This invention relates generally to'hydrants and more particularly to hydrants of the non` freezing type.
Conventional hydrants of the anti-freeze type utilize various means of draining waterfrom the column leadingto the spout ator near the base of the column. These hydrants require a porous lling at the base of the hydrant, thereby requiring the valve in the hydrant to be located a greater distance below the surface of the ground. In these prior devices there has been siphonage of Waste water into the water column when a reduced pressure or vacuum occurred in the water column or in the hydrant supply line.
It is, accordingly, an object of our invention to overcome the above and other defects in nonfreezing hydrants, and it is more particularly an object of our invention to provide a nonfreezing hydrant which is simple in construction, easy to install, economical in manufacture, economical in cost, and elcient in operation.
Another object of our invention is to provide a non-freezing hydrant which requires no drain or other connection to the outside thereof thereby eliminating any chance for cross connection between a drainage line or water and supply line.
Another object of our invention is to provide a non-freezing hydrant utilizing an ejector.
Another `object of our invention is to provide novel means for mounting the water column of a non-freezing hydrant a sufiicient distance below the ground to prevent freezing.
Other objects of our invention will become evident from the following detaileddescription, taken in conjunction with the accompanying drawings, in which:
Fig. 1 is a vertical sectional view illustrating an embodiment of our novel non-freezing hydrant;
Fig. 2 is a fragmentary vertical sectional view showing a check valve in the vent opening in the l water column;
Fig. 3 is a view taken on the line 3-3 of Fig. l;
Fig. 4 is a view taken on the line v4--4 of Fig. l;
Fig. 5 is a fragmentary side elevational view of the cam lever in a position to close the valve in our novel hydrant; Y
Fig. 6 is a fragmentary side elevational view of the cam lever in a position to open the valve in our novel non-freezing hydrant;
Fig. '7 is a fragmentary sectional view showing a modified form of our novel non-freezing hydrant; and
Fig. 8 is a view taken on the line 8-8 of Fig. 7. Referring now to the drawings, Fig.':1 shows a 2 claims. (ol. 137-282) base plate I-having azdepending flanged portion 2 for receiving a valve sleever 3 andY a depending flanged portion 4 for'receiving a water column 5.1 The base plate I is preferably disposed substantially at the ground Asurface The valve sleeve 3 has a. threaded portion 6 on theglower end thereof forthreadably engaging Lthe internally threaded portion1 of fitting 8 having a vertically disposed aperture 9 injaxial-alignment With the sleeve 3, and aesecondv aperture Ill leading to a Athreaded aperture I I- forthreadably engaging a threaded nozzle-I2. The upper end.
ofthe sleeve 3 isvthreaded at I3 for threadably engaging an internally threaded flanged cap member I4 having acentrally disposedaperture I5v for receiving a rod- I6 which .extends along the axis of the sleeve A3 downwardly therethrough. The lower end of the rod IS .is engagedto valve stem I1 by means of sleeve I8 and pins I9. Cylindrically shaped washers 20 having intermediate sealing washers 2|v are disposed on the stem I1 between collar 22 and a nut 23 engaging threaded portion 24 of the stem I1. The 4washers 2l seal the aperture 9 in fitting 8 and prevent passage of water therethrough The lowerend of the stem I1 hasV a` seatingmember 25 disposed between collar 26 anda nut 21 threadably engaging the lower threaded end of the stem I1. The

tting 8. It will thus be evident that air passing from the surge tank 4l will pass throught-,he apertured portion 42 thereof, through aperture The lower end of the apertured portion 42 has an aperture 43 leading intofchamber 44 in the the fitting 8 to shut off the supply of water from the supply line 29. The check valve 64 then seats on the wall member 62 to stop the back flow of Water from the hose connection 82 whereby water in the water column passes downwardly and disposes in the surge chamber 4l whichis below the frost line. Air is 4vented from 4the surge chamber 4| to the vent42A and a vent 43 to the valve sleeve 3 which also has a vent 45. It will be evident that no vent is absolutely required in the surge chamber 4I in order for our novel invention to function efliciently in that Awhen water is withdrawn by the nozzle I2 and arcuateshaped member 55 from the surge cham- 43 and chamber 44 to the interior of the valve sleeve 3.