` Claims.

This invention relates to improvements in frost- Jr'oof hydrants, drinking fountains, wash sinks and other like water service apparatus of that type embodying a stand pipe having a discharge .nozzle anda valvemovable to a position for admitting water from a source of supply to the stand pipe for discharge through the nozzle and to aposition for cutting offv the supply of water to the stand, pipe and connecting the standp-ipe with a drain outlet for the drainage ,of` Water from thestand pipe after each water supply action. Ihe combinedwater supply and drain `,valve referred to yis carriedy by a rod or stem ,whichl ex tends .upwardly through the stand pipe and is adapted` to beraised by ahandle or operating device to open the valve for a water supply action and to be lowered to return the valve to normally closed position in which it cuts off the ,supply of water andsimultaneously connects, the stand pipe with the drain outlet. The movement of the valve to openposition in this type vvof apparatus results in a full or maximum flow of water through the nozzle, no provision being made for securing a graduated or regulatedflow. It is desirablein some uses of a frostproof hydrant to securea graduated or regulated dis.- charge of the water without interferingwith the normal operation of -the hydrant for securing la full flow action and also without endangering its frostproof properties. i v

One object of my invention is to provide aconstruction of frostproof hydrant whereby .a full ilow or partial or regulated flow may be secured at will.

Another object of my inventionis. to provide means wherebythe valvemechanism may be operated in the usual manner for a full iiow action and in a different manner for a desired reduced ,l flow action.

Still another object of. the invention is to provide a means whereby an ordinary hydrant valve mechanism may be readily .modified to 4secure a regulated ilow action without material .departure from a commonly used frostproof valve structure .1 Siiflietian, Combinati@ .andarrnementot parts,

Referring now more particularly to the drawings, .I designates a stand pipe which is connected atitsflowery end .with a water service or supply kpipe 2 and is. .provided near its upper 'end with 35 a .water discharge outlet,herein shown in theiorr'n of a discharge nozzle 3. Adjacentits lower end, and at .a suitable elevation above thel pipe l,lthe standpipe l is also provided-with anioutlet 4 ci. for connection with a drainpipe-S. The drain 40 outlet.4 communicates with-the upper portion of a part or section E .of the*y pipe l 4which serves as a valve chamber, in which is, arranged a vertically movable combined water inletand drain valve l.. This valve 1 comprises a lowerv valve 45 member 8 controlling the inlet of'water from the pipe .2 and van upper valve-member 9 controlling the. drain'outlet. 4. The valve member 9 is hol, low or of openworkconstruction and provided above yand below the plane of its seat surface lwith 50 ports l0 and Ilv to allow water toilow between the pipel ,above .the level of the drain .of the'drain valve andthedrain .outlet .or Vthewaterinlet 2 in-,the different positions of the

and fully openedpositions respec- 15` 'I'he valve 1 is connected to the lower end of the main section of a rod or stem I2 extending upwardly through the pipe I to a point substantially in line with the lowerend of an outlet chamber I3 attached to the upper end of the pipe I, which chamber serves as an auxiliary valve chamber and has formed thereon or attached thereto the discharge nozzle 3. 'I'he upper end of this chamber I3, which projects above the nozzle, is closed by a stuffing box I4 provided with a gland or followerfl clamping suitable packing I6 in place. Anf up'per or operating rod section I1 is disposed Within the outlet chamber and extends at its upper end outwardly through the stuffing box. The lower end of thisrodsection I1 is connected to the upper end of the'main rod I2 by a threaded sleeve coupling I3, while the upper, outwardly projecting Y endk of said rodV section I1 carries an operating handle or lever I9, whereby the rod as a whole may beraised and lowered to operate the valve 1. A coiled spring 20 disposed about the rod section I1 between the coupling I8 and the top of the stuffing box or a thimble 2| bearing thereonv serves to hold the rod normally depressed and the: valve 1 in water cut off position. Thehandle or lever I9y has a forked or slotted headporti'on 22 receiving a cap 23 threaded onto the upper end of `the rod section I1, through lwhich rod section, cap and the side walls ofthe slot of th'ef head 22 passes a pin or bolt 24 pivotally mounting the handle on the upper end of the valve rod. VThe head 22 is so pivoted or shaped for engagement with the gland I as to serve as a lifting cam operating when the handle I9 is swung on its pivot from a normally vertical position to a horizontal position to lift the rod against the resistance of the spring 20 and thereby raisethe valve-1 fromwater 'cut out to water let on position, in which action the upper end of the rod section `I1 andcap 23 move in the slot of the head 22. In the upward movement of the valve 1 the drain outlet 4 is closed and communication between the stand pipe and supply pipe 2 established for the flow of water in full volume to the nozzle '3. When the handle I9 is shiftedrback toits normally vertical position the rod isl depressed by the action of the spring 20, the valve 1 being thereby returned to normal position to cut off the flow of water from the pipe 2 and to open communication between'the stand pipe and drain outlet 4 for'the discharge of all residual Water remaining in the stand pipe above the valve 1. In practice the Water supply connections to the standpipe are arranged below the frost line, and this drainage'action ensures that no residual water from a supply action is `allowed to` remain yin the stand pipe to freeze in freezing weather.

