shapeand become cracked so that the car has to be frequently taken out of service torrepairs- Not only is the use of the car-thus lost for a considerable period, but the cost of repairing it is generally quite higln Moreovergthe life of the present single-walled coke-handling car is very short, its depreciation being extremely rapid. I 1 e \Vith'the present invention the above and disadvantages have metal walls of the coke receptacle surrounded by a water-jacket, in order to prevent said walls from overheatingand thus eliminate bucklingwarping and cracking of the For convenience in spective front, side. and rear edges of the coke-handling car. its platform and supporting beams will be designated to correspond with the adjacent edges of the coke receptacle, the'edgeot the latter in which 7 been largely avoided. This has been. accomplished by providing a coke-handling car having the cross beam.

- drum.

the door is mounted being arbitrarily chosen as the front.

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral 10 represents a pair of side platforms one of which is locatedon either side of the car. The. side platforms 10 are mounted upon the horizontal end channels 11 and the three cross beams 12, each of which cross beams comprises a pair of U- shaped channel members arranged. back to back, and secured together in any suitable manner as byriveting and welding.

The front and rear cross beams 12 have depending therefrom a pair of bearing blocks 13 and 13 in which are mounted ,the axles 14 sapported upon the wheels 15 which are adapted to run upon the rails At the inner edges of each side platform 10, a paircof upwardly extending angle members 18 and 19 are provided, said member being riveted or otherwise secured to the outer walls 20 and 21 of the side jackets of the coke receptacle. Each side of the receptacle is formed in the shape of a trapezium, and is provided with a horivzontal top portion, v'ertical end portions,

and a bottom portion inclined forwardly and downwardly.

f The coke receptacle is also providedwith a rear inner wall 24, abottom inner wall 25,:1 pair of side inner walls 26 and 27, secured in spaced relation to the adjacent. outer walls 22, 23, 20, and 21 respectively, whereby water-jackets will be formed around the inner walls of the coke receptacle. In order to hold the adjacent walls of the waterjacket in spaced relation, a plurality of vertical spacing channel members 28, 29, 30, 31, 32, 33, 34 and 35 are provided in the side and rear jackets respectively. The inner and outer walls of the base jacket are I held,- in spacedrelation by means of four inclined channel members 36, which form continuations of the vertical rear jacket spacing channel members 32, 33, 34, and 35, previously mentioned.

In order to permit water to circulate freely between the several sections of the jacket, each of said. spacing channels 36 isprovided with elongated apertures 37.

The front of. the receptacle is closed by I Th e means of a door the frame of which consists of the front ends of the side and base jackets, and a top cross-beam 38 composed of two channel members secured back to back.

In order to permit the removalof the coke after it has been quenched, a discharge door 40 is pivotally supported from the cross beam 38 by means of a series of T- similar to the jackets of the side and rear walls previously described.

In order to permit evaporation to take place freely, each of the side, rear, and door jackets are left open at the top, where- .by the walls of the coke-receptacle will be prevented from overheating. Strainers 41 are also provided in order to prevent coke andother materials from falling into the open jackets. These strainers 41 which cover the top of the rear jacket and extend about two thirds of the length of the side jackets, are preferably made from wire mesh as clearly shown in Fig.- 3, but if desired. mayalso be made from a V-shaped strip of sheet metal 41 having suitable perforations as shown in Fig 4. In order to assist in discharging the coke into the coke-bin, an apron 42 is riveted to the base of the bottom jacketof the receptacle, as clearly shown in Figs-1 and 2. This apron 42 serves to keep the quenched coke from coming in'contac't with the axle, the axle; bearing, the wheels, and the track. The top door-supporting cross-beam 38 is itself supported by means of a pair of vertical triangular brace members 43 and 44. brace members 43 and 44 are secured to the side platforms 10 by means of suitable angle members 45, and the hra-ce members 43 and 44 are provided with a pair of rectangular apertures45 and 46 to permit door-operating rods 47 to freely reciprocate therein. Each of the door-opens ating rods 47 is preferably rectangular in section, and is pivoted at its forward end to an angle bracket 48 secured to an I-beam 4-9, the latter being held upon the door by means of a series of hangers or brackets:

in a U-shaped bracket bolted to the left hand platform near the' rear end thereof, as vlewedinFig. 1. Mounted upon the arms 55'and 56 ofmthis U-shaped bracket 54* ackets.

holes 61.

i'sa pinion shaft 57 carrying the pinion 54 which meshes with theg'ear 52previously described, and said shaft 57 is also provided with a handle 59 secured at its outer end. Intl1e modified form of door mounting shown in Fig. 6, instead of hinging the door, at the top cross-beannthe dooris hinged at its central portion. Each side of the door has a bracket 62riveted thereto, as clearly shown in Fig. 6, and each bracket 62 is provided, \Vltllit' horizontal trunnion 63 integrally formed therewith. Each of the trunnions 63 ismounted'to rotatein a bearing member 64: riveted or otherwise secured to the forward ends of the side In order to permit the removal of any sediment which may gather in the jacket,

the bottom forward portions of the side jackets are provided with suitable hand In operation, the coke-handling car is first drawn up upon its tracks'beside the retort from whichthe coke is to be ejected. This is accomplished by means of the cable or chain previously mentioned. The retort is then opened, andthe'red-hot coke will fall by gravity into the rear of the cokereceptacle, andwill slide along the inclined bottom 2:") until itrests against the door 40.

As willbeevident, the-hot coke will be kept from injuring the metal with which it isin contact by the water in the jackets. The heattransmitted fromthe coke through the jackets will be rapidly absorbed by the Water, which after a short time will be brought to the boiling point. Evaporation from the jacket water will still; furthen assist in cooling the metal in contact with the hot coke. The strainers on the rear jacket and on the'rear portions of the side jackets will prevent any coke. dirt, or other objectionable materials from falling into the jackets which might have a tendency to clog them up, and thus reduce their efllciency.

When a charge of cokehas been completely ejected from the retort, the car will be drawn along the rails away from the oven, and the hot coke will be quenched by spraying it with water from suitable sprinkling apparatus. The sprinkling apparatus will also replenish any water which may have evaporated from the open water jackets.

When the coke has been completely quenched, the operator will open the door water-cooling the at the front of the car by turning the loandle 59 in its proper direction permitting the quenched coke to fall by gravity into the cokepits as has been previously described.

It will thus be seen that by'means of this invention, an improved water-cooled coke-handling car has been provided in which buckling, warpii'l andcracking of the. plates will be reduced 'to the minimum. It will also be seen that this invention will reduce the expense of ups-keep, cut down depreciation, and will permit thecoke-ha-ndlingcar to be kept in service, practically without interruption.
