If'a .liquid level actuatoris employed to control draining of the-tank,-the'n'the timei'nterval may be regulated by the'rrate ,offfilling of the tank. Ithas been common "practice 1 to employ float actuated valve mechanisms and tilting tanks for this purpose andualso siphons dependent on the rate of flow of the liquid into the tank. "The presentinvention relatesto a siphon which is started intotac- 2 tion when a predetermined liquid-:level is reached in thetank'and is not dependenton the rate of flow into the tank." 1
' The objects of this invention: are topro- 'vide an automatic tank having'any or all of the following features: no moving parts;
an automatic siphon of novel character; and .7
an automatic siphon which will permit a'slow filling of the tank. Theseobjectstogether with other objects ":13 'and'corresponding accomplishments are obtained by means of the. embodimentsof my drawings, in .which 1 'Fig.-.1-is a' sectlonqthrough an automatic invention illustrated. in the accompanying -35 flush tank equipped with my'improved siphon shownv in elevation; Fig.2 isa section as seen on the 1ine-2 2 of FigllyFig. 3 is a. section as seenon'jthe line 3l3gof Fig.1;
and Fig: 4. is a diagraph-ic view'to. illustrate the operation of the siphon. Referring more particularly to the drawing, a tank 5 is-provided with an. outlet coupling 6 adapted-to besecured to a .fiush. pipe. A-filling. pipe line '7 has a1lege8 extending 45 close tothe bottom. ofthe tank and afcontrol [:valve 9-is" providedfor. regulating the" rate p of filling of the tank.a-"Gnnec ted .to; the out let coupling is a siphon consisting of In dis charge limb 10 and a receiving limb 11. -The 7 5 0 limb 11 is. extended;- upwardlyiadjacent: j
'the'trap Othereby trapping airin the curve B. The level of the liquid -in limb, 13 .will j inlet toforni a limb 12 which joins with l a downwardlyextending limb 13. Limbs- 10 and ll-fo'rm the main siphon marked A and limbs Hand 13' form an auxiliary siphon marked-13.;- Limbs 11. and 12 form a liquid '55 trap C. I For the purposejofmaking the si-. phon compact, the. auxiliary siphon has its limbs'iniaplane at-right angles to the plane- I of the main siphon. I f A startingtube of siphon: form is connected to the top of the curve in auxiliary siphon B, there being abraneh. 14 extending downwardly and connected to a branch '15 which has at itsreceiving end a curve leading to a downwardly extending branch'lfi which is disposed in the boreofthe outlet coupling. The startingtube is preferably a caplllary tube with'an intermediate portion 15 of enlarged diameter sothat itph'asqsub .stan'tially no capillary action in that portion.
An inlet port 17 of small cross sectional area is-formed in the receiving limb l5 forqcoin munication of the limb with the liquid in the tank. o I I i" Referring to F ig. l, the operation is as fol? lows: Liquid enters "thestankthrough the filling tube 8 at a rate :dep'endenttpon the opening of valve 9. The liquid rises in limb v 13 and overflows into limb 12, passing into be equal tothe level of liquid inthe tank less the air pressure of the entrapped airin I I "curve '13. lThe'pres'sure of the air in curve 5 B will be, that equal ,to' the difference in levels of the liquid in the limbs of trap C. Thus, the'column of liquid 'inilin1b13 plus 1 the difference of levels in thelimbs of trapj C i will beequal to the"height of the liquidin' the tank. The level of theliquidjn limbll so will thusbe belowthelevel ofliquid in the I V tank. I-lowever, asthe level of liquid in the tank is'increased, the level of; the liquid in limb 11 increases and eventually will reach the bottom of curve A.; Liquid ill. e t 9 ort l7-in-theair eduction tube and a trap will be formed at the lower curve thepres 1 sure exerted beingsufficient "toseal the port j i 17 againstthe discharge of air as thepressure l at the port is equal to; the level of liquid; in ite the tank less the height of the port 17 above the bottom of the tank. This difierence in levels is such that the pressure is greater than that in the pressure air trapped in curve B. At the same time liquid will rise in limb 15. Finally it will reach the upper curve in the eduction tubeand flow over into discharge limb l6 'anda siphoning actionmilil he started Whichwill cause the eduction of air from curve B so that a siphonic action Will be started in the mains'irihonarid-the tank will be emptied. In order to preventliquid from overflowin from receiving limbf'l5 to dis- Chargeliml) action, I have provided a capillary tube, To prevent thei'capillaryeaction; firomicausing. the
