To all 'iv/tom t 'may concern Be it known thut l. l.\'rnu'k .\l,\noxr.v. n citizen of the United States, reddingq nt lortlnnd. in the eountv ot (hunherlutul und Stute olI Muine, hure invented rertuiu new i und n eful lm|novements i`n Devires for Maintaining :i llnlt'orm Deltverv of inter lowing is :L lpeeilirnlimr My invention relzttes tol improvementv in device4 for muiutniniugr :t uni'l'ornl deliver)v of water under vnr vin; lr prewure. und l have illustrated the unie n upplied to what i popularly culled l\:|uit:|r,v drinkingr l'ouutnins, hut the use ol the :'ippnrutuh in not limited to this pui-pme und npplieunl dow not intend to limit itxV use ill :tnv wuv other than :is is hereinn'l'ter yset out in the rlnium.

In theI druwingh4 herewith :ieeompnnying' und foi-Illing n pnrt of thi npplientiou,

Figure 1 is n sectional view, pnrtlv in elevni tion of my improved nppurntus: Fie'. is n detnil section showing the menus for preventing'` the witter from spraying when the delivery end o1 the, nozzle is eloxed; Fi". 3 is n transverse Sectional view tnken 'tinlinl X--X, Fig. 1, nud ltg. ll. is n detnil s towing' side und end views of one of the regulating?` valves.

The same reference elntruetew,l indicate like ports:y in the several ligures.

In an apparatus for thedelivetv of waiter from a supply under prenten-e, which pres;- sure is subject to variations due to any cause, and especially in drinking fountains of the class designed for the drinker to hike.

the water directlyr into the mouth from n column of water, it is found to he' :u'l'vnntw geous to provide means 'for maintaining the column of writer nt. nsuhstnntinlly uniform pressure. Appliezints device is especially designed for this purpose. To this end, it consists of n homing A. n couplingr B ndnpted to connect. it. with :t witter supply. n verticnl spindle (l. mounted in Suid coulpliug undv provided with one or more vertieuports l). The lower end of the spindle tu eup-shnped, as: seen nt 1".. :intl lending thereonto'lnre ports F in the vertit'nl wnlls ther'eoli und in the 4top nre, ports (i opening` into the ports I) in the spindle, the lower portion ofthe ports l) is of greater enpneity thun the upper )o1-tion. Surrounding unds'lidalile upon tie spindle C is n. ring I[ provided with n, packing I and u. spring receiving reeess .l in the top thtlireof. .ihove the ring ll und nu'rounding Qpindle U is n l#top li hurinr :t pm kiner l. held in plut-e hy n perkinn' ring: M.

'l`he homing: hue u deliverv opening l in the top thereof lending' out of'n ehulnher (J nhove th:` top ot' the spindle. .inv lQuituhle delivery nozzle univ he inserted in the opening' l in the top of the housing. l have illustrnted it to he used in eonneetion with y:t snnitnry drinkin;lr fountain. und to this end l hnve provided :t relohe-Juqwd terminut ll nud :t deliverv nozzle S extending! from the opening! l lipoug'h the termin-.1l h. lt' the nozzle H ifier'livertienl. the water would l'ull len-l.' u|ton ,`the terminal It und r-:tuse more or le4 `\putterin;1. rl`o uvoid thiv olijeetion. l ruu e the nozzle S to he defleeted -:ouie\vh:tt from the vertirnl line. of.: seen :it 'l`. so thut thehvnter i uin1 thert-I'rom will :tlm |:e tlelleeted from the vertiezil line sullirientlv to l'nll just. out.ide the terminal. rl`he :tmount of wnter to he delivered through the portl vl) in the spindle :1nd through the ports in the l*top mnyphe .uried :1t will by luitnhle adjusting devices. ,-:l1o\vn..l hnve provided the top K und lpindle (V. with .'uljustinglr wrews V having on their inner ends' thin hlnde l \V adopted to project into the ports in the stop and spindle respectively, ivherehy the turning of said screws causes the hlndes iV to close more orlesx.l of the ports, according to the extent snid screws nre turned.

To prevent witter from sputtering if the end ofn the nozzle. is closed I provide the nozzle S inside the housingwith ports 1 extending diagonnll ti wnrdly. This does not interfere with tie r elivery of the water through the end. of the nozzle nnd if the nozzle is closed., instead of the water squirtingr` out, it flows hack through the opening l into the terminal R und thence throughthe orts 2 to the outside.

'1 le operation of my `improved device is :is follows: The water entering the chamber tl'irough ports l1` pannes thence into the port` in The spindle und, when the presure is noi-nml, the limiting ring II is moved nlp wardly 'against the stop K so ns to close t e PWH 0 in the Atop und then all the witter delivered will he through the. ports l) in [f the normal. pressure is dis- A downwardly, thus o enin the ports U so that water will be de ivere to the nozzle, not only through the ports D in the spindle but through the orts O in the stop.

Havin thus drscribed my invention and its use, claim:

1. In a device of the character described, a housing, a spindle mounted therein and provided with vertical ports a stop secured to the top of the spindle and provided with vertical orts, a floating ring positloned be lour sai stop, and a spring inter osed between said sto and ring and ten ing n ormally to hold t em apart, sa1d iloat1 ng ring being adapted to be held agalnst the stop and to close the ports therein when the pressure is normal and to be forced away to open said ports when the pressure is diminished.

2. In a. device of the character described, a housing, a spindle mounted therein and provided with vertical ports tapering up' wardly, a stop secured to the to of the s indie and provided with vertice ports, a

eating ring positioned below said stop,

land-a spring interposed between said stop und ring and tending normally to hold them apart, said floating ring being adapted to be held 'against the stop and to close the ports therein-when the pressure' is normal and to be forced away to open said ports when the pressure is diminished.

3. In a device of the character described, a housing, a spindle mounted therein and provided with vertical ports, a stop Secured to the top. of the spindle and provided with vertical dports, a' floating ring positioned below sai stop, a spring intel"- posed between said sto 'and ring and tendmg normal] to hold t em apart, said iioating ring being adapted to be held against the stop and to close the ports therein when the pressure is normal and to be forced away .to open said ports when the pressure is diminished, and means for regulating the capacity of the ports in the spindle and in the stop.
