Specification of Letters Patent. 1 Patented A131 26,1921.

Application filed December 2, 1918. Serial No. 264,964.

To all who'mjz't may concern:

Be it known that I JOSEPH BECKER, a citizen of the United tates, and residing in Pittsburgh, in the county of Allegheny and Stateoflennsylvania, have invented a new and useful Improvement in Coke-Oven- Charging Cars, of which the following is a specification.

This invention relates in general to coking plants and has more particular reference to the provision of efiective means for taking care of the smoke incidental to the charging or recharging of a heated coking oven.

In the coking of coal each charge as com pletely coked is pushed from the coking chamber and a succeeding charge is deposited therein immediatey. There is of course a high temperature in the oven cham ber and as the coal is poured in' considerable smoke is evolved which is commonly discharged directly from the charging holes and ascension pipes of the ovens into the open air.

This invention has for a principal object the provision ofsimple-apparatus in a coking plant for carrying ofl this smoke. so that it may be led to the stackof the battery or any other stack or to a smoke consumer; usually it is led into the battery stack where it is discharged atsuch height that the smoke nuisance to labor or vegetation is eliminated.

A further objectof the invention is the provision of a charging apparatus provided with means for accomplishing this result which will be of simple construction and not require a considerable amount of attention in its operation.

A further ob 'ect ofthe invention is the provision of means for taking care of the smoke incidental to charging and recharging without altering in any particular the construction of the coking ovens themselves and with the mere addition tothe stationary equipment of a main for carrying off the smoke delivered by the charging device.

Other objects and advantages of the invention will be apparent as it is better understood from thefollowing description when considered in connection with the accompanying drawing illustrating a preferred embodiment thereof.

On the drawing,

Figure 1 is a vertical section through top of a coking chamber showing a charging truck or car in elevation;

Fig. 2 is a top plan view of the car shown 1n Fig. l; and

Fig. 3 is aside elevation of the car with the tops of the series of coking chambers shown in section.

For the purpose of illustrating my invention I have shown on the drawing a battery of coking. ovens composed of individual coking chambers 11 of certain preferred construction. In accordance with the general practice each of these chambers has a series or set of openings 12 in its top, said openings being normally closed by the usual lids At one side, preferably the or covers. pusher side, the apparatus generally designated at 18,14 is provided to carry off the coke oven gas to a byproduct plant for storage and for distribution.

In accordance with my present invention a smoke main 15 is mounted on suitable supports 16 along the other side of the battery and this smoke main is provided with an inlet 0 ening 17 opposite each coking chamber. 11 the present instance it is intended that the smoke incidental to the recharging operation will be conveyed from the .coking chamber being charged to the smoke main by way of the openings 12 and the charging truck or car which is depositing a new charge of coal. Two tracks 18 extend along the top of the battery and across the several coking chambers and on these tracks the charging truck is propelled in any suitable manncr.

The-truck comprises a framework, built of structural metal. a base consisting of channel irons 19 and I-beams 21. The base is supported upon wheels 22 journaled in suitable bearing brackets 23 from the I-beams 21.

The charging car or truck in the present instance is provided with four hoppers 24 of general funnel shape and carried in a supportlng framework 25 of angle iron or other structural metal construction. The bottoms at its bottom by a slide 26 beneath which is located a chute 27, about the bottom of which -is provided an extensible sleeve 28 adapted to be projected into an approprlate opening 12 of the coking chamber. When a slide 26 is moved from closed positionthe charge in the corresponding hopper is emptied through the chute into the coking chamcarried upon the truck and from it branches 31 extend into the-sides of the chutes. It is intended that the hoppers be opened severally or at least that they be not all opened alteration of the coke ovens themselves and through the mere provision of suitable appliances upon the charging car and a smoke stood from the foregoing description, and it will be apparent that various changes may be made in the'form, construction and arrangement of the parts without departing from the spirit and scope of the invention. or sacrificingits most material advantages, the

form hereinbefore described being merely a preferred embodiment thereof.

at the same time, and to this end individual controlling means are provided for each hopper.. This control comprises an operating lever 32 for each hopper pivoted at 33 on the'truck frame and link 34 connected to said lever and .to a secondlever 35 also pivoted on the truck frame, at 36, which'second lever is connected by a link 37 with the slide 26. The several levers 32 are disposed in "a cab 38 in which the attendant in control of the truck stands. Thiscab 38 is centrally located and the arms of levers 32 are offset, being rigidly fastened on pivotally mounted fulcrum shafts 39 so that operation of the levers results in a direct pull on the slides The control for the extension sleeves 28 is tion also mounted in the cab and this consists of a pedal or lever 41 pivoted. at 42 and connected by a link 43 with the arm 44 of "a crossbar or fulcrum 45' having individual arms 46 connected to lifting yeye bolts on the sleeves 28, the arms 44 and 46 with the universal bar forming in effect a mul- 1 tiple arm bell crank lever. v 40 The flue 29 has an extension adapted for 7 direct connection into the inlets 17 of the smokemain'15; This connectionconsists of a pipe 47 pivotally connected at48 with the v end of the main flue member. The outer end of the pipe 47 is turned down at 49 so that it may make proper connection into the inlets 17.

The action of recharging the coking chambers consists briefly in connecting the smoke flue with the smoke main and lowering the sleeves 28' and then the manipulation of the sliding levers, the inrush'of coal from one or moreof the hoppers causes the smoketo be delivered out of the other charging openings into the smoke flne'29-and if the hoppers are singly manipulated there are available three distributing opcnings throughout the rechargingoperation, it being understood that the corresponding hopper slides are closed as soon as each hopper is emptied.

It will be obvious that the smoke incidental to recharging the coking chambers is carried off for proper disposition, where the present embodiment of the invention is employed, withoutrequiring any reforming or mg ovens,

I claim:
