BRITISH COMPANY COKE DISGHARGER FOR RETORTS'FOR THE GARBONIZATION OF GOAL AND THE DIKE Application filed March 14, 1932, Serial No. 598,852, and in Great Britain May 7, 1931.

This invention relates to coke discharging means for vertical retorts for the carbonlzation of coal and the like, and has for its object to provide improved and simpllfied d1scharging means of the intermittently operating type. j v

The invention comprises a pivotally mounted coke chamber forming a closed receptacle for'the coke with a hinged coke discharge door and locking means therefor at one side thereof, and an arcuate projection for closing the connection between the coke chamber and the retort at the opposite side thereof, and means for raising and lowering the coke chamber to make a gas tight joint between the arcuate projection and the bottom of the retort and for removing any pressure between said parts to facilitate their relative movements.

The invention further comprises the arrangement in which the coke chamber is carried by eccentrics upon a shaft beneath it about which the chamber pivots, the shaft being turned to raise and to lower the coke chamber. j

The invention further comprises the arrangement in which the coke chamber has a fixed bottom sloping downwards towards the side of the chamber at which the discharge door is situated, the said door extending to the level of the bottom of the chamber and when released by its catch opening automatically to permit of coke discharge.

The invention further comprises the arrangement in which the coke discharge door is hinged o-r pivoted at its upper end and constitutes practically the whole of one side of the coke chamber.

The invention further comprises securing means for the coke discharge door which proj set through the bottom of the coke chamber and are operated by a handle upon a cross shaft beneath the coke chamber, and a spring holding the securing means normally in service. 7

The invention further comprises the provision of a table movable up and down within the coke chamber in order to control the rate of descent of coke into such chamber from the retort.v

Referring to the accompanying explanatory drawings Figure 1 is an elevation partly in section, illustrating the lower portion of a retort with coke discharging means thereon ar,

we employ a pivotally'mounted coke cham-:

her a, which is adapted when coke discharge is to be effected to be broughtto the position shown in Figure 3, beneath the steaming chamber 1) which is an extension ofthe retort proper 0, so that the coke can drop into the coke chamber which is then swung to the pos tion shown in Figure 1 with an arcuate pro ection 03 at its upper end closing off the lower end of the steaming. chamber 6 of the retort, and a door 6 at the side of the coke chamber being opened to permit the discharge of the chamber contents.

The coke chamber is pivoted at its lower end, the pivot shaft f having eccentric bushes g secured thereon which turn in upon the underside of the coke chamber, so as to apply sealing pressure between thearcuate projection 03 on the coke chamber and the bottom of the steaming chamber 6 to make a gas tight joint between the said parts.

The pivotal shaft f has a pair of slotted crank arms 2' thereon in which engage the ends of a cross head 9' upon a screwed shaft is having a hand wheel mthereon. It will be seen, therefore, that by turning the handwheel m in one or other direction, the pivotal shaft can be turned to cause the eccentrics 9 either (1) to raise the coke chamber a and cause the part d to make a gas tight joint with the bottom of the steaming chamber 7),

parts It delivery ough the door.

or (2) to lower the coke chamber to allow it to be turned freely from the Figure 1 to the Figure 3 position, and vice versa.

It will be understood that the coke chain- 5 ber is only brought into line with the retort and steaming chamber, as shown in Figure 3, when coke discharge is to be eifected and then only for theishort period necessary for coke tofall into the chamber.

The delivery door 6 upon the coke chamber extends the full width and practically the full depth ofthe latter. It is hinged at e at its upperend and when the coke cham;

ber is in the delivery position; the release 'of the door catch a n will result, in the door opening and moving to a Vertical position, as shown inFigure 1. The bottom o of the .c 'ke chamber v imclin'es downwards rewards the door side the chamber to facilitate coke Tx'vo catches as n extend alrpu h titles in the bottomo of the coke chamber and are carried by upon a messiah j wliichis .turnedbyahan'dle i1 against the pressure of a spring t whichteiids to holdthe catches normall iii their service positions, as shown in Figure 1. i

, The coke chamber a is turned abont its pivot shaft by tli'e "crank arm a and connecting link a. The crank arm is turned the worm Wheel, and worm a the latter beingiipon a vertical shaft 3 with a handle a uppii itslower end. A pawl (not shown) can eng ge he to th Par 3 p h haf to prevent return movement of suchshaft, i In caseswhere it is not de si red to allow coke to drop to the bottom of'the coke chamber when the latter brought-into line with the retort a platform (4 (see Figure 4 in the chamber a, may be raised to the top of the chamber to support the coke and then lowered 1 into the chamber, after which the coke is discharged through thedoor e at the chamber side.

The fswivelling of the coke chamber may be effected by hand for small installations.
