To all whom it moy concern:

Be it known that I, EnN-s'r HUGO Hau- MANN Knauer, u. citizen of the Empire of Germany, residing at Hamburg, Germany, have invented certain new and useful I lnprovements in Apparatus for Quenchnig Incandescent Materials, of which the followin is a full, clear, and exact description.

is invention relates to apparatus -for quenching incandescent materials .and is purticularly adapted for dealing with cokeni large quantities, such as produced, for lnstance, 1n retorts working with large charges.

The object of this invention is to effect 1n as speedy und thorough manner as possible the quenching of such large quantities of coke 1n the trough of a'traveler movable on rails in front of the retorts. As in such case the walls of the quenching trough are apt to be damaged by becoming excessively hot owing to their contact. with the incandescent coke, it has already been suggested to make the lateral walls of the trough hollow and to cool them by water circulation, the upper Walls having previously been in the form of a hood above the trough and provided with a longitudinal slot through which water contained therein could flow on to the coke in the trough.

According to this invention the Water- ]aclreted quenching trough is of the special construction hereafter described and apparatus is provided for conveying water to the coke in the trough so as to insure the most thorough and rapid quenching thereof.

A coke quenching apparatus constructed according to my invent-lon is illustrated in the accompanying drawings in which- Figure l is a vertical sect-ion of the apparatus mounted on the traveler, and F ig. 2 en elevation of the same, partly in section, seen from the left hand side.

The quenching trough 1 is mounted in thc center of a traveler which is movable, as is well known, in front of the gas generating retorts. The lateral walls Q as Well as the bottom 3 of the trough are formed double, and adapted to have water circulated throu h them for cooling purposes. The Intera walls 2 of the extinguishing trough are sti'ened inside by means of ribs which, however, are of such construction that the water used for cooling the walls can freely flow through the hollow space of the walls.

The trough is open at the top and openings are formed in the upper portions of the side walls Q through which cooling Water can pass into the interior of the trough 1.

The wall which is on the left hund side in Fig. 1 is provided at its lower end with a movable discharge door 4 which also has double walls and can he opened or closed at will from the central platform of the traveler by means of a sprocket and chain gear G and 7 to empty the contents of the trough. The gear chains 7 pass over the sprockets S mounted on the outer ends of thc door pivot.

vater is supplied to the walls 2 and to the bottom of the trough through a pipe 9 lead ing into the bottom of the trough and suitab y connected with a source of water supply to permit the traveler to he shifted, while the hollow door l is supplied with water by means of a flexible pipe 10 connected to the upper p ortion of the corresponding lateral Wall 2. The door 4 is provided near its upper end with openings 11 whereby the coke contained in the lower portion of the trough 1 or falling from the same, is sprinkled with water.

In the construction illustrated, there is further provided in the interior of the trough 1 a hollow cross-bean1 12 to which Water is supplied through pipes 13 from the hollow lateral walls 2, this Water passing through lateral openings 14 in the beam to the heart ofthe mass of coke in the trough. The beam 12 is at the same time utilized as a bale, since it separates and divides the coke falling on it from the retort into the trough 1, and thus assists its quenching.

In front. of that lateral wall 2 of the trough 1 having the discharge'door, a partition 15 is provided at. the required distance forming an exhaust passage for the steam or fumes, the upper portion of which opens into the central tower-like chimney 1G of the apparat-us through which steam generated during the extinction of the colte is carried up- Ward in the woll known manner, thus protectng the attendants from danger.

The trunsfcr of colic from the retorts to the quenching trough i is clicctcd by means of chutes 1T arranged at one or both sides of thetruvclcrand (.ipcningintothc trough l.

in operation the coke discharged into the trough 1 will be quenched all over its upper surface by water from the openings 5 in the water escaping through the openings 11 of the watercooled door 4. Owin to theeoke being simultaneously c xtinglus ed through out, quenching takes glace in a rapid and p "z thorough manner.

i owing to the cooling' of all the walls, as well as of the bottom and discharge door of the n the other hand,

trough, the latter is not excessively heated by the incandescent coke and is not therefore damaged.

The apparatus illustrated is also provided with mechanism whereby the movement of the traveler can be controlled from the central platform for actuating the discharge door and the door of the retorts it is desired to empty.

The platforms of the traveler are arranged in such a manner that cleaning of the retorts or repairs thereto can be conveniently effected.

Finally, the apparatus illustrated is adapted to carry any mechanism or parts required for attending to the retorts, but such mechanism forms no part of the present inven tion and is not therefore shown or described.
