Continuation of application Serial No. 780,89 8, filed July 24., 1913. This application filed October 29, 1914; Scria1No.869,231.

To all whom it may concern Be it known that I, HEXRY A. CARPENTER, a citizen of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Valve. l\lechanism for Gas-Retorts, of which the following is "a specification.

The present invention relates to improvements in valve mechanism. for gas retorts, being a continuation in part, of that filed by me July 24, 1913, Serial Number 780,898,

the present disclosure including certain additional amplifying features.

The general invention disclosed herein and in said parent application pertain more particularly to apparatus in which the mouth-pieces are adapted to connect with the stand-pipe, the latter serving as a conduit for a plurality of separate retorts. In practice, it is desirable that communication between the mouth-piece and stand-pipe be generally open, a closure of such communication being had when it is desirable to open the mouth-piece lid for any purpose; the

fa result, the seat' for the valve which controls the passage-way tends to clog up with consequent liability of an imperfect seating of the valve, and this is especially the case where the valve itself is located directly in the path of travel. of the gas to or through the passage-Way.

The present invention aims to overcome these objections, together with others hereinafter indicated, and has for its objects, the provision of a valve mechanism which is simple and efficient in operation, durable in construction, and which will be effective in retaining the valve and its seat in condition to provide for maximum efficiency of the retort apparatus.

' in connection with a stand-pipe, and provided with valve mechanism, the View showing portions of retort closure means; Fig.

2 is a detail view partly in section showing the passage-way between the mouth-piece and the stand-pipe, with the valve in position'therein; Fig. 3 is a view similar to Fig. 1 showing the valve in a' different position and showing. additional means for holding the valve to its seat; Fig. l is a front elevation of parts shown in Fig. 3, and showing different positions of the valve; Fig.

5 is an end elevation looking in the direction of the arrow in Fig. 4; and Fig. 6 is a detail sectional view showing additional leakage prevention means, the section being taken on line 66 of Fig. 5. Figs. 1 and 2 of the drawings are disclosures of views of the above-identified application, these views disclosing the general features of the present application, these features being first described.

1 designates a mouth-piece designed to be connected with a stand-pipe 2, the latter being provided with openings 8 adapted to cotiperate with outlet passages or nozzles 4 of the mouth-piece to form a passage-way from the retort to the stand-pipe. Preferably, the stand-pipe is'adapted to be located between adjacent rows of mouth-pieces, the latter being connected to the stand-pipe on opposite sides. The nozzles are each provided with a seat 5 at the outlet to the passage-way, and the nozzle and stand-pipe have complemental faces adapted to engage to provide for an efficient joint connection therebetween.

The communication between the mouth piece and the stand-pipe is controlled by means of valve mechanism which is so positioned and arranged that when the passage-way is open, the valve will be spaced therefrom, and preferably located at a point out of proximity with the outlet to the passage-way, thereby tending to prevent deposits thereon suflicient to affect the seating of the valve; in addition, the valve structure is so formed as to tend to clear the seat as well as the valve from such deposits during the seating movement that the actual closing may provide against material leakage.

A preferred way of producing-the result is shown in the drawings, in which the valvestem is in'the form of a bent arm 8, a portion of which is in the form of a shaft 10 projecting outwardly from the mouth-piece and having its bearing in a casing 11, the outer end of the shaft 10 being preferably shaped, as at 12, to permit a tool, not shown, to be placed thereon and by means of which the shaft 10 and the arm 8 may be oscillated with the shaft as the axis of oscillation, the shaft axis extending at substantial right angles to the axis of thepassage-way.

As shown in Fig. 1, the inner portion of the arm is bent at an angle with the shaft, and said arm, as shown in Fig.4, has its inner end adapted to carry the valve 7 with a ball and socket joint connection, the valve 7 being preferablylof the ball 'type. As shown in Fig. 2, this particular arrangement is such that the valve 7, in its movements toward and from its seat, describes an 'arcuate path which places the valve, when the passageway. is open for operation, below and to one side of the passage-way the result being that while the valve itself isJVithin the mouth-piece, it is positioned somewhat out of the direct path of the gas into and through the passage-wayg'and therefore less liable to the deposit of impurities thereon. As thevalve seat, however, is located in immediate proximity to such path, it is subjected to such deposits; hence, when the valve is to be closed, it isdesirable to provide for eliminating these deposits as much as possible in order that the valve may be seated substantially free from leakage; This action is provided by the particular movement of the valve support and the ball and socket connection of valve 7 and arm 8, this connection being in the nature of a universal Joint. 3

