seat opens into a bore'8 leading'to an inlet 9" on the back face of flang 4. Outwardfr'omthis seat the bore-of chamber 6 is tapped to provide a steep pitchsquarethread l'iwhic'h accepts the closing screw l0on valve stem l2. A packing nut I4 is then threaded into the-end of the-body to enclose the stem and compress: packing ring it. On the end of stem l2 a single wing handle l'lis splined and heldby ase't screwz A closing spring I8 surrounds shaft II with one end anchored to flange A and the-other'setinto" handle ll.

The inner portion of spout chamberli is drilled spout l9, and the outer; portion threadedto receive gland nut 20. A portion of the wall of chamber 6 is broken away to communicate with each of three port holes-'22, drilled through" the body part 3 parallel withits axisbuteccentrical lypositioned therefrom and opening into the: valve chamber 5. The combined crosssection'al' area of these three holes is less than that of either the inlet 9' or spout I 9, and togetherthey' form a constricted transfer passageway from the'valve chamber 5 to the spout: chamber 6-.

The spout has a threadedv axial portion 2.4" which retains it in position, and is their bent at: right anglesto provide a delivery'bib' extend; ing fromportion 25 at an angle; of 9orelative to the axialportion 2,6; This construction e'n-; ables the spout to be. swung out outward" for: delivery as, shown by the, solid lines in Fig: .2; or rotated to anout-oi-the-way position as indie} cated by'the. dotted: outlineiifi'. s s

Thevalve form shown in Figure 9 isof similar construction except thatxthe outerrtipr35xof spout [9. is, bent downward tov beparallel. to: the inner threadedportionqfl. v

' The advantages of" construction are obvious: By providing-a valve: bodywitha. cylindrical-body 3 tangentiallyjoined; to, an attaching: flangei'l';

the valve is very compact and is advantageous where space is to be conserved.

In use, the flange 4 is attached to a wall 21, which may be a sink back, or other vertical member, and the inlet tube 39 attached to a water supply pipe. The valve thread I, having a steep pitch, will open the valve on a quarter or half" turn. The handle is, therefore, positioned on the. stem so that it is vertical when the valve plug l3" is seated, as shown in Figure 3. When not .in; use, the spout I9 is kept in theraised position, .l5

as shown in Figure 2, or swung to one side as in dicated by numeral 38, Figure 9. When it-is to be used it is turned to the outward extended position-.- Outward motion ofthe handle l1 then opens the valve against the tension of spring I8.

A retum-motion closes it and this is accelerated by the urge of-this spring. v i

When the valve is opened water flows from the inlet into-the valve seat chamber, 5, as indicated by the arrows Figure 4. It then reverses its di-.

motion and flows through holes 22 at an increased velocity due to the constricted area of these holes, and thence at a slower velocity, into and through chamber 6 and, lastly, out through spout l9.

Now, when valve plug 28 is closed on seat I to 30 eil'ect ashut oil, water flowing through holes 22 at the greater velocity will continue to flowon through chamber 5 and out of spout IQ for an instant-due to its momentum of flow. This breaks the water columns flowing through these holes forming a partial vacuum in each. An instant after the vacuum has formed the out flow of water from the spout tip is stopped and the end portion of water in the spout drawn back into the spout by atmospheric pressure. The quicker the 40 closing action the greater is the vacuum action. Spring l8 assists in this. This action prevents any drip from the spout since the water is drawn back into it and away from its mouth. The size and shape of the'spout is such that the water in it does not tend to run out after the closing of the valve, and after it has been drawn away from the tip of the spout. Thus, since there is no water left at the tip of the spout to drip off, and since the remaining water does not tend to run out, due

cross sectional area slightly less than that of the opening through spout I9 and spout chamber 6. Together, these openings, downstream of the valve, from outlet passageways having a constricted area less than that of the inlet 9, bore 8,

