J. ELLBERG ET AL VALVE, cocx, AND THE LIKE NITNESS Filed Jan. 18, 1929 2 sheets-sheet 2v Patented Dec. 31, 1929 UNITED STATES PATENTy OFFICE JOHN ELLBERG, OF NEW YGRK, ANI) MAG-NUS CRONWALL, F BROOKLYN, NEW YORK VALVE, cocx, AND THE LIKE -Application led January 18, 1929. Serial No. 333,387.

The present invention resides in an improved construction and arrangement of parts in valves, cocks, and the like, by means of which devices of this character may be simply and economically manufactured; rendered effective in service; and made to respond uniformly to the light pressure of a manipulators hand.

One purpose of our invention is to provide means of improved construction whereby binding effects on the valve stem, to permit freer movements of the valve and operating parts, to produce a. more perfect seating of the valve, and to improve the wearing qualities of said valve.

Other and more specific purposes of our invention will be understood from the' specication, the constructional features relating thereto being recited in the appended claim and shown on the accompanying drawings.'

In the drawings'which show several emlbodiments of our in v'ention,`

Vl4`igu're 6 is an axial section of another typey of valve cock constructed in accordance with the principles of our invention, parts being broken away and parts shown in elevation.

Figure 7 is a view similar to Figure l and showing a modified form of the valve cock shown therein.

Figure 8 shows a modified form of the valve proper shown in Figure 4.

eferring to the embodiment of our invention shown in Figures 1, 2 and 3, the Valve housing l is provided withia cap or bonnet 2, a iange 3 of said cap or bonnet being threaded at 4 to the upper neck portion 13 of the housing 1. Said housing 1 is provided with a base flange or bib 5 below which extends a threaded neck 6 provided with an inlet passage 7 leading to a port opening 8 which is controlled by a conical valve 9 seated on a frusto-conical seat 10. Valve 9 is providedwith a port 11 Whichis adapted to be moved into and out of registry with the port opening 8 and thus to control the discharge of water from the passage 7 through a discharge outlet 12. Interposed between the threaded necky 13 of housing 1 andthe lower edge of bonnet 2 is a seating washer or partition 141 which separates the valve chamber 15 from a disk-seating chamber 16. -The washerl or partition 14 is provided with a central opening 17 through which projects a square stemsection 17 carried by the valve 9. Bearing on the upper surface of partition 14 is a seating disk 18 which is mounted in the enlarged recessed end 19 of a hollow stem section 20 which is closed at `the top and is provided with an axial socket or chamber 21 of rectangular cross-section for movably but nonrotatabl engaging the Square stem-section 17 on t e valvecock 9. Ahelical compression spring 22 is interposed between the topwall of chamber 21 and the upper end of the squared extremity 17 for yieldably pressing the valve cock 9 vinto contact with its seat 10. Mounted in a recessed disk 23 is aI seating disk 24 of suitable composition, said recessed disk bein carried by a stem section-25 which is oscil atably mounted in the top wall 26 of the cap or bonnet 2. The iuid-tight joint between seating disk 21 and the inner surface of top wall 26 may be enhanced by the provision of a circular spur 26a on the latter which sov works in al corresponding annular groove 24'L in the upper surface of the former. Interposed between the axially spaced flanges or disks 19 and 23 is a helical compression spring 27 which exerts a yieldable pressure for pressing the seating disks 18 and 24 into close contact with the finished surfaces of washer 14 and top wall 26. Surmounting thestem 25 is a handle 28 provided with a square socket 29 to fit the reduced square section 30 of stem 25. It will be understood from this description that whenever the handle 28 is shifted in one direction or the other, the 'uppermost stem-section 25, intermediate stem-section 20, and the bottommost stem-section 17 will be moved together on their common axis to open or close thevvalve cock 9. A screw 31 retains ,the handle in position on the reduced portion 30 of the uppermost stem-section 25.

