Abstract
Abstract A coke quench car having a slanted bottom and discharge opening in one wall is provided with a movable grate at the discharge opening to drain water and retain coke. A door outboard of the grate closes the discharge opening in a substantially liquidtight condition and accumulates quench water in the car to submerge the coke. Means are provided for selectively opening the door to drain only water at the quench station and for later opening the grate to discharge the quenched coke at the coke wharf. A second embodiment provides a tilting bottom coke car with a first sealing means for sealing the car in substantially liquidtight condition to accumulate water and submerge the coke. A second sealing means are provided to permit the floor to be tilted to a liquid discharge position to drain only water. Means are provided for tilting the floor between an open and closed and intermediate liquid discharge position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
212 words
In a coke quench car equipped with: a. a support frame, b. a coke basket on said frame defined by: 1. a pair of spaced end walls connected to said frame; 2. a front panel extending between said end walls connected to said end walls, spaced above said frame; 3. a floor between said end walls, disposed above said frame, pivotably mounted on said frame; and 4. a back wall extending between said end wall connected to the back edge of said floor; c. whereby coke is retained in said basket when said floor is pivoted to a closed position and coke is discharged when said floor is pivoted to an open position, the improvement comprising: 1. first sealing means along the lower edge of said front panel for providing a substantially liquid-tight seal between said floor and said front panel when said floor is in the closed position, to retain coke plus liquid in said basket; 2. a second sealing means along the lower edge of said front panel for discharging liquid and retaining coke in said basket when said floor is pivoted to a liquid-discharge position intermediate the open and closed positions; and d. means for pivoting said floor between said open position, said closed position, and said liquid-discharge position.

Claim 3
Dependent Claim
17 words
a front panel extending between said end walls connected to said end walls, spaced above said frame;
Claim 4
Dependent Claim
17 words
a front panel extending between said end walls connected to said end walls, spaced above said frame;
Claim 5
Dependent Claim
64 words
The invention of claim 1 in which said first sealing means includes: a. a downwardly extending plate below the lower edge of said front wall having an upper portion adjacent the lower edge; and b. a lip on said plate at the upper portion contacting the front edge of said floor in a substantially liquid-tight fashion when said floor is in the closed position.
Claim 6
Dependent Claim
54 words
a second sealing means along the lower edge of said front panel for discharging liquid and retaining coke in said basket when said floor is pivoted to a liquid-discharge position intermediate the open and closed positions; and d. means for pivoting said floor between said open position, said closed position, and said liquid-discharge position.
Claim 7
Dependent Claim
54 words
a second sealing means along the lower edge of said front panel for discharging liquid and retaining coke in said basket when said floor is pivoted to a liquid-discharge position intermediate the open and closed positions; and d. means for pivoting said floor between said open position, said closed position, and said liquid-discharge position.
Claim 8
Dependent Claim
44 words
The invention of claim 2 in which said second sealing means includes: a. a perforated lower portion on said plate, the perforations sized to drain liquid but retain coke when the front edge of said floor is adjacent the perforations in the liquid-discharge position.
Claim 9
Dependent Claim
16 words
