Application filed March 2-5, 1913. Serial No. 756,652. 7 k

To all whom it may concern Be it known that I, J OHN L. SAUoHnREAU, a citizen of the United States, residing at Spokane,in the county of Spokane and of-valve and has as its principal object the provision of a water valve which may be positively withdrawn from engagementwith its seat before being moved.

A second object resides in the provision of means for scraping the seat of the valve before closing it.

A third object resides in the particular arrangement and combination of parts hereinafter described.

In the accompanying drawings :-Figure 1 is a central vertical sectional view of my improved, valve showing the device closed. Fig. 2 is a view similar to Fig. 1 but showing the device opened. Fig. 3 is a sectional view taken at right angles to Fig. 1, a portion of the device being shown in plan. Fig. 4 is a side elevation looking in the opposite direction from Fig. 1. Fig. 5 is a top plan view of my device. Fig. 6 shows the valve head looking in the direction of Fig. 1. Fig. 7 shows the valve head looking in the opposite direction from Fig. 6. Fig. 8 is a detail of the mechanism included in line 8-8 of Fig. 3. Fig. 9 is a detail of the means used in adjusting the limit of movement of the valve. 7

In the separate views the same part is designated by the same reference character.

Referring more particularly to the drawings, 1 indicates a casing or special casting intended to be inserted into a pipe line. For this purpose the casting 1 is provided with two circular portions such as 2-3, one at each end,.the portions 2 and 3 being provided with flanges such as 4 1 whereby the casting 1 may be connected to the adjoining pipe sections. -'Ihe central portion of the casting 1 is enlarged to provide a chamber 5 within which the valve is mounted. The face of the chamber 5 at one end is of areshaped section as shown at 6, the center of said arc-shapeolsection being at 7, in Fig.

2. The valve 17 is shaped so as to conform, to the curve of the face 6 and, as best shown in Fig. 6, is of generally rectangular elevation. On the closing face of the valve 17 is a packing ring 7 which is attached 'to the face of the valve by removable rings 8 and'9, such pack ng rings being adapted to form a tight oint with the valve seat around inlet aperture 10. The valve 17 is provided with geared teeth 30 on its inner face as shown in'Fig. 7 and a pinion wheel 29is shown wlthin the chamber 5, in Figs. l and 2, as meshing with the teeth 30 for the purpose of swinglng the valve when it is to be opened or closed. As best shown in Fig. 3," the p1n1on 29 is carried by'a shaft which pro ects through the whirl of the chamber 5, into ahollowchamber formed on the outside of the casting 1. On the outer end of this shaft is a gear 28 which meshes with a worm 27, best shown in Fig. 4. Now the w0rm'27 is fastened to a vertically extending shaft 42 at the upper end of which is a handle 26 by which the valve may be operated through the foregoing mechanism. -On the shaft 12 is a nut 41 threaded thereon and slidably mounted in a guide 40 so that it cannot turn. When the shaft -12-is revolved the nut 41 will travel up or down as the case may be on the guide 40 and indicate thereby the position of the valve head. It being understood that the parts 10 and 41 are on the outside and above the chamber 50. However, it will be obvious that the ring of soft packing such as I prefer to use would be quickly abraded if the valve wasto be moved when such packing ring is in close contact" with the face 6. Moreover, to turn, the valve in such a position would require a great deal of power and consequently I provide means for backing the valve away from the face 6 when it is to be moved, and positively forcing it against the valve seat when it is to be closed. a

For the foregoing purpose I so mount the valve 17 that it may be moved toward and away from the face'6 as well as swung from closed toopened position, and the reverse, and this is accomplished by forming the valve head 17 rigid with two arms 16, one on each side thereof, the arms 16 being pivotally connected to a shaft 19 which carries a round bearing block- 20, mounted in a slot 21 which isprovided in a lug'21 which proj ects from the inner face of the chamber 5. Details of'the foregoing are best shown in Fig. 8. The arms 16 are pivoted to links 15, as shown at 18 in Fig. 1, and the opposite ends of the links 15 are provide'dwith apertures which embrace eccentrics such as 14 carried on sub-shaft 13' which projects inwardly to the walls of the casing 1, in the chamber 5. When eccentric 14: is in the position shown in Fig. l-the valve head is forced strongly against the seat so as to. close the valve, but when 14: is turned to the position shown inFig. 2, the valve is witlidrawn from contact with the face 6 allowing it to be swung gently andavoiding damage by means of gears 11 carried at the ends ,of

the shaft 11. The gears llmesh with teeth. on the outer surface of'thesegments 12 which are mounted on the outer ends of the sub-shaft 13. In order to prevent segments 12 from being turned too far, I provide two lugs 37 and 38 which project from the oppo- I site side of the casting 1 and these lugs are provided with set screws andlock nuts as illustrated in Fig. 9, the setscrew in the lugs 37 being set to contact with the outside of the arms 39 of the segments 12 when the eccentrics 14 are in their maximiun-position in one direction and the set screwin lug 38 being set to contact with theinner edge of the same arm when the segment, and conse quently the eccentrics are swung to their maximum desirable limit in the opposite direction. In order to determine whether or not. the valve is actuated from its seat I provide a nut 43, shown in Fig. 5, which operates inv the guide 43 in a manner similar to the nut 4:1 and guide 40. In order to make sure that the valve is not turned except when actuated from the seat I provide a ratchet wheel 25 on the shaft 42 and a dog 23 is provided which is guided in a lug 2a and which is adapted to engage the teeth of the wheel 25 so as to hold the shaft 42 fixed except when withdrawn. The dog 23 is connected to a link 22 which is pivoted in the arm 39 of the segment12, and the link 22 is so designed that the dog 23 cannotbe with drawn from engagement with the wheel 25 until the segment 12 has been moved so as to back the valve away from its seat.

Valves such as I have shown are designed to remain open for long intervals and consequently it is found that often the valve seat is so corroded and dirty that it is impossible to so close the valve as to prevent leakage. In, order to obviate this difliculty I provide a scraping knife 31, which is carried on links 32 which are pivoted at the points 33, said points 33 being coincident with the points 7, previously mentioned as being the center of the arclike surface 6. At the end opposite the scraper the links 32 are pivoted to lugs 36 which project from the inner walls of the chamber 5 above the lugs 21, lugs 36 being shown broken away in Fig. 8. At their outer ends the lugs 36 are turned downwardly as shown in Fig. 2 so as to provide the pivot as aforesaid.v Consequently the scraper 31 always moves in mounted as to always precede the valve in closing, it insures a clean seat therefor. The

.scraper 31 is held against the edge of the valve head 17 by staple-like retainers 35 fwhich, however, permit the relative move- "ment of" the two when the head is-being withdrawn from the face 6.

to the packing. The eccentrics 14 are operated from the handle. 10 shown injFig. 4,.
