Patented M arch 2,6,187'1 PATENT OEEICE.
PHILIP C. ROWE, OF BOSTON, MASSACHUSETTS.
IM PROVEIVlENT IN VALVE-COCKS.
Specification forming part of Letters Patent No. 125,086, dated March 26, 1872.
To all whom t may concern:
Be it known that I, PHILIP C. RowE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Valve-Cock or Faucet; and Ido hereby declare that the following, taken in connection with the drawing which accompanies and forms part -of this specification, is a description of my invention sumcient to enable those skilled in the art to practice it.
My invention relates particularly to the construction, organization, or arrangement of parts ofa self-closing water-cock, bib, or faucet, although the invention is also applicable to steamcocks. The invention consists, primarily, in the employment of a valve-spindle extending centrally oraxially through the vertical valvechamber, and having at its foot a valve, which bypressure of asprin g is carried upward against aivalvesat formed at the bottom of an auxiliary tube through which the spindle passes, this tube having` water-ways or ports through which the water, enterin g th rough the bottom of the tube when the valve is open, passes into the Veduction-tube, the valve being opened by simple depression of the valve-stem, and being closed by the springlwhen the spindle is rei lea-sed from dow'wardpressure. The cock is preferably made with a diaphragm-spring extending over the top of the main chamber and held in place at its edges and packed by the screwed-down cap, an auxiliary stem or lingerpiece extending through the cap, and by pressure acting upon a button at the center of the diaphragm, and thence upon the valve-spindle,
v this constituting one of the details of the invention. Above the water-ways or ports, nea-r the bottom of the valve-tube, is a flange or collar on the valve-spindle, which extends nearly but not quite to the inner surface of the tube, and a short distance above this collar is a rin g fixed on"the inner surface ofthe tube, through which ring the spindle passes, the ring lit-tin g closely to the spindle, but allowing the latter to slide freely through it. When the valve is open the upwardly-pressing water-passes by the lower collar into the space or chamber between it and the ring, and when the valve closesthis water acts as a cushion and prevents the valve from water-h ammering, as the valve cannot close except as the water flows tubes; c, the vertical tube or main chamber,
into and from which the induction and eduction tubes lead, and through which the valvestem d passes. e is the screw-cap. f is the valve-tube, and g the valve, said valvebeing preferably a leather disk or washer, secured at the end of the spindle by a screw-nut and washer, h. The valve is drawnup against the bottom of the tube (which forms the valve-seat) by the stress of a spring, t', and is also forced against said seat by the pressure of the water making a water-tight joint at the lower end of the tube. The valve-tube f projects down from a screw-cap,j, and at its bottom leads from the induction-chamber, and just above the valve-seat are ports or openings k leading from the tube into the eduction-chamber, the water (when the valve is open) flowing from the induction-chamber into the bottom of the valvetube, thence out from the tube through the ports into the eduction-chamber, from which it escapes through the eduction-tube. The spindle may also have one or more ports, g, made through it. The valve-spindle extends through the valve-tube and cap 7',- and its top is normally a short distance below the centerof the cap e, as shown in the drawing at A. Between the cap e and the spindle is a flexible and water-proof diaphragm, l, the edge of which is coniined between the cap and thetop or edge of the main faucet-tube o, the pressure of the cap upon the diaphragm packing the joint between the cap and the faucet, and thereby leaving a water-tight space between the diaphragm and the bottom ofthe cap. A stem 0r finger-piece, m, passes through the center of the cap, and when pressed down its lower end pushes down the center of the diaphragm (preferably provided with a metal button, 02,) against the valve-spindle, and the valve spindle being thus operated depresses and opens the valve and permits the water to flow through the faucet, the iiow continuing so long a-s the pressure is kept up upon the'stem. When the stem is released, the valve is thrown back by the stress of the spring and pressure of the water and closes the valve. It will thus be seen that the valve or faucet is self-closing, and as a water-cock is thereby made valuable as an aid in preventing undue Waste of Water, as the faucet cannot be left ruiming. The spring i may be dispensed with, andthe pressure of the water be alone depended upon to self-close the valve. I prefer, however, to use a spring having aslight stress, or just sufficientto close the. valve without the water pressure. the cap and be. packed in the cap, but I con- Sider the diaphragm and auxiliary stem as pret'- erable, as it insures great freedom of Inovement of the parts. For asteam-valve (and for a water-valve to be kept more or less open) the stem m ma vbel screw-threaded and work through a nut-thread in the cap, the valve be ing closed by turning the screw-stem hard up against the diaphragm and valve-spindle, and being opened to a greater or less extent by turning up the stem more orless. Just above the eductioi'i-ports of the valve-tube is the flange o on the valve-spindle, the ange not quite filling the tube, but leaving athin waterpassing space, p, between its edge and the surface of the tube. Further up in the tube is the ring 1' projecting inwardlyT from the surface of the tube to the valve-spiiulle, but leaving the spindle to movei'reely through it. When the valve is open the inrushing water passes by the ed ge ot' the ange o and lls the space between said ange and the ring r, and this be- The valve-spindle may extend through ing full of Water, the pressure of the Water (when the valve-spindle is released) can only close the valve as fast as the inclosed water can flow from the tube,'thus eectually preventing Water-hammering. Just above the bottom of the valve-tube said tube may be provided with au outwardly-proiecting flange, s, under which is aleather or other flexible washer, u, which, when the valve-tube is screwed down into place, is packed down upon Ialange, v, as seen in the drawing, and prevents leakage by the tube when the valve is closed.
I claim- The improved valve-cock, having, leading from the imlucton-chamber, the valve-tubef', with its surrounding space, the lower end of which tube forms the valve-seat. and leading from such tube into the eduetion-chamber, the water ports or passages r,'the valve-operating spindle d with its ilange o, formed with ay thin water-passage, p, at its edges, and the tubering` r, the stem d extending through the tube and terminating within the cap e, and the valve being opened by downward pressure upon the top of the spindle by the action of the separate stein m, and self-closing bythe pressure of the water or other tluid which may be aided by the stress of a spring, all as shown and described.
