7 3 Claims. 1 a My invention relates to improvements in spigots.

A primary object of my invention is to provide a spigot for sinks, washstands and the like, and including a swiveled spout or nozzle which may be directed upwardly to form a drinking fountain, or downwardly for conventional usage.

A further object is to provide a spigot of the above-mentioned character having novel means to prevent the spigot from being turned on, ex-

Accordingly, it is another object of the inven tion to provide a spigot including a swiveled spout which may be turned only when the spigot is completely turned off or closed.

A further object is to provide a spigot of the above-mentioned character which is highly simplified and compact in construction, extremely strong and durable, and very easy to manipulate.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a central, vertical, longitudinal, sectional view through a spigot embodying my invention, parts broken away;

Figure 2 is an enlarged, fragmentary, central, vertical section through the spigot, and showing parts thereof arranged in different operative positions from their positions of Figurefl, part in elevation;

Figure 3 is an enlarged transverse vertical section taken on line 3-3 of Figure 1;

4-4 of Figure 1; I

Figure 5 is an enlarged perspective view of a sleeve removed, part in section; and

Figure 6 is an enlarged, fragmentary, side elevational view of a valve stem removed.

In the drawings, where, for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral l0 designates a stand pipe of a spigot which includes an upright valve body or casing ll screw-threaded at its upper end, as shown at [2, for the reception of the usual packing nut, not shown. The bottom of the valve body H is provided with a flat, radial flange l3 adapted to be seated upon the top of a wash basin or the like. The, upper end of the valve body H is provided with an internally screw-threaded bore I4 for receiving herein th usual screw-threaded valve stem or actuator 15 including a top reduced extension or shaft IE to which the usual handle, not shown, is secured. The screw-threaded bore I4 leads into a central, enlarged, internal recess l1 forming a chamber, and the bottom side of the recess I7 is provided with a shallow counterbore I8 which leads into a reduced bore or passage IS, in turn leading to the bore of the stand pipe I0. The bottom of the counterbore I8 is provided with an annular valve seat 20 surrounding the reduced bore l9, and the usual flat washer 2! is secured by means of a screw 22 or the like to the bottom end of the screw-threaded valve stem 1 5. When the stem [5 is turned for completely shutting off or closing the spigot, the washer 2| will be seated upon the annular valve seat 20. The construction thus far described is conventional and well known.

The valve body or casing H further comprises an integral, laterally extending projection or boss 23 having a flat, outer end. face 24. The boss 23 is provided in its outer end 24 with a large, screw-threaded recess 25 leading into the recess or chamber I! and having a flat, inner end or bottom 26 parallel with the outer end 24 and with the axis of the valve stem I5.

An annular, screw-threaded ring or sleeve 21 is mounted within the screw-threaded recess 25, and seated upon a suitable lock washer 28 which engages the inner end or bottom 26 of the recess. The ring or sleeve 21 is provided at its outer end with a radially inwardly projecting, annular flange or extension 29 flush in assembly with the outer end 24.

A swiveled spout or nozzle 30 is provided, and this spout 30 is elongated and preferably conically tapered, as shown, and formed at its free or outer end to provide a short, transverse or lateral discharge extension 3| having its axis disposed at right angles to the passage or bore 32 of the spout. The spout or nozzle 30 has a fiat, inner end or face 33 for sliding engagementagainst the outer end 24. The diameter of the end 23 is preferably the same as the diameter of the outer end 24 of boss 23, as shown. The spout 30 is provided in its inner end 33 with a central, axial, screw-threaded recess 34 receiving therein an elongated bearing sleeve 35, the bearing sleeve being externally screw-threaded at its outer end, as shown at 36, for engagement within the recess 34. The outer end of the bearing sleeve 35 is seated against a lock washer 31 which is mounted within the bottom of the screw-threaded recess 34. The bore 38 of the bearing sleeve 35 communicates directly with the bore or passage 32 and chamber or recess ll, as shown. The hearing sleeve 35 is thus adapted to rotate with the nozzle or spout 35, and the bearing sleeve extends through the bore of the ring or sleeve 2? and 18 provided at its innermost end with an integral, radially projecting, annular flange 39. The outside diameter of the annular flange 39 is slightly smaller than the inside diameter of the lock washer 28, as shown. The outer side or face 51) of the flange 35 is inclined or beveled, as is the inner side or face 4| of the annular flange 28, so that a continuous annular passage or space is provided between the periphery of the bearing sleeve 35 and bore of the ring 21, and this annular passage extends between the beveldfa'ces 40 and 4|, as shown.

