SPRING-DISK VALVE.
Specification of Letters Patent.
Patented Feb. 27, 1906.
Application filed April 13, 1905- Serial No. 255,457.
7 with ease and provide for easy removalof the valve and prevent its sticking on its seat; to improve the means for making good contact between the valve and seat, and to provide for firmer seating without exerting too much pressure on the stem to make a readily renewable seating part and to avoid the necessity of very accurate grinding of the contact surfaces. These and other advantages to hereinafter appear, are gained by the construction illustrated in preferred forms in the accompanying drawings, wherein Figure 1 is a central vertical section of a common globe valve having my improvements therein, and
Figures 2 and 3 are similar sections of fragmentary parts showing respectively two modified forms of the spring disk and its seat.
The casing A is provided with the usual hood 4 and packing box 5, through which the screw stem 6 operates as ordinarily. The valve stem 6 in Figure 1 has a non-rotating removable head 7 to which is attached the sprin disk 8 made in a concave or partispherical form and held on the head 7 by a nut 9. This disk normally is slightly smaller in diameter than the valve seat, which is in the,form of a groove 10 in the partition-11, as shown. The disk is preferably of softer metal than the seat and may conveniently be made of sheet copper. As the valve stem descends the disk 8 will easily enter the seating groove and when it strikes the bottom will be laterally spread by further pressure downward on the disk 8 has'a rounded ed e and engages a the rounded seating groove 10 In all forms the close contact is made by the expansion of the disk and its vertical resilience, whereby it may accommodate itself to the form of the seat. It will be seen that there is considerable room for wear of the disk and that it may be readil renewed when desired. Other advantages 0 the device will readily occur to those familiar with such valves.
Having thils described my invention and illustrated its use, what I claim as new, and desire to secukpc by Letters Patent, is the following:
1. n a valve the combination with a valve seat comprising a groove havin a flat surface and a circumferential su ace, and a valve having means to expand laterally against the circumferential surface when pressed downward upon the flat surface of the seat.
2. In a valve the combination of a spring disk valve of concaved form anll made of soft metal, and a valve seat of hard metal having means to engage the edges of the disk on several surfaces thereof, whereby the downward pressure of the disk on the seat will cause it to spread radially to engage the seat'in both vertical and horizontal direction, substantially as described.
3. The combination of a valve seat comprising a circumferential groove, and a valve comprising a concave disk, the stem of the valve being attached to the higher part or center of the disk, and adapted to spread the disk at its edges by downward pressure on the disk, so that it engages two surfaces of the groove.
4. In a valve the combination with a valve seat comprising a circumferential groove, and a parti-spherical valve disk of softer metal, adapted to be spread bythe pressure thereon and engage the seating groove on two of its surfaces, substantially as described.
In testimony hereof I have hereunder signed my name in the presence of the two subscribed witnesses.
JAMES T. HAYDEN.