,A disadvantagel applying'to water service apparatus of this .character is that when the valve 1 is opened a fullvolume dischargeof water from the nozzle 3` always occurs. At times and Ain certain uses of the apparatus, as when it is desired tosecure the discharge of water in small or varying volume, this is objectionable not only on account of the Waste of water but for many other obvious reasons. yIn order to avoid this objection I provide vmeans whereby after opening of the valve 1 the discharge of lwater from vthe nozzle 3 may be reduced and graduatively controlled', whichl means is of such vconstruction that it does not interfere with or impair the'frostproof control action of the valve mechanism. To this end I provide auxiliary valve means operative by rotation of they valve rod or stem when the valve 1 is open for controlling the discharge of Water through the nozzle 3.

In Figs. 1 to 6, inclusive, I have shown one form of auxiliary valve means for this purpose in which the chamber I3 is provided with a projection or inwardly extending offset 25 and a port 26 dened thereby, which port connects said chamber with the inlet end of the nozzle. For cooperation with said port an auxiliary valve is provided comprising wing like segmental shaped flanges 21 on the 'coupling I8. These flanges are so shaped as to form between them flow passages 28; and each flange 21 is so accurately formed for coaction with the port 26 that when, disposed beneath said port l and turned in either direction it will form a passage of variable size between the chamber and port to graduatively control the flow of water therefrom to the nozzle, while when either passage 28 is'disposed in register with the port a full ow of waterto the nozzle is allowed. In the normal position of the parts one of the valve wings is centrally disposed beneath the port 26 and spaced such a distance therefrom that when the handle I9 is operated to lift the valve 1 to open position the said valve wing vwill bebrought close to but not in full closing relation to the port. By this means the ow of water to the nozzle willbe reduced to a minimum service rdegree but not entirely cut off. By rotation of the handle I9, in the horizontal positionjto which it has been moved in lifting the valve 1, the` valveA stem may be turned to the right or left to adjust the acting valve wing to vary the extent of its obstructing surface relative to the port 26, whereby the discharge of water through the nozzle may Vbe graduatively regulated as desired notwithstandgagement therewith of 'a flanged clampingring 29 threaded onto the casing andwherebyv the stuffing box is held from outward displacement'.

This stuffing box conforms generally, so far as its packing features are concerned, with the structure shown in Figs. I to 6, inclusive,`and its similar parts are correspondingly numbered. This box I4a, however, is formed with a depending shell30 provided in its side with a port 3l facing the nozzle and having an annular bottom wall 32 formed with sets of valve ports 33. The coupling member Ia in this construction has a circular flange or valve disk 34 provided with arcuate slots 35 for cooperation with the sets of ports 33 to secure a graduative discharge action. The shell 30 may be provided with a spline or key projection 36 to engage a seat groove 31 in the casing for holding the shell from rotationand ensuring accurate positioning of the valve ports 33. The

` operation with this construction is the same as that described with respect to the construction shown in Figs. 1 to 6, inclusive, for the purpose of obtaining a graduative discharge of the water.

In both forms of the auxiliary valve means disclosed the construction and range of movement of the auxiliary valve member on the rodtoward the stationary valve member inthe auxiliary valve casing i's'such that in the maximum to the nozzle as long as valve 'I is open and in the fullest ow obstructing position of the auxiliary valve. Thus in the event that the handle should not be returned to normal position after a discharge action, that fact will .be vvisually indicated by the flow of a small amount of water from the nozzle, ensuring attention being given to cut oil the flow by returning valve 'I to closed position for a drain action and to'prevent freezing of the hydrant during freezing'weather. My invention thus provides in addition to its advantageous features described a simple safeguard against the valve 'l being left open through oversight after use of the hydrant, whereby the frostproof property of the hydrantrstructure is maintained and preserved.

From the foregoing description,v taken in connection with'the drawings, the construction, mode of operation and advantages-of my invention will be readily understood, and it-will be seen that the invention provides a frostproof hydrant or other frostproof water service apparatus whereby either a full or graduative discharge of water from the discharge nozzle may be secured at will and by the provision of a simple and eiilcient type of means for the purpose. vAlso it will be seen that the invention provides auxiliary valve means for a graduative water discharge action which may be employed without interfering with the normal operation oi the hydrant and without endangering its frostproof properties. It will further be seen that the invention provides auxiliary means for a graduative flow discharge action which may be applied to and employed in conjunction with the parts of an ordinary hydrant valve mechanism and without material departure from approved types-of frostproof hydrant or like water service structure. While the construction is such that the customary return of the operating handle to normal position after a water supplying action ensures that the main valve will be returned to water cut off and drain position, the invention further safeguards the apparatus against liability of freezing'by providing a means for indicatingwhether or not the main valve has been returned to cut off position, thus enabling measures to be taken to prevent freezing in case that through carelessness or inattention on the part 'of kthe operator the operating handle should be left in valve opening position.

It will, of course, be understood that while I have shown certain embodiments of myvinvention for purposes of exemplication, changes in the form, details of construction and arrangement of parts may be made within the scope of the l appended claims without departing from the spirit or sacrificing any of the advantages of the invention.
