Application tiled December 16, 1903. Serial No. 185.399. (No model.)

To all whom t 11i/ty con/cern,.-

Be it known that I, J osnrH A. MoCoEMIeili, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soda Arms or Faucets; and I do hereby declare that the following is a full, clear, and exact description et the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part oi' this sjgieciiication.

rIhis invention relates to improvements in soda arms or faucets for soda-water fountains adapted to deliver a liquid charged with or partly vaporized or an unvaporized liquid therethrough, dependent upon the adjustment ot' the operating-lever.

I'Ieretofore it has been diilicult to adjust the various parts ot' the mechanism to prevent leaking, and it has been a common fault that when satisfactorily adjusted the constant operation of thedevice tends soon to vary the adjustment, with the el'Iect oi permitting leak age. The adjustment of the valve upon its seat usually has been accomplished by means ot' a set-screw which, engaging through one of the lateral arms ot' the operating-lever, bears against the valve-closure and forces the same upon the seat. W'hen thus constructed, the set-screw having a small bearing upon the valve-closure permits the same it slightly loose or a little worn to be 'forced away from the seat or slightly tilted by pressure, permitting leakage.

The object ot' this invention is to provide a strong', simple, and durable device ot' the class described, provided with adjusting' means so constructed as to positively hold and lock the mechanism in adjusted relation after having' been adjusted, permitting the adjustment to be varied only to increase the pressure of the valve-closure upon the valve-seat.

It is also an object ot' the invention to provide a broad bearing upon the valve-closure, insuring approximately even pressure over the entire area thereof and uniform wear up'on the moving parts.

Ihe invention `consists in the matters `hereina'lter described, and more 'fully pointed out and delined in the appended claims.

In the drawings, Figure l is a central transverse section ot' a device embodyingimy invention. Fig. 2 is an inner i'ace `view oi' the ad justing-nut and valve-closure therein. Fig. 3 is a fragmentary end elevation oit' the fixture with the valve-closure and adjusting-nut removed. Fig. i is a perspective view ot the valve-closure. Fig. 5 is a perspective view of the lever end adapted to engage the valveclosure.

A indicates the main faucet-body rigidly secured on the outer end ot a delivery-pipe a, leading from the tank, reservoir, or fountain, and which communicates with a central bore in said faucet-body, opening' outwardly through the center ot' the valve-sait- Also integral with the faucet-body is the delivery-pipe a', which may be oi' any coniiguration and is provided witha plurali ty oi' longitudinal bores in the usual manner, one oi which, ai, opens centrally through and is restricted iin the nozzle a2, and the others of which, a5., open laterally oit said nozzle, discharging into a deflecting-channel as, surrounding said noz- Zle and within the shell A', which extends below said nozzle a and affords an outer nozale. Said :faucet-body on one end thereof is faced to provide a i'lat valve-seat, in which is secured a washer ot' indurated fiber, rubber, or other suitable material B, through which is provided a central aperture communicating with the central bore oi' the faucetbody. Adjacent to the center oi' said washer is provided a plurality oi other bores corre spending' in number with the `number of pas sages in the delivery-pipe and each ot' which communicates with one oi" said passages, which open laterally through said valve-seat. Surrounding said seat and concentric with the faucet-body is a circular flange which extends longitudinally oit' said body and is screw threaded externally and within which `lits the valve-closure C. Said valve-closure C is cylindric in iorm and on its inner face is provided with a peripheral flange c, in which lits a washer o, oi'l leather, liber, rubber, or any suitable material, which, as shown, is provided with a central aperture c2, which registers with the passage in the central bore in washer B and also communicates through a passage in the valve-closure with an aperture c3 therein, positioned to register with either of the laterally-disposed apertures in the ,valve-seat. It follows that when the valveclosure is turned in one direction to the positeeth or projections CZ'.

