This invention appertains to new and useful improvements in the general art of water distribution and more particularly to an improved hydrant and mount structure therefor.
The principal object of the invention is to provide a hydrant constructed in sucha manner as to preclude the poss'bility of accidental breaking of the same with the resultant leakage of the Water line.
Another important object of the invention is to provide a hydrant wherein the valve control can be easily locked against operation. 1
Still another important object of the invention is to provide a hydrant having a unique casting forming part of the valve assembly which can be used in various styles of hydrant. Still another important object of tion is .to provide a hydrant wherein a the invendrinking fountain is incorporated in the hose connection.
A further object is to provide a hydrant provided with means whereby draining of the eduction pipe will occur at a point below the automatically upon and whereby the said the valve is opened.
Still another object is frost line closing of the hydrant valve, drain will be sealed when to provide a hydrant assembly which can be readily disassembled for the purpose of repair or replacement of parts.
These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

Figure 9 is a fragmentary vertical sectional view through a modified form of valve assembly. Figure 10 is a horizontal sectional view through the upper portion of the valve plug with the mechanism removed of the form of the invention shown in Figure 9.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents an elongated vertical case having its 10 tion 6 of the provided with cured by suitab concrete base (not sho Extending diametric portion of socket structure valve block 9 is p standing portion. and I2.

e for use, but if it is to be used with the shown in Figure 3, the on 25 is cleared away and one end of the the block is to be used 8 and 9 the obstructing portion 26 is bored out and the partition 25 left rer maining, as one end of the block is then connected with a water utilizing pipe and the other with the supply. In this of the bore II is plugged Otherwise the block instance the upper end as denoted by numeral Be as used in Figure 9 is of the same construction as that in Figure 3 excepting with regard to the removal of the portion 26.
As is clearly shown in Figure 2, the aforementioned valve rod 18 extends upwardly into the barrel 22 and is threaded into the lower end of the tubular connector 28, the lower end of the rod section 29 being threaded into the upper end of the tubular connector 28 providing a means of adjustment of rod line 29 I8. A washer 30 is provided at the lower end of the rod section 29 and interposed between this and the cap 3! is the coiled compressible spring 32. The spring 32 serves to urge the valve rod [8 downwardly maintaining the valve element in seated positiom The top of the cap 3! is provided with the upstanding boss 33 through which the rod section 29 is slidable. The handle 34 of theoperati-ng means is provided with the cam-shaped head 35 which is bifurcated as at 36 to straddle the upper end of the rod section 29 and a pin 37 is disposed through the rod section.29 and bifurcated cam head 35 to connect these parts together.
Obviously, the handle .39 is swung in a vertical plane to operate the cam head 39 against the top of the cap 3i to lift the rod line 29i8 against the tension of the spring 32 to remove the valve from the seat l5, thus permitting water to enter one end or the other of the block 9, to pass through the opening it and into the bore II and up the eduction pipe 38 to the elbow 39, and through this elbow to the post connecting nozzle 48, one end of which isthreaded :as at 4| into the outwardly protruding endjof the elbow 39 While jamb nut 32 is provided at this point along with washer is to prevent any movement of elbow 39 or nozzle dilfrom the device proper. The depending hose connecting end M of the nozzle 40 merges with the latter at a point where an upstanding tubular formation 45 is provided and internally threaded to receive the plug 46, which in turn is provided with a threaded bore for receiving the tubular and externally threaded shank Al of the hand wheel 48. The lower end of this shank 4? is closed, but openings 49 extend through the side thereof, so that when the tubular member 47 is screwed inwardly,'the bore of this member t? will be communicated with the water line through the nozzle All, so that while water is passingthrough the nozzle to a hose (not shown) a workman can actuate the handle 48 and obtain a fountain of water through the threaded shank 41 for drinking purposes.
Thus it can be seen in Figure 2, an eye member 59 is provided on the cap 3i so that a padlock can be engaged with the handle 34 and eye 56 for holding the hydrant valve mechanism in closed position.
Figure 8 of the drawings discloses not only an eye 59a for holding the valve handle in closed position through the agency of a padlock, but also an eye member 591) which with the use of a padlock can be used for holding the control handle 39a in open position against movement.
It can be seen, that when the cam 35 is operated to a valve opened position, the rod I 8 moves upwardly. The barrel 22 (see Figure 2) is moved upwardly until its upper end abuts the cap 3|.
As the cam is moved further the tapered collar I9 rides against the lower end of the barrel 2i and remains in this position as the rod I8 continues to move upwardly through the same carrying with it the packing collar 20 which is now compressed between the collar l9 and the head I I so that it will bulge into the drain openings 20a 26a. Water can now pass upwardly through the eduction pipe or through the outlet side of the form of the invention shown in Figure 9 without any of the water escaping through the drain. However, when the valve is to be closed,
reverse movement of the cam 35 is performed,
lowering the valve element against the seat l5 (see Figure 3) and bringing the groove of the collar IS on to a plane with the drain openings Zuni-20a. The eduction pipe 38 can now drain through the ports 28a29a and around the collar l9, to the inside of the case 5 and out of the bottom of the case through the openings 20b to the area around the base 8 which is preferably a bed of crushed rock or the like so that water can readily flow away from the base 8.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention what is claimed as new is:
1. A hydrant comprising a foundation attachable base plate, a vertically extending case detachably secured to the base and provided with a cap, a vertically extending valve rod, a block structure mounted within the lower portion of the case and having a horizontal water inlet bore therein, said block being provided with a pair of vertical bores one of which communicates with the horizontal bore and the other bore communicating with the last mentioned vertical bore, a valve member seatable in the first named vertical bore and to which the valve rod is connected, a water outlet for the other vertical bore, a sleeve surrounding the rod havingits lower end positioned in said first named vertical bore, drain openings in said first-named vertical bore, an .expa'nsible packing carried by the rod, means on the rod interposed between the sleeve and the packing to expand the latter into the drain opening upon a predetermined opening movement of the valve rod, and operating means at the said cap for the rod.
2. In a hydrant structure, a case, an eduction pipe in the case, a. cylinder having a fluid inlet valve seat at its lower end, said cylinder and eduction pipe being in communication, a plunger slidable in the cylinder, means for moving the plunger vertically in the cylinder, drain ports in the eduction pipe and cylinder, and means on the plunger adapted to expand into the ports to close the same when the plunger is unseated from the said seat, said means consisting of an expansible collar on the plunger and means for compressing the collar automatically when the plunger is moved to unseated position.
