installed and manipulated, and which will give long-life satisfactory service without impairment of any of its working parts,

Particular objects of the invention are to pro- 15 vide an improved faucet structure which can be operated to discharge water of all desired temperatures from cold to hot by the manipulation of a'single control element; also,'to provide a structure which makes such control very flexible 20 so that gradations of water temperature merge quickly one into the other and are easily ob- 'tained.

The annexed drawings and the following de scription set forth in detail certain means illustrating the improved faucet, such means constituting, however, only one of the various forms in which the principle of the invention may be embodied,

Referring to the annexed'drawings, in which providing for ure 2; i. e., when cold water is being fed to the 3 into a central cylindrical chambered portion 4 having a port 5 communicating with the conduit 2 and a port 6 communicating with the conduit 3. The central chambered portion 4 is formed with an upper-end internally-threaded collar 1 adapted to engage with the externally-threaded projection 6' of a cap 8. The cap 8 is formed; with an upwardly extending nut-like boss 8 which is tapped so as to engage with an ext'ernally threaded post-like pedestal 9 depending from a soap dish l0, Figure 1. 'Thus the soap dish ill, which may be formed of a phenolic condensation product, is supported by the cap 8 and above the latter.

The hot and cold water which pass into'the central chambered portion 4 are eventually discharged for use through a manually manipulative control spout I, Figure 1. This spout II is formed with an inner upwardly-extended portion 9 I journalled in a nut I5 and having an enlarged upper cylindrical portion [2 journalled on the inner surface of the central chambered portion 4. The bottom edge of the enlarged portion l2 forms a shoulder is which rests upon a collar N5 of the nut l5, the nut 15 engaging a downwardly extending threaded boss I! of the chambered member 4. Thus, the spout I is supported by the chambered member 4, but is pivotally mounted relatively thereto, the spout members l and I2 sliding on the cylindrical inner surfaces of the nut l5 and the chambered member 5, respectively. Fibre washers l4 and I8 are placed, respectively, between the shoulder l3 and the nut collar l6, and between the flange I! of the member 4 and the top of the body of the nut l5, adjacent the thread-engaging portions of the member 4 and the nut |5.-There is also a gasket 43 between the'collar l .and the cap 8. The outer face of the spout portion ll which is journalled in the nut i5 is formedwith a circumferential recess H which accommodates a cup washer Is. It is thus evident that leakage between the chambered member 4 and the spout portion 12, between the chambered member 4 and nut 5, between the nut l5 and the spout portion H, and between the chambered member 4 and cap 3, is effectually prevented.

Ihe upper enlarged spout portion I2 is formed with ports 26, 2|, 22, and 23, of which . ports 20 and 2| are adaptedin certain positions of. the spout H to be aligned with the hot water port 5 of the central cylindrical chambered portion 4, and of which ports 22 and 23 are designed in certain positions of the spout II to be aligned with the cold water port 6 of the central cylindrical portion 4. Within the upper enlarged spout portion i2 is supported a chambered plunger.25 hav: ing an open top and a closed bottom, this plunger 25 being provided with a washer 26 depending from its closed bottom portion and secured thereto by a screw 28, this washer 26 forming a valve and being adapted to a seat portion 21 formed at the top of the nozzle portion H and around a top opening therein. The plunger 25 is adapted to be moved vertically in the enlarged spout portion l2, the plunger 25 having a plurality of spaced tongues 46) formed exteriorly of its main body which slide upon the inner wall of the spout portion l2. Thus, when the parts are assembled, there is provided between the tongues 46, and between the inner face of the .spout portion l2 and the opposed outer face of the plunger 25 a series of circumferentially-spaced narrow chambers 4|. The bottoms of these chambers 4| open into a continuous chamber 42 around the bottom of the plunger 25 and thus have communication with the interior of the spout when the valve 26 is lifted from the seat 21, as clearly appears in Figures 7 and 8.