and valve chamber'5, on the upstream side of the valve closure. Water entering from supply tube 39 under a constant head flows through the whole valve system at a constant rate of flow. Since passageways 22 are constricted-that is, have a smaller aggregate cross section than the passageways upstream of the valve-and since spout 19 has an interior passageway only slightly larger, the rate of flow downstream from the valve will be faster than that upstream thereof. The .flowl will attain, its greatest speed through passage! ways 22. The flow through these passageways, as well as through spout It, builds up kinetic energy according to the well known formula M V K where K=kinetic energy, M =mass and V=velocity. The result is that, despite surface friction and retarding due to change of direction, the velocity of flow is greater downstream of the valve than upstream of the valve and is greater than would be the case if the downstream passageways were the same size as the upstream passageways, or, were not constricted. The constriction-of passageways 22 (as well as spout [9) therefore, is responsible for the translation of kineticenergy from the potential energy of the head pressure, and for the increase of velocity in thezdownstreamxflow: Under these conditio s, when the valve is quickly closed the kinetic; en ergy in the downstream flow'carries the column ofj'water in passageways 22 and in spout 19 outward until itris dissipated by friction and the pressure of the atmosphere. This accounts for the formation of "a partial vacuum in the upper ends of passageways 22 for an instant after the valve is quickly closed., The kinetic energy and momentum of flow carry a portion of the water column on out of the end of the spout. The next instant, after this energy has been expended, atmospheric pressure forces the column of water remaining in these passageways back from the endof spout I9 and upinto them until thevacuum disappears.

Theoretically, disregarding friction, the smaller the downstream passageways, the greater the above described effect. Practically, constriction is limited as the point is reached where friction ofisets the gain in kinetic energy due to increased velocity. for the purposes here desired.

Another result of the constriction of passageways. 22 is that, since the velocity of flow through them is greater than it would be if they were not constricted, the water column travels further through them (along their length) during the first instant, above mentioned, after the valve is closed. Thus a greater length of water column is run out of the end of spout I9, and therefore there is a greater length of pull back into the spout the next instant, than there would be, if there was no constriction on the downstream side of thevalve.

While .I have described the preferred forms of my device,'it.'is obvious that many modifications can be made, but that the resultantdevice wouldstill remain within the spirit and intendments of my invention, and therefore, wish to be limited only by the following claims.

I claim:

1. In a water faucet having a cylindrical body, an attaching flange joined to the side thereof, an inlet entering through said flange, a valve chamber formed at one end of said valve body having? a valve seat and an inlet chamber connecting to said inlet, and a spout chamber at the opposite end of said valve body. the combination therewith of means to control dripping including a threaded valve' stem and a valve plug thereon adapted to. close on said valve seat, a closingspring on said valve stem adapted to aid closing motion of said stem to provide; quick closing .of 'said' plug'on said seat, a spout having an inside diameter sufliciently constricted toretain water therein by surface tension connected to said :spout'ehamber, .a, plurality of:

passageways having an aggregate cross sectional area constricted relative to said spout connecting said valve chamber with said spout chamber whereby water flowing therethrough attains suflicient velocity and kinetic energy to continue to flow momentarily out of said spout after said valve is quickly closed and water remaining in said spout will be forced inward from the outer end portion thereof by atmospheric pressure.

2. In a Water faucet having a cylindrical body, a mounting flange formed on one side thereof, a valve chamber at one end thereof having a valve seat at its bottom, an inlet opening below said valve seat, and a spout chamber formed within the opposite end of said body, the combination therewith of means for controlling dripping including a valve plug operative on said valve seat, means for causing a quick closing of said valve plug, a passageway extending longitudinally through said body connecting said valve chamber with said spout chamber, having a cross sectional area constricted relative to said inlet opening and valve chamber, and a spout connected to said spout chamber having an internal opening sufficiently small to retain water therein by surface tension, said passageway being restricted relative to said spout.

3. In a water faucet having a cylindrical body, a mounting flange formed on one side thereof, a valve chamber at one end thereof having a valve seat at its bottom, an inlet opening below said valve seat, and a spout chamber formed within the opposite end of said body, the combination therewith of means for controlling dripping including a valve plug operative on said valve seat, means for causing a quick closing of said valve plug, a passageway extending longitudinally through said body connecting said valve chamber with said spout chamber, having a cross sectional area constricted relative to said inlet opening and valve chamber, and a spout connected to said spout chamber having an internal opening sufiiciently small to retain water therein by surface tension but larger than the crosssectional area of said passageway; the constriction of said passageway being sufficient so that the velocity of flow downstream of said valve is increased to provide kinetic energy sufficient to force a portion of the water flowing through said passageway and spout out of the end of said spout after said valve plug is closed quickly on said seat, whereby a vacuum is momentarily formed in said passageway and immediately thereafter the water remaining in the outer portion of said spout is forced back into said spout and passageway to fill the space in which said vacuum was formed.
