tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and 'to letters or figures of reference marked thereon, rich form a part of this specification.

This invention relates to a coke oven of the type in which two regenerators separated by a partitionare arranged under each oven and parallel thereto. In coke ovens of this type when regenerators are employed the air is heated in one of these regenerators while the products of combustion. heat the second regenerator.

This invention relates especially to an arrangement of the said coke ovens which, by

the simple manipulation of dampers, permits of utilizing them in any one of the following methods of operation: A, without recovery and without regeneration; B, with recovery but without regeneration; C, with recovery and with regeneration.

Theannexed figure shows a transverse sectional view of the battery of the ovens through the heating fiues, corresponding to a longitudinal section of one oven. In this figure the dampers occupy the-position corresponding to;method B.

Under the forward part of the ovens are provided the regenerators' 1- and 2, communicating at their upper part with the chamber 3 and at their lower part with the chimney 4. Similar regenerators 1 and 2' are provided at the rear part of the oven. Between the ovens heating flues 5 and 5; are arranged in familiar manner communicating through the openings 6- and 6, with the chambers 3 and 3.

At the extremities of the regenerator 1 are arranged vertical conduits 11 and 12 com-- municating with the chamber 3. This communication can be interrupted bydampers closing the communicating openings 13 and 14. Similar vertical conduits 15 and 16 are arranged at the extremities of the regenera- A damper permits of interrupting the communicatlon between the conduit 16 and the conduit 17 Another damper 20 permits of -1nterrupting the communication between the conduit 17 and the chimney.

The device is completed by several air and gas inlet conduits-which are specified in the course of the description given below of the three methods of operation.

In the case of method A, that is to say, without regeneration and without recovery, the openings 13 and 13 are closed, the openlngs 14, 16, 20, 14, 16, and 20 are open. The combustible gases arising from the dis 'tillation of the coal are conducted by the conduits 7 .and 7 into the chamber 8 surmounting the fines 5 and 5". Air is introduced into this chamber through the aper tures 9 and 9. The gaseous mixture thus obtained burns and. being divided into two parts descends through the two series of flues 5 and 5'. The part of the mixture which has traversed the flues 5,for example,

enters by the apertures 6 into the chamber 3, being then delivered directly to the chimney" bytraversing the conduits 11 and 16.

In the case of method of operation B, with recovery and without regeneration, the openings 20, 19, 14, 13 and 1-3 are closed, the openings 14', 16' and 20' are opened. The gases proceeding from the recovery works through the conduit 22 are conducted to the foot of the tines 5; They there encounter the air introduced through24 into the chamber 3 and having traversed the apertures 6, the mixture thus eflected burns and ascends through the flues 5, penetrates into the chamber 8, redescends by the flues 5, enters through the openings 6 into the chamber 3 and is delivered to the chimney 4 by the conduits 11 and 16.

In the case of the recovery and regeneration method C the openings 20,19, 14, 14', 19 are closed, the openings 13, 13 and 20 are open. The air delivered through the conduit 21 into the conduit-17 penetrates through the opening 25 intothe regenera-- tor 2, is partially heated there, passes through the opening 10, traverses the re- .generator 1 in which it continues to be heated and penetrates through the opening 13 into the chamber It then traverses the openings 6 and, as in the preceding method sivcly traverses the lines 5, the chamber 8,

the fines 5, the openings 6 and the chamber 8. The products of the combustion are then delivered through the opening 13 into the regenerator 1 and are delivered through the opening into the second regenerator 2, then through the opening 19 into the conduit 17, which conducts them through the opening 20 to the chimney.

Claims 1. In a device of the class described, in combination, an oven, a heating chamber, regenerating means associated with said oven at each end thereof, an air inlet associated with said regenerating means, and dampers adapted in one position to cause the air to pass through said regenerating means to said heating chamber, and in their other position to cause the air to pass into said heating chamber without traversing said regenerating means.

2. In a device of the class described, in combination, an oven, a heating chamber associated therewith, regenerating means operatively associated with said oven adjacent each end thereof, said means being positioned below said oven, a lower air passage below said regenerating means, an upper air passage between said means and said oven and communicating with said heating chamher, an air inlet associated with said first mentioned passage, and dampers adapted in one position to cause the air to pass through said regenerating means in passing from one to the other of said air passages, and in the other position to cause the air to pass to one side of said regenerating means in passing from one of said passages to the other.

3. In a device of the class described, in combination, an oven, a heating chamber associated therewith, regenerating means associated with said oven adjacent each end thereof, said means being positioned below said oven, a lower air passage, an air inlet associated therewith, an upper air passage communicating with said heating chamber, said parts being so positioned that air adiitted into the lower passage may be caused to pass through said regenerating means into said upper passage, and means for causing the air to passdirectly from the lower to the upper passage.

In testimony that I claim the foregoing as my lnventlon, I have signed my name in presence of two subscribing witnesses.