Means are provided insuring the lifting of the valve 26 from the seat 27 when it is desired that water should be discharged from the spout II,

and these means consist in a spider portion 32 in the form of a flange at the top of the plunger 25, which spider 32 has a pair of diametricallyopposed arms '33 in which are mounted upon pins 3| rollers 29 which, in a closed position of the spout depend into arcuate recesses 24 formed in the top of the enlarged spout portion l2. The spider 32 also has a pair of diametrically-opposed slotted arms 34 between the respective parts of which slotted arms extend a pair of vertical pins 35 which are formed with shoulders 35 and are supported by the central cylindrical chambered portion 4, the arms 34 and pins 35 thus forming guides for the vertical movements of the plunger 25. Ordinarily, the plunger 25 is held in its lower position, with the valve 26 closely engaging the seat 21, by a coiled spring 35 which bears at one end against the closed bottom end of the plunger 25 and at its other end against the under surface of the cap 8, being centralized by a post-like member 8 which depends from the cap 8 into the plunger 25. In the lowermost position of the plunger 25, the valve 26 rests upon the seat 21, with the rollers 29 disposed somewhat above the bottom of the arcuate recesses 24, Figure 4, but closely adjacent the side walls of said recesses. When the spout H is turned to various positions, as indicated in Figure 2, the rollers 29 contact with the walls of the recesses 24 and ride upwardly on said walls and out of the recesses 24, which lifts the spider 32 and hence the plunger 25, thus lifting the valve 26 from the seat 21. However, there is substantially no rubbing of the valve 26 on the seat 21 since the turning of the spout l| immediately causes the rollers 29 to commence to ride up on the walls of the recesses 24, thus lifting the valve 26 immediately off the seat 27. If the valve 26 becomes somewhat worn, it is still held closely in engagement with the seat 2! by the spring 30' 24 but are disposed somewhat above said recesses 24, as hereinbefore explained.

As before mentioned, control of the water flow through my improved faucet, and the desired temperature of the discharged water, are eifected entirely by manipulation of the spout I. For conveniently manipulating the spout II I provide thereon adjacent its outer end a hand piece 39 formed of a phenolic condensation product or other poorly heat-conductive material. Figures 9 and 13 show the relative position of the various control ports when the faucet is entirely shut off. Under such conditions, the spout H is either at its extreme left-hand position, Figure 9, or its extreme right-hand position, Figure 13. Stop lugs 38, Figures 1 and 3, are provided beneath the end faucet members I, which prevent the swinging of the spout H to the rear of the conduits 2 and 3, so that it is only necessary to throw the spout II to its extreme right-hand or left-hand position, determined by the stop lugs 38, in order to shut the water oil. In the accompanying drawings it is assumed that predominantly hot Water will be discharged when the spout II is to the left of its intermediate position, and that predominantly cold water will be discharged when the spout is to the right of its intermediate position (see Figure 2). It is assumedthat substantially entirely hot water will be discharged when the spout is in the left-hand position marked "hot, Figure 2, the port relations for this condition being shown in'Figure 10; and that substantially entirely cold water will be discharged'when the spout is in the position marked cold, Figure 2, the relative port positions therefor being shown in Figure 12. When the spout II is in the central position marked mixed, Figure 2, it is assumed-that hot and cold water both are being discharged in substantially equal amounts. The relation ofthe ports for this condition is shown in Figure 11.

Assuming that the several elements are in the relative positions shown in Figure 4, with the spout H in its extreme left-hand position contacting one of the stop lugs 38, Figures 1 and 2, it will be noted by further referring to Figure 9 that the port 5 from the hot water conduit 2, and the port 5 from the cold water conduit 3,are closed by the wall of the upper-enlarged cylindrical portion l2 of the spout Pulling the spout II forwardly will turn the spout portion l2 and the port 26 thereof will approach the hot water port 5 and register therewith in the position of the spout marked hot, Figure 2, this port registry being shown in Figure 10. Hot water will'then pass through the ports 5 and 20 into one of the chambers 4|. This movement of the enlarged spout member l2 causes the pair of opposed arcuate recesses 24 formed in the top edge of the 1 member l2 to move'under and their walls to push upwardly upon the rollers 29, thus lifting said rollers and hence 'theplunger 25 within which they are mounted, and efiecting a lifting of the valve 26 secured to the bottom of the plunger 25 from its seat 21, whereby the water is discharged into and through the chamber 42 and thence through the spout portion ll into the spout l whence it is discharged. The continued movement of the spout II from the position shown in Figure 10 further toward the right gradually shuts off communication between the ports 5 and 26, not, however, freezing cylinder 25 from its upper position, so that drainage of drip water between the valve 26 and theseat 21 continues. As the spout I moves further to the right the port 2| in themember |2 comes into registry with the hot water'port 5 and the port'23 comes into registry with-the cold water port 6, so that both hot and cold water are discharged from the spout l I. This condition is illustrated in Figure 11 and it will be evident that according to the respective amounts of registry between the ports 5 and 2| and the ports 6 and 23, respectively, the desired amounts of hot and cold water, so as to obtain the desired temperature of mixed water, can be controlled. Continued movement to the right of the spout ll eifects eventually the registry of the port 22 with the cold water port 6, the various ports being so arranged that at this time there is no passage-of hot water possible through the port 5, so that entirely cold water is discharged from the spout Further movement of the spout II to the right shuts off all water and the spout movement, with all water shut off, is finally. stopped by the right-hand lug 38. This condition is illustrated in Figure 13.

