VALVE.

To all'wh om it may concern:

Be it known that I, JOHN a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Valves, of which the fol' lowing is'specification. i

It" is the obj ect of the presentinventionto provide a valve suitable for use in faucets, ball cocksan d the like and havingspecial means for protecting against stoppage and injury to the valve Whenl'fir st installed also havingits parts so shaped and related as to be easily adjustable to different water pressures, theseparts also being so shaped that hammering is in largefmeasure prevented and reliable'and eflicient operatlou gages therewith and has ts upper edge insured.

hen faucets and stop-eocksjfor water closet'sare first installedin new buildings, they are subjected to severetreatment, owing to the action of steel and iron; chips, rust and red lead in the, water pipes, for when the water is first turned on, this; dirt comes throughto the valve and: isv very likely to lodge on the valve seat, thereby'preventing; the'valve from closing and making it necesiy for r r 0, dtegh theffi i ureanrl In new 'buildin s,

' is to work,

remove the objections 1 these stoppages are so frequentthat faucets have to be taken off repeatedly, sometimes several times a day, with the result that when the building is completed and ready for occupancy, the faucets have beenfbadly damaged and marked up by the plumbers wrenches, if notdestroyecl entirely.

According to the present invention, the valve seat is protected from foreign matter and the faucet or other structure, of which the valve is a part, is so constructed that a heavy collection of sediment in the pipes can be removed without injury to the faucet.

In the drawings forming a part of the present specification,

Figure 1 is a sectional elevation through a faucet embodying the novel features of the present invention.

Fig. 2 is a perspective view of the valve and valve stem. 7

Fig. 3 is a perspective view of the valve spring and its perforated plate.

In the embodiment illustrated in the drawings, the valve stem 1 is in the form of a straight rod unthreaded at its upper end and hearing at its lower end a shoulder 2 H. JOHNSON,

against which is clamped a packing ring 3 supported within a cap/l which is threaded onto the lower end of rod 1. The lower part of cap 4 extends downward as a lug 5, flattened on each side to serve as wrench seats. This lug 5 normally extends down into the upper end of a helically coile'd spring 6, wl ch carries on its lower end and preferably soldered thereto, a perforated di sk'7. Th-is'disk normally fits von a shoulder in the base casting 8 of the faucet or other structure, which the valve is a part and serves as a strainer to hold back any iron chips orfiakes and any large pieces of red lead or the like. 7

The upper edge of casting 8 is provided with a threadedfiange 9. and a nut 10 encupped' inward to form anannular flange 11.

The valve seat of the embodiment here illustrated is part ofa cup member 12, which has its'outer wall tapered, shown, to fit within the flange 9 of the base casting 8. The inner diameter of thiscup 1nember 12 is only slightly larger than 'the outer diameter of the cap 4, say a thirtyesecond of an inch on: each side, or withji st enough space to give a suitable water-way for the particular water pressure under which the faucet i For unusually high pressures, such as are encountered on thelowerfloor oftallbuildings, a closer fit may be provided between cap14 and cup 12 torc'ut down the pressure ofwater delivered at the spout of the faucet. An annular rib 13 carried at the base Of, the cup is positioned to contact with the packing ring 3, thereby forming a water tight seal under the combined action of spring 6 and the water pressure on the lower face of the cap 4. The central outlet 14 of the cup member 12 is so nearly the same diameter as shoulder 2 on the valve stem, that the latter enters the outlet 14 with a snug fit.

The main casting 15 of the faucet is threaded to the upper end of the cupped member and together with that member forms a chamber, in which the flange 11 of nut 10 may freely turn around when that nut is being unscrewed from the base member 8. This main casting may have a partition 16 serving to guide the valve stem 1 and the upper portions of the faucet, includ- I will be caught by the perforated plate 7'and ing actuated by asuitable handle 19 to force that valve stem downward when water is to be drawn off through the faucet. The downward movement of the valve 3 downward in cup member 12 far enough to permit ready flow of water upward through the perforated plate? and past the. valve outward to the discharge spout.

Any coarse sediment carried in the'water cannot get through to damage the valve seat. Should a, large particle of sediment be thrown. violently into contact with the strainer plate 7, the latter will yield under the influence of the spring so as to prevent damage to the strainer. When the handle 19 is released, the water pressure acting in conjunction with the spring 6 will lift the valve upward toward its seat, but the shut-ofi will not occur instantly, because of the back pressure offered to the valve by the Waterstill in the cup member 12 and its outlet 14:. As the valve enters the cup 12 the water then in the valve will checkfurther movements momentarily, or until the water has succeeded in escaping out of the path of the closing valve.

[Because of its fit in the outlet 14:, the pro jection 2' also serves ,in checking the upward movementofthe valve and assists in protecting the mechanism from hammering when the valve closes.

WVith the, structure here disclosed, even though the dirt in the pipes of the newbuilding may interfere with the faucet, as by ,clogging plate 7, so that water cannot be drawn off, this foreign matter, including the iron chips will not get in on the valve seat and will notprevent the valve from closing. To clean the faucet out, under these con dition s,*it is only necessary to shut ofi the of two witnesses.

water supply, unscrew nut 10, then lift off from the base member-8, all of thestructure, includingcoiledspring 6 and its attached perforated disk 7 whereupon the Valve can be pulled down out of the main casting 15 for inspection and repair. If, desired, the stem 1 will. carry-cape and its packing ring faucet can be put back without its valve and spring and the water then turned on to blow out allthese operations of cleaning the c faucet, nut 10 is the only part that needbeunscrewed andthis is large and easily manipulated Although the specific embodiment illustrated in the drawing'sfiis a faucet, 1 contemplate usingthis same valve. structure in ball cocks and other water controlling devices and I contemplate changes in the details of structure a'ndinthearrangement'of parts within. the,scope of the appended claim., ,v I I The combination of a pair of detachably connected conduits, one of said conduits'haw ing a valve seat and a valve therefor, theother conduit having an internal shoulder, a movable 'stralnerin said other condu t and against the shoulder, and a spring disposed i between and exerting pressure 1n OPPOSltG' directions against the strainer and the valve to yieldably maintain the strainer and the valvein their normal positions,the strainer being attached to the spring and removable therewith.
