Specification of Letters Patent.

I Patented May 2, 1922.

' Application filed anu r 1920. Serial No. 352,529.

Be it known that 1,. Louis WILPUTTE, a citizen of the United States, and a resident of New Rochelle, in the county off-Westchester and State of New York, have invented certain new and useful Improvements in Standpipe Connections, of which the following is a specification.

The general object of my present invention is to provide an improved valve arrangement especially devised for use in the stand pipe connections from. the coking chambers to the gas collecting main of. a by-product coke oven plant.

The various features of novelty which characterize my invention are pointed out with. particularity in the claims annexed to and forming a part of this specification.-

: of a by-product coke oven battery;

Fig. 2 is a plan of a portion of the apparatus shown in Fig. 1; v

Fig. '3 is a sectional elevation. of the apparatus shown in Fig. 2; and

Fig. 4 .is a plan on a small scale of a portion of the coke oven battery. I

In the drawings A represents the coking chambers of a by-product coke oven battery AA of a well-known type, and B the stand pipe connections, one from each chamber A to the usual gas collectingmain O which extends longitudinally of the oven battery AA and transversely of the individual coking' chambers A. Each of the stand pipe connections B, as shown, comprisesa portion extending vertically upward from the oven structure, and. a horizontal portion which extends over the collecting main and is provided with a port B inits under side opening into the collecting main through the top wall of the latter. Associated with the port B is a valve D in the form of a disc'which may well be made of iron or steel plate,and is riveted or otherwise secured to the lower end of a valve stem D which passes upward through a removable head B normally closing an opening in the stand pipe connection B above the port B. The valve mounting thus provided for each valve D permits the movement of the valve back and forth between its open position shown in dotted lines in Figs. 1 and 3, and its closed positionshown in full lines in Fig. 1. In its open position, each valve D- is located in the collecting main C at such a distance below the top wall of the latter that it does not impede the flow of gas into the main from the corresponding stand pipe. In its closed position, each valve D lies in the up- .per portlon of the port B which is also the most restricted portion of theport B when the latter is of the preferred tapered or conical form shown in the drawing. The valve disc D need not fit closely in the portion of the port B occupied by the valve in its closed position, and I expect, in practice, to make each valve disc D a sixteenth of an inch or so less in diameter than the portion able jack or other mechanism may be employed for raising and lowering the valve. For example, .as shown, a. carriage E, run ning on rails C and G fixed to the'side of the main C, may beprovided with a hoisting.

winch E for raising and lowering a hook E adapted to engagea pinor crossbar D connected to the upper end of the valve stem D.

Means are provided for sprayingtar o a mixture of tar and ammonia liquor into the collecting main throughueach port B. For this purpose, I provide in the construction shown, a tar supply pipe F running alongside the main C and provided with a branch F for each port B Advantageously each branch F is connected-into a T G which is threaded into a port B formed in the wall of the corresponding port B. The port B opens into the port B justbelow the valve D when the latter is in its-closed. position,

and the port B is downwardly inclined (see Fig. 3) so that, with the valve in its open position, the liquid discharged through each port B will washthe upper side of the corresponding valve D. The T G is provided with a' eleanout opening, normally closed by .a plug G. V Y

In the practical intended use of the apparatus shown, the standpipe connections from the various coking chambers of the coke oven battery are in free communication with the collecting main C at all times except that at the end of each coking operation. in

a coking chamber A, of sixteen to twenty-1 bottom portion of the collecting main is largely prevented by maintaining a constant flow of a flushing liquid stream of tar or tar and ammonialiquor through the main. All the tar or tar and ammonia liquor required for flushing the main C may be supplied by the branches F, or a part of this liquid may be injected into the end of the main by a branch F as shown in Fig. 4. 15" represents the pipe through which the flushing liquid. is withdrawn.

With the novel Iarrangement disclosed each valve D, when in its open position, is constantly bathed in the flushing liquid discharged by "the corresponding port B and eventually' formin a part of the flushing liquid stream flowing through the main C. The valves D are thus protected against the deposit of pitch and carbon on them while in their open positions. Each time a valve D is moved into its closed position it cuts through the deposit of pitch and carbonon the wall of the ,port B, thus effectually cleaning the latter, and at the same time cuts a seat for itself fitting perfectly about the periphery ofthe.

valve. The material thus cut from the wall of the port B and collecting above. the valve D may be removed when the valve is in its closed position by a tool or impiement inserted through the clean-outdoor In normal operation each port B will be sealed when the correspond ng valve D is moved into its closed position by the pitch and carbon deposit between the valve and the metallic wall of the port B. y

In any case in which the pitch and'carbon deposit does not provide a gas-tight seal, such a seal is insured by the liquid, though somewhat viscous, tar or tar and ammonia liquor layer which the valve D will carry on its upper-side; A s the valve'D moves into its closed position it first approaches and then passes-the tar inlet 15 and in consequence a considerable amount of tar will be reaches its close position; This tar will carried'on the to of the valve D when it run into and seal any open joint which may exist, in practice, between the Q riphery of I Y the valve andthe deposit coate wall of the port B It should be explained that the difference between the gas pressure in the main C and the-pressure above the valves D.

ing stand pipes, I preferably form an inclined rim B about the up er margin of each "port B. Those skilled -1n the art will know that each standpipe B is put in free communication with the atmosphere by the.

opening of its door B during practically the entire period in which the corresponding valve D is closed.

The truck E may be moved len thwise of the battery on the rails C and the winch hook E in position for engagement with first-one and then another of the valve stems D as the various coking chambers are discharged and recharged in regular turn. Should a valve D stick in its seat when the timecomesto open it, the valve may be forced to itsopen position by hammer blows on the upper end ofthe valve stem D.

Theimproved valve arrangement possesses numerous important advantageous characteristics from a practical standpoint. It isrelatively inexpensive to construct as the parts are few, light in weight and require a minimum of machining. In case the valve proper becomes bent or otherwise injured, it may be replaced easily and at a very small expense. If necessary or desirable each valve D may be rotated in its seat to facilitate the removal through the cleanout door 13" of pitch and carbin deposits out from the wall of the port B in'the movement of the valve into its closed position}.

The provisions described for delivering a jet of tar or tar'and ammonia liquor on the top of each valve disc when in its open position not only keep the valve discs clean an provide them with sealing material when closed, but also form simple and effective means for supplying the main'C with the necessary flushing liquid. It is never necessary in normal operation to interru t the discharges through the various ports While in accordancewith the rovisions of the statutes I have illustrate and described the best form of my invention now 6* to bring.

.mme cases certain features of my invention may be used' to advantage without a corresponding use of other features.

Having now described my invention, what'I claim as new and desire' to secure by Letters Patent, is: I
