SPECIFICATION forming part of Letters Patent No. 639,484, dated December 19, 1899. Application filed March l0, 1899. Serial No. 708,487. (No model.)

To all whom t may concern:

Be it known that I, JOHN B. WoonwoRTH, a citizen of the United States, and a resident of Manlius, in the county of Onondaga, in the State of New Yrk, have invented new and useful Improvements in Faucets, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of faucets in which the valve is disposed with its back toward the liquid-inlet of the faucet, and thus forced onto its seat by the pressure of the liquid.

Theinvention consists, first, in an improved connection of the valve to the valve-stem which permits the valve to be readily detached from the stem when desired to repair or renew the valve and also allows the valve to rock on the stem sufficiently to conform to the plane of the valve-seat and which also effectually prevents the liquid from escaping through the bore through which the valve-stem passes; and the invention also consists in othernovel features of construction, as hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure lis a side View of a faucet embodying my invention. Fig. 2 is a longitudinal section of the same. Figs. 3, 4, and 5 are transverse sections on lines X X, Y Y, and ,e z in Fig. 2, viewed in the directions of the arrows. Fig. 6 is a transverse section on line z .c with the valvestem removed. Fig. 7 is an enlarged sectional View taken on line V V in Fig. 4, and Fig. 8 is a detached perspective View of the inner end portion of the valve-stem.

Similar letters of reference indicate corresponding parts.

A represents the body of the faucet, and B the head of the faucet. Said body is formed with an annular cavity O, the free or front end portion of which is screw-threaded and has secured in it the correspondingly-screwthreaded rear end portion of the head B, as shown in Fig. 2 of the drawings. The opposite or rear end portion of the body A is formed with a screw-threaded nipple A for attaching the faucet to the barrelor other receptacle containing the liquid to be drawn therefrom.

Said nipple is hollow to form the l liquid-inlet C to the cavity O. The inner face of the head B is formed with anannular fiat valve-seat d, provided with the eductionport b, which communicates with the disfitted tightly to the seat a and presenting its 6o back toward the liquid-inlet O', so as to be forced onto the seat d by the pressure of the liquid from said inlet, and thus rendered selfseating. Said valve is provided with a port d', which by the turning of the valve upon its 65 seat is carried into and out of communication with the port b.

In order'to prevent sediments or impurities of the liquid or other substances from gathering on the valve-seat in front of the port d 7o and tending to clog the valve, l taper the port d' toward the valve-seat, so as to forni around the end of said port an acute-angled edge which scrapes the path of the port along the valve-seat during the operation of turning the valve. At the saine time the Hare of the port from the valve-seat augmente the clearance of said port to facilitate the escape of the scrapings from the port.

I preferably provide the valve with two 8o ports d CZ', diametrically opposite each other, so that the valve can be opened by turningit in either'direction from its closed position.

c represents the valve-stem, which passes through a cylindrical bore f, through the head B at right angles from the plane of the valve-seat ce, said bore terminating in a circumferential enlargement f at its outer end for the `purpose hereinafter eX- plained. cured to the valve to permit ready repairs or renewal of the valve when required. Said connection consists of an orifice gin the cen ter of the valve and radial slots g' g', extending from said orifice.

provided with notches h h, which are disposed between the slots g g', as shown more clearly in Figs. 5 and G of the drawings. The inner end of the valve-stem e passes through the orifice g and is provided with roo radially-projecting lugs ZZ, shaped to pass through the slots g g', and by turning the extending 8 5 Said valve-stem is detachably se- 9o The back of the valve is a eea-isa valve-stenrsaid lugs are broughtI into positions to enter into and become interloclied with the notches h 71,. To permit the valve to rock more freely on the valve-stem, and thus accommodate itself more readily to the valve-seat, I form the interlocking portions of the lugs convex or rounding, as shown at Z in Fig. 7 of the drawings.

To retain the valve-stem interlocked, as aforesaid, I place in the enlargement f/ of the bore f a spiral spring t, which presses with its outer end ou the handle D, which is suitably secured to the protruding end of the valve-stem and may be of any desired and suitable shape. Said pressure of the spiral spring forces the valve-stem outward and causes the lugs Z Z to be retained in the notches 7i 7L.

To effectually guard against escape of liquid through` the bore f, I form the back of the valve d with a cap t', which completely houses the orifice g and slots g g, as shown in Figs. 2 and 7 of the drawings. Said cap is formed with a cavity t" to allow the valvestem to pass through the valve d sufficiently to permit the valve-stem to be connected to and disconnected from the valve when desired, as hereinbefore stated.

What I claim as my invention is- 1. The combination with the faucet-head provided with the annular flat valve-seat and the cylindrical bore extending through said head and seat, of the valve provided in its center with an orifice, the valve-stem detachably secured in said orifice, a cap on the back of the valve and completely housing the aforesaid orilice and a spring forcing said stem outward and thereby retaining the same in its attachment to the valve as set forth.

2. The combination with the faucet-head provided with the annular flat valve-seat and with the cylindrical bore extending through said headand seat, of the valve provided in its center with an oriiice, radial slots extending from said oriiice and notches in the back of the valve and disposed between the aforesaid slots, and a cap on the back of the valve and completely housing the aforesaid orifice and slots, the valve-stem extending through the aforesaid bore and through the orifice in the valve and provided with radially-projecting lugs shaped to pass through the radial slots and interlock with the notches in the valve, and a spring forcing the stem outward and retaining the lugs thereof interlocked with the notches as set forth.

The combination of the faucet-head provided with an annular iiat valve-seat and with the cylindrical bore extending through said head and terminating with a circumferential enlargement at its outer end, the valve provided with a central orifice, radial slots extending from said orifice and notches on the back of the valve, the valve-stem extending through the aforesaid bore and through the orifice in the valve and provided with radially-projecting lugs Shaped to pass through the aforesaid slots and interlock with the notches and having the interlocking portions rounded, a handle attached to the outer end of the valve-stem, and a spiral spring seated in the enlargement of the aforesaid bore and pressing on the handle to force the valve-stem outward and thereby retain the same interlocked with the notches of the valve as set forth.
