This invention relates to household plumbing fixtures and 'has particularly reference to swin spout mixing faucets, the inveiifiioh'being directed to certain improvements "in the "manner of assemfbiing the spout with and mounting the same to swing relative to the faucet body and to the means for effectively sealing the spout against leakage a't'it'he region of its connection with the 'faucet'body "The invention broadly comprehnds a simple and effective .means of connection between the faucet body and spoutwhich when assembled permits 0f afllim i ted swinging movement of 'thespout with reference thereto, while preventing disas- .sembly thereof without first remd ing the bohiie't's of the valved inlets of the 'faucetbody 'tothereby minhn'ize the likelihood of surreptitious 'r'emoval of the spout elements from the fixtures. ,Animpontan't feature of the invention consists in the employment .o'f a simple threaded connection between the spout and faucet :body 'whi'ch greatly facilitates the'labor of 'asseinbly whilepermitting oi the use o'fl'an elastic fgasketwhich "is so associated with'the spout and 'faiic'et body :as to efiectually seal the same against leakage at their juncture, thereby avoiding the necessity of resorting to expensive s'tiifiing boxes and packing glands and thelik with the attendant requirement to frequently renew the packing andstoffin As a :further feature, the invention comprethends ai swing spout mixing {faucet structure "in which the tauoet body and swinging spout at "the regions of their threaded connection may have portions or inserts fashioned of a Idifferentma- & terial or ial'loyvfrom that of the remainder of the spout and body to provide for a non-corrosive, wearresisting connection. 7 7

With the previously enumerated and other objects in view,'theziollowing specification setsforth r the "inventionf-inigreater detail, while the claims mark out and define the scope of the invention, the structurebeingillustrated in the accompanying drawing, in which: i

Fig. 1 is a fragmentary front view of a swing spout mixing faucet constructed in accordance with the invention, showing the spout swung to the limit of its movement in engagement with the bonnet of the right hand valved inlet end of the faucet body, the medial outlet portion of the body and intake end of the spout being broken away and shown in section to disclose the sealing gasket.

Fig. 2 is a similar view showing the spout swun to the limit of its movement in engagement with the bonnet or the left hand val ved in-let or the faucet body. V V

Fig. 3 is {a perspective view or the insert nortion'at theinlet end of the spout.

Reierrmg to the drawing by characters of reierence, A esignates generally the body-of a swing spout mixing 'fancc't which is of elongated tiibular formation and rovided with a longitudinal passage I'D 'defining' a mixing chamber, the opposite ends of which communicate with the valved inlet ends defined by enlarged portions H and I2 at theopp'osite ends of the "faiicetbody and constitiiti'ng' valve casings over "whichvare threadedly engaged "the usual banners I3. The medial portion I4 of the body A is enlarged to provide a boss which is formed with an inner threaded outlet bore l5-"tlre innermost end of which'opens into the mixing chamber or passage f0 and the outer end of which communicates with the innermost end of an enlarged outer bore Hi opening at its outer end through "the outer surface of the boss or emerged medial portion of the body. This defines fa shoulder ll at the juncture of the inner and outer 'bore's -l-5 and T6 which shoulder is disposed withi-nt'he confines of the boss or enlarged medial ortion M adapted to serve a purpose wljichis hereinafter explained.

The spout, designated generall by the referencefchaira'cter *8, includes an elongated tubular shank portion 2 0 havin'g-a downturned outer free outlet end no n2! andanang'ulated inner intake end "having a reduced depending trunnion ortion 23 of a diameter to snueiy -'fit within the outer 'b'or'e 16 "of the faucet "body aA re'd'uce'd a1 portion protrudes from the trunnion n =23 and is formed with a still 'r-urther red uced 'k ter i'ofly flrraded "eXtlelthity 2'5 en ageable "Within-thethreaded inne'r bore 1'5 to efiec't rotatory connection between the spout B and faucet body A and to establish communication between the :a'nd mix ng chamber or pas- {saQed-t, ashooideme being defined at the Junctu i e of the reduced terminal -21 with the t1-u'na ien "2 3.