Referring now -to the embodiment of our invention shown in Figure 4, an angular vhousing 32 is provided with an interiorly threaded neck 33 toreceive an inlet pipe (not shown)` and an exteriorly threaded neck 34, which may be connectedto a service pipe (not shown). An inlet chamber 35 opens .upwardly through an annular valve seat 36 through which the fiow is controlled by means of a valve comprising a recessed cap 37 and a seating disk or washer`38 secured thereto by a nut 39 carried by a threaded stem 40. An inwardlyl defiected flange 41 on the cap member 37 articulately engages the rounded lower extremity l42 of a reduced neck 43 which is rigid with a'valve-stem section 44 of rectangular cross-section. The valve-stem section 44 projects into a rectangular recess or socket 45 in a hollow stem section 46 which carries a recessed disk 47 for the reception of a composition seating disk 48. The disk 48 bears on the finished upper surface of the partition or washer'14, the valve stem section 44 being presented through the opening 17 in the washer 14. The valve stem section 46 is provided with a square end 49 which fits a recess or socket 50 of rectangular cross-sec-Y tion which is formed within the valve stem section 51. This valve stem section 46 is provided with a iange or recessed disk 52 for the reception of a ,seating disk 53. The valve stem sect-ion 51 carries a. hande 54 which, when shifted, causes the valve 38to be lifted from its seat 36 by means of a threaded enlargement 55 which screws into a threaded socket 56-formed in the inner wall of a neck portion 57 of the valve housing 32. A compression s ring 58, which is interposed be.- tween the anges or recessed disks 47 and 52, maintains the seating disks 48 and 51 in contact with thefinished surfaces with which disk 14 and the inner top wall of a cap 59 are provided. Said cap-59 screws onto the exteriorly threaded wall of the neck portion 57. The seating disk-53 is preferably formed with an annular groove 53* into which fits la circular spur 59n which is presented inwardly from the inner top wall of cap 59. As shown in Figure 8, the valve with its seating disk may be constructed in a single piece 6() with a raised pad 60 provided with a finished machined surface adapted to seat against the annular valve seat 36 shown in Figure 4.

Referring now to the embodiment of our invention shown in Figure 6, an angular valve housing 61 is provided with an inverted frusto-conical seat 62 which opens upwardly through a threaded neck 63. An inverted frusto-conical valve-cock 64, which is made hollow, is open at its lower contracted end to admit fluid entering through a threaded inlet neck 65. A port opening 65L in the lateral wall of the hollow valve-cock, is adapted to permit the discharge of fluid through a threaded outlet neck 66 whenever said valvecock is open. Said valve-cock is preferably provided with a closed flat top wall 67 which is exposed on its inner surface to the pressure of the entering fluid and on its outer surface is slidably engaged by a washer or partition 68 which is clamped in position on the upper extremity of threaded neck 63 by means o1 an annular shoulder 69 formed in the inner wall of a cap 70, said cap being screwed onto the threaded neck 63. A central opening in the washer or partition 68 permits the oscillation of a square stem-section 71 which is integral with the valve-cock and fits into the square socket 72 of a hollow stem section 73 which is closed at the top. Said stem section 73 carries a seating disk 74 forming a close seal with the finished upper surface of washer orpartition 68 under the pressure of a compression spring 75 which is interposed between the flanged lower ends 73 and 7 6a of stem section 73 and an uppermost stem section 76 respectively. TheV recessed flange 7 6 carries a seating disk 77 which is pressed against the finished inner surface of the top wall of cap 70. A rectangular reduced end portion 7 3* of the hollow stem-section 73 fits into a square socket 76b in the uppermost stem section 76 which carries a wrench or handle 78. A compression spring 79 intervposed between the square stem section 71 and closed top wall of the hollow stem-section 73 is employed to counteract the Huid pressure against the inner top wall of valve cock 64 to any desired degree.

In the embodiment of our invention shown in Figure 7, a form of valve-cock of somewhat similar construction to that shown in Figure 1 but arranged in an angular globe housing such as that shown in Figure 4 may be adapted for the control of fluids in pipes or conduits of relatively lar e cross-section. For this purpose, an angu ar globe valve housing 80 which is provided with an interiorly threaded inlet neck 81 of relatively large internal cross-section, is provided with v a baille 82 extending across the direct line of flow of the entering fluid and deflecting said fluid into a laterally widened channel leading to a port opening 83 in a partition Wall 84 which extends part way around an inverted frusta-conical valve head 85. Extending throughl the valve head 85 is a circular opening 8G which may be moved intoA and out of coaxial alinement with port opening 83 and the discharge outlet'ST of the valve housing. It will be understood from this description thata large volume of water may be thus controlled by a valve cock by the sectional f stem connections described above under balanced fluid pressure and under a comparatively light axial pressure impressed upon the valve cock. y

According to our improved valve and valve-cock operating device, it is readily seen that an effective luid-tight'seal may bc maintained between the oppositely-presented seating disks and the finished bearing surfaces against which they press. All packing is thus avoided together with the undesirable binding and warping effects produced by the packings so commonly employed.

The combination with a valve housing provided with a cap threaded thereto, o'l a partition wall clamped to said valve housing by said cap, said partition wall being provided with a central opening, a valve in said valve housing, a valve-operating stem section extending through the opening in said partition wall, a seating disk provided with a hand-operated stern section rotatably mounted in the outer wall of said cap and rotatably abutting against the linner wall thereof, and a second seating disk rotatably abutting against said partition and having a stem section interengaging with the first-mentioned seating disk; said hand-operated stem section being non-rotatably connected to the secondmentioned seating disk.y
