anism for moving the valve, and designedtalso to rendervery simple the making of adjustments o'rfrepairs and to adapt the faucet to forms needful in modern plumbing.

Other advantages are referred to in detail hereinafter. The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a side elevation. is a central ver,

tical section. Figs. 3, 4, 5 and 6 are plans of rings used in packing. Eig. 7 is a section of the valve and connected parts. Fig. 8 is a central section illustrating a different style of packing. Fig. 9 is a central section illustrating another style of paeking.

Referring to the embodiment of the invention illustrated, the valve A is moved toward and from its seat B by means of a crank pin C connected thereto through a link D, the crank pin C being carried on a transverse shaft E, the outer end of which is shown at E/ in Fig. l, and which is rotated b`y means of an operating handle F on the outside. On turning the handle F to one position,the valve is lifted from its seat, and on turning the handle to the opposite position the valve is pressed against its seat, as in the operation of the ordinary Fuller faucet.

The faucet differs from the ordinary type, however, in having the valve close against the pressure. The Water, for example, moves in the direction of the arrow in Fig. 2, and the valve moves downward against it. By this arrangementa sudden closing of the valve at the end of its movement and a resulting severe concussion, such as occurs with valves closing with the pressure sometimes when they are new and always when they have become slightly Worn by use, is avoided. The rate of movement of the eccentric is a minimum at the instant of complete closing, and the water pressure resists the closing movement and tends to prevent the concussion referred to. If thereis a slight lost motion in the mechanism for moving the valve, the sudden increase of water pressure at the closing instant tends to take up this lost motion and to relieve the suddenness of closing; whereas when the valve closes with the pressure the sudden pressure arising at the instant of closing hastens the movement of the yalve and causes a more or less severe concussion. The val ve is also held rigidly in all its positions by the eccentric mechanism, and bya suitable guide, so that in the open position'there can be no drumming or rattling of the valve. For this purpose the valve is guided to and from its seat by a special guide provided for the purpose, and is packed in said guide. Such a rigid movement has been avoided heretofore, the

valve being loose so as toenable it to ad'just itself per-4 fectly to its seat. I provide'a valve, however, which is hollow and expansible, havingy an opening toward the water, whereby the latter may epter and expand it, thus providing relief for the pressure'atthe instant of closing,

and at the same 'time pressing the valve accurately 'against all parts of its seat so as to insure a tight closure.

The hollow space within the valve provides also an air chamber into which the water may flow against an elasl .tic back pressure of air, which further serves to diminish concussion; and this feature of making the valve hollow may be used in unyielding valves for this purpose.

A specific construction is shown in section in Fig. 7. The valve A is of'rubber or other yielding composition, with a vconical outer face fitting a correspondingly shaped seat, and a hollow space G in the centeropening downward toward the water pressure. This valve is fastened, as by a screw H, inthe lower end of a plunger J, which moves in a cylindrical guide K. A ring of packing material L is provided ina circumferential groovevof the plunger J, which holds the plungerrigidly in all positions and prevents rattling or drumming. At thesame time the packing L preferably extends beyond the periphery of the metal plunger J so as to prevent any contact between the metal plunger and its metal guide. The packing is also preferably made substantially water-tight, so'that there is no access of water or grit to the operating mechanism above the plunger J, and these parts are accordingly saved considerable wear by being cut off from the chamber M through which the water flows.

The elimination of drumming and concussion relieves the entire plumbing system of a building of its greatest strain, and the improvements provided in these respects are of the greatest value.

,An important feature of the invention is the arrangement bywhich the valve and its operating means are' together adjustable toward the seat to takeup Wear. In the old style faucet, when the valve or mechanism wears, and it is desired to readjust the valve, it is necessary to turn off the water, usually in the cellar of the building or outside, break a joint in the, part of the faucet ordinarily subjected toavater pressure, and adjust the ball or valve on its stern. This adjustment is effected by guess, after which the parts are replaced and the water again turned on. If the faucet still leaks the process has to be repeated. -By adjusting the valve and operating4 mechanism togetheraccording to this invention, there is no need of breaking any joint in the pressure part of the faucet. Preferably there are ytwo parts'ofthe casing, one carrying the valve seat.

and the other carrying the valve, said parts oeing bodily adjustable toward each other.