As will be readily understood, the valve 7 is substantially free to move on the ball 9 during travel to and from its closing position, the result being that as the valve approaches its seat, any change in position,

made during such movement will be corrected by contact with the seat; Such correction'obviously provides a relative movement between valve and seat and thus dis- I lodges the impurities or otherwise destroys stantiallv free from leakaee.

of the valvepin ordermembers 31 and 31 their ability to prevent accurate fitting of valve and seat so that when the valve becomes actually seated, the joint will be sub- In roviding this result, not only is the shape of the support important, but also the shape of the valve itself, the seating facepf the latter eing somewhat spherical, so that as it ape proachesits seat, it will practically fit thereon even"though it is not accurately positioned on its support, tending to accommodate for variations in accumulations as it approaches its seating position. As the movement, however, continues, this condition is righted by a correction in the position of the valve, causing a movement of its seating face in such manner as to tend to remove accumulation by abrasion. Since the valve is loosely mounted, it will be readily understood that the liability of successive position corrections bringing precisely the same parts of the valve and seat into contact is very small, so that there is a tendency to a self-cleaning which will retain the valve seat and valve comparatively clear of in connection with the use of tension means, presently described, for retaining the valve in its closed position, such tension means tending to force the position-changingeffeet.

As shown in Figs. 1 and 2, the shaft 10 is provided with a stop member 14: which in the general arrangement of said prior appll cation, cotiperates with the door operating mechanism to prevent movements of the latter to open the door prior to the closing of the valve 7.' ,In the-amplification of the general invention set forth herein, this mem her is given the additional function of positively retaining the valve in its closed position, this being provided by the use of a member 30 ha ing the general configuration shown in Figs. 3, 4 and 5, this member being secured to the mouth-piece and ha'vin its free end located in the path of trav l of the toe of the, member 14, such free end being bent at a point where the toe will pass slightly beyond the bending line when the valve is seated, the result being that said 115 member 30 willact as a retaining means for the valve to prevent accidental valve opening. The member 30 may, if desired, be formed of resilient material, thereby plac ing the closed valve under a tension action. 12

A further amplification is disclosed in Fig. 6, in which the shaft 10 is shown as mounted in a specially designed structure for the purpose of rendering the joint gas tight. This is provided by employing two 125 having opposing faces, complemental on approximately spherical lines, the member 31 being carried by a threaded tubular member 32 mounted in the mouth-piece, the member 31 being carried 130 iaeaiea by the shaft 10. The shaft 10 extends through the tubular member and has itsouter end provided with holding means which may be in the form of a sleeve 38 keyed to the shaft, or which may be the member-'14 and nut 13 of the remaining figures. In either case, an annular abutment is'provided at the outer end of the member 32 with which'a spring as is adapted to contact,-the opposite end of the spring contacting with an internal shoulder 32 of the member 32, this arrangement placing the shaft 10 under tension in a direction to hold the opposing faces of the members 31 and 31 leakage-proof, and still permit of the swinging movements of the valve through the oscillation of the shaft 10, the members 31 and 31*"- practically forming a universal joint at this point.

As will be seen, the arrangement of parts disclosed herein will provide for maximum efliciency in preventing leakage, the several features cooperating in this respect. For instance, the forming of the valve semispherical or ball-shape and mounting it on an arm adapted to swing to and from position through an arc, with a ball and socket mounting, automatically provides for an action which will tend to eliminate the efiect oi the impurities deposit on the valve seat. Another effect is to locate the valve, in open position, out of the direct path of travel 01' the gas through the passage-way and thereby reduce the liability of the impurities depositing upon the valve itself. Furthermore, by mounting the shaft 10 with its axis extending at substantially right angles to the axis of the passage-way, the general construction is simplified and manipulation of the valve to provide the swinging movement to and from closing position rendered possible with minimum leakage and by the use of ordinary actuating means.

While I have herein shown and described a preferred form of construction, it will be readily understood that variations or modifications thereof may be required or desired to meet the various exigencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifi cations as may be required. to meet such conditions in so far as the same may fall within the spirit and scope of the invention as expressed. in the accompanying claims.