In Figures 14 and 15, I illustrate an improved adjustable spout structure which provides for discharge of water therefrom in difierent directions. Thus, the water can be discharged down- 7 wardly into the sink or other receiving receptacle at different angles, or can be discharged at any desired higher angle for spraying or rinsing of utensils held above the sink or for other desired purposes. This improved spout structure comprises the tubular elements 46 and 41, the inner surface of a reduced end part 41 of the element 41 closely engaging the outer surface of a reduced end part 46' of the element 46, so that the element 41 turns on the part 46', whereby water can be discharged in any desired direction through a discharge nozzle 48 formed on the adjustable element 41. The end of the main body portion of the element 46 forms a shoulder 49 against which the inner end of the part 41 abuts, in the assembled condition of the structure. The inner surface of the part 41' and the outer face of the part 46' are cut away so as to form a chamber 50 therebetween, the cut-away portion of the part 41 being somewhat longitudinally elongated so as to provide an outer end chambered part 55. The end walls of the cut-away portion of the part 46' taper inwardly, as indicated by 53. Furthermore, the inner end wall of the cut-away portion of the part 41 forms a shoulder 54. The elements 46 and 41 are locked in assembled condition by a coiled spring 5| which, in the assembled condition of the elements, abuts the top Wall of the cut-away portion of the part 41' and at form a continuous uniform conduit through the spout.

The aforedescribed elements and the structure and relative arrangement of the same are important from the standpoints of the easy assembling and disassembling of the spout elements 46 and 41 and the retaining of the same in locked condition without the necessityvof other locking elements. Assuming that it is desired to take the elements 46 and 41 apart, it is necessary only to pull axially in opposite directions upon the elements 46 and 41 which will cause the shoulder 54 to compress the right-hand end of the spring 5|, thus permitting'the shoulder 54 to ride up over this end of the spring, accommodation being provided for the reduction in the diameter of the spring 5| by the inner part of the chamber Continued pulling upon the members 46 and 41 will cause the shoulder 54 successively to depress and ride over the coils of the spring 5|, so that the members 46 and 41 are thus slidingly pulled apart. When it is desired to assemble the elements 46 and 41, the part 41 is pushed over the outer surface of the part 46', after the spring 55 has been placed in the chamber 50, sothat a beveled inner corner 52 of the right-hand end of the part 41' encounters the left-hand end of the spring 5| and depresses the same downwardly into the chamber 50, thus enabling the right-hand end of the part 41' to ride over the left-hand end of the spring 5| after which the coils are successively depressed by the beveled inner corner 52 and successively passed by the right-hand end of the part 41', so that finally the part 41 is pushed tightly up against the shoulder 49 and the spring is released from the right-hand tapered edge 53 and assumes its normal locking position against the shoulder 54 and the left-hand tapered edge 53, and the top wall of the cut-away portion of the part 41. The slight longitudinal enlargement 55 of the cut-away portion of the part 41' provides a margin of safety whereby it can be definitely assured that the outer end wall of the part 41' reaches and abuts the shoulder 49 of the element 36 before the wall 55' of the cut-away portion of the part 47 encounters the left-hand end of the spring 55. There is also provided a slight clearance area 56 between the body portion of the element A? and the end wall of the part 46'.
