Application filed December 6, 1926. Serial No. 152,929.

This invention relates to sink faucets, and

has pnrticuler reference to a. novel construction and errengement or the spout by which the water is discharged into a sink, or the like.

The obiect oi the invention is to provide sink rennet or" the single valve type that supplies and mixes the water at various temby menus of a. single control, the discharge from the mixing her the valve is eil'ected by a swingc-out, which distributes the water to "e: a ports of the trey of the sink. The primary object oi the invention is to provide novel, simple end effective means for presputtering or splashing oi the wawh n it strikes the bottom oi the sink, moons consisting oi a. normally member, which is disposed r pussege between the mixing id the spout. and nominally pe chc functions of e. bushing: the said receiving the mixture through its volutions and discharging" the we.- v into the spout; one end of the disposed adjacent the huinher directly in the grrnvitative the "WEttE-l and adapted to contract r the volume of the water dispensed equalizing; the volume disn scour, the normal tension spring being such that when the "s opened to e certnin extent the en- ?cug h the said member without con uy elf its coils and without causspetterinr-y after it leaves the spout, en the vnlve is opened to at greater nccordinggly discharges a. larger t pressure, the normal tenmember is overcome and the contrncte and correspondingly resuhstentinllv to the normal volume ised by the initial or partial opening -u valve.

v o erious ntures and parts of the invention will be understood by the detailed descripnon which follows. and by reference is accompanying drawing, in whichl is u. broken front elevation of e. to which my improvement is applied. is 51 side elevation of the same. Fig.

Fig. 4 is an enlarged broken elevational view of the swing spout. F. 5 is a. top plan view of the same. Fig. 6 is a fragmentary View of the neck of the spout, showing the contraction of the tension member for reducing the volume of water discharged through the spout at the highest pressure. Fig. 7 is an enlarged elevational view of the tension mem her. And Fig. 8 is a detached view of the plug, which closes the top end of the spring.

In the drawing, 2 represents an ordinary sink including the usual tray 2'. 3 repre- .is shown, for example. in position for drawinn hot water from the arm 5', and from which the water is discharged into 9. mixingchamber 4, via. aligning ducts or ports v5=-4. The valve is also provided with a cold water port 4 (see Fig. 3) which is arranged to align with a similar port 5" of the body 3. The valve 4 is tapered and seats in the correspondingly shaped chamber 3' of the body. Below the valve 4, the casing .3 is formed with a hollow externally threaded discharge neck 3", to which a swing-spout 6 is pivoted. The spout 6 is formed at one end with a globular portion 6', which has an upwardly facing opening 6", in which a. bushing 7 is preferably permanently fitted, as by brazing or the like. The free orouter end of the bushing 7 is formed with an annular flange 7, which is arran ed to seat against a downwardly facing s oulder or ledge 3 of the neck 3. The bushing 7 above the flange 7 preferably closely'but movably 9 fits the bore of the neck. The spout 6 is detachably and swingably connected to the neck 3 by means of a gland nut 8 (see Figs.

1, 2 and 3). Within the nut 8 is disposed a-.packing 8, which is engaged by the end of the neck 3 and prevents leakage of the joint. The nut 8 is allowed a limited axial movement by a sleeve or collar 8, which is loosely mounted on the bushing 7 below the v flange 7". The diameter of the said sleeve preferably equals that of the said flan e, and to ether with the flange efiects a re atively Iong smooth bearing contact with a counterborefi of the neck. This enables the spout to be swung in diiferent directions without exerting any undue strain or wear on the parts of the joint. The water flowing into the mixing chamber 4 gravitates towards the neck 3 and the bushing 7, and ordinarily passes freely into the spout 6 to be discharged into the tray 2', or other receptacle. In cities, the water is supplied at relatively high p1'essure-usually from to pounds per square inch--and discharges into a sink with a force that is relative to the said pressure, and except when the valve 4 is but slightly open, the water strikes the bottom of the sink with suflicient force to spatter over a considerable area, even beyond the borders of the sink. This spattering, which invariably increases with the further opening of the valve, is largely due to the increased volume of the water that is discharged through the enlarged opening of the valve, and by the time the valve is opened to its fullest extent,

the spattering becomes a veritable spray. In order to obviate this spattering or splashing of the water, I provide a novel and.

simple flow or volume reducing medium, which comprises a normally open-coil spring member, as 9, which is dlsposedpartially 1n the -neck 3 and partially in the globular portion 6' of the spout, as best seen in Figs. 3, 4, 5 and 6. The spring 9 virtually performs the function of a bushing, and conducts the water received from the mixing chamber 3, and the void 3 immediately below the valve 4, directly into the globular part 6. The top end of member 9 is preferably closed by the flanged head or top 10,

of a solid bushing or plug 10, which is rigidly fitted into the said member. The head 10 presents a relatively broad flat surface against which the water strikes immediately after it leaves the chamber 4*. Below the flange 10' the plug is formed with a cylindrical portion 10, which preferably tightly fits into the bore of the memher 9. The tension of member 9 is preferably such that when the valve 4 is only slightly opened and discharges a relatively small volume of water by pressure too low to compress or contact the said member, the water flows freely through the openings 9- between the convolutions of the member, and reaches the spout 6 without any perceptible reduction in the volume. This free flow of the water is facilitated by a reduced lower portion 10 of the plug, which is consiclerably smaller than the bore of the mem her 9. -When however, the valve 4 is opened to a greater extent, a larger volume of water passes through the valve at correspondingly higher pressure. hen this larger volume of the water encounters the member 9, it tends to correspondingly compress and close up the convolutions of the spring 9, thereb restricting the flow of the water throng the spout to substantially the same volume, as when the valve is only partially opened, as explained. The capacity of the ports of the valve, the mixing chamber 4*, and the bore of the reducing member 9 as well as the tension of said member, all are preferably computed and arranged so as to effect the same flow, by volume, of the water, no matter in what position the valve 4 may be set, and this predetermined volume is preferably so regulated that the water strikes the bottom of the sink without any perceptible spattering or splashing. When the member 9 and related parts are properly constructed and arranged, a copious flow of water is insured, and all noise and spattering, as well as waste of the water, are obviated. Obviously, the convolutions on, s ring 9 may be normally separated tiiroughout its length, as shown in Fi 3, or a portion of the coils may be substantially closed, as shown in Fig. 7 without departing from my invention.