tion indicated in dotted lines in Fig. 3 the passage in the valve-closure registers with the central aperture in the seat and with one of the laterally-disposed apertures, and when turned in the opposite direction at approximately a right angle with the former position it registers with the central aperture in the seat and the other of said laterally-disposed apertures. Means are provided for holding said valveclosure in positive adjustment upon the seat comprising a bur or internally-threaded nut D, which engages the threads of said flange and is provided on its outer end with an inturned iiange d, which bears on the valveclosure near its periphery. Said flange d provides a reduced circular aperture at the center, as shown in Fig. 1, adapted to receive the cylindric pivot-bearing e of the arm E of an operating-lever E of the usual or any desired type. Extending diametrically across said `pivot-bearing is a rectangular projection e',

adapted to register with a complemental seat in the outer end of the valve-closure, as shown in Fig. 4, and which affords a long bearing for the lever in turning said closure. Said bur or nut D may be of any external conformation orornamentation and is provided on its inner face with radially-disposed ratchet- Seated in the body A between the flange b and an outer flange is a latch or bolt G, which, as shown, is angular at its outer end and which at its end adjacent to said bur is shaped complementally with said teeth or projections to engage the same and, as

shown, is angular in cross-section and seated in a socket in said body and provided with a stem g, which projects outwardly at the opposite end of the body and is provided with a ring or other suitable means for manual engagement to enable the latch to be retracted. As shown, the aperture for said bolt or latch is reduced in size where the end of the stem passes therethrough, and a pushing-spring g is secured in the seat and acts normally to hold said latch in position to engage said teeth, thus permitting the nut or bur D to be turned inwardly to produce any desired degree of compression of the Valve-closure against the valve-seat, while said bolt or latch G acts to hold said bur or nut from being retracted either by accident or design without first retracting said latch. On the end of said body opposite the bur D is provided a washer B', shaped externally to afford a finish corresponding with that of said bur or nut and of -a diameter equal thereto and suflicient when in place between the arm E2 of the lever E and the body to cover the inner end of said bolt or latch G. Said washer is provided with a central aperture extending therethrough adapted to receive a bolt b2, which is shouldered adjacent its head or outer end and adapted to bear positively against said washer, as shown in Fig. l, thereby bearing the same firmly against the body. The end of said arm E2 is apertured to receive the head b3 of said bolt and is provided with an interior shoulder against which the inner side of the head bears.

rl`he operation is as follows: In assembling the device the valve-closure is seated within the flange b, and the nut or bur D is screwed downwardly on said flange until the pressure of the inwardly-directed flange l at the outer end of said bur bears with suliicient pressure upon the outer end of the valve-closure to hold the same firmly to the valve-seat. The

latch or bolt G engages behind the teeth or ratchets of said bur or nut and acts to hold the same from retraction or unscrewing. The tongue e of the lever end E is then inserted in the complemental seat in the valve-closure, with the rounded pivot or cylindric bearing e of said lever end seated in the aperture in the outer end of said nut. The washer B' is now slid into position covering the bolt or latch G, and the bolt b2 is inserted through the lever end E2 and said washer and screwed into the faucet-body, as shown in Fig. l, the inner shoulder of said bolt bearing against the washer, and the friction caused thereby acts to hold said bolt from turning when the lever E is actuated. Having assembled the device and connected the same with a suitable fountain or reservoir by means of the pipe a, should the device ever require adjustment-as, for instance, in the event of the washers b or cvbecoming more or 'less worn-the same may be readily brought into perfect bearing by turning the nut or bur D upon the iange CZ, said latch permitting the same to turn only to bring the valve-closure into more positive bearing upon the seat. Should it ever be necessary to renew said washers, it may be readily accomplished by removing the bolts b2 and washer B, after which the latch or bolt G may be retracted manually and the bur or nut D removed, exposing the valve seat and closure to enable necessary repairs to be made. Obviously as the flange l bears with uniform pressure on the outer end of the valve-closure near its periphery said valve-closure is at all times held in unvarying relation with the seat, the only movement possible being the partial rotation due to the movements of the lever. In the devices heretofore used also the continued operation of the lever frequently causes the adjusting devices to be more or less loosened. This can obviously never occur with a sodaarm constructed as described, not only for the reason of the frictional bearing of the bur IIO upon the threaded iiange, but also for the reason of said latch holding the same positively in its adjusted position.

I/Vhile I have described my invention as applicable to a soda arm or faucet, the same is obviously applicable for use in faucets and valves of' many other kinds and descriptions, and I do not desire to be limited either to the exact construction or the specific uses herein shown, as many details of construction may be varied without departing from the principles of this invention.