An elastic gasket 21 of rubber or an equivalent material is provided, the internal periphery of which is of a size to snugly fit around the terminal 24 and said gasket is interposed between the faucet body shoulder l1 and the spout shoulder 26 to lie within the outer bore l6 of the faucet body when the spout is assembled therewith. This assembly is accomplished before the bonnets are applied to the end portions II and I2, it being apparent that the reduced threaded extremity is engaged with the threaded inner bore l5 and the spout rotated a multiple number of turns until the end face of said extremity is substantially fiush with the inner end of the inner bore I5, as shown in Fig. 2. It is evident that the outer free outlet end portion of the spout B clears the upper faces of the end portions l l and I2 during the assembly but upon emplacement of the bonnets l3, the same act as stops disposed in the path of movement of the outer end 2! of the spout B, thus serving to limit the same to swing: ing movement therebetween. The gasket 21,

which is of such a length that it will be main-- tained under compression at all times after the spout B is assembled with the faucet body A and subsequent to the application of the bonnets I3, will have sufficient longitudinal expansive action to effect a seal at all times thereby compensating for the slight relative movementof the shoulders I1 and 2 6 toward and away from each other due to the threaded swinging connection between the spout and body. As illustrated, the normal outer diameter of the gasket 2'! is slightly less than the inner diameter of the outer bore [6 to afford a clearance space for the radial outward expansion of the gasket as it is compressed longitudinall between the shoulders I! and 26 during their movement toward each other when the spout B is swung from the right hand position shown in Fig, 1 to the left hand position shown in Fig. 2.

What is claimed is:

1. In a swing spout mixing faucet, a faucet body defining a mixing chamber and having inlet valves at the opposite ends thereof including removably associated valve bonnets, said faucet body having an outlet intermediate the ends thereof, a spout having an intake terminal threadedly engaging said faucet body outlet and communicating with the mixing chamber and plied to the inlet valves serving as stops to prevent complete rotation of the spout and to limit the same to swinging movement therebetween.

2. In a swing spout faucet as set forth in claim 7 1, in which the spout intake terminal and faucet body outlet are respectively formed with spaced complementary shoulders located within the confines of the outlet, and an elastic sealing gasket interposed between said shoulders so as to be under compression and impinged thereagainst in any relative position of the spout with reference to the faucet body between the limiting stops defined by the inlet valve bonnets.

3. In a swing spout mixing faucet, a body defining a mixing chamber having valved inlets at the opposite ends thereof and a recessed outlet intermediate said ends, removable bonnets carried by the valved inlet ends of said body, a spout having an outlet end and an angulated intake terminal threadedly engaging within the recessed outlet of the body and communicating with the mixing chamber, the valved inlet ends of the body being so located as to clear the outlet end of the spout to permit of complete and multiple rotation thereof for engaging the intake end thereof with and disengaging the same from the faucet bod during assembly and disassembl of the spout and body, said valve bonnets being so located on the valved inlet ends of the body as to intersect the path of movement of the outlet end of the spout to serve as stops to limit the spout to swinging movement therebetween when the bonnets are applied.

4. In a swing spout mixing faucet as set forth in claim 3, wherein the recessed outlet of the faucet body is formed with an inner reduced threaded bore and an outer relatively larger bore defininga shoulder and wherein the intake terminal of the spout is formed with a reduced threaded extremity engaging the inner bore and with a larger trunnion portion fitted within the outer bore and defining at the juncture with the extremity a shoulder complementary to the outlet shoulder, and an elastic sealing gasket located between said shoulders and maintained under compression in any relative position of the spout with reference to the faucet body between the limiting stops defined by the bonnets,

5. A swing spout mixing faucet including an elongated hollow body defining a mixing chamber, an outlet boss intermediate the ends thereof having a threaded inner bore opening into the mixing chamber and having a relatively larger outer bore communicating with the inner bore and opening through the outer surface of the boss with a shoulder defined at th juncture of said bores, a spout having an angulated end portion respectively forming a trunnion fitted within the outer'bore and a reduced threaded terminal engaging the threaded inner bore with a shoulder defined at the juncture of said trunnion and terminal, the shoulders of said spout and bore being spaced apart, an inlet valve casing at the opposite ends of the faucet body so arranged as to permit of multiple rotation of the spout for threadedly assembling the samewith the faucet body, valve bonnets removably associated with the inlet valve casings and normally disposed in the path of movement of the free end of the spout for preventin disassembly of the spout and serving as stops to limit the spout to swinging movement therebetween, and an elastic sealing gasket located between the shoulders so as to be compressed therebetween and maintained under compression in any position of the spout with reference to the faucet body between the limiting stops defined by the valve bonnets to seal the intake end of the spout at its junc ture with the faucet body.