` Valve sleeve 3 has a small air `vent45 near the top thereof. The surge chamber 4I has the upper internal portion thereof threaded at 45 for threadably engaginglangedexternally threaded cap member 4-1.' The cap memberlli has a flanged portion 48l`disposed'centrally thereof withfinternal vthreads 49 for threadably engaging"k an arcuate lshapedmember 50 having an arcuate 'shaped centrally disposed aperture" 52 axially aligned with thefoz'zlemember l2. The lower end of the memberSGeXtends "a1 suiiicient distance below the -uppe'rlend of the nozzle member l2 tov providechangs of pressure (Venturi eifect) as waterpasse's through thenozzle member l2 to the arcuate shaped member 5). The upper end of the arcuatev shaped member 5ll`has a threaded portin53 'for` threadablyengaging 4' the threads in the cap member -4-1. The lower end of thewaterr clumrib has threads55 for threada'bly engaging" the threads lll-lv in the 'cap member 41. The upper end -of thev sleevev 5 has threads 58 forthreadably engaging the threaded angedportion 59 of 'globular member 60.A The upper end of the member '-60Y hasv external threads @6| "for connection to anyv conventional -hose coupling member 's uch as" coupling member -8'24 shown in 7 dotted 4 lines. rhe' member 60 has la fdividing wall' 62 with la centrally -disposed aperture *63 lladapted to be closed by a check Yvali/'e154 whenl there is no flow of waterV to- 'the hosefcoupling 822 The check valve 64 has afstel` 65 journalled inapertured web 56 disposed inthe upperfpa'rtof the member 6i);V An air ventB'! isprovided in the member lfto permit airto' be bledfro'm the member 60 and column'f 5.- In ',lig. 2;"I` have shown the globular* member Ell withian 'airvent 13, and a checlr valvemember- '(4 with sa spring- In operation, 4when "my novel 'nongfreezing hydrant is in a position as shown in Figi Y1; water is disposed in the'surge 'tank -4lrup to"` the top, or substantially thetop of the vent member 42. When the cam lever 35v is rotated 90 degrees, valve seat is lifted from the -seat 28 of the fitting 8 wherein water passes lthrough branch l0 of the ltting 8, through `nozzlel l2, member 5l) and water column 5 and out 'through hose `connection 82.I When water. passes 'through the nozzle I2 and arcuate 'shaped member -50 a .Venturi effect' results whereby water-*s `drawn from the surge chamber 4lr up throughthe'water column 5 to the hose connection :82, thereby leaving the surge chamber: 4I' ina substantially 'evacuated condition. When it isfdesired 'to Vshut off the supply of water, thecam lever israised to an upright position as-shown inzFig. 1` whereby the seating'member 25: Yseats on'the'seat' 28iof ,ber 4lf,vacuumwould be producedin the surge chamber 4l if there were no air vent thereby assisting jto returnr water to the surge chamber 4l when water ceases to pass through the nozzle l2;
It will be evident that the nozzle l2, and arou- 'ate shaped member :5.0 maytake manyv diierent formsV and thesurge cham-berm need notr necessarily be a part of the fitting 8.1Tl'1'eJsurge chamber' 4i is preferably' disposed below the frost line and is large enough to' 'contanall water inwatercolumn.'y I
'y In Figs' andV 8, weshow a modified form -of globular valve on the' upper endf-of the fluid supply line 5.` The .globular member 8| has van apertured central wall portion 83 for seating a check Valve 84 with a downwardly extending stem 85 and an upwardly extending stem 8l journalled in web 88.' A spring` member 86 urges the check valve 8411i sealing relationship with 'the' apertured wall portion 83 of the globular member 8l.' A lever 8S pivoted at 5i) has 'an outwardly-extendingY lever arm 9! for engagement with anoutwardly extending lug S3 on they cover member 92 disposed on the base member 8e. vIt will thus be evident that'whe'n the cover 92 is closed, the check'valve 84will` beforced-upwardly by the lever 89 through the engaging lug 93 causing the fluid in'uid line 5 to be forced below the frost line and into the surge chamber 4I.
ItV will be' evident from the 'foregoing vthat we have' provided "a novel nonfree'zing vhydrant which requires no outside drainage connections thereby requiringnol loosell around `the base of'the hydrant, which "Is `elcient inloperation, and'which prevents any :cross'c'onnection between a sewer line or subfsurface seepage water andy a supply water line.` .Y f
