SPECIFIQATION forming part of Letters Patent No. 461,359, dated October 13, 1891.
Application filed July 9. 1891. y Serial No. 398,955. (No model.)
To all whom it may' concern:
Be it known that we, GOQDMAN J. MELLIN and WILLIAM H. HENDRICK, residents of St. Louis, Missouri, have jointly made a new and useful Improvement in Hydrants, of which the following is a full, clear, and exact de-` scription.
The improvement relates to the waste mechanism and other parts of the construction, whereby the water from the discharge-pipe is enabled to waste upward from the valvechamber rather than downward through an extension at the lower end of the valve-chamber, as heretofore has been a frequent practice in hydrant-valves, and at the same time` a desirable provision made for the easy unseating and seating of the valve, and all in such a manner as shall permit of the valvestem and parts thereto attached being removed from the valve-chamber, which mayT remain fixed in the hydrant-box, all substan-4 tially as is hereinafter described and claimed,
aidedby the annexed drawings, making partv of this specification, and exhibiting the most desirable mode of carrying out the improvement, and in which- Figure lis a vertical sectional elevation of the valve-chamber and parts thereinv contained, the valve being` seated and the water,
wasting from the discharge-pipe; Fig. 2, a view similar to that of Fig. 1,but showing the valve unseated and the water flowing through the valve-chamber and into the dischargepipe; Fig. 3, a horizontal section on the line seat; G, the valve-stem; G', the valve-rod;
G2, a thimble for connecting the stern and rod; D', the discharge-pipe leading upward from the outlet D, and H a fiat leather washer interposed between the cap B and the upper end of the body B2 of the valve-chamber.
J represents a spool, which encircles the valve-stem within theupper portion of the Said upper portion is larger' valve-chamber. in diameter than the lower portion of the valve-chamber in which the main valve immediately works, and said spool serves not 'only to form an annular space b between the outer surface of said spool and the inner surface of said chamber, and also another annular space b Within said spool and around said valve-stem, but alsov to render said space b smaller in diameter than is said lowerportion.'
and, owing to the describedsize of said spool being sinallerrin diameterv somewhat than the-main valve, the flange 7o of said kcupleather is turned downward. At its upper end the cup-leather is held againt a shoulder lo upon the valve-stem,and said cup-leathers serve partly to facilitate, by reason of the upward action of the main pressure against it, the unseating of the main valve and partly to prevent the water, when the Inain valve is -unseated, from escaping to the waste-outlet,
end of the spool to prevent the escape of Water through the spool from the inlet C.
The valve F. and the cup-leather K are secured to the valve-stem in their described respective positions by lany suitable means. The valve-stem is extended downward, sub- Stantially as shown at G3, to work in an eX- tension b2 of the valve-chamber, and at its lower end said extension is provided with an upturned cup-shaped valve M, which fits the interior of said extension, serving to cut off the passage'of water in that direction, butaiding to balance the main valve and thereby to facilitate the seating thereof, as in other analogous constructions. Said spool J is perforated at j to provide communication between the spaces b and b. A passage D2 leads from the outlet D to the space l). There is a perforation b4 in the shell of the-valvechamber arranged above the level of the upper terminus of the stroke of the main Valve. It enables a small quantity Of water to pass from the inlet C to above the main valve and thereby help to balance it. When the main valve is seated, as in Fig. l, the Water in the discharge-pipe, as indicated by the arrows x, flows through D2 into the space b surrounding the spool .T,vthence through the perforationsj into the space b within said spool, and thence through openings h5 to without the valve-chamber. Said openings b5 are conveniently formed by squaring the valve-rod and adapting it to work in a round Opening in the 'cap of the valve-chamber, substantially as shown. The washer H is perforated to conform to said opening in the valve-chainber cap, and thus to provide suitably for the passage of the waste water, as described. Vhen the main valve is unseated, the cupleather K is above said perforationsj, and the Water is thereby prevented from passing to said Waste-outlet.
Another feature of the construction is the means for holding the valve-chamber in place in the hydrant-box.. The valve-chamber at itsside is provided with or shaped to form ar bracket N, substantially as shown. Said bracket is shown in full lines in Figs. 4 and 5, and is indicated by the broken lines in Figs.
l, 2, and 3. lts preferableform is an upright flange n, connected by means of the web n with the outlet portion of the valve-chamber, and by means of screws n2, passing through perforations n3 in said ange, the bracket is secured to the side a of the hydrant-box, and all in such a manner as to enable the valve-chamber to be securely fixed in position, and so as to provide no obstruction to the escape of thewaste water downward in the hydrant-box. e
It will be noted that by unscrewing the cap B', and which is accomplished by means of the lugs g g engaging' with the lugs h6 h6 when the valve-rod is turned around, all of the parts Within the valve-chamber can be removed therefrom, and by reversing the Operation be replaced within the valve-chamber.
We claiml. The combination of the va1ve-chamber having the inlet, the outlet, and the main valve-seat, and perforated at D2, as described, with the valve-stem, main valve, cup-leather K, and spool, said spool being perforated and at its upper ends packed, as described, said spool being arranged in the upper part of the valve-chamber above the upper limit of the stroke of the main valve and said pei'- foration B2 leading from said outlet to the space surrounding said spool and said cupleather K Working within said spool, substantially as set forth.
2. The valve-chamber having the outlet, the spaces b h', connected as described and 'arranged above the upper limit of theistroke of the main valve, and the passage establishing communication between said outlet and said outer space h, in combination with the valve-stem provided with the cup-leather K, which works within said` space b and prevents the water, when the main valve is unseated, from passing to the waste-outlet, substantially as described.
3. The combination of the valve-chamber having the main valve-seat, the inlet, outlet, and passage D2, as described, the valve-rod, the main valve, the cup-leather K, the perforated spool,and the washers l-I j, said spool internally, and said cu p-leather being smaller in diameter than the main valve, said spool being arrangedin the upper part of the valvechamber, said passage D2 leading from said Outlet to the space surrounding said spool, said cup-leather working-within said spool, said washer H being interposed between the cap and the upper end of the body of the valve-chamber and said washer j being between said spool and the ledge b2 upon the valve-chamber, substantially as described.
4. The combination of the valve-chamber having the main valve-seat, the inlet, outlet, passage D2, and extension b2, with the valverod, the main valve, the perforated spool, the cup-leather K, and the cup-leather Mr upon the extension of the valve-stem, said spool being arranged above the upper limit of the stroke of the main valve, said passage D2 leading from said outlet to the space surrounding said spool, said cup-leather K working within said spool and said cup-leather M working within said extension b2, substantially as described.
Witness our hands this 26th day of June, 1891.
