' This invention relates generally. to hydra-s and more particularly to hydrants of the man freezing type.

Conventional hydrants of the anti-freeze type util'ize various means of draining water fromthe, column leading to the spout at or near the base of the column. These hydrants require a porous fillingv at the base of the hydrant, thereby requirg ing the valve in the hydrant to be locateda-ereater distance below the surface of the ground. Con= ventional hydrants of the anti-freeze type have. the valve located below the frost line. This valve is connected by a suitable pipe or other conduit means with the surface outlet and utilizes vari-- one means of draining water from the "conduit at or near the valve in the base when the hype,

drant valve is closed. In these Prior devices there has been "siphona-ge of waste water and sub -v surface seepage water through the water column hydrant which is simple in construction, easy to install, economical in manufacture, economical in cost, and efficient in operation.

Another object of my invention is to provide non-freezing hydrant which requiresno drainer. 1

other connections to the outside thereof, thereby eliminating any chance of cross-connection between a sewer line anda supply line.

Another object of my invention is to provide novel means of mounting the water column ore non-freezing hydrant a sufficient distance below the ground to prevent freezing. a Another objector invention is to provide novel connecting means between the HOSE CO'flIleC- tionand an anti-freezing'hydrant.

Other objects of my invention will become evi= dent from the following detailed description, taken conjunction with the accompanyin drawings, in which: a Fig. 1 is a vertical sectional View illustrating an embodiment of my novel non -freezing 'hydrant;

Fig. 2 is a side elevational fragmentary View showing the operating lever for the valve of my novel'noh-freezing hydrant; and Y i-F ig. 33 isa fragmentary verticalsectional view of the novel connection "for the end of the hose combined with my novel noh free'z'ihg hydrantfj Referring now to the drawings, Figs. 1, 2;;a'n show obese. Plate! having depending 111a .por-tion'z for receiving 1 surface;

2 a valve sleeve 3 and a de= pending flange portion 4 for receiving a verti cally. extendingsleeve 5; The base plate I is preferably disposed substantially at the grbund I The valve sleeve 3 has a threaded port tion 6 on the lower end thereof and threadably engages the internally threaded hub portion ,1 of fitting 8. Fitting 8 has' verti'cally disposed apertures 9 and It in axialalignment with the sleeve 3 and a branch-line ll having a threaded hub portion 12 for receiving the lower threaded end 13 of sleeve 5-. The upper end of the "sleeve 3 is threaded at M for receiving an internally threaded flange-d cap member 15 having 'a con trally disposed aperture I6 for journalling a valve rod I 1 which "extends axially of the sleeve 3 down wardly therethroug-h. The lower end of the rod l! is engaged to a valvestem M3 by means of a sleeve 19 and-pins 2H. Cylindrically shaped merribers 22 having intermediate sealing washers 23 are disposed on the valve stem I8 between a collar 2t and a nut 25 engaging threaded portion fltjof stem '18. The washer 2'3 seals the aperture 9 in the fitting '8 and prevents'passage of water therethrough. The lower end of the stem I8 has a seating member 28 disposed between collar on stem l8 and a nut 30 threadably engaging'the lower threaded end of the stem I8. The seating member 28 seats on seating portion a: of the f1t ting -8 and seals the aperture In in fitting 8 to the passage of water from a sup ly line 33." A spring member surrounding the rod H is disposed on the upper end of the rod I1 between cap member [5 and a collar 36 attached to the rod I! by a pin 31. The cap member; l6 and the collar 36 have recesses 38 and 39 for nest; ing the ends of the spring member 35. A cam" lever 40, shown. more particularly in Fig. 2, has bifurcated end 4! which is attached to the up:

per end orthe rod [1 by a pin 42. The bottom surface 33 of the cam-lever it engages the cap member 15, and is a predetermined distance from the horizontally extending pin 42 so that the seating member 28 seats on the seating surface 32 of thefitting 8 to prevent the now of water frotn'the supply-line '33 when the bottom surface 43 of the cam lever 30 is in engagement withth'e cap member i t; When the cam lever is moved in eitherni short, a distance to degrees'one side surfaeefllt 6f the bifurcated end 4| offithe cam lever 4'0 engages the top of thecap member, T5. Inasmuch as the surface 44 of the bifurcated end M or the cam lever .40 is a'greater distance (from:

the :pin '42 thanthe bottom surface 43 Of "the bi'vj tor-med end-.41 ortheoam lever. the statin member 28 moves away from the seating surface 32 of the fitting 8 and permits the passage of supply water through the aperture ID of the fitting 8.

The upper end of the sleeve is threaded at 50 to receive a cap member 5| having a threaded portion 52 for threadably engaging the threaded portion 50 of the sleeve 5, a groove 53 for receiving a U-shaped washer 54, and opposed locking portions 13 on the upper side thereof. A cylindrical connecting member 60 is adapted to extend operating said seating member, a female connectinto sleeve 5 and has a threaded flange member 6| with aperture 62 threadably engaged to the bottom threaded portion of the connecting member 50. A ball check member 63 seats on the seating surface 64 of the aperture 52 to check the flow of water from the-connecting portion 60. Web member 65 is disposed in the connecting portion 60 to restrain the movement of the ball member 63. The connecting member 60 is connected to any suitable flttingand has outwardly extending locking-pins 66 for locking engagement with the locking portions 13 on the flange 5|. It will be evident from the foregoing description that I have provided a verysimple anti-freezing hydrant in which there is no opportunity for any siphonage to take place or any opportunity for a cross-connection between water supply line and sewer or ground water.

A suitable protective cap member (not shown) may be provided for the connecting member when it is removed from the sleeve 5.

-In operation, the connecting member is projected into the sleeve 5 and a locking connection is made between the locking jaws l3 and the looking pin 66 of the connecting member 50. The

handle or lever 40 is then pushed downwardly 90 degrees, thereby unseating the seating member 28 to permit the flow of water from the supply line 33. "The water from the supply line 33, being of comparatively higher pressure pushes. the ball 63 away from the seat 64 of the aperture 62 in the flange 6|, thereby permitting the flow of water through the connecting member 50 to any suitable hose connection. When it is desired to shut off the flow of water, the lever 49 is raised to an upright position as shown in Fig. 1 to seat the seating memberifi on seat 32 of the flttingS and the connecting member 59 is removed from the sleeve 5 with the ball member 63 automatically engaging the seat 64 of the aperture 62 of the threaded flange member 6|. I provide a cover member ill of semi-spherical shape with a handle H hinged at 12 on the base member l to cover up the lever 40 and the sleeve 5. I

Yarious changes may be made in the specific embodiment of my invention without departing from the spirit thereof or from the scope of the appended claims.