Suitable thin, metal washers 42 are seated against the faces 45 and 4|, and disposed within the annular passage between the bearing sleeve 35 and ring 21.. A tubular, lubricating'seal or washer 43 is provided, and mounted within the passage between the :bearing'sleve '35 and ring 2?. The opposite ends ofjthe lubricating seal 43 are beveled, as shown, for en gement withthe metallic washers 4}. The element 43 is preferably formed of semi-hard" rubber or synthetic rubber preferably impregnated with fine graphite or some other suitableis ol id lubricant." The arrangement is such that mana er's held firmly against rotation-within the boss 23, while the spout 3t! and bearingsleeve'35 are held against relative rotation, but areffreely rotatable as a unit within the ring'2l 'and associated elements.

Obviously, the arrangement of the. flanges 29 and 35 and associated elernents prevents end of axial play in the'spou i351 Suitable screw driver slots or thelike' rn he provided'in the outer end of the in'ell wh a '4 Nqve 'm eesar vf .ed wh c ma e it possible. to urn the spigot on except when the discharge extensi gnfs l is directed fully upwardly or fully downwardly.

The ar an em nt issue t at h o ve 45. is tively'sha llow atits'longitudinal center, as shown at 4 6, and relatively deep at its opposite ends 41. Thebottom of the 'grp ove 45 is smooth and gladually inclined frem :the relatively deep ends 4? toward the central" shallow portion 46 or the groove, Figure "The valve body H is provided in the bofttom 2 of serew-threaded recess 25 with a smalLtranSvers'e r pening or b cre'4ll extending parallel to the longitudinal axis of rotation of the bearing sleeve 35 and intersecting the groove 45. The inner end of the bore 48 leads into a reduced opening pr bore 49, in turn leading into or intersecting the screw-threaded bore I41 Mounted within the bores 48 and 49 for reciprocation is an axially shiftable pin 50 including an integral collar orwasher 5| which is slidable within the bore 48. Acompressible coil spring 52 surrounds the pin {50 between the collar-5| thereof and theinnerend or bottom of the bore 48, as showninliigure 2. This spring 52 serves to constantly urgethe pin 5| toward the bearing sleeve 35, and thelouter end of the pin constant- 1y engages within the arcuate groove of the bearing sleeve. The screw-thread of the valve stem I5 is provided at one point only with a radial notch or detent 53 adapted to receive the inner end of the pin when the spigot is completely turned off and the washer 2| seated upon the seat 20, Figure 2. In all other open or partly open positions of the valve stem l5, the inner end of the pin 50 rides upon the outside diameter or periphery of the screw-thread on the valve stem l5, asshown in Figure 1.

In use, the valve stem I5 is operated by the handle, not shown, in the usual manner, for turning the spigot off and on. When the discharge'extension 3| is directed downwardly, Figure 1, the spigot serves the usual purposes for washing the hands or the like. When the dischar'ge'ext'ension 3| is directed upwardly, shown dotted in Figure 1, the spigot serves as a convenient drinking fountain, the use of which will eliminate the necessity for glasses, cups and the like in bathrooms, train compartments, public lavatories and the like.

' When the valve stem I5 is completely closed, Figure 2, and the spigot is accordingly fully shut off, the detent or notch 53 registers with the reduced bore 49 and may receive the inner end of the pin 50. The spout or nozzle 33 may nowbe turned upon its longitudinal axis, togetherwith the bearing sleeve 35, and when this occurs, the pin 50 willbe shifted axially into the notch or detent 53 when the outer end of the pin rides over the central, shallow portion 46 of the groove 45. This condition is illustrated in Figure 2 wherein the extension 3| has been rotated 90 from its upward or downward position. Thus,

when the spigot is completely shut off, Figure 2, and only when this condition exists, the spout 35 may be turned so that the discharge extension 35 may be directed either upwardly or down-' wardly, as desired. When the extension 3| is'in either the upwardor downward" position, the outer end of the pin 50 will be engaged in one of the relatively deep ends 4! of the groove 45, and the spring 52. will accordingly shift the pin axially outwardly, so that the inner end of the pin disengages the detent or notch 53, Figure 1. When this occurs, thevalve stem l5 of the spigot may be rotated for turning on the spigot to the desired adjusted position. It is thus seen that the spigot may be turned on only when the discharge extension 3| of the nozzle 35: is directed either downwardly or upwardly. In any partially open or fully open position of the valve stem l5, the inner end of the pin 50 ridesupon the periphery or outside diameter of the valve stem screw, as shown.

My spigot is highly simplified, compact and very easy to manipulate. The spigot is well adapted for all conventional usages, and the drinking fountain feature provided by it is highly advantageous and sanitary. From the outside my spigot presents the appearance of any other conventional lavatory spigot or the like.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