In the example shown, the tube K is extended upward and is integral with the upper chamber N carryl ing the eccentric-operating mechanism and from which the shaft E E projects laterally, and this upper portion of the casing, which Idesignate as a whole by the letter O, is adjustable in the lower part P which carries the valve seat. Preferably the upper member O has a screw-threaded connection, as Q, with' the. lower part. For example, screw-threadsof l/32 of an inch pitch may be used, so that one complete rotation of the upper member O relatively to the lower member P will bring the valve 1/32 of an inch toward or away from its seat; thus providing for a very fine adjustment while maintaining the operating member at the same side of the spout R. This same construction serves to permit an angular adjustment of the operating handle relatively to the spout, so that the handle may be located at the right or left or in front or back as desired. With previous faucets of the Fuller type it has been necessary to construct two patterns, one right-hand and the other left-hand. My improved faucet is universal in this respect. By merely swiveling the part carrying the `handle relatively to the part carrying the spout, this particular advantage may be obtained without the necessity for screw-threading one part relatively to the other, and such a construction is within my invention. i

It is preferable to provide special means for clamping the two parts together in the desired position of ad.- justment. For this purpose I may provide an outside nut which serves at the same time topack the joint between the parts O and kP of the casing. For example, the nut S maybe provided, rotating freely on the vertical neck of the upper member O of the casing, and screwing down upon the neck of the lower member P; and having within it clamping and preferably also packing rings. Such rings are Ashownin detail in Figs. 3, 4, 5 and 6. The ring Tl may be of brass or other hard metal split at one or more points and having a conical outer f ace engaged by a conical inner face of the nut S, so that as the latter is screwed down the ring T is squeezed together about the neck ofthe member O and clamps it firmly. The rings U and V are of lead or other soft packing material, split at one or more points, and tapered on their outer faces so as to be squeezed together to make a good water-tight joint. Between the soft ring U and the hardsplit ring T there is preferably interposed a continuous ring W of brass or other hard metal which serves to prevent the forcing of lead up into the split of the ring T and so interfering with its clamping movement. The upper edge of the neck of the casing member P, and the lower face of the complete ring W are hollowed out to fit the conical faces of the lead rings U and V.

Although the packing arrangement just described has evident advantages in this particular faucet, yet it is possible tol employ therewith various other types of packing, such, for example, as that shown in Fig. 8, in which the nut S forces a gland X down against rings Y of any suitable packing material.

The faucet is adapted to be applied ,to a slab or similar support Z.. TheVA base of the casing rests directly on the slab, and the member a carrying the valve seat B passes up through the slab and through the base of the casing. The valve seat member is provided with a squared portion b for screwing it in place. The faucet is held in place by means of a nut c screwing upon the outside of the seat member.

The construction isspecially adapted to the low down form shown, and also to the numerous known forms of double or mixing faucets. For example instead of the lavatory arrangements shown, the faucet may be'very conveniently arranged for the usual or any suitable piping for kitchen sinks, laundry tubs,

bath4 tubs, and other apparatus. Because of 'the possibility of the universal adjustment, the parts may be arranged so as to present the minimum projection into the fixture.

Instead of the double packing shown in Figs. 2 to 6, the outer packing may consist merely of a single complete lead ring d having conical upper and lower faces engaged by corresponding faces on the inside of the nut S and the upper edge of the portion P of the casing'. I have found by tests that this simple construction packs the casing and holds it rigidly in position.

Though I have described with great particularity certain specific embodiments of the invention, yet it is not to be understood therefrom that the invention is limited to the specific embodiments disclosed. )Various modifications thereof in detail and in the 'arrangement and combination of the parts may be made'by those skilled in the art without departure from the invention.
