deceased Application October 24, 1947, Serial No. 781,881
This invention relates to hydrants connectable in a water supply line and the principal feature and object of the inventionis to provide a hydrant so constructed as to permit water in the hydrant, upon closing the valve, to automatically drain from the hydrant and thus prevent freezing.
The main object of the invention is not only to prevent freezing but to prevent a cross connection between the waste outlet and the water supply whereby ground water could be syphoned through the waste opening during periods of operation and polluting the water supply.
A further object of the invention is to prevent ground water being syphoned through the waste opening during periods of operation and thus polluting the water in the supply conduit.
By the arrangement and relationship of parts as hereinafter more fully described water remaining in the hydrant upon closing the valve accumulates in a chamber below the frost line and is therefore particularly adapted for use in the North and South Frigid and Temperate Zones.
A hydrant embodying my invention is shown in the accompanying drawing in which- Fig. 1 is a vertical section of the hydrant.
Fig. 2 is a vertical section showing a different form of chamber into which the water in the discharge line may accumulate. y
Fig. 3 is another form of drainage chamber having the same function as that shown in Fig, 1.
As will be understood more clearly from Fig. l a water main is indicated at I and lies substantially in a horizontal plane. To the water main is connected an elbow 2 having a threaded end to receive the threaded end of the water main I and the opposite end 3 of the elbow is positioned to receive the threaded end of a verticaltubular element 4 threaded to receive a tube 5 which extends to above the ground level indicated by dotted lines 6.
The tubular element 4 is provided with a valve seat 'I and a valve 8 is provided with a stem 9 which extends to above the ground surface. On the upper end of the tube 5 is a plate I9 apertured to receive the same and a plate II is secured to the plate I and seats on the upper end of the tube 5. At the upper end of the stem 9 is a knob I2 by means of which the stem 9 may be rotated. Said stem 9 is provided with a threaded aperture above the valve seat I to receive an enlarged threaded portion on the stem 9 and on the lower portion of the stem 9 are preferably two cupped washers I4 and I5 to prevent water accumulating in the tubular element 4 and the tube 5. The lower end of the tubular member 4 has a tubular threaded portion I6 on one side to receive one end of the elbow I'I the opposite end of which is threaded to receive a nozzle I8 and on the vertical end of the elbow II is a chambered member I9 apertured at its lower end to receive the nozzle which is provided with a flange as indicated at 20.
The nozzle has a conical end Aportion 2| on vwhich is seated a drainage element 22 having a chamber 23 opening to the horizontal passageways 24 just above the upper end of the nozzle 2I.
By this arrangement when' the valve 8 is closed, subsequent to use of the hydrant,v any water remaining in the tube 25 may drain back into the chambered element IS positioned in the earth below the frost line.
The upper end of the chamber I9 has a hublike extension 26 internally threaded to receive the lower threaded end of, the vertically positioned tube 2'I and the upp'erend of the tube 2I is likewise threaded in a recess in the lower end of the chambered member 28. The chambered member 28 has the bottom wall 29 centrally threaded to receive the upper threaded end of the tube 25. y y
The plate I0 at the upper end of the tube 5 extends over the upper end of the chambered member 28 and is secured thereto by the screws 30 and3l. The chambered member further has a threaded aperture in the side wall to receive the threaded end of the discharge nozzle 32.
In Fig. 2 is shown a different form of drainage element which includes a chamber #9a correspending to the chamber I9 shown in Fig. 1 and has the same function as that shown in Fig. 1. The drainage element 22a differs somewhat from that shown at 22 in Fig. 1 but has the same function as the element 22 in that the apertures 24a are upwardly inclined in respect to the horizontal and the member 22a has a Venturi-like chamber 33 and the apertures 24a open to the chamber 33 just above the restricted area 34 of the chamber.
The upper end of the chambered member I9a has a hub-like extension to receive the tube 21a in which is the tube 25a having the same function as the tube 25 shown in Fig. 1. The lower end of the Venturi tube 22a is threaded to engage the threaded end of a fitting 20a corresponding :inn function to that of the tting 2i! shown in In Fig. 3 another form of venturi is shown in which the chambered member I9b corresponds to that shown at I9 in Fig. 1 and a tube 40 is threaded in the upper end of the chambered member I9b and a tube 4I is provided within the tube 40 and has the same function as the tube 25 of Fig. 1. The Venturi element 42 in Fig. 3 differs from the venturi 22 of Fig. 1 orV 22a of Fig. 2 in that it has a central chamber 43 having openings 44 therein which have the same function as the apertures 24 in the member 22 as shown in Fig. 1, namely, to permit ow of water: remaining in the tube 4l upon the closing of 'the-main valve corresponding to the valve shown at 8 in Fig. 1. The tube 21 has an opening 45 therein above the ground surface which permits air to flow into the tube 21 asY the water level in the reservoir I9 falls or from the tube 21 Vas the waterlevellrises; This ar.-
rangement prevents a waste of-'water-andpre vents a vacuum occurring in the chamber I8, 19a
4The member 20a has a central longitudinal aperture of cylindrical form and thus differs from that shown at 21 in Fig. 1. In Fig. 3 atube 20c isthreaded for a` distance from its end and is inserted intov al threaded aperture in thevbottom of the chambered'elementlb and a-nut 20d is threaded on the tube 20c and engagesthe bottom -of the chamberedmember |917. A gasket 20ev is providedA between the nutl and the bottom of the chambered element 1 i90.
With either of Vthev forms off the invention shown closing of the main valve 8-permits-Water in the l conduits'v25, 25ct. or- 4I to VdrainV back into thechambered members 19,190., or I9b of the respective forms-of 1the-invention which,as here- `inbefore stated,` arepositioned in the earthr below thefrost'fline. The-device is Aparticularly useful inthe watering. of'lawns.
One of the outstanding requirements fori lowering, lthe maintenance costs of hydrant .operation is that all working parts be yaccessible for Vrepairs at at point above Lthe Aground level.
Itis. believed A'obvious from the foregoingdeiscriptionl that the various `objectsand features ofthe invention are attained irrespective-of: the form of: the drainage members 2222ar or 40.
