. valve open;
Fig. 2 is an end elevation of the same;
Fig. 3 is a vertical section showing the valve closed;
Fig. 4 is a face elevation of the valve;
Fig. 5 is a side elevation of the thrust ring.
Referring to the drawing annexed by reference-characters, 10 designates the valvecasing in which is enclosed a vertically-working gate-valve 11 whose front face 124 is straight and flat and whose rear face is in-. clined downwardly. The upper end of this valve is connected in any suitable manner to means for raising and lowering it; I have shown a rod 14 working through a suitable stuiling-box 15 on the top ofthe valve-chamber and provided with a suitable lever and link arrangement Jfor reciprocating the rod.
The valve-casing is provided on its inletside with an inlet-nipple 16 and on its opposite, outlet-side with an outlet-nipple 17, the outlet-nipple being bolted or otherwise secured to the adjacent side-wall of the valvecasing and having a tubular projection18 which lts in al hole in the adjacent side-wall of the valve-casing. In an annular recess 19 formed in the outlet-nipple is arranged an -expansible coil-spring 20 whose innermost coil projects into the valve-casing and bears against an annular flange 21 formed on a thrust-ring whose inclined face 32 normally bears against the inclined face 13 of the valve, thereby keeping the valve normally pressed against an annular valve-seat 23, this valveseat consisting of a ring pressing against the.l
inner 'face of the adjacent wall of the valvecasing and having an annular extension 24 extending into the inlet-nipple 16.
The gate-valve 11 is provided with a waterpassage 25 which, when the gate is raised, is
. the inner edge of the thrust-ring.
1929. Serial No. 351,765.
4coincident with ithe water-passage through the valve-seat 23 and the thrust-ring, as shown in Fig. l. The thrust-ring is provided with an outwardly-extending tubular extension 26v which loosely fits into the water-passage throughthe outlet-nipple, and in the corner v between this tubular part 26 and the aforesaid iiange'21 is formed a convex enlargement 27 which is adapted to iit into a similarlyshaped concave annular groove formed in The location of the thrust-ring and the manner of supporting it causes the inclined face thereof to constantly press against the adjacent inclined face of the gate 11, to thus normally at all times press the gate against the face of the seat 23,' thereby preventing the accumulation of grit on the gate or the valveseat. To prevent further accumulation of grit on the face 12 of the gate, I provide the same with a recess or depression 28 at a point above the water-passage 25 so that, as shown in Fig. 3, when the gate is pushed downwardly to close the valve, this recess 28 will lie Ycoincident with the water-passage through 7 the valve-seat, whereby whatever collection of sediment there may be will be deposited in this recess, out of the way and thus be prevented from pitting either the Valve-seat or the gate in sliding the gate up and down. The' convex bead 27 on the thrust-ring together with the similarly-shaped. groove in the\out-` let-nipple forms asort of ball-and-socket joint that permits the thrust-ring to have a sort of universal adjustment whether the gate be. open or closed, whereby at` all times the thrust-ring will exert a straight, even thrust 'f against the gate and thus prevent leakage as well as accumulation on the working-face of the ate.
y"at I claim as new is:
U 1. Ina gate-valve structure, a casing hav- `v ing an inlet at one side and an outlet at the other side, a gate lying within the casing and connected with means for raising and lowering it, said gate having a straight working- -ace and also an inclined face at the outlet in the working-face, a valve-seat arranged around the inletmipple, and a spring-actuated thrust-block or ring arranged to have its entire bearing-face press against the inclined face of the gate at the outlet side in its open 5 as well as its closed position.
2. A gate-valve structure embodying a casing having an inlet-nipple at one side and an outlet-nipple at its other side, a gate enclosed within the casing andv having a straight' working-face and a downwardlyinclined rear-face and also a water-passage, a valve-seat at the inlet-side, a rockable thrust-ring at the outlet-side having an inclined face with its entire bearing part bearing against the adjacent inclined faeefo the gate, and a coil-.spring normally pressing this thrust-ring against the gate in its open as well as its closed position.
3. A gate-valve structure embodying a easing having an inlet-nipple at one side and an outlet-nipple at the other side, this outletnipple being provided with an annular recess opening into the valve-casing and also with a concave seat, a gate within the valve-casing and means for raising and lowering it, the
inlet-face of the gate being flat and the outlet-side of the gate being inclined downwardly, a rookable thrust-ring having a tubular extension lying in the aforesaid outlet-nipple and provided with a convex portion Working in said concave groove, and a spring in the aforesaid annular recess normally bearing against said thrust-ring to hold it against the adjacent inclined face of the gate at all times, the face of the thrustring in Contact with the gate being inclined to correspond with the contacting face of the ate. g In testimony whereof I hereunto aiiix my 40 signature.
