One object of my invention is to provide effective means for preventing smoke from a coking chamber from passing through the w hoppers of the charging truck during the charging operation.
A second object of my invention is to provide a charging truck having means for selectively sealing the charging opening whereby prevented from escaping into the-atmosphere and the danger of damage from explosions is avoided;
A further object of my invention is to provide means for insuring that proper condiw tions obtain in the hoppers of a charging truck before coal can be discharged therefrom.
in the operation of charging coke gases are generated very qnickl and in great volume when coal enters t e heated as chambers. This is particularly true when preheated coal is used. Inasmuch as considerable air is presenhan explosive mixturemay result that will be ignited at the rela tively high temperature in the chamber.
Accordingly, it is desirable to avoid the damaging efi'ects of such explosions. It is also desirable to prevent the escape of smoke and gases either through the hoppers of the truck or directly into the atmosphere below at the hoppers.
Larry cars, as at present constructed, are provided with heavy extensible sleeves for connecting the hoppers to the charging open- Gates control the discharge of coal likely in case of anexplosion.
' In accordance with the present invention,
' I provide alarry car having means for connecting the hoppers to the openings of the ooking chamber and that constitute also pressure-realist devices. The hoppers are particular relation to the pro-.
ovens;

sealed at their tops, whereby no smoke may pass through them whenthe gates are open."
In the accompanying drawings,
Figure 1 is an end view in elevation of a larry car constructed in accordance with my invention, parts being broken away; and
Fig. 2 is a side view in elevation of the 'larry car of Fig. 1, the top of a coking chamber being shown in section.
p A battery of coke ovens comprises individ ual coking chambers 11 the tops of certain of which are illustrated. As shown in Fig. 2, each chamber has a series of openings 12 through which the chamber is char ed.
Each chamber 11 is provided wit a standpipe 13 through which smoke and gases are PENNSYLVANIA, AS=
withdrawn. A steam jet 14 establishes sufiicient forced draft upwardly in the standpipe l3-that gas and smoke normally 'do not escape when one of the hoppers is being dis charged. The standpipe 1s provided with a pressure relief device 15.
A. larry'car 16 has a frame 17 of structural material and is mounted on wheels 18 that operate on tracks 19 extending across the ovens. The car 16 has four hoppers 20,21;
22 and 23 the operatin mechanism for which is controlled from afca 24. 'Each hopper has achute 26 that is adapted to register with corresponding openings in the oven tops. Each chute26- has a movable sealingbell 27 that seals the corresponding opening from the atmosphere when in its lowermost or extended position. I 1
Each sealing bell is controlled by a lever 28 that is connected theretoby a link 29, a. rocker arm 30; a rock shaft 31, and a pair of rocker arms 32 that are respectively connected to opposite sides of the bell. a lost-motion connection to the arm 30. The chutes 26 are each controlled by a gate 34 that is connected to an operating lever 35 by means of a link 36,'alever 37.. and a link 38.
Each hopper is provided with a slid-able cover 40. The position of the covers are con trolled by racks l1 and pinions 42, the latter being mounted on a common shaft 43 that may be rotated by a crank 44 in the cab 2 i and havin a sprocket-andchain connection 415 to thee aft 43.
The link 29 has I cylinder 53. The lever 50 The covers are each held in position by clamps 46 that are connected by means of springs 4L7, arms 48 and a common rock shaft 49 to a lever arm 50. The lever 50 is connected at its lower end to a piston rod 51 that is rigidly connected to the piston 52 of a is interlocked With the covers 40 by means of a hook 54 that engages 2. lug on the top of the cylinder 53 and a link 55 and arms 56 and 57 that control the hook Min-accordance with the positions of the several covers.
The lever 50 is interlocked also With the levers 35 for controlling the gates 34. An arm 59 having a detent bar 60 prevents the operation of each of the levers 35 except When the lever 50 occupies an operative position as will be later described.
It may be assumed that the hoppers of the larry car 15 have been filled with coal from the storage bins or preheater. The covers 4C0 are closed by means of the crank 44 at any time after the hoppers are filled. One of the covers 40 engages the arm 57 and actuates the connected mechanism to the position indicated by dotted lines to disengage the hook 5 1:. i
\Vhcn the car is over the next coking chamber 11 to be recharged, connection is made at (32 between a steam supply pipe 63 and a steam pipe 6 lthat is connected to the cylinder 53 and through the cylinder and branch pipes comprising apportioning discs (35 to the space between the surface of the coal and the cover of each of the hoppers. lVhen a'valve 66 is opened, steam enters the cylinder 53 and actuates the piston 52, rod 51 and lever 50 to the le'tt'as shown in Fig. 1. The arms 48 thereupon move downwardly to tightly clamp the covers l0 and the arms 59 move upwardly to remove the detent bars 60 from the corresponding levers 35. Steam also enters the upper spaces of the hoppers and drives out any air therein.
Before the hoppers are discharged, the lovers are actuated forwardly to lower the scaling'hells 27 to seal the openings 12, the usual lidsorcovors having been previously removed. Une of the gates, preferably the one or the hopper iatthest "rom the standpipe 13. is then opened and ":l
dcr normal condition... are produced innnediat able cpiantities but ihrough the st zu p through the openi f toe sealing bells with the st hoppers a mi exerts cer against that of the pressure is preferably his gases in the coking chamber.
.ilovvever, since the ovens have filled with air upon being previously emptied of its product or coke, an explosion may occur upon the contact of the coal dust with the highly heated Walls of the coking chamber. No damage results, however, the sealing bells 27 and the connected rocker arms 32 readily lifting to permit the gases to escape ten1po= rarily and thus relieve the excessive pressure in the coking chamber. This action is permitted by reason ofthe lost-motion connection between the link 29 and the arm 30. The bells 27 drop back to again seal the openings When the pressure has subsided.
The-remaining hoppers are discharged 1n any desired order, the sealing bells functioning as described above to retain the gases and smoke and to constitute pressure-relief devices in case of explosion.
When the hoppers are empty, the gates 34 are closed by their levers 35, the valve 66 is closed and an exhaust valve 67 is opened whereupon a spring 68 returns the lever 50, 3 piston rod 51 and piston 52 to their normal positions. .The arms d8 accordingly release the covers 4C0 and the arms 59 return the detent bars 60 to lock the levers in the closed position of the gates. The steam pipe is then disconnected at 62, the sealing bells are lifted by their levers and the openings 12 covered by the usual heavy lids. The covers lO may be opened at any time prior to the filling of the hoppers for the succeeding charge.
it Will be noted that l have proviced larry car having means for cllectually sealing the charging openings of a coking chamber and which constitute p essure-relief devices for avoiding dan'iage in case of an ex.- plosion. T have provided also means for sealing the hoppers mechanically and by fluid pressure to prevent the escape of gas and smoke through the hoppers.
The covers the hoppers and the leve for the gates are interlocked whereby LL18 hoppers cannot be dischawed until the o are are in no on and stc on l entered trio spaces abov ;l'
