To whom it may concern:

Be it. known that I,- Cnannns H. HUGHES,

-a'jcitizen-of the United States, residing at Syracusefin the county of Onondaga. and

Stateof New York, have invented certain new and useful Improvements in Retort Coke-Ovens, 'of which the follow-ing* 1s a specification.

' My inventlo relates particularly to the type of oven shown in UnitedStates Lett}SPittent llo. 970,720, and the object of my improvemen ,is to'provide a simple system of distributing lues for the air of combustion and the waste gases and an arrangement of controlling valves whereby,

through the heating ilues of the oven and through the regenerators is reversed, the air `will be admitted through the heated regenerator to the heating ilues and burners in the most. direct manner without first having tosweep out thewaste gases of combustion from a waste gas flue, and no waste gas will continue tonbe sent through the heated regenerator.

My invention will be' best understood by reference to the accompanying drawings, illustrating an embodiment thereof, Figure 1 of which'shows a vertical longitudinal section through one oven of a block, and

Fig. 2 shows a horizontal section on the line 2-4-2 Figzl.

. 3, running longitudinally of the Referring tothe drawings, A indicates the oven below which are located two re` generators, 1, 2, the construction being the same for each oven of the block. Below the regenerators are located waste gas tlues,

4, 5, and, between these, an air 'sulply iue ovens. AThe waste gas dues 4, 5', are connected respectively with the regenerators 1,

v2, by'passages 7, 10, and the air iiue, isA

. 4also connected with the regenerators 1, 2,

by passa es 8, 9.. Thepassages, 7, 8, ane controlla by a single valve 11, sagrranged .that when one ,of the passages as, 7;, is-closed by the valve the passage, 8, is open, and vice versa. The passages, 9 and' 10, are controlled in the same manner by valve 12,l and the valves 11,12, areI arranged to `o crate chronously so thatl one or the o. er of t e passages, 8, 9,'fro1nv the air flue 3 is al? ways open so that air is continuously ow lock of" ingfrom air Hue 3 `to oneQor the other of regenerators 1, 2, and thence to the heating dues 4of the oven in one direction or the other. f

The synchronous operation of al1 the valves, 11,12, kof the oven block is effected by the following described means. The valves 11, are each connected by a rod, 13, with ,an -arm,i14.,. secured to a rotatable rod, 15, running along one side of the block, or .battery,.of ovens and the valves, 12, are in the same Ina-nner connected by rods, 16, to arms, 17, secured `to a rotatable rod, 18, running` along the other side of the block of ovens.l At the end of the block of ovens 4the rods, 15, 18, are provided with means for eiectin their synchronous rotation, such as a rod, 19, connected a-t its ends to levers, 20, 21, secured respectively to rods,

ing in cylinders, 22, 23.

When 1t is desired to reverse the vdirecpassages,'10 are openedand 'the passages, 7, are close Thus the waste gas begins to ,flow through regenerator, 2, and into tlue 5 while air,which is always under res- L'sure in ',flue, 3, begins to flow directly tlrierel from into the 'heated regenerator, 1. By means of a chain, 24, connected with the rod, 19, andr passing around the spindle of valve, 25, which controls the 'outlets of waste gas ues', 4,' 5, one of these lines is' closed and the other opened by the same movement which o ens and closes the passages, 7,10.

It wil be understoodv from the foregoing that upon shifting the position of the valves, 11, 12, reversal of the gas current is instantly effected, without any tendency of vthe waste gas to continue to flow through the heated regenerator, and the supply of 'airjfor combustion enters vthe heatedl regenerator instantly and directly with no admixture with waste roducts of combustionexcept for the neg igible quantity con- 15, V18, )and also connected to pistons Work# tion of the gas current through the regen-` sagcs, 9, is* closed. A t the 'saine time thetained in the regenerator, so that tlie'lburners are constantly supplied with air and there is no loss of combustible gas.

When it is desired to cut an individual oven out of operation, as forrepairs, the rods, 13, 16 ma be disconnected from the arms 14, 17, an the valves moved so as to close the passages 7, 10. Cold air will then circulate through the heating lues and the oven is thus made easily accessible.

What I claim as new and desire to secure by Letters Patent is 1. The combination with a horizontal flue, retort coke oven of a pair of regenerators located below the oven and parallel thereto, two waste gas ues and an intermediate air flue located below the regenerators, a passage connecting each of the Waste gas iiues with one of directly connecting the air llue with both regenerators, valves controlling said pasthe regenerators, passages' Loewe@ sages and means for moving said valves so as to synchronously shift the connections between the regenerators and said ues.

2. The combination with a retort coke oven having horizontal heating lilies connected `in series of a pair of regenerators `connected in series with the heating lines, two waste gas flues, means for'alternately connecting 'the regenerators with the waste gas flues and an air Hue located intermediate the Waste gas llues and providedwith passages leading directly to each of the regener'ators.

In testimony whereof, I have hereunto subscribed my name, this 7th day of August A. D., 1912.
